【摘要】：太陽能是一種清潔再生能源，它具有取材容易、成本較低的優(yōu)點，所以越來越多的受到大家的關(guān)心。近年來，隨著人們對環(huán)境問題認識的不斷深入，有越來越多的人關(guān)注太陽能的利用。太陽能，作為房屋建筑集中熱水系統(tǒng)的主要熱源，可減少能源與資源的消耗，減少二氧化碳對空氣的污染。但是，太陽能裝置在不同地域的地理氣候條件下存在著因地制宜的問題。所以，住宅建筑太陽能集中熱水系統(tǒng)在西安地區(qū)乃至整個西北地區(qū)的研究有著重要的現(xiàn)實意義。 首先，作者對太陽能熱水系統(tǒng)在住宅建筑中的應用進行了研究，分析了不同太陽能系統(tǒng)的原理構(gòu)成及優(yōu)缺點，同時對系統(tǒng)的主要設備進行了逐一分析、優(yōu)化，對整個系統(tǒng)的設計流程進行了計算分析和總結(jié)歸納。 其次，筆者對西安地區(qū)的住宅建筑特點和當?shù)貧庀筚Y料進行了分析計算，分析結(jié)果表明西安市地區(qū)太陽能資源較豐富，太陽能輻照量全年分布較均勻，完全可以滿足太陽能熱水系統(tǒng)方案在西安地區(qū)使用的需要。 最后，根據(jù)研究成果，本文以西安地區(qū)一個典型住宅小區(qū)為實例進行了太陽能熱水系統(tǒng)設計，同時對該系統(tǒng)做了技術(shù)經(jīng)濟分析。太陽能熱水系統(tǒng)設計與建筑設計同步，采用與建筑一體化的形式。集熱器選擇了CPC熱管式真空集熱器。將其安裝在屋頂上，通過方案比較后，確定太陽能熱水系統(tǒng)采用集中集熱——集中儲能的形式。本系統(tǒng)同時采用了動力循環(huán)方式，將水箱放在地下室的機房內(nèi)，解決了自然循環(huán)產(chǎn)生的一些問題。從分析結(jié)果看，集中集熱系統(tǒng)的每戶投資與其他家用熱水器的每戶的投資相差不大。對太陽能系統(tǒng)進行節(jié)能效益分析后，發(fā)現(xiàn)太陽能系統(tǒng)在減少二氧化碳排放，保護環(huán)境方面具有積極的意義。
[Abstract]:Solar energy is a kind of clean and renewable energy, it has the advantages of easy to use materials and low cost, so more and more attention is paid to it.In recent years, with the deepening understanding of environmental issues, more and more people pay attention to the use of solar energy.Solar energy, as the main heat source of concentrated hot water system in buildings, can reduce the consumption of energy and resources, and reduce the air pollution caused by carbon dioxide.However, solar energy devices in different geographical and climatic conditions exist in response to local conditions.Therefore, the study of solar concentrated hot water system in residential buildings in Xi'an and even the whole northwest area has important practical significance.First of all, the author studies the application of solar water heating system in residential buildings, analyzes the principle structure, advantages and disadvantages of different solar energy systems, and analyzes the main equipment of the system one by one.The design process of the whole system is analyzed and summarized.Secondly, the characteristics of residential buildings and local meteorological data in Xi'an are analyzed and calculated. The results show that the solar energy resources in Xi'an are abundant, and the solar radiation is distributed evenly throughout the year.It can fully meet the needs of solar water heating system in Xi'an area.Finally, according to the research results, this paper takes a typical residential district in Xi'an area as an example to design a solar water heating system, and makes a technical and economic analysis of the system at the same time.Solar water heating system design and architectural design synchronization, using the form of integration with the building.The collector selects CPC heat pipe vacuum collector.The solar hot water system is determined to adopt the form of centralized heat collection and concentrated energy storage after the comparison of the schemes and the installation of the solar water system on the roof.At the same time, the system adopts the power cycle mode and puts the water tank in the computer room of the basement to solve some problems caused by the natural circulation.According to the analysis results, the investment of each household of centralized heating system is not different from that of other household water heaters.After analyzing the energy saving benefit of solar energy system, it is found that solar energy system has positive significance in reducing carbon dioxide emission and protecting environment.
