Definitions
- the invention relates to a device for managing the temperature of the air in an electric vehicle passenger compartment.
- HVAC Air conditioner
- plastic part generally comprising:
- a fan for operating the pulsed air system - A "cold" temperature exchanger for cooling the air from the air inlet device, usually called “evaporator”, if the exchanger is crossed by a refrigerant air conditioning,
- a "hot” heat exchanger generally called heater, temperature for heating the air generally from the cold evaporator exchanger. This operation is called “reheating” because it consists of heating air previously cooled or not.
- This hot exchanger is traversed by the cooling water of the engine. It allows to bring the calories produced by the engine and to use them for the heating of the vehicle,
- a temperature mixing flap that mixes air from the cold exchanger and air from the heat exchanger.
- the purpose of the temperature mixing is to ensure an ideal temperature of air blown to ensure thermal comfort in the passenger compartment of the car.
- the mixed air is then directed to the different outputs of the air conditioner, generally including the exits to the feet of the occupants, the exit to the defogger mouth of the windshield at the top of the board and the exits to the aerators allowing generally cooling occupants.
- These outputs are usually equipped with shutters that can best manage according to external conditions, the air distribution to the different outputs.
- an electric vehicle does not have an engine cooling circuit, based on a circulation of a coolant. Consequently, for such electric vehicles, the HVAC can not in particular ensure the component "hot exchanger" based on this circulation.
- a device for managing the air temperature in the passenger compartment of a vehicle according to the invention is particularly suitable for electric vehicles that do not have a cooling circuit based on a circulation of a cooling fluid.
- the subject of the invention is a device for managing the air temperature in an electric vehicle passenger compartment comprising a high-voltage network, an air-conditioning circuit, an equipment capable of cooling the air and equipment capable of heating the vehicle. before it is diffused into said passenger compartment.
- the main characteristic of a management device according to the invention is that the equipment capable of cooling the air and the equipment capable of heating the air are separated and are controlled independently of one another. In this way, each device can be driven independently regardless of the operating status of the other equipment, so as to obtain air in the passenger compartment at the desired temperature.
- the fact of being autonomous and being able to be driven independently of each other means that there is no interaction between the two equipment, in particular allowing hot air to be mixed with cold air to obtain a final air to the desired temperature.
- each equipment operates with an energy source of electrical origin, which is already present in an electric vehicle, to overcome the implementation of a specific energy source, specifically dedicated to these equipment.
- the equipment adapted to cool the air comprises an electric compressor powered by the high voltage network, the rotational speed of said compressor being controlled so as to adapt it to the thermal need in the passenger compartment at a given moment.
- the speed of rotation of the compressor is variable and can be adjusted to obtain the expected level of cold.
- the equipment capable of heating the air comprises a resistance electric heater.
- a radiator runs on electricity, which is already present in an electric vehicle.
- the resistor has a positive temperature coefficient.
- the equipment adapted to heat the air comprises a condenser instead of a heater if the air conditioning circuit is reversible, said equipment then being comparable to a heat pump.
- the equipment adapted to heat the air comprises a heater constituted by a brine / air heat exchanger, said device comprising an electrical resistance able to heat said water, a flow rate water is then created using a circulation pump.
- a device for managing the temperature according to the invention comprises a heater constituted by a brine / air heat exchanger, said device comprising a refrigerant / water exchanger in the form of a water condenser if the air conditioning circuit is reversible.
- a temperature management device comprises a purely electrical control source by means of a control module based on at least one type of transistor IGBT (English Insulated Gate Bipolar Transistor) .
- IGBT English Insulated Gate Bipolar Transistor
- a temperature management device comprises control sources of thermodynamic types.
- a temperature management device comprises two exchangers placed side by side, one being able to produce cold and the other being able to produce heat.
- a device for managing the air temperature in an electric vehicle passenger compartment has the advantage of being of a smaller size compared to the devices currently in use and involving a mixing flap and a chamber. mixing. It also has the advantage of being flexible in use, since the equipment capable of supplying cold and the equipment capable of supplying heat are controlled independently and can therefore contribute to producing a final air having a temperature variable.
