Problems solved by technology

Now, the use of these valves makes the wiring of the circuit particularly complicated, which constitutes the first disadvantage of the known circuit
[0006] The second disadvantage lies in the use of accumulators
Specifically, this part is particularly bulky, making its installation on the vehicle more complicated and detrimental to the cost of the refrigerant circuit
Furthermore, the use of an accumulator does not allow for a performance trade-off between the above four modes of operation

Abstract

The invention relates to a heat treatment system (1) for a vehicle, comprising a coolant circuit (2) and a heat transfer fluid loop (3), the heat transfer fluid loop (3) comprising at least one heat exchanger (12, 35) configured to dissipate heat in an air flow (18, 19), the coolant circuit (2) comprising, in this order and according to a direction of circulation of the coolant in the coolant circuit (2), at least one compression device (4), a first heat exchanger (5) which thermally couples the heat transfer fluid loop (3) with the coolant circuit (2), a device (6) for accumulation of the coolant, a first passage (8) of an internal heat exchanger (7), an expansion member (9), a second heat exchanger (10) arranged in order to be passed through by an air flow (19) external to a passenger compartment of the vehicle and a second passage (11) of the internal heat exchanger (7).

Description

technical field [0001] The field of the invention is that of thermal management systems for heating or cooling spaces or components of vehicles, in particular motor vehicles. Background technique [0002] Currently, motor vehicles are equipped with refrigerant circuits for heating or cooling various areas or components of the vehicle. This refrigerant circuit is known in particular for the thermal management of the air flow fed into the interior of a vehicle compartment equipped with such a circuit. [0003] In another application of this circuit, it is known to use it for cooling the electric energy storage device of the vehicle, said device being used to supply energy to the electric motor capable of moving the vehicle. Thus, when the electrical energy storage device is used during the operating phase, the refrigerant circuit provides energy capable of cooling the electrical energy storage device. [0004] Refrigerant circuits known hitherto are able to perform the funct...
