Seat Ventilation System Design and Customization Using the Peltier Module

Comfort and elegance are one of the most important characteristics people are looking for during their travels. Nowadays the satisfaction of the modern cars had been developed to the greater extent. In order to increase the sophistication to the passengers during travelling we came up with an idea to provide ventilation to them by blowing cold air at their rear side. The objective of this project is to provide seat ventilation using thermoelectric module. The thermoelectric module is powered using the DC current from the battery and the module works on the principle of Peltier effect. The module on providing supply, a junction becomes cold and the low temperature developed at one end is used to provide seat ventilation [39]. A centrifugal blower is used to blow air over the module's cold junction which causes the air-cooling effect. Now the air is blown through the distribution pads that are mounted over the seats in seat upholstery and the ventilation of the seat is successfully received. On the other hand, the hot junction temperature is dissipated using the heat sink attached to it. A fan is used to draw out the heat from the heat sink through convection. The seat models in the upholstery which are provided with perforated holes are first modelled using CATIA and then tested for safer design and stability. This system is more economical and provides more efficiency during operation in order to increase the satisfaction to the people at low rate of cost.
