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 onto the liquid surface of a drip water collecting container and a nozzle spraying the dampening water into the air stream is directed obliquely towards the water surface above the inclined air stream.
  • This known moistening device has i.a. the aforementioned disadvantages of water spraying and is intended primarily for humidification purposes and not for the introduction of fragrances.
  • a method for air humidification is known with which the odorous substances are simultaneously removed from the ambient air to be humidified.
  • a container is provided that can only be partially filled with water.
  • One connection consists of a pipe opening just above the surface of the water, the other end of which opens into the ambient air.
  • the other connection consists of an opening in the container lid, which is assigned a fan for generating a flow through the container.
  • additives such as spring scent, chemical binders for odorants and the like.
  • This measure does not yet make the known device suitable for the uniform delivery of fragrances.
  • the mandatory impingement of the intake air on the water surface, which implements the step of air purification of odorous substances that is essential for this device, is in fact contrary to a uniform exposure of the air treated in this way to fragrances.
  • the gradual accumulation with odorous substances within the evaporation water namely changes the fragrance concentration released by the device over time.
  • this known device is also not intended or suitable for feeding the air flow treated in it into the air flow of a ventilation or air conditioning system (bypass circuit); At most, a treatment cleaning and humidification) of the total air flow of the ventilation or air conditioning system would be considered, since neither the air purification nor the air humidification in the partial flow process (bypass circuit) either would be sufficient in terms of cleaning and wetting effects.
  • the decisive disadvantage of this known device and procedure lies - as mentioned - in the fact that the desirable uniformity of the treatment of the treated air with fragrance by the impingement of an air jet on a part of the free water surface because of the resulting release of ingredients of the supply air to the water becomes impossible.
  • the object of the invention is to even out 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. However, it is also possible to enrich the ventilation or air conditioning air with fragrance only during predetermined part-time periods.
  • ventilation or air conditioning air means that it can be both fresh air and circulating air and mixtures of the two.
  • the partial air flow enriched with fragrances can also be controlled with regard to its flow rate.
  • the concentration of the fragrances in ventilation or air conditioning air can thus be controlled in a simple manner.
  • Another possibility of enriching with fragrances only during part-time periods is to provide within the container having the evaporation surfaces the possibility that the 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 sliders, flaps and the like. Like. Possible if they can alternatively direct the air flow over the free evaporation surfaces or over an appropriately dimensioned parallel duct.
  • the container having the evaporation surfaces contains fragrances only during these part-time periods.
  • the containers having the evaporation surfaces are emptied and cleaned at predetermined intervals and fill.
  • 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).
  • the concentration of the fragrance in the ventilation or air conditioning air can also be changed to a certain extent via a temperature control.
  • a system 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 object on which the invention is based by the combination of features according to claim 10.
  • the device 10 for enriching ventilation or air conditioning with fragrances in different views has a container 11 which is delimited by end walls 12, 13, a cylindrical floor pan 14 and a flat cover plate 15.
  • the elongated, transparent cover plate 15 has in the region of its one narrow side a plurality of elongated supply air openings 16, which from above with a semicircular dust protection device 17 against the ingress of dust settling down and. 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 21.
  • the container 10 can be charged 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 amounts.
  • 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.
  • 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 on all days on which the ventilation or air conditioning is to be enriched with fragrance, switch the various valves at the set time. Should the z. B. overnight out of operation and therefore preferably emptied device 10 are put into operation, the fresh water supply is first 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 of water with 10 cm 3 fragrance extract) is complete. Then, e.g. B. in the evening, the enrichment with fragrance is ended, the container 11 is automatically emptied and then sprayed with water for a predetermined time with the solenoid valve 32 open (cleaning phase).
  • the desired amount of water e.g. 12 liters of water with 10 cm 3 fragrance extract
  • FIG. 4 The mode of operation of the system in operation can best be 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 pipe duct 35 branches, for. B. in air distribution channels 38, the air outlet slots 39 at various locations, for. B. open in different rooms.
  • 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 several 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.
