USA: Philip Doyle Manufacturing, a Canadian-based producer of severe duty air conditioning systems, has opted to use Honeywell’s Solstice N15 (R515B) refrigerant.
Established in 1966 and based in Ontario, Philip Doyle is a manufacturer of operator cabins, control room enclosures and industrial air conditioners.
Solstice N15 was designed as a lower GWP replacement refrigerant for R134a and R124 in chillers and heat pumps. It is an A1 non-flammable refrigerant blend with a GWP of just 293 under AR4. A blend of R1234ze (91.1%) and R227ea (8.9%), it is said to have zero glide and low discharge temperatures with an efficiency to match R134a.
Philip Doyle is said to have selected the refrigerant to meet global HFC phase down regulations and stringent customer requirements for applications including enclosed crane cabins. These heavy equipment operators toil in sweltering temperatures in enclosed crane cabins and require small-format climate control systems to stay cool.
“Our customers were seeking a refrigerant solution that is safe, suitable for temperatures that can climb up to 90ºC in crane cabins and minimises impact on the environment,” said Philip Doyle Manufacturing project manager Basil Mendonca.
“Solstice N15 was specifically innovated and brought to market with component suppliers to provide chiller and heat pump manufacturers with a long-term solution that can address any installation requirement with the same chiller design,” said Chris LaPietra, vice president and general manager, Honeywell Stationary Refrigerants.
As a non-flammable R-134a replacement, Solstice N15 is said to be able to be used immediately by chiller and heat pump manufacturers where safety standards and buildings codes limit the use of A2L and A3 refrigerants. Honeywell says its similar product design to R1234ze will provide OEMs with a long-term solution that is flexible for both A1 and A2L refrigerants.
