| 摘 要： | 炯分析是优化热力系统性能的一种有效工具.推导了太阳能喷射与压缩复合制冷系统各部件损失计算公式,分析了影响系统损失的主要部件及因素.结果表明,太阳能喷射与压缩复合制冷系统各装置中,集热器(火用)损失最大,其次是冷凝器和喷射器.在几种典型工况下,三者占系统总损失的73.28%.在系统制冷量、集热温度、蒸发温度和冷凝温度不变时,随着中间冷却器蒸发温度的升高,系统损失逐渐减少.

| Abstract: | Exergy analysis is used as a tool to analyze the performance of a refrigeration cycle.Exergy destruction calculation formulas of parts of a solar ejector-compression combined cooling system are deduced,and major factors working on the exergy destruction of the system are analyzed.The exergy analysis results of the cooling system show that the solar collector has the largest exergy destruction in the total exergy destruction,next is the condenser,and the third is the ejector.For some typical operating condit... |
