Fig. 12From: Operational strategies to alleviate thermal impacts of the large-scale borehole heat exchanger array in Beijing Daxing AirportComparison of the temperature distribution between the non-strategic operation (a) and the strategic operation (b). The cold accumulation in Zone C is visibly alleviated with the lower \(\mathrm{z}\) and temperature value through the optimization, while the cooling in Zone A has little change with the similar \(\overline{{\Delta T }_{i,j}}\)Back to article page
