手术部净化空调新风处理方案解析

Clean air conditioning outdoor air treatment method analysis and schemes for operating department

针对目前手术部净化空调系统常用空气处理模式存在的湿度偏离问题,提出了4种方案并进行了湿负荷计算,通过对比分析,选择第4种方案,即新风机组配置一级水冷表冷器,新风处理至过冷过干并与部分回风一次混合,另一部分回风在循环机组内先经冷却除湿并与一次混合空气进行二次混合,再热或冷却微调送风温度的方案。

In view of the humidity deviation of air treatment mode commonly used in the clean air conditioning system of the operating department at present,proposes four schemes and calculates the moisture load.Through comparative analysis,selects the fourth scheme,that is,the outdoor air handling unit is equipped with a primary water-cooled surface cooler,and the cool and dry outdoor air is treated to be subcooled and subdried and mixed with part of the return air for the first time,the other part of the return air is cooled and dehumidified in the circulating unit and mixed with the primary mixed air for the second time,and then heated or cooled to fine-tune the air supply temperature.
