At present, the rural population of China is large. The rural population accounts for about 50% of the total population in Heilongjiang Province, which is located in cold region. The winter is cold in servere cold region, for example, the average outdoor temperature in winter is about -25°C in Daqing which is located in Heilongjiang Province, the indoor residential thermal environment is poor, people living there are uncomfortable. The existing rural residential building was researched in Daqing of Heilongjiang and the study of the indoor thermal environment was carried out. In this paper, the numerical simulation method is used to study the changes of indoor temperature field before and after adopting the wall insulation of existing house. The results show that the thermal environment of the existing rural house without wall insulation cannot satisfy the requirements of human comfort, and the bedroom temperature is about 15°C, and the temperature of the entrance hall is about 11°C. However, the insulation of the building envelope has an obvious effect on the indoor thermal environment, and the temperature of the bedroom and the entrance hall increase about 5°C and 3°C with wall insulation, respectively.
