Evaporative Cooling System Sketch

Evaporative cooling differs from typical air conditioning systems which use vapor compression or absorption refrigeration cycles.

Evaporative cooling system sketch. Two evaporative cooling systems are commonly used in greenhouses. The coolest area of the greenhouse is adjacent to the evaporative cooling pads. 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.

They produce cool and humid air and are. Note that swamp coolers can be considered stand alone evaporative cooling systems but otherwise operate similarly as pad and fan systems. 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. When operating an evaporative cooler windows are opened part way to allow warm indoor air to escape as it is replaced by cooled air.

Evaporative cooling systems are characterised by low energy use compared with refrigeration cooling. The fan draws dry hot air into the machine and across the cooler pads these thick pads absorb water from the reservoir and. Evaporative cooling uses the fact that water will absorb a relatively large amount of heat in order to evaporate. Typical fan and pad greenhouse arrangement.

An evaporative cooling system takes basic evaporation and automates it to efficiently lower the temperature of the air in your home. Unlike central air conditioning systems that recirculate the same air evaporative coolers provide a steady stream of fresh air into the house. 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. In general the machine will consist of a fan a thick pad a water reservoir and some additional controls for fine tuning the results.
