Compressor Refrigeration Capacity

The compressor refrigeration capacity is calculated by the enthalpy difference between the evaporator inlet and the compressor inlet. For a specific evaporation pressure, the enthalpy at the evaporator inlet is determined by the sub-cooling temperature and the enthalpy at the compressor inlet by the suction gas temperature.

Heating capacity:

The heating capacity is calculated by the enthalpy difference between the compressor outlet and the condenser outlet ( incl. of any subcooling).

Evaporator Refrigeration Capacity

The evaporator refrigeration capacity is calculated by the enthalpy difference between the evaporator inlet and outlet. For a specific evaporation pressure, the enthalpy at the evaporator inlet is determined by the sub-cooling temperature and the enthalpy at the evaporator outlet by the evaporator temperature plus the respective superheating.

The stated value of the discharge end temperature is a mere calculated value. Additional cooling and heat dissipation are not considered. Deviations (particularly in deep freezing applications) from the real measured discharge temperature during operation are possible.
