某火车站候车大厅热舒适性模拟研究

Study of Simulation of Thermal Comfort for Railway Station Waiting Hall

针对某火车站候车大厅的空调系统,利用CFD技术,运用商用软件Airpak,采用RNG方程模型,对其室内热舒适性进行预测。通过分析计算结果,表明人体区域温度,相对湿度,PMV及PPD值均能满足要求,为工程设计提供可靠的理论依据。

Aiming at the air conditioning system of one railway station Waiting Hall, this paper gives a forecast to the indoor thermal comfort by using CFD technology, commercial soffware-Airpak and according to the RNG equation model. The analytic results show that the human body temperature, relative humidity, regional PMV and PPD all can satisfy the requirements and provide the reliable theory basis for engineering design.
