Definitions

  • the present invention relates to a room ventilation system according to claim 1 or 2.
  • Air pollution i.e. the anthropogenic pollution of the atmospheric air by solid, liquid or gaseous foreign substances, is constantly increasing, so that the known ventilation systems do not do justice to the special tasks that air pollution poses.
  • the invention shows a way to take these special tasks into account and to arrive at a room ventilation system which also allows a saving of thermal energy of up to 100%, which has been preferred in recent times.
  • the room ventilation system according to the invention can mostly do without heating units, etc., that is, without primary energy being required for air heating. This has the advantage that smaller heat generator and distribution systems are required, which leads to an investment and a noticeable capital saving.
  • the 1 has an exhaust air duct 1, to which a plurality of valves 2, 3, ..., which can be, for example, poppet valves, are connected, for example to ventilate a wet room.
  • the output of the exhaust air duct 1 is connected to the input of, for example, a speed-controlled exhaust air fan 5, the output of which is connected via an exhaust air duct 6 to a shut-off element 7, the air flap of which is actuated by a servomotor.
  • the exhaust air duct 6 has a branch 8, to which a ventilation duct 9 is connected, which leads to the inlet of a circulating air shut-off element 10, the outlet of which is connected via a ventilation duct 11 and a branch 12 to an air supply duct, which has a prechamber 15 with another Shut-off device 14 connects.
  • the air flaps of the shut-off devices 10 and 14 can also be operated with one servomotor each.
  • the shut-off devices 7, 10 and 14 are controlled by the room temperature in the building. Instead of a flap, these shut-off devices can have, for example, a flat slide valve and the like.
  • the output of the pre-chamber 15 is connected by means of duct sections via the series connection of a pre-filter 16, an electrostatic filter 17, an activated carbon filter 18 and optionally an air heater and / or air cooler 19 to the input of, for example, a speed-controlled supply air fan 20, the output of which is connected via a supply air duct 21 to an supply air inlet 22 is connected to the wall 23 or in the ceiling of the staircase 24 of a building, the supply air inlet being only a little below or possibly directly on the ceiling.
  • Other walls 25, 26 of the staircase 24 are also provided with inlets 27, 28, on each of which a muffler 29, 30 is mounted, in order to allow the air in the staircase to pass as quietly as possible up to the area immediately below the ceiling of various rooms in the building .
  • a fixed pipe connection from the supply air duct 21 to the inlets 27, 28 is also possible.
  • the fans 5 and 20 will cause an air flow from the wet rooms via the poppet valves 2, 3, ..., the fan 5, the shut-off device 10, the filter device 15 to 19, and the fan 20 to the upper area of the staircase 24 is generated.
  • This will be harmful Retain substances as well as smoke and dust particles, which contaminate the air due to atmospheric air pollution and space pollution, from filters 16, 17 and 18. If the building is often closed for a long time, the oxygen consumed by humans must be replaced.
  • the chamber 15 has a small valve or shut-off device 15 ', which can be controlled separately from the flaps of the shut-off devices 7, 10 and 14, the flaps of which can thus be controlled synchronously, so to speak, preferably for any air circulation between 0 and 100% and automatically based on the room and injection temperature. So if the shut-off devices 7 and 14 are closed for a long time, the pre-chamber 15 receives fresh air through the valve 15 '. Of course, pollutants can simultaneously get into the antechamber 15; however, these pollutants are retained in filters 16 to 18. Leakage losses can thus be compensated for by the valve 15 '.
  • the invention has gained the knowledge that the periodic short-term and / or partial opening of the organs 7 and 14, which is anyway necessary due to the temperature control, is completely sufficient to admit the required amount of oxygen.
  • the invention also achieves an excellent heat balance. Because, for example, the shut-off element 10 can be constantly open in winter and the shut-off elements 7 and 14 can be constantly closed, no heat is lost to the outside world. This advantage is also used in summer, because when cooling is required, i.e. when the outside temperature is higher than room temperature, only the circulating air and not the warm outside air is cooled got to. The cooling load is thus reduced by approx. 1/3, whereby this ventilation system is also suitable for natural night cooling.
  • the stairwell and the corridors are flushed through the air inlet 22. Since the warm air on the ceiling is used and less energy is required for the buoyancy, lower injection temperatures are possible.
