Proposed the concept of “dual source (double channel)”, analyzed the feasibility of dual source heat exchanger, and designed a double-channel ribbed double-channel heat exchanger. The heat exchanger Of the processing technology, performance parameters, the maximum efficiency of the composite heat transfer temperature and heat transfer efficiency, to achieve a dual source dual road in the composite utilization. The heat transfer efficiency of the dual-source heat pump unit under various working conditions and different operation modes is studied experimentally. Through the analysis of effective experimental data, it is concluded that within the effective temperature range, the new ribbed dual-source Heat exchanger efficiency of up to 85%.
