Definitions

  • the invention relates to a device for heating and / or cooling air with an air-flow heat exchanger, which is arranged in a housing which forms a channel for the air flow, the housing at its end forming an air outlet in and / or in front of the Slats for guiding the emerging air flow are attached.
  • Air heaters which have fins in the air outlet in order to be able to direct the air jet emerging into the room in different directions as required.
  • it is also known from German Offenlegungsschrift 3638616 to attach pairs of fins in front of the air outlet in a V-shape, the side faces of each pair of fins being open to allow secondary air to enter. As a result, an early mixing and a deeper flushing of the room is achieved.
  • the object of the invention is to improve a device for heating and / or cooling air in such a way that with simple construction and variable room flushing, room air is mixed very early into the air flow.
  • At least one air inlet opening is arranged in the area between the air outlet and the heat exchanger in the housing side wall, and in that the duct has a cross-sectional constriction directly in front of the air inlet opening.
  • the device Due to the increased air speed in the area of the cross-sectional constriction, a negative pressure is generated behind the cross-sectional constriction, through which room air is sucked into the device through the air inlet opening (EN), so that the heated or cooled air flow behind the heat exchanger is mixed with room air very early.
  • EN air inlet opening
  • the device is of the simplest structural design and it is not necessary to design the lamellae guiding the air flow differently than usual.
  • the device for heating and / or cooling air has a housing 1 which forms an air duct 2, the cross section of which remains the same over the entire length L of the housing except for a cross-sectional constriction Q.
  • the air flows into the housing via an inlet 3 and is moved in the direction of arrow 5 by a fan 4.
  • the device or the housing 1 can also be connected to the outlet of an air channel, not shown, which supplies the device with air.
  • a heat exchanger 6 in the direction of flow 5, which is arranged approximately over the entire width of the channel 2 and through which the air flows.
  • the heat exchanger 6 heats or cools the air, thereby heating or cooling the air of a room.
  • the air outlet 7 is either surrounded by the end of the housing 1 or a frame 8, which can be part of the housing 1.
  • the frame 8 can also be a part which is fastened in front of the housing part and which contains the heat exchanger 6 and in particular the fan 4.
  • the housing 1 Between the air outlet 7 and in particular the fins 8 and the heat exchanger 6 are provided in the housing 1, or behind the housing area, which contains the heat exchanger, air inlet openings through the room air into the interior of the device and thus into the air flow that comes out of the heat exchanger exit. In the flow direction in front of the air inlet openings, there is a cross-sectional constriction Q, which constricts the air flow coming from the heat exchanger 6 and thus increases the flow speed.
  • the cross-sectional constriction Q is formed in the exemplary embodiment by a fixed baffle 10, which is fastened to the side of the housing wall 1 near the opening 9 and with an inclination of 30 to 60 degrees, in particular 45 degrees, into the interior of the housing and thus into the main air flow protrudes.
  • a rigid or movable guide plate 10 as a flat part, a hollow body or profile can also form the cross-sectional constriction at this point. It is also sufficient that the housing wall is bent inwards.
  • a movable air guide part 11 is rotatably (alternatively and / or displaceably) mounted in the housing in the area of the cross-sectional constriction Q near the opening 9 and can take the positions shown in FIGS. 3-5.
  • the air guide 11 is parallel to the baffle 10 at a distance from the baffle, so that between the air baffle 11 and baffle 10, a channel 12 is formed, the one Support current generates the intake of room air, especially at the beginning of the work of the device.
  • the air outlet speed changes depending on the position of the baffle.
  • the air guide part 11 extends the guide plate 10, so that the cross-sectional constriction Q is considerably enlarged and the vacuum, the suction power and the air speed are increased.
  • the air guide 11 is parallel to the main air flow, so that its effect is approximately canceled.
  • the air guide part 11 can be rotated into various intermediate positions as required or, in an exemplary embodiment not shown, can be shifted in order to change the air speed.
  • the housing has a rectangular cross section.
  • other cross-sectional shapes in particular a circular cross-sectional shape, are also possible.
  • the number of air inlet openings 9 can vary depending on the type and size of the openings and also on the intended use of the device.
  • two opposing air inlet openings are provided in two opposing walls of the housing.
  • an intermediate part between the air outlet or the frame 8 and the main housing part 1 can be attached.
  • the housing can also have an extension to form the air inlet openings.
