Abstract

The existing rural houses in Chuzhou often lack scientific plan and design, and the impact of the continuous high temperature in summer lead to overheat on indoor environment has gradually become stronger. In order to solve this problem, This paper conducted field surveys and measurements on rural houses in Chuzhou. The survey results show that the rural houses in this area are mainly three-story buildings; the actual measurement results of typical houses show that the average temperature and average humidity of indoor and outdoor spaces are: 31.6 on the first floor. ℃, 76.1%, bedroom A on the second floor is 32.3℃, 73.2%, bedroom B is 32.3℃, 73.5%, on the third floor 33.9℃, 68.9%, outdoor 31.7℃, 74.7%. The indoor temperature during the day is lower than the outdoor temperature, and the indoor temperature at night is higher than the outdoor temperature. Numerical analysis of the factors that affect the indoor temperature at night. The most important factors are: first floor: east wall, south wall, north wall, roof; second floor A: west wall, south wall, east wall, outdoor; second floor B: East wall, roof, south wall, west wall, third floor: south wall, west wall, east wall, ground. Combining the spatial location, it can be found that the east wall, south wall, west wall, and floor slab have the greatest influence on indoor temperature. Based on the experimental results and local actual conditions, three optimization methods of roof, external wall and external shading are proposed.
