Application And Study On The Village School Building Of Solar Heating In Cold Area

In recent years, building energy consumption in the countries the share of energy consumption is increasing with economic development. Reduce energy consumption, as an important measure to reduce energy consumption. As people's living standards in rural areas, the continuous improvement of rural life can be increased gradually with, especially in rural areas in northern cold heating coal increasing year by year, thus reducing heating in cold northern rural areas have become used to building energy efficiency an important issue. China's vast area of town cold winter school classrooms lack of heating measures, a small number of classrooms using coal-fired furnace heating, low levels of indoor thermal comfort, energy consumed in large quantities. With the improvement of economic level, school classrooms indoor comfort needs to be improved, using conventional energy will inevitably increase the energy burden; the most abundant solar energy resources in cold area, with the development of solar heating technology, excellent condition, use of solar heating technology can effectively improve village school in winter cold regions thermal comfort, it can effectively address social and economic development and energy supply shortage of contradiction.For the above, this cold region of the village school to study solar heating technology.First of all, through the adoption of field visits, field tests and questionnaire survey, on the cold region (Shandong) over the village and the school periphery structure of the mode of heating, towns and villages come to the school periphery structure of the insulation properties of the low, way behind the heating, indoor comfort Difference; selected cold regions of the typical school (store secondary) school buildings for heating heat load calculation for the solar heating solar heating technology research and design new basis.Then, on the use of solar hot water heating solar heating store middle school system is introduced, and in December 2009 on the heating effect and system performance testing and evaluation, test results show that:in the daytime outdoo℃r℃i efficiency of solar hot water system was 32.3%; find the store of solar hot water heating system is not successful secondary reasons:poor performance envelope insulation, auxiliary heat source economic conditions are not application and maintenance of water system piping to freeze damage inconvenience.Finally, high school shop solar heating project issues arising in solar air heating rehabilitation programs. On the feasibility of solar air heating were analyzed by the warm sun, solar vacuum tube wall temperature of the air collector to enhance biomass hot air heating stove auxiliary air heating system design; on the vacuum tube collector efficiency of the air collector built experimental platform for testing draw air collector, vacuum tube collector efficiency; on teaching high school shop outside the building envelope for energy saving design, simulation before and after reconstruction of building thermal load index change; of solar air heating system design, with ECTECT software to determine the installation of solar wall location and installation area, solar vacuum tube collector of the best air and best angle and the air towards the heating system to ensure the rate of solar energy; right to explore integrated design of solar heating, and solar air heating system to analyze the economic and social benefits.In this paper, a new type of solar air heating system can be widely used in cold areas such as village schools, office and residential buildings, which can effectively solve the heating problems in winter villages, improving indoor comfort in winter; but also can provide a useful reference for the design of solar heating.
