Webone end, is the metering device (expansion valve) which controls the refrigerant flow and on the other end is the compressor. The vapor-compression refrigeration system uses a circulating liquid refrigerant as the medium which absorbs and removes heat from the low side and subsequently rejects that heat in the high side. WebSep 15, 2024 · The Evaporator. The evaporator does the exact opposite of the condenser. Instead of turning the refrigerant from gas to liquid, it turns the refrigerant from liquid to gas (thus the name “evaporator”). Instead of expelling heat, it absorbs heat and turns the air cold around it. This is where the “conditioning” of the air occurs. drew barrymore 2011
