卧室工位空调舒适性的实验与CFD模拟研究

Experimental and CFD studies on the performance evaluation of a bed-based task/ambient air conditioning system

近年来,针对于工位空调(TAC)的应用研究越来越多,原因在于它有助于提高热舒适性,改善室内空气质量.而把工位空调引入到睡眠环境下的卧室中使用,可以提高夜间睡眠状态下的热舒适性.为此,设计了两种应用于睡眠环境的工位空调系统模式,采用实验研究与CFD数值模拟研究的方法,分析两种设置方式的热环境控制性能,以期找到更适合睡眠环境热舒适性的设置模式.实验数据和模拟分析表明,第二种设置模式是更适用于作为睡眠环境下卧室的空调方式.

In recent years,a large number of studies have been conducted on task/ambient air conditioning（TAC）because it helps enhance thermal comfort,improve indoor air quality.Therefore,TAC is introduced in the bedroom among sleep environment to improve sleeping at night under the thermal comfort.This paper presents a detailed description of an experimental rig for the bed-based TAC system at two settings.The experimental results on the operating performances of the bed-based TAC system at the two settings in terms of thermal environment control are analyzed and reported.The purpose is to find a better sleep environment thermal comfort setting mode.Experimental data and simulation analysis show that the second settings are more suitable for the bedroom air conditioning system as sleep environment.
