Abstract

A device for thermal conditioning includes a cooling fluid circuit, a heat transfer fluid circuit, and a fluid/fluid heat exchanger that is intended to enable thermal exchange between the cooling fluid and the heat transfer fluid. The cooling fluid circuit includes at least one compressor, a first outer heat exchanger through which an outer air flow passes and a first evaporator. The heat transfer fluid circuit includes at least a first inner heat exchanger, a first heat source and a second outer heat exchanger through which the outer air flow passes. The cooling fluid circuit includes a second evaporator.

First claim

The invention claimed is:

1. A thermal conditioning device including a cooling fluid circuit, a heat transfer fluid circuit, and a fluid/fluid heat exchanger,
wherein the cooling fluid circuit includes at least one compressor, a first outer heat exchanger through which an outer air flow passes, and a first evaporator,
wherein the heat transfer fluid circuit includes at least one inner heat exchanger, a first heat source and a second outer heat exchanger through which the outer air flow passes,
wherein the cooling fluid circuit further includes a second evaporator,
wherein the first evaporator is constructed for the passage of the outer air flow, and
wherein the outer air flow successively passes through the second outer heat exchanger, then through the first evaporator.

2. The thermal conditioning device as claimed in claim 1 , wherein the second evaporator is installed in the cooling fluid circuit, in parallel with the first evaporator.

3. The thermal conditioning device as claimed in claim 1 , wherein the cooling fluid circuit includes a management unit for circulating the cooling fluid towards the first evaporator and/or the second evaporator.

4. The thermal conditioning device as claimed in claim 3 , wherein the cooling fluid circuit includes a single management unit for circulating the cooling fluid towards the first evaporator and/or the second evaporator.

5. The thermal conditioning device as claimed in claim 1 , wherein the first outer heat exchanger is constructed for the passage of the outer air flow prior to the passage of the outer air flow through the first evaporator.

6. The thermal conditioning device as claimed in claim 1 , wherein the first outer heat exchanger is constructed for the passage of the outer air flow prior to the passage of the outer air flow through the second outer heat exchanger.

7. The thermal conditioning device as claimed in claim 1 , wherein the heat transfer fluid circuit includes at least a first loop including the fluid/fluid heat exchanger and the inner heat exchanger.

8. The thermal conditioning device as claimed in claim 1 , wherein the heat transfer fluid circuit includes a second loop including the fluid/fluid heat exchanger, the first heat source and a second heat source.

9. The thermal conditioning device as claimed in claim 8 , wherein the second loop includes a third outer heat exchanger installed in series with the second heat source and constructed for the passage of the outer air flow prior to the passage of the outer air flow through the first evaporator.

10. The thermal conditioning device as claimed in claim 9 , wherein the third outer heat exchanger is constructed for the passage of the outer air flow prior to the passage of the outer air flow through the second outer heat exchanger.

11. The thermal conditioning device as claimed in claim 8 , wherein the third outer heat exchanger and the first outer heat exchanger are constructed for the passage of distinct portions of outer air flow.

12. The thermal conditioning device as claimed in claim 1 , wherein an inner air flow intended to be distributed in the passenger compartment of a vehicle passes through the inner heat exchanger and the second evaporator.

13. A thermal conditioning device including a cooling fluid circuit, a heat transfer fluid circuit, and a fluid/fluid heat exchanger,
wherein the cooling fluid circuit includes at least one compressor, a first outer heat exchanger through which an outer air flow passes, and a first evaporator,
wherein the heat transfer fluid circuit includes at least one inner heat exchanger, a first heat source and a second outer heat exchanger through which the outer air flow passes,
wherein the cooling fluid circuit further includes a second evaporator, and
wherein the first outer heat exchanger is constructed for the passage of the outer air flow prior to the passage of the outer air flow through the first evaporator.

14. A thermal conditioning device including a cooling fluid circuit, a heat transfer fluid circuit, and a fluid/fluid heat exchanger,
wherein the cooling fluid circuit includes at least one compressor, a first outer heat exchanger through which an outer air flow passes, and a first evaporator,
wherein the heat transfer fluid circuit includes at least one inner heat exchanger, a first heat source and a second outer heat exchanger through which the outer air flow passes,
wherein the cooling fluid circuit further includes a second evaporator, and
wherein the first outer heat exchanger is constructed for the passage of the outer air flow prior to the passage of the outer air flow through the second outer heat exchanger.
