Definitions

  • the present invention relates to a receiver drier, more particularly, the present invention relates to a receiver drier configured on a condenser for a vehicle Heating Ventilation and Air-conditioning unit.
  • Conventional air conditioning system for example for a vehicle cabin includes condenser, an evaporator, an expansion device, a compressor and a heater.
  • the compressor pumps refrigerant gas up to a high pressure and temperature. Thereafter, refrigerant gas enters the condenser, where refrigerant gas rejects heat energy to external ambient (through ambient air or a specific low temperature coolant circuit), is cooled, and condenses into liquid phase. Thereafter, the expansion valve regulates refrigerant liquid to flow at proper rate, reducing its pressure due its expansion, and finally, the cooled liquid refrigerant flows to the evaporator, where the cooled liquid refrigerant is evaporated, reducing its temperature.
  • the refrigerant extracts or absorbs heat energy from air inside an enclosure to be conditioned, specifically, the vehicle cabin in case of a vehicle air conditioning system and returns to the compressor, and the above cycle repeats.
  • the heat extracted from inside the vehicle cabin and rejected to outside vehicle cabin results in cooling of air inside the vehicle cabin.
  • the conventional air conditioning system configured with expansion valve is also configured with a receiver drier that is disposed in the high-pressure section of the air conditioning system, usually located between condenser and expansion valve in the air conditioning loop.
  • a conventional receiver drier 02 is generally configured on an outlet side of a condenser 04.
  • the conventional receiver drier 02 is mounted along the outlet side of the condenser 04.
  • the conventional receiver drier 02 is integrally formed along the outlet side of the condenser 04.
  • the conventional receiver drier 02 includes a tubular casing 01 in form of an airtight container of a tubular configuration with an inlet 02a and an outlet 02b.
  • the inlet 02a is for receiving liquid refrigerant from a condensing section 04a of the condenser 04 via a first section 08a of a tank 08.
  • the outlet 02b is for delivering the liquid refrigerant to a sub-cooling section 04b of the condenser 04 via a second section 08b of the tank 08.
  • the inlet 2a is so aligned to heat exchange tubes 06 corresponding to the condensing section 04a of the condenser 04 that refrigerant entering inside, passing through and egressing the heat exchange tubes 06 corresponding to the condensing section 04a of the condenser 04 enters inside the receiver drier 02 through the inlet 02a configured on the tubular casing 01 of the conventional receiver drier 02.
  • the conventional receiver drier 02 acts as a temporary storage for refrigerant (and oil) and receives a desiccant material to absorb moisture (water) that may have entered inside the air conditioning system.
  • the receiver drier 02 also includes a filter to trap debris that may have entered inside fluid lines of the air conditioner unit.
  • the receiver drier 02 prevents the moisture and/or debris from reaching critical elements of the air conditioner unit, particularly the compressor, thereby preventing any detrimental impact to performance or damage to the critical elements of the air conditioner unit.
  • the conventional receiver drier 02 includes a sealing element 03 received inside the tubular casing 01 to collect the condensed refrigerant. A periphery of the sealing element 03 interacts with an internal rib 02c configured along inside wall of the tubular casing 01 and the sealing element 03 rests over a plug body 05 engaging with a first extreme end of the tubular casing 01.
  • the condensed, filtered refrigerant collected above the sealing element 03 is transferred via a tubular element 07 to a section 02d defined between a bowl 09a received inside the tubular casing 01 and an end cap 09b engaging with other extreme end of the tubular casing 01.
  • the bowl 09a is in fluid communication with and supplies condensed refrigerant to the sub-cooling section 04b of the condenser 04 via the outlet 02b and the second section 08b of the tank 08.
  • the receiver drier includes a plurality of elements that are required to be assembled inside the tubular casing and such assembly of the elements is inconvenient considering the elements being connected are inside the tubular casing and are not visible from outside the tubular casing. Accordingly, assembly and dis-assembly of the receiver drier of the present invention is inconvenient. Also, such configuration fails to provide ease and flexibility in serviceability of the receiver drier. Particularly, the prior art receiver drier for a condenser with internal inverted flow architecture permits serviceability from bottom only if condenser is of certain specific configuration or condenser is having a certain number of passes.
  • the receiver drier involves more number of components, assembly steps and processes.
  • the elements configuring the receiver drier can first be assembled outside the tubular casing and then inserted inside the tubular casing.
  • the elements of the receiver drier may be subjected to deforming forces and twisting and may be damaged while being inserted inside the tubular casing.
  • a receiver drier that exhibits ease of assembly and dis-assembly of the elements there of, particularly, close tolerance elements thereof, by reducing the efforts and eliminating risk of damage during assembly and dis-assembly.

