    [0001] 1 Intake air thermal management system of a supercharged engine. The present invention relates to a thermal air management system 5 intake of a supercharged engine. It is known in the field of supercharged engine vehicles to equip the intake air circuit with a charge air cooler disposed within a thermal management loop comprising a pump and a radiator for evacuate the heat energy captured by the charge air cooler. Nevertheless, under certain conditions, especially when the outside temperature is high, the radiator can not evacuate enough heat energy and the intake air thus sees its temperature increase. To overcome this problem it is also known to add an additional heat exchanger within the air intake circuit. This additional heat exchanger is connected to a cold source, such as an air conditioning circuit. However, such an additional heat exchanger within the air intake circuit results in a pressure drop of the intake air which can adversely affect the performance of the engine. In addition, an additional heat exchanger within the air intake circuit is difficult and expensive to integrate. It is therefore an object of the present invention to at least partially overcome the disadvantages of the prior art and to provide an improved intake air thermal management system. The present invention relates to a thermal management system (1) of intake air, comprising a thermal management loop (A) of intake air of a supercharged thermal engine in which circulates a heat transfer fluid, an air conditioning loop (B) operable in an air conditioning mode and in which a refrigerant circulates, said air conditioning loop (B) comprising a compressor (33), a first and a second heat exchanger (35, 39) and an expansion member (37), said admission air thermal management system (1) also comprising a bifluid exchanger (9) in which the cooling fluid and the heat transfer fluid circulates, said thermal management loop (A) comprising a charge air cooler (5) and a radiator (7), the bifluid exchanger (9) being arranged upstream of the charge air cooler (5) of said thermal management loop (A) and the low pressure side of the said air conditioning loop (B) in air conditioning mode, said thermal management loop (B) further comprising a bypass branch (11) of said two-fluid heat exchanger (9) and a device for redirecting (13) the heat transfer fluid to said bypass branch (11) of the two-fluid heat exchanger (9) or to the two-fluid heat exchanger (9).
    [0002] This positioning of the low pressure side thus makes it possible to cool the coolant circulating in the thermal management loop, when the air conditioning loop operates in air conditioning mode, by transfer of heat energy from the heat transfer fluid to the cooling fluid, which evaporates. at the bifluid heat exchanger. The use of a two-fluid heat exchanger to thermally manage the heat transfer fluid and thus to indirectly manage the temperature of the intake air, makes it possible to avoid using a dedicated heat exchanger within the intake circuit. of air which could increase the losses of loads and also undergo a corrosion and a fall of its performances. In addition the risks of condensation during cooling of the intake air are reduced. The integration of a two-fluid heat exchanger between the thermal management loop and the air conditioning loop is also easier than the integration of a dedicated heat exchanger within the air intake circuit.
    [0003] According to one aspect of the invention, within the air conditioning loop, the bifluid heat exchanger is connected in series with the second heat exchanger, upstream or downstream of said second heat exchanger.
    [0004] According to another aspect of the invention, within the air conditioning loop, the bifluid heat exchanger is connected in parallel with the second heat exchanger. According to another aspect of the invention, the air conditioning loop comprises a device for bifurcating the fluid towards the second heat exchanger and / or to the two-fluid heat exchanger. According to another aspect of the invention, the air-conditioning loop is a reversible air conditioning loop able to operate in a heat pump mode and in which the refrigerant circulates, said air conditioning loop comprising the compressor, a third heat exchanger , a second expansion member and the first heat exchanger, the bifluid heat exchanger then being disposed on the high pressure side of the reversible air conditioning loop during operation in heat pump mode, parallel to the third heat exchanger.
    [0005] This positioning of the high pressure side when the air conditioning loop operates in heat pump mode, thus allows the heat transfer fluid circulating in the thermal management loop to be heated when the air conditioning loop operates in heat pump by transfer of heat energy since the coolant, which condenses at the bifluid heat exchanger, to the coolant. According to another aspect of the invention, the refrigerant circulating in the air conditioning loop circulates successively in the compressor, the third heat exchanger, the second expansion member and the first heat exchanger.
