A reduction of residential buildings’ energy consumption and the electrification of heating are clear objectives of European energy policies.
Heat Pump technology is recognized as one of the main possible replacement for fossil fuel boilers and, due to higher energy efficiency and the use of electricity, can be key to reduce primary energy consumption and to enhance the electrification process. The most common refrigerant employed in Heat Pumps in the past decade has been R-410A. The use of this HFC refrigerant with global warming potential (GWP) of 2088 will be progressively limited to comply with the F-Gas Regulation EU No 517/2014 and Low GWP alternatives, such as HFO blends refrigerants, will be increasingly adop ...
