Scroll compressors PSH052 to PSH105 | Introduction
Danfoss Intermediate Discharge Valves (IDVs) are located close to the discharge side of the compressor. They reduce
excessive compression of refrigerant under part-load conditions while maintaining the same cooling capacity. The
IDVs open when discharge pressure falls below the built-in optimization point. They adapt the e ort of the motor to
the varying load and pressure conditions in the system, thus reducing the e ort of the motor and its electrical
consumption and improving the system's seasonal energy e ciency.
