Page 5: Features
Organ pipe master oil circulation in manifold configuration. DSF090-200 How do IDVs work? 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. -
