Abstract

Based on the full operating condition model of the ejector, constructs a simulation model of a solar ejector refrigeration system. The change of solar radiation not only cause temperature deviation but also affect condensing and evaporating temperature. Assuming that the inlet parameters of the water on the heat exchange side of the evaporator and condenser are unchanged, the operating performance of a solar jet refrigeration system with the variation of solar radiation are studied, and multi-ejector parallel optimization is adopted. The results show that when solar radiation is at the design value, the performance coefficient and cooling capacity of the refrigeration system reach their maximum values. As solar radiation increases or decreases, the performance coefficient and cooling capacity of the refrigeration system will decrease. During the summer, the average cooling capacity of the system with three-ejector parallel and the days meeting the cooling demand are both increased by about 21% compared to the single-nozzle system.
