摘　　要：设计太阳能吸收式制冷-海水淡化联产系统,以大连、深圳、上海3个沿海城市为例,选取一栋别墅建筑作为研究对象,利用Matlab对系统容量匹配和经济性进行比较。结果表明:对于同一栋别墅,太阳能集热器面积由建筑物所在地区的建筑冷负荷确定,大连最小,深圳其次,上海最大;淡水产量与建筑冷负荷呈正比关系;联产系统在上海初投资最高,在深圳运行维护费用最高,在大连投资回收期最长;相比太阳能吸收式制冷系统,太阳能吸收式制冷-海水淡化联产系统的投资回收期可缩短9.4%。A combined solar absorption refrigeration and desalination system is designed. Taking coastal cities in Dalian, Shenzhen and Shanghai as examples,a villa building is selected as a simulation object to compare the capacity matching and economy of the system by Matlab. The results show that for the same villa,the solar collector area is determined by the building cooling load in the area where the building is located,Dalian is the smallest,Shenzhen is the second,Shanghai is the largest,and the freshwater output and the building cooling load also show the same proportional relationship;the initial investment of the system in Shanghai is the largest,the operation and maintenance cost of system in Shenzhen is the largest,and the payback period of the system in Dalian is the longest;the payback period of the combined solar absorption refrigeration and desalination system can be shortened by 9.4% compared with the solar absorption refrigeration system.
