About the role of screw air compressor inverse proportional valve

The inverse ratio valve is used in conjunction with the disc air intake control. When the system pressure increases due to the decrease in air consumption and reaches the set pressure of the inverse ratio valve, the inverse ratio valve acts and reduces the control air output.

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