    [0006] According to another aspect of the invention, the air-conditioning loop comprises: a bifurcation device allowing the redirection of the refrigerant fluid from the expansion element situated between the first and the second heat exchanger towards the two-fluid heat exchanger and / or the redirection of the refrigerant fluid from the compressor to the two-fluid heat exchanger, - a bifurcation device for redirecting the refrigerant fluid from the two-fluid heat exchanger to the compressor and / or to the first heat exchanger. According to another aspect of the invention, the thermal management loop further comprises a thermal battery.
    [0007] According to another aspect of the invention, the thermal battery is disposed on the bypass branch of the two-fluid heat exchanger. According to another aspect of the invention, the thermal battery is arranged parallel to the bifluid heat exchanger. According to another aspect of the invention, the thermal battery comprises a phase change material.
    [0008] According to another aspect of the invention, the thermal management loop includes a bypass branch of the radiator. Other features and advantages of the invention will emerge more clearly on reading the following description, given by way of illustrative and nonlimiting example, and the appended drawings in which: FIG. 1 shows a diagrammatic representation of a heat management system of admission air according to a first embodiment, - Figure 2 shows a schematic representation of an intake air thermal management system according to a second embodiment, 5 - FIG. 3 shows a schematic representation of a thermal management loop of an intake air thermal management system according to a particular embodiment; FIG. 4 shows a schematic representation of a thermal management loop of an intake air thermal management system according to an alternative embodiment; FIG. 5 shows a diagrammatic representation of an air thermal management system; According to a third embodiment, FIGS. 6 and 7 show representations of the thermal management system of FIG. 5 according to different modes of operation.
    [0009] In the different figures, the identical elements bear the same reference numbers.
    [0010] In the present description it is possible to index certain elements or parameters, such as for example first element or second element as well as first parameter and second parameter, or first criterion and second criterion, and so on. In this case, it is a simple indexing to differentiate and name elements or parameters or criteria close but not identical. This indexation does not imply a priority of one element, parameter or criterion with respect to another, and it is easy to interchange such denominations without departing from the scope of the present description. This indexing does not imply either an order in time for example to appreciate such or such criteria.
    [0011] 3036744 6 In this description we will talk about "connection points" and "junction points". These elements are in both cases elements having the same function of node and can have the same structure. For the sake of clarity, their denomination differs in order to identify those present on the thermal management loop 5 A as "connection points" and those present on the air conditioning loop B as "junction points". This name can be inverted without departing from the scope of the present invention. In the present description we will also speak of "redirection devices" and "bifurcation devices". These elements are in both cases elements having the same function of orientation of the fluid and can have the same structure. For the sake of clarity, their denomination differs in order to identify those present on the thermal management loop A as "redirection devices" and those present on the air conditioning loop B as "bifurcation devices". This denomination can be inverted without departing from the scope of the present invention. In the present description, the term "placed upstream" means that one element is placed before another relative to the direction of flow of a fluid. On the other hand, "downstream" means that one element is placed after another relative to the direction of circulation of the fluid. As shown in FIG. 1, the intake air thermal management system 1 comprises an intake air thermal management loop A, in which a heat transfer fluid circulates, this thermal management loop A comprises in particular: - a pump 3, - a charge air cooler 5, - a radiator 7, 3036744 7 - a bifluid heat exchanger 9, arranged upstream of the charge air cooler 5, and in which also circulates a cooling fluid from an air conditioning loop B, - a bypass branch 11 of said two-fluid heat exchanger 9, said bypass branch 11 connecting a first connection point 101 placed upstream of the bifluid heat exchanger 9 and a second point connection piece 102 disposed downstream of the bifluid heat exchanger 9, - a device for redirecting the fluid 13 to said connecting branch 11 of the bifluid heat exchanger 9 or to the dual heat exchanger fluid 9, 10 disposed on the first connection point 101. This redirection device 13 may be for example a three-way valve 13 disposed on the first connection point 101 as shown in Figures 1 to 5. 