DSH with IDV technology

High efficiency in part-load conditions

Danfoss scroll compressors feature a wide application envelope and suit such varied applications as rooftops, chillers, or process cooling systems, reducing the number of items held in reference and inventory. Danfoss DSH scroll compressors feature intermediate discharge valve (IDV) technology, extending the operating envelope even further for incredible flexibility in system designs.

Danfoss IDVs are located close to the discharge side within DSH compressors. They reduce excessive refrigerant compression under part-load conditions while maintaining the same ideal cooling capacity. IDVs open when discharge pressure falls below the built-in optimization point, adapting the effort of the motor to varying load and pressure conditions in the system. This reduces the system's electrical consumption and improves seasonal energy efficiency.
