独立新风变风量系统在负压隔离病房平疫转换中的应用

平疫转换病房空调系统应满足普通病房、负压病房和负压隔离病房的不同规范要求。梳理了不同的医院设计规范对各类型病房的空调系统设计参数要求,包括室内温湿度、换气次数、新风量、压力控制、气流组织、过滤等级等。总结了平疫转换病房设计参数要求。在普通变风量系统的基础上,提出了独立新风变风量系统,并以某病房为例进行了分析,给出了不同病房模式的控制策略。

Application of independent outdoor air variable air volume systems in epidemic conversion of negative pressure isolation wards

The air conditioning system of epidemic conversion wards should meet the different standard requirements of general wards, negative pressure wards and negative pressure isolation wards. Sorts out the design parameters of air conditioning system for each type of wards according to different hospital design standards, including indoor temperature and humidity, air change rate, outdoor air rate, pressure control, air distribution, filtration classification and so on. Summarizes the design parameter requirements of the epidemic conversion wards. On the basis of ordinary VAV systems, proposes an independent outdoor air VAV system, and taking a ward as an example, suggests the control strategies of different ward modes.
