What is the evaporator's role in the cooling cycle?

The evaporator’s job is heat removal from indoor air by causing the refrigerant to evaporate inside the coil. As the refrigerant arrives as a low-pressure liquid, it absorbs heat from the surrounding air and boils into a low-pressure gas. That heat transfer cools the indoor air, and the resulting gas moves on to the compressor to continue the cycle. This contrasts with other parts of the system: the compressor increases refrigerant pressure, and the condenser outside rejects heat and condenses the refrigerant back to a liquid. The evaporator isn’t a storage point for refrigerant; its primary purpose is to absorb heat through the evaporating refrigerant.
