摘要

太阳能喷射制冷系统具有变工况间歇性工作特点，为提高太阳能喷射制冷系统的使用时间，获得太阳能喷射制冷系统的最佳变工况工作特性，提出了改进太阳能蓄热水箱流程，并在建立太阳能喷射制冷系统热力学模型基础上，选择新型环保制冷剂R161为工质研究了太阳能喷射制冷系统变工况热力学特性。结果表明，与传统太阳能喷射制冷系统相比，所改进的太阳能蓄热水箱结构增加了太阳能喷射制冷系统工作时间和系统制冷效率，系统工作时间延长12.5%，系统提前2 h开始工作，系统的制冷效率提高8.5%。该研究结果可为改进型太阳能喷射制冷系统的工程设计提供理论参考。

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.
