摘要:
针对下部有集中热源的地板送风空调小室,利用PHOENICS软件,对多种工况下室内气流流动的速度场和温度场进行了模拟,利用模拟结果计算对流热转移量,得出对流热转移量的变化规律。分析了影响对流热转移量的相关因素,主要是由于送风冷射流与热源的热射流在不同的影响因素下对室内气流流动及温度分布产生影响,从而造成对流热转移量的变化。结果表明:地板送风空调小室的对流热转移量与热源数目、送风口密度、热源强度、送风量4个因素有关; 回风口数目对对流热转移量的影响很小,可以忽略不计。
Abstract:
According to small air conditioner room with floor board air supply and having hot source in concentration sends, authors simulated the temperature and velocity field of many conditions using PHOENICS software; computed the convection heat transfer volume with simulation result, and deduced its variety regulation. By analyzing the correlation factors, the main reason was that the cold air jet and the heat source jet influenced the indoors velocity field and temperature field in the different conditions, therefore, the convection heat transfer volume would have different variety. The results show that the convection heat transfer volume of small air conditioner room with floor board air supply relates to four kinds of factors as follows: the number of hot source, the density of air supply outlet, the intensity of hot source and the volume of air supply; the number of air inlet has a little influence and it can be neglected.
