Heat pump that saves electricity bills This completes a refrigeration cycle. The performance of the heat pump is generally evaluated by the cooling coefficient (COP coefficient of performance). The cooling coefficient is defined as the ratio of the heat transferred from a low temperature object to a high temperature object to the required power. Usually the cooling coefficient of the heat pump is about 3-4, that is to say, the heat pump can transfer 3 to 4 times the heat energy from the low temperature object to the high temperature object.
