In recent years, in order to improve the living standard of urban residents and control the influence of haze weather, many cities in the north have gradually introduced a number of measures. Beijing took the lead in setting an example by implementing the national clean energy transformation benchmark of "replacing coal with electricity", Shijiazhuang, Hebei, introduced subsidies for residents to adopt new heating heat pumps, and Tianjin, Tianjin, introduced a policy to eliminate small coal-fired boilers, Instead, it advocates the use of new low-carbon and energy-saving heating equipment, such as air energy heat pump heating. Recently, Henan has introduced the implementation plan of replacing coal-fired boilers with air energy heat pump heating, which provides a policy basis for comprehensively promoting the replacement of coal-fired boilers with air energy heat pump heating.

Henan, Tianjin and other places have increased the urban environmental quality, but also brought new development opportunities for the domestic air energy heat pump industry. It is reported that the air energy heat pump is one of the most advanced heating equipment with the highest energy efficiency ratio in the world. Its primary characteristics are environmental protection and energy conservation. It is not only zero emission and environmentally friendly, but also absorbs 2-6kW free heat from low temperature heat source for every 1kW of electric energy consumed by the heat pump under different working conditions. The energy-saving effect is very significant. It plays an important and important role in improving the current haze weather and global air pollution.

Air energy heating is not only efficient, energy-saving, low-carbon and environmentally friendly, but also can meet the needs of sustainable development and environmental protection of the country's heating. It is consistent with the development idea of energy conservation and emission reduction, and is the best choice to replace coal-fired boiler heating. At present, the domestic air energy application technology has been developed quite maturely. Like GEME, the air energy heat pump heating application technology has reached the international advanced level. The floor heating unit system products produced by GEME have been widely used in the heating market in the north, with remarkable use effect. In addition, it has won the affirmation and praise of consumers and relevant departments in most areas of the north, providing a good solution for the clean heating in winter in the north.
