Definitions
- the present invention relates to a method for determining the power of an electric motor of a hybrid compressor of 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 to automatically restart the engine after Its, 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 thermal engine to stop automatically, and the vehicle then 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 driving by the driver of the vehicle. clutch pedal, the 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 motor vehicle comprises a refrigerant compressor which is driven by the shaft of the crankshaft of the engine through a belt and a connected pulley mechanically to the axis of the compressor.
- the air conditioning circuit of the vehicle can only work if the engine drives the compressor. Therefore, during the phases of interruption of the drive of the compressor by the engine, including the stopping phases of 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.
- the refrigerant circulates in the air conditioning system through the mechanical compressor driven by the crankshaft of the engine, while the electric compressor is cut.
- the refrigerant fluid is directed towards the electric compressor, which is then driven by the electric motor.
- the passenger compartment is generally already conditioned in conditions of comfort, so that the cooling capacity to be provided by the electric motor to maintain these conditions for a time limited to a few tens of seconds is less, at least by a factor of 2 to 3, the power that must provide the engine. It is therefore possible to use a compression chamber of reduced displacement for the electric compressor.
- a hybrid compressor comprising a single variable displacement compression chamber having a compression axis adapted to be driven by the engine, under normal operating conditions of the air conditioning circuit, either by the electric motor during phases of interruption of the drive of the compressor by the heat engine, including the stopping phases of the engine determined by the function "Stop and Start".
- the displacement of its compression chamber is then provided to be able to vary in a range of variation having a greater range of displacements in which the compression chamber is driven by the heat engine, and a lower range of displacements in which the compression chamber is driven by the electric motor.
- an air conditioning circuit of a motor vehicle usually comprises a first so-called lowering phase of temperature (also known as the Anglo-Saxon "cool-down") that occurs when the vehicle is started after the latter has remained at a standstill for a sufficiently long time so that the temperature inside the cabin exceeds the comfort temperature sought by the occupants of the vehicle, around 18 ° C for example.
- the thermal power to be provided to reach the comfort temperature is relatively high, of the order of 6 kW when the vehicle has been exposed to a temperature of 25 to 45 ° C under a sunshine of 1000 Wm 2 and a relative humidity of 50 to 60%.
- the conditions for lowering the temperature are defined so that, when the comfort temperature is reached, the evaporator of the circuit is at a set temperature of between 4 and 8 ° C. , a temperature that best guarantees the elimination of a large part of the moisture contained in the air drawn inside the passenger compartment, as well as the limitation of the development of the bacteria responsible for the bad smells that can be felt in the cabin.
- a maximum temperature on the evaporator between 12 and 16 ° C remains admissible, because it is only beyond this temperature, said threshold of air conditioning discomfort, that the occupants of the vehicle perceive its inconveniences related to the moisture and bacteria.
- the first phase of descent in temperature follows a second phase of maintaining the comfort temperature, characterized by a thermal power to be provided substantially less, of the order of 3 kW, than that of about 6 kW which was necessary to bring the cabin at the comfort temperature.
- the heat engine In normal operation for driving the compressor, the heat engine which ensures the maintenance of the interior temperature to the comfort temperature.
- the electrical power to be supplied to the electric motor for a holding power of 3 kW is about 1500 W.
- an object of the invention is to propose a method for determining the power of an electric motor intended to drive a hybrid compressor of an air conditioning circuit of a motor vehicle with a combustion engine during phases of interruption of operation.
- the hybrid engine is driven by the heat engine, which nevertheless makes it possible to maintain a sufficient level of comfort in the cabin of the vehicle during the phases of interruption of the drive by the heat engine, even in the context of the vehicles of the segment "Micro Hybrid" where we only have a low voltage network to power the electric motor of the hybrid compressor.
- the invention provides that said maximum temperature is measured at the evaporator of the air conditioning circuit, and that said maximum temperature is the threshold of air conditioning discomfort.
- the reference time is defined as a duration compatible with the durations generally observed for the phases of interruption of re-entry by the heat engine. This reference time can be for example 35 s. It is thus understood that the power of the electric motor determined according to the method according to the invention can be made substantially lower than that which would be necessary to maintain the evaporator temperature at the set temperature of 4 to 8 ° C. has seen that it was of the order of 1500 W.
- the temperature measured on the evaporator can reach the threshold of air conditioning discomfort of 12 to 16 ° C at the end of the reference period of 35 s, it is then sufficient to use an electric motor with a lower power, from 500 to 800 W, which can be powered directly by the low-voltage network 12 V of the vehicle.
- the ratio of the power of the electric motor to the power required for the electric motor to maintain the temperature at said point of the air conditioning circuit equal to said temperature at the beginning of a phase of interruption of drive by the engine is between 0.2 and 0.8. More specifically, said ratio is between 0.3 and 0.55.
- said drive interruption is a shutdown of the engine.
- said shutdown of the engine is an automatic shutdown determined by an automatic shutdown and restart function of the engine of the vehicle ("Stop and Start").
- said drive interruption is a decoupling of the heat engine of the hybrid compressor determined by a request for acceleration of the vehicle.
- Figure 1 is a diagram of an air conditioning circuit comprising a hybrid compressor with two compression chambers.
