The inventive method includes the utilization of different phase change material (3,5,7) with different melting temperature ranges in each of the headliner, the seats, and the instrument panel of an automobile in order to save energy while improving thermal comfort for passengers. When used in seats, the phase change material (3,5,7) can be included in a seat heater system. Preferable phase change materials (3,5,7) are alkyl hydrocarbons and mixtures thereof, salt-hydrates, metals, alloys, poly-alcohols, and eutectics with phase changes occurring within the desired temperature ranges and with appropriate heat storage capacities. Preferably, the phase change materials (3,5,7) are directly incorporated in a polymeric compound structure, in an elastomeric compound structure, or in a foam structure (2) with microencapsulation in order to enhance the overall thermal capacity. When used in the seats, the phase change material incorporated in a polymeric structure is formed into a mesh-like material and attached to a knitted spacer fabric (6). |
