Uncovering the Efficiency and Performance of Ground-Source Heat Pumps in Cold Regions: A Case Study of a Public Building in Northern China

In cold regions, due o the impact of climatic conditions, heat load in winter and cooling summer are unbalanced. long-term operation ground-source pump (GSHP), soil imbalance phenomenon has still not been successfully solved. Therefore, this study took GSHP a public building area northern China as research object. Based on unit performance data system over 8 years measured temperature field, efficiency region variation law field were explored. order to further problem imbalance, effect exchange hole groups at different intervals underground thermal environment after 30 was simulated, optimization scheme spacing proposed. The results support improvement design construction, have important practical significance for popularization GSHPs regions.
