1. An air-conditioning device for a motor vehicle comprising:
an air-conditioning loop which includes:
a first heat exchanger that is in contact with outside air, and
a second heat exchanger that is placed in an air conditioning housing, and
at least one element for cooling the outside air which includes a composite phase-change material made of at least one first material which is a phase-change material and at least one second material of which the structure forms a support matrix within said phase-change material, wherein said composite phase-change material is covered with a heat-conducting protective layer, and wherein said at least one element for cooling surrounds at least in part said second heat exchanger.
 
18. An air-conditioning device for a motor vehicle comprising:
an air-conditioning loop which includes:
a first heat exchanger that is in contact with outside air, and
a second heat exchanger that is placed in an air conditioning housing; and
at least one element for cooling the outside air which includes a composite phase-change material made of at least one first material which is a phase-change material and at least one second material of which the structure forms a support matrix within said phase-change material, wherein said composite phase-change material is covered with a heat-conducting protective layer, and wherein said at least one element for cooling forms a diffusion grating at an outlet of an air diffuser in a passenger compartment of the motor vehicle.
 
19. An air-conditioning device for a motor vehicle comprising:
an air-conditioning loop which includes:
a first heat exchanger that is in contact with outside air, and
a second heat exchanger that is placed in an air conditioning housing: and
at least one element for cooling the outside air which includes a composite phase-change material made of at least one first material which is a phase-change material and at least one second material of which the structure forms a support matrix within said phase-change material, wherein said composite phase-change material is covered with a heat-conducting protective layer, and wherein said at least one element for cooling surrounds at least in part said second heat exchanger and forms flaps for orienting and/or closing off air flow entering a passenger compartment of the motor vehicle.
