辐射供冷具有高舒适性、节能、无噪音及室内温度分布均匀等优点,在凉爽干燥的欧洲应用广泛。在湿热的中国大陆地区,其推广应用由于结露及换热量不足的原因受到较大限制。为了了解毛细管辐射供冷在高温高热地区的使用性能,搭建了毛细管辐射供冷测试实验台,研究了毛细管辐射供冷末端的换热特性,并采用可视化的研究方法分析了毛细管辐射供冷末端表面的结露特性,并提出了以过冷度为指标的运行策略,避免毛细管辐射供冷末端结露的产生。
Radiant cooling has the advantages of high comfort, energy saving, no noise and even indoor temperature distribution and is widely used in cool and dry Europe. In hot and humid areas of China, its application is limited due to the lack of condensation and heat exchange. In order to understand the performance of capillary radiant cooling in high temperature and high heat area, a capillary radiating cooling test bench was set up to study the heat transfer characteristics of the capillary radiation cooling end. The visualization of the capillary radiation cooling end surface The condensation strategy was proposed and the operation strategy based on the subcooling degree was put forward to avoid the condensation at the end of capillary tube cooling.
