Define heat of compression, and explain how it is computed.
Heat generated when air is compressed.
The total amount of heat energy, in Btu/h, that is generated or absorbed into the refrigeration system outside of the evaporator is the sum of the heat of compression (HOC) and the heat picked up by the refrigerant in the suction line.
The heat content at the outlet of the compressor, point E, is 136Btu/lb. Since the refrigerant entered the compressor with heat content of 113 Btu/lb, the amount of heat added to the refrigerant during the compression process is 23 Btu/lb ( 136Btu /lb) . This is referred to as heat of compression (HOC) for the compressor.
Energy from the pressurization of a gas or liquid converted to heat.
