MFI Series | Operation: Performance |
Beginning at the compressor, the refrigerant is compressed into a high temperature gas. The discharge line directs this gas to the condenser. At the condenser (air or water cooled) the gas is cooled by either air or water and then it condenses into a liquid.
This high pressure liquid then goes through the liquid line to the expansion valve. The thermostatic expansion valve meters liquid refrigerant into the evaporator, the volume of liquid refrigerant depending upon the temperature of the evaporator.
At the evaporator, the refrigerant enters an area of relatively low pressure, where it can easily “boil off” or evaporate. As it evaporates, it absorbs heat from the evaporator and whatever is in contact with it (such as water inside it). After the evaporator, the refrigerant, now a low pressure vapor, goes through the suction line back to the compressor, where the cycle is repeated.
