摘要:
近年来,喷雾降温作为一种新型的降温方式,降温效果好,耗电量低,不产生其他污染物,是一种高效节能的降温装置,逐渐受到人们的重视.然而,国内外对喷雾降温的数值模拟方面的研究相对较少,尤其缺乏对喷雾降温下温度与其影响因素的函数关系的研究,因此喷雾降温方案的设计依然停留在经验阶段,没有理论依据,限制了该项技术的进一步推广.建立温度与时间之间的双折线模型,通过实验数据与模型的回归分析验证了模型的准确性.分析了湿度对温度平衡时间和降温速率的影响,根据实验数据绘制了湿度-温度平衡时间和湿度-降温速率包络曲线,并利用曲线和建立的温度-时间关系模型给出了喷雾降温设备的降温幅度区间计算方法.模型可以用于分析时间对喷雾降温效果的影响和预测喷雾设备的降温幅度,为喷雾降温设备的选择和方案的设计提供理论依据,进而为推广喷雾降温的应用范围打下理论基础
Abstract:
As an energy-efficient and environmental friendly cooling method. Spray cooling has been a growing concern in the past few years. However, there were few researches about the numerical simulation of the outdoor space influenced by spray cooling, especially on the relationship between the temperature and its influencing factors, so the plan of spray cooling is still based on experience because of few theories. This shortage seriously limited the widespread of spray cooling. The model which describes the relationship between temperature and time is built up, to demonstrate the correctness of the model by regression analysis. Meanwhile, the relationship between humidity and temperature balance time, humidity and cooling rate and cooling were analyzed and plotted, and then the method of calculating the cooling range was offered. This model can be used to analyze the relationship between temperature and time, predict cooling range of different spray cooling device, provide appropriate methods for the selection of spray cooling device and spray cooling plan, and make a contribution to the popularization of spray cooling.
