Rheem’s new air-source warmth pump has handed the US Division of Power’s Chilly Local weather Warmth Pump Problem. The US-based heating specialist launched the Endeavor Status sequence in March. It’s reported to have a heating efficiency issue (HSPF2) of as much as 8.5 and a coefficient of efficiency (COP) of between 1.5 and a pair of.0 at -8 C.
“We’re not stunned that our staff of devoted, progressive engineers at Rheem has developed a residential warmth pump that delivers 77% of nominal heating capability at −26 C ambient temperature and offers uninterrupted heating that operation at −30.5 C ambient temperature exceeds expectations and delivers the very best high quality efficiency,” stated Jeff Goss, director of product administration for Rheem.
The brand new cool local weather warmth pump is reported to offer 5% larger COP throughout heating beneath -15 C ambient temperature than the problem specification. Rheem says the unit additionally performs a 9% larger HSPF2 than the problem specification.
The Endeavor Status warmth pump has a heating capability between 7.03 kW and 17.58 kW. The smallest mannequin measures 1,147 mm x 918 mm x 918 mm, whereas the most important measures 1,300 mm x 918 mm x 918 mm x 918 mm. It makes use of R-410a as refrigerant and operates at 59 dBA to 73 dBA.
US-based Provider and Johnson Controls, in addition to Eire-based Trane Applied sciences, have additionally developed prototypes for the sector check part of the Chilly Local weather Warmth Pump Problem. Lennox was the primary producer to efficiently construct a prototype, profitable the Chilly Local weather Warmth Pump Problem in June 2022.
