How does Air Conditioning work?
Modified on: Thu, 6 Jun, 2019 at 12:26 PM
There are many different types of Air Conditioning systems. Below will explain how Portable Air Conditioners work.
Air Conditioning cools the air that is already in the room.
It does not create "NEW" air.
It does not introduce any chemicals, solvents or the like into the air.
The Portable Air Conditioning unit contains 2 fans:
- The Exhaust fan takes air from the room and blows it though a HOT coil (Like a car radiator), this air is then exhausted though the exhaust hose and outside though an opening such as a window.
- The Re-circulation fan takes air from the same room and blows it though a COLD coil, this turns the air cold and blows it onto the room. The cold air then returns back to the Air Conditioner and it keeps circulating until the room reaches the required temperature, at this point the Air Conditioner stops cooling but continues to circulate the air.
The Portable Air Conditioning unit contains 2 coils:
The coils are like car radiators, they contain a refrigerant gas that is either super heater or super cooled.
The Compressor is a pump that pumps the gas around the system and into the coils.
The expansion valve changes the state of the gas, this is what causes the temperature change.
