Definitions

  • the invention relates to a ventilation device with a housing that has a suction opening for outside air and an outlet opening for the supply air in a room, and in which a fan, one or more filters, a heating device and a mixing device is provided, one with the inlet opening connected first inlet for the outside air and a second inlet for the supply of heated air and an air outlet.
  • Ventilation and air conditioning devices that have a housing with a suction opening, in which a suction grille is usually provided and through which outside air is sucked in by means of a fan, filtered by means of one or more filters, and the outside air in terms of its temperature and humidity with the aid of Heating and cooling devices as well as humidification and dehumidification devices is processed.
  • the conditioned air is discharged through an outlet opening to the room to be ventilated or air-conditioned.
  • a smooth-tube heat exchanger is provided in the entrance area, which is connected to a hot water circuit and heats the outside air entering the ventilation and ventilation device at low outside temperatures.
  • a smooth-tube heat exchanger causes additional costs for a second water circuit with appropriate control, increases the overall weight of the ventilation and ventilation unit significantly and also involves the risk of freezing if this is not prevented by the use of an equally expensive antifreeze.
  • a mixing chamber for a ventilation system of the type mentioned above which serves to make the heat of the circulating air of the room to be ventilated or conditioned usable by the outside air with the circulating air in the Mixing chamber proportionally mixed depending on the outside air temperature and as supply air to the air to be ventilated or air-conditioned Space is supplied.
  • exact control or regulation of the temperature inside the ventilation unit to protect against icing of individual units or moisture precipitation on the inside walls of the unit regardless of the required room temperature and humidity is not possible.
  • the object of the present invention is to provide a ventilation device of the type mentioned, the individual units of which are protected against icing and frost damage, which ensures cost-effective manufacture and operation and are associated with only a slight increase in the weight of the ventilation device, and allows precise control or regulation of the temperature inside the ventilation unit.
  • this object is achieved either by the characterizing feature of claim 1 or the characterizing feature of claim 2.
  • the solution according to the invention enables a cost-effective and effective protection of a ventilation unit against icing of the individual units or against frost formation as well as moisture precipitation inside the ventilation unit and ensures cost-effective operation.
  • Both configurations for protecting a ventilation unit against icing at low outside air temperatures are characterized by a simple construction with effective control or regulation of the temperature inside the ventilation unit depending on the outside air temperature.
  • a method for operating an air conditioning device mentioned above is characterized in that, below a predeterminable outside air temperature in the main flow direction, directly behind the suction opening, heated air is blown into the interior of the housing transversely to the main flow direction and mixed with the outside air in such a way that it is distributed over the cross section of the housing an approximately equal temperature level is reached behind the mixing zone.
  • the ventilation unit shown in longitudinal section in FIG. 1 has an essentially cuboid housing 1 which is provided with a suction opening 11 and an outlet opening 12.
  • a fan 2 is provided in the vicinity of the outlet opening 12 and generates a negative pressure in the housing 11 and an excess pressure at the outlet opening 12.
  • a coarse and / or fine filter 3 In the housing 1, a coarse and / or fine filter 3, a cooling device 4 with a condenser and a heating device 5 are provided, which is operated via a hydraulic circuit, which is not numbered in more detail.
  • the suction opening 11 has a suction grille or a suction hood or a Weather protection box 7, with the help of which the ingress of driving rain is prevented or reduced.
  • a connection and control device 10 is provided according to FIG. 3 for the electrical connection of the ventilation and air conditioning device and for the accommodation of corresponding control and regulation devices.
  • a bypass duct 8 branches off from the supply air duct adjoining the outlet opening 12, a bypass duct 8, through the air inlet 81 of which a partial flow Z 'of the supply air Z is branched off for the room to be air-conditioned and ventilated.
  • the bypass duct 8 opens into the underside of a mixing device 6, which is arranged directly behind the suction opening 11 or the suction grille 7.
  • the mixing device 6 is permeable to the outside air flow A running in the main flow direction, and serves to blow the part Z 'branched off from the supply air flow Z' transversely to the main flow direction into the housing 1 of the air conditioning device and to mix it with the outside air A.
