Evaporative Cooling System Sketch

Unlike central air conditioning systems that recirculate the same air evaporative coolers provide a steady stream of fresh air into the house.

Evaporative cooling uses the fact that water will absorb a relatively large amount of heat in order to evaporate. When operating an evaporative cooler windows are opened part way to allow warm indoor air to escape as it is replaced by cooled air. For more information on evaporative cooling systems and how they work please visit http cosaf co uk or http cosaf ae. An evaporative cooling system consists of an intake chamber filter s supply fan direct contact or indirect contact heat exchanger exhaust fan water sprays re circulating water pump and water sump.

Two evaporative cooling systems are commonly used in greenhouses. In general the machine will consist of a fan a thick pad a water reservoir and some additional controls for fine tuning the results. They produce cool and humid air and are. The basis of any evaporative cooling system is the evaporation of water into an airstream.

An evaporative cooling system takes basic evaporation and automates it to efficiently lower the temperature of the air in your home. The most common way of accomplishing evaporative cooling in a greenhouse is with a fan and pad system figure 1. Note that swamp coolers can be considered stand alone evaporative cooling systems but otherwise operate similarly as pad and fan systems. Evaporative cooling differs from typical air conditioning systems which use vapor compression or absorption refrigeration cycles.

The fan draws dry hot air into the machine and across the cooler pads these thick pads absorb water from the reservoir and. Evaporative coolers cost about one half as much to install as central air conditioners and use about one quarter as. Pad and fan systems are part of a greenhouse s mechanical ventilation system. An evaporative cooler also swamp cooler swamp box desert cooler and wet air cooler is a device that cools air through the evaporation of water.
