Ventilation system of Railway, modified to versatile one - Turbo ventilation

Abstract

The act of supplying fresh air and getting rid of foul air is ventilation. A mechanical system that provides fresh air is ventilation system. It is very useful in controlling indoor air quality. Many Indians travel by railway daily. Most of the Indian Railways are provided with natural ventilation by windows and doors. If all windows and doors are closed or the crowd is more, this type of ventilation system fail to provide effective ventilation. This creates suffocation. Also, smoke, dust, foul smell, etc. once trapped, it becomes very difficult to throw it out. Thus, there is a need of alternate ventilation. Turbo Ventilation is a solution for this. Turbo Ventilation includes a passage for natural wind to pass through a unit which in turn produces electricity and then air is further sent to passengers in railway coach. This system not only provides proper ventilation, but also works as exhaust system whenever required. This has many advantages over the present ventilation system with some limitations and that too at reasonable cost. Considering average speed of railway as 60Km/h wind flow will also be the same. Thus, we get 22.42 Km/h speed of air after passing it through turbine. For one hour journey, we get 60kmph for average 45 minutes. Thus, the power produced by one unit for one hour journey = 218.7W.
