The Refrigerant Cycle how it works in simple form...
Without going into the various properties of refrigerants lets just say the refrigerant is much like water.It boils and turns into a vapor (steam) and cools back down and condenses back to a liquid (water) and in this process of changing state from liquid to vapor all liquids absorb a bunch of heat. Heat can only travel one way, from hot to cold, you cannot "cool" anything only remove it's heat.
Refrigerant Cycle
In the diagram starting at the compressor the refrigerant is increased in pressure which also increases it's temperature as part of the nature of refrigerant. The refrigerant passes through the condenser coil and the heat is transferred to the medium, in this case air utilizing a fan (outdoor air conditioning unit or condenser).The refrigerant is changed from a gas or vapor into a high pressure liquid by removing the heat, same as if you cooled steam it changes back to water. This liquid is then metered or the amount of refrigerant is regulated to a small amount directly into the evaporator coil.
As the refrigerant absorbs heat from the air flowing through the coil it changes back into a gas or vapor just as if you heated that water back up to make steam. Remember that when it changes state from a liquid to a vapor it absorbs a whole bunch of heat just like water. The gas or vapor refrigerant is then returned back the compressor to be pressurized all over again.
