Abstract: Heat exchanger, for example for a motor vehicle air-conditioning circuit, comprising a plurality of tubes (12) for circulating a heat-transfer fluid, the ends of said tubes (12) opening into manifolds and reservoirs (11) of thermal storage material in contact with the tubes (12) so that the storage material and the heat-transfer fluid exchange heat with one another. The exchanger comprises a plurality of heat-exchange elements (4) each housing at least one reservoir (11) and at least one tube (12) which are nested.

Abstract: The invention is related to an AC loop (12) for ventilation, heating and/or air conditioning installation comprising, according to the circulation of an refrigerant in the AC loop, at least a compressor (14), a first heat exchanger (16) for heating an air flow distributed into the passenger compartment, a first expansion device (18), an exterior heat exchanger (20) and a second heat exchanger (24). The AC loop (12) comprises a storage device (28) connected to the outlet of the first heat exchanger (16) and to the outlet of the exterior heat exchanger (20).

Abstract: The invention relates to a heat exchanger, in particular for an air conditioning, ventilation and/or heating device of a motor vehicle, said heat exchanger comprising a plurality of stacked modules (100) which define two series of distinct channels for circulation of first and second heat transfer fluids and are connected to inlet and outlet ducts (101, 102, 104, 105) for both heat transfer fluids.

Abstract: The invention relates to an air conditioning device for the passenger compartment of a vehicle, said device comprising a first closed loop (BF) which contains an evaporator (BF5), through which an air stream (F) may flow, and in which a first coolant may flow such as to transfer cold to said air stream in the evaporator. According to said invention, the device comprises a second closed loop (BS) in which a second coolant may flow between the evaporator (BF5) and a tank (BS2), such as to receive cold from the first coolant in the evaporator for storing the same in the tank and returning to the air stream in the evaporator, according to the cooling capacity, produced by the first loop and to the air conditioning needs.
