Definitions

  • the present invention relates to a replacement air valve according to the preamble of claim 1.
  • the replacement air is preferably taken from outside air. It is also important for maintaining good indoor air quality air exchange takes place quickly enough.
  • the substitute air advantageously by a central Intake valve for replacement air is taken.
  • a central Intake valve for replacement air is taken.
  • This The disadvantage of this method is that the supply of replacement air to several Clear plumbing presupposes what increases construction costs and in the planning phase, setting up space for the pipe binding in the Constructions.
  • This type of procedure is also used Basic repairs difficult to do if you have the building to be repaired subsequently want to equip with a mechanical ventilation system.
  • GB-2087069 there is also a Replacement air valve described, in which the air entering the building room is directed upwards with the control organs.
  • the valve is for assembly provided on the casement, the penetrating through the window The amount of light decreases.
  • the air duct shown in this document lies however perpendicular to the main plane of the window, the air duct being short and the sound absorption capacity is low.
  • the Finnish layout specification FI-96442 provides an outside air valve Control elements of the air flow and an air filter.
  • the valve is direct executed in the casement.
  • This solution has the disadvantage that especially in cold weather in the spaces between the windows Moisture condenses, which is due to the fact that the Cold air flowing in between the window panes cooling skeleton structures of the outside air valve.
  • FI-Auslegeschrift 96442 Construction by a more complicated construction than that in the title application demonstrated replacement air valve.

  • the valve described in U.S. Patent 4,050,364 includes one ducting made of sound absorbing material. If the valve is in the position in which its sound absorption capacity is as large as possible the air duct has up to six corners, some of them even very steep, whereby this channel has a very large resistance to the incoming air opposite forms.
  • the end result is that the flow with a fan needs to be reinforced, but this adds to the complexity of the above Valve construction increased even more and on the other hand, this makes it Arrange the power input for the fan and also the damping assuming the fan's own noise. Should with the said Valve construction effective sound damping can be achieved, it demands vertically a noticeably large space compared to the height of the air duct in this direction. Et al due to these factors, this can be seen in the US patent In practice, the replacement air valve shown is not as one within the installation frame slot valve to be installed. The valve is for assembly on the wall, in the frame of the window or in an existing one Ventilation opening provided.
