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 ...

Heat pumps use environmental energy to provide us with heat. However, they generally require synthetic refrigerants, which contain environmentally harmful fluorinated greenhouse gases (F-gases).

Propane heat pumps for indoor use in single-family homes are now one step closer to commercialization. Germany’s Fraunhofer ISE has successfully developed a model of a heat pump refrigeration circuit ...

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 ...

Last month, city officials unveiled the first electric car-charging station in Duluth. On Tuesday, Como Oil unveiled Duluth's first gas pump dedicated to propane-powered vehicles. The new propane pump ...

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 ...
