  • Surface 46 connects opposite planar portions 42", 42 of surfaces 40, 41.
  • a plurality of nozzles 47 having openings 48 therein serve to discharge jets of air from the member.
  • the edges of the remaining planar portions 43', 43" together with the edges of the connecting surface 46 and the arcuate surface 45 form an inlet 49 for entrance of air into the hollow member from lower chamber 12.
  • the nozzle member includes two opposite side walls 40, 41 an arcuate end wall 45 connecting the side walls, and a top wall 46 connecting the side Walls, these walls being arranged to form an enclosure having an inlet 49 therein permitting air to fiow through the enclosure and to be discharged through nozzles 47 in the top wall 46.
  • Nozzles 47 are arranged in surface 46 in substantially parallel rows; preferably, nozzles in one row are substantially offset from nozzles in a second row.
  • a line drawn axially of a nozzle in one row forms an angle of substantially 35 with a line drawn axially of an ofiset nozzle in a second row. That is to say, a line drawn axially through each nozzle forms an angle of substantially 17 /z with a substantially perpendicular line drawn centrally of the nozzle member.
  • a flange 50 surrounds the inlet 49.
  • Flange 50 has a groove 51 therein which receives the Wall of the opening in wrap-per 21 to attach the nozzle member 23 to the plenum member 10.
  • any suitable adhesive may be employed to assist in holding the nozzle member 23 in place and to assure in sealing the opening in the Wrapper through which air enters the nozzle member.
  • Nozzle members 23 may be molded of suitable, flexible plastics such as polyethylene, polyvinyl chloride, etc. It is desirable that the member be flexible since such property greatly expedites cleaning of the nozzle and the removal of dirt particles collected therein.
  • triangular members 25 are attached to the end panels 22.
  • Coil 4 is attached to and is supported by the triangular members 25.
  • Coil 4 is placed below the nozzle members 23 and the plenum member and extends preferably at an angle to a line drawn perpendicularly of the unit 2.
  • a condensate pan 27 may be placed below the lowermost portion of coil 4. Any slight amount of condensate collected on coil 4 drips along the fins downwardly and falls into pan 27. It is intended that this unit operate with a dry coil, pan 27 being provided only to meet temporary conditions such as faulty start-up of the system.
  • base unit 3 and coil 4 may be furred in, if desired.
  • the air conditioning unit 2 is mounted on a wall of the room being treated.
  • the unit including the coil may be placed 4 to 12 inches, for example, from the fioor of the area being treated to permit such wall suspension.
  • Unit 3 is provided with hook members 29 adapted to hook over and be attached to a strip member (not shown) extending along the wall of the area being conditioned.
  • housing 5 is composed of a cover 30 (refer to Figure 1) having the outlet 7 therein, a removable panel 31, concealing the front of the unit, and end panels 32.
  • Housing 5 does not contain a base so that the bottom of unit 3 is open permitting secondary air from the area being conditioned to be drawn into the unit through the bottom thereof.
  • Cover 30 carries hooks (not shown) which permit the housing to be suspended from the wall strip referred to above.
  • a central station (not shown) supplies conditioned air to upper chamber 11 of plenum member 10. Air passes from chamber 11 through the damper arrangement 13 to chamber 12, static pressure in chamber 12 being regulated by the damper arrangement to maintain a desired static pressure therein. Jets of air are discharged from chamber 12 through nozzle members 23 at a predetermined velocity. Discharge of primary air through nozzle members 23 induces secondary air from the area being conditioned through inlet 6 and through coil 4 in heat exchange relation with heat exchange medium passing through the coil. The stream of secondary air after passage through coil 4 mixes with the streams of primary air being discharged from nozzle members 23, the mixture of primary and secondary air being discharged through outlet 7 into the area being conditioned.
  • the wrapper of plenum member 10 cooperates with the cover 30 and panel 31 to form a diffuser thus per-mitting more satisfactory mixing of the streams of primary and secondary air.

  • the nozzle construction may be easily and cheaply molded of plastics permitting the nozzle members to be simply attached to the plenum member and assuring a desired stream line flow of air to and through the openings of the nozzles.
  • Such flexible construction of the nozzle greatly enhances cleaning of the nozzles since dust and dirt particles collected therein may be easily removed.
  • a hollow air discharge member for use in an air conditioning unit including two opposite, spaced, planar wall portions, the contour of each wall portion being defined by two substantially straight edge portions extending at an angle to each other and an arcuate edge portion joining the substantially straight edge portions, the arcuate edge portions of the planar wall portions being joined by an arcuate wall portion extending from one arcuate edge portion to the other arcuate edge portion of the opposed planar wall portions, an upper wall portion connecting two opposite edge portions of the opposed planar wall portions having a plurality of openings therein through which jets of air may be discharged substantially upwardly from the member, nozzle members having their upwardly projecting sidewalls protruding from said upper wall portion defining the discharge openings, the remaining planar edge portions, the connecting wall portion and the arcuate wall portion forming an inlet in one side of the member adjacent the connecting wall portion and substantially opposite the arcuate wall portion for entrance of air into the member.
  • An air discharge member according to claim 2 in which nozzles in one row are substantially offset from nozzles in a second row.
  • An. air discharge member in which a line drawn axially of a nozzle in one row forms an angle of substantially 35 with a line drawn axially of an offset nozzle in a second row.
