In this study. optimum allocation of heat transfer inventory for heat exchangers in a refrigeration system with specified power input or cooling capacity. and for a heat pump with specified heating capacity is investigated. The ratio of hot- to cold-end conductance unit cost ratio. G.was considered in the analysis as an additional variable of considerable importance to the designer Summarized equations are given in terms of unit cost of conductances of both the heat exchangers .the results show a strong dependence of the total cost on the absolute temperature ratios as well as the hot-to the cold-end conductance cost ratio. It has been demonstrated in the given example that for G=0.1. The conductance of the hot-end heat exchanger is about three times the cold-end heat exchanger.
