摘　　要：对对象建筑及太阳能集蓄热系统进行TRNSYS模拟,分别得出房间逐时冷负荷及5,15,25℃等3种设计蒸发温度下,不同水箱容积与集热面积比(S)时,系统的发生温度、制冷量及系统性能系数(COP)的变化规律.结果表明:在太原市的夏季气象条件下,对以R141b型制冷剂为工质的小型太阳能喷射制冷系统,当蒸发温度在5~25℃时,S值的最佳设计范围为0.015~0.030,且设计蒸发温度越高,S值应越高.Systems of room and solar collector were simulated by the TRNSYS software in this paper. The curve of cooling load was drawn and the hourly variation of generation temperature, cooling capacity and coeffi-cient of performance （COP） was simulated under different collector area and tank volume ratio （S） , when de-sign evaporation temperature was 5, 15, and 25 ℃ respectively. Result shows that the optimum value of S va-ries from 0. 015 to 0. 030 when R141b is chosen as the working fluid and evaporation temperature ranges from 5 to 25 ℃in the summer of Taiyuan. And the value of S should be greater when the designed evaporation tem-perature is higher.
