摘要
本文提出了一种利用TCM模型进行医院手术室热舒适性分析的CFD仿真研究。本研究旨在利用由ISO7730提出的预测平均投票(PMV)模型分析室内的热舒适性。分析讨论了速度、温度和相对湿度、空气的平均年龄,以及人体表面的温度和相对湿度的分布,计算得到了人体不同部位的PMV和PPD值。仿真结果表明,在人体表面某些部位的PMV和PPD值不在标准ISO定义的可接受的范围,但此手术室的舒适性满足中国国家标准GB/T18049的要求。最后指出TCM模型是一种更全面的热舒适性分析模型。
This paper presents a CFD study for thermal comfort in a hospital operating room. The research aims to analyze the indoor thermal comfort using the PMV model which has been presented by ISO7730. Solutions of the distribution of airflow velocity, temperature, and relative humidity, mean age of air, temperature and relative humidity of human body surface are presented and discussed. The PMV and PPD are calculated for assessing thermal comfort based on TCM model. The simulation results show that the values of PMV and PPD in some parts of human body surface are not within the standard acceptable range defined by ISO, but this operating room＇s comfortableness satisfies China national standards GB/T18049 request. It is found that TCM model is a more comprehensive model for thermal comfort analysis.
