摘　　要：针对纺织厂空调系统的核心设备——喷水室的等焓加湿和冷却减湿2个典型过程,研究影响热湿交换效率的两个关键因素,空气流速和水气比。经过试验台大量的规律性试验,得到热湿交换效率的回归公式,然后经过纺织厂现场测试对进行验证和修正。在国内首次提出了满足纺织工艺要求的前提下空气流速可以达到7.07 m/s,是目前低速喷水室的两倍;同时水气比可以降低到0.48,不到目前低速喷水室的1/2。研究结果可使设备小型化,大量减少工厂辅房的占地面积和水系统能耗,有助于高速喷水室在国内的推广应用。To the two typical processes in the core equipment of the air-conditioning system- air-washer in textile mill ,the cooling dehumidification and the isenthalpic humidification .Air velocity and water-air ratio of the key factors affecting the efficien-cy of heat and mass transfer are researched .The regression formula of the efficiency of heat and mass transfer is gained by vast ex-periments .Verifying and revising the law by field testing in textile mill .in recently year .The first time proposed that the velocity of air can reach 7.07m/s in domestic.It is double to low speed air-washer’s.And water-air ratio can drop to 0.48.It is one half to low speed air-washer’s.The research results can miniaturize the equipment and cut down the floor space ,decrease the energy of water system.This will benefit the improvement and application of the high speed air -washer.
