The Robur RTAR is a modular, reversible cycle gas absorption heat pump system capable of producing hot water up to 140°F and chilled water down to 41°F. Under nominal conditions, each heat pump module ...

This generation of heaters and chiller-heater gas-fired absorption heat pumps provides cooling and/or heating from a single unit operating on natural or propane gas. Minimal electricity is required by ...

The proposed system uses waste heat by thermally coupling a water lithium bromide absorption heat transformer with a water vapor compression heat pump. It reportedly achieved a temperature elevation ...

German manufacturer Viessmann says its new heat pumps have a coefficient of performance (COP) of up to 4.57 and a seasonal coefficient of performance (SCOP) of up to 4.4. The pumps have a heating ...
