Improved air distribution through new AC vent design for 3x2 seating layout in air Conditioning buses

With the improvement of standard of living, air-conditioning has widely been applied in buses. However, in air conditioning buses air distribution is still needs to be improved, One of the main reasons for this sub-quality comfort is two air flow louvers arrangement for 3x2 layout air conditioner buses. Air conditioning buses hatrack louvers are on integral part in providing comfort to passengers. General trend of the numbers of louvers provided to passengers is two louvers for three seats. Disadvantage of having conventional two louvers is that, there is always one passenger left with no option of directing air towards that person. This lead to an opportunity to design three louvers type hatrack instated of conventional two louvers hatrack, for 3x2 seating layout of buses. This way all three passengers can control the louvers for their own comfort and mass of air flow is sufficient for third passenger as well. This new design air distribution had been tested through CFD and air flow through all louvers is meeting minimum average 4.5m\s air velocity through hatrack. Physical trails and testing in customer vehicles are planned. This new hatrack can cater air flow requirement of all seating layouts i.e. 3x2, 2x2 & 2x1.
