Fig. 10From: Operational strategies to alleviate thermal impacts of the large-scale borehole heat exchanger array in Beijing Daxing AirportComparison of z difference (\(\Delta z\)) between Scenario #0 and Scenarios #1–#4. The negative value indicates the cold accumulation is minimized, and vice versa, The strategies simulated by Scenario #1, #3 and #4 could alleviate the cold accumulation with negative valuesBack to article page
