[Abstract]:The proportion of building energy consumption in the total social energy consumption in China is about 30%. The reasonable and full utilization of solar energy can reduce building energy consumption and reduce environmental pollution. It has become an industrial development focus and research hotspot in the field of building energy conservation and new energy utilization. In order to improve the comprehensive utilization efficiency of solar energy and promote the development of energy saving and emission reduction in China, it has broad market application prospect and popularizing value. It is necessary to study its system form, develop key engineering technology and analyze the economy of its popularization and application. Firstly, according to the design requirements of conventional electric load and winter heating load in the laboratory, and based on the analysis of the existing solar energy and heat supply system at home and abroad, a solar energy heat combined power supply system with a generating capacity of 7.56 kW is designed. In this paper, 36 new PVT cogeneration modules are designed, developed and processed, and their performance is tested, and a demonstration project of 7.56kW solar thermal power supply system is built. The construction and commissioning of the thermoelectric performance monitoring system of the project are completed. Thirdly, the cogeneration characteristics of the system in the heating season and transition season of the system in 2015 are tested, and the operating characteristics of the system are analyzed in detail according to the running data of the system. Finally, according to the solar photothermal test data and the photoelectricity theory calculation results, the technical economy analysis and the investment recovery period analysis of the demonstration project are completed, which provides a technical reference for the popularization and application of the technology. The demonstration project of solar energy and heat supply system in this study can accumulate 288MJ (equivalent to 9.8kgcec) heat and 30kWh electricity per day under the condition of sunny heating season. The average total power is 6 kW, the average heat collection efficiency is 23 and the photoelectric conversion efficiency is 15. The average daily accumulative total heating capacity is 320MJ (equivalent to 10.9kgceg / h, total generating capacity is 31kWhs), the average generating power is 6.2kW, the average heat collection efficiency is 28and the integrated photoelectric conversion efficiency is 150.The total fixed cost of the demonstration project is 118,200 yuan through technical and economic analysis. The operating cost of the system is 2336 yuan per year. Combined with the subsidy policy of solar photovoltaic power generation and the conversion of heating fees and heat energy to standard coal, the annual income of the project is 12,800 yuan, and the dynamic investment recovery period is 11.32 years. The total energy saving per year is 3.45 tons of standard coal.
