| Abstract: | The finite time thermodynamic performance of steady flow Carnot and Brayton refrigeration cycles is studied for both finite and infinite thermal capacitance rates of heat reservoirs.The fundamental optimal relations of the two cycles are obtained. A comparion of the performance characteristics of the two cycles for the same boundary condition, i.e., the same heat source/sink inlet temperatures, thermal capacitance rates, and heat exchanger conductances,is performed. The effects of finite thermal capacitance rates of working fluid and heat reservoirs, and the internal irreversibilities of the cycles on the performance of the cycles are analysed,and the optimal matching between working fluids and variable-temperature reserviors are discussed. |
