How Does An Air Conditioner Work?


The air conditioner has been one of the most useful machines ever invented especially since it has been designed to provide comfort whenever the surrounding temperature gets too hot for us.

 It wouldn’t hurt to know how this piece of appliance works would it? Let this article be an attempt to briefly explain the basics of air conditioning, just so you’ll have an idea.

 Much like the reliable refrigerator we have in the kitchen, the air conditioner has three main parts: the compressor, the condenser, and the evaporator, These three work in unison with other essential parts like the refrigerant or Freon, fans, metal fins and thermostat.

 Air conditioners are simply based on the concept that in the process of evaporation, heat is absorbed.  The process starts with the refrigerant, the cool substance in gaseous form, entering the compressor.


 Compressor subjects this gas to heavy compressing making the gas increase its temperature and pressure. This hot gas then moves through a set of coil where the heat is dispersed, eventually becoming a condensed liquid.

 This condensed liquid is forced through very fine metal fins in a valve where it comes out as cold mist. This then travels through another set of coil where it evaporates. With the evaporation, heat in the area is absorbed and the fans blow the cold mist to the room.

 The gas that has extracted the heat goes back to the compressor and begins the same process again and again until the machine detects that the room has already reached the desired thermostat. At this point the compressor shuts off but gets kicked to start when the room starts to heat up again.
