Definitions
- the present invention relates to a method for managing a hybrid compressor for an air conditioning circuit of a motor vehicle with a heat engine.
- the invention finds a particularly advantageous application in the field of air-conditioning of motor vehicles with a heat engine equipped with an automatic stop and start system, such as systems capable of implementing the function known as the English term saxon of "Stop and Start".
- the "Stop and Start” function is, under certain conditions, to automatically cause the complete shutdown of the engine when the vehicle itself is stopped, then automatically restart the engine after, for example, d a driver action interpreted as a restart request.
- a typical situation of implementation of the "Stop and Start” function is that of stopping at a red light.
- the "Stop" mode of the “Stop and Start” function causes the automatic shutdown of the engine, and the vehicle enters the "Start” mode, which allows the engine to restart automatically. without the need to use the initial engine starting means, such as a key contact for example.
- the "Start” mode automatically restarts the engine, in particular by means of an alternator-starter, following the detection by the control system at the start of the vehicle of the depression by the driver of the engine. clutch pedal, accelerator pedal, or any other action that may be interpreted as the driver's intention to restart the vehicle.
- an air-conditioning circuit of a heat engine vehicle comprises a refrigerant compressor which is driven by the crankshaft of the heat engine via a belt and a connected pulley. mechanically to the axis of the compressor.
- the vehicle air conditioning circuit can only operate if the engine drives the compressor. Therefore, during the phases of stopping the vehicle in the context of the "Stop and Sart" function, the compressor is no longer driven by the engine and the air conditioning stops working. As a result, during these stopping phases the set temperature inside the passenger compartment can not be maintained, which can cause a feeling of discomfort among the passengers of the vehicle.
- an object of the invention is to propose a method for managing a hybrid compressor for an air-conditioning circuit of a motor vehicle with a heat engine, said hybrid compressor being able to be driven, on the one hand, by said heat engine, and, on the other hand, by an electric motor during phases of interruption of compressor drive by the heat engine, which would make it possible to overcome the difficulty represented by the use of an electric motor of too low power opposite the resisting torque induced by the refrigerant fluid pressure variations during the shutdown of the air conditioning circuit.
- the electric motor is operated in anticipation, before the heat engine stops driving the compressor and therefore before the air conditioning circuit stops working.
- the electric motor therefore does not have to overcome its different variations of refrigerant pressure that appear in the air conditioning circuit following the shutdown. complete of the air conditioning circuit, it is then possible, without any inconvenience, to use a low power electric motor.
- This first embodiment is implemented in particular when said drive interruption is a shutdown of the engine, and, more particularly, when said shutdown of the engine is an automatic shutdown determined by an automatic shutdown and restart function of the engine. the engine of the vehicle, such as the "Stop and Start" function.
- said hybrid compressor comprises a variable displacement refrigerant fluid compression chamber comprising a single compression axis adapted to be driven by the heat engine in a higher range of displacements and by the engine in a lower range of displacements
- said method comprises steps of anticipating a phase of interruption of entramement of the axis of compression by the engine, to switch the displacement of the compression chamber of the interval greater than the lower range of displacements, and to start the electric motor before the start of the interruption of drive of the compression axis by the engine.
- the invention provides, in general, that said drive interruption is a decoupling of the heat engine from a compression axis of the hybrid compressor, and, more specifically, that the decoupling of the engine is determined by a stopping function. and of automatic restart of the engine of the vehicle, such as the "Stop and Start" function, or by a request for acceleration of the vehicle.
- the decoupling takes place between the heat engine and the first compression axis, whereas in the case of a hybrid compressor with variable displacement compression chamber, the decoupling takes place between the heat engine and the single compression axis of the chamber.
- the starting of the electric motor before the start of the interruption of the hybrid compressor drive by the engine is performed by means of detection of the stop of the engine of an automatic stop and restart function of the engine. thermal engine of the vehicle, or by means of detecting a request for acceleration of the vehicle.
- these detection means can be very varied and generally depend on the strategy chosen by the manufacturers. For example, the detection of an action on the brake pedal when the speed of the vehicle falls below a given threshold.
- Figure 2 is a diagram of an air conditioning circuit comprising a hybrid compressor of a second type.
- FIG. 3 is a diagram illustrating the operation of the hybrid compressors of FIGS. 1 and 2 for different life situations of a motor vehicle equipped with the "Stop and Start" function.
