关于传染病医院房间的压差控制及通风能耗问题探讨

Discussion on Energy Consumption of Ventilation and Differential Pressure Control of Infectious Disease Hospital

在传染病医院项目的实际运营过程中,院方反馈各分区房间压差控制精度不够及通风系统使用能耗较高的问题较为突出,此类问题的发生影响到医院的实际使用,也给暖通设计师做出了提示;通过查阅相关资料和众多传染病医院设计的经验总结,设置智能适应新排风调节变风量模块,可以解决房间在压差控制上的问题,保证功能房间的压力梯度。另外,在传染病医院的功能布局中,有较多的无外窗房间,此类房间需要设置分区集中通风系统,排风量较大,在设计中采用排风显热回收系统,可以减少新风系统使用能耗。

In the actual operation process of infectious disease hospital project,the insufficient control accuracy of room pressure difference in each zone and ventilation system uses high energy consumption are prominent.The occurrence of such problems affects the actual use of the hospital.By consulting relevant materials and summary of experience in the design of many infectious disease hospitals,setting up intelligent adaptation to the fresh air and exhaust air regulation variable air volume module can solve the problem of room pressure difference control and ensure the pressure gradient of the functional room.There are many rooms without windows in the infectious disease hospital and need to set up an exhaust system.Due to the large exhaust air volume,exhaust air sensible heat recovery system can effectively reduce the energy consumption of the fresh air system.
