Application of industrial waste heat in solar refrigerant system: An example of a textile factory in Jinjiang

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%.
