WebThe refrigerant comes into the compressor as a low-pressure gas, it is compressed and then moves out of the compressor as a high-pressure gas. The gas then flows to the condenser. Here the gas condenses to a liquid, and gives off its heat to the outside air. The liquid then moves to the expansion valve under high pressure. WebThe heat pump cycle and refrigeration cycle are illustrated in Figs. 5 and 6, respectively. In Fig. 5, ambient air is applied as the heat sink at T L. The thermal energy at T M is upgraded to T H by the exothermic reaction when hydrogen is transferred between a coupled heat exchanger system. The cyclic direction is anticlockwise in the heat ...

WebA refrigerator or a heat pump that operates on the reversed Carnot cycle is called a Carnot refrigerator or a Carnot heat pump. The coefficient of performance (COP) of reversible or irreversible refrigerator or heat pump is given by COP R = 1/ ( (Q H /Q L )-1) COP HP = 1/ (1- (Q L /Q H )) where Q H = the amount of heat rejected to the WebTechnically a refrigerator cycle is also a heat pump cycle. A heat pump is when heat is removed from a low-temperature space or source and rejected to a high-temperature sink with the help of external mechanical work. The inverse of the heat pump cycle is the thermodynamic power cycle.
