| Abstract: | On the basis of an endoreversible absorption refrigeration cycle model with Newton's heat transfer law, an irreversible four-heat-reservoir cycle model is developed by taking account of the heat leakage and heat resistance losses. The fundamental optimal relation between the coefficient of performance (COP) and the cooling load, the maximum COP and the corresponding cooling load, as well as the maximum cooling load and the corresponding COP of the cycle coupled to constant-temperature heat reservoirs are derived using finite-time thermodynamics. The optimal distribution relation of the heat-transfer surface areas is obtained. The effects of the cycle parameters on the COP and the cooling load of are studied by detailed numerical results. |
