摘要
探讨了冷却顶板空调系统对新风承担湿负荷的要求及实施方案 ,认为吸附除湿优于冷却除湿 .对利用除湿转轮处理系统湿负荷及实施方案的可行性进行了实验研究 ,结果表明 ,当夏季室外空气温度低于 30℃及相对湿度低于 80 %时 ,除办公类建筑外 ,除湿转轮均可满足系统运行要求 ;对于高温高湿地区 ,结合前置表冷器对新风进行预处理后利用转轮除湿不仅可以满足室内湿度的要求 ,而且可以达到低湿度 ;利用改变除湿转轮再生温度和处理风量的方法可以调节室内相对湿度 .
The demands and schemes for the moisture load disposal in cooling ceiling air-conditioning systems by using fresh air were investigated,reaching the conclusion that adsorption dehumidification is better than cooling dehumidification. Experimental results of the moisture load removing by rotary dehumidifier and the feasibility of implementation schemes show that,in summer,the rotary dehumidifier can satisfy the system demands when the outdoor air temperature and humidity are respectively lower than 30℃ and 80% besides office buildings,and that,in the high-temperature and high-humidity areas,the rotary dehumidifier can satisfy the demand for indoor humidity and the demand for low humidity by the head surface cooler preprocessing of the fresh air. Moreover,the indoor relative humidity can be controlled by regulating the regeneration temperature and the fresh air flowrate of rotary dehumidifier.