  • the room temperature in well-insulated buildings can occasionally be too high, namely because there are hours of sunshine and because both people and appliances of all types give off heat.
  • the servomotors of the shut-off elements 7, 10 and 14 can be actuated via a control with a temperature sensor in order to emit warm and used air and to admit fresh air.
  • the invention shows that the provided temperature control means that the shut-off devices 7 and 14 must remain open for so long that the question of the oxygen supply - as explained further above - takes a back seat.
  • the room heating should expediently be shut off automatically in order to prevent an oscillation between heating and cooling.
  • the 2 consists of two room ventilation systems according to FIG. 1, each with an exhaust fan 31 or 41, three shut-off devices 32, 33, 34 or 42, 43, 44 and two filter devices 35 or 45.
  • the room ventilation systems each serve for ventilation a large room 36 or 46.
  • the exhaust air duct of the first room ventilation system in front of the shut-off device 32 is connected via a branch 37 and a connecting channel 38 and, if appropriate, via a further shut-off device 39 to a further branch 40 on the supply air duct of the second room ventilation system after the shut-off device 43.
  • shut-off device 39 If the shut-off device 39 is closed, the two room ventilation systems function independently of one another, as described with reference to FIG. 1.
  • the shut-off device 39 can be opened to lead warm air from the room 36 via the filter device 45 to the room 46.
  • the shut-off devices 32 and 43 are closed and the shut-off devices 42 and 33 are open.
  • 1 and 2 can also be switched on in two or more stages.
  • the filter devices according to FIGS. 1 and 2 can have an additional special filter for this purpose.
  • an activated carbon filter also protects against radon and / or formaldehyde if they are only released in small quantities from the soil or from the building materials.
  • the optional prefilter 16 can preferably be a high-quality suspended matter filter, in particular for radioactive suspended matter, bacteria and viruses.
  • the fans can each have a measuring device 47, 48, which is preferably a frequency converter for speed control or a differential pressure meter in multi-stage operation. Monitoring of the filter contamination can also be provided.
  • a pressure measuring probe 49 and, in the case of speed control, a volume can serve as additional measuring devices for the exhaust air fan current probe 50 upstream and the supply air fan, a temperature sensor 51 and a speed measuring probe 52 are connected downstream.
  • the air discharged via the shut-off element 7 can be let out, for example, into the room of the apparatus center, which is thus heated, whereby this heat can be recovered by means of a heat pump.
  • the cleaned air is blown in via a floor duct 22 ', optionally via a parapet or blow-out column, and the polluted air is drawn off on or through the ceiling.
  • the cleaned air is not mixed with the polluted air, so that the blowing flow does not have to fight against natural buoyancy, which allows a higher temperature on the ceiling without further ado.
  • the carbonated air lying on the floor is greatly diluted by this blowing system and thereby takes a back seat.
  • the elements 15, 16, 17, 18 and 19 (FIG. 1) or at least a part thereof can be between the circulation shut-off device 10 and the branch 12 instead of between this branch 12 and the fan 20, as in FIG 1 may be arranged.
  • the volume flow can thus be reduced by up to 50%, which allows the use of smaller devices and thus a price reduction.
  • a heat exchanger can be provided in order to heat the temperature of the air of the supply air duct with the excess heat of the air of the exhaust air duct.
  • a heat exchanger can be provided anywhere in the circuit of the room ventilation system, in such a way that both the warmer exhaust air and the cooler supply air flow through the heat exchanger.
  • Such a heat exchanger is preferably used directly at the entrance of the room ventilation system, in such a way that it is connected to the outlet of the shut-off device 7 (FIG. 1) and to the input of the shut-off device 14 (FIG. 1).
  • Such a heat exchanger allows a substantial increase in the proportion of fresh air.
  • the exhaust air can be discharged into the room of the apparatus control center, in which a heat pump is provided, in order to utilize the excess heat of this room energetically with a pressure relief from the floor.
  • This heat exchanger can be constructed in such a way that it can be switched to an ineffective position in summer, for example.
  • the filter device 35 can also be arranged in series with the shut-off device 34 and / or the filter device 45 in series with the shut-off device 44.
  • a heat exchanger can also be inserted between the common inlet of the shut-off elements 33 and 43 and the common outlet of the shut-off elements 32 and 42.
