    [0001] BACKGROUND OF THE INVENTION The present invention relates to a refrigerant circuit, intended for example to equip a thermal conditioning device.
    [0002] The present invention relates more particularly, but not exclusively, to the thermal conditioning of a passenger compartment of a motor vehicle. Such a thermal conditioning device can for example provide the following functions: heating of an air flow, cooling or air-conditioning of the air flow, dehumidification of the air flow. There is a need to improve the efficiency of such a refrigerant circuit, particularly when it is intended to provide the heating function of a flow of air. The invention aims in particular to provide a simple, effective and economical solution to this problem. For this purpose, it proposes a refrigerant circuit comprising a first heat exchanger forming a condenser, a second heat exchanger forming a condenser or an evaporator, a third heat exchanger forming an evaporator, a compressor, a first expander, a second expander and means for redirecting the flow of refrigerant capable of circulating the refrigerant according to a first operating mode in which the refrigerant circulates in a first through loop at least successively the compressor, the first heat exchanger, the second heat exchanger then forming a condenser, the second expander, and the third heat exchanger before crossing the compressor again.
    [0003] The circuit can be designed so that, in the first mode of operation, the refrigerant from the first heat exchanger passes through the first expander before passing through the second heat exchanger. Furthermore, the refrigerant may be able to circulate according to: a second mode of operation in which the refrigerant circulates in a second loop at least successively passing through the compressor, the first heat exchanger, the first expander, the second exchanger heat then forming an evaporator and the third heat exchanger before passing through the compressor again, and / or a third mode of operation in which the refrigerant circulates in a first loop at least successively passing through the compressor, the first exchanger heat, the first expander, and the second heat exchanger then forming an evaporator before crossing the compressor again. The circuit may be designed so that in the second mode of operation the refrigerant from the second heat exchanger passes through the second expander before passing through the third heat exchanger. The first heat exchanger is for example capable of exchanging heat between the refrigerant and the coolant of a coolant circuit. The heat transfer fluid circuit may comprise a first radiator capable of exchanging heat between said heat transfer fluid and air outside a vehicle and a second radiator able to exchange heat between said heat transfer fluid and an air flow 25 intended for to unclog in a passenger compartment of the vehicle, the heat transfer fluid circuit further comprising means for redirecting the coolant capable of directing the heat transfer fluid to the first radiator and / or to the second radiator. The second heat exchanger may be adapted to exchange heat between the refrigerant and the air flow intended to open into the passenger compartment. The third heat exchanger may be adapted to exchange heat between the refrigerant and air outside the vehicle. In such a configuration, which is only one exemplary embodiment, and in the first mode of operation, called the cabin heating mode, calories can be taken from the outside air, using the third heat exchanger, said calories being then transferred to the flow of air intended for the passenger compartment (heating of the passenger compartment), both directly by the second heat exchanger and indirectly by means of the first heat exchanger , heat transfer fluid and the second radiator. In this mode of operation, it is therefore possible to increase the amount of heat supplied to the air flow intended for the passenger compartment and / or to reduce the consumption of the compressor which must provide only a reduced work in order to reach a set point with regard to the temperature of the passenger compartment.
