Installation location of intact film plate evaporative cooler in underground railway stations

By applying plate heat exchanger and evaporative cooling technology, presents to substitute the intact film plate evaporative cooler for the cooling tower. Simulates the heat transfer performances of the device on conditions of concurrent flow, counter flow and cross flow. The results show a maximum local Nusselt number on cross flow condition, followed by concurrent flow, and a minimum on counter flow condition. By the comprehensive analysis of simulation results and installation and operation, recommends horizontal segment of extraction air duct in an underground railway station be the optimal location of installing the intact film plate evaporative cooler, providing reference for practical application.
