Description:

The basic conceptualization of a heat pump can be understood as a machine or device that delivers heat from one area which is at a lower temperature to another are which is at a higher temperature by using mechanical work or a high-temperature heat source. Thus a heat pump may be transformed as a "heater" if the motive is to warm the heat sink, or as a "refrigerator" if the motive is to cool the heat source. Hence heat pumps make a valuable contribution to energy conservation by utilizing the self generated energy to the fullest because in either case, the operating principles are identical. Heat is moved from a cold place to a warm place or vice-versa. Heat pumps operate on the vapour compression cycle using a refrigerant as the working fluid as a medium to transfer heat.
