Abstract
In order to understand the thermal process of passive solar dormitories in highland areas, this paper establishes a heat transfer model for passive solar student dormitories and analyses the effects of convective heat transfer coefficient and thermal conductivity of their envelope surfaces on the heat storage, and then analyses the effects on indoor air temperature. The results show that increasing the convective heat transfer coefficient of the floor surface and the thermal conductivity of the floor can both increase the indoor air temperature. Once the thermal conductivity has been increased to 1.5 W/(m2·K), further improvements are no longer noticeable in terms of temperature increase. Increasing the convective heat transfer coefficient of the floor surface and the thermal conductivity of the floor both enhance the heat storage of the floor. When the thermal conductivity is less than 1.5 W/(m2·K), increasing the thermal conductivity has a greater impact on the heat storage of the floor, while increasing the convective heat transfer coefficient has a less obvious impact on the heat storage of the floor. This paper is a guide to optimizing the energy efficiency of passive solar buildings of the same type.
