Abstract
Disclosed is a method and a device for thermally controlling a plurality of cabins of a vehicle from a mixing chamber supplied with air from at least one air supply device of which at least the temperature is controlled, each cabin being supplied with air by a supply conduit specific to this cabin. At least one cabin is supplied with air at a temperature adjusted by at least one individual exchanger associated with the supply conduit specific to this cabin, in which a second circuit is supplied with a heat transfer fluid from at least one heat transfer fluid thermal regulation loop of the vehicle. Also disclosed is a vehicle provided with at least one thermal control device.
Claims19
Method for thermally controlling a temperature of the air within a plurality of cabins of a vehicle, the vehicle having a mixing chamber supplied with air from at least one air supply device, said method comprising the steps of:
- supplying each cabin with air:
- from the mixing chamber,
- by a supply conduit specific to said cabin,
- independently of the other cabins,
- wherein:
- supplying at least one cabin of plurality of cabins (13 to 18) with air at a temperature adjusted by at least one heat exchanger, named individual exchanger, associated with said supply conduit specific to said cabin,
- passing air from the mixing chamber through a first circuit of each individual exchanger associated with said supply conduit specific to said cabin and independently supplying said cabin, this first circuit being interposed between said cabin and the mixing chamber on said supply conduit specific to said cabin,
- supplying at least one second circuit of at least one individual exchanger associated with a supply conduit specific to said cabin with a heat transfer fluid from at least one thermal regulation loop of the vehicle,
- said heat transfer fluid being selected:
- from:
- at least one said heat transfer fluid bled from said thermal regulation loop of the vehicle at a temperature greater than the temperature of the air from the mixing chamber, and
- at least one said heat transfer fluid bled from said thermal regulation loop of the vehicle at a temperature lower than the temperature of the air from the mixing chamber,
- such that each individual exchanger associated with the supply conduit specific to said cabin individually adjusts the temperature of the air supplying said cabin based on a set temperature for said cabin,
- wherein said heat transfer fluid is selected from:
- at least one said heat transfer fluid that is bled from said thermal regulation loop of the vehicle at a temperature greater than the temperature of the air from the mixing chamber when said set temperature is greater than the temperature of the air from the mixing chamber, and
- at least one said heat transfer fluid that is bled from said thermal regulation loop of the vehicle at a temperature lower than the temperature of the air from the mixing chamber when said set temperature is lower than the temperature of the air from the mixing chamber.

Device for thermally controlling a plurality of cabins of a vehicle, comprising:
- a mixing chamber,
- at least one air supply device connected to the mixing chamber for supplying said mixing chamber with air at a controlled temperature,
- an automatic thermal management arrangement suitable for controlling at least the temperature of the air delivered by each air supply device to the mixing chamber based on at least one set temperature of at least one cabin of plurality of cabins of the vehicle,
- each cabin being connected to the mixing chamber by a supply conduit specific to said cabin so as to be able to be supplied with air from the mixing chamber independently of the other cabins,
- wherein:
- at least one heat exchanger, named individual exchanger, is associated with at least one said supply conduit specific to said cabin,
- each individual exchanger comprises:
- a first circuit interposed between said cabin and the mixing chamber on said supply conduit specific to said cabin to be able to have air from the mixing chamber pass therethrough and to supply said cabin,
- a second circuit connected to at least one heat transfer fluid thermal regulation loop of the vehicle to be able to be supplied with said heat transfer fluid,
- said automatic thermal management arrangement is suitable for supplying at least one said second circuit of at least one individual exchanger associated with a supply conduit specific to said cabin with said heat transfer fluid from at least one said thermal regulation loop of the vehicle,
- said automatic thermal management arrangement is suitable for selecting said heat transfer fluid:
- from:
- at least one said heat transfer fluid bled from said thermal regulation loop of the vehicle at a temperature greater than the temperature of the air from the mixing chamber when said set temperature is greater than the temperature of the air from the mixing chamber,
- at least one said heat transfer fluid bled from said thermal regulation loop of the vehicle at a temperature lower than the temperature of the air from the mixing chamber when said set temperature is lower than the temperature of the air from the mixing chamber,
- wherein said heat transfer fluid is selected such that each individual exchanger associated with the supply conduit specific to said cabin individually adjusts the temperature of the air supplying said cabin based on a set temperature for said cabin.
