Discussion on Calculation of Cooling Coefficient in Thermal Teaching Materials

Abstract

The cooling coefficient ε of the reverse cycle is equal to the net heat Q absorbed by the system from the low temperature heat source by one cycle. The net power A of the system is calculated by subtracting the heat Q released by the system to the low temperature heat source in one cycle. The cooling coefficient ε can be greater than 1. It can also be less than 0. The cooling coefficient of the reverse cycle is less than the cooling coefficient of the Carnot cycle.
