Abstract

The mouthpiece of the ventilation system is fitted in the free end of a drum (3) with perforated walls. The drum is adjustable in its length within wide limits. The drum can be formed by rings movable telescopically in one another or by a bellows of flexible, limitedly air-permeable material. This permits stagelessly regulated inward blowing from a diffuse output to one directional and with high cooling effect.

Description

515 828 2 är var för sig ställbara för inriktning av olika luftströmmar fràn trummans nedre ände. En variant av detta visas i Fig. 4, där en enkel klaff 13 är svängbart lagrad vid trumändans ena kant och stor nog att täcka trumöppningen helt. Med klaffens hjälp kan luftmängden regleras och genom vridning av trumman kan luften riktas at önskat häll. 515 828 2 are individually adjustable for directing different air currents from the lower end of the drum. A variant of this is shown in Fig. 4, where a simple flap 13 is pivotally mounted at one edge of the drum end and large enough to cover the drum opening completely. With the help of the flap, the amount of air can be regulated and by turning the drum, the air can be directed to the desired pour.

Trumman kan också enligt Fig. 5 vara uppbyggd av teleskopiskt i varandra förskjutbara ringar 14,l5,l6,17 av perforerad plast eller plåt. Även till den utföringsformen passar ventilerna enligt Fig. 3 och 4.According to Fig. 5, the drum can also be built up of telescopically displaceable rings 14, 15, 16, 17 of perforated plastic or sheet metal. The valves according to Figs. 3 and 4 also fit that embodiment.

Verkningssättet är följande. Den perforerade trummans sidoväggar ger en diffus luftinströmning med làg hastighet fràn en stor yta och därför en dragfri ventilation, sàsom de övre pilarna i rit- ningsfigurerna visar. Om ventilen vid trummans nedre ände hàller stängd, kan mängden diffust inströmmande luft regleras med trum- längden. När riktad ventilation behövs, exempelvis för djurens kylning, öppnas ventilen i lämplig grad och àt det hàll som bäst svarar mot behovet. Den diffusa inströmningen fortsätter da men dess andel av ventilationen minskar, så att trumlängden kan in- riktas på att ge huvudsaklig ventilation direkt hos djuren vid trummans mynning.The mode of action is as follows. The side walls of the perforated drum provide a diffuse air flow at low speed from a large surface and therefore a draft-free ventilation, as the upper arrows in the drawing figures show. If the valve at the lower end of the drum is closed, the amount of diffuse inflowing air can be regulated by the length of the drum. When directed ventilation is needed, for example for cooling the animals, the valve is opened to the appropriate degree and in the direction that best meets the need. The diffuse inflow then continues but its proportion of ventilation decreases, so that the drum length can be focused on providing main ventilation directly in the animals at the mouth of the drum.

Förutom till djurstallar är anordningen värdefull för mànga andra lokaler. Ett exempel pà detta är verkstads- och kontorsmiljöer där maskiner och arbetsplatser har behov av selektiv friskluft- tillförsel.In addition to animal stables, the device is valuable for many other premises. An example of this is workshop and office environments where machines and workplaces need selective fresh air supply.
