Adiabatic air cooling additive systems
1Slide2
Typical areas we serve:
Air cooled chillers RefrigerationDry Coolers Air intake
Unitary
2Slide3
Typical problems we solve:
Increase in the electricity billPartition close to the equipment or installation of new equipment around the existing units leading to air recirculation and poor unit operationUnits located in places with higher air temperatures
Equipment fitted with high pressure refrigerant suffering ambient air limitations
Reduction of the available power supply
Additional cooling capacity required
3Slide4
How is solved:
Reduces condensing air temperature inlet due to:Air recirculation Summer peak temperatures
Avoids high pressure cut-outs
The compressors
operates in better conditions and its life cycle is increased:
Lower discharge temperature
Lower oil temperature
Lower winding temperature
4Slide5
Efficiency:
Reduction in the unit’s power consumptionMaintain equipment at
full+ load during
peak
season
Improved cooling capacity
Benefits:
Shading effect
The mesh placed in front of the coils
shades and overcomes
the solar radiation effect on coils, resulting in an additional 2°C to 3°C temperature drop
.
Self-cleaning filter
The mesh also acts as a self-cleaning filter keeping the coils clean longer and protecting them
against dust and etc.
5Slide6
Adiabatic cooling uses the thermo dynamic properties
of water and its evaporative cooling effect.
Concept
is based on intermittently and efficiently evaporating water on a large mesh
on the way of air stream.
The evaporating water makes the air temperature drop before it reaches the condenser
.
The water
spraying
towards
the mesh, evaporates on the mesh and does not reach the coil.

Standard maintenance schedule:3M
Check
for any scale or dirt / debris build up on mesh. Remove in accordance with
manufacturers
recommendations.
Check
for any leak in pipe work or nozzle heads.
Check
spurge system for correct operation in particular the solenoid valve operation. If
faulty
replace the solenoid valve.
Check
spurge controller for correct settings.
Adjust if necessary.
6M
(Winter isolation if applicable)
Drain
the pipe work and isolate both the water circuit and the controller
.
Check the mesh tensions and leave them in-situ.
Clean
meshes if there is any debris / dirt.
6M
(Summer activation if
applicable)
Open
main water valve and activate
the controller
.
Test
the spray operation and mesh wetting patterns. If any of the nozzles blocked clean
them
.
Clean
meshes.Slide12
