[Abstract]:In severe cold area, there are some problems in the building of burning Kang in cold area, such as poor smoke discharge, low indoor temperature in winter, serious indoor air pollution, etc. In this paper, an intermittent solar energy heating system with hot air is put forward in this paper. The system is based on solar energy and shallow soil can be used in the cold areas of towns and villages, fully using solar energy technology to improve the indoor temperature of the Kang building, while using the ground-wind technology preliminary preheating or pre-cooling outdoor fresh air, To achieve the purpose of energy saving and improving indoor air quality. In view of burning Kang buildings in villages and towns in severe cold area, a kind of solar heating system with hot wind is put forward, which can make full use of the hot pressing function of solar energy, realize natural circulation and improve indoor thermal comfort. At the same time, the system also makes comprehensive use of the technology of ground wind. The waste heat recovery technology and the natural circulation technology of coolant are used, and the system is simulated by using CFD technology and corresponding software, by establishing three-dimensional calculation model, dividing the grid and calculating the system. Using numerical simulation technology, the main influencing factors of intermittent self-heating of solar hot wind are simulated, including solar radiation intensity, heat collecting area, heat channel thickness, inlet and outlet size, characteristics of endothermic coating, etc. On the basis of optimizing the above parameters, the intermittent self-heating system of solar hot wind is simulated time by time, and the influence of outer cover plate on indoor temperature in winter and summer is analyzed. The optimal system opening and closing time for severe winter area is put forward. The application of ground wind technology in severe cold area is analyzed, and the influence of tunnel pipe length, pipe depth, pipe diameter, inlet wind velocity and pipe material on tunnel wind technology are studied by simulation technology. In this paper, the intermittent self-heating system of solar hot wind is analyzed in detail, and the operation analysis of intermittent solar heating system and ground-wind technology in winter and summer are studied respectively. It provides a good reference for the application of solar energy and ground wind technology in cold areas.
