Vertical Classroom Unit Ventilator750 CFM to 1500 CFMDecember 2018UV-PRC003Q-EN Product Catalog ©2018 Ingersoll Rand UV-PRC003Q-EN IntroductionAcademic performance of U.S. students depends, in part, on the ability to create a comfortable, learning-friendly surrounding. Being too hot or too cold could hinder a students ability to achieve academic excellence. Seasonal changes, mechanical/building disrepair, and even class attendance provide real challenges to HVAC mechanical systems. The only thing consistent about today’s classroom is its ability to constantly change. With this in mind, Trane’s classroom unit ventilator is designed to support today’s changing environment.Classroom unit ventilators have been cost effective way to heat and cool schools for over half a century. Many schools choose classroom unit ventilators because of their ability to heat, cool and ventilate, as well as their durable cabinet design and small foot print. Because the unit ventilator is a single-space system, one unit installed in the classroom handles only that room’s airflow, thus minimizing the potential for cross contamination between classrooms.Trane’s commitment to providing premium quality products has led to the exclusive use of Electronically Commutated Motors (ECM) in all unit ventilator models. These brushless DC motors incorporate the latest technology for optimized energy efficiency, acoustical abatement, maintenance free and extended motor life. Each motor has a built-ifor programmability, soft ramp-up, better airflow control, and serial communication.Figure 1.Vertical classroom unit ventilatorFigure 2.Back view of unit ventilator direct-drive fansRoomy end-pockets forBlow-thru design providesfreeze protection, sound attenuation, and safetyAuxiliary drainlower sound levelsOff-the-shelf P-trap UV-PRC0

Figure 3.Durable, industrial-grade metal stands up to the toughest classrooms UV-PRC003Q-ENFeatures and Benefits AccessibilityThree-Panel Accessnomically safe for lifting/removal, and allows speedy set up during field commissioning. This design allows for the end pocket of the unit ventilator to be open while the fan (airside) section stays closed. The panel design provides easy access for filter change-out.Top access to the unit-mounted fan speed/sensor option was developed with the teacher or administrative staff in mind. Access to the sensor may be made through a lock/key, or through an easy open door.Piping PackageHydronic piping for the unit ventilator may be factory installed or field provided. It fits freely inside the unit end pockets, for quick hook-up during the installing phase. The motorized valves include a trouble-free, pop-top allowing the maintenance or service technician access to thremoving the valve body from the piping package.Hinged Control BoxThe hinged control box design maintains easy access to the electrical for connection while supporting less potential for damage on the job site from the different construction trades.Spacious End PocketsEasy access to piping and controls is made through the roomy equipment end pocket design. The coil headers and drain connections are made within the unit chassis, freeing-up valuable space in the end pockets for piping or field add-ins. This also grants a tighter seal to prevent air leakage. The roomy end pocket design allows for application requirements such as an optional auxiliary drain pan. The auxiliary pan may be placed under the factory or field piping package. Sliding Fan DeckConvenient access to the fan motor and fan wheels for mainte

nance and serviceability is made in part of the easy-slide design of the unit ventilator fan board. The fan board assembly offers hassle free access to the contractor or maintenance technician. As an added benefit, Trane’s unit ventilator includes electronically commutated motors (ECM) as standard. UV-PRC003Q-ENFeatures and Benefits Engineered for Good IAQIndoor air quality (IAQ) is a top priority in classroom design. Giving students a healthy place to learn and develop is crucial in every school district. It is also crucial to maintaining the building’s overall construction and furnishings. Several features of Trane’s unit ventilator attribute to improved IAQ. Removable Drain PanThe unit ventilator drain pan is dual sloped for effective condensate removal. This non-corrosive pan eliminates the problems associated with leaking or standing water and is removable for Ease of MaintenanceInternal components such as the fan and coils are accessible on and cleaning. Maintaining a clean system increases the efficiency of the unit and is important to good, sustainable indoor air quality. This design also places the coils farther away from the outside air opening, virtually eliminating the potential for coil freezing and the added hassles of nuisance freeze-trips.Damper DesignOA/RA Damper DesignOA/RA ActuatorFigure 4.OA insulated damperThe outside/return air damper is a one-piece design which is linkage free resulting in a superior air seal. This results in lower infiltration of outside air during off cycles thus lowering the risk of freezing equipment in the winter or the intrusion of humid air into the building during the summer.Figure 5.OA/RA actuatorThe OA/RA actuator provides true spring return operation for positive close-off of the OA/RA damper. The spring return system of the actuator closes

the outside damper if power is lost to the building. When ordered with factory controls, the actuator is a 3-point floating design. A 2 to 10-VDC actuator is also available when other than Trane controls are specified. UV-PRC003Q-ENFeatures and Benefits FiltrationVertical classroom unit ventilators utilize an off-the-shelf filter design to reduce or eliminate stocking filters in the school. See General Data section for standard filter sizes.They come equipped with a standard-size throwaway filter to support job site installation and start-up. Trane unit ventilators are designed to accommodate a MERV8 or MERV13 high capacity filter to provide greater filtration of airborne contaminants.Trane unit ventilators provide a broad range of dehumidification solutions. Active humidity control involves monitoring and managing both the dry bulb temperature and the humidity in the classroom. With this strategy, a reheat coil is placed downstream of the cooling coil to temper (reheat) the cold, dehumidified air leaving the cooling coil to avoid over-cooling the space. Reheat configurations are available in a variety of coil combinations.Alternately, the Tracer® UC400-B or Tracer® ZN520 controller can be configured to automatically reduce the fan speed at part-load conditions. This helps improve the coincidental dehumidification performance of the unit at part-load, and also lowers sound levels. To help ensure proper ventilation in the classroom at lower fan speeds, the controller adjusts the outside air being supplied to the classroom.Energy EfficiencyTrane’s commitment to providing premium quality products has led to the exclusive use of Electronically Commutated Motors (ECM) in all unit ventilator models. These brushless DC motors incorporate the latest technology for optimized energy efficiency, acous

