摘要

太阳能集热器是太阳能热驱动制冷系统中的关键部件，在系统能量转化和储存利用过程中起到决定性作用。采用动态模拟及多变量优化的方法对不同形式太阳能集热器的吸收式制冷系统进行研究。结果表明：在太阳能资源一般的地区，采用真空管式太阳能集热器的单效吸收式制冷系统和槽式太阳能集热器驱动的双效吸收式制冷系统运行平稳且能耗相对较少；基于优化参数，对不同系统的太阳能保证率、系统性能系数进行比较，真空管型太阳能集热器驱动的单效吸收式制冷系统的太阳能保证率最高，达到39.9%。该结论可以为太阳能集热器在热制冷领域中的应用提供指导。

Abstract

Solar collector is a key component of solar thermal driven refrigeration system

which plays a decisive role in energy conversion

storage and utilization. The absorption refrigeration system with different forms of solar collectors is studied by using the methods of dynamic simulation and multivariable optimization. The results show that

the single effect absorption refrigeration system with vacuum tube solar collector and the double effect absorption refrigeration system driven by trough solar collector run smoothly and consume relatively less energy in areas with common solar energy resources. Based on the optimized parameters

the solar energy assurance rate and system performance coefficient of different systems are compared. The solar energy assurance rate of the single effect absorption refrigeration system driven by vacuum tube solar collector reaches 39.9%

which is the highest.The conclusion can provide guidance for the application of solar collectors in the field of thermal refrigeration.
