Definitions

  • the invention relates to a method, a system and device for enriching ventilation or air conditioning with fragrances.
  • a humidification device for air conditioning systems in which the air stream to be humidified is directed towards the liquid surface of a drip water collecting container and a nozzle spraying the humidification water into the air stream above the inclined air stream obliquely onto the water surface is directed.
  • This known moistening device has i.a. the aforementioned disadvantages of water spraying and is moreover primarily intended for moisturizing purposes and not for the introduction of fragrances.
  • US Pat. No. 3,599,841 describes a device for circulating air with simultaneous enrichment with a Fragrance in which a container holding the fragrance is coupled to a channel through which the circulating air flows using an inlet and outlet valve such that the circulating air is passed as a whole through the container holding the fragrance when the valves are open, while when the valves are closed, the flow channel for the circulating air is also interrupted by the double-seat valve for further fluid flow.
  • the disadvantage of this known device is, inter alia, that permanent ventilation or air conditioning is not permitted since the air flow is interrupted at intervals.
  • the invention is based on the object of equalizing the enrichment of ventilation or air-conditioning air with fragrances.
  • the method set out in claim 1 is proposed. It enables a completely uniform enrichment of the ventilation or air conditioning air during the entire desired period. This period is normally the same as the daily operating time of the ventilation or air conditioning system.
  • ventilation or air conditioning air means that it can be both fresh air and circulating air and mixtures of the two. If shut-off valves for a partial air flow to be conducted through the container can be opened and closed in time or throttled, the flow rate of the partial air flow enriched with fragrances can also be controlled. The concentration of the fragrances in ventilation or air conditioning air can thus be controlled in a simple manner (claim 3).
  • Another possibility of enriching with fragrances only during part-time periods is to provide within the container having the evaporation surfaces that the intake air flow or partial intake air flow optionally comes into or out of contact with the evaporation surfaces. This is due to movable ventilation control surfaces, such as slides, flaps and the like. Like. Possible if they can alternatively direct the air flow over the free evaporation surfaces or over a correspondingly dimensioned parallel-connected ventilation duct (claim 4).
  • Another alternative to enriching the ventilation or air conditioning air only in predetermined part-time periods consists in the container containing the evaporation surfaces containing fragrances only during these part-time periods (claim 5).
  • part-time periods with different fragrance notes in series. This is preferably done by using a plurality of containers according to the invention, in particular connected in parallel with respect to the air flow.
  • the containers having the evaporation surfaces are to be emptied and cleaned at predetermined intervals and to fill (claims 6 and 8).
  • the measure according to claim 7 is proposed.
  • the use of a spray device for the dilution liquid has proven to be particularly simple and effective both for mixing and for cleaning the container (claim 9).
  • a system according to the invention for enriching ventilation or air conditioning air with fragrances in which the ventilation or air conditioning air is conveyed into a distribution system by means of a blower, in particular by suction, solves the task on which the invention is based by the combination of features Claim 11.
  • a device suitable for enriching the ventilation and air conditioning air with fragrances solves the task by the combination of features according to claim 12.
  • FIG Drawing shows:
  • FIG. 1 shows a device for enriching ventilation or air conditioning air with fragrances in a side view (schematic);
  • FIG. 2 shows an end view of the container from the same device (view A according to FIG. 1);
  • FIG. 3 shows a view from above of the same device (view B according to FIGS. 1 and 2), but without details of the structures and attachments as well
  • Fig. 4 shows a system for enriching ventilation or air conditioning with fragrances - as a schematic sketch.
  • the device 10 for enriching ventilation or air conditioning with fragrances in different views has a container 11 which is bordered by end walls 12, 13, a cylindrical base pan 14 and a flat cover plate 15.
  • the elongated, transparent cover plate 15 has, in the area of its one narrow side, a plurality of elongated supply air openings 16 which are protected from above with a semicircular dust protection device 17 against the ingress of dust which settles down. Like. Are protected.
  • the supply air can enter the open end faces 18 of the dust protection device 17.
  • a circular exhaust air opening 19 which is the only one in the drawing, is provided, which can be connected to the suction line of a blower 22 (FIG. 4) via a pipe socket 20 and a pipe line 21.
  • the container 10 can be supplied with a dilution liquid, in particular water, via a centrally arranged opening 23.
  • a dilution liquid in particular water
  • an atomizing head 24 is used, which can generate a wide-ranging atomizing cone 25.
  • the dilution liquid can be injected in predetermined times and predetermined quantities by means of a solenoid valve 26.
  • the container 11 can be charged with fragrance or fragrance concentrate from a storage container 29.
  • the exact mixing ratio can be set by means of a pump 30, such as a magnetic metering pump.
  • a pump 30 such as a magnetic metering pump.
  • an emptying opening 31 is provided which can be opened and closed by means of a solenoid valve 32.
  • All time functions can be triggered via at least one time switch 33.
  • the timer 33 can e.g. B. be designed as a weekly timer and switch the various valves at the set time on all days on which the ventilation or air conditioning air is to be enriched with fragrance.
  • the fresh water supply is initially kept open for a predetermined period of time, so that part of the water requirement is injected into the container 11.
  • the metering pump 30 is then started for a likewise predetermined period of time. Finally, water is mixed in again until the desired amount of water (e.g. 12 liters
  • FIG. 4 The mode of operation of the system in operation is best seen in FIG. 4: at the beginning of a A section of the pipe duct 35 shown is a blower 22 which draws in ventilation or air conditioning air from an intake tract 36. This can flow through a known upstream unit 37, in which it is cleaned, moistened, tempered and / or treated in some other way.

  • the device 10 can also be equipped directly with a blower so that it can serve as a compact unit for the ventilation of individual rooms.
  • the device is preferably connected to a (possibly already existing) ventilation or air conditioning system, in particular in the manner shown in FIG. 4.
  • the device can also be connected to a plurality of storage containers 29 for different fragrances, so that different fragrance notes can be introduced into the ventilation or air conditioning air on different days or at different times on the same day.
