【摘要】：进入新世纪以来,节能环保问题一直是人类社会头等问题之一,为了积极应对这一问题,国家在2012年印发节能减排“十二五”规划,以降低能耗,节约能源,创建节约友好型社会。而我国城市化发展迅速,我国每年城镇新建建筑的总面积在2020年前保持10亿平方米/年左右,建筑用能将会急剧增加,给国家节能减排政策的实施带来巨大的压力,其中,大型公共建筑是值得关注的,此类建筑只占城镇总建筑面积的6%左右,但其用电量很大,是住宅建筑用电量的10倍以上,因此公共建筑的节能的研究是工作的重点,而公共建筑热源形式的分析是关键。数据库管理系统是现代数据管理的高效工具,它能对大量信息数据进行很好的记录与管理,同时能进一步的分析与计算。公共建筑热源形式数据库的开发能较为合理的、全面的、集中式的管理公共建筑热源系统的信息,方便建筑能耗的统计及运营管理,同时能提供客观合理的系统运行能效、能耗、经济、节能和环保等方面的热源评价指标体系,有利于全面了解建筑热源信息,为制定能源政策、推进建筑节能工作打下了坚实的基础。本文以严寒地区沈阳作为热源系统研究对象,选择几个有代表性的公共建筑,采用调研实测、理论分析相结合的方法,对建筑物的实际热源系统参数,经济费用、建筑的基本信息做了详细记录,并用模糊数学和层次分析理论的基础上确定了热源系统在经济性、节能性、环境效益方面的评价方法。本文以MS Access 2003作为后台数据库,以Visual Basic 6.0为前端开发工具开发了严寒地区公共建筑热源形式管理系统。通过本数据库管理系统可以实现对建筑基本信息、建筑热源系统设计参数、建筑热源系统运行参数的录入和查询,对建筑物热源系统的经济性、节能性和环境效益方面的适宜性分析,并能选择不同热源进行横向适宜性分析,从而得出最优的热源系统方案,为建筑物的节能改造以及后建建筑物的热源系统使用提供了直观参照。
[Abstract]:Since entering the new century, the problem of energy saving and environmental protection has always been one of the top problems in human society. In order to actively deal with this problem, the state issued the 12th Five-Year Plan for Energy Saving and Emission reduction in 2012 in order to reduce energy consumption and save energy. Create a thrifty and friendly society. However, with the rapid development of urbanization in China, the total area of newly built buildings in cities and towns in China will be maintained at about 1 billion square meters per year before 2020, and the use of building energy will increase sharply, which will bring great pressure to the implementation of the national policy on energy conservation and emission reduction, among which, Large public buildings are worthy of attention. These buildings only account for about 6% of the total urban building area, but their electricity consumption is very large, which is more than 10 times that of residential buildings. Therefore, the research on energy conservation of public buildings is the focus of work. The analysis of heat source form of public buildings is the key. Database management system is an efficient tool for modern data management. It can record and manage a large number of information data, and can be further analyzed and calculated. The development of public building heat source database can be more reasonable, comprehensive and centralized to manage the information of public building heat source system, facilitate the statistics of building energy consumption and operation management, at the same time, it can provide objective and reasonable energy efficiency of system operation. The evaluation index system of energy consumption, economy, energy saving and environmental protection is beneficial to the comprehensive understanding of building heat source information, which lays a solid foundation for making energy policy and promoting building energy conservation work. This paper takes Shenyang as the research object of heat source system, selects several representative public buildings, adopts the method of surveying and measuring, combining the theory analysis, to the actual heat source system parameter of the building, the economic cost. The basic information of building is recorded in detail, and the evaluation method of heat source system in economy, energy saving and environment benefit is determined based on fuzzy mathematics and analytic hierarchy process theory. This paper takes MS Access 2003 as the background database and Visual Basic 6.0 as the front-end development tool to develop the heat source management system of public buildings in severe cold areas. Through the database management system, we can input and query the basic building information, the design parameters of the building heat source system, the operation parameters of the building heat source system, and the economy of the building heat source system. The suitability analysis of energy saving and environmental benefit, and can select different heat sources for lateral suitability analysis, thus the optimal heat source system scheme can be obtained. It provides an intuitionistic reference for energy saving reconstruction of buildings and the use of heat source system of the post-built buildings.
