【摘要】：中国的能源环境问题已经日益严重。我国化石能源存量少消耗大,能源使用是导致大气污染、酸雨等环境问题的主要因素。我国是产煤大国,也是耗煤大国。特别是北方地区,冬季使用集中锅炉燃煤供暖煤耗逐年增加,引发多种污染。引入地热能、太阳能、风能等自然资源,改善能源消费结构,利用可再生清洁能源技术,在满足冬季建筑供暖高负荷需求的同时,减少对化石能源的消耗,降低污染物排放,这对于能源与经济可持续发展和改善日益恶化的环境问题具有深远意义。本文围绕这一问题展开深入研究,提出在北方地区实行地源热泵与太阳能、风能互补利用的可再生清洁能源供暖技术,在对互补利用系统设计的基础上,构建模型,运用动静态相结合的方法,定量分析互补利用系统的能源、环境、技术经济和综合效益,结合对社会效益的定性分析,形成互补利用系统效益分析的整体框架。通过实证分析,具体测算北京某小区不同型号住宅应用互补利用系统进行冬季供暖的节能减排效益以及用户投资互补利用系统的技术经济效益,结果表明互补利用系统相比于燃煤锅炉供热具有显著的能源环境效益,相比于地源热泵单一供热系统在各个角度具有明显的改善效果,并预测若在北京地区推广该应用,对于“十二五”规划任务贡献力度大,为政府制定宏观政策以鼓励该技术的应用提供指导,同时帮助用户根据自身情况进行住宅选型。在肯定互补利用系统的现实意义后,进一步深入研究互补利用系统效益的因素敏感性,结果表明热泵机组性能系数、燃煤发电占比和分时电价峰谷比对于互补利用系统效益影响显著,为政府在制定鼓励互补利用系统政策方面提供支持。国家和社会应该对可再生能源互补利用技术给与更多的重视。
[Abstract]:China's energy and environmental problems have become increasingly serious. China's fossil energy stock is less consumed and energy use is the main cause of environmental problems such as air pollution acid rain and so on. China is a big coal-producing country and also a big coal-consuming country. Especially in the northern region, coal consumption of central boiler for heating in winter increases year by year, causing many kinds of pollution. Introducing geothermal energy, solar energy, wind energy and other natural resources, improving the energy consumption structure, utilizing renewable clean energy technology, while meeting the high demand for heating in winter, reducing the consumption of fossil energy and reducing the emission of pollutants. This is of great significance to the sustainable development of energy and economy and to the improvement of worsening environmental problems. This paper focuses on this problem and puts forward the renewable clean energy heating technology based on the complementary utilization of ground-source heat pump, solar energy and wind energy in the northern region. Based on the design of complementary utilization system, the model is constructed. By using the method of dynamic and static analysis, this paper analyzes quantitatively the energy, environment, technology economy and comprehensive benefit of the complementary utilization system, and combines the qualitative analysis of the social benefit to form the whole frame of the benefit analysis of the complementary utilization system. Through empirical analysis, the energy saving and emission reduction benefits of different types of residential buildings in a residential district in Beijing in winter heating and the technical and economic benefits of complementary utilization system of users' investment are calculated. The results show that the complementary utilization system has significant energy and environmental benefits compared with the coal-fired boiler heating system, and has obvious improvement effect compared with the ground-source heat pump single heating system, and it is predicted that if the application is popularized in Beijing area, It makes great contribution to the 12th Five-Year Plan, and provides guidance for the government to formulate macro policies to encourage the application of the technology, and also helps the users to choose their houses according to their own conditions. After confirming the practical significance of complementary utilization system, the factor sensitivity of complementary utilization system benefit is further studied. The result shows that the performance coefficient of heat pump unit is obtained. The ratio of coal-fired power generation and the peak-valley ratio of time-sharing electricity have a significant impact on the benefit of complementary utilization system, which provides support for the government in formulating policies to encourage complementary utilization system. The country and society should pay more attention to the technology of complementary use of renewable energy.