  • one or more bypass flaps 64 are arranged, the position of which determines the proportion of the heated air supplied via the bypass duct 8.
  • the basic structure of the mixing device 6 is illustrated by a top view and a side view, respectively, and shows that perpendicular to the main flow direction, i.e. to the outside air flow A extending mixing tubes 65, which are connected to the second inlet side 62 and in which the heated, branched from the supply air Z air Z 'is guided.
  • This heated air is mixed over the length of the mixing tubes 65 of the outside air A drawn in perpendicularly thereto so that the air mixture has a uniform temperature over the entire cross section.
  • the ventilation unit shown in FIGS. 4 to 6 in side view, top view and end view essentially corresponds to the unit according to FIGS. 1 to 3, with the same reference numerals designating the same parts.
  • the heater 5 can be completely omitted in this device if such a heater is not required for ventilation and / or air conditioning of a room without the risk of icing or moisture penetration or frost damage inside of the ventilation unit.
  • an air injector 9 is provided, through whose air inlet opening 95 return air R from the room to be ventilated or air-conditioned by means of a Air injector 9 provided additional fan 91 is sucked in, filtered by an additional filter 93 and heated by an additional heating device 92 before it is fed via an injection channel 94 to the second inlet 62 of the mixing device 6.
  • the outside air drawn in can, if necessary, be heated independently of the supply air temperature given by the ventilation unit in such a way that icing or frost formation in the interior of the ventilation unit is avoided under all climatic conditions.
  • This device can therefore be used particularly advantageously in cases where a relatively low supply air temperature is desired, so that at low outside air temperatures the proportion of air mixed in via a bypass duct is too low to prevent the risk of icing.
  • FIGS. 7 to 9 Various exemplary embodiments of the mixing device 6 are shown in FIGS. 7 to 9 and are to be explained in more detail below.
  • FIG. 7 shows a cross section through a mixing device 6 with two rows next to one another and offset from one another by mixing tubes 65 which are surrounded by the outside air A drawn in by the first inlet side 61.
  • the heated air flowing through the mixing tubes 65 perpendicular to the plane of the drawing is entrained by the outside air A over the entire cross section of the mixing device 6 and exits the mixing tubes 65 via mixing tube outlet openings 66.
  • the Mixing tube outlet openings are arranged evenly distributed around the circumference of the mixing tubes 65 or are arranged only on the side which faces the outlet 63. Instead of mixing tube outlet openings 66, it is also possible to use mixing tubes 65 which are open on one side and which are closed in a semicircle toward the first inlet 61.
  • the longitudinal section shown in FIG. 8 through the mixing device 6 along the line B-B according to FIG. 7 illustrates the arrangement of the mixing tube outlet openings 66, which in the exemplary embodiment shown are only provided on the side facing the outlet 63.
  • the mixing tube outlet openings 66 have a different diameter or a different number distributed over the length of the mixing tubes 65, so that in the lower end adjacent to the second inlet 62, outlet openings 66 with a small diameter are provided, the diameter of which extends up to the closed end of the mixing tubes 65 increase continuously or in jumps, so that in the lower mixing tube area a smaller proportion of the heated air flows out or is entrained by the outside air drawn in transversely to the direction of flow, while in the upper region of the mixing tubes 65 a larger proportion of the heated air is drawn. This ensures that sufficiently heated air is also supplied to the endangered upper area and mixed with the cold outside air drawn in.
  • the same effect can be achieved with a different number of mixing tube outlet openings 66, with the same diameter of the outlet openings 66 Number of outlet openings to the upper closed end of the mixing tubes 65 increases.
  • the size of the outlet openings and / or the number of outlet openings can increase continuously or in steps from the lower end of the mixing tubes 65 adjacent to the second inlet 62 to the upper closed end of the mixing tubes 65.
  • FIGS. 9A to 9C show a schematic cross section through a mixing device 6 with a so-called mixing flap system, which has mixing flaps 67 articulated in pairs at articulation points 68, which are bent in a part-circle or parabolic shape, so that in the position shown in FIG. 9A they open the first inlet 61 close the mixing device 6 and thus prevent the entry of outside air, while in the position shown in FIG. 9B they prevent the supply of heated air supplied via the second inlet 62.