tical abatement, maintenance free and extended motor life. Each motor comes with a VelociTach™ motor control board that allows for programmability, soft ramp-up, better airflow control, and serial communication. Trane units equipped with ECMs are significantly more efficient than permanent split capacitor (PSC) motors or belt-drive motors and enable single-zone VAV control.Single-zone VAV control varies the fan speed as the zone cooling or heating load changes, and can result in lower operating costs and improved occupant comfort compared to constant-speed units.The reduced FLA option allows units to ship with a nameplate FLA rating much lower than a typical ECM unit.EconomizerA big advantage of this system is the ability to provide energy savings through an economizer cycle. During mild seasons outside air is used to provide “free” cooling, thereby, minimize or eliminate the need to run mechanical cooling equipment. To truly have an effective economizer a Unit Ventilator must be able to bring in up to 100percent of the design airflow through the outside air damper opening. Trane Unit Ventilators are tested and certified to exceed the industry standard, as defined by AHRI840, for economizer effectiveness. This ensures the school will realize the energy savings available through the economizer strategy.Face-and-Bypass ActuatorThe face and bypass damper actuator incorporates a direct couple design. It provides electronic protection against overload. A limit switch is not included, nor required as part of the design. When reaching the damper end position, the actuator automatically stops. The gears can be manually disengaged with a button on the housing. UV-PRC003Q-ENFeatures and Benefits AcousticsQuiet systems are extremely important in today’s classrooms. Trane offers many different system

requirements of sound, cost, IAQ and efficiency. The Trane vertical unit ventilator takes a comprehensive approach to delivering one of the quietest units available.Fan and Blower Motor AssemblySeveral innovative ideas have gone into the quiet design of the Trane vertical unit ventilator. The fans diameters have been maximized to reduce the motor rpm and thus lower the noise, while still maintaining the cfm requirements to support ventilation and capacity requirements. The unique direct-drive fan and blower design diminishes vibration from occurring further ensuring quiet operation.Quiet Blow-Thru DesignThe Trane blow-thru unit design enables additional sound attenuation by eliminating the fan noise from entering the space directly. The position of the internal components is optimized to enhance The performance and casing construction of Trane vertical unit ventilators further adds to this acoustically superior design. ControlsTrane offers a broad range in control packages to fit both retrofit and new applications. From the field convertible end-device package to a complete building automation system, Trane controls integrate the highest quality components within the unit ventilator to allow greater optimization of the entire system.Fan Speed ControlTrane provides the capability to vary airflow for suitable applications either with three speeds or with a 0 to 10VDC input. This lowers the sound in the space and improvesin the cooling season at part-load. With field installed controls, this is accomplished with a unit-mounted manual fan speed switch or variable speed control with a 0 to 10VDC input. ECM controls provide a soft ramp between speed changes—a significant contributor to overall quiet operation.With the inclusion of the Tracer® UC400-B unit controller, the speed of the fan is infini

at need to be woven into today’s school designs. Therefore, it is important that designers of these systems have accurate information to make system decisions. That is why the industry has developed performance standards and certification programs which ensure that the equipment information provided to the design community is correct and comparable across different manufacturers. The following list of certifications and standards identifies the commitment by Trane to providing the highest quality equipment and information to our customers:AHRI-840ULTested in accordance to AHRI350 (acoustics)BACnet®LonMark® International (ZN520)BTL (UC400-B) UV-PRC003Q-EN Application ConsiderationsSupplying proper ventilation to a classroom is challenging. The various rooms that make up a school are forever changing their ventilation needs, and building occupants and their activities generate pollutants that heighten the ventilation requirements. Students are constantly moving from room to room, and because of this intermittent occupancy, the ventilation frequency of a ntly on the move.Ventilation systems dilute and remove indoor contaminants, while mechanical heating and cooling systems control the indoor temperature and humidity. Supplying an adequate amount of fresh air to an occupied classroom is necessary for good indoor air quality. IAQ should be considered a top priority in the school environment because children are still developing physically and are more likely to suffer the consequences of indoor pollutants. For this reason, air quality in schools is of particular concern. Proper conditioning of the indoor air is more thanencompasses the safety and stewardship of our investment in the students, staff and facility.The tor is its ability to provide heating, cooling, ventilation and dehumidific

Electric heat and steam options are also avions. A direct expansion coil with heat pump or heat recovery variable refrigerant system may be used.Figure 6.System design for the classroom unit ventilator Classroom unit ventilator UV-PRC003Q-ENApplication Considerations When there is seasonal heating and cooling, a two-pipe chilled water/hot water changeover system may be applicable to the mechanical design. This system requires a chiller and a boiler to support the changeover necessity. However, where space constraints may present a concern, the unit ventilator may be equipped with a DX coil for cooling, with an auxiliary electric heat coil, hot water coil, or steam coil for heating.Four-pipe chilled water/hot water systems are also available. This system is typically applied when both heating and cooling may be simultaneously called for in the school.Building AutomationAs part of the building automation system, the mechanical HVAC system equipment may be optimized to lower energy consumption. By running only the mechanical devices that are required to support the building load at a given time of day or night, true energy consumption savings may be achieved.Maintenance and service information through the unit sensing devices are easily defined and cured with an automated system.With factory shipped direct-digital controls, installation and start-up of the sy

