Integrated design of solar photovoltaic photothermal building based on micro heat pipe array

Aiming at the problems of overheating technology bottleneck and photovoltaic heat wave cost of solar photovoltaic cell modules, this paper carries out the research and design of solar photovoltaic photothermal building integration based on micro heat pipe array. Using the high-efficiency heat conduction technology of micro heat pipe array, the waste heat and waste heat generated by photovoltaic cells are used to generate building hot water, which not only improves the efficiency of photovoltaic cells, but also provides heating and hot water for buildings. The cooling and heat transfer characteristics of micro heat pipe array are analyzed and studied from the perspective of heat transfer and flow, and the theoretical model of heat transfer and flow characteristics of micro heat pipe array is established, An experimental platform for flow and heat transfer characteristics of micro heat pipe array was built. Study the integrated system model of solar photovoltaic photothermal building, build the photovoltaic cell module based on micro heat pipe array, design the integrated solar cogeneration unit, optimize the system energy control and operation management scheduling scheme, and establish the system microgrid monitoring and control system to provide technical support for the integration of solar energy and building in Tibet, On the basis of energy conservation and emission reduction, give full play to the role of industry driving and industry leading, so as to provide reference for realizing the goal of carbon peak and carbon neutralization.
