摘　　要：以“太阳府”别墅为例,搭建TRNSYS模型对夏季建筑负荷进行模拟计算,并将太阳能单效LiBr风冷吸收式系统应用于该建筑中,研究该系统的制冷效果。结果表明:全年最大冷负荷主要集中在7月份和8月份,最大冷负荷为37089W,冷指标为92.72 W/m^2;供/回水温度的均值能达到9.31℃/14.72℃,高于设计数值7℃/12℃,温差为5.41℃,高于设计值5℃,该制冷系统在正常工作时能够满足夏季的制冷需求。In this paper,"Sun mansion"villa as an example,TRNSYS model is built to simulate the building load in summer,the solar energy single effect LiBr air-cooled absorption system is applied to the building to study the refrigeration effect of the system.The results show that the maximum cooling load is mainly concentrated in July and August,the maximum cooling load is 37089w,and the cooling index is 92.72 W/m^2;The average temperature of water supply/return can reach 9.31℃/14.72℃,which is higher than the design value of 7℃/12℃;The temperature difference is 5.41℃,which is higher than the design value of 5℃,and the cooling system can meet the cooling demand in summer during normal operation.
