ABSTRACT
The tube indirect evaporative cooler is energy-saving and environmentally friendly, and its heat transfer mechanism still needs to be fully indicated, for which the numerical method is more suitable than the experiment. Because many numerical researches focusing on the tube indirect evaporative cooler are usually based on the simplified models, such as single tube model, single side model, 1-D, and 2-D model, the further improvement is still needed. Meanwhile, the tube indirect evaporative cooler is always expected to supply more cooling air with lower temperature at lower cost of energy, but many present studies are focusing on the improvement of heat transfer only and ignoring the energy cost. This paper proposed a 3-D full-scale numerical model and method verified by the experimental data, by which, the energy output (primary air-cooling capacity) and quality (temperature of primary air outlet) at the resistance loss (resistance) of the tube indirect evaporative cooler are analyzed with the help of FLUENT software.
