  • a self-contained air conditioning unit is ordinarily provided with an evaporator coil adjacent the front face thereof, room air being drawn into the unit through the evaporator, conditioned air being discharged through an outlet opening formed in the front face of the unit.
  • a suitable filter may be disposed adjacent the face of the evaporator for filtering the room air.
  • a front panel may be provided having an air inlet grille opposite the evaporator and a discharge grille over the air outlet opening to cover the internal components of the air conditioner and deflect the discharge air in the desired direction.
  • the air inlet and outlet grilles in the front panel while providing openings for passage of air into and out of the unit, also allow noise generated by the internal components of the unit to be passed into the area being conditioned.
  • This invention relates to an air conditioning unit including a casing having an interior compartment and an exterior compartment formed therein.
  • a refrigeration system including a compressor, a condenser, expansion means, and an evaporator forming a closed circuit is disposed within the casing, the compressor and condenser being located in the exterior compartment.
  • a horizontal partition is provided within the interior compartment, the evaporator being substantially vertically disposed between the bottom of the casing and the horizontal partition and spaced from the forward edges of the casing and the partition.
  • An air outlet is formed above the partition for discharging air into the area served by the unit, fan means being provided for drawing air from the area being conditioned through the evaporator into the casing and discharging theair from the outlet.
  • Hinge means are provided adjacent the lower front portion of the casing for pivotally mounting a first panel opposite the evaporator and spaced therefrom to provide a front closure for the lower portion of the casing and prevent transmission of sound into the area being conditioned.
  • a second panel disposed adjacent the top of the first panel is pivotally mounted on the first panel adjacent the air outlet to cover the outlet when the air conditioning unit is inoperative, the first and second panels being adapted to pivot about the lower front portion of the casing to expose the entire front of the casing for servicing the air conditioning unit.
  • FIG. I is a sectional view of a self-contained air conditioning unit
  • FIG. 2 is a view in elevation of the air conditioning unit of FIG. 1;
  • FIG. 3 is a sectional view taken along line III-III of FIG. 2.
  • a selfcontained air conditioning unit including a casing 2' comprised of a base pan 3, a top panel 5 and side panels 7.
  • the casing is divided into an interior compartment 9 pressor (not shown) a condenser 19, expansion means (not shown) and an evaporator 15 are located within the casing and connected to form a closed circuit, the condenser 19 being located within the exterior compartment 11,evaporator 15 being located within interior compartment 9.
  • a double ended fan motor 21 mounted on partition 13 is provided with an evaporator fan 23 and a condenser fan 25 for passage of air through evaporator 15 and condenser 19.
  • the interior compartment 9 is provided with a horizontal partition 27 and a vertical partition 29, partition 29 having a fan orifice 31 formed therein. Partition 29 cooperates with partition 13 and partition 27 cooperates with top panel 5 to form a L-shaped plenum within compartment 9 for discharge of conditioned air into the area being conditioned through opening 33 formed in the front of the casing.
  • An orifice partition 47 is provided in exterior chamber 11 for cooperation with fan 25 to draw ambient air from suitable openings 49 formed in side panels 7 for passage through condenser 19 for cooling the refrigerant therein.
  • the front face of the casing is provided with a first imperforate panel 50 spaced from and substantially parallel to the evaporator 15.
  • the panel 50 is provided with suitable hinges 52 for attachment to the side panels of the casing to allow pivotal movement of panel 50 relative to the front'ofthe casing.
  • a second imperforate panel 54 is pivotally secured to the top of panel 50 by suitable means such as hinges 56.
  • the door 54 is adapted to close the air discharge opening 33 when the unit is inoperative and to deflect the discharged air in the desired direction when the unit is in operation.
  • Suitable sound absorbent material such as fiberglass mats 57 on the inner surfaces of the L-shaped plenum, and foam rubber mats 58 on the inner surfaces of panels 50 and 54 is provided to absorb a portion of the sound energy generated by the unit.
  • imperforate panel 50 having sound absorbent material thereon, which is disposed opposite evaporator 15 serves to absorb a proportion of the sound energy produced by the unit and deflect a substantial portion of the sound energy not absorbed back toward the evaporator to minimize transmission of noise from the unit into the area being conditioned.
  • the absorbent material on panel 54 serves to dissipate a portion of the sound energy passing through opening 33. Since door 54 is also imperforate, a portion of the sound energy which is not dissipated by the sound absorbent material will be deflected through opening 33 back into the unit.
  • Spring clips 60 are suitably affixed to panel 50 by screws 61 for engagement with the side panels 7 to secure panel 50 adjacent the front face of the unit.
  • the side walls and top of self-contained air conditioning units are formed of sheet metal, which is secured to the base pan.
  • this sheet metal may be displaced slightly toward one side or the other of the unit due to mishandling or careless installation of the unit.
  • Clips 60 therefore, secure panel 50 adjacent the front face of the unit and also serve to align the side panels of the unit with the vertical edgesof panels 50 and 54.
  • the entire assembly may be pivoted away from the front of the unit for access to the interior of the casing for repair or servicing such as evaporator filter replacement or evaporator cleaning.
  • a refrigeration system including a compressor, a condenser, expansion means, and an evaporator connected to form a closed circuit disposed within said casing, said compressor and condenser being disposed in said exterior compartment;
  • a horizontal partition in said casing disposed within said interior compartment, said evaporator being substantially vertically disposed between the bottom of said casing and said horizontal partition and spaced from the forward edges of said casing and said partition;
  • fan means for drawing air from the area being conditioned through said evaporator for conditioning the air and for discharging the conditioned air from said air outlet;
  • first panel means pivotally mounted on said casing opposite said evaporator and spaced therefrom to provide a front closure for the lower portion of said casing to prevent transmission of sound into the area being conditioned;
  • first hinge means adjacent the lower front portion of said casing for pivotally securing said first panel means in position in said casing
  • second panel means disposed adjacent the top surface of said first panel means
  • first and second hinge means for pivotally mounting said second panel means on said first panel means adjacent said air outlet to close said outlet when the air conditioning unit is inoperative, said first and second panel means being adapted to pivot as a unit about the lower front portion of said casing to expose a substantial portion of the front of said casing for servicing.
  • An air conditioning unit according to claim 1 further including sound absorbent material mounted on the inner surfaces of said first and second panel means to attenuate noise generated by the air conditioning fi
  • An air conditioning unit according to claim 2 further including clip means mounted on said first panel means for engagement with the inner surfaces of the sides of said casing to resiliently secure said first panel member against the front of said casing and align the vertical walls of said casing with the vertical edges of said first panel means.