  • this indexation is only meant to differentiate and name elements which are similar but not identical. No idea of priority should be inferred from such indexation, as these terms may be switched without betraying the invention. Additionally, this indexation does not imply any order in mounting or use of the elements of the invention.

Also, with such configuration, only the disc 70 at the distal end 50b of the tubular element 50 contacts inside walls of the tubular casing 10, while the assembly is being inserted inside the tubular casing 10. More specifically, with such configuration, the plug body 20, the filter body 30, the tubular element 50, the desiccant material 80 can be connected or assembled outside the tubular casing 10 and the assembly can be freely inserted inside the tubular casing 10 with ease and without being subjected to any deforming forces, twisting and without being damaged. Particularly, with such configuration, the assembly of the components inside the tubular casing 10 is convenient.
  • the plug body 20 forms removable engagement with the second open end 10b at the operative top of the tubular casing 10 to provide serviceability from operative top of the receiver drier 100.
  • the disc 70 at the distal end 50b of the tubular element 50 is gripped by the portion 10e of the tubular casing 10 upstream from the end cap 60 in the fluid flow direction "A" and closing the first open end 10a.
  • the first aperture 10c configures fluid communication between a condensing section 120 of the condenser 200 and the remaining section 14 of the tubular casing 10.
  • the refrigerant condensed in the condensing section 120 of the condenser 200 is received in the remaining section 14 of the tubular casing 10 and collected above the at least one, second sealing element 40b.
  • the second aperture 10d formed on the first section 12 configures fluid communication between the first section 12 and a sub-cooling section 110 of the condenser 200.
  • the filtered, condensed refrigerant received inside the first section 12, through the tubular element 50 is transferred to the sub-cooling section 110 of the condenser 200.
  • the desiccant material 80 is received within the tubular casing 10 in an annular space between the tubular casing 10 and the tubular element 50.
  • the desiccant material 80 absorbs moisture from any uncondensed and filtered refrigerant that had passed through the filter body 30 of the receiver drier 100.
  • the desiccant material 80 is silica gel.
  • the present invention is not limited to any particular desiccant material 80 as long as the desiccant material exhibits 80 hygroscopic properties.
  • At least one of the filter body 30 and the plug body 20 is provided with at least one second sealing element 40b.
  • the at least one second sealing element 40b is either one of at least one O-ring 42b received in at least one groove 22 formed by at least a portion of the filter body 30 in conjunction with the plug body 20 as illustrated in FIG. 3 and FIG.4 .
  • the at least one second sealing element 40b includes a plurality of radially extending wings 44b as illustrated in FIG. 8 that interact with and form sealing with inside walls of the tubular casing 10.
  • the present invention is not limited to any particular configuration, number and placement of the at least one second sealing element 40b, as long as the at least one second sealing element 40b prevent incompressible fluid such as moisture/water from escaping from the receiver drier 100 and reaching and harming the critical elements of the air conditioning system such as for example compressor. More specifically, the the at least one second sealing element 40b is capable of configuring sealing between the tubular casing 10 and the filter-plug assembly formed by assembly between the filter body 30 and the plug body 20.
