| With the rapid growth of energy consumption, China has become the world’s most important energy consuming country and the most serious environmental pollution area. The rapid growth of China’s energy demands and coal based energy consumption structure makes environmental pollution increasingly intensified, resulting in atmospheric pollutants such as smoke and dust, sulfur dioxide, nitrogen oxides, carbon dioxide emissions are among the first in the world. Therefore, the use of new energy sources is becoming more and more important.In this paper, the application of solar energy air source heat pump system in Shijiazhuang, which includes a small rural cottage and a city Villa, is studied in this paper. Two types of solar water heating system, air source heat pump water system and solar air source heat pump system are simulated, and the performance of the solar energy hot water system, air source heat pump system and solar air source heat pump system is analyzed. The system can be used to promote the two types of independent buildings. The performance analysis shows that the solar energy air source heat pump system has an average of 0.45 in the whole heating season, and the solar energy efficiency is 46%, the average COP of the air source heat pump system is 4.5, compared with the air source heat pump system. In the entire heating season, the contribution rate of the solar collector is 59%, and the contribution rate of air source heat pump is 41%. Economic analysis shows that: solar water heating system is more economical in the independent building of the small cottage style in the countryside; and the solar energy air source heat pump water heater system is more extended in the City villa. |
