摘要 为解决现有通风空调系统中采用混合送风或置换送风模式存在的问题,在传统顶板水平贴附送风的基础上,提出了一种基于壁面贴附的空气幕式送风技术。采用实验测试的方法研究了与这一新型送风模式热舒适性相关的气流组织特性参数,并通过热舒适指标计算分析了该模式下室内人员的热舒适性。研究表明,壁面贴附式送风具有工作区人员热舒适强的特点,并且采用该模式送风时,工作区允许风速和温度较我国的传统设计要求可以有一定的提高,因此适用范围更为广泛。 To solve the problem existing in ventilation and air conditioning system using mixing or displacement ventilation mode,a novel ventilation mode named wall attached air curtain is presented in this paper,which is based on traditional ceiling attached air supply. The air distribution characteristic parameters related to the thermal comfort of this mode is studied by experimental test. The indoor human thermal comfort is obtained by calculating the thermal comfort index. The current results show this ventilation mode has the advantage of higher thermal comfort in occupied zone. Meanwhile,when using this ventilation mode,the allowable air speed and temperature in occupied zone are higher than that in traditional HVAC design of China. Therefore,the applying range of this new ventilation mode is wider.
