严寒地区农村住宅节能技术研究
发布时间：2019-05-12 08:53
【摘要】：我国村镇地区地广人多,建筑面积庞大,村镇建筑生活用能是村镇能源消费的主要构成部分。随着社会主义新农村建设战略发展的实施,农民条件的改善,大规模的农村住宅建设将消耗更多的能源。而我国当前农村对能源的开发和利用方式相对落后,能源浪费情况严重、利用率低。随着农村住宅的改建、扩建速度的逐年加快,对农民居住的条件改善的需求越来越迫切。但由于没有科学的设计依据,有些农村住房盲目地改建,造成多数农村住宅为能耗高、层次低的重复性住宅,造成能源、资源的大量浪费。本文即以此问题为切入点,通过对当前北方典型农村住宅进行调研,通过问卷调查、实际观察测绘、现场测试等方式,掌握农村住宅实际状况、能源的种类和使用情况及主要的采暖形式,并对这些方面存在的不利因素,提出相应的解决方案。并以其中严寒地区农村住宅为研究对象,对其外墙、地面、屋顶及外门等围护结构的传热系数进行了实地测试。进而根据严寒地区的气候特征,利用能耗模拟软件DeST-h模拟,研究严寒地区农房外围护结构对室内热环境与建筑能耗的影响。主要从朝向、外墙保温方式、外墙传热系数K值、外窗传热系数K值及地面、屋面保温措施等几个方面进行研究分析,分析各种措施在降低采暖能耗中的作用大小,为农村住宅新建、改造提供指导方向和具体措施。通过对当前严寒地区典型农村住宅的调研分析,掌握第一手资料,了解农村住宅现状、能源结构形式和利用情况及典型的采暖方式,并对这些方面存在的不利因素,提出相应的解决方案。对设计建造出舒适节能的宜居农村住宅,缓解我国能源紧缺状况有着重要的意义。
[Abstract]:There are many people in the villages and towns of our country, and the building area is huge. The energy consumption of the villages and towns is the main component of the energy consumption of the villages and towns. With the implementation of socialist new rural construction strategy and the improvement of farmers' conditions, large-scale rural housing construction will consume more energy. However, the current rural development and utilization of energy in China is relatively backward, energy waste is serious, and the utilization rate is low. With the reconstruction of rural housing and the acceleration of expansion rate year by year, the demand for the improvement of farmers' living conditions is becoming more and more urgent. However, because there is no scientific design basis, some rural houses are blindly rebuilt, resulting in the majority of rural housing for high energy consumption, low-level repetitive housing, resulting in a large amount of waste of energy and resources. This paper takes this problem as the starting point, through the investigation of the typical rural housing in the north, through the questionnaire investigation, the actual observation and mapping, the field test and so on, to grasp the actual situation of the rural housing. The types and uses of energy and the main heating forms are discussed, and the corresponding solutions are put forward for the unfavorable factors in these aspects. The heat transfer coefficient of the exterior wall, the ground, the roof and the outer door of the housing in the severe cold area was tested on the spot, and the heat transfer coefficient of the exterior wall, the ground, the roof and the outer door were tested. According to the climate characteristics of severe cold area, the influence of exterior protection structure of farm house on indoor thermal environment and building energy consumption was studied by using energy consumption simulation software DeST-h. Mainly from the orientation, external wall heat preservation mode, exterior wall heat transfer coefficient K value, exterior window heat transfer coefficient K value and floor, roof insulation measures, and so on, analyzed the role of various measures in reducing heating energy consumption. To provide guidance and specific measures for the construction and reconstruction of rural housing. Through the investigation and analysis of the typical rural housing in the severe cold area, we can master the first-hand data, understand the current situation of the rural housing, the form of energy structure and utilization and the typical heating mode, and make use of the unfavorable factors in these aspects. The corresponding solutions are put forward. It is of great significance to design and build comfortable and energy-saving rural housing and alleviate the shortage of energy in our country.
