Vapor compression heat pump for drying room.A conventional technique to upgrade low temperature heat to a.Higher temperature level is heat pump system. The common method.Could be performed by vapor compression heat pump (VCHP which.)The main components are compressor condenser evaporator and,,,Expansion valve as shown in Figure 6. The working fluid has a low.Boiling temperature. At, state 1 the fluid in vapor phase is compressed.In the compressor to state 2 and the vapor condenses in the condenser at.A high pressure and temperature to be liquid at state 3. The liquid is then.Throttled to a low pressure at state 4 via the expansion device and the.Temperature drops down thus the fluid could absorb low temperature.Heat at the evaporator where the fluid boils at low temperature to be.Vapor again and the new cycle restarts.
