【摘要】：随着绿色建筑和节能建筑的提出，太阳能作为一种新型能源在建筑的应用比例越来越高。本论文主要从建筑中太阳能热水应用这方面出发，结合具体工程实例阐述了我国现有建筑集中式和分散式热水系统的现状和面临的具体问题，并且针对该现状提出了太阳能热水系统在建筑中的改良和优化建议。以真正实现建设低碳节能的绿色建筑的终极目标。本文的主要研究成果包括以下几个方面： 1.在集中式和分散式太阳能热水系统技术的基础上提出了优势互补的“分散---集中式’模型，该模型可以很好的解决高层或者超高层的建筑均摊屋面小太阳能集热面不够的问题。南面的的住户选用分散式，北面的住户选用集中式热水系统。 2.针对我国太阳能热水系统的现状，提出了适合我国现阶段的“多层次太阳能建筑”，以适应不同人们的生活需求，加快太阳能一体化的发展。同时通过对实际工程的对比研究得出：在一体化的过程中，阳面的建筑的优先选用集热器和阳台、墙体结合，阴面的建筑选用集热器与屋面的结合。 3.通过对目前现有集热器效率的分析对比，提出了“追踪式集热器”概念，利用光感技术，使得太阳能集热器的集热面跟随太阳的移动和转动，，始终保持集热面与最强光线垂直,大大提高了集热器的效率。 4.结合具体的工程实例来进一步论证该模型和成果，实施了位于西安市西咸新区的沣东新城太阳能热水系统与建筑中的完美结合。形成了不同尺度、不同模式的系统的实践体系。我国太阳能在建筑中的应用正在历经高速发展，目前国家和各地方政府都已经出台了相关规范和措施，确保我国太阳能热水在建筑中形成合理科学的理论框架和方法体系。建立符合我国现阶段的太阳能热水系统。本论文为建筑中的太阳能人水系统提供了决策、实施和管理依据和参考，促进了我国建设环境友好型低碳节能社会事业的发展。
[Abstract]:With the development of green buildings and energy - saving buildings , the proportion of solar energy as a new type of energy in building is becoming higher and higher . In this paper , based on the application of solar hot water in building , the present situation and concrete problems of the centralized and decentralized hot water systems in our country are described .

1 . Based on the centralized and decentralized solar hot water system technology , a " decentralized - centralized " model with complementary advantages is proposed . The model can solve the problem of insufficient hot surface of the small solar heat collection in the high - rise or super - high - rise buildings . The households in the south are distributed , and the north - facing households adopt the centralized hot water system . 2 . Aiming at the present situation of solar water heating system in China , this paper puts forward a multi - level solar building suitable for the present stage of our country to meet the needs of different people and accelerate the development of solar energy integration .

3 . Through the analysis and comparison of the existing heat collector efficiency , the concept of " tracking heat collector " is put forward , and the light sensing technology is used to make the heat collecting surface of the solar heat collector follow the movement and rotation of the sun , so that the heat collecting surface is always perpendicular to the strongest light rays , so that the efficiency of the heat collector is greatly improved .

4 . Combining the concrete engineering examples to further demonstrate the model and the results , the perfect combination of the solar hot water system and the building in Xianyang New Area , Xi ' an , is implemented . The practical system of the system with different scales and different modes is formed .

The application of solar energy in buildings is developing at high speed . At present , the national and local governments have issued relevant codes and measures to ensure that our country ' s solar hot water forms a reasonable scientific theoretical framework and method system in the building . This paper provides the decision , implementation and management basis and reference for the solar water system in the building , and promotes the development of China ' s environment - friendly low - carbon energy - saving social undertakings .
