Honeywell backs Danfoss scrolls on R1234ze and R515B

United states: Honeywell suggests it is supporting Danfoss with the growth of a soon-to-be released variety of scroll compressors primarily based on lower GWP refrigerants R1234ze and R515B.

The DSG compressors are specifically created for medium stress chillers to awesome substantial buildings, infrastructure tasks, district cooling/heating, and other programs. With this new compressor technological know-how, the use of R1234ze and R515B will have the risk to develop into OEM’s scroll chiller platforms

Thanks to be released in the second quarter of 2022, Honeywell suggests the compressors will produce improved electrical power effectiveness about versions centered on R410A, whilst offering the exact same cooling capacity and comparable footprint.

R1234ze is a one element HFO with a GWP of 7. It is classed as A2L below the ASHRAE 34 and ISO 817 standards. R515B is predominantly R1234ze(E), with the addition of just a little sum (8.9%) of R227ea. It is an A1 (non-flammable) refrigerant with a GWP of 293.

“Danfoss’ new DSG scroll compressors signify an industry breakthrough on a quantity of fronts, and enable shoppers to fulfill the most stringent sustainability, efficiency and protection targets,” mentioned Ken West, vice president and general supervisor, Honeywell Fluorine Solutions. “Compared with R410A-based mostly remedies, the R1234ze versions tick a few significant containers wherever no other remedy exists currently: around carbon neutrality, substantial overall performance, and safety. In the meantime, the R515B designs give the only low GWP, non-flammable option to R410A perfect for indoor purposes.”