stem are more simple.CondensateProper condensate trapping is required for the classroom unit ventilator’s with hydronic and direct- expansion (DX) coils (steam coils do not require a trapped condensate setup). In a properly trapped forms during normal operation, the water level in the trap rises until there is a constant flow of water through the pipe. It is imperative to maintain water in the trap, and not allow the trap to dry out during heating season. Equipment should be installed level to avoid condensate build-up around the coil.PerformanceApplication of this product should be within the catalog’s airflow and unit performance. The Trane Official Product Selection System (TOPSS™) will aid in the selection process for a set of given conditions. If this program has not been made available, ask a local Trane account manager to supply the desired selections or provide a copy of the program.Freeze ProtectionThe most important advantage the Trane blow-through design provides is additional protection against coil freeze-up. In contrast, draw-through configurations allow little mixing of the return and outside air stream while locating the coil very close to the outside air inlet. This process creates “cold spots” on the coil which could lead to coil freeze-up.With a blow-through design, face and bypass with isolation valve control is not necessary to provide proper freeze protection to the unit vent. The placement of the coil above the fan allows enough space for the coil to avoid “cold spots” that could cause freezing.School institutes contain a diverse day of activities that have a potential including cafeterias, art and science classrooms, vocational education areas, pools and locker rooms. Proper ventilation, filtration, and maintenance of these spaces can pose some challenges.Occupant den

15 sity in classrooms is much higher than t
sity in classrooms is much higher than that found in office or retail spaces. The amount of outdoor air required to ventilate a classroom is based predominantly on the number of students expected to occupy the space. Students also move in large groups, frequently throughout the building, resulting in widely varied thermal loads within the zones. To compound the situation, a classroom mechanical system is typically run for 9months of the year, and vacated for 3months (either by turning up or off the HVAC system). To increase the IAQ challenge even more, building UV-PRC003Q-ENApplication Considerations construction techniques that help reduce energy costs, also tightly seal the school. This can lead to uncirculated/unfiltered air.VentilationVentilation is an important factor in maintaining healthy air. In a poorly ventilated school building, fumes and vapors are not properly exhausted allowing particles to develop. A healthier building is a building where the air is exchanged more frequently and properly filtered. Through ventilation, stale indoor air is exhausted and fresh treated outdoor air is drawn into the building. The amount of ventilation air required is established by building codes and industry standards. Most building codes reference ASHRAE Standard62Ventilation for Acceptable Indoor Air Qualityas the minimum requirement for ventilation system design. Architects, engineers and contractors utilize this standard when determining and calculating the type of load the building environment will place on the mechanical system.FiltrationTrane unit ventilators are tested and designed to exceed ASHRAE Standard62. This includes the use of a higher efficiency filtration to help introduce proper levels of “fresh” diluted air for contaminant removal.MaintenanceBeyond the ventilation and filtrat

Enhancements to support superior IAQ performance include:Coil presentation allows for ease of maintenance and cleaning.A dual sloped non-corrosive drain pan (removable) helps keep moisture in the system to a minimum.Ultra low leak damper that results in a fixed air seal of the damper assembly.Air exchange performance that goes beyond code while maintaining the AHRI-840 certification for economizing requirements.An upgrade-able MERV rated filters help reduce contaminants and increase filtration.Side-wall power exhaust support system to help remove the stale air from the classroom and better support the air exchange.Energy recovery unit ventilator to further pretreat and dehumidify the fresh air before it enters the classroom unit ventilator.Options for improved dehumidification at part-load, including automatic fan-speed control, face and bypass dampers, and active humidity control through reheat. UV-PRC003Q-ENApplication Considerations Energy OptimizationIndustry StandardsThe Air-Conditioning, Heating, and Refrigeration Institute (AHRI) created the AHRI-840 standard for classroom unit ventilators to provide a consistent method of rating the unit ventilators design performance. To achieve AHRI-840 certification, the unit ventilator must be capable of providing a minimum of 80percent of its ventilation (airflow) through the outside air economizer function. This measurement ensures that the expected energy savings by the economizer is realized in actual operation. Only AHRI-840 certified equipment has been independently tested for compliance to the minimum requirement. Trane was the first, and continues to be one of the few manufacturers that meet this certification. By meeting this certification

, the designer can be assured that the Trane unit ventilator will perform with energy conservation in mind.AcousticsA growing population, and an increase in economic pressure to maximize building footprints have resulted in higher building occupancies and less space to place the HVAC equipment. Often times the close proximity of the equipment—such as a floor mounted unit ventilator—may cause noise related complaints. Reducing the likelihood of these complaints requires careful planning:Equipment sizing (under sizing and over sizing could increase noise level)Equipment placement (absorption and number of sound sources in the room greatly affect noise)Figure 7.Unit ventilator economizerThe energy consumption of a unit ventilator system can be significantly reduced through the use of an economizer cycle. To better understand the basic function of how an outside air economizer works, it is important to fully understand how it operates.The economizer functions by opening an outside air damper, and bringing cooler outside air into the space. The economizer cycle is controlled with a modulating damper motor, which opens at specified increments dependent upon readings from outside air sensors.Economizers also utilize a return-air damper that closes as the outside air damper opens. Depending on the room requirements, the modulating damper motor may mix the return air with the outside air to provide the maximum energy cost efficiencies without sacrificing comfort.When the room thermostat calls for cooling, the economizer control provides the right mix of outside and return air to cool the classroom. The equipment’s airflow is generated from both fan energy and the economizing dampers. This design supports optimum ventilation and provides the greatest energy savings. As the outside air temperature ri

18 ses (typically above 55°F), the outside
ses (typically above 55°F), the outside damper closes to the minimum position, activating the second cooling stage on the room thermostat—the cooling-generating device (compressor, water pump, chiller, cooling tower). The return-air and outside air dampers modulate to support the discharged air temperature.Dampers working together with the cooling coil is called integrated economizing, which allows a unit ventilator to mix outside air with return air, delivering an energy-efficienton to a school.

