Honeywell recently announced its Solstice technology is supporting a new range of ultra-low global warming potential (GWP) scroll compressors designed and manufactured by Danfoss for heating and cooling applications. The new compressors deliver improves energy efficiency over models based on R-410A, while offering the same cooling capacity and similar footprint.
Danfoss will use Honeywell’s Solstice® ze (R-1234ze) and Solstice refrigerant® N15 (R-515B) refrigerants in its new DSG scroll compressor range for chiller and heat pumps used in commercial buildings, industrial processes, data centres and district heating/cooling applications. The compressor range will be available in Q2 2022 and will allow chiller and heat pump manufacturers to stay compliant with regulations requiring the phasedown of higher-GWP hydrofluorocarbons (HFCs).
With a GWP of less than 1, Solstice ze is 99.9% lower than R-410A and other HFCs. Solstice N15 (R-515B), a non-flammable, low-GWP solution, has a GWP lower than 300 and provides higher energy efficiency in the DSG compressor range than the R-410A models. Both refrigerants are based on Honeywell’s hydrofluoroolefin (HFO) technology.
The DSG compressors are specifically designed for medium pressure chillers to cool large buildings, infrastructure projects, district cooling/heating and other applications. With this new compressor technology, the use of R-1234ze and R-515B will have the possibility to expand into OEM’s scroll chiller platforms.
