Paper No 110 – Case Study of the Largest Air Source Heat Pumps Central Heating Project in China – 14th IEA Heat Pump Conference, Chicago, USA
This paper summarizes the best practices for Air Source Heat Pump (ASHP) central heating systems in large-scale residential buildings. Central heating of residential buildings in northern China typically depends on coal-burning power plants, which are the main sources of reducing such pollution as well as carbon emissions. The project described in this paper is one biggest ongoing ASHP heating projects in the world. More than 1,200 units of ASHPs were deployed as heating sources in northern China, heating approximately 4 million square meters of living spaces in large residential buildings. Various parameters were monitored and collected over about 120 days during the heating season from 2019 to 2020. Operating costs and carbon dioxide emissions were measured and compared to the corresponding figures for equivalent heating by other systems. It is demonstrated that ASHP systems are well suited for meeting the heating requirements of this region while reducing operating costs and greenhouse gas emissions.
