How Seat Cooling technology works

Unless you live inside the Arctic Circle, you probably think an air conditioner is a necessary accessory for your car, especially on those days of summer when you find yourself trapped in slow-rolling traffic and even the windows down doesn’t realise you from the heat.

For this issue Seat ventilation is a feature that is offered in many luxury cars today as well as Non-luxury such as Toyota Avalon, Nissan Pathfinder, and Honda Odyssey all offer this feature.

The system works by using a clever combination of perforated leather and small fans integrated into the seats. Some systems also incorporate a micro cooling element, much like an air conditioner.

While the number of fans and the exact system design varies depending on the auto manufacturer, all of them work on the same principle. They draw in air from the cooler, lower area of the passenger compartment and transfer it uniformly to the seat cushion and back rest.

These fans create air flow, at adjustable intensities, through the fine perforations in the leather. This quickly cools the surfaces of the seats to a pleasant temperature, even if the vehicle has been heated by an intense amount of sunlight for a long period of time. The finely perforated leather upholstery absorbs perspiration to create a pleasant feeling.

On one hand, a standard car seat blocks your body's built-in cooling system. Ordinarily you eject heat through your pores in the form of water vapors, which carries the heat invisibly into the air. However, seat stop this process as they absorb the body sweat especially in leather seats.

On the other hand, cooling system the gently circulating air of a ventilated seat carries away your body heat and helps to keep you cooler and your clothes drier during warmer months.

On some vehicles, the heated and ventilated functions can even be used simultaneously, circulating the seat heating more quickly. This is an added benefit on cold or damp days as the dual function helps to dry off clothes or keep you warm and dry as quickly as possible.

How does this help to reduce fuel consumption?

The ventilated seats keep vehicle occupants cooler, they consequently reduce the use of the vehicle’s air conditioning system to achieve the desired level of comfort.

So by confining the cooled air directly to the spot where the hot driver (or passenger) is sitting, air-conditioned seats use energy more efficiently than the air conditioners that cool the entire interior of the car. They don't completely eliminate fuel use and pollution, but they minimize it.

So while it’s not quite as nice as jumping into a swimming pool on a hot day, this latest technology not only helps to keep you cool but your cash in your wallet too. So Look for it on the next vehicle!
