Improved Smart Circuitry –

By maximizing the coil efficiency and reduces flash gas wastage thus increasing the capacity by 5~8%

Energy Efficiency Fan

Lower Energy consumption on the fan motor by using a highly efficiency fan motor

Energy Efficiency Defrost Heater

a.

By reducing the mass of coil for a given capacity by 15% to 19% for various coil configurations.

b.

Use imbedded heaters fitted in the

centre

of the coil to reduce significantly waste heat being reflected into the cold room.

c.

This saves energy by reducing the pull down recovery time required to reach temperature after defrost.Slide6

Optional EC Fan Motor Benefits

Improved motor efficiency can be achieved by using optional EC motors for condensers and evaporators

A typical AC motor consumes 1.9kW at a duty of 17,000 m3/hr. Using an EC motor at the same duty point, we would only consume 1.6kW

a saving of 300 W or 18.8%

At lower speeds, e.g. for condenser applications EC motors save even more energy.Slide7

Adiabatic Condenser Pre-Cooling

Refrigeration equipment is designed to cope with the highest ambient conditions

Where water is freely available from a large roof area, Adiabatic pre-cooling is a cost effective method of lowering running costs of refrigeration equipment

By adding a dry spray system to cool the entering condenser air by 15oC,summer compressor input energy costs can be reduced by over 20% with no additional losses to the air flow experienced by other pad type pre-cooling systemsSlide8

Adiabatic Condenser Pre-Cooling

An Adiabatic pre-cooling system provides atomized water droplets that are extremely small and vaporize almost immediately, leaving no water residue on adjacent roofs paths or on condenser fin surfaces

Adiabatic pre-cooling systems provide almost free cooling benefits as water harvested from the roof of a property costs almost nil and only requires a modest initial investment and ongoing running costs vs the real economic benefits gainedSlide9

Electronic Expansion Valves

EXV technology enables energy savings due to improved efficiency of the refrigeration cycle. The possibility to operate at low condensing pressures, coupled with precise superheat control allows considerable energy savings

Field testing and case studies have proven short investment ROI payback times compared to traditional TXV systems. This is true for both refrigeration and air-conditioning applications Slide10

Variable Speed Drive Compressors

Refrigeration systems are designed for full-load conditions. Most of the time, however, their loads are average, not peak, requiring only partial capacity

Frequently starting and stopping compressors at full speed adds wear and tear to systems, and eliminates opportunities for reducing energy costs. VSDs can help in both of these areas with soft start and speed control

Raising suction pressures and therefore efficiencies can be achieved by slowing down the compressor in low load periods via a VSDSlide11

Glycol Defrost &

Underslab

Heating SystemsDefrosting LT evaporators can use up to 50% of their running costs. Glycol defrosting uses the free heat absorbed from the discharge gas of the compressor to heat a glycol solution to defrost the coil block via a secondary dedicated circuit. It also releases less heat and moisture into the refrigerated space than other defrosting methodsIn freezer rooms, associated warm glycol underfloor slab heating can also be used instead of electric heating elements. Electric systems require approximately 15 watts/m2 of electrical energy which on a large scale project can add up to thousands of dollars per year in extra running costsSlide12

Heat Exchanger

Subcooling

Suction accumulators fitted with heat exchangers improve system efficiency or COP by 4%-6% by adding extra

subcooling to the liquid refrigerant. This improves liquid quality to the expansion device, especially important in high gravity lift or long pipe run applicationsThe accumulator meters in a controlled fashion any liquid in the suction line. Heat from the warm liquid line also assists in boiling off any liquid refrigerant in the accumulator protecting the compressor from liquid slugging damage Slide13
