ABSTRACT

Capillary driven ejector refrigerator is a new refrigeration system, which can use solar energy and other low-grade heat sources. In this paper the performance of the refrigeration system is simulated numerically. The flow and heat transfer characteristics in a solar collector, generator, ejector, condenser and evaporator are analyzed and calculated. The results show that when the generating temperature is higher than 75−80 °C and the environmental temperature is lower than 35 °C, the system can work normally; the coefficient of performance of this refrigeration system is in the range of 0.05−0.15 by use of water as a refrigerant. The cooling capacity and COP increase with increasing generative temperature and decreasing condensing pressure.
