通水屋面虽能实现屋面隔热,但不能满足利用太阳能为建筑供应热水的需求。本文在通水屋面构造设计的基础上,研制出1种新型低成本的太阳能集热、隔热及冷却屋面模块,并建造了太阳能集热屋面模块性能测试平台,通过不同模块对比测试方法,对所研制模块的集热量、集热效率及其隔热性能等进行了测试分析。通过测量集热模块在不同工况下的集热管进出口水温、流量以及环境温湿度、辐射强度、模块各构造层温度及传热热流等性能参数,获得了集热模块在不同工况下的集热量、集热效率、模块隔热性能等随时间的变化规律及其评价参数,分析了模块集热性能与辐射强度及流量之间的变化关系,对比分析了不同构造模式下集热模块的隔热性能及其变化特点,为其工程应用提供了基本的实验依据。本模块也为建筑屋面隔热、冷却及集热提供了1种低成本的构成模式,并为屋面冷却及太阳能集热提供了1种新的工程应用方法。
Although the water through the roof roof insulation, but can not meet the use of solar energy for the construction of hot water supply needs. Based on the structural design of water-through roof, a new type of low-cost solar collector, insulation and cooling roof module was developed and the solar thermal collector roofing module performance test platform was built. Through the comparison test of different modules, The developed modules of the collector heat collection efficiency and thermal insulation properties were tested and analyzed. By measuring the inlet and outlet water temperature, flow rate, ambient temperature and humidity, radiation intensity, temperature of each structural layer of the module and the heat transfer heat flux of the collector module under different operating conditions, the performance of the collector module under different operating conditions The relationship between the collector’s thermal performance and the radiation intensity and the flow rate was analyzed, and the relationship between the collector’s heat collection efficiency and the module insulation performance under different construction modes Thermal properties and the characteristics of its changes, for its engineering application provides a basic experimental basis. The module also provides a low-cost mode of construction for building roof insulation, cooling and heat collection, and provides a new engineering application method for roof cooling and solar heat collection.
