Application of a buried and concealed centrifugal blast cross-flow cooling tower to underground railway

According to the structural characteristics of the air duct and the entrance of underground railway stations, designs a novel centrifugal blast cross-flow side-out-wind cooling tower, in which the water falls vertically from the upper tower and air flow goes horizontally through the rain water discharge from the side of the packing. Tests the thermal performance of the tower by simulating the underground air duct environment, and finds that the required performance can be met at different air wet-bulb temperatures. Compares with conventional cooling tower and evaporative condensing chiller from the aspects of setting scheme, environmental impact, energy consumption and equipment investment. The results show that the cooling tower features compact, less investment, good landscape, low noise, more energy saving and environmental protection.
