Definitions
- the refrigerant circuit includes a first portion which includes at least the compression device, the first heat exchanger, the coolant accumulation device, and a second portion which includes the first expansion device and the second heat exchanger arranged to be traversed by an interior air flow sent into the passenger compartment of the vehicle.
- the branch which includes the second expansion device and a third heat exchanger is in parallel with the second portion, seen from the point of view of the refrigerant.
- the refrigerant circuit comprises a point of divergence where the branch begins, as well as a point of convergence where said branch ends, the refrigerant circuit comprises a first internal heat exchanger of which at least one pass is disposed between an outlet of the second heat exchanger and the point of convergence.
- the first internal heat exchanger is active only with regard to the refrigerant which is sent to the second heat exchanger.
- the refrigerant circuit can include a second valve for controlling the circulation of refrigerant in the pipeline.
- the heat exchanger of the heat transfer liquid loop is an air heater arranged to be traversed by the internal air flow sent into the passenger compartment of the vehicle.
- FIG. 3 is a schematic view of the heat treatment system, in a third embodiment
- the figures show the invention in detail in order to implement the invention, said figures possibly of course serve to better define the invention, if applicable.
- These figures are schematic representations which illustrate how the heat treatment system is made, what makes it up and how the fluids circulate within it.
- the heat treatment system comprises on one side a refrigerant circuit and a loop of heat transfer liquid, a heat exchanger being traversed by these two fluids.
- This refrigerant circuit 2 is a closed loop where the refrigerant is circulated by a compression device 4.
- this compression device 4 can take the form of an electric compressor, that is to say a compressor which includes a compression mechanism, a electric motor and possibly a controller. The rotation mechanism is rotated by the electric motor, the rotation speed of which is under the control of the controller, which can be external or internal to the compression device.
- the refrigerant circuit 2 comprises, in this order and according to the direction of circulation of the refrigerant within it, at least the compression device 4 connected by a pipe to a first exchanger heat 5 which thermally couples the loop of heat transfer liquid 3 with the refrigerant circuit 2.
- This first heat exchanger 5 is connected by a pipe to a storage device 6 of the refrigerant.
- this accumulation device 6 is thus arranged for example immediately downstream of the first heat exchanger 5, and it can for example take the form of a desiccant bottle. We will see from the description of Figure 5 that the positioning of this accumulation device 6 can change, without departing from the scope of the invention.
- the storage device 6 is then directly connected to an internal heat exchanger 26, in particular to a first pass 27 of this internal heat exchanger 26.
- This first pass 27 of the internal heat exchanger 26 is connected directly to the point of divergence 29, that is to say a point where coolant can separate into two parts.
- the refrigerant circuit 2 also comprises the first expansion device 16 which is interposed between the point of divergence 29 and the second heat exchanger 17 arranged to be crossed by an internal air flow 18 sent into the passenger compartment of the vehicle.
- FIG. 4 illustrates an alternative embodiment transposable to the third embodiment described above.
- the compression device 4 discharges the hot refrigerant into the first heat exchanger 5.
- FIG. 6 shows another alternative embodiment applicable to any one of the first, second or third embodiment illustrated respectively in FIGS. 1, 2 and 3.
- it is the common internal heat exchanger 26 which is illustrated in FIG. 6, but it is understood that the modifications set out below can be transposed to the embodiment which exploits the first internal heat exchanger and the second internal heat exchanger assigned respectively to the second portion 15 of the circuit and to the branch 20 of it.
- the refrigerant in gaseous state then leaves the second heat exchanger 17 and travels through the second pass 39 of the first internal heat exchanger 36.
- a transfer of calories occurs between the refrigerant in the liquid state present in the first pass 38 and the refrigerant in the gaseous state present in the second pass 39 of the first internal heat exchanger 36.
- the refrigerant which leaves the second pass 39 of the first internal heat exchanger 36 finally joins an inlet of the compression device 4 so that a new thermodynamic cycle can take place in the refrigerant circuit 2.
- the pump 13 is stopped, so that there is no circulation of heat transfer liquid in the first portion of the heat transfer liquid loop, between the first heat exchanger heat 5 and the first heat exchanger 12.
- the circulation means 48 is active and circulates the heat transfer liquid in the second portion of the heat transfer liquid loop, between the first heat exchanger 5 and the second heat exchanger 35, so as to discharge the calories into the external air flow 19.
- FIG. 8 illustrates an operating mode corresponding to cooling of a component of an electric traction chain of the vehicle via the additional fluid 9.
- a component is for example an electric motor for setting the vehicle in motion, a device for electrical energy storage or an electronic power module which controls in particular the electric motor set in motion.
- the behavior of the refrigerant in the first portion 14 is identical to that of FIG. 7, and reference will be made to the description of this figure for the description thereof.
- This operating mode differs from that of FIG. 7 in that the first expansion device 16 is placed in a closed position, preventing any circulation of refrigerant fluid in the second heat exchanger 17.
- FIG. 10 illustrates a mode of operation known as heating of the passenger compartment by recovery of heat energy on a component of the electric powertrain.
- the latter is used to implement the thermodynamic cycle which takes place in the refrigerant circuit 2.
- This operating mode thus makes it possible to heat the interior air flow 18 by using energy which would otherwise be lost by dissipation in the outside air flow.
- the first expansion device 16 is placed in a closed position, preventing any circulation of coolant within the second portion 15 of the coolant circuit 2.
- the control device thus acts on the speed of rotation of this compression device, in particular when it is a compressor with an integrated electric motor and with fixed displacement. It will be understood from the above that the present invention thus makes it possible to ensure simply and at optimized costs the heat treatment, by heating or cooling, of a component of the electric traction chain, such as a battery or a battery pack. , and / or the passenger compartment of the vehicle.
- the goals which the invention has set itself are achieved, by providing a heat treatment system which performs with reduced means a function of cooling the passenger compartment, a function of recovering energy on a component of the chain. of electric traction and a heat treatment function of one of the components of this electric traction chain of the vehicle.
