Application Of Vertical Solar Chimney Integrated With Temporary Panel House

The proportion of building energy consumption in our country can not be underestimated.With the development of infrastructure construction,the application of temporary buildings is also increasing,temporary shelters for natural disasters,temporary schools,temporary canteens,and temporary hospitals.Temporary Board housing functions continue to enrich,there is a growing concern about its energy consumption.In this paper,the solar chimney is designed to meet the building integration function,and the solar energy is used to strengthen the natural ventilation so as to reduce the energy consumption and improve the comfort of the human body.Therefore,for the purpose of energy-saving performance and comfort of the temporary building,the following measures are proposed:combining solar chimney technology in the temporary building,embodying the building integration technology,and utilizing the thermal pressure effect to strengthen the natural ventilation,instead of mechanical ventilation energy consumption and passive cooling and passive heating to save energy consumption of air conditioning,reduce energy consumption of board room,improve human comfort;The temperature and velocity of indoor air were calculated by building simulation software Airpak and solar chimney,and the comfort degree of human body was compared If it is not satisfied,it will be treated under the condition of air conditioning.OpenStudio is used as a test-bed for the combination of solar chimney and temporary panel house,and the system is optimized to minimize the energy consumption To verify the feasibility of the temporary building combined with solar chimney as a simulation system in hot summer and cold winter area,based on the zero equation model,a building integration system of the temporary building combined with solar chimney is constructed,the energy consumption,ambient temperature,flow field and wind velocity,PMV(Predicted Mean Vote)and PPD((Predicted Percentage of Dissatisfied)of the system were evaluated,the environmental temperature,flow velocity,PMV and PPD were used to evaluate the energysaving performance qualitatively by AHP.The results show that the indoor thermal environment of the temporary panel building with solar chimney can meet the requirements of human thermal comfort.The maximum reduction of PPD is 43.7%in winter and 56.2%in summer,and the temporary building has better energy-saving performance,the annual energy saving rate can reach 24.3%,which has a good reference value for improving the thermal environment of temporary buildings and reaching peak carbon.
