摘要
本文对具有高发热量烟机的4～5米高的大面积空调厂房进行流场和温度场的数值模拟。比较了不同的送、回风口布置方式对厂房内的温度分布的影响。研究发现卷烟高大厂房内温度沿高度分层明显。而中等高度下送风和上回风可以有效地利用温度分层,不仅在工作区保持较均匀工作温度,而且可以节省能源。
Numerical simulations have been carried out to investigate the influence of the position variations of the air inlets and outlets on the temperature distribution in a large air conditioning workshop of 4-5 meters height with high heat-releasing tobacco machines. The temperature field appears stratification along the height. High position of the outlet can improve the taking out the heat in the workshop, while low position of the air inlet can increase the stratification of air temperature. Simulation results show that temperature stratification can be effectively used by air supply below and air return upward in middling height. It can not only achieve the desired mixed temperature in the working area, but also can save the energy.
