Honeywell

Honeywell’s Solstice® Refrigerants represent a unique concept bridging the regulations on F Gases with the efficiency of HFCs enabling the industry to utilise existing equipment and reduce carbon footprint. They are positioned to help the refrigeration and AC industry meet the F-Gas phase down. Solstice HFO molecules (Solstice® yf, Solstice® ze and Solstice® zd) can also form the basis for future low GWP blends for various application segments, like Solstice N13, Solstice N40, Solstice L40X, Solstice L41y, Solstice L20, as replacement for R22, etc.. The Solstice family will help the refrigeration and AC industry meet the challenging objectives of emissions reductions now and in the future all around the globe.

Solstice L40X is a (developmental) blend of 75.5% Solstice yf, 21.5% R32 and 3% CO2. Its planned use is in condensing units where R-404A is currently used, as well as other small hermetically sealed equipment. It matches the capacity of R-404A and has the same or better efficiency relative to R-404A, with GWP of only a fraction of R-404A: 145. Discharge temperature within compressor R-404A limits in LT applications and is safer to handle than propane and other A3 and A2 class refrigerants.

Solstice® yf is one of the most environmentally benign refrigerants and specifically tailored for the automotive industry for use as a refrigerant in car air conditioning systems. With a GWP<1, a fraction of the global warming impact of traditional automotive refrigerants, it provides the same cooling comfort that consumers depend on and surpasses new EU standards. Honeywell is building capacity to make sure that future supply security is guaranteed.

As R123 is banned, Solstice zd, with similar characteristics and a GWP=1 is expected to revive low pressure centrifugal chillers, known for their high capacity and efficiencies. In addition Solstice zd shows great potential in high temperature heat pumps. Major chillers manufacturers have already announced product ranges based on Solstice zd

Solstice® ze Refrigerant for chillers, heat pumps, district cooling & heating, plug-in units, ORC, etc. is the best energy-efficient alternative to systems where 134a is currently used,.. With a GWP <1, that represents a 99.9% reduction in direct impact versus the current refrigerant, it also meets the rest of criteria that are most important to refrigerants customers: Performance, Cost Effectiveness and Safety. Major chillers and heat pumps manufacturers have already announced product ranges based on Solstice ze.
