Embodiment Construction

[0052] In the drawings and the following description which illustrate the invention in detail, the presence of fluid circulation is indicated by solid lines, while the absence of fluid circulation is indicated by dashed lines.

[0053] As shown in the figure, the air conditioning device of the present invention has an air conditioning circuit including a cooling fluid circuit 1 and a heat transfer fluid circuit 2 .

[0054] The cooling fluid circuit 1 is a closed circuit in which the cooling fluid circulates. The cooling fluid may be a subcritical cooling fluid, such as a fluorine-containing composition, in particular that known as R134A. The cooling fluid may also be a supercritical cooling fluid, such as carbon dioxide, known as R744A.

[0055] The cooling fluid is circulated under the action of a compressor 3 whose function is to increase the pressure and temperature of the cooling fluid. The compressor 3 is preferably electric, especially suitable for a working voltage o...

Abstract

The invention relates to a thermal conditioning device comprising a conditioning loop having a coolant circuit (1) and a heat-transfer fluid circuit (2), - the coolant circuit (1) comprising at least one compressor (3), one inner heat exchanger (11), one outer heat exchanger (28) and one evaporator (14), - the heat-transfer fluid circuit (2) comprising at least one first component heat exchanger (51) and / or one second component heat exchanger (52), one third component heat exchanger (67) and one radiator (69), - and a fluid / fluid heat exchanger (34) installed in the coolant circuit (1) and in the heat-transfer fluid circuit (2). The heat-transfer fluid circuit (2) comprises a first loop (47) and a second loop (48) interconnected by an interconnection device (49), the first loop (47) comprising the fluid / fluid heat exchanger (34) and the first component heat exchanger (51) and / or the second component heat exchanger (52), and the second loop (48) comprising the first component heat exchanger (51) and / or the third component heat exchanger (67) and the radiator (69).

Description

technical field [0001] The technical field of the invention relates to electric vehicles, in particular electrically driven vehicles. In particular, the invention relates to a thermal regulation device to ensure thermal regulation of the cabin or drive train of such vehicles. Background technique [0002] Currently, automobile manufacturers are developing new energy vehicles to complement or replace heat engine vehicles. In particular, there are vehicles whose propulsion is powered by electricity. Such a scheme is a meaningful choice. However, it is necessary to install different components connected to the electric drive train, such as batteries to store energy, electric motors to ensure the vehicle's propulsion, and inverters to provide electrical signals to the electric motors. [0003] The life and performance of these components (especially batteries) are affected by the ambient temperature. It is therefore necessary to keep these components at a predetermined tempe...
