Theory of heat pumps
Webb12 sep. 2024 · A refrigerator (or heat pump) absorbs heat Q c from the cold reservoir at Kelvin temperature T c and discards heat Q h to the hot reservoir at Kelvin temperature T h while work W is done on the engine’s working substance, as shown by the arrow pointing toward the system in the figure. Webbof annual maintenance of a gas boiler – no maintenance for a heat pump – then the heat pump system is likely to have a somewhat lower running cost. (More decisively, the heat pump system has a 32% lower running cost than oil – or even lower when maintenance costs of the boiler are included.) HEAT PUMPS – The theory 2 NOVEMBER 2009.
