Study on the dedicated outdoor air system (4):Outdoor air dehumidification units
摘要：
新风机组是独立新风系统的核心部件，其性能、价格、尺寸直接影响独立新风系统的应用。分析了该系统现行几种新风机组的特点，指出了目前采用的新风除湿技术存在的问题。提出了一种新型的新风除湿空调机组，实验结果表明，这种机组能大幅增加除湿量，提高出风温度，其各项性能指标、价格、尺寸均优于现行的新风机组。
Abstract：
The outdoor air handling unit is the core component of a DOAS (dedicated outdoor air system) that sensible load and latent load are controlled separately. Its performance, price, and size significantly affect the application of DOAS. Presents the characteristics of several current outdoor air handling units of DOAS, and lists the existing problems of the outdoor air dehumidification technology. Proposes a new type of outdoor dehumidification air conditioning unit. Experimental results show that the outdoor air handling unit greatly increases the amount of dehumidification and the air supply outlet temperature with better indexes of the performance, price and size than the conventional outdoor air handling unit.
