摘 要 关键词：；；； Abstract Background of this graduation design topic is the current our country energy shortage and serious environmental pollution problems, the purpose of the paper is to design a economic, efficient and environmentally friendly solar and air source heat pump of hot water heating system. The current resources and the environment situation is not optimistic, sustainable development and environmental protection become the basic national policy of our country. In the resource consumption, building energy consumption accounts for a large proportion, the building energy saving measures is necessary. This article on the current situation, put forward by using the combined form of solar energy and heat pump for making hot water, and the article detailed the represented by direct expansion type and indirect type of solar energy heat pump system research situation in recent years. In this paper, we will combine with the practical situation of Qingdao region, and the characteristics of the building, through the methods of calculation, chart, complete system important component selection, connection, and adopt effective control system, and design a solar air source heat pump heating system. Finally, Based on the system compared with other heating methods of economic analysis, indicates that the system has reached the requirement of economy, high efficiency, energy saving.
