| 摘 要： | 用正交实验法研究下送风通风空调房间的通风特性,下送风通风空调房间的通风效果及房间热分布特性一般是通过房间通风效率(或能量利用系数)ET来衡量的,因此选定通风效率ET做为实验指标,研究了送风口型式、送风速度、送风温度、热源发热量等通风特性参数对下送风通风空调房间通风特性的影响及其影响程度大小,并利用回归分析法得出通风效率ET与送风口型式、送风速度、送风温度、热源发热量的线性回归公式。

| Abstract: | The ventilation characteristics of the under-floor air distribution room was studied in this paper through orthogonal experimentation, generally, the ventilation effect and the distribution of heat are described by the ventilation efficiency ET is taken into account in the under floor air distribution room, so the ventilation efficiency ET is selected as the experiment index. We find that four factors (the inlet type, air velocity, air temperature, power of heat source) have enormously influenced on the ven... |