Given the complexity of various building systems, it is extremely important to assure that the design goals (commissioning) for classroom acoustics, IAQ, and moisture control are met through all aspects of the space.For example, it is not uncommon for a school to install unit ventilators that are manufacturer-rated for a specified airflow (cfm), but which are not AHRI-840 certified. These units may ship with a fan-speed setting that delivers a lower than specified airflow, perhaps to reduce sound levels. Without an overall building design goal, these units will be installed without delivering the specified airflow needed to support the fresh air circulation, and possibly compromise IAQ. Unless the equipment is tested at the specified airflow, it is extremely difficult to determine whether the unit meets the specified sound level.Trane’s unit ventilator will not compromise air quality to support a minor reduction in airflow noise. We encourage our engineers to specify their airflow needs at full building load requirements. Fine-tuning of the speed setting may be interchanged through the unit’s 3-speed fan sensor quickl

y and easily. This mechanical feature ensures that the equipment supplies proper cfm to support IAQ in the classroom, while giving complete control of equipment noise to the administrative staff. Acoustic EnhancementsTrane direct digital controls (Tracer ® UC400-B) is another way to control airflow noise. With the Tracer® UC400-B controller, an infinitely variable speed fan control for the unit ventilator delivers the airflow output customized to support the cfm space needs. When less cfm is necessary to meet the load of the classroom, the equipment operates at an optimum speed, keeping sound levels to a minimum. Another solution for acoustically sensitive applications is the option for “Low Acoustics,” which uses the ECM technology to manage the fan speeds. However, if the room temperature rises above the setpoint, the controller will switch to high speed for sustaining the space needs. As part of this strategy, ventilation must also be considered. The Tracer® UC400-B controller will reposition the outside air damper to confirm the minimum outside air cfm is met at both operating conditions. This setup allows the unit ventilator to meet the space comfort condition, while providing a lower sound levels and proper ventilation.Figure 8.Equipment placement UV-PRC003Q-ENApplication Considerations Humidity ControlA typical unit ventilator is a constant-volume, variable-temperature device. It uses a constant fan speed and modulates water flow through a chilled water coil to maintain the dry bulb temperature in the space based off of a setpoint. Outdoor air is introduced at the back of the unit ventilator, and distributed with the supply air. At design cooling load conditions, a system controlled in this manner typically has a leaving air temperature that is cold enough (and, therefore dry enough)

to sufficiently dehumidify the space, but its ability to dehumidify can decrease significantly at part-load conditions.When the sensible load in the space decreases (part-load), the constant-volume system responds by raising the dry-bulb temperature of the supply air. In a chilled water unit ventilator, this is accomplished by modulating a valve to reduce the rate at which water flows through the coil. Figure9 shows how this affects the supply air leaving the coil—the warmer coil surface that results from less water flow provides less sensible cooling (raising the supply air temperature) and removes less moisture from the passing air stream.The sensible cooling capacity of a constant volume system decreases to match the smaller sensible cooling load. Any latent cooling (dehumidification) capacity is purely coincidental, whether the cooling-coil medium is chilled water or refrigerant. As the load diminishes, the system delivers even warmer supply air. Some dehumidification can occur in this situation, but only if the sensible load is high enough.Some designers attack this problem by oversizing the unit ventilators. This does not solve the problem; in fact, it can make the situation worse. Increasing the capacity of the unit ventilator may also require increasing the supply airflow. A higher-than-necessary supply airflow results in warmer supply air and, in non arid climates, less dehumidification. It’s important to understand, this is not just a unit, coil, or fan-sizing challenge. Rather, it’s an issue of properly controlling the system in a manner provides sufficient dehumidification at all operating conditions. Proper dehumidification with terminal units is a matter of proper controlActive Humidity ControlA common method used to address this part-load humidity control challenge in a consta

nt-volume system is active humidity control through supply air tempering (reheat). Active humidity control involves monitoring and controlling both the dry bulb temperature and humidity in the occupied space. Whenever the space humidity is below the preset upper limit (typically 60percent relative humidity), the system operates just like a normal constant-volume system. However, if the space Figure 9.Part-load dehumidification with modulated chilled water UV-PRC003Q-ENApplication Considerations humidity reaches or exceeds the upper limit, the cooling coil control valve is driven open regardless of the need for sensible cooling in the space. The coil over-cools the air, increasing the dehumidification capacity of the system.With this control sequence, a reheat coil is placed downstream of the cooling coil to temper (reheat) the cold, dry air leaving the cooling coil in order to avoid over-cooling the space. The key to cost-effectively applying an active humidity control system is to use reheat only when it is needed. This requires the sensing of both the humidity and temperature in the occupied space.When the space humidity falls below the upper limit, the system remode and again operates as a traditional constant-volume system. Basic components of a Trane reheat system include:Classroom unit ventilator with a main ary coil downstreamTracer® ZN520 digital controllerTwo sensors, one for the temperature and one for relative humidity; sensors may be located in the zone or in the return air streamIf after hours operation is required, the addition of a building automation system (BAS) such as Tracer Summit™ is recommended to coordinate the chillers, pumps, boiler and unit ventilators. It also assures proper operation of the exhaust fans.Figure 10.Basic components of active dehumidification con

