Danfoss extends operating envelope for DSH scroll compressors
30th November 2021
DENMARK: Danfoss has qualified a larger application envelope for its DSH medium scroll compressors using lower GWP refrigerants R452B and R454B.
As the newly optimised compressors are 100% back-compatible, ordering codes will remain the same.
The maximum condensing temperature has been extended from 65℃ to 68℃. So, high side working range is now 41.7bar(g) and maximum high pressure safety switch setting is adjusted accordingly from 40.6 to 43.1 bar(g).
Due to increased compressor discharge gas temperature, a new acoustic hood has been developed for the R452B/R454B application.
