It called on manufacturers to commercialize equipment that can heat up to 200°C to reduce its reliance on fossil fuels.
Certified data on two comparable A+++ units found the natural refrigerant model to be 21-34% more efficient than the f-gas option.
The three companies purchased (Emicon, Hidros and Ethra) focus on natural refrigerant commercial heat pumps and chillers.
ATMO Europe: European Commission Report Promotes Natural Refrigerants as Competitive Edge for EU Heat Pump Manufacturers
The European Commission’s energy department premiered the report at ATMO Europe.
The Midea brands have greatly reduced the amount of propane refrigerant in compressors.
A switch from R32 to R290 would likely incur a small incremental material cost (less than €10).
The heat pump generated 12.8kW (3.6TR) of heating capacity with only 124g (4.4oz) of R290.
The heat pump is expected in 2023 while the low-charge chiller for indoor installation will soon be commercially available.
The L Series home heat pumps will deliver hot water up to 75C, suitable for older radiators.
Manufacturers would have time to scale up the production of natural refrigerant equipment, says the European Commission.
