【摘要】：工业建筑能耗在建筑能耗中占有相当大的比重,但长期以来,与民用建筑相比,工业建筑能耗没有得到应有的重视,随着我国制造业体量的不断增大和对节能减排要求的不断提高,工业建筑节能工作已势在必行。论文概述了绿色工业建筑的起源和发展,对比分析了国内外绿色建筑评价指标体系,并以能耗模拟软件eQUEST作为主要研究工具,建立了能够反映工业建筑特点的基准模型,对工业建筑常用的节能技术进行了比较研究。研究了寒冷地区节能技术对供暖能耗的影响。发现寒冷地区围护结构节能的重点应在屋面；室内设定温度和换气次数对建筑能耗影响较大,满足工艺生产和热舒适性条件下应该尽量降低设定温度和换气次数,但夏季应多利用夜间通风降低自然室温。论文还对高大空间不同供暖系统形式进行实测与经济性分析,得出燃气红外线辐射采暖是一种较为经济、有效的供暖形式,高大厂房应该积极采用。研究了夏热冬暖地区节能技术对空调能耗的影响。量化了室内设定温度、冷水机组COP、送风温度、大温差系统、水泵效率、变水量系统、冷却塔变速风机等技术措施对空调能耗的影响,并对工业建筑常采用的节能空调系统形式进行了分析。
[Abstract]:Industrial building energy consumption occupies a large proportion in building energy consumption, but for a long time, compared with civil building, industrial building energy consumption has not received due attention. With the increasing of our manufacturing industry and the increasing requirements of energy saving and emission reduction, it is imperative for industrial buildings to save energy. This paper summarizes the origin and development of green industrial buildings. Comparing and analyzing the evaluation index system of green building at home and abroad, and taking the energy consumption simulation software eQUEST as the main research tool, the benchmark model which can reflect the characteristics of industrial building is established. This paper makes a comparative study on the energy saving technology commonly used in industrial buildings, studies the influence of energy saving technology on heating energy consumption in cold regions, and finds out that the emphasis of energy saving of enclosure structure in cold areas should be on roof; Indoor temperature and air exchange times have a great impact on building energy consumption. To meet the requirements of process production and thermal comfort, the set temperature and the number of air exchange should be reduced as far as possible. However, night ventilation should be used to reduce the natural room temperature in summer. Different heating systems in large space are measured and economic analysis is carried out in this paper, and it is concluded that infrared radiation heating of gas is more economical. The effect of energy saving technology on air conditioning energy consumption in hot summer and warm winter area is studied. The indoor setting temperature, COP of chiller, air supply temperature and large temperature difference system are quantified. The effects of water pump efficiency, variable water flow system and cooling tower variable speed fan on the energy consumption of air conditioning system are analyzed, and the energy saving air conditioning system forms commonly used in industrial buildings are analyzed.