In this case, the recovered energy is the by-product of a cooling process which would normally be rejected or wasted. A common example may include a plate and frame heat exchanger in the condenser water loop of a water-cooled chiller system.Automatic Fan-Speed AdjustmentReducing the fan speed (supply airflow) at part-load conditions is a way to improve the coincidental dehumidification performance of a unit ventilator. The Tracer® ZN520 digital controller can be configured to automatically reduce fan speed when the sensible load is decreased, Figure13, p.20At full load, the fan operates at high speed and the control valve’s flow is wide open. As the cooling load decreases, the controller modulates the valve to throttle the rate of chilled water flow through the coil. At some point, based on valve position, the unit controller switches the fan to low speed. Less airflow means that colder supply air is needed to maintain the target space temperature. The control valve opens allowing the coil to remove more moisture from the passing air stream.The controller will also adjust the outside air datilate the classroom at the lower fan speed condition.Figure 11.Reheat system Temperatureunit ventilato r UV-PRC003Q-ENApplication Considerations Face-and-Bypass DampersFigure 12.Auto fan speed adjustment Valve positionControl valve Low 020406080100 Fan speed High Figure 13.Face and bypass damperFace-and-

The bypass is sized to have the same pressure drop as the cooling coil so that a constant air quantity can be maintained at all times during system operation.the dry bulb temperature in the space by modulating the amount of air flowing through the cooling coil, thus varying the supply air temperature to the space. As the face and bypass damper begins to close some of the outside/return air mix is diverted around the coil and mixed with air coming off the coil to obtain a supply air temperature that is proportional to the reduction in space load. Because the chilled water valve remains wide open, the portion of the air passing through the coil is dehumidified further, improving part-load dehumidification.However, face and pass control does not actively control space humidity. It still allows the space humidity level to rise at part-load, often higher than For more information on various methods for improving dehumidification performance of unit ventilator systems, refer to Trane “Dehumidification in HVAC Systems” application manual SYS-APM004-EN. Face-and-bypass UV-PRC003Q-ENApplication Considerations Dynamic Air BarrierDuring the cooling season, the drier, sensible heat and moisture transfer from the outdoor air to the cooler, drier exhaust air. Conversely, during the heating season, sensible heat and moisture transfers from the exhaust air to preheat and humidify the entering outdoor air stream. Figure15psychrometric ally depicts the impact of a preconditioning total-energy wheel on a unit ventilator.This approach can’t directly control humidity in the space, but it can significantly reduce the capacity (and operating cost) of t

he cooling and heating equipment required to condition the outdoor air. Capable of recovering 65 to 75percent of the energy in the exhaust air stream, total-energy wheels used in conjunction with unit ventilators can be an attractive alternative when upgrading existing classroom to meet ASHRAE’s ventilation requirements; they reduce, perhaps even eliminate, the extra capacity needed at the chiller plant or boiler.The Trane energy recovery unit ventilator (ERS) is one example of a “cold coil” unit with outdoor air preconditioning.Both preconditioning (energy recovery) and post conditioning (reheat) may be applied in the same system. Figure 14.Dynamic air barrierIn areas that contend with colder climates for a significant period of time, a school may wish to employ a dynamic air barrier package. With this dynamic (draft) barrier system, the cold air is captured off of the window, and drawn into the classroom unit ventilator’s normal airflow cycle. The unit ventilator treats/warms the air as if it were part of a return-air makeup system. This captured air is then discharged into the space providing comfort to the classroom’s occupants.This draft barrier shield should be utilized when:Almost 50percent of the wall includes windows.Outside air temperatures fall below 35°F for a significant period of Or, in retrofit applications where the windows are of a single pane thickness.

The exact method of controlling the amount of outside air and heating capacity can vary. However, all systems provide a sequence of operation designed to provide rapid classroom warm-up and increasing amount of ventilation air to offset classroom load.To help supply proper ventilation to these fluctuating heat gains, the Trane unit ventilator is designed to provide rapid classroom warm-up and increasing amounts of ventilation air to offset classroom overheating.Figure 16.Cold coil with outdoor air preconditioning UV-PRC003Q-ENApplication Considerations Figure 17.ASHRAE cycle graphASHRAE Cycle IAll standard unit ventilator cycles automatically close the outside air damper whenever maximum heating capacity is required. As room temperature approaches the comfort setpoint, the outside air damper opens fully, and the unit handles 100percent outside air. Unit capacity is then controlled by modulating the heating element capacity.ASHRAE Cycle I is typically used in areas where a large quantity of outdoor air is required to offset the air being exhausted to relieve the room of unpleasant odors and particles.ASHRA

E Cycle IIASHRAE Cycle II is the most widely used ventilation control. Similar to CycleI, the outside air damper is closed during warm-up. But with CycleII, the unit handles recirculated air through the return air system. As temperature approaches the comfort setting, the outside air damper opens to admit a predetermined minimum amount of outside air. This minimum has been established by local code requirements and good engineering practices. Unit capacity is controlled by varying the heating output. If room temperature rises above the comfort setting, the heating is turned off and an increasing amount of outside air is admitted until only outside air is being delivered.ASHRAE CycleII is a very economical control sequence often referred to as integrated economizing. This design supports optimum ventilation and provides the greatest energy savings. This is further proof of why AHRI-840 certification is important in minimizing energy consumption through economizer performance. UV-PRC003Q-EN Selection ProcedureTrane vertical classroom unit ventilators provide air delivery and capacities necessary to meet the requirements of modern school classrooms. They are available with the industry’s widest selection of coils to precisely satisfy heating, ventilating and air conditioning loads with the best individual type of system. Unit ventilator selection involves three basic steps.Determine the classroom/space unit cooling and/or heating loadsDetermine the unit sizeSelect the coilCapacity RequiredThe first step in unit ventilator selection is to determine room heating and air conditioning loads. The calculation of this load is essential if the equipment is to be economical in first cost and Adequate ventilation is mandatory in classroom air conditioning design. The amount is often specified by loca

