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 forming an air outlet at its end, 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 fasten pairs of fins in front of the air outlet in a V-shape, the side end faces of each pair of fins being open to allow secondary air to enter. This results in an early mixing and a deeper flushing of the room.
  • 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 into the air flow very early.
  • the device Due to the increased air velocity 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, so that the heated or cooled air flow behind the heat exchanger is mixed with room air very early on. This leads to a change in the air jet temperature and to an increase in the air outlet speed and thus to an increased flushing of the room and a reduction in the thermals.
  • the device is of the simplest construction and it is not necessary to design the lamellae which conduct 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 of the housing except for a cross-sectional constriction.
  • the air flows through an inlet 3 in the housing and is moved by a fan 4 in the direction of arrow 5.
  • the device or the housing 1 can also be connected to the outlet of an air duct, not shown, which supplies the device with air.
  • 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, 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.
  • air inlet openings In the direction of flow in front of the air inlet openings there is a cross-sectional constriction which constricts the air flow coming from the heat exchanger 6 and thus increases the flow speed. Since the air inlet openings are located directly behind this cross-sectional constriction, the underpressure generated by the cross-sectional constriction leads to intake of room air through the air inlet openings 9, so that room air enters the main air flow through the openings 9 Device is mixed and emerges from the air outlet 7 in the mixed state.
  • the cross-sectional constriction is formed by a fixed guide plate 10, which is fastened to the side of the housing wall 1 near the opening 9 and projects into the interior of the housing and thus into the main air flow at an inclination of 30 to 60 degrees, in particular 45 degrees .
  • a rigid or movable guide plate 10 as a surface part, a hollow body or profile can also form the narrowing of the cross section at this point. It is also sufficient that the housing wall is bent inwards.
  • a movable air guiding part 11 is rotatably (alternatively and / or displaceably) mounted in the housing in the region of the cross-sectional constriction near the opening 9 and can take the position shown in FIG. 3.
  • the air guide 11 is parallel to the baffle 10 at a distance from the baffle, so that a channel 12 is formed between the air baffle 11 and baffle 10, which generates a support flow that sucking in room air, especially at the start of the work Device supported.
  • the air outlet speed changes depending on the position of the baffle.
  • the air guiding part 11 can be rotated into different positions as required or moved in an embodiment not shown 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.
