Abstract
With the establishment of 3060 double carbon target, higher requirements are put forward for clean energy heating of new buildings in China. Among them, air source heat pump has entered the public’s field of vision with its characteristics of cleanness, environmental protection and high operating efficiency. With the development of heat pump technology, air-source heat pump can run stably at -25°C, and Zhangjiakou, which is located in a cold area, can also use air-source heat pump as the heat source of office buildings. At the same time, the economic analysis shows that the building heating cost of air source heat pump heating system is more economical and energy-saving than that of new central heating system.