11 is however quite it is possible to imagine other configurations of the redirection device 13 such as for example a configuration composed of two valves arranged respectively between the first connection point 101 and the two-fluid heat exchanger 9 and on the bypass branch 11 of said heat exchanger. Bifluid heat 9. In the rest of the description, the redirection and bifurcation devices given as examples will be three-way valves. In the same way, it will be possible to imagine for each device a configuration composed of two valves. The bypass branch 11 of the bifluid heat exchanger 9 and the redirection device 13 make it possible to choose whether or not the heat transfer fluid of the thermal management loop A passes through the bifluid heat exchanger 9 and therefore if this latter influences or not on the temperature of said coolant through the coolant of the air conditioning loop B. The air conditioning loop B comprises in particular: - a compressor 33, 3036744 8 - a first heat exchanger 35, generally disposed in a external air flow, in particular on the front face of the motor vehicle, an expansion member 37, a second heat exchanger 39, generally disposed in a flow of air intended for the passenger compartment of the motor vehicle, in particular at the in a heating, ventilation and air conditioning (or HVAC) room. The air-conditioning loop B is capable of operating in an air conditioning mode, that is to say that the refrigerant circulates successively in the compressor 33, the first heat exchanger 35, the expansion device 37 and the second heat exchanger 39. The bifluid heat exchanger 9 is disposed on the low pressure side of said air conditioning loop B, when the latter operates in air conditioning mode. By "low pressure" it is meant that the refrigerant flowing through the bifluid heat exchanger 9 has been expanded at an expansion member. This positioning of the low pressure side thus makes it possible to cool the coolant circulating in the thermal management loop A, when the air conditioning loop B operates in air conditioning mode, by transfer of heat energy from the coolant to the coolant, which evaporates at the level of the two-fluid heat exchanger 9. The use of a bifluid heat exchanger 9 to thermally manage the coolant and therefore to indirectly manage the temperature of the intake air, allows avoid using a dedicated heat exchanger within the air intake system which could increase the pressure losses and also suffer corrosion and a decrease in its performance. In addition the risks of condensation during cooling of the intake air are reduced. The integration of a bifluid heat exchanger 9 between the thermal management loop A and the air conditioning loop B is also easier than the integration of a dedicated heat exchanger within the air intake circuit. .
    [0012] According to a first embodiment illustrated in FIG. 1, the bifluid heat exchanger 9 is connected in series with the second heat exchanger 39. The bifluid heat exchanger 9 can thus be disposed downstream of the second heat exchanger 39. heat exchanger 39 between said second heat exchanger 39 and the compressor 33. The bifluid heat exchanger 9 can also be disposed upstream of the second heat exchanger 39, between the latter and the first expansion member 37. According to a second embodiment 2, the bifluid heat exchanger 9 is connected in parallel with the second heat exchanger 39. The refrigerant fluid inlet of the bifluid heat exchanger 9 is then connected to a first junction point. 201 disposed upstream of the second heat exchanger 39 and the refrigerant outlet of the two-fluid heat exchanger 9 is connected to a second junction point 202 disposed downstream of the second heat exchanger 39.
    [0013] The air-conditioning loop B comprises a bifurcation device 43 for the fluid towards the second heat exchanger 39 and / or to the two-fluid heat exchanger 9. This bifurcation device 43 may be for example a three-way valve 43 arranged on the first junction point 201 ..
    [0014] As shown in FIGS. 3 and 4, the admission air thermal management circuit A may also include a thermal battery 15. The thermal battery 15 may in particular comprise a phase-change material. This thermal battery 15 may be connected in parallel with the bifluid heat exchanger 9 as illustrated in FIG. 3. The thermal battery 15 is then placed between a third connection point 103 placed between the two-fluid heat exchanger 9 and the first connection point 101, and a fourth connection point 104, placed between said two-fluid heat exchanger 9 and the second connection point 102. This placement of the thermal battery 15 allows the latter also to be bypassed by the bypass branch 11 of the two - fluid heat exchanger 9.
    [0015] The thermal battery 15 may also be arranged directly on the bypass branch 11 of the two-fluid heat exchanger 9, as illustrated in FIG. 4. The presence of a thermal battery 15 within the thermal management loop 5 A may, depending on the type of thermal battery 15 chosen, store heat energy in order to heat the heat transfer fluid, for example during a cold start, or to allow cooling of the heat transfer fluid by capturing the heat transfer fluid. heat energy of the heat transfer fluid, without the need to start the air conditioning branch B, for example during a rapid acceleration phase.
