摘　　要：对太阳能喷射-压缩复合供冷系统性能进行了分析计算。以太原地区某建筑为供冷对象,构建了复合供冷系统的模拟平台;以热平衡方程为基础,结合TRNSYS软件,对系统的耗电量、供冷量、综合性能系数等进行了计算分析。结果表明,复合供冷系统与纯压缩制冷系统相比可节约40%以上的电量;喷射制冷子系统可为用户提供50%以上的冷量;系统综合热性能系数为0.36,综合机械性能系数为18.97。太阳能喷射-压缩复合供冷系统不仅可以充分利用太阳能,还能够平衡系统制冷量与建筑冷负荷的需求,具有很好的节能优势和实用性。The performance analysis on the solar ejection-compression refrigeration system was carried out using a building in Taiyuan as the cooling object,a simulating model of the combined refrigeration system was created.The performance of the system such as the power consumption,refrigerating capacity,and coefficient of performance was calculated on the basis of the thermal equilibrium by using the TRNSYS software.The results show that more than 40% of electrical energy could be saved through the solar ejection-compression refrigeration system,compared with common compression refrigeration system;more than 50%of the refrigerating capacity is provided by the ejection refrigeration sub-system;the system comprehensive thermal coefficient is 0.36 and the comprehensive mechanical coefficient is 18.97.Solar ejection-compression refrigeration system makes full use of solar energy,and balances the demands between refrigerating capacity and cooling-loading system of buildings,which has good energy-saving advantage and practicability.
