【摘要】：中國的能源環(huán)境問題已經(jīng)日益嚴重。我國化石能源存量少消耗大,能源使用是導(dǎo)致大氣污染、酸雨等環(huán)境問題的主要因素。我國是產(chǎn)煤大國,也是耗煤大國。特別是北方地區(qū),冬季使用集中鍋爐燃煤供暖煤耗逐年增加,引發(fā)多種污染。引入地?zé)崮�、太陽能、風(fēng)能等自然資源,改善能源消費結(jié)構(gòu),利用可再生清潔能源技術(shù),在滿足冬季建筑供暖高負荷需求的同時,減少對化石能源的消耗,降低污染物排放,這對于能源與經(jīng)濟可持續(xù)發(fā)展和改善日益惡化的環(huán)境問題具有深遠意義。本文圍繞這一問題展開深入研究,提出在北方地區(qū)實行地源熱泵與太陽能、風(fēng)能互補利用的可再生清潔能源供暖技術(shù),在對互補利用系統(tǒng)設(shè)計的基礎(chǔ)上,構(gòu)建模型,運用動靜態(tài)相結(jié)合的方法,定量分析互補利用系統(tǒng)的能源、環(huán)境、技術(shù)經(jīng)濟和綜合效益,結(jié)合對社會效益的定性分析,形成互補利用系統(tǒng)效益分析的整體框架。通過實證分析,具體測算北京某小區(qū)不同型號住宅應(yīng)用互補利用系統(tǒng)進行冬季供暖的節(jié)能減排效益以及用戶投資互補利用系統(tǒng)的技術(shù)經(jīng)濟效益,結(jié)果表明互補利用系統(tǒng)相比于燃煤鍋爐供熱具有顯著的能源環(huán)境效益,相比于地源熱泵單一供熱系統(tǒng)在各個角度具有明顯的改善效果,并預(yù)測若在北京地區(qū)推廣該應(yīng)用,對于“十二五”規(guī)劃任務(wù)貢獻力度大,為政府制定宏觀政策以鼓勵該技術(shù)的應(yīng)用提供指導(dǎo),同時幫助用戶根據(jù)自身情況進行住宅選型。在肯定互補利用系統(tǒng)的現(xiàn)實意義后,進一步深入研究互補利用系統(tǒng)效益的因素敏感性,結(jié)果表明熱泵機組性能系數(shù)、燃煤發(fā)電占比和分時電價峰谷比對于互補利用系統(tǒng)效益影響顯著,為政府在制定鼓勵互補利用系統(tǒng)政策方面提供支持。國家和社會應(yīng)該對可再生能源互補利用技術(shù)給與更多的重視。
[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.
