摘　　要：以北京某办公建筑为研究对象,建立双温冷源温湿度独立控制空调系统。基于传统湿度控制方式,提出2种优化控制方式。采用模拟方法,计算比较3种湿度控制方式供冷期典型日、供冷期主要设备的耗电量。传统控制方式:湿度控制系统定送风温度、定送风量运行。优化控制方式1:湿度控制系统定送风温度、变送风量运行。优化控制方式2:湿度控制系统定送风量、变送风温度运行。与传统控制方式相比,优化控制方式1、2的典型日节电率分别为7.78%、6.64%。与优化控制方式1相比,虽然优化控制方式2的节电率有所下降,但各小时耗电量更加趋于均衡。与传统控制方式相比,优化控制方式1、2的供冷期节电率分别为10.08%、8.82%。对于3种控制方式,高温冷水机组耗电量最高,其次是低温冷水机组,风机与水泵耗电量最低。Taking an office building in Beijing as the research object,a dual-temperature cold source temperature and humidity independent control air conditioning system was established.Based on the traditional humidity control mode,two optimized control modes are proposed.The simulation method is used to calculate and compare the power consumption of three humidity control modes for a typical day during the cooling season and for the main cooling equipment during the cooling season.Traditional control mode:the humidity control system operates with fixed air supply temperature and fixed air supply volume.Optimized control mode 1:the humidity control system operates with fixed air supply temperature and variable air supply volume.Optimized control mode 2:the humidity control system operates with fixed air volume and variable air temperature.Compared with the traditional control mode,the typical daily power saving rates of the optimized control modes 1 and 2 are 7.78%and 6.64%,respectively.Compared with the optimized control mode 1,although the power saving rate of the optimized control mode 2 has decreased,the power consumption of each hour tends to be more balanced.Compared with the traditional control mode,the power saving rates of the optimized control modes 1 and 2 during the cooling period is 10.08%and 8.82%,respectively.For the three control modes,the power consumption of high temperature chiller is the highest,followed by low temperature chiller,and the power consumption of fan and pump is the lowest.
