Definitions

  • the invention relates to a ventilation system for ventilating a room with a first room zone and a second room zone, with an outside air unit, an exhaust air unit and with an air duct.
  • Ventilation devices for ventilating a room are known from the prior art as decentralized ventilation devices.
  • a decentralized ventilation unit is mounted directly in the room where ventilation is required.
  • the ventilation device is often arranged on the inside of an outer wall of a room.
  • CH 229 153 describes a ventilation system in which the air passes through a cavity before entering the room to be heated. The air is introduced into the cavity from the outside and then enters the lounge through appropriate air outlets. Of the Air inlet into the cavity is located in a first wall, a duct for air outflow is located in a second wall, which is opposite the first wall.
  • the invention is based on the object of creating a ventilation device that enables an improved, constant supply of fresh air, with the intention in particular to improve air hygiene with regard to health protection.
  • the air duct then leads from the outside air unit through the first room zone into the second room zone, with the outside air unit and the exhaust air unit passing through a first wall of the room and the supply air unit being located in the area of a second wall of the room. Consequently, the air is first conveyed from the outdoor air unit into the air duct.
  • the air duct has no openings in the area of the first room zone, so that no fresh air escapes from the air duct in the first room zone.
  • the air is blown into the room in the area of the second wall through the supply air unit. The air spreads out in the room and moves towards the first room zone.
  • the exhaust air is conveyed out of the room through the exhaust air unit in the first wall.
  • This cross ventilation causes fresh air to flow completely through the room by circulating the air from the outside air unit through the air duct to the second wall and from there back to the first wall.
  • the outdoor air unit and the exhaust air unit are located in an outer wall of a building, so that air can be brought into the room from the outside and then be conveyed outside again.
  • a room wall or a house wall is preferably provided as the wall.
  • the outside air unit and/or exhaust air unit are arranged in the area of a window.
  • the first wall is an exterior wall and the second wall is another wall of the room.
  • the second wall is an inner wall that is opposite to the outer wall.
  • the air duct is routed to the air supply unit on the ceiling or on a floor of the room.
  • a supply air grille is arranged in the supply air unit, which is suitable for scattering a flow of supply air.
  • the fresh air is divided into several partial flows and is therefore blown into the interior in a broadly diversified manner, and does not enter the room as a single air flow, which the user finds unpleasant.
  • the air is distributed well in the room by the various partial flows.
  • the outside air unit has at least one of the following components: an outside air filter, a coarse filter, a silencer and/or a UV filter.
  • the outdoor air grille prevents foreign bodies from entering the ventilation system from the outside.
  • the coarse filter filters coarse dirt particles out of the air.
  • the silencer causes a noise reduction of the ventilation system.
  • the incoming air is irradiated by an ultraviolet lamp through the UV filter, which kills germs that are in the air. Improved air hygiene is achieved through these components. Unfiltered air is a health hazard, especially in heavily polluted urban areas.
  • the use of the components roughly cleans the air in a first step, it being advantageous if as many as possible, preferably all, of these components are used.
  • the outside air unit is designed as a wall duct, which is preferably attached to the outside wall of an apartment.
  • This hole in the outer wall is preferably a core hole, in particular a round hole.
  • the bore is angular, in particular square or rectangular.
  • the arrangement of the outdoor air unit in a hole within the outer wall has the advantage that all components, i.e. the outer wall grille, the coarse filter, the silencer and the UV filter, can be accommodated in the hole.
  • the outdoor air unit is preferably preassembled as a module and is simply pushed into the core hole.
  • the outside air unit is arranged on an outside wall and is connected to the air duct by a hose leading through the outside wall.
  • a fan unit is arranged in the air duct.
  • the position of the fan unit is variable, i.e. it can be placed near the outside air unit, near the supply air unit or in a position between the outside air and the supply air unit.
  • the ventilation unit is preferably arranged in the area of the first spatial zone.
  • the fan unit preferably has at least one of the following components: a fine filter, a pollutant filter, a fan and/or a silencer.
  • the fine filter filters out fine dust particles, such as inhalable fine dust (PM10) and respirable fine dust (PM 2.5) from the air. This improves air hygiene, since fine dust is filtered out of the air, which is particularly important in heavily polluted urban centers.
  • the pollutant filter filters out further pollution from the air, in particular nitrogen oxides (NOX) and sulfur oxides (SOX).
  • NOX nitrogen oxides
  • SOX sulfur oxides
  • An activated carbon filter and/or a chemical filter is preferably used as the pollutant filter.
  • the fan is used to convey air.
  • the fan draws in outside air and transports it through the air duct to the supply air unit.
  • a constant volume flow fan is used as the fan, which calculates the air volume based on the speed and power consumption.
  • a remote control is provided with which the user can control the operation of the fan. According to one aspect of the invention, it is provided that the user only switches the fan on or off.
  • the degree of contamination of the fine filter is determined using the speed of the fan.
  • the speed of the fan decreases with increasing contamination of the filter. If the speed falls below a defined threshold value, this is recognized as contamination of the filter, which makes a filter change necessary.
