为了改进地板送风空调系统的效能,本文提出一种新型送风方式,即包围热源式地板条缝送风。作者分析了此种送风方式的空气分布与热分布机理,经由量纲分析和模型实验的方法,得到了影响热分布的一系列因素及其内在关系,提出了确定工作区进入热量的比例数α值的经验公式。无论这些因素如何变化,只要使准则数A_γ(V_0/Q_0)~(1.75)=9,即可获得热量比例数α的最小值。式中V_0是条缝出风速度,Q_0为房间每m~2送风量。
In order to improve the performance of the floor air conditioning system, this paper presents a new way of air supply, that is, surrounded by heat source floor slats air supply. The author analyzes the air distribution and heat distribution mechanism of this air supply mode. Through the methods of dimension analysis and model experiment, a series of factors affecting the heat distribution and their internal relations are obtained. The empirical formula of α value. No matter how these factors change, as long as the criterion number A_γ (V_0 / Q_0) ~ (1.75) = 9, you can get the minimum heat ratio α. Where V_0 is the slit wind speed, Q_0 for the room every m ~ 2 air volume.
