【摘要】：建立了闭式热源塔的数学模型,利用MATLAB自编程序,实现了对喷淋工况下热源塔的数值模拟,并将计算结果与实验结果进行了比较。利用程序得到了喷淋工况下的闭式热源塔内喷淋溶液、载热流体、空气焓值的分布,结果表明:塔内空气焓值呈线性分布,翅片换热器上半部分换热效果比下半部分好,塔的中部位置附近最先出现结霜现象,空气干球温度高于5.1℃,相对湿度高于75%,闭式热源塔热泵系统没有结霜风险,可以停止喷淋泵,有助减少热泵系统的运行能耗。
[Abstract]:The mathematical model of the closed heat source tower is established, and the numerical simulation of the heat source tower under spray condition is realized by using MATLAB program, and the calculated results are compared with the experimental results. The distribution of spray solution, carrier heat fluid and air enthalpy in the closed heat source tower under spray condition is obtained by using the program. The results show that the air enthalpy in the tower is linearly distributed, and the heat transfer effect of the upper half of the finned heat exchanger is better than that of the lower half. The frosting phenomenon occurs first near the middle position of the tower. The air dry ball temperature is higher than 5.1 鈩，
