WebMay 22, 2024 · the amount of heat the heat pump can add to a room is equal to: Qhot = COP heating x W = 3 x 1500 = 4500 W or 4500 J/s In case of the cooling mode, the heat pump (air conditioner) with 1500 W motor can take heat Qcold from inside the house and then dump Q hot = 4500 W to the hot outside. Using the first law of thermodynamics, which states: WebHeat pumps, air conditioners, and refrigerators utilize heat transfer from cold to hot. They are heat engines run backward. We say backward, rather than reverse, because except for Carnot engines, all heat engines, though they can be run backward, cannot truly be reversed.
