Numerical Study of Effect of HVLS Fan on the Temperature Distribution in the Logistical Warehouse with Rack

초록

The numerical study of effect of high-volume-low-speed(HVLS) fan on the temperature distribution in the logistical warehouse with rack is performed. The size of logistical warehouse is 33mⅹ66mⅹ10m and the size of rack is 21mⅹ6mⅹ9m. The total 7 racks are installed in the center of logistical warehouse. The two unit coolers are employed to cool down the air and three HVLS fans are installed at the upper side in the logistical warehouse. The temperature and the velocity of cool air from unit cooler is -1℃ and 5m/sec, respectively. The numbers of used computational sell are 1.4millions. MPI method is used for parallel computation. Large Eddy Simulation method (LES) is adopted to solve the momentum and energy equations. Buoyancy force term is included in momentum equation. The unsteady flow characteristics is investigated. The HVLS fan is recommended for increase of cooling efficiency in the logistical warehouse.
