Abstract
In order to promote the vigorous development of renewable energy. Regarding the thermal load of buildings in Yulin mining area. Establish a solar deep buried pipe system using TRNSYS software. The feasibility of the components is verified by experiments. After comparing three different operating systems, it is concluded that the solar-medium and deep buried pipe system has more advantages. By simulating the solar energy - deep buried pipe system, it is concluded that: (1) The water supply temperature is relatively stable and can be maintained at 48 °C. (2) The COP can be up to 6.2, and the heat supply can also meet the building demand. (3) The cost is also low after long - term operation. Therefore, it is feasible to use solar energy-deep buried pipe system in mining area.
