WebMay 22, 2024 · 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: Qcold + W = Qhot, we obtain the heat, Qcold = 3000 W. From the definition: COPcooling = 3000/1500 = 2.
WebA device such as a refrigerator or air conditioner, designed to remove heat from a cold region and transfer it to a hot region, is essentially a heat engine operating in reverse, as the following energy flow diagram shows: A refrigerator, consisting of a fluid pumped through a closed system, involves a four-step process.
