Improve The Indoor Thermal Environment Of Rural Residential Design And Research In Chongqing

With the launching of rural construction in full swing, rural housing have sprung up. As in the past for rural residential thermal environment and insufficient attention to energy conservation and rural economic levels of constraints, residential construction has not improved thermal performance, thermal insulation performance is still poor. Over the years, mainly focused on energy-saving urban housing, but involved the saving of rural housing is not much comfort laboratory thermal environment does not have many. People are indoors most of the time spent in the closed room, people living and working most of their time indoors, indoor environment and human closely. It has a direct impact on people's physical and mental health. Thermal environment refers to solar radiation, air temperature, surrounding surface temperature, relative humidity and air velocity and other physical factors acting on the composition of who's hot and cold affect the human being and a healthy environment. Therefore, improving the indoor thermal environment in rural areas of Chongqing has become the architect of the most urgent task.This thesis topics based on the indoor thermal environment studies, analyzing the thermal environment at home and abroad on the theory and literature, through a summary of the regional climate features in Chongqing and rural development history in order, to the back of the Rural Residential Investigation of indoor thermal environment provide a basis. In July 2009 to August 2009, and in February 2010 on the surrounding rural areas of Chongqing Banan District, University City, Yongchuan District, Bishan County, Tongliang area, Hechuan area, large enough so select a certain number of dwellings to Investigation of indoor thermal environment, through questionnaires, temperature, humidity testing, field mapping, etc., use of materials on their residential status, cooking energy use, habits, indoor thermal environment and air quality and energy use. Survey, the potential for urban housing energy conservation, energy consumption between different parts of significant differences, mainly due to regional differences and the impact of living pattern. Many factors affect the family energy consumption, including family income, demographic composition, housing costs and the impact of cooling methods on energy consumption significantly, construction and building use area's relatively small.Through statistical analysis of survey results, Chongqing summer afternoon until evening living room temperatures often exceeded 34℃, some as high as 39 ~ 40℃, in particular the continuous hot weather is difficult to sleep indoors at night. Residents generally reflect the indoor thermal environment is generally not good. Study found that poor indoor thermal environment, the main three reasons are hot in summer and cold in winter there is two sides of the conflict region, exists in the form of residential space ventilation design, thermal performance of external care less. To "identify problems - Analysis of the problem - to solve the problem" approach, for Chongqing's climate characteristics and regional culture, proposed to improve the indoor thermal environment of the two strategies.When the current design of residential building ventilation factor, accounting for less external structure, failed to make full use of natural climate resources. Resulting in rural areas of poor quality of indoor thermal environment. Effective strategies to improve the indoor thermal environment are: 1) to increase indoor ventilation 2) to improve the external structure; Chongqing hot and humid as in summer, you can increase the "drafts" to guide the air flow away indoor heat; and improve the external supporting structure, such as water saving design of the roof, wall insulation to improve the performance, appropriate shading mode, doors, windows and other energy-saving design.Finally, for the indoor thermal environment improvement in Housing case studies, select the research area of a typical rural house Yongchuan Unit, and use computer simulation software Ecotect their indoor thermal environment analysis. By improving the living room and master bedroom of the indoor ventilation and maintenance of the structure, calculate the heat on in the cold days and the temperature, humidity, structural heat gain and heat loss, compare the temperature before and after improvement, demonstrated two major design transformation strategy is correct and feasible .In this paper, low-cost energy-saving passive approach, try to design a means of beginning to improve with the building thermal environment, as far as possible avoid the use of active mechanical equipment or machinery and equipment used to reduce the time, so that the indoor thermal environment to achieve acceptable levels of people . To improve people's living quality, reduce building energy consumption and indoor thermal environment to promote sustainable development, have great significance. Hope that the Chongqing area of rural residential thermal comfort to provide reference.
