WebIn the refrigeration system’s condenser, conversion of vapor to liquid involves removing heat from the refrigerant at its saturation condensing temperature. Any additional temperature decrease is called subcooling. Finding liquid line subcooling requires two temperatures – the condensing temperature at a given At the start of the thermodynamic cycle the refrigerant enters the compressor as a low pressure and low temperature vapor. Then the pressure is increased and the refrigerant leaves as a higher temperature and higher pressure superheated gas. See more Thermodynamic heat pump cycles or refrigeration cycles are the conceptual and mathematical models for heat pump, air conditioning and refrigeration systems. A heat pump is a mechanical system that allows for the … See more The merit of a refrigerator or heat pump is given by a parameter called the coefficient of performance (COP).
