Definitions

  • the invention relates to the use of a ventilation device comprising a supply and an exhaust air device, a mixing chamber for outside air and recirculating air and a flap control for regulating the inside temperature of a shelter containing, in particular, movable internals that generate heat loss by means of outside air.
  • the company publication "MERO slot plate” discloses the use of a ventilation device for regulating the internal temperature of a room containing heat loss internals by means of outside air, the ventilation device comprising a supply and exhaust air device, a mixing chamber for outside air and recirculating air and a flap control.
  • a blower By means of a blower, "mixed air” is blown into the room to be air-conditioned from a mixing chamber in which supply air and exhaust air are mixed with one another via a raised floor.
  • the exhaust air to be removed from the room is sucked off by a blower and fed to an exhaust air chamber, which is connected to the mixing chamber on the one hand and to the environment on the other by means of controlled flaps.
  • the present invention has for its object to provide the use of a ventilation device in the manner specified in the introduction, which enables a temperature control in the interior of the shelter controlled by outside air to be realized with as little construction effort as possible, in which the fluctuations of Room temperature, based on the outside air temperature, are minimal.
  • All components of the ventilation unit are assigned to the same mounting wall; this also applies to the supply air duct, which in a first embodiment is laid on the floor of the shelter and in a second embodiment is suspended from the ceiling of the shelter and which is connected to the supply air device of the ventilation device on the mounting wall side.
  • the entire shelter interior results in an exhaust air flow directed against the mounting wall, that is to say towards the ventilation unit, and a sharp supply air flowing out at high speed from the induction slot outlets of the supply air duct in the manner of a high-speed air directed against the internals. Blowing flow.
  • the induction slot outlets enable the jet geometry of this blowing flow to be achieved by suitable adjustment of their air guide rollers, in such a way that the internals may have different configurations Heights, flowed sharply or through.
  • the heat given off by the internals is emitted to the blown air flow directly at the point of origin, which is either discharged as exhaust air to the outside via exhaust air openings in the part of the ventilation device which houses the exhaust air device, or is recirculated as recirculated air via a mixing chamber.
  • Two fans are preferably provided, which are connected on the suction side to the mixing chamber, into which an outside air duct connected to the surroundings via a suction opening also opens.
  • the invention is particularly advantageous for a shelter with an approximately rectangular outline, the mounting wall being formed by an end wall of the shelter, on the outside or inside of which the ventilation device is mounted.
  • the supply air ducts are connected to the pressure-side outlets of the two fans.
  • No undisturbed flow roller can form in the interior of the shelter, as is desired in conventional ventilation systems; rather, the exhaust air flows more or less in a cross-flow (horizontal) to the approximately vertical blowing jets of the supply air from the supply air duct, these blowing jets being directed specifically against the internals generating heat loss.
  • one or more exhaust air openings in the upper section of the device box are connected to at least one exhaust hood provided on the outside of the associated end wall of the shelter and that the outside air duct is connected to a downward-facing suction opening on the outside of the assigned end wall of the Shelters ends.
  • the temperature control is preferably carried out depending on the supply air temperature in such a way that a shutter flap which can be actuated by a servomotor is provided to control the proportion of exhaust air, recirculated air and outside air.
  • Venetian blind flaps are adjusted with the aid of the servomotors, preferably in such a way that the flap for the exhaust air follows the adjustment of the flap for the outside air in the same direction, while the flap for the circulating air is adjusted in the opposite direction to that of the outside air.
  • FIG. 1 to 3 of the drawing show the ventilation device in a first embodiment with a supply air duct 2 at the bottom.
  • the device box 1 is located on the inside of an end wall 4 of a shelter 5 with a rectangular plan.
  • a control unit 6 is also installed in the device box 1.
  • the device box 1 has 38 exhaust air openings 7 in the area of its upper corners and in its upper cover plate, which are connected to an exhaust air chamber 25.
  • the latter is connected via a blind 29 and an exhaust air opening 14 in the end wall 4 to an exhaust hood 26 arranged on the outside of the end wall 4.
  • the exhaust air chamber 25 is connected via a further blind 30 to a mixing chamber 22, in which a portion of the recirculated air from the exhaust air chamber 25 and the outside air are mixed.
  • This passes through an outside air duct 23, an outside air opening 15 in the end wall 4 and a blind 40 into the mixing chamber 22.
  • the outside air duct 23 is separated from the exhaust hood 26 placed thereon by a partition 41.
  • the mixing chamber 22 is connected to a suction chamber 36 of two fans 21 via a dust filter 37 and a silencer 24.
  • the fans 21 draw in either pure outside air, pure circulating air or a mixture thereof from the suction chamber 36.
  • the fans 21 are each connected on the pressure side via a flap 8 to a supply air chamber 20, to which supply air ducts 2 laid on both sides along the side walls of the shelter 5 are connected.
  • the supply air chamber 20 and supply air ducts 2 are arranged under an intermediate floor 16, on which the internals 33 generating waste heat or cabinets 9 containing such internals are constructed.
  • the supply air ducts 2 In its upper side formed by the intermediate floor 16, the supply air ducts 2 have so-called induction slot outlets, which are provided either in the form of rows 32 or of grids 3. Such rows 32 are arranged parallel to the longitudinal edges of the supply air duct 2. As is known per se, such induction slot outlets have adjustable Air deflecting rollers, which form nozzle-like blow-out slots between them, which enable a sharp and targeted flow against the internals 33 generating the heat loss. Such internals 33 are drawn in FIG. 3 above the left supply air duct 2 with dash-dotted lines; in practice, these are mostly switching devices for electrical systems, for example for switching telephone connections. The supply air emerging from the rows 32 of induction slot outlets is shown by arrows 34, which represent deliberate sharp blowing currents.
  • the supply air blown into the room passes as exhaust air according to arrows A through the exhaust air openings 7 into the exhaust air chamber 25, which is arranged in the upper region of the device box 1, and from there into the open air.
  • Both the blind 29 adjoining the exhaust air chamber 25 for the outflowing exhaust air A and the blind 40 adjoining the mixing chamber 22 for the inflowing outside air L and the blind 30 for the recirculating air U can be adjusted in both directions of rotation by means of switching motors (not shown) and in the entrance explained manner controlled.