27 l or state codes and, in air conditioned
l or state codes and, in air conditioned schools, may be either the same or less than that specified for heating systems. The usual requirement is between 15 and 25cfm of outside air per occupant, based on the intended use of the room. For instance, a chemis normally requires more ventilation for odor control than a low occupancy speech clinic.Ventilation is an important concern and should be accurately determined to assure good indoor air quality. Purposely oversizing units should be avoided, since it can cause comfort and control Unit SizeUnit ventilator size is determined by three factors:Total air circulationVentilation cooling economizer capacity requiredTotal cooling or heating capacity requiredTotal air circulation, if not specified by code, should be sufficient to ensure comfort conditions throughout the room. This is usually from six to nine air changes per hour, but can vary with room design and exposure. Often rooms with large sun exposure require additional circulation to avoid hot spots.Ventilation cooling capacity is determined by the amount of outside air delivered with the outside air damper fully open, and the temperature difference between the outside air and the classroom. In air conditioning applications, ventilation cooling capacities should maintain the comfort setting in the classroom whenever the outside air temperature is below the unit or system changeover temperature.Example:Ventilation cooling capacity = 1.085 x cfm - T = Total air capacity of unit with outside air damper open 100percent. = Room temperature. = Outside air temperature.In classrooms with exceptionally heavy air conditioning loads, unit size may be determined by the total cooling requirement. Good practice dictates 375 to 425cfm per ton of hydronic cooling capacity. Normally, however, Tranioner co

A complete list of controller inputs and outputs are in Table48, p.67. See Table53, p.80 for information on end device options.Customer Supplied Terminal Interface (CSTI)The CSTI is intended to be used with a field-supplied, low-voltage thermostat or controller. The control box contains a relay board which includes a line voltage to 24-volt transformer and disconnect switch (for non-electric heat units). All end devices are wired to a low-voltage terminal block and are run-tested, so the only a power connection and thermostat connection is needed to commission the unit. Entering water temperature sensors and controls are provided whenever a changeover coil is selected. When N.O. valves are selected, inverting relays are provided for use with standard thermostats.The CSTI adapter board provides all the hookups as the standard adapter board, but in addition, provides hookups for valve control (main and auxiliary coils), electric heat control, and damper control. Screw terminal blocks provide convenient access to fan controls and to end device control. In addition, a courtesy 10-VDC supply is provi

Each unit is capable of functioning independently of one another during occupied and unoccupied hours of the day. This allows the temperature setpoint and ventilation setting to be changed automatically based on usage. See Figure27Figure 26.Tracer® ZN520 control boardThe Tracer® ZN520 controller is a factory-installed, -tested and -commissioned LonTalk control designed to provide control of Trane products.

74 V-PRC003Q-ENControls Two Systems in OneI
V-PRC003Q-ENControls Two Systems in OneIn a Tracer® system environment, the Tracer® ZN520 is pre-designed to install quickly and easily into the system. Since the controller and the unit are factory tested and commissioned, the start-up time for the entire system is minimized. Trane becomes the single source of responsibility for the equipment, unit controls, and building automation system.As a standalone controller, the Tracer® ZN520 is ideally suited for fix-on-fail replacement of units with old pneumatic controllers, or in situations where a BAS will be added at a later date. Once power is applied to the controller, it will automatically start up and run based upon the setpoint on the local zone sensor. An individual time clock can be added to the unit for local scheduling. The Tracer® ZN520 is certified to the interoperable LonMark Space Comfort Controller profile. This allows the controller to be used with another vendor’s BAS and thereby still provide the high quality of factory installation and testing. In addition, the Tracer® ZN520 provides one of the most extensive interoperable data lists of any controller of its type in the industry.Figure 27.Tracer® ZN520 system UV-PRC003Q-ENControls Tracer® UC400-B ControllerFor optimal system performance, units can operate as part of a Tracer® SC building automation system. The controller is linked directly to the Tracer® SC via a twisted pair communication wire, requiring no additional interface device (i.e., a command unit). The Tracer® control system can monitor or override Tracer® UC400-B control points.This includes such points as temperature and output positions.Tracer® Controller FeaturesThe Tracer® family of controllers offer the combined advantages of simple and dependable operation with the latest Trane-designed controller. Standard

75 control features include options normal
control features include options normally available on more elaborate control systems. All control options are available factory-configured or can be field-configured using Rover or Tracer® TU service software. For more detailed information, refer to Trane installation manuals CNT-SVX04*-EN (for Tracer® ZN520), or BAS-SVX48-EN (for Tracer® UC400-B).The following control functions are standard features on units with Tracer® ZN520 and Tracer® UC400-B.Entering Water Temperature Sampling FunctionA system that uses a two-way control valve option might not sense the correct entering water temperature during long periods when the control valve is closed. If the demand for heating or cooling does not exist for a long period, the entering water will eventually approach ambient temperature.Using the entering water temperature sampling function, the controller provides accurate two-pipe system changeover-without sacrificing the benefits of two-way control valves. Also, it eliminates inefficient bleed or bypass lines that can allow unnecessary waterflow through the system. This function periodically samples the entering water temperature by opening the hydronic valve. The valve opens for 20 seconds to allow the water temperature to stabilize.Then the controller reads the entering water temperature for up to three minutes to see if the correct water temperature is available for the selected operating mode.The entering water temperature must be five degrees or more above the space temperature to allow hydronic heating and five degrees or more below the space temperature to allow hydronic cooling. If the correct water temperature for the operating mode is available, the unit begins normal heating or cooling operation. If the correct water temperature is not available, the the control valve and waits 60 mi

