Abstract

The technical and economic aspects of a district heating system coupled with a deep open-loop geothermal well (DOLGW) and heat pumps were studied in the paper. A typical configuration of such a geothermal district heating system was proposed, and the corresponding thermal analysis was carried out. Based on the data from the DOLGW heat extraction test conducted in Hebei, China, the optimal size selections of heat pumps, plate heat exchangers, and terminal heat radiators for such a system was analyzed theoretically. In addition, an optimal control scheme for such a system with the change of environmental temperature or heating load were given.
