Water pipes roof can realize the thermal insulation, but it is unable to supply hot water to buildings using solar energy. Based on the structure design of water pipes roof, the paper developed a new type of roof module that integrates solar energy collection, insulation and cooling at low cost, and constructed the experimental platform for testing the solar collection roof module. By means of a comparison test between different modules, the parameters of the developed module such as heat-collecting capacity, heat-collecting efficiency and thermal isolation performance were tested and analyzed. By measuring the performance parameters of the heat-collecting module in different working conditions, such as water temperature and flow of inlet and outlet of collector tubes, ambient temperature and relative humidity, radiation intensity, temperature at each constructing layer of module and heat flow in heat transfer, we found how the heat-collecting capacity, heat-collecting efficiency and thermal isolation performance of heat-collecting module varied over time in different working conditions, analyzed the relation of solar heat-collecting performance of module with radiation intensity and flow, and compared the thermal isolation performance of heat-collecting module with different constructing modules and its variation law. The findings provide an essential experimental basis for its application in engineering. The module also provides a low-cost construction mode for insulation, cooling and heat collection of building roof, and a new application method in engineering for roof cooling and solar collection.
