In each of the intermediate positions of the mixed air damper 62 between the outside air position 63 and the circulating air position 65, the mixed air operation of the air conditioning device 20 is possible. In the mixed air mode, a mixture of room air and outside air that can be set in relation to the mixing air flap 62 is sucked in by the fan 29.
  • the mixed air flap 62 is adjustable by means of the outside of the housing 21 arranged actuator 35.
  • the actuator 35 is preferably formed electrically, but it is also any other actuator for adjusting the mixing damper 62 conceivable.
  • this is a radial fan. It has an inlet opening 66 assigned to the inlet 59, through which the air is sucked out of the suction duct 61 into the fan 29. The air sucked into the ventilator 29 is subsequently blown out radially through a substantially cylindrical outer wall 67 of the ventilator 29, this being the case in each of the aforementioned operating modes of the device 20.
  • the sucked by the fan 29 and accelerated in the radial direction air is directed in the direction of the baffles 45 to the adjacent to the fan 29 arranged heat exchangers 68.
  • the air conditioning device 20 has - as already shown above - three heat exchangers 68, each of which is associated with a heat exchanger 68 each have a baffle 45 and thus each one of three areas 82 of the U-shaped shaft 49.
  • the heat exchangers 68 are in each case arranged in the fan housing 57, in each case on the sides of the baffles 45 facing the fan housing interior.
  • the air to be moved by the fan 29 is suitably conditioned in the heat exchangers 68, ie heated or cooled depending on the application.
  • the air conditioned in this way passes through openings 69 respectively arranged in each guide plate 45 in the U-shaped shaft 49.
  • the conditioned air is then supplied to the bottom part 22 via the shaft 49, in order finally to be able to blow out the air through the outlet openings 42 or 44 ,
  • This air movement is assisted or effected in the direction of the bottom part 22 by baffles 70 extending obliquely downwardly.
  • the baffles 70 are arranged in the U-shaped shaft, in each case on the shaft-facing side of the respective baffle 45, namely above the respective opening 69th
  • adjusting organs for adjusting the respective air flows are arranged on the inside 48 of the bottom part, namely in this case flaps 72nd
  • the flaps 72 are each arranged in a fold 71 between the bottom wall 37 and one side wall 38 and pivotally mounted on the bottom part 22.
  • one flap 72 is associated with one blow-off opening 42 in the bottom wall 37 as well as one blow-off opening 44 in the side wall 38 at the same time.
  • each of the same side of the bottom part 22 and to a common shaft portion 82 of the U-shaped shaft 49 arranged exhaust openings 42 and 44 are each assigned to a common flap 72.
  • Each flap 72 is pivotally mounted about a pivot axis 75 within the bottom portion 22.
  • the flaps 72 are guided during the pivoting movement by means of retaining plates 92, of which each flap 72 are each associated with two retaining plates 92, on arcuately extending oblong holes 93. They are non-positive, in particular frictionally engaged releasably fixable, so that the flaps 72 can be firmly positioned in any intermediate position within its pivoting range.
  • the flaps 72 are manually adjustable. Furthermore, however, it is conceivable that the flaps 72 are each adjustable by means of an actuator. As a result, the flaps 72 could be adjusted automatically within the framework of a suitable control method.
  • Each flap 72 has a flat main part 94 and an angled to this front part 95th
  • this cold air 90 is in a in the Fig. 9 shown cooling position 73 of the flap 72 is blown parallel to the bottom wall 37 through the exhaust openings 44 in the side walls 38.
  • the cooled air conducted by the fan 29 and the heat exchangers 68 is supplied to substantially the exhaust ports 44 disposed in the sidewalls 38 of the bottom portion 22.
  • the angle obliquely upwardly extending front portion 95 of the flap 72 supports this Leitvorgang.
  • this hot air 91 will be in one in the Fig. 10 illustrated heating position 74 of the flap 72 of the corresponding, arranged in the bottom wall 37 exhaust opening 42 is supplied.
  • each flap 72 completely releases its associated blow-out opening 42 in the bottom wall 37.
  • the main part 94 of the flap 72 is pivoted together with the front part 95 thereof accordingly upwards.
  • each flap 72 in this heating position 74 at the same time completely closes off its outlet opening 44 assigned to it in the side wall 38.
  • the hot air 91 is supplied in the heating position 74 by means of the flap 72 substantially the exhaust opening 42 in the bottom wall 37. This guiding process is in turn supported by the angled front part 95.
  • the hot air 91 in the heating position 74 of the flap 72 can be discharged from the air conditioning device 20 substantially perpendicular to the false ceiling 76.
  • the flaps 72 occupy one of the intermediate positions described above, the air flows are distributed to the respective, associated with the respective flap 72 exhaust ports.
  • the device 20 still has a U-shaped collecting trough 86, which is arranged below the three heat exchangers 68. This lies on the side of the three heat exchangers 68 associated baffles 45.
  • the flap 56 of the fan housing 57 and a bottom plate 87 of the collecting tray 86 are flush in the closed state of the fan housing 57 and close the fan housing 57 together downwards.
  • the drip tray 86 In addition to the bottom plate 87, the drip tray 86 still has a peripheral, perpendicular to the bottom plate 87 extending shelf 88. This can drain on the heat exchangers 68 accumulating condensate in the drip tray 86 and collected there. Upon maintenance of the device 20, the sump 86 may be removed from the device 20 and emptied. Alternatively, the accumulating condensation water, in particular together with accumulating condensation water from the collecting tray 34, are derived by means of a suitable pump.
