Cold climate air-source heat pump


Technology Description

Heat pumps whose seasonal performance factor remains above 2.5-3 while operating several days in the year at temperatures lower than -10 °C, and which could withstand -25 °C. Cold-climate heat pumps minimise losses of heating capacity as outdoor temperatures drop through the adoption of two new scroll compressors working in parallel and/or adoption of a mix of refrigerants with thermophysical properties.

Relevance for Net Zero

Cold climate heat pumps are an alternative to fossil-fuel boilers in areas of low or medium density, bringing significant energy saving opportunities and the possibility to phase out coal, oil and gas use in buildings.
