Performance Evaluation of Ground Heat Exchanger by Changing Water Volume
This paper summarizes existing evaluation methods of ground heat exchanger performance. Based on the characteristics of heat transfer in variable flow, comprehensively considering the similarity law of momentum transfer and heat transfer law, the performance of ground heat exchanger was evaluated in winter conditions by a comprehensive heat performance evaluation method – a combination of unit tube length for heat and pumps power consumption.
