| Abstract: |
| In this paper，using the method of exhaust ventilation , I builder a simulation test in the laboratory, and Proposed a new way to the wind, that is pulsating ventilation. This way can break the energy balance that caused by Continuing to the wind. Then increase the eddy disturbance. While leveraging the concentration diffusion of smoke make it Outward motion. It can Increase the ventilation distance and efficiency. Compared with the Continuing ventilation, Pulse to the wind also has advantages in energy saving. |
