摘要(Abstract)：

针对双冷源温湿度独立控制空调系统需要两套冷源和COP低的问题，提出了太阳能驱动除湿转轮与蒸发冷却复合空调系统。系统能对新风进行降温除湿处理的同时制备出高温冷水，高温冷水供给新风处理机组和空调显热末端。建立了系统数学模型，应用TRNSYS软件对系统动态特性进行了分析。模拟结果表明：当系统再生温度为70 ℃时，典型周新风处理后的温度范围为16.6～17.8 ℃，制备高温冷水的温度为15.5～16.8 ℃。与双冷源温湿度独立控制空调系统相比，典型周本系统的平均COP可高出57.9%和平均节电率为36.2%，典型月可减少45.9%的CO_2排放量。
For the problem that double cold source temperature and humidity independent control(THIC) air conditioning system requires two sets of cold sources and low COP，a solar driven desiccant wheel and evaporative cooling composite air conditioning system was proposed.The system can prepare high-temperature chilled water while cooling and dehumidifying the fresh air，and the high-temperature chilled water is supplied to the fresh air handling unit and the sensible heat terminal of air conditioning.The mathematical model of the system was established and the dynamic characteristics of the system were analyzed by TRNSYS software.The simulation results show that when the regeneration temperature of the system is 70 ℃，the temperature range of typical weekly fresh air treatment is 16.6～17.8 ℃，and the temperature for preparing high-temperature chilled water is 15.5～16.8 ℃.Compared with the double cold source THIC air conditioning system，the average COP of the system can be increased by 57.9% and the average power saving rate is 36.2% in the typical week，and the carbon dioxide emissions can be reduced by 45.9% in the typical month.