- a management device according to the invention finally has the advantage of being better controlled due to the removal of the mixing flap, which required a certain placement accuracy.
- FIG. 1 is a schematic sectional view of a device for managing the air temperature in a vehicle interior according to the state of the art
- FIG. 2A is a schematic side view of a first mode of operation of a device according to the invention
- FIG. 2B is a diagrammatic side view of a second mode of operation of a device according to the invention.
- an air conditioning unit 1 or HVAC of a motor vehicle with a heat engine schematically comprises an inlet 2 of fresh air, a fan 11, an evaporator 3, a mixing flap 4 , a heater 5, a mixing chamber 6 and outlets 7, 8, of air at the desired temperature, for example to the feet of the occupants of the vehicle and / or to a windshield of said vehicle.
- the mixing flap 4 is placed upstream of the heater 5, and distributes the air to the mixing chamber 6 according to the needs of the moment.
- this flap 4 can adopt a first extreme position for which it allows the entire incident air from the evaporator 3 to pass through the heater 5, allowing the air found in the chamber of mixing 6 to be warmed up. It can also adopt a second extreme position for which it allows the entire incident air from the evaporator 3 to avoid the heater, allowing the air found in the mixing chamber 6 to be at the same temperature as that of the air from the evaporator 3.
- the flap 4 can finally be placed in at least one intermediate position located between these two extreme positions, to allow the passage of a first air flow 9 having passed through the heater 5 and a second direct air flow 10 avoiding said heater 5.
- the mixing chamber 6 receives the first and the second stream 7, 8 of air that mix before being diffused to the outlets 7, 8 of air.
- Such an air conditioning unit 1 is bulky because of the presence of the mixing flap 4 and the mixing chamber 6. It also requires precise control of the position of the mixing flap 4 which complicates its structure and operation.
- a device for managing the air temperature in an electric vehicle passenger compartment according to the invention makes it possible to control the temperature of the air injected into the passenger compartment, while avoiding the presence of the mixing flap 4 and the mixing chamber 6.
- This management device comprises a device 15 able to cool the air before it is distributed in the passenger compartment and equipment 16 adapted to heat the air before it is distributed in the passenger compartment.
- the peculiarity of this device is that said two devices 15, 16 are dissociated and are controlled independently of one another. In other words, the operating state of one of the two devices 15, 16 does not depend on the operating state of the other equipment 15, 16.
- These two devices 15, 16 are operated only to achieve target temperature of the air and are operated separately to achieve this purpose. Since in an electric vehicle, the air conditioning circuit can no longer benefit from the cooling circuit based on circulation of a cooling fluid to cool a heat engine, each equipment 15, 16 has its own energy source, preferably electrical and / or thermodynamic.
- the equipment 15 adapted to cool the air comprises an electric compressor powered by the high voltage network of the electric vehicle and whose rotation speed is controlled so as to adapt to the thermal need in the passenger compartment, a given moment.
- the speed of rotation of the compressor is variable and can be adjusted to obtain the expected level of cold.
- the equipment 16 adapted to heat the air comprises a resistance electric heater.
- a radiator runs on electricity, which is already present in an electric vehicle.
- the resistor has a positive temperature coefficient.
- the equipment 16 adapted to heat the air comprises a condenser instead of the heater, if the air conditioning circuit is reversible, said equipment then being comparable to a heat pump.
- the equipment 16 adapted to heat the air comprises a heater constituted by a brine / air heat exchanger, said equipment further comprising an electrical resistance adapted to heating said water, a flow of water being then created using a circulation pump.
- the equipment adapted to heat the air comprises a heater constituted by a brine / air heat exchanger, said equipment comprising a refrigerant / water exchanger in the form a water condenser if the air conditioning circuit is reversible.
- a management device comprises a purely electrical control source by means of a control module based on minus one IGBT type transistor.
- a management device comprises thermodynamic type control sources. Since the heating power and the cold generating power can be controlled independently and finely, it is no longer necessary to have mixing flaps 4 or mixing chambers 6 in the HVACs 6.
