Precooling

The HVAC (Heating, Ventilation and Air conditioning) is the technology installed to provide indoor thermal comfort and acceptable indoor air quality.

 

HVAC is important in the design of medium to large industrial and office buildings such as skyscrapers, onboard vessels, and in marine environments such as aquariums, where safe and healthy building conditions are regulated with respect to temperature and humidity, using fresh air from outdoors.

 

Air conditioning systems perform at their worst in hot summer days, just when they are needed the most. The cooling capacity decreases by 14-15% and the power draw increases by 31%.The problem occurs in condensers which has to change vapors refrigerant into liquid forcing the air through the unit and absorbing heat from the refrigerant causing it to condense.

 

Applying water fogging system to air-cooled chillers can improve the efficiency under most of the working conditions, as the water mist could lower the air temperature entering the condenser.

 

Benefits using misting system as pre cooling systems for HVAC

• Air temperature outside the unit lowered by up to 12°C
• Energy consumption decreased, as much as 30%
• Increase the efficiency of HVAC units up to 30%
• Live of the whole system extended
• Low start up and operating costs
• Quick installation
