APPLICATION OF INDUSTRIAL WASTE HEAT IN SOLAR REFRIGERANT SYSTEM: AN EXAMPLE OF A TEXTILE FACTORY IN JINJIANG

ABSTRACT
A waste heat recovery solar ejector-compression refrigeration system was designed, and a thermodynamic model was established to deal with the waste heat produced by a textile factory in China. The influence of the outlet temperature of the heat recovery device on the coefficient of performance and the generator heat load were researched under different refrigerants, the energy saving efficiency between waste heat recovery solar ejector-compression refrigeration system and its conventional solar ejector refrigeration system was compared. This paper showed that a higher outlet temperature resulted in a lower heat load of generator and a higher coefficient of performance. When the temperature increment was 30˚C, the heat load of the generator could be saved by 31.98%, and the coefficient of performance could be increased by 42.94%.
