Agent flows through compressor suction, the loss of air bleeding valve；Second aspect is loss caused by energy conversion:Compressor first converts electric energy to
Mechanical energy, then thermal energy is converted mechanical energy into, there are greater loss for conversion twice.The third aspect is compressor suction, air bleeding valve valve
Mouth is too small and compressor inside complicated structure barrier evaporator is connected with condenser and caused damages：1, due to compressor air suction valve
Valve port is too small so that the evaporator outlet being mated with is too small, and refrigerant liquid is too small in the Free Surface of evaporator, so as to press down
The generation of refrigerant liquid evaporation conditions processed.It is even more impossible to make full use of the heat of cooled medium that refrigerant liquid heat absorption is promoted to steam
Hair vaporization；2, since the too small condenser inlet for be mated with of compressor exhaust valve valve port is too small, cause entry into condenser
Refrigerant vapour flow resistance it is too big；3, since complicated structure barrier evaporator is connected with condenser inside compressor, evaporate
The refrigerant vapour of device outlet can not be done irregular heat movement by gas molecule and reach condenser.Other aspects, practical pressure
Contracting machine motor power factor is less than 100%, and there are feeder ear losses.So it is adopted for manufacture high-temperature high-pressure refrigerant steam heat source
With mechanical compression mode, compressor can be made to do a large amount of idle work, and can not fully promote using the heat of cooled medium
Refrigerant liquid heat absorption carburation by evaporation inside evaporator, causes steam compressed refrigerating circulating system efficiency low, causes steam
Compression-type refrigeration circulator high energy consumption.
