Abstract

Features for a vapor compression system configured to cool and/or heat (i.e. thermally condition) two or more distinct climate controlled vehicle interior components via a common thermal bus are disclosed. Some embodiments employ a single compressor. Some embodiments employ multiple compressors and/or thermal buses, each servicing components located within respective interior thermal zones of a vehicle, for example a front row seat zone, second and/or third row seat zones, and/or an overhead zone and/or a trunk zone.

Claims

a fluid circuit configured to circulate a first working fluid in the fluid circuit;

a thermal energy source in thermal communication with the fluid circuit, the thermal energy source configured to heat or cool the first working fluid;

a first conduit in fluid communication with the fluid circuit, the first conduit configured to convey at least some of the first working fluid in the first conduit;

a first heat transfer device in thermal communication with the first conduit;

a first component within the thermal zone of the vehicle, the first component in thermal communication with the first heat transfer device, wherein the first heat transfer device heats or cools the first component via thermal energy transferred from or to the at least some of the first working fluid in the first conduit;

a second conduit in fluid communication with the fluid circuit, the second conduit configured to convey at least some of the first working fluid in the second conduit;

a second heat transfer device in thermal communication with the second conduit; and

a second component within the thermal zone of the vehicle, the second component in thermal communication with the second heat transfer device, wherein the second heat transfer device heats or cools the second component via thermal energy transferred from or to the at least some of the first working fluid in the third conduit.

2. The system of claim 1, further comprising a third conduit in thermal communication with the first heat transfer device and the first component, wherein the first heat transfer device transfers thermal energy between the first conduit and the third conduit.

3. The system of claim 2, wherein the third conduit is configured to convey a second working fluid in the third conduit that is different than the first working fluid, the second working fluid heated or cooled via thermal energy transferred from or to the first working fluid in the first conduit by the first heat transfer device.

4. The system of claim 3, wherein the first working fluid comprises a liquid and the second working fluid comprises air, and wherein the system further comprises a fan configured to move the air in the third conduit.

5. The system of claim 4, wherein the fan blows air toward the first component without recirculating the air to heat or cool the first component.

6. The system of claim 1, wherein the first component comprises a first one of a seat, a cup holder, and a bin of the vehicle.

7. The system of claim 4, wherein the third conduit is configured to recirculate the air in the third conduit, and wherein the fan moves the air in the second conduit to heat or cool the first component.

8. The system of claim 4, wherein the first component comprises an enclosure, and wherein the third conduit is configured to recirculate the air between the enclosure and the first heat transfer device.

9. The system of claim 4, wherein the first component comprises an enclosure, and wherein the third conduit is configured to recirculate the air within the enclosure.

10. The system of any of claims 1-9claim 1, wherein the second component comprises a second one of a seat, a cup holder, and a bin of the vehicle different than the first one of a seat, a cup holder, and a bin of the vehicle.

11. The system of claim 1, further comprising a thermal battery and a fourth conduit in fluid communication with the fluid circuit, the fourth conduit configured to convey the first working fluid in the fourth conduit, the fourth conduit in thermal communication with the thermal battery, wherein the thermal battery is configured to store thermal energy while the vehicle is operating and configured to release thermal energy when the vehicle is not operating.

12. The system of claim 1, wherein the thermal energy source comprises a vapor compression system.

17. A plurality of thermal conditioning systems according to claim 1, the plurality of thermal conditioning systems positioned within a passenger compartment of the vehicle.

18. The system of claim 1, further comprising an other thermal energy source in selective thermal communication with the fluid circuit, the other thermal energy source comprising a heat source configured to heat the first working fluid.

19. The system of claim 1, further comprising an other thermal energy source in selective thermal communication with the first conduit, the other thermal energy source comprising a heat source configured to heat the first working fluid in the first conduit to heat the first component.
