Propane-based heat pumps, up to 30% more efficient than R410A, have the greatest potential for quick growth in the American market, he says.
Made by ZF, the unit, filled with 290g of R290, reduces weight with twice the cooling capacity compared to previous methods for cooling and heating e-cars.
The Fraunhofer Institute for Solar Energy Systems aims to develop propane heat pumps to replace existing fossil fuel-based heating systems in a range of residential applications.
With coupling options, the new air-to-water range offers capacities from 48 to 190kW, with hot water production up to 75°C.
Each store will use two-to-five of the12kW capacity air-to-water units, which provide hot water flow temperatures up to 75°C at ambient temperatures down to -25°C.
The Fraunhofer Institute’s solar thermal façade panels offer a noiseless and space-saving alternative to the air unit of an air-source heat pump.
With the purchase of Viessmann Climate Solutions, the U.S. OEM hopes to accelerate its transformation into a global leader of ‘intelligent climate and energy transition solutions.’
Natural refrigerant-based heat pumps are on the rise in Europe, according to a new report released on April 20 by ATMOsphere, publisher of Hydrocarbons21.com. The report “Delivering Today on EU F-gas, REPowerEU and PFAS Restriction with Natural Refrigerant Heat Pumps,” was published ahead of the kick off of the European trilogue among the European Commission,…
The manufacturer’s plans include producing the indoor propane-based residential heat pump at its facility in Eibelshausen, Germany.
Slated for large-scale production in July, the new R290 units range in capacity from 4 to 16 kW, producing outlet water at 75°C.