    [0016] The heat management circuit A for intake air may also comprise a bypass branch 17 of the radiator 7 as shown in FIG. 4. This bypass branch 17 of the radiator 7 connects a fifth connection point 105, disposed between the charge air cooler 5 and the radiator 7, and a sixth connection point 106, disposed between the radiator 7 and the first connection point 101. The thermal management loop A then comprises a second fluid redirector device 19 to the radiator 7 or to the sixth connection point 106. Like the redirection device 13, the second redirection device 19 may be for example a three-way valve 19 disposed on the fifth connection point 105. air conditioning loop B can also be a reversible air-conditioning loop, as shown in FIG. 5. By reversible air-conditioning loop, it is meant that said air-conditioning loop air conditioning B can cool as well as warm the airflow to the passenger compartment. The air-conditioning loop B may thus further comprise a condenser loop 45 between a third junction point 203 disposed downstream of the compressor 33 and a fourth junction point 204 disposed between the third junction point 203 and the first heat exchanger 35. Said condenser loop 45 comprises in particular: a third heat exchanger 41, generally disposed in a flow of air to the passenger compartment of the motor vehicle, in particular in a heating, ventilation and air-conditioning chamber; a second expansion member 49 disposed downstream of said third heat exchanger 41. The air conditioning loop B comprises a bifurcation device 52 for the fluid towards the second heat exchanger 39 and / or to the third heat exchanger 41. bifurcation device 52 of the fluid to the second heat exchanger 39 and / or to the third heat exchanger 41 may be for example a three-way valve 52 disposed on the third junction point 203. The air conditioning loop B, in order to be a reversible air conditioning loop, also comprises a bypass branch 56 of both the first expansion member 37 and the second heat exchanger 39. This bypass branch 56 connects a fifth junction point 205, disposed between the first heat exchanger 15 and the first expansion member 37, and a sixth junction point 206 disposed between the second heat exchanger 39 and the compressor 33. The air conditioning loop B also comprises a bifurcation device 53 of the fluid to the first expansion member 37 and / or to the compressor 33. This bifurcation device 53 of the fluid to the first expansion member 37 and or to the compressor 33 may be for example a three-way valve 53 disposed on the fifth junction 205. In this configuration, the air conditioning loop Reversible B is still able to operate in its cooling mode, ie where the refrigerant circulates successively in the compressor 33, the first heat exchanger 35, the expansion member 37 and the second heat exchanger 39 as shown in FIG. 6. For this, the bifurcation device 52 redirects the fluid to the first heat exchanger 35 and the bifurcation device 53 redirects the refrigerant to the expansion member 37 3036744 12 The air conditioning loop B reversible is also able to operate in a heat pump mode, that is to say that the refrigerant circulates successively in the compressor 33, the third heat exchanger 41, the second expansion member 49 and the first heat exchanger 35. This mode of operation is illustrated in FIG. 7. For this, the bifurcation device 52 redirects the fluid to the third heat exchanger 41 and the bifurcation device 53 redirects the refrigerant to the compressor 33. In this heat pump mode, the bifluid heat exchanger 9 is disposed on the high pressure side of said air conditioning loop B. By "high pressure side" is meant that the refrigerant has not yet undergone expansion after passing through the compressor 33. This positioning of the high pressure side when the air conditioning loop operates in heat pump mode, thus allows to heat the coolant flowing in the loop of thermal management A when the air-conditioning loop B operates as a heat pump by transferring heat energy from the cooling fluid, which condenses at the level of the two-fluid heat exchanger 9, to the coolant, as illustrated in FIG. 7. In order to ensure these two coolant cooling functions 20 when the air conditioning loop B is in cooling mode ( illustrated in FIG. 6) and heating of the coolant when the air conditioning loop A is in heat pump mode (illustrated in FIG. 7), the bifluid heat exchanger 9 is connected in parallel with both of the second heat exchanger. heat 39 and the third heat exchanger 41. The refrigerant inlet of the bifluid heat exchanger 9 is thus connected to the first junction point 201 and to a seventh junction point 207 disposed on the upstream condenser loop 45 the third heat exchanger 41. This connection is enabled by a bifurcation device 54 which allows the redirection of the refrigerant from the expansion member 