Definitions
- the present invention relates to the production of electricity from an assembly comprising a heat engine and a power generation device for supplying one or more electric motors.
- the invention aims in particular to meet this need and thus relates to a set comprising:
- one or more electric motors notably an air-conditioning or vehicle refrigeration system
- the generator supplying the electric motor or motors directly, the supply voltage of the electric motor or motors being the output voltage of the generator.
- the electric motor or motors can each be used to drive a fan and to be condenser and / or evaporator motors.
- Each motor is according to the invention directly connected to the generator, without intermediate electronic device such as a voltage regulator or inverter, which reduces the cost of the assembly.
- the assembly according to the invention can thus be devoid of inverter. We do not go through a continuous bus to power the motor.
- the assembly may comprise a single condenser, or alternatively several condensers.
- the assembly may for example comprise two condensers.
- the assembly may comprise a single evaporator, or alternatively several evaporators.
- the assembly may comprise two evaporators.
- the motor (s) can be asynchronous or synchronous motors. They can be three-phase. They can be single or dual speed motors, which can maintain aeraulic performance close regardless of the speed of the engine. It is thus possible to limit the power absorbed in the event of an increase in the speed of the heat engine.
- the rotational speeds of the heat engine may for example be as follows: 1600 rpm and 2200 rpm.
- the motor or motors are preferably asynchronous motors, which are of simple construction and reliable use.
- the U / F ratio at the motor terminals is constant, which is possible thanks to the power supply by the generator. In the case where the speed of the engine would drop, then the voltage would drop but the ratio would remain constant. If the speed is too low, we can then change the coupling and switch to another polarity in the case where the motor is a two-speed motor.
- the motor or motors may be devoid of permanent magnets or alternatively may include permanent magnets.
- One or at least one of the motors may comprise a four-pole or six-pole rotor, which allows low-speed operation with low power consumption.
- the motor or motors may include a fan at each free end of their shaft.
- the engine can be a diesel engine.
- the heat engine and the electric motor (s) may belong to a refrigeration or air conditioning system of a vehicle.
- the engine may be different from the engine used to propel the vehicle.
- the generator is a synchronous machine.
- the engine can drive the generator shaft by a pulley-belt system.
- a pulley-belt drive allows the adjustment of the output frequency of the generator to the speed of the engine to allow the use of electric motors fans usable on the network directly without degradation of performance.
- the motor or motors can be designed to operate at 230V and 50 Hz for example, but they can also operate at 207 V and 45 Hz, the generator being driven for this purpose at 1350 revolutions per minute. If the thermal engine has a rotation speed of 1600 rpm with a ratio of 1.125 between the pulleys, then the 4-pole generator, for example, will be driven at a speed of 1800 rpm and deliver an output voltage to 60Hz as the network, thanks to its synchronous construction that induces no slippage.
- the generator can be rotated by the heat engine with a transmission ratio chosen so that the frequency delivered by the generator is the same as that of the external electrical network used to power the engine or engines when the vehicle is at the same time. 'stop.
- f ⁇ * ⁇ / 2 ⁇ with p the number of pairs of poles and N in rad / s.
- the generator can be permanent magnets.
- the rotor of the generator may comprise permanent magnets, being then for example a flux concentration rotor or buried magnets.
- the assembly may comprise a device for switching the power supply of the electric motor (s) making it possible to switch from a supply by the generator to a power supply via an electrical network.
- the motor or motors are connected directly to the network and the generator is then isolated.
- the rocker device can be configured to be able to engage when the vehicle stops, which avoids the pollution that can be induced by the operation of the engine at a standstill.
- This rocker device may comprise one or more switches for controlling the power supply of the electric motor or motors from the electrical network.
- the or each switch may comprise one or more electronic components.
- the or each switch can be made by any suitable means and for example using one or more electromechanical or semiconductor switches, for example with contactor (s), relay, thyristor (s), triac (s) , IGBT or bipolar transistor (s).
- the motor or motors can operate on an external electrical network such as a 230V and 60Hz network, or 460V and 60Hz, or alternatively 400V and 50Hz.
- the motor or motors may be multi-motors. voltage and multi-frequency. They can also operate with an electrical network at 50Hz.
- these motors can operate on power grids worldwide, which can be adapted regardless of the location of use and the characteristics of the local power grid.
- the assembly may further comprise a compressor driven mechanically by the engine.
- the training can be done by pulley-belt.
- the assembly may be devoid of a compressor driven by an electric motor, in normal operating mode of all at least.
- the assembly may also include a booster electric motor for driving the compressor when the latter is not or can not be driven by the engine.
- the drive can also be done by pulley-belt.
- This backup electric motor can be powered from the power grid.
- the assembly may comprise an electric compressor powered by the generator.
- the compressor may comprise an electric compressor motor and a pump driven by said motor, both arranged in a sealed enclosure.
- the assembly can comprise a hermetic compressor.
- the electric compressor can be powered directly by the generator.
- the supply voltage of the electric compressor may be the output voltage of the generator.
- the set may be devoid of batteries.
