Other AbstractA mathematical model was established for the double absorption heat transformer(DAHT)with wider range in which the system can maintain high thermodynamic performance.With engineering equation solver(EES),the influence of solution heat exchangers on the coefficient of performance,second law efficiency,total heat transfer area and the technical economy of DAHT system was investigated.Results show that the solution heat exchangers have significant impact on the DAHT system performance;compared with the solution heat exchanger between the generator and absorber/evaporator,the impact of the one that between the generator and absorber is more prominent.As the effectiveness of the solution heat exchangers increases,the coefficient of performance and second law efficiency of the DAHT system increase,but the system total heat transfer area first decreases and then increases.Taking technical economy into account,the solution heat exchangers should be optimized according to the specific working conditions in the design of the DAHT system.
