During Australia’s hottest months Industrial, Commercial and even Domestic HVAC units struggle to cope due to increased head pressures caused by high ambient temperatures.
When air temperatures rise to over 50 degrees Celsius the efficiency of standard condenser coil units drops dramatically from the design set point of only 46 degrees. Units that reach these temperatures are under threat of shutting down and costing businesses thousands of dollars.
A correctly installed pre cooling system can save you up to 30% on your building air conditioning, refrigeration energy and running costs.
HOW DOES IT WORK?
The Evaporation” technology is used to pre cool the air around the condenser units.
Cool air is drawn in over the coil, thus resulting in lower head pressures and compression ratios. Unlike traditional “sprinkler setups” used on some systems to wet the condenser units in summer, the CoolairAustralia’s evaporation systems HVAC solutions leave minimal moisture contact with the coil, and will only run when required thus reducing water wastage and excess water sitting on the coils because of regulation of humidity.
Evaporation technology Pre Cooling Facts:
- Reduction in temperature of approx 10 to 15 degrees Celsius at the coil face.
- Energy reduction drops, saving as much as 30%.
- Increases the efficiency of air-conditioning units by as much as 30%
- Improves the capacity of under performing refrigeration data center and HVAC units under high ambient conditions.
- Reduces system downtime.
- Improves occupant comfort level.
- Environmental benefits – lower kW consumption reduces your carbon footprint.
- Reduction in water usage when compared to traditional cooling methods.
- Can be retrofitted to existing condensers without disruption to the Refrigeration, Data Center or HVAC system.
An independent study conducted also found that by pre-cooling could increase the co-efficient performance by up to 30%, and also generate significant energy savings by using mist to pre-cool the ambient air temperature.@
