However, the rapid rise in recent years, computer simulation, so many engineers calculate the relationship between thermal comfort within the cabin air conditioning system and bus passengers using numerical simulation methods, and then discuss the passenger optimal thermal comfort. Doing research paper on the thermal comfort of the air temperature inside the cabin, computer numerical analysis of thermal comfort inside the cabin passengers to do the analysis, and forecasting so that passengers can feel the most comfortable temperatures to look forward to in a quantitative simulation data so that passengers know why the comfort of the cockpit. After computer numerical analysis results are as follows: increased air outlet speed can improve the strength of convection within the cockpit to help in the rapid cooling of the cabin temperature environment. Coach of the air outlet is provided generally at the top of both sides of the car, the central aisle of the cabin cool is not easy to form a conditioned corner. The new design at the top surface of a comprehensive set cabin air vents, air conditioning can not only expand the effective range, and can effectively cool the cabin central aisle range, and can be reduced by about one-third of the air consumption. That is effectively setting the cockpit and the air outlet vents enhance air flow rate can be more quickly reduce the temperature inside the cockpit of the time, the effect of the cold room is relatively good, but also more power.
