Description
技术领域：Technical field:
本发明涉及一种实现太阳能光伏热利用与建筑空气热湿调节两种能源的耦合方法。The invention relates to a coupling method for realizing solar photovoltaic heat utilization and building air heat and humidity regulation.
背景技术：Background technique:
太阳能光伏发电技术在标准状况下，常用的硅太阳电池发电效率为12% ~17%，实际中发电效率仅10% ~15%。然而实验室中硅太阳能电池的最大效率可以高达31%左右，而温度是导致其发电效率大幅衰减的重要影响因素之一。太阳能电池的发电的过程是个放热过程，随着时间的积累，电池板的温度不断地升高，进而导致发电效率降低2%左右。太阳能电池板温度每升高1℃，开路电压则减小0. 4%，短路电流基本不变，则输出功率减小0. 4%。因此，对太阳能光伏电池冷却将提高其发电效率，而充分利用冷却下来的太阳能光伏热还可以提高整个系统的环保意义，使系统更加节能。Under standard conditions for solar photovoltaic power generation technology, the power generation efficiency of commonly used silicon solar cells is 12% to 17%, but the actual power generation efficiency is only 10% to 15%. However, the maximum efficiency of silicon solar cells in the laboratory can be as high as about 31%, and temperature is one of the important factors that lead to a significant decline in its power generation efficiency. The power generation process of solar cells is an exothermic process. With the accumulation of time, the temperature of the solar panels continues to rise, which in turn reduces the power generation efficiency by about 2%. Every time the temperature of the solar panel increases by 1°C, the open circuit voltage decreases by 0.4%, and the short-circuit current remains basically unchanged, the output power decreases by 0.4%. Therefore, cooling the solar photovoltaic cell will improve its power generation efficiency, and making full use of the cooled solar photovoltaic heat can also improve the environmental protection significance of the entire system and make the system more energy-saving.
随着经济发展和生活水平的提高，用于建筑空调系统中的能耗占总建筑能耗的比重逐年加大，不但给紧张的能源与环境问题施加压力，同时还加剧了电力供应的矛盾。传统的制冷系统中应用氟利昂做制冷工质，其破坏臭氧层，加速了环境恶化。在能源与环境问题日趋严重的情况下，制冷系统在建筑空调系统中的广泛应用与节能减排的政策背道而驰，这就需要有新的建筑空气热湿调节方法取代传统的制冷空调系统中的空气热湿调节方法。With economic development and improvement of living standards, the proportion of energy consumption used in building air-conditioning systems in total building energy consumption is increasing year by year, which not only puts pressure on tense energy and environmental issues, but also exacerbates the contradiction of power supply. Freon is used as the refrigerant in the traditional refrigeration system, which destroys the ozone layer and accelerates the deterioration of the environment. In the case of increasingly serious energy and environmental problems, the widespread application of refrigeration systems in building air-conditioning systems runs counter to the policy of energy conservation and emission reduction, which requires a new method of building air heat and humidity regulation to replace the air in traditional refrigeration and air-conditioning systems Method of heat and humidity regulation.
结合热力学第一定律，将太阳能光伏电池冷却系统与建筑空气热湿调节系统中的太阳能光伏热与空气热能、湿能做能源耦合，不但能够提高太阳能光伏电池发电效率，节约利用太阳能光伏热，还可以降低建筑能耗，将空气热湿调节系统简单化。Combined with the first law of thermodynamics, the energy coupling of solar photovoltaic heat, air heat and moisture in the solar photovoltaic cell cooling system and building air heat and humidity conditioning system can not only improve the power generation efficiency of solar photovoltaic cells, save the use of solar photovoltaic heat, but also It can reduce building energy consumption and simplify the air heat and humidity conditioning system.
