The Refrigeration cycle operates as follows:
First, cool, low-pressure, gaseous refrigerant enters the compressor. Hot, high-pressure gaseous refrigerant exits the compressors and moves to the condenser. Once there, the hot refrigerant releases heat outside the system. The hot, high-pressure liquid then leaves the condenser coil and enters the expansion valve, which reduces the pressure and temperature of the refrigerant. The cold (low-pressure) refrigerant absorbs inside heat to cool the system environment, and refrigerant leaves the condenser as a cool, low-pressure gas. The cycle repeats.
Refrigeration superheat is the difference in refrigerant temperature at the evaporator outlet and the boiling temperature of the refrigerant at a measured pressure. By monitoring the temperature and pressure of the refrigerant with pressure transducers as it leaves the evaporator and as it enters the compressor, the superheat can be calculated and the expansion valve can be made to increase or decrease the amount of refrigerant used to minimize the superheat and increase refrigeration efficiency.
