R290, commonly known as propane, has a long history as a refrigerant and is now seeing renewed adoption in heat pump systems ...

An international research team has conducted a computational analysis on propane (R290) vapor compression heat pumps integrating a thermoelectric subcooler (TESC) to reduce the power consumption of ...

ELECTRICITY CAN be made from the sun, the wind or the atom rather than by burning fossil fuels. Cars, buses and perhaps even lorries can be powered by batteries rather than petrol or diesel. But other ...

Currently heat pump manufacturers are mainly focusing on cost reductions and sustainable refrigerants. In the project “LC150” (Low Charge 150 g), the Fraun-hofer Institute for Solar Energy Systems ISE ...

Heat pumps are a key technology in the heat transition, but many of the devices still use environmentally harmful refrigerants. The Fraunhofer Institute for Solar Energy Systems ISE has now developed ...