    [0004] It will also be noted that, in this mode of operation, the quantity of heat transmitted indirectly (via the heat transfer fluid circuit) to the flow of air intended to open into the passenger compartment is relatively small, which makes it possible to improve the performance of the device. Indirect heat transmission has a lower efficiency than direct heat transfer. Such a mode of operation can be used in particular in the case where the temperature of the air outside the vehicle is relatively low, for example negative. In the second mode of operation, called the dehumidification mode, calories can be taken from the outside air, using the third heat exchanger, calories also being taken from the air flow intended for the passenger compartment, using the second heat exchanger, so as to condense the moisture contained in the air flow intended for the passenger compartment (dehumidification). The calories thus collected can then be transferred to the heat transfer fluid via the first heat exchanger, then to the air flow intended for the passenger compartment (previously dehumidified by the second heat exchanger), using the second radiator. . Such a mode of operation can be used in particular in the case where the temperature of the air outside the vehicle is positive, for example between 3 and 15 ° C. In the third mode of operation also called air conditioning mode of the passenger compartment, calories can be taken from the flow of air intended for the passenger compartment (cooling or air conditioning of the air intended for the passenger compartment) using the second heat exchanger, said calories being transferred to the heat transfer fluid through the first heat exchanger. These calories are then vented to the outside air via the first radiator. It will be noted that the architecture proposed by the invention makes it possible to improve the efficiency of the refrigerant circuit, in particular for the first mode of operation, without the addition of a heat exchanger, an expander or a valve. According to a characteristic of the invention, the circuit comprises an accumulator situated upstream of the compressor. The means for redirecting the flow of refrigerant may comprise a non-return valve located downstream of the third heat exchanger. Furthermore, the device may comprise: a first portion forming a loop extending from the compressor outlet to the inlet of the compressor and comprising successively the first heat exchanger, the first expander, the second heat exchanger, a first branch and a second branch, - a second portion extending from the first branch to the second branch and comprising successively, from the first branch to the second branch, the second expander and the third heat exchanger, - the means for redirecting the flow of refrigerant being able to allow the passage of refrigerant in the first portion, between the first and second branch, while prohibiting the passage of refrigerant in the second portion, or able to allow the passage of refrigerant in the second portion while by prohibiting the passage of refrigerant in the first portion, between the first and second branches. In this case, the first portion may comprise a first stop valve located between the first and second branches, the second portion having a second stop valve located between the first branch and the second expansion valve, the first stop valve and the second shut-off valve belonging to the means for redirecting the flow of refrigerant. Alternatively, the two shut-off valves may be replaced by a three-way valve located at the first branch. The second portion may include a non-return valve located between the third heat exchanger and the second branch, the non-return valve belonging to the means for redirecting the flow of refrigerant.
    [0005] Furthermore, the first expander and / or the second expander have a variable opening or pressure drop, the opening and / or the pressure drop of the first expander and / or the second expander being controlled. Thus, in the first mode of operation, the first expander can be completely open and have a zero pressure drop. In the second mode of operation, the second expander can be completely open and have a zero pressure drop. In each of these different modes of operation, it is also possible to bypass the regulator concerned, for example by means of a bypass portion.
    [0006] In addition, the first heat exchanger can be adapted to exchange heat with a heat transfer fluid of a heat transfer fluid circuit. The invention also relates to a device for thermal conditioning of a space, comprising a refrigerant circuit of the aforementioned type, characterized in that the first heat exchanger is able to exchange heat between the refrigerant and the heat transfer fluid of the heat transfer fluid circuit, said heat transfer fluid circuit comprising a first radiator capable of exchanging heat between said heat transfer fluid and air outside said space and a second radiator able to exchange heat between said heat transfer fluid and a heat transfer fluid. air intended to open into said space, the heat transfer fluid circuit further comprising means for redirecting the heat transfer fluid capable of directing the heat transfer fluid to the first radiator and / or to the second radiator, the second heat exchanger being adapted to exchanging heat between the refrigerant and the flow of air intended to emerge in said air ace, the third heat exchanger being able to exchange heat between the refrigerant and air outside said space. According to a possible characteristic of the invention, the means of redirection of the coolant circuit can be designed to direct the heat transfer fluid to the first radiator in the first operating mode and to direct the heat transfer fluid to the second radiator in the second mode of operation and in the third mode of operation.
    [0007] The invention also relates to a motor vehicle comprising a thermal conditioning device of the aforementioned type, said space being a passenger compartment of the motor vehicle. The invention finally relates to a method of operating a refrigerant circuit comprising a first heat exchanger 30 forming a condenser, a second heat exchanger forming a condenser or an evaporator, a third heat exchanger forming an evaporator, a compressor , a first expander, a second expander and means for redirecting the flow of refrigerant, characterized in that it comprises at least one step of redirecting the flow of refrigerant according to one of the following operating modes: - a first mode of operation in which the refrigerant circulates in a first through loop at least successively the compressor, the first heat exchanger, the second heat exchanger then forming a condenser, the second expander, and the third heat exchanger before crossing again the compressor, - a second mode of operation in which the refrigerant circulates in a second loop at least successively passing through the compressor, the first heat exchanger, the first expander, the second heat exchanger then forming an evaporator and the third heat exchanger before crossing the compressor again, - a third mode of operation in which the refrigerant circulates in a first loop at least successively passing the compressor, the first heat exchanger, the first expander, and the second heat exchanger then forming an evaporator before passing through the compressor again.

