In this work, a novel enhanced geothermal combined heat pump system (MLEGHP) is proposed for winter heating in severe cold regions. Taking Shenyang city as an example, we technologically investigate the applicability of this novel MLEGHP system in the heating-dominated regions over a 30-year period. Based on the real geological data, the hydraulic fracturing simulation and reservoir simulation are conducted successively. The results indicate that the MLEGHP system can continuously work efficiently without performance deterioration and strengthening the heating reliability during long-term operation in cold regions.
