本文探讨了寒冷干燥地区建筑物的有效新风加湿方法。对采用转轮除湿实现空气加湿的空气处理机组进行了研究。对三种类型的空气处理机组在不同环境湿度比下进行了优化分析，并对除湿轮表面积比（Ar）、除湿轮流量比（Fr）、转速（RS）、级数等参数的影响进行了分析。讨论了在优化结果的基础上，提出了一种三级除湿转轮、三股新风的空气处理机组。对于该装置，每个干燥剂转轮的阿里斯3和Fr可在1至9之间调整。它可以满足各种环境条件下的新鲜空气加湿。在此基础上，针对乌鲁木齐冬季的环境条件，讨论了两种控制策略。满意率达95%以上。
Efficient fresh air humidification methods for buildings located in cold and dry climate regions are discussed in this paper. Air handling units that use desiccant wheels to realize air humidification are studied. Optimization analysis is carried out for three types of air handling units under different ambient humid ratios and effects of desiccant wheel facial area ratios (Ar) between dehumidification air and humidification air, air flow rate ratio between dehumidification air and humidification air (Fr), rotation speed (RS), stage number etc., are discussed. Based on the optimization results, an air handling unit that has 3 stages desiccant wheels and 3 streams dehumidification air is proposed. For this device,Aris 3 for each desiccant wheel andFrcan be adjusted from 1 to 9. It can satisfy fresh air humidification in a wide range of ambient conditions. Based on this device, two control strategies are discussed based on Urumchi winter ambient conditions. The satisfactory rate is over 95%.