37 to the bifluid heat exchanger 9 and / or allows to redirect the refrigerant from the compressor 30 33 to the two-fluid heat exchanger 9 3036744 13 The refrigerant output of the bifluid heat exchanger 9 is connected to it at the second junction point 202 and at an eighth junction point 208 disposed on the condenser loop 45 downstream of the third heat exchanger 41. This connection is enabled by a bifurcation device 55 for redirecting the coolant from the Bifluid heat exchanger 9 to the compressor 33 or to the first heat exchanger 35. The heat management circuit A for intake air can thus operate according to several operating modes, dependent on the path of the heat transfer fluid, 10 which: - a so-called standard mode where the heat transfer fluid passes in the pump 3, the charge air cooler 5 and the radiator 7. In this so-called standard mode, the redirection device 13 allows the bypass of the two-fluid heat exchanger 9 and the thermal battery 15, if present. If the bypass branch 17 of the radiator 7 is present, the second redirection device 19 redirects the coolant to the radiator 7. - a so-called restricted mode where the heat transfer fluid passes into the pump 3, the charge air cooler 5 and the thermal battery 15. In this so-called restricted mode, the redirection device 13 allows the bifluid heat exchanger 9 to be bypassed and redirects the coolant towards the thermal battery 15. The bypass branch 17 of the radiator 7 being present, the second redirector device 19 redirects the heat transfer fluid to the bypass branch 17. - a so-called intermediate mode where the heat transfer fluid passes in the pump 3, the charge air cooler 5, the bifluid heat exchanger 9 and the thermal battery 15. In this intermediate mode, the redirection device 13 redirects the heat transfer fluid to the two-fluid heat exchanger 9 and the thermal battery 15. The bypass branch 17 of the radiator 7 being present, the second redirector device 19 redirects the heat transfer fluid to the bypass branch 17. A complete mode in which the heat transfer fluid passes into the pump 3 , the charge air cooler 5, the radiator 7 and the bifluid heat exchanger 9 and the thermal battery 15. In this so-called complete mode, the redirection device 13 redirects the heat transfer fluid to the two-fluid heat exchanger 5 9 and the thermal battery 15. If the bypass branch 17 of the radiator 7 is present, the second redirector device 19 redirects the coolant to the radiator 7. When the air conditioning loop B is in cooling mode, the operating modes intermediate or complete are preferably used when it is inexpensive energy to operate the compressor 33, for example during phases of decelerated braking, or when the air conditioning loop B has a high coefficient of performance and where the cooling of the heat transfer fluid does not affect the comfort of the occupants of the motor vehicle, this is for example the case 15 during motorway journeys or in the optimal operating range of the thermal engine. The bifluid heat exchanger 9 because it is placed on the low pressure side of the air conditioning loop B in cooling mode, allows cooling of the heat transfer fluid of the thermal management loop A and thus said air conditioning loop B in cooling mode can help cooling the air of overfeeding. The restricted mode of operation can also be used to cool the intake air through the thermal battery 15 without the need to pass through the radiator 7 and the two-fluid heat exchanger 9. L The heat energy stored in the thermal battery 15 during this cooling can then be evacuated during the standard operation of the thermal management loop A or by means of the air conditioning loop B in cooling mode. Conversely, the restricted mode of operation can be used to heat the intake air via the thermal battery 15. This heating of the intake air 30 can help the engine to reach its optimum temperature. 3036744 15 operation faster. The heat energy released by the thermal battery 15 during this heating can then be recovered during the standard operation of the thermal management loop A or through the air conditioning loop B in heat pump mode.
    [0017] When the air conditioning loop B is in heat pump mode, the intermediate or complete operating mode is preferably used during cold start. The bifluid heat exchanger 9 because it is placed on the high pressure side of the air conditioning loop B in heat pump mode, allows heating of the coolant 10 of the thermal management loop A and therefore said air conditioning loop B in heat pump mode can help heat the intake air and thus help the heat engine to reach its optimum operating temperature faster.
    [0018] Thus, it can clearly be seen that the thermal management system 1, particularly because of the use of a bifluid heat exchanger 9 and its positioning, allows improved management of the temperature of the intake air. 20