Figure 28.Tracer® UC400-B controllerThe Tracer® UC400-B single-zone VAV controller can be used in a stand-alone application or as part of a Tracer® control system. In the stand-alone configuration, Tracer® UC400-B receives operation commands from the zone sensor and/or the entering water temperature sensor (on auto changeover units).The entering water temperature sensor determines if the unit is capable of cooling or heating. The zone sensor module is capable of transmitting the following information to the controller: Timed override on/cancel requestZone setpointCurrent zone temperatureFan mode selection (off-auto-high-med-low) UV-PRC003Q-ENControls A factory-mounted thermistor senses the entering water temperature on changeover cooling/ heating coil units. If the fan coil has a factory-mounted piping package, the sensor is strapped to the entering water pipe. If the fan coil does not have a piping package, the sensor is coiled in the end pocket for mounting on customer-supplied piping.This sensor must detect accurate water temperature for proper changeover. Automatic Heat/Cool Mode DeterminationThe controller automatically determines whether heating or cooling is needed-based on space and system conditions. Using a proportional/integral (PI) control algorithm to maintain the space temperature at the active heating or cooling setpoint.The controller measures the space temperature and active setpoint temperature to determine the unit's heating or cooling capacity (zero to 100 percent).Occupied/Unoccupied OperationThe occupancy input uses a binary switch (i.e., motion sensor, time clock, etc.) that allows the zone sensor to use its unoccupied internal setpoints.Random StartThis feature randomly staggers multiple unit

Warm-upThe two-position fresh air damper option closes during the occupied mode when the space temperature is three degrees or more below the heating setpoint temperature.The damper remains closed during warm-up until the space temperature is within two degrees of the heating setpoint temperature. Cool-downThe two-position fresh air damper option closes during the occupied mode when the space temperature is three degrees or more above the cooling setpoint temperature.The damper remains closed during cool-down until the space temperature is within two degrees of the cooling setpoint temperature. Manual Output TestThis function may be initiated from the blue test push button on the controller or through the Rover or Tracer® TU service tool.This feature is used to manually exercise the outputs in a defined sequence. The purpose of this test sequence is to verify output and end device operation.The manual output test function may also be used in the following situations: Reset latching diagnosticsVerify output wiring and operationForce the water valve(s) open to balance the hydronic system during installation set-up or service. Peer-to-Peer Communication Peer-to-peer communication allows multiple units in one space to share the same zone sensor and provide simultaneous heating and cooling.TheTracer® ZN520 controller can share information between units on the same communication link using a twisted pair wire in the field. Unit configuration must be modified with Rover service tool.OntheTracer® UC400-B, zone sensor data sharing can be accomplished by use of the BAS system controller.A thermistor to sense fresh air is factory-mounted at the unit's fresh air opening for use in economizer applications or as a read-only point for Tracer® SC or Tracer Su

mmit™. If the fresh air temperature is a read-only value, it will not impact the control algorithm. In an economizer application, a fresh air temperature signal must be provided either by this thermistor, Tracer® SC, or Tracer Summit™. UV-PRC003Q-ENControls Single-zone VAV controlWhen the zone temperature drops to heating setpoint, the fan continues to operate at minimum speed and the DAT setpoint is reset further upward. Heating capacity is modulated or staged to maintain this DAT setpoint. If the zone heating load increases to the point where DAT reaches the maximum limit, fan speed is again increased, while heating capacity is modulated or staged to maintain DAT at this maximum limit. Single zone VAV is not supported on DX coil units.Economizing Control (Tracer® ZN520)With the controller configured for economizing control, it will calculate the required cooling capacity every ten seconds and modulate the damper option open to the calculated position. If the setpoint is not satisfied, the damper will continue to open until the setpoint condition has been met or the damper is 100 percent open. If this still does not satisfy the setpoint, the cooling valve option will begin to open and try to satisfy the load requirements. Onceeds the load requirements, the valve will begin to close until the setpoint has been reached or the damper reaches its minimum position, which is field-adjustable.This option uses a three-wire, floating point damper actuator. A thermistor to sense discharge air is factory mounted near the discthe last coil for use in economizing and cascade temperature control.Tracer® SC or Tracer Summit™ can also use this temperature value as a read-only point. Cascade temperature control uses both the zone and discharge air temperatures to more accurately calculate the required unit

capacity. Automatic Fan and Ventilation ResetA multi-speed fan control for the unit delivers the airflow output customized to support the cfm space needs.When less cfm is necessary to meet the load of the classroom (typically 75 to 80 percent of the time), the equipment operates on low speed. However, if the room temperature rises, the controller will switch to high speed, and the outside air damper will adjust to satisfy the space needs.This helps maintain the proper amount of ventilation air to the occupants independent of the fan speed. As part of the ventilation strategy, the controller will reposition the outside air damper to confirm the minimum outside air cfm is met at both operating conditions. Filter MaintenanceFilter status for the controller is based on the cumulative run hours of the unit fan. The controller compares the amount of fan run time against an adjustable fan run hour (stored in the controller) Figure 29.Single-zone VAV controlSingle-zone VAV control varies the speed of the EC fan motor as the zone cooling or heating load changes. When the zone is at design cooling load, the unit operates the fan at maximum speed and cooling capacity is modulated or cycled to deliver the air at the design discharge air temperature (DAT) setpoint for cooling. As the zone cooling load decreases, fan speed is reduced to maintain zone temperature at cooling setpoint, while cooling capacity (and/or economizer) is modulated or cycled to maintain DAT at the same design setpoint. When the fan has reached minimum speed, and the zone cooling load continues to decrease, the fan continues to operate at minimum speed while the DAT setpoint begins to reset upward to maintain zone temperature at cooling setpoint. Cooling capacity (and/or economizer) is modulated or cycled to maintain this DAT setpoi

