- Abstract
- The objective of this study is to improve the performance of a hybrid ground source heat pump (HGSHP) by optimizing the flow distribution ratio of secondary fluid flow rate between a ground loop and a supplemental loop. Initially, a conventional ground source heat pump (GSHP) was tested to determine an optimum flow rate of the secondary fluid. Based on the selected optimum value, the HGSHP was also tested by varying the flow distribution ratio of the secondary fluid flow rate between the ground loop and the supplemental loop, such as 9：1, 7：3, 5：5, and 3：7. The results showed that the optimum flow distribution ratio of the secondary fluid flow rate was 7：3. The COP of the HGSHP was improved by 19% over the GSHP at a flow distribution ratio of 7：3 and an entering water temperature of 40℃.
