AC Pre-Cooling with Misting

AC Pre-Cooling with Misting

Air conditioning systems often face challenges during hot summer days when they are in high demand. The cooling capacity decreases by 14-15% and the power draw increases by 31%. The root of the problem is in the condenser, where refrigerant vapors must be transformed into liquid and air forced through the unit to absorb heat and condense it.

Fortunately, the use of water fogging systems can significantly improve the efficiency of air-cooled chillers under most operating conditions. By lowering the air temperature entering the condenser with a mist of water, these systems can greatly enhance the performance of air conditioning units.

Research has shown that a reduction in condenser air temperature of 6°C can result in a 14% improvement in efficiency for typical air-cooled chillers. This number increases to a 25-30% improvement with a 12°C reduction in condenser air temperature. Implementing a water fogging system for pre-cooling can provide significant benefits in terms of energy efficiency and cost savings, especially during peak demand times.

In conclusion, incorporating a pre-cooling system into your air conditioning system can have a significant impact on performance, efficiency, cost savings, and environmental impact. Consider the benefits of water fogging systems for your next air conditioning upgrade
