PERFORMANCE ANALYSIS OF SOLAR THREE-HEAT-RESERVOIR COOLING SYSTEMS

摘要

The optimum performance of a solar three-heat-reservoir cooling system, which consists of a solar collector and a three-heat-reservoir cooler, was studied. The analysis is based on the linear (conventional and/or conductive) and radiative heat transfer models of solar collectors and the general optimum characteristics of endoreversible three-heat-reservoir coolers with Newton's and linear phe-nomenological heat transfer laws between the working fluid and the reservoirs of the coolers. The overall coefficient of performance (COP) of the system is adopted as the objective function of the performance analysis. The optimum operating temperatures of the collectors at the system maximum possible COP or at the system maximum possible cooling load are carried out. The results provide the basis for designing a real solar three-heat-reservoir cooling system.