- FIG. 4 is a diagram illustrating the chronology of operation of the thermal and electrical engines of the hybrid compressors of FIGS. 1 and 2 during an automatic shutdown of the engine by the "Stop and Start" function
- a conventional air conditioning circuit of a motor vehicle with a combustion engine comprising a compressor 10 of a refrigerant which can be an organic fluid, inorganic or eutectic.
- refrigerant which can be an organic fluid, inorganic or eutectic.
- Non-limiting examples include supercritical CO 2 carbon dioxide, refrigerants known as R134A, 1234yf or GAR ("Global Alternative Refrigerant").
- the refrigerant under pressure passes through a heat exchanger 11 called "gas cooler"("GasCooler") for the carbon dioxide or “condenser” for the R134A because, in this case, the refrigerant initially in the gas phase leaves the condenser in liquid form.
- gas cooler ("GasCooler) for the carbon dioxide or "condenser” for the R134A because, in this case, the refrigerant initially in the gas phase leaves the condenser in liquid form.
- the exchanger 11 may be a water exchanger, or an air exchanger cooled directly by the outside air.
- the refrigerant is then passed to a pressure reducer 12 so that it is cooled before entering the evaporator 13, where heat exchange takes place between the cooled refrigerant and the air drawn towards the passenger compartment of the vehicle. .
- the refrigerant, heated at the outlet of the evaporator 13, is then returned to the compressor 10 to perform a new thermal cycle.
- the compressor 10 of FIG. 1 is a hybrid compressor of the type with two separate compression chambers, namely, on the one hand, a first chamber 101 having a first compression axis 111 suitable for to be driven by the crank shaft of the engine (not shown) of the vehicle via a belt and a pulley 30 mechanically connected to the axis 111 via a clutch 31, and, secondly, a second chamber 102 having a second axis 112 of compression, independent of the first axis 111, adapted to be driven by an electric motor 20.
- the axis 111 of the first chamber 101 of compression is driven by ie engine, the pulley 30 being coupled to the shaft 111 by the clutch 31.
- the refrigerant then flows through Îa first chamber 101 whose cubic capacity, of the order of 100 cm 3 , is chosen so as to allow the hybrid compressor 10 to ensure an optimum level of comfort inside the cabin of the vehicle, whatever the outside temperature, the temperature, and the degree of relative humidity.
- the air conditioning compressor 10 is no longer driven by the vehicle's heat engine and that, therefore, the air conditioning system stops operating and can no longer guarantee the maintenance of the temperature. of comfort inside the cabin. This is the case in particular during shutdown phases of the engine determined by an automatic shutdown and restart system of the engine capable of implementing its "Stop and Start" function for vehicles equipped with this function.
- the circulation of refrigerant fluid is switched from the first chamber 101 to the second chamber 102 by a valve device internal to the hybrid compressor 10, and then the electric motor 20 is started in a controlled manner. to drive the second compression axis 112 and keep the air conditioning circuit running during these stopping phases
- the cooling capacity to be provided by the electric motor 20 is relatively low.
- a cooling capacity of 6 kW is required to guarantee the comfort in the passenger compartment of a vehicle exposed to a high temperature of 25 to 45 ° C under a sunshine of 1000 Wm 2 and a relative humidity of 50 and 60 %.
- the cooling capacity to be supplied is between 1 kW and 3 kW depending on the segment of the vehicle.
- the displacement of the second compression chamber 102 can be limited, with respect to the displacement of the first chamber 101, to values close to 20 cm 3, for example.
- Se electric motor 20 is operated to drive the axis 112 of the second compression chamber 102 and thus ensure the maintenance of comfort in the passenger compartment during the stopping phase of the engine.
- the electric motor 20 must provide at startup a sufficient torque to overcome the resisting torque induced by refrigerant pressure rearrangements that occur in the air conditioning circuit at the time of shutdown. of the engine.
- the torque to be supplied by the electric motor 20 then becomes very important and requires powers greater than those strictly necessary to maintain the air conditioning.
- the invention proposes a method of managing the hybrid compressor 10 comprising the steps of detecting in advance a phase of interruption of driving of the first compression axis 11 1 by the heat engine, to switch the coolant from the first 101 to the second 102 compression chamber, and to start the electric motor 20 before the start of the interruption of driving the first axis 1 1 1 compression by the engine .
