Study On Energy Saving Principle Application Of Cavity Construction And Design Of Building Of Architectural Skin In Western Solar Enrichment Area

At present,in the western solar energy-enriched areas,the heating energy consumption of the buildings accounts for a large part of the total energy consumption.Therefore,solving the energy consumption problem of heating is the most important issue.The solar energy resources in this region are extremely rich.By increasing the use of solar energy and reducing the heat loss of the envelope structure,the energy consumption of heating can be effectively reduced.Therefore,the design of building skin is a key link that affects building energy consumption.As the epidermis evolves from a single structure to a composite structure,cavity construction is a strategy for tissue epidermis,and it has great potential for heat-accumulation,heat-storage and insulation properties.This paper takes the heating building in the solar energy-enriched area in western China as the research object.In the trend of the composite evolution of the commonly used epidermal materials,there are a large number of cavities in the epidermis structure.Based on the insufficiency of solar energy utilization,the first use of solar energy is The heat transfer process in the cavity structure and its basic principle are analyzed.The role of the cavity is analyzed in the heat buffering and slow release.The application experience of the solar heat utilization principle in the cavity structure is analyzed,including the heat accumulation The principle of thermal process is analyzed between hot wall,solar wall and sunlight,and its advantages are utilized.The main points of structural optimization are summed up,including the setting of the heat collecting surface,the setting of the heat storage body,the application of heat convection and the heat preservation measures;Then based on the optimization of function and scale and the optimization requirements of structure and shape,combined with the analysis of the cavity configuration in the existing examples,four cavity design strategies are summarized,including cavity cellization,cavity profile optimization,Additional sun room and composite heat storage;Finally,according to the design flow from the status quo to the principle and strategy,through three typical workers Structural design example building skin cavity,and its shape to be integrated thermal performance,the thermal analysis procedure,to solve the energy efficient building construction west solar enriched epidermal cavity area defects.
