NEXT GENERATION AUTOMOTIVE SEAT COVER TO IMPROVE THERMAL COMFORT USING THERMOELECTRIC EFFECT
Keywords:
Ventilated Seat Cover, Peltier effect, Reduction in Human PerspirationAbstract
Thermal comfort is a condition of human mind that expresses physiological satisfaction with the thermal environment. To achieve this comfortable thermal environment almost all vehicles are equipped with heating, ventilation and air conditioning system. However the only heating, ventilation and air conditioning system is unable to circulate air all over the human body surface. The temperature of human body surface in contact with seat cover increases due to lack of air circulation between human body surface and seat surface. Next generation seat cover is developed to circulate the air between the gap of human body and seat cover. This seat cover blows air through the small holes of porous cushion material. This circulated air is cooled using thermoelectric effect. Circulating air absorbs moisture in the gap between the human body and seat surface. To validate the absorption of moisture experimentally, relative humidity of air between the gap before the fitment of seat cover and after the fitment of seat cover is measured. The experiment is carried out at three different time of the day, 9 am, 2 pm and 6 pm. 2-3% reduction in humidity is observed by using this next generation seat cover.
