Experimental Investigation into the Cooling Water Distribution Parameters of a Unique Indirect Evaporative Cooler in Subway Station

Yecong He | Shan Liu


Abstract: Put forward a unique indirect evaporative cooler with rotary cooling water distribution device which is driven by a low-speed motor to solve the installation location problem of the cooling tower in subway station. This study investigates the air parameters of the Guangzhou subway stations exhaust channel in summer and winter, and optimizes the cooling water distribution method and the heat transfer performance of the indirect evaporative cooler. Results show that moving the cooling tower into the exhaust channel was feasible. Performance tests are conducted on an evaporative cooler consisting of heat exchanger coil that is cooled by a rotary cooling water distribution device, which flank spray cooling water on both sides of the coil. From the orthogonal experiment results, it is found that the air flow parallel to the normal direction of the heat exchanger, the thermal performance of heat exchanger is optimal, the water distribution devices best speed is 76 rpm, heat transfer performance increase with the mass flow rate of the cooling water and hot water, the cooling water inlet temperature and the air velocity. The increase of the water temperature and the air temperature declined the heat exchange performance, the cooling water inlet temperature change affect the heat exchange performance is the most significant, when the hot water temperature rise from 35 to 39, the heat transfer performance improved 37.62 %.