    [0008] Figure 1 illustrates a thermal conditioning device of a passenger compartment of a motor vehicle. This comprises a refrigerant circuit comprising a first heat exchanger 1 forming a condenser, a second heat exchanger 2 forming a condenser or evaporator (also called evapo-condenser), a third heat exchanger 3 forming an evaporator, a compressor C, a first expander D1, a second expander D2, a first shutoff valve V1, a second shutoff valve V2, a check valve AR and an accumulator A. The first expander D1 and the second expander D2 are variable opening or variable pressure drop, said opening or said pressure drop being adapted to be controlled by means of control means not shown. More particularly, the refrigerant circuit comprises: a first portion P1 forming a loop extending from the outlet of the compressor C to the inlet of the compressor C and comprising, successively, the first heat exchanger 1, the first expander D1, the second heat exchanger 2, a first branch E1, the first gate V1, a second branch E2, and the accumulator A; a second portion P2 extending from the first branch E1 to the second branch E2 and comprising, successively, the first branch El to the second branch E2, the second valve V2, the second expansion valve D2, the third heat exchanger 3 and the nonreturn valve AR. The first heat exchanger 1 is able to exchange heat between the refrigerant and the heat transfer fluid of a coolant circuit. The heat transfer fluid circuit comprises a first radiator R1 capable of exchanging heat between said heat transfer fluid and air outside the vehicle and a second radiator R2 capable of exchanging heat between said heat transfer fluid and an air flow for to unblock in the passenger compartment of the vehicle. The heat transfer fluid circuit further comprises a pump P and valves V3, V4 capable of directing the heat transfer fluid to the first radiator R1 and / or to the second radiator R2. Of course, the structure of the coolant circuit is only an exemplary embodiment and it is possible to use other equivalent structures (use of one or more three-way valves, for example) to ensure the same functions. The second heat exchanger 2 is able to exchange heat between the refrigerant and the air flow intended to open into the passenger compartment. The third heat exchanger 3 is able to exchange heat between the refrigerant and the air outside the vehicle.
    [0009] The second heat exchanger 2 and the second radiator R2 are for example arranged in an air flow channel of a heating, ventilation and / or air conditioning system, also called H.V.A.C. (Heating, Ventilation and Air-Conditioning, in English), said channel being intended to open into the passenger compartment of the vehicle. The first radiator R1 and the third heat exchanger 3 are for example arranged on the front face of the vehicle.
    [0010] FIG. 2 illustrates a first mode of operation of the device according to the invention, in which the first valve V1 is closed and in which the second valve V2 is open. Thus, the refrigerant circulates in a first through loop at least successively the compressor C, the first heat exchanger 1, the first expander D1, the second heat exchanger 2 then forming a condenser, the second valve V2, the second expander D2 , the third heat exchanger 3, the nonreturn valve AR and the accumulator A before crossing the compressor C again.
