Classification, principle and use of refrigeration compressors

Classification, principle and use of refrigeration compressors<br></br> The function of refrigeration compressor:<br></br> The refrigeration compressor is the "heart" of the refrigeration system. It absorbs the refrigerant vapor from the evaporator, increases the pressure and discharges it to the condenser, so that the refrigerant circulates in the system. Can be used in refrigeration systems and heat pump systems

Failure analysis and analysis of other common failures of screw refrigeration compressor

The compression ratio of the screw machine is too large: it proves that this system completely deviates from the design value. The main phenomena are that the temperature of the exhaust temperature is too high, the suction pressure is too low, and the tem器2䀀
