Solar energy is unlimited clean energy, on energy and environmental issuescurrently facing the dual pressures of human society has great allure. However, basedon the low energy density of the solar radiation characteristic scale use of solar energyis always difficult to solve. In this paper, a small-scale single building as an object,carried out with a single heat source for the building of solar heating technology andapplied research.Based on the review of previous research on the methods and discusses the use ofsolar energy to alleviate the current energy and environmental issues is important.Solar thermal utilization target, describes the main calculation. In ShanhaiguanDistrict, Qinhuangdao building small villa for the object, Specific conducted solarthermal design calculations.Determine the thermal storage tank solar heating systems,solar collectors specific sizes.Design and calculation results show that, using solar energy as a single source,according to the traditional heating mode, heating mode, need a large water tank,occupy a larger space, especially the thermal collector area of great, will lead to theincrease of the initial investment. These are the main technical barriers in single heatsource heating by solar energy. In order to solve these problems, in this paper thesingle solar heating and room adjustment with the heating scheme, thus the collectorarea and volume of heat storage water tank is reduced by more than2/3, to be acceptedto current conditions of the state.According to the theoretical calculation results approximate design, constructionand operation results show that solar heating system, heating effect in accordance withthe relevant national technical specifications, and due to the adoption of lowtemperature radiant floor heating system, room adjustment problem is easy to solve.Hence, solar energy heating system must be combined with room adjustment operationscheme, in order to meet the demand of building heating.Research papers also showed that low-density and fluctuations of solar energy is an objective reality, can not be changed to improve the collection efficiency of solarcollectors is also very limited.So, try to use a single solar heat source heating isunrealistic in large buildings, but must be combined with other sources of heat.Sincethe solar thermal collector area is limited installation space and the initial investment,the larger the building, the lower the percentage of available solar heating.However,China’s vast rural areas and small towns, as part of residential and public buildings issmall, with a single heat source for the building of solar heating technology has broadapplication prospects, can make an important contribution to China’s energy-savingand emission reduction.
