The Numerical Simulation and Research and Application of Energy-Saving Effect of Air Curtain of the Dining Room

Abstract

The dining room door with going out and coming in of people and goods is often opened, heating and air-conditioning building in order to energy-saving and preventing the outdoor air on indoor environment influence, install a set of air curtain at the entrance of the dining room door to stopping the outdoor air, commonly used air curtain is ceiling type air curtain. This article in view of the gate of one area, a layer of the dining room of Hebei University of science and technology of a new campus area set up physical model of air curtain and reasonable simplification, determining the calculation area of the numerical simulation and air curtain close condition. Then adopting the UFD method to wind pressure, hot pressure and the air curtain air flowing of the local hot pressure stack of main entrance set up physical model, through the numerical simulation of air curtain different jet angle, demonstrate the air energy-saving effect, provide the reference for the choice of the air curtain.
