Definitions

  • the technical sector of the present invention is that of air conditioning loops otherwise called loops or refrigeration circuits.
  • the invention relates to a unitary unit constituting such a loop.
  • An air conditioning loop is conventionally used on motor vehicles to generate a flow of hot air or a cold air flow sent into the passenger compartment of the vehicle.
  • This loop conventionally comprises a condenser, a bottle, an expansion member, an evaporator and a compressor traversed in this order by a refrigerant fluid.
  • the condenser is an exchanger crossed by an outside air flow while the evaporator is a heat exchanger through which the interior air flow flows, that is to say the flow of air sent into the passenger compartment of the motor vehicle. .
  • the refrigerant fluid that flows between an outlet of the compressor and an inlet of the expansion member is subjected to high pressure and high temperature while the refrigerant fluid circulating between the outlet of the expansion member and the inlet of the compressor is subjected to low pressure and low temperature.
  • Such an air conditioning loop can be improved by the addition of an internal heat exchanger whose function is to create a heat exchange between the refrigerant fluid subjected to high pressure / high temperature and the refrigerant fluid subjected to low pressure / low temperature .
  • the addition of this component improves the overall efficiency of the air conditioning loop.
  • FIGs 8 and 9 illustrate the technical differences between a battery and a bottle.
  • the structure of an accumulator is different from the structure of a bottle.
  • the figure 9 illustrates an accumulator which receives the refrigerant in the two-phase state (reference A). The latter separates in the liquid phase B and the gas phase C, the liquid phase B accumulating at the bottom and the gas phase C being in the upper part of the accumulator.
  • This accumulator comprises an outlet tube 40 bent whose inlet 41 is arranged to capture only the gas portion C of the refrigerant, accompanied by a determined amount of oil sucked by an oil hole 42 formed in the tube .
  • the object of the present invention is therefore to propose a new architecture of certain components of the air conditioning loop by combining in the same unitary unit and in a particular order the condenser, the internal heat exchanger and the bottle so as to gather these elements to pool the circulation of the refrigerant and thus gain compactness.
  • the invention therefore relates to a system comprising a condenser, an internal heat exchanger and a bottle adapted to be traversed by a refrigerant, said condenser comprising a coolant outlet orifice connected to the internal heat exchanger, said exchanger internal heat comprising a coolant passage connected to the innovative bottle in that the condenser, the internal heat exchanger and the bottle are adapted to be traversed in this order by the high pressure refrigerant and are unitarily collected.
  • the internal heat exchanger is directly downstream of the condenser and that the bottle is directly downstream of the internal heat exchanger in the direction of circulation of the refrigerant.
  • an expansion member for expanding the refrigerant fluid comprises a second channel connected to an output of said system, said detent member being part of the unitary unit.
  • the condenser has a beam capable of being traversed by an air flow, a first flank bordering said beam and a second flank bordering said beam and opposite to the first flank with respect to the beam, and in which the internal heat exchanger is secured to the first side while the bottle is secured to the second side. It is therefore understood that the beam is placed between the first and the second sidewall, and therefore between the internal heat exchanger and the bottle.
  • the internal heat exchanger is integral with the condenser while the expansion member is integral with the internal heat exchanger.
  • Solidarity means that the parts concerned are fixed to one another by removable or non-removable fastening means so that once assembled, there is no relative movement of a part by report to the other.
  • a first duct and a second duct run through the bundle, the first duct connects the outlet orifice of the condenser to the internal heat exchanger and the second duct connects the internal heat exchanger to the bottle.
  • the two ducts extend from the first side to the second side, said ducts being installed under the beam.
  • the system includes a second sidewall sidewall outlet and a high pressure inlet port, a low pressure outlet port, and a low pressure inlet port which are on the first sidewall of the beam.
  • the condenser has a beam capable of being traversed by an air flow, a first flank bordering said beam and a second flank bordering said beam and opposite to the first flank with respect to the beam, and in which the bottle is secured to the second sidewall and the internal heat exchanger extends from the first sidewall to the second sidewall in the extension of the beam.
  • the internal heat exchanger and the bottle are secured to the second sidewall.
  • the bottle is secured to the internal heat exchanger. In this case, the bottle is not in contact with the condenser.
  • the system comprises a high pressure inlet port on the first side of the beam and an outlet, a low pressure outlet orifice and a low pressure inlet port which are on the second side of the beam.
  • the high pressure inlet port is adapted to receive a refrigerant fluid subjected to high pressure and high temperature from the air conditioning loop, more particularly from a compressor.
  • the low-pressure outlet orifice is intended to supply the air conditioning loop, and more particularly the compressor, with the refrigerant fluid subjected to low pressure and low temperature, that is to say after having been relaxed by the relaxation.

  • the bottle comprises a desiccant and a filter.
  • the invention covers an air conditioning loop traversed by a refrigerant fluid and comprising a compressor, an expansion member, an evaporator and a system according to one of the characteristics set out above.
