Method for ventilating a seat

A method for cooling a seat of a transportation vehicle, comprising:

• placing a seat insert over a seat cushion and below a seating surface of a transportation vehicle seat;
• drawing ambient air to a location beneath the seating surface and into the insert and into a mixing region of the seat;
• mixing the drawn ambient air with a cooled fluid provided to the mixing region;
• removing the resulting mixture from the mixing region;
• and
• providing the cooled fluid through the use of a thermoelectric device, the thermoelectric device including an active side and waste side and adapted to provide heating and cooling by passing electricity through the device, wherein the cooled fluid is provided by the active side of the thermoelectric device.

A method for cooling a seat of a transportation vehicle, comprising:

• placing a seat insert over a seat cushion and below a seating surface of a transportation vehicle seat;
• drawing ambient air to a location beneath the seating surface and into the insert and into a mixing region of the seat with a fan;
• mixing the drawn ambient air with a cooled fluid provided to the mixing region;
• removing the resulting mixture from the mixing region by locating the fan down stream from the mixing region;
• providing the cooled fluid through the use of a thermoelectric device;
• and
• maintaining the pressure in the mixing region below the ambient pressure so that substantially all of the resulting mixture does not pass through the seating surface.
