【摘要】：根据严寒地区建筑供热系统能源优化配置及梯级利用的研究目标,对在建筑供暖规划中采用太阳能与常规能源联合供暖方式进行研究。本文首先了解当前世界能源现状及发展趋势,对国内外太阳能供暖情况及居住区规划节能设计理论基础加以认识。随后以规划居住区作为集中供热的研究基础,来分析规划设计中容积率、建筑选址、日照、避风、规划布局、住宅间距、建筑方位朝向、建筑体型系数以及规划热源形式的选择等方面的合理选择对规划居住区内建筑节能的重要性,并通过以上因素来分析规划居住区内给建筑采暖负荷带来的影响。再利用DeST模拟软件对规划区内的底层建筑(别墅型建筑)、多层建筑及不同层数的高层建筑进行了全年动态负荷的模拟计算,得到各类别住宅建筑采暖季的逐时负荷,为后文的研究提供了基础数据,以便对各类住宅建筑的太阳能保证率研究分析。接着对太阳能集热器的集热量进行计算,集热器集热量的多少主要与集热器的类型、集热器的布置位置及布置面积有关。本文选取的是平板型太阳能集热器,布置位置分为在南向外墙上、屋顶上、南向外墙和屋顶上同时布置三种情况,求得每一种情况单位面积的集热量。通过对规划居住区内不同类别住宅建筑的冬季采暖能耗以及其不同位置布置太阳能集热器所集热量进行研究分析,进而得出每一种情况冬季采暖中利用太阳能的保证率。最后过沈阳某规划居住区的设计方案来分析在冬季采暖中此规划区利用太阳能的保证率。
[Abstract]:According to the research goal of energy optimization and cascade utilization of building heating system in severe cold area, the combined heating mode of solar energy and conventional energy in building heating planning is studied. In this paper, the current energy situation and development trend in the world are first understood, and the theoretical basis of solar heating and energy saving design for residential area planning at home and abroad is discussed. Then, taking the planning residential area as the research basis of central heating, to analyze the volume ratio, building location, sunshine, wind shelter, planning layout, residential spacing, building orientation in planning and design, The importance of reasonable selection of building shape coefficient and planning heat source form for building energy saving in planning residential area is discussed, and the influence of planning residential area on building heating load is analyzed through the above factors. Then the dynamic load of the bottom building (villa type building), multi-story building and high-rise building with different storeys in the planning area is simulated by DeST software, and the hourly load of each kind of residential building during heating season is obtained. This paper provides the basic data for the following research, in order to study and analyze the solar energy guarantee rate of all kinds of residential buildings. Then the heat collection of solar collector is calculated. The amount of heat collection is mainly related to the type of collector, the location and area of solar collector. In this paper, the plate solar collector is selected. The location of the solar collector is divided into three types: the south outer wall, the roof, the south outer wall and the roof, and the heat collection per unit area is obtained in each case. By analyzing the energy consumption of heating in winter of different types of residential buildings in the planning area and the heat collected by solar collectors arranged in different locations, the guarantee rate of solar energy utilization in winter heating in each case is obtained. Finally, the paper analyzes the guarantee rate of solar energy utilization in the winter heating by the design scheme of a planned residential area in Shenyang.
