Scroll Compressors Support R454B, R452B Refrigerants
The line of DSH scroll compressors from Danfoss has been qualified for use with R454B and R452B refrigerants, providing OEMs an alternative to R410A. The option to use lower-GWP refrigerants was prompted by the European Union’s ongoing phase-down of high GWP refrigerants, limiting availability and increasing the price of R410A.
The Danfoss scroll compressors use intermediate discharge valve (IDV) technology to enhance seasonal part-load cooling efficiency. The compressors’ multi-refrigerant compatibility is intended to ease the refrigerant transition for OEMs.
R454B and R452B refrigerants are classified as A2L (mildly flammable) and are regulated under EN378 and IEC60335-2-40.
