Patent ID: 8393162

Claim:
A temperature control system supplies temperature-controlled air to a vehicle seat so as to control temperature of the vehicle seat, comprising: an air duct; an air-blowing device urging air to flow through the air duct; a seat back temperature control unit performing heat exchange between air flowing in the air duct and air supplied to a seat back so as to control temperature of the air supplied to the seat back; and a seat cushion temperature control unit performing heat exchange between air flowing in the air duct and air supplied to a seat cushion so as to control temperature of the air supplied to the seat cushion, wherein the air duct forms a single air passage passing by the seat back temperature control unit and the seat cushion temperature control unit so that the air flowing in the air duct undergoes heat exchange with one of the seat back temperature control unit and the seat cushion temperature control unit and then undergoes heat exchange with the other.