- Figure 2 is a diagram of an air conditioning circuit comprising a hybrid compressor with a single compression chamber.
- FIG. 3 is a diagram showing the evolution of the evaporator temperature of a hybrid compressor air-conditioning circuit for different compressor operating phases.
- a conventional air conditioning circuit of a motor vehicle with a combustion engine comprising a compressor 10 of a refrigerant which may be an organic fluid, inorganic or eutectic.
- refrigerant which may be an organic fluid, inorganic or eutectic.
- Nonlimiting examples include carbon dioxide CO 2 supercritical refrigerants known as R134A, 1234yf or the 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 led to a pressure reducer 12 so that it is cooled before entering the evaporator 13 where heat exchange occurs 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 the heat engine, the pulley 30 being coupled to the shaft 111 by the clutch 31.
- the refrigerant then flows through the 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 outdoor temperature, the sunshine and the relative humidity.
- the air conditioning compressor 10 is no longer driven by the engine of the vehicle 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 the engine shutdown phases determined by an automatic shutdown and restart system of the engine capable of implementing the "Stop and Start" function of vehicles equipped with this function.
- the refrigerant circulation is switched from the first chamber 101 to its second chamber 102 by a valve device internal to the hybrid compressor 10, and the electric motor 20 is started from so as to drive the second compression axis 112 and maintain the air conditioning circuit in operation during these stopping phases.
- the cabin of the vehicle is in principle already brought to the comfort temperature, so that, since the duration of the stopping phases is generally limited a few tens of seconds, the cooling capacity to be provided by the electric motor 20 is relatively low.
- 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.
- FIG. 2 shows another type of hybrid compressor 10 'comprising a compression chamber 100 of variable displacement
- the axis 110 can be driven either by If electric motor 20, either by the crankshaft of the engine (not 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. it implements only a single compression chamber and a single axis that can be indifferently driven by the engine or the electric motor, instead of two separate compression chambers independent axes.
- 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 capacity, for example between 90 and 110 cm 3 .
- the hybrid compressor 10 ' is capable of providing an optimum level of comfort inside the vehicle cabin, irrespective of the outside temperature, sunshine and the level of relative humidity.
- the compressor 10 'of air conditioning n' is more driven by the engine of the vehicle.
- the air conditioning circuit then stops working and no longer guarantees the maintenance of the comfort temperature inside the passenger compartment.
- the electric motor 20 is put into operation in order to drive in turn the axis 110 of compression and ensure the continuity of air conditioning In other words, we can consider that the electric motor 20 is then substituted for the engine thermal in its driving function of the chamber 100 compression.
- the heat engine is preferably disengaged from S'axe 110 compression.
- the compression chamber 110 switches binaryally between these two displacements according to whether the driving motor of the shaft of the chamber is the heat engine or the electric motor.
- FIG. 3 shows three typical phases of the evolution of the temperature measured on the evaporator 13 of an air conditioning circuit comprising a hybrid compressor, whether it is the two-chamber compressor 10 of FIG. 10 'single chamber compressor of FIG.
- the first phase is the temperature-lowering phase (or "co-down") which generally takes place at the start of the vehicle when the latter has remained sufficiently long at standstill for the temperature of the evaporator 13 to be indoors.
- the cabin reaches relatively high T ext values, 25 to 45 ° C, above your comfort temperature, usually around 18oC.
- This temperature-lowering phase is carried out by means of the combustion engine of the vehicle by driving the first chamber 101 of the hybrid compressor 10 of FIG. 1 or the single chamber 100 of the hybrid compressor 10 'of FIG. 2, the displacement of the chamber 100 being chosen in the upper range of displacements.
- Setting the air-conditioning circuit is set so that the temperature in the passenger comfort can be achieved for the setpoint temperature T ⁇ ns of the values of the evaporator 13 between 4 and 8 ° C to remove the humidity of the air introduced into the passenger compartment and avoid the odors developed by certain bacteria.
- the maximum temperature T max admissible on the evaporator 13 is taken equal to the air conditioning comfort threshold of between 12 and 16 ° C., above which the odors produced by the bacteria become unpleasant to the occupants of the vehicle.
- the phase of descent in temperature requires the production by the heat engine of a thermal power of the order of 6 kW.
- the air conditioning circuit enters a second so-called maintenance phase of the comfort temperature.
- the invention proposes a method for determining a power of the electric motor 20 which would be compatible with a 12 V onboard network, but which would nevertheless guarantee the occupants of the vehicle a feeling of sufficient comfort during the generally short duration of the phases. considered here.
- a temperature of 12 to 16 ° C. is set a duration t ref reference for the phases of interruption of drive by the engine.
- This duration t ref can be determined by the average of the durations observed for the interruption phases, for example 35 s.
- the electrical power W elec of the electric motor 20 is defined so that at the end of the reference time W, the temperature measured on the evaporator 13 is at most equal to the maximum temperature T max .
- the evaporator temperature is equal to the temperature T max .
- the electric power W elec can be reduced to values for example between 500 and 800 W, compatible with the voltage of 12 V of the low-voltage on-board network of the vehicles of the targeted segment, while avoiding the emanation of bad odors that could occur at higher temperatures.
- the power determined by the method of the invention is in a ratio of 0.2 to 0.8, and preferably between 0.3 and 0.55,
