  • FIG. 3 is a cross section similar to FIG. 2 and showing a modified arrangement for turning the flaps about the axis.
  • the air conditioner 1 shown in partial cross section in FIG. 1 comprises a housing 10, the right or front wall of which is provided with a plurality of preferably louver-like slots 11 through which the upper portion 12 of the housing 10 communicates with the room in which the air conditioner is located.
  • Heat transfer means comprisingtubes 2, only one of which is indicated in dash-dot lines, are located in the upper portion of the housing and a cold or hot fluid medium is passed in a known manner, not forming part of the present invention, through the tubes 2. Air is passed in a manner as will be described later on about the tubes so that the air is cooled or heated and passes through the slots 11 into the room to be air conditioned.
  • the box-like housing 1 may be completely closed, or it may be open at the left or rear side and closed at this side by an outer wall 3 of the room to which the housing 10 may be connected in any convenient manner.
  • Blower means 4 are located in the lower portion of the housing 10 and this blower means extends transversely over the whole width of the housing and is driven by a motor not shown in the drawing. If the air conditioner comprises a plurality of units which may be arranged in any desired manner with respect to each other, then each unit may have its own blower means.
  • the blower means 4 comprises a casing 42' surrounding the rotatable part 4 of the blower means and having an inlet end 40 preferably flush with the front wall of the housing and closed by a grill or filter 41.
  • the outlet end of the casing 42 is integrally connected to a first air guide duct 42 which has a discharge end communicating with the upper housing portion.
  • the upper or discharge end of the first air guide duct 41 is arranged in the region of the inner end of a second air guide duct 5, the outer end of which passes through an opening in the wall 3 so as to communicate with the atmosphere outside the room in which the air conditioner 1 is located.
  • a grill or filter similar to that shown in 41 is located at the outer end of the second air guide duct 5.
  • a horizontal auxiliary wall 13 is arranged upwardly spaced from the second air guide duct and projects from the wall 3 to which it is connected in any convenient manner into the upper portion 12 of the housing.
  • Adjustable means comprising a pair of flaps 7 and 17, preferably of equal size, and including a preferably obtuse angle with each other are arranged turnable about a common axis 6 positioned in such a manner that during turning of the flaps about the aforementioned axis the free end edges of the flaps will move along a circle 27, indicated in dash-dotted lines, along which corresponding end edges a, b, c and d of the wall 13 and corresponding walls of thefirst and second air guide duct are located.
  • the ducts 5 and 42 are preferably of rectangular cross section and the obtuse angle between the two flaps 7 and 17 as well as the length of these flaps from the axis 6 are chosen in such a manner that the distance between the free end edges of the two flaps is equal to the distance of the free end edge of the auxiliary wall 13 from the free end of the left wall of the first air guide duct 42, respectively equal to the distance between the free end edge of the upper wall of the second duct 5 from the free end edge of the right or front wall of the first air guide duct 42.
  • the flaps 7 and 17 are fixedly connected to the shaft 6 for turning with the same about the shaft axis between at least three positions.
  • a first position shown in full lines in FIG. 1, the flap 7 engages with its free end edge the free end edge of the front wall or right wall of the first air guide duct 42 along a line indicated in projection at d, where as the free end edge of the flap 7 engages the upper wall of the second air guide duct 5 along a line indicated at b so that in this position air is sucked by the blower 4 from the room in which the air conditioner is located in the direction indicated by the arrows A through the grill 42 and passed through the second air guide duct 5 through the outer end of the latter to the atmosphere outside the room as indicated by the arrows A whereby air from the room is vented to the outside.
  • the flaps By turning the flaps in direction as indicated by the arrow B about the axis of the shaft 6, the flaps will be moved to a second position indicated in dash-dot lines in FIG. 1 in which the free end edge of the flap 7 engages the inner end edge of the wall 13, whereas the free end edge of the flap 17 engages the free end edge of the left or rear wall of the first air guide duct 42, whereby the second air guide duct 5 is closed so that air sucked in by the blower means 4 in the direction of the arrow C is passed in the direction of the arrows C into the upper part 12 of the air conditioner.
  • the blower means 4 when actuated, will suck air from the room in the direction as indicated by the arrows D and this air stream, indicated in dash-dot lines, will entrain air from the outside through the second air guide duct 5 in the direction of the arrows B into the upper part 12 of the housing 10 of the air conditioner so that air from the room together with outside air will be passed over the heat transfer means 2.
