How do IDVs work?
Figure 3: Intermediate Discharge Valve (IDV)
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.
