| 요약2 | Ground temperature recovery has a considerable impact on the performance of ground heat exchangers and ground-coupled heat pump systems. Some studies have found that consideration of ground temperature recovery in the design of ground heat exchangers allows for a reduction in the size thereof. Based on this finding, this study first investigates whether previous design methods and thermal analysis models for ground heat exchangers are appropriate for the design considering ground temperature recovery. We find that assumptions regarding heat extraction made in previous design methods make it difficult to consider ground temperature recovery. Simplified thermal analysis models for ground heat exchangers are also required to support the design. For these purposes, this study proposes an equivalent thermal analysis model for ground heat exchangers. This model is validated against measurement data of a sand-box test, and validation results demonstrate good agreement. We expect that the proposed model contributes to proposing design methods considering ground temperature recovery. |
