Under the background of achieving"emission peak and carbon neutrality"in China,in response to the demand of people in the south for winter heating,it is urgent to explore a residential heating mode suitable for the climate characteristics of the south while taking into account economic and environmental protection.Taking a new residential district in south China as an example,this paper analyzes and compares the different heat source forms of the central heating system in the residential district.The heat source scheme comparison and selection idea are introduced,as well as the system setting and operation principle of the combined heating of ground source heat pump and air cooled heat pump in detail,focusing on the comparative analysis of the economy of the two heat sources with different matching ratios;The design points of the energy room and ground source side of the system are summarized;The methods to improve the heat imbalance of the soil on the ground source side of the ground source heat pump system in winter and summer is expounded;The judgment conditions for auxiliary cooling operation of the ceiling radiation system in summer are provided;The setting mode and construction method of ceiling radiant heating terminal in residential buildings are analyzed.