  • the need to change the filter is preferably indicated to the user by means of a signal, preferably an optical or acoustic signal. The user is thus informed in good time that the dirty filter needs to be replaced.
  • the air volume of the fan can also be controlled by the user and can be controlled, for example, using a number of levels from “weak” to “strong”.
  • a further silencer is also provided, which further reduces the noise generated during operation of the ventilation system.
  • the fan unit is preferably configured as a preassembled module that is positioned in the air duct during installation.
  • the fan unit is made of EPS, into which the various components are plugged, and is surrounded by an injection molded housing.
  • the air duct has an insulating material in order to achieve a thermal separation between the fresh air flowing in and the room air in the room, so that no condensation occurs in the area of the supply air duct. Especially in areas where the outside air is at a higher temperature than the indoor air, especially in air-conditioned interiors, condensation can occur when warm outdoor air meets cooler indoor air, which in turn can lead to mold growth. Insulating the air duct prevents this condensation.
  • the insulation is shaped to form the air duct. This has the advantage that there is no need for an additional air duct, since the insulation itself forms the air duct. Furthermore, this has the advantage that the air duct can be installed quickly and easily by being on the Room ceiling or the room floor is arranged, for example, is glued.
  • the insulation consists of polystyrene with a smooth inner wall.
  • the air duct preferably has a simple shape, in particular it is designed as a flat duct, in particular as a round, oval or angular flat duct.
  • the first spatial zone preferably occupies approximately half of the room, the second spatial zone approximately the other half of the room, the first spatial zone being in the area of the outer wall of the room and the second spatial zone being in the area of the inner wall of a room.
  • An imaginary dividing line between the two room zones runs roughly in the middle of the room from the ceiling to the floor.
  • the first space zone is larger or smaller than the second space zone.
  • the first space zone occupies at least about one third of the space. This is necessary for the cross ventilation effect to be achieved.
  • the ventilation system is designed as an air supply system. To prevent condensation from occurring in the room, it is necessary for colder air to flow towards warmer air. If warmer air flowed in the direction of colder air, condensation would occur in the area where the two air flows meet.
  • the ventilation system is therefore preferably designed as an air supply system. This means that there is overpressure in the room. Due to this overpressure, the air inside the room, i.e. the colder air, flows in the direction of the warmer outside air, which prevents condensation.
  • the ventilation system is designed as an exhaust air system. The ventilation system in this case is preferably used where the outside air has a lower temperature than the inside air.
  • a Provide negative pressure in the room In order for the colder air to flow in the direction of the warmer air to avoid condensation, a Provide negative pressure in the room. This negative pressure causes the colder outside air to flow in the direction of the warmer inside air.
  • a further fan unit is provided in the exhaust air opening.
  • a pressure control is therefore preferably provided in which the two fans in the fan unit and in the exhaust air opening communicate with one another so that the fan in the exhaust air unit conveys a higher air volume than the fan in the fan unit.
  • both fans are preferably coupled to one another in such a way that a change in the target air volume on the fan of the fan unit has a direct effect on the air volume of the fan in the exhaust air opening.
  • the room 2 has a first room zone 22 and a second room zone 23, with an imaginary dividing line 24 running between the first room zone 22 and the second room zone 23.
  • the imaginary dividing line 24 between the first spatial zone 22 and the second spatial zone 23 runs approximately in the middle of the room 2, specifically from a ceiling 204 to a floor 203.
  • the first spatial zone 22 and the second spatial zone 23 are thus in about the same size, although a different size ratio is also possible.
  • Room 2 has a ceiling 204, a floor 203, a first wall 201 and a second wall 202.
  • An outside air opening 21 is provided in the area of the first wall 201 .
  • An outside air unit 11 is introduced into this outside air opening 21 , through which outside air 31 enters an air duct 12 .
  • the air duct 12 has an insulation 121 which is arranged on the room side.
  • a fan unit 13 is arranged in the air duct 21 and has, among other things, a fan with which outside air 31 is sucked into the air duct 12 as duct air 32 .
  • the duct air 32 enters the room as supply air 33 in the area of a supply air unit 14 .
  • an exhaust air opening 25 is provided in the area of the first wall 201, in which an exhaust air unit 15 is arranged.
  • the supply air 33 is distributed in the room 2, an exhaust air 34 flows through the exhaust air unit 15 and is discharged as exhaust air 35 to the outside.
  • the outside air unit 11 has an outside air grille 111 , a coarse filter 112 , a silencer 113 and a UV filter 114 . These components ensure that pollutants are filtered out of the incoming air.
  • the fan unit 13 has a fine filter 131 , a pollutant filter 132 , a fan 133 and a silencer 134 .
  • the fan 131 causes outside air to be sucked in and conveyed into the room.
  • the silencer 134 reduces the noise of the ventilation system.
  • the fine filter 131 and the pollutant filter 132 filter other harmful particles from the air.
  • FIG. 4 a schematic view of a supply air unit 14 is shown.
  • the draft unit 14 has a supply air grille 141 .
  • the supply air grille 141 has slats 142 which divide the air flow into several partial air flows and thereby spread the air flow widely.
