How an Air Conditioner Works | The Refrigeration CycleThe refrigerant needs to be colder than the indoor air in order to absorb heat. Once the refrigerant gets cooled down, it flows back into the evaporator coils where it begins the refrigeration cycle again. Hopefully, this helps you understand the basic workings of an air conditioner.
Air Conditioning - Evaporator - swtcChanging the state of the refrigerant in the evaporator coils is as important as the air flow over the coils. Liquid refrigerant supplied to the coils by the expansion valve expands to a vapor as it absorbs heat from the air. Some liquid refrigerant must be supplied throughout the total length of the evaporator coils for full capacity.
