Summary

The possibilities were studied, and a quantitative evaluation was undertaken, of the use of ambient air as a low-grade heat source for a heat pump running on different fluids (R22, R142 and R134a) and at different average temperatures in the heat exchanger between the cascades. A method is proposed for calculating the desired operating parameters for a two-stage heat pump and an algorithm that can be used to do this calculation with a computer. The best energy characteristics were obtained for the installation in which the low-pressure stage runs on R22 and the high-pressure stage runs on R134a. C.C.
