【摘要】：随着社会经济的快速发展和居民生活质量的不断提升,人们对居住建筑内的环境要求也越来越高,同时亦增大了对新型大功率照明设备及家电设备的使用,这对住宅建筑采暖和空调的能耗产生了很大的影响。住宅建筑室内散热量不仅对热环境有着很大的影响,同时对住宅建筑的能耗变化也起着重要作用。鉴于此,对当今住宅建筑内热源散热量调查研究具有重要的研究价值和现实意义。本文通过对住宅建筑围护结构和窗户的发展变化进行分析总结,得出随着此二者逐年发展间接的使住宅建筑内热源散热量有一定增加。同时由于人们的生活水平提高,各类家电的使用,使内热源散热量自身也有了很大程度的提升。对西北地区住宅建筑进行问卷调查,获得内热源散热量的相关数据,依据数理统计的方法,分析所得数据的可信度和有效度,并在此基础之上对数据分析得到西北地区城市和新农村住宅建筑内热源散热量动态分布与指标值。对各功能房间的散热量指标进行了相应的比较,且对影响内热源散热量的各因素进行分析。最终得到以下结论:(1)通过比较近年来住宅建筑的住房面积、家电设备和人民生活水平的变化情况可知,随着社会和技术的进步,不论是住宅建筑内热源散热量本身,还是影响内热源散热量的因素都已发生了很大的改变。(2)获得了西北地区城市与新农村住宅建筑内热源散热量的动态分布,在07:00-08:00、11:00-12:00、17:00-18:00和19:00-23:00这四个时段内城市建筑客厅和厨房的内热源散热量较高,新农村中餐厅和客厅的内热源散热量较高。(3)城市厨房和卧室的内热源散热量比例各约占30%,客厅与卫生间的内热源散热量比例各约占20%。新农村卧室的内热源散热量比例约占30%,客厅、厨房和卫生间的内热源散热量比例各约占20%。(4)通过对问卷数据的统计和分析,获得城市和新农村住宅建筑内热源散热量数值大约为标准的2.4倍。由于建筑面积的原因,使得西北地区城市住宅建筑内热源散热量指标比标准值增加了约20%,新农村内热源散热量指标则仅增加了约3%。(5)城市客厅、厨房和卫生间的内热源散热量指标值大于新农村。人员对散热量有着直接影响。随着建筑面积的增加城市和新农村的内热源散热量指标是逐渐降低的。年收入水平大于12万元后,住宅建筑内热源散热量基本稳定在4.0kWh。
[Abstract]:With the rapid development of social economy and the continuous improvement of the quality of life of the residents, the environmental requirements of residential buildings are becoming higher and higher. At the same time, the use of new high-power lighting equipment and household appliances has also been increased. This has had a great impact on the energy consumption of heating and air conditioning in residential buildings. Indoor heat dissipation of residential buildings not only has a great impact on the thermal environment, but also plays an important role in the change of energy consumption of residential buildings. In view of this, it has important research value and practical significance for the investigation and research of heat source heat emission in residential buildings. Based on the analysis and summary of the development of the envelope structure and windows of residential buildings, it is concluded that with the development of both of them year by year, the heat loss in residential buildings can be increased to a certain extent. At the same time, due to the improvement of people's living standard and the use of all kinds of household appliances, the internal heat source itself has been greatly improved. A questionnaire survey was conducted on residential buildings in Northwest China to obtain the relevant data of heat loss from internal heat source. According to the method of mathematical statistics, the reliability and validity of the data were analyzed. On this basis, the dynamic distribution and index value of heat source heat emission in urban and new rural residential buildings in Northwest China are obtained by analyzing the data. The heat dissipation indexes of each functional room were compared and the factors affecting the internal heat source heat loss were analyzed. Finally, the following conclusions are obtained: (1) by comparing the changes of housing area, household appliances and people's living standard in recent years, we can see that with the development of society and technology, whether it is the heat source of the residential building itself, The factors that affect the heat dissipation of internal heat source have changed greatly. (2) the dynamic distribution of heat source heat emission in urban and new rural residential buildings in Northwest China has been obtained. In the four periods of 07: 00-0800: 11: 00-12: 00, 17: 00-18: 00 and 19: 00-23: 00, the inner heat source of the living room and kitchen in urban buildings is relatively high. The new rural Chinese restaurant and living room internal heat source heat emission is higher. (3) the city kitchen and the bedroom internal heat source heat dissipation proportion each about 30%, the living room and the bathroom internal heat source heat dissipation proportion each about 20. The proportion of internal heat source heat emission in new rural bedrooms is about 30, and the proportion of internal heat emission in living room, kitchen and bathroom is about 20. (4) through the statistics and analysis of the questionnaire data, The heat emission of urban and new rural residential buildings is about 2.4 times of the standard. Because of the construction area, the heat emission index of urban residential buildings in northwest China has increased by about 20 percent over the standard value, while the heat emission index of new rural areas has only increased by about 3 percent. (5) Urban living rooms. The inner heat source of kitchen and bathroom is larger than the new countryside. Personnel have a direct impact on heat dissipation. With the increase of the building area, the internal heat emission index of urban and new countryside is decreasing gradually. After the annual income level is more than 120000 yuan, the heat source heat dissipation inside the residential building is basically stable at 4.0 kWh.
