Definitions

  • the present invention is in the field of air conditioning loops cooperating with a ventilation system, heating and / or air conditioning of a motor vehicle. It relates to a storage device participating in such a loop, better known as a bottle or accumulator. It also relates to an air conditioning loop comprising such a storage device.
  • a motor vehicle is commonly equipped with a ventilation, heating and / or air conditioning system to regulate the aerothermal parameters of the air contained inside the passenger compartment of the vehicle.
  • a ventilation, heating and / or air conditioning system to regulate the aerothermal parameters of the air contained inside the passenger compartment of the vehicle.
  • Such an installation cooperates with an air conditioning loop to cool a stream of air prior to the delivery of the latter inside the passenger compartment.
  • Said loop comprises a plurality of elements or components inside which circulates successively, that is to say in series, a component, such as a subcritical fluid, especially HF01234YF which is mixed with a known lubricant, for example under the reference IS0100PAG or IS0200PAG.
  • the index 100 or 200 qualifies the grade and thus the viscosity of the lubricant and PAG means PolyAlkylene Glycol.
  • ISO 100 corresponds to a kinematic viscosity close to 100mm 2 / s or cSt at 40 ° C, measured according to the international ISO standard.
  • the component and lubricant mixture forms the refrigerant fluid circulating in the air conditioning loop.
  • the components are at least one compressor, a condenser, an expansion member, an evaporator and an accumulator or a bottle.
  • the function of the lubricant is to lubricate the internal parts of the compressor.
  • the refrigerant flows from the compressor to the condenser, then through a bottle when the loop is equipped (instead of an accumulator), then to the expansion element, then through the evaporator, then to an accumulator when the loop is equipped (instead of the bottle) to return to the compressor.
  • the compressor is intended to receive the refrigerant fluid in the gaseous state and to compress it to bring it to high pressure and high temperature.
  • the condenser is able to cool the compressed refrigerant fluid at a relatively constant pressure, yielding heat to its environment.
  • the expansion member is able to lower the pressure of the refrigerant leaving the condenser by bringing it to the liquid state.
  • the evaporator is itself able to bring the cooling fluid arriving in the liquid state from the expansion element, at relatively constant pressure, into the gaseous state by taking heat from a stream of air. which passes through the evaporator. The vaporized refrigerant is then sucked by the compressor.
  • the accumulator or the bottle provides a storage function of a circulating coolant charge depending on the conditions of use of the air conditioning loop.
  • the accumulator also provides a separation function between a gaseous phase and a liquid phase of the refrigerant at the outlet of the evaporator.
  • Such an accumulator is known from the document FR-A-1415421 and document EP-A-1967800 .
  • the accumulator In its generality, the accumulator consists of an enclosure delimiting an internal volume used in part as a refrigerant storage zone. Thus, the coolant in the liquid state is accumulated by gravity in the storage or accumulation zone.
  • the oil return rate for a fixed displacement compressor or a variable displacement compressor is generally of the order of 5%.
  • the miscibility of the HFO1234YF component and the oil 100PAG or 200PAG is variable depending on the coolant temperature.
  • the refrigerant reaches a high temperature, especially 40 ° C at the condenser outlet, which greatly lowers the lubricant-component miscibility level to below the oil return rate of the compressor.
  • the compressor may receive less oil than necessary for its proper operation which at least will reduce its life and maxima will cause an immediate breakage of the latter.
  • a solution to this problem is the use of another component such as a fluorinated compound known as R134a, however R134a has a very negative impact on the terrestrial greenhouse effect, which is not the case of the component HF01234YF.
  • the object of the present invention is therefore to solve the problem of miscibility mentioned above by simple means whose establishment in the heart of an air conditioning loop does not interfere with the thermal performance of said loop.
  • the subject of the invention is therefore a device for storing a refrigerant fluid able to circulate in an air-conditioning loop having the features of claim 1.
  • the means intended to cause turbulence takes the form of a pipe which channels the refrigerant fluid from an intake chamber to the storage area.
  • This tubing is in the form of a conduit that concentrates the coolant in a jet.
  • the tubing is directly connected to the inlet tube and takes a semi-cylindrical shape, the free end of said tubular facing the storage area.
  • the arc formed by the semi-cylindrical shape directs the jet to the storage area so as to force the jet of coolant to hit the upper layer of the fluid stored in the storage area.
  • the tubing is distinct from the inlet tube, said tubing is carried by a plate which divides the internal volume of the storage device in a sealed manner into an intake chamber and said storage area. Separate means that the tubing and the inlet tube are not directly connected to each other.

  • Another advantage lies in the possibility of using a refrigerant fluid in air conditioning loops, particularly for motor vehicles, a component with a small footprint on global warming.
  • Another significant advantage lies in the fact of mixing this component with a lubricant with proven characteristics and whose cost remains low.
  • the figure 1 illustrates the technical problem. It shows a two-dimensional graph in which the abscissa represents the percentage of lubricant in the refrigerant which changes from 0% on the left to 50% on the right. The ordinate of this graph represents the temperature of the coolant within the loop measured at the input of the storage device according to the invention.

  • the percentage of oil in the refrigerant is 10%, which is higher than the value of oil return rate commonly known for a fixed displacement compressor, for example, 5% . It is therefore understood that the refrigerant fluid carries enough oil to prevent damage to the compressor.
  • the amount of lubricant in the coolant drops below the oil return rate, which results in a deterioration of the internal parts of the compressor and a breakage of the latter.

It is thus clear that the free end 25 of the tubing 13 faces the storage area so as to force the refrigerant fluid to strike the surface of the refrigerant stored, and thus avoid a separation between component and lubricant.
