Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Conference Paper Description
The ground temperature increase is the crucial problem that influences the longterm performance of Ground Source Heat Pump (GSHP) system in cooling dominated region of China. In this report, the numerical simulation model based on the heat rejection model of an insitu Thermal Response Test (TRT) is created using TRNSYS simulation tool. Seven different thermal conductivity backfills are simulated for 1, 5, 10, 15 and 20 years. The result illustrates that the higher conductivity backfills improves the heat exchange performance between BHE and surrounding ground but it also increases the ground temperature in cooling dominated regions for long terms operation. In the case of Chuzhou city of this study, when the conductivity of backfill is higher than 1.9 W/(m·K) which is closest to the thermal conductivity of the surround ground, there are little growth in ground temperature as well as the heat exchange performance.