    [0011] In this operating mode, the expansion valve D1 and the expander D2 are not completely open and consequently apply a pressure drop. In this mode of operation also, the first radiator R1 is rendered inoperative by closing the valve V3. The heat transfer fluid circulates only through the second radiator R2. In the first mode of operation, called cabin heating mode, calories can be taken from the outside air, using the third heat exchanger 3, said calories then being transferred to the air flow intended for the cabin (heating of the passenger compartment), both directly by the second heat exchanger 2 and indirectly with the aid of the first heat exchanger 1, the coolant and the second radiator R2. In this operating mode, it is therefore possible to increase the amount of heat supplied to the air flow intended for the passenger compartment and / or to reduce the consumption of the compressor C which must provide only a reduced work in order to to reach a set point with regard to the temperature of the passenger compartment. Note also that, in this mode of operation, the amount of heat transmitted indirectly (through the coolant circuit) to the flow of air to open into the passenger compartment is low, which improves the performance of the device. Indirect heat transmission has a lower efficiency than direct heat transfer. Such a mode of operation can be used in particular in the case where the temperature of the air outside the vehicle is relatively low, for example negative. The thermodynamic cycle corresponding to the first mode of operation is illustrated in the Mollier diagram of FIG. 3. In this diagram, points referenced 11 to 17 have been reported both on the Mollier diagram and on the illustrated refrigerant circuit. in Figure 2 to facilitate understanding. The phases of the refrigerant (liquid, diphasic, that is to say liquid and vapor, steam) are also indicated on the diagram, as well as the different stages of the cycle (evaporation, condensation, compression, expansion). Note that the point i3 may optionally be located in the zone corresponding to the two-phase state, since the second heat exchanger 2 then ensures the condensation of the refrigerant. It is then possible to reduce the size of the second radiator R2 without affecting the proper operation of the device. FIG. 4 illustrates a variant of the first mode of operation, which differs from that described with reference to FIGS. 2 and 3 in that the first expander D1 is completely open and therefore does not apply any pressure drop. As before, the thermodynamic cycle corresponding to this variant of the first mode of operation is illustrated in the Mollier diagram of FIG. 5. In this diagram, points referenced 11 to 17 have been reported both on the Mollier diagram and on the refrigerant circuit illustrated in Figure 4 to facilitate understanding. Note that the points i3 and i4 are merged on the Mollier diagram, since the second expander D2 applies no pressure drop.
    [0012] FIG. 6 illustrates a second mode of operation in which the valve V1 is closed and in which the valve V2 is open. Thus, the refrigerant circulates in a second loop through at least successively the compressor C, the first heat exchanger 1, the first expander D1, the second heat exchanger 2 then forming an evaporator, the second valve V2, the second expander D2 , the third heat exchanger 3, the nonreturn valve AR and the accumulator A before going through the compressor C again. In this operating mode, the pressure reducer D1 applies a pressure drop, but the regulator D2 is completely closed. open and therefore does not apply pressure drop. In this mode of operation also, the first radiator R1 is rendered inoperative by closing the valve V3. The heat transfer fluid circulates only through the second radiator R2.
    [0013] In the second mode of operation, called the dehumidification mode, calories can be taken from the outside air, using the third heat exchanger 3, calories also being taken from the air flow intended for the cabin, using the second heat exchanger 2, so as to condense the moisture contained in the air flow to the passenger compartment (dehumidification). The calories thus collected can then be transferred to the heat transfer fluid via the first heat exchanger 1, then to the flow of air intended for the passenger compartment (previously dehumidified by the second heat exchanger 2), using the second radiator R2.
    [0014] Such a mode of operation can be used in particular in the case where the temperature of the air outside the vehicle is positive, for example between 3 and 15 ° C. As before, the thermodynamic cycle corresponding to the second mode of operation is illustrated in the Mollier diagram of FIG. 7. In this diagram, points referenced 11 to 17 have been reported both on the Mollier diagram and on the circuit. of refrigerant shown in Figure 6 for ease of understanding. Note that the points i5 and i6 are merged on the Mollier diagram, since the first regulator D1 does not apply any pressure drop. FIG. 8 illustrates a third mode of operation in which the valve V1 is open and in which the valve V2 is closed. Thus, the refrigerant circulates in a first loop passing at least successively the compressor C, the first heat exchanger 1, the first expander DI, the second heat exchanger 2 then forming an evaporator, the first valve V1 and the accumulator A before going through compressor C again. In this operating mode, the pressure reducer D1 applies a pressure drop. In this mode of operation also, the second radiator R2 is rendered inoperative by closing the valve V4. The heat transfer fluid circulates only through the first radiator R1. In the third mode of operation, also called air conditioning mode of the passenger compartment, calories can be taken from the flow of air intended for the passenger compartment (cooling or air conditioning of the air intended for the cabin) to the using the second heat exchanger 2, said calories being transferred to the heat transfer fluid through the first heat exchanger 1. These calories are then discharged into the outside air, through the first radiator Rl. As before, the thermodynamic cycle corresponding to the third mode of operation is illustrated in the Mollier diagram of FIG. 9. In this diagram, points referenced il to i5 have been reported both on the Mollier diagram and on the control circuit. refrigerant shown in Figure 8 for ease of understanding.
