  • a compressor in particular for a vehicle interior air conditioning system automobile, comprising an envelope defining a chamber high pressure containing a compression system of a refrigerant circulating in the air conditioning system, this compression system admitting the refrigerant at low pressure and driving it back at high pressure the high pressure chamber, an electric drive motor compression system and electronic means of command and control of the operation of the electric motor.
  • Compressors used to compress a refrigerant in a passenger compartment air conditioning system electrified motor vehicle are controlled by electronic power circuits.
  • the rotation speed of the compressor is controlled by an inverter which drives heat losses during operation. That is why it is necessary to cool these electronic circuits to keep them running and extend their life life.
  • a compressor of this type has several drawbacks. Its size is important due to the presence, at the exterior of the compressor, of a housing in which are housed electronic components. It is relatively complex to manufacture and assemble because you have to plan a modification of the suction line so that it ensures a necessary contact and heat exchange surface and sufficient.
  • the present invention specifically relates to a compressor of the type defined in the introduction which remedies these drawbacks.
  • This compressor has a low intake chamber pressure of the refrigerant integrated in the casing and separated from the high pressure chamber by a bulkhead separation, electronic means of control and control of the operation of the electric motor, placed in the inlet chamber, being cooled by the fluid refrigerant.
  • a compressor is produced with great compactness.
  • This compressor can be easily mounted in the vehicle because there is only one component to be fixed, and a single connection area for electrical and electronic circuits.
  • the noise level of gas pulsations on the compressor suction line, as well as the mechanical noises emitted by the compression pump and its valve are reduced by the presence of a volume buffer constituted by the intake chamber.
  • This compressor is reduced by integration of electronic control circuits compressor motor in a single enclosure.
  • the compressor has a separate chamber from electrical connection of the motor defined in the enclosure, this separate room communicating with the upper room pressure by a passage.
  • the intake chamber and the separate connection chamber electric motor are advantageously presented as open cavities towards the outside of the envelope and are closed by a blanking plate common to both bedrooms.
  • the closure plate is a terminal board fitted with all connection terminals necessary for the operation of the compressor. Terminals input and output for powering the electric motor and engine information output terminals (e.g. of the engine temperature) are located in a part of the terminal board which closes the separate connection chamber of the electric motor, and the other connection terminals are located in a part of the terminal block which closes the admission room.
  • Terminals input and output for powering the electric motor and engine information output terminals e.g. of the engine temperature
  • the other connection terminals are located in a part of the terminal block which closes the admission room.
  • the output terminals of the intake chamber and the motor input terminals in the separate room are fixed, permanent and isolated from the delivery of the terminal plate before mounting on the compressor casing.
  • the means electronic command and control of the operation of the compressor are arranged on a power module comprising a metallic cooling sole.
  • electronic means of command and control of the compressor operation are connected to the power, and these electronic means and the module power, except for the cooling soleplate, are coated in a plastic overmolding.
  • This plastic must be compatible with the fluid refrigerant and compressor lubricating oil.
  • She is preferably chosen from the family of thermoplastics polyester elastomers. We prefer to use a thermoplastic polyester elastomer known under the trademark HYTREL G 3548 from Dupont de Nemours.
  • the envelope is made in a first part containing the compression system of gas, the inlet chamber and the separate connection chamber electric, and a second part containing the motor electric, these two parts being assembled to each other according to a joint plan.
  • FIG. 1 shows a top view of a compressor 2 according to the present invention.
  • a compressor is intended to be part of an air conditioning system of the passenger compartment of a motor vehicle which so includes classic, a closed loop for circulation of a fluid refrigerant.
  • the refrigerant in the gas phase coming from of the evaporator (not shown) is allowed at low pressure in compressor 2 and discharged at high pressure into a condenser (not shown), which emerges in phase liquid. After expansion, the fluid returns to the evaporator in which it takes heat from the surrounding environment, and the cycle resumes.
  • compressor 2 includes an envelope 4 consisting of a first part 6 and a second part 8.
  • the envelope 4 is preferably made of cast aluminum.
  • Each of parts 6 and 8 has a flange 9 by which the two parts are joined together according to a joint plane, by example using screws (not shown).
  • the refrigerant compression system 10 is located in part 6. We will preferably use a compressor of the spiral type, also called “scroll” (Anglo-Saxon term). A compressor of the type can also be used. rolling piston.
  • the compression system 10 includes a low pressure intake chamber into which is admitted gas from the evaporator. He repressed this gas at high pressure in a high pressure chamber 15 defined at inside the enclosure 4.
  • the electric motor 12 of the compression system 10 is located in the second part 8. The speed of rotation of this motor can be adjusted by varying the frequency of the current and the electrical voltage that power it.
  • the gas from the evaporator enters the compressor 2 through an inlet 14 to be admitted into an intake chamber which will be described in more detail later.
  • Gas is admitted from the intake chamber directly into the compression system 10, then discharged in the high pressure chamber 15 which it crosses cooling the electric motor 12.
  • the gas leaves the high pressure chamber 15 through an outlet orifice 16 as shown schematically by arrow 17. It is then led to the condenser (not shown).
  • the intake chamber 24 appears as a cavity open towards the outside of part 6 of the envelope. It is separate from the bedroom high pressure 15 by a partition 26.
  • a communication orifice 28 is provided in the partition 26. This orifice allows gas to enter the compression system 10.
  • the gas from the evaporator enters through the intake orifice 14, as shown diagrammatically by the arrow 30, passes through the low pressure inlet chamber 24, then spring through the communication orifice 28 as shown schematically by arrow 32.
  • a second chamber 34 smaller than chamber 24, and is also presenting as a cavity open towards the outside of part 6 of the envelope, is arranged to allow the electrical connection of the motor.
  • a passage 36 passing through the envelope 4 puts the chamber 34 in communication direct with the engine located in the high pressure chamber 15. This passage runs along side 6 of the envelope 4 of motor 12 to lead behind the compression system in part 8 of this envelope.
  • Rooms 24 and 34 are closed by a common plate which at the same time constitutes the terminal block 20.
  • a joint 40 is provided to seal between the intake chambers 24 and 34 to seal the each of these rooms with the exterior.
  • Terminal plate 20 has been shown in front view on the Figure 3. It has six ears 44 allowing its fixing by screws 46 on the first part 6 of the envelope 4 of the compressor, thus compressing the seal 40.
