某住院部负压病房平疫结合空调系统设计
Air conditioning system design combined with peacetime and epidemic period for negative pressure wards in an inpatient department
摘要：
传染性疾病严重威胁人们的生命与健康,如何快速应对突发性疫情等公共卫生事件尤其重要。本文以某医院住院部项目为例,采用并联一大一小2台新风机组,小风量新风机组负责平时工况,大风量新风机组负责疫情时期工况。通过这种平疫结合双工况运行的设计方案,实现了快速转换工况,并且平时运行能耗较低。此外,对负压病房进行了气流组织模拟,经验证设计工况能满足室内的热舒适要求,可为其他类似项目设计提供参考。
Abstract：
Infectious diseases pose a serious threat to people’s lives and health,and it is particularly important to respond quickly to public health emergencies such as sudden epidemics.This paper takes the inpatient department project of a hospital as an example,using two parallel outdoor air units,one large and one small.The small air volume outdoor air unit is responsible for the peacetime operating conditions,while the large air volume outdoor air unit is responsible for the epidemic operating conditions.This design scheme for dual-mode operation,combined with peacetime and epidemic period,allows for rapid switching of operating conditions while maintaining low energy consumption during peacetime operation.In addition,air distribution simulation is conducted for the negative pressure ward to verify that the design conditions can meet indoor thermal comfort requirements,providing a reference for the design of other similar projects.
