Abstract
The middle-deep geothermal system is receiving extensive attention due to its high efficiency and stable system operation. Selected the as the research object, the networked geothermal heating project in Weishi has been integrated and networked existing geothermal wells in the district since 2018. After the standardized network transformation, the networked geothermal heating system has complete heating for approximately 2,000,000 m2 and meet the heating needs of 60,000 people. In this paper, 10 networked retrofit projects have been selected for energy consumption analysis for three stable heating seasons, in which the system COP of each project can reach 4.8~5.8.It is confirmed that the networked mid-deep geothermal system has good sustainable development potential and promotion value in the future by comparing with other conventional clean energy heating projects.
