摘要：With the development of society, more non-renewable resources such as coal have been consumed, leading to energy shortage and environmental pollution. In winter, a large amount of coal is burnt for heating in the north, causing heavier smog nationwide, which is a great threat to people's health. In recent years, some towns in the north also tried to provide heat for the buildings by burning natural gas to achieve boiler water circulation. However, that also caused environmental pollution to some extent. Research leads us to the invention of a solar heating system based on oil-water grading heat conduction and the design of pipelines and oil-water circulation in order to improve energy efficiency and improve heating quality in the north.
