Study on heat storage mechanism of building wall based on passive housing

Study on heat storage mechanism of building wall based on passive housing Building energy consumption has seriously affected the economic development of various countries. Through in-depth analysis of the basic characteristics of passive buildings in Germany, this paper establishes a building geometric model with traditional heat collecting wall rooms. By optimizing the heat transfer model and boundary conditions of the building, the thermal environment of the model under steady-state and transient conditions is simulated and analyzed respectively. The heat collection characteristics of the outer surface of the heat collection wall in winter are deeply discussed. The distribution characteristics of the temperature field and wind speed field of the vent and the room as well as the effects of the wall size parameters and the surface structure of the heat collection wall on the heat collection efficiency are compared. Through the test and analysis of the heat collection effect of passive buildings, it is proved that the structural technology studied in this paper has an obvious effect on architectural design and transformation, and has important application value. It provides a theoretical basis for the field test of transforming the existing passive solar house. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Asian Architecture and Building Engineering Taylor & Francis
