Abstract:

The solar jet refrigeration system has the off-design characteristics of intermittent operation.In order to extend the operating time of the solar jet refrigeration system and achieve the optimal operating characteristics of the solar jet refrigeration system, the solar heat storage subsystem has been modified.Based on the thermodynamic model of the solar jet refrigeration system, the off-design thermodynamic characteristic of the system using R161 as refrigerants was studied.The results indicated that the improvement of the solar heat storage heating system can increase the operating time range of the solar jet refrigeration system and refrigerating efficiency.As compared to the conventional solar jet refrigeration system,the modified solar jet refrigeration system started to refrigerate two hours earlier, and its operating time was increased by 12.5%, and the coefficient of performance (COP) of the system was increased by 8.5%.The research results provide theoretical reference for the engineering design of the modified solar jet refrigeration system.

Key words: modified solar jet refrigeration system, off-design, COP, R161, operation time
