摘　　要：利用TRNSYS软件的Type683模块,以处理风出口温度、再生风进出口温度、再生风出口含湿量和除湿性能系数DCOP为性能评价指标,采用控制变量法研究了处理风进口温度和含湿量、再生风进口含湿量和再生风风量对转轮除湿性能的影响。研究结果表明:在指定处理风出口含湿量情况下,处理风进口温度和含湿量都不宜过高,应采用表冷器降温除湿进行预处理,这样可降低再生能耗、再冷能耗和再生排风余热,且处理风进口温度降低会提高除湿性能系数DCOP,但处理风进口含湿量降低会使DCOP有所下降;同时再生风进口含湿量也是越小越好,但再生风通常是新风,其进口含湿量无法控制。因此,若工程上采用再生排风热回收以降低再生能耗时,应只回收排风显热以控制再生进风含湿量;而再生风风量大小对处理风出口温度、再生风进口温度、DCOP均没有影响,故再生风量不宜过大,否则会增加再生风的加热能耗和风机能耗。一般再生区占转轮的1/4,因此,再生风量为处理风量的1/3为宜。Using the Type683 module of TRNSYS software and taking the process air outlet temperature, re-generation air inlet and outlet temperature, regeneration air outlet moisture content and dehu-midification performance coefficient DCOP as performance evaluation indexes, the influences of process air inlet temperature and moisture content, regeneration air inlet moisture content and regeneration air volume on the dehumidification performance of the rotary were studied by using control variable method. The results of research show that when the outlet moisture content of the process air is specified, the inlet temperature and moisture content of the process air should not be too high, and the surface cooler should be used for cooling and dehumidification, which can reduce the regeneration energy consumption, re-cooling energy consumption and regeneration exhaust waste heat. And the dehumidification performance coefficient DCOP will be improved when the process air inlet temperature decreases, while the decrease of process air inlet moisture content will decrease the DCOP;At the same time, the inlet moisture content of the regeneration air is also the smaller the better, while the regeneration air is usually fresh air, the moisture content of it cannot be controlled. Therefore, if regeneration exhaust heat recovery is used in engineering to re-duce regeneration energy consumption, only sensible exhaust heat should be recovered to control the inlet moisture content of the regeneration air;The size of the regeneration air volume has no in-fluence on the outlet temperature of the process air, the inlet temperature of the regeneration air and DCOP. Therefore, the regeneration air volume should not be too large, otherwise it will increase the heating energy consumption of the regeneration air and the fan energy consumption. Generally, the regeneration area accounts for 1/4 of the rotary, so the regeneration air volume should be 1/3 of the process air volume.
