固体吸附除湿技术用于民用建筑中央空调系统的经济性分析

The economic analysis on solid-adsorption desiccant technology used in the central air-conditioning system of civil buildings

针对传统空调冷却除湿方式的高能耗,提出将固体吸附除湿技术应用于民用建筑中央空调系统,并对采用这种除湿方式的干式风机盘管加固体吸附独立除湿新风系统与传统的风机盘管加新风系统在运行能耗方面进行经济性实例分析,结果表明干式风机盘管加固体吸附独立除湿新风系统较传统风机盘管加新风系统其夏季空调工况每天减少约14W/m2,有效降低建筑能耗。

According to the high energy consumption of traditional dehumidification mode,the technology of solid-adsorption desiccant is proposed to be used in the central air-conditioning system of civil buildings,and the economic analysis of an example using dry fan coil units plus fresh air system with solid-adsorption desiccant and traditional fan-coil unit plus fresh air system separately is given.The results showed,compared with traditional fan-coil unit plus fresh air system,the dry fan coil units plus fresh air system with solid-adsorption desiccant can save 14W/m2 in the summer per day and it decrease the building energy consumption.