- the electric motor 20 is put into operation before the shutdown of the air conditioning circuit and therefore before any pressure rearrangements occur in the air conditioning circuit.
- the power of the electric motor 20 can therefore be dimensioned accordingly.
- FIG. 4 shows another circumstance in which the electric motor 20 can be put into operation in order to guarantee the continuity of the comfort temperature during a shutdown of the air conditioning circuit.
- This situation is that of an acceleration of the vehicle when it is best to meet the demand for acceleration by applying to the crankshaft a maximum torque obtained by recovering the resistant torque due to the drive of the compressor.
- the interruption of the drive of the first compression chamber 101 is not related to a stoppage of the engine, but to the decoupling of the drive pulley from the compression axis 111 of the chamber .
- the electric motor 20 is started as soon as the acceleration request is detected by usual detection means and before the heat engine is actually decoupled from the compression axis 111.
- FIG. 2 shows a hybrid compressor 10 'of the type comprising a variable-displacement compression chamber 100 whose axis 110 can be driven either by the electric motor 20 or by the crankshaft of the heat engine (no shown) of the vehicle via a belt and the pulley 30 adapted to be mechanically connected to the axis 110 via the clutch 31,
- this hybrid air-conditioning compressor architecture differs from the compressor of FIG. 1 in that it implements only one compression chamber and one axis. the only one that can be indifferently driven by the heat engine or the electric motor, instead of two separate compression chambers of independent axes.
- the pressure 110 of the compression chamber 100 is driven by the heat engine, the pulley 30 being coupled to the axis 110 by the clutch 31.
- the displacement of the compression chamber is then chosen in a higher range of values close to the maximum cubic capacity, of the order of 100 cm 3 for example.
- the hybrid compressor 10 ' is capable of ensuring an optimum level of comfort inside the passenger compartment of the vehicle, whatever the outside temperature, the sunshine and the degree of relative humidity.
- the air-conditioning compressor 10 is no longer driven by the vehicle's heat engine and that, therefore, the air conditioning system ceases to operate. operate and no longer ensures the maintenance of the comfort temperature inside the cabin. This is the case, as has been seen above, during the phases of stopping the engine determined by an automatic stop and start function of the type "Stop and Start", or during the phases of request for acceleration of the vehicle,
- the electric motor 20 is put into operation during the drive stopping phases of the compressor 10 'by the heat engine.
- the electric motor 20 then replaces the heat engine in its drive function of the compression chamber 100.
- the heat engine is preferably disengaged from the compression axis 110.
- the displacement of the compression chamber 100 can be reduced, relative to the nominal operating conditions, to values in a lower range of displacements close to the minimum cubic capacity of 20 cm 3, for example.
- the upper and lower ranges of displacements can be reduced simply to only the maximum and minimum displacements.
- the compression chamber 110 then switches binary between these two displacements according to whether the driving motor of the axis of the chamber is the heat engine or the electric motor.
- the electric power source may be a battery 40 or an additional unit with or without a storage capacitor.
- variable-displacement compression chamber 100 can be produced by a conventional vane compression chamber whose suction volume, corresponding to the displacement, is adjustable between the minimum value of 20 cm 3 , for example, and the maximum value of 100 cm 3 , for example, by varying the position of the suction port in the chamber.
- the hybrid compressor 10 of FIG. 1 it is possible to prevent the electric motor 20 from having to provide an increased torque of the resistive torque resulting from refrigerant pressure rearrangements at the shutdown of the air conditioning circuit by the implementation of a management method of the hybrid compressor 10 'comprising steps of detecting in advance a drive interruption phase of the compression axis 110 by the heat engine, to switch the displacement of the chamber 100 compression of the interval greater than the lower range of displacements, and start the electric motor 20 before the start of the interruption of drive of the axis 110 compression by the engine.
- the transition between the drive of the axis 110 of compression by the engine and the drive by the electric motor 20 is effected by uncoupling the pulley 30 from the compression shaft 110 by means of the clutch 31.
- the means for detecting a stoppage of the heat engine or an acceleration request are the same as those used for the compressor 10 of FIG. 1, as well as the control of the electric motor 20 by an anticipation signal of start-up.
