上侧送风,下侧回风的气流组织方式。简称侧送风方式(见示意图)。它是空调房间气流组织中应用最为广泛的一种方式。一、侧送风气流组织计算中存在的问题在计算空调精度较高的房间(恒温精度<±0.1℃)的侧送气流时,《空气调节》和《空气调节设计手册》中均采用了试算法求解。这既花费大量时间又不方便。首先假设送风口的出风速度V_0,然后计算送风射流自由度,再根据自由度((F_n)~(1/2))/d_0满足速度衰减和防止噪声确定允许的送风速度。若假设的V_0小于或等于实际允许的送风速度,则认
Air distribution on the upper side and return air on the lower side. Abbreviated side air supply (see schematic). It is the most widely used method of airflow organization in air-conditioned rooms. First, the problems in the calculation of the side air flow organization In the calculation of air conditioning accuracy room (temperature accuracy <±0.1 °C) side air flow, “air conditioning” and “air conditioning design manual” are used in the test Algorithm solution. This is both time-consuming and inconvenient. First, suppose the air outlet speed V_0, then calculate the degree of freedom of the air jet, and then according to the degree of freedom ((F_n) ~ (1/2)) / d_0 meet the speed attenuation and prevent noise to determine the allowed air speed. If the hypothetical V_0 is less than or equal to the actual allowable air supply speed, then