The run-hours value may be user edited as required (through Rover or Tracer® TU). The valid range for the fan run hours limit is 0 to 5000hours with a default of 600hours. Once the run hours limit has been exceeded, the controller generates a maintenance required diagnostic (unit will not shut-down). The user will be notified of this diagnostic through the building automation system or when a Trane service tool is communicating with the controller.Active DehumidificationOn units with reheat coils, the controller can provide active dehumidification. This means that the relative humidity in the space can be kept below an adjustable setpoint independent of outdoor weather conditions. Indoor humidity levels are recommended by ASHRAE to be kept below 60percent in order to minimize microbial growth and the life span of airborne illness causing Master Slave (Data Sharing)The controller can send or receive data (setpoint, heat/cool mode, fan request, space temperature, etc.) to and from other controllers on the communication link with or without a building automation system.This applies to applications where multiple units might share one zone sensor for both stand-alone (with communication wiring between units) and a building automation system.Water Valve OverrideThe controller can be commanded via the Rover service tool or Tracer® TU to open all hydronic valves 100 percent.This allows for the faster water balancing of each unit and the entire system when the command is sent globally to all controllers. A properly balanced system is essential for proper and efficient operation.Hydronic Coil Freeze Protection (Freeze Avoidance)Systems

81 used in cold climates need to take prec
used in cold climates need to take precaution to avoid hydronic coil freeze-up.The controller does this from three different aspects. Any of these methods of protections will result in the unit fan being disabled, the outside air damper being shut, and the hydronic valves being opened 100 percent. The three methods of freeze avoidance include: A binary freeze protection thermostat is mounted on the coil and will cause a latching diagnostic if the coil temperature falls below 35°F.Figure 30.Master slave system layout UV-PRC003Q-ENControls An analog discharge air sensor monitors the temperature of the air coming off of the coil and if the temperature falls below 40°F the outside air damper is closed, the fan is turned off and the valves are fully opened.When in the unoccupied mode, the controller has an adjustable freeze avoidance setpoint. If the outside air temperature is below the setpoint, the unit will open the valves to allow water to flow through the coils.InteroperabilityInter-operability allows the owner freedom to select multiple vendors, and multiple products.With this advantage, the owner can choose the best products, the best application, and the best service from a variety of suppliers to meet their evolving building control needs in a cost effective manner. Generic Binary Input/Output The three generic binary inputs/outputs are not part of the normal control, but are actually controlled through the Tracer® SC or Tracer Summit™ system (when present) to issue commands to the controller to turn the generic inputs/outputs of add-on equipment (such as baseboard heating, exhaust fans, occupancy sensors, lighting, etc.) on and off.This binary port is not affected when other binary diagnostics interrupt unit operation. Sequence of OperationTracer® ZN520 and UC400-BOff: Fan is off;

control valve options and mixing box damper options close. The low air temperature detection option is still active.Auto: Fan speed control in the auto setting allows the modulating control valve option and single- or three-speed fan to work cooperatively to meet precise capacity requirements, while minimizing fan speed (motor/energy/acoustics) and valve position (pump energy/chilled water reset). As the capacity requirement increases at low fan speed, the water valve opens. When the low fan speed capacity switch point is reached, the fan switches to the next higher speed and the water valve repositions to maintain an equivalent capacity. The reverse sequence takes place with a decrease in required capacity.Units with three-speed fans on low, medium, or high: The fan runs continuously at the selected speed and the valve option cycles to meet setpoint.Wireless SystemsAir-Fi® Wireless Communications Interface (WCI)A factory-installed Air-Fi® Wi(WCI) provides wireless communication between the Tracer® SC and Tracer® unit controllers. The Air-Fi® WCI is the perfect alternative to a Trane BACnet® wired communication link.

Figure 39.Low temperature detection deviceWhen the low temperature detection device senses an entering air temperature of 36°F to the hydronic coil, the normally-closed switch opens a corresponding set of binary input terminals. The fan disables, control valves open, and the fresh air damper closes.Thirty minutes after the diagnostic, Tracer® ZN520 uses an automatic reset function to attempt to reset the unit. If the diagnostic occurs again within 24hours after an automatic diagnostic reset, the unit will require a manual reset. This function attempts to resolve the infrequent nuisance alarm.The low temperature detection device is an averaging type capillary tube and will reset when it detects an entering air temperature of at least 44°F.

On units with optional electric heat, the sensor is field-mounted in the ductwork, downstream of the unit discharge.Economizer Damper ActuatorThis option is a modulating, spring-return damper actuator and is factory-wired and mounted to the mixing box damper assembly. When the controller enables the economizer damper and the unit is in occupied mode, the damper modulates between its minimum position (configurable) and the full open position to maintain setpoint temperature. If economizer operation stops or if the unit is in the heating mode, the damper adjusts to its minimum position. Trane highly recommends using the low temperature detection option with a mixing box damper to detect possible freeze conditions. Sensor for Demand-Controlled VentilationThe unit is provided with a CO sensor to enable demand-controlled ventilation (DVC). This sensor provides a 4-20mA signal and ships separate for field installation (wired to Ul1). DCV can be used for modulating ECM, single-speednctions during occupied modes (Occupied, Occupied Standby, Occupied Bypass), in either heating or cooling mode, as long as the fan is operating (high, medium, low, On, or Auto). Refer to BAS-SVX48*-EN Tracer® UC400-B Programmable Controller for Blower Coil, Fan Coil, and Unit Ventilator Installation, Operation, and Programming manual for a description of DCV control and guidance in determining the and economizer damper setpoints for a given application.
