北方寒冷地区医院洁净手术室供暖节能分析

Heating in the Cleanroom of Hospital in North China

本文运用CFD技术作为辅助工具观察热水采暖系统对医院四级手术室气流组织的影响,研究中采用了k-ε模型,并用FLUENT软件进行求解。最后在实地进行实验数据采集,进一步验证软件模拟结果的正确性。在满足国家规范的基础上,探讨了北方地区热水采暖取代热泵空调机组加电采暖的可行性。

This paper illustrated how to use the CFD method as an assistant tool to make a research of the way of hot-water heating in the IV cleanroom, which probably has an effect on airflow pattern. The Reynolds-averaged Navier-Stokes equations were solved using a finite-volume method. Different plans were established for the cleanroom and simulated by the FLUENT software. It was compared to the data which comes from field experiment. Finally, a concern was attached to the possibility of applying hot-water heating to replace the traditional heating way.
