【摘要】 本文所完成的内容,是正在制定的国家标准《居住建筑节能设计标准》的一个组成部分,主要为严寒和寒冷地区关于建筑节能条文的编制,提供理论依据。本文针对我国严寒和寒冷地区要实现的第三部节能目标,分析了围护结构和供热系统应采取的节能措施,确定了围护结构和供热系统各自应该承担的节能比例。本文在对供热系统的节能潜力进行分析的基础上,根据目前我国锅炉、热网的现状和管理水平,提出了第三部节能时,锅炉年均运行效率及管网输送效率的限值。我国幅员辽阔,气候条件差异很大,为了使建筑热工设计与地区气候相适应,文中在分析严寒和寒冷地区采用新的分区方法后,各区域建筑物耗热量指标限值的基础上,采用正交试验法来确定实现第三步节能目标后多层建筑、小高层建筑、高层建筑和低层建筑各自的节能指标体系。最后通过能耗模拟,比较了动态计算方法和有效传热系数法的差别。更多还原

【Abstract】 Researches completed in this thesis are one part of Standards of Energy Conservation Design for Civil Buildings, which is a national standard that is being established. Contents of this thesis supply theoretical bases for establishing energy conservation citation in freezing areas.At the aim of the third step goal of energy conservation in the coldest region, this thesis analyzes the measures that should be taken in building envelope and heating system. This thesis ascertains the rate of energy conservation that building envelope and heating system should take respectively.Based on the analysis into energy conservation potential of heating system, and in the reference to the control level of domestic boilers and heat supply network, we put forward the limitation of boiler’s operating efficiency and network’s transfer efficiency in the third step energy conservation.Our country has a large territory and the weather varies observably. To make thermal design of building suit to the climate, this thesis gives a new method to partition the coldest zone and the limit of heat consumption indexes of each partition. Based on the researches above, after realizing the third step goal, we use orthogonal testing method to ascertain the limit of heat transfer coefficients of tier buildings, high rise buildings and low rise buildings. Finally through simulation of energy consumption, we analyze the difference between dynamic analysis method and the effective heat transfer coefficient method.更多还原
