Cycle Analysis of Heating and Refrigeration in New Air-source Heat Pump
An air source heat pump operating in cascade cycle way was presented. The new-type heat pump can operate not only in a single-stage cycle
but also in a cascade cycle. The operation performance of the heat pump was stimulated. The results indicate that
in the extremely cold conditions
the heat pump obtains large heating
high COP
small compression ratio
and low discharge temperature. For heating
the heat pump operates in conditions of optimal control to maximize energy-saving. It provides a favorable approach for extending the applicable range of the heat pump and conserving energy in cold regions.
