The optimized matching of passive solar energy supply and classroom thermal demand of rural primary and secondary school in northwest China

摘要

The heating problems of rural primary and secondary school must be solved urgently in Northwest China. However, central heating systems are difficult to implement in rural areas due to the level of economic development. It is known that the solar energy resources are much richer in Northwest China. So, it is possible to improve the indoor thermal environment using passive solar technology. In this study, the temperatures of three types of passive solar houses were calculated using dynamic simulation. The accuracy of the model was verified by experiments. Combined with the particular demands of rural school, the indoor environment is analyzed at different modes in different areas to determine the optimal type of passive solar house. These areas were divided into four zones: most suitable areas, more suitable areas, less suitable areas and unsuitable areas. The priority degree for different types ofpassive solar houses under different modes was determined.
