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.
The Midea brands have greatly reduced the amount of propane refrigerant in compressors.
These units are designed for small and medium enterprises with cold storage needs.
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 0.4kW (0.1TR) Masterflux-branded compressor is designed for EV mobile cooling and refrigerated delivery.
The air-cooled iARIES N Inverter liquid chiller has a nominal cooling capacity of 177–334kW (50–95TR).
The compressors offer best-in-class efficiency with A++ performance at 55°C (131°F).
