The present invention relates to a method and an apparatus for regulating the ventilation of a building. The present invention relates to a method and an apparatus for regulating the ventilation of a building............................................ the ventilation in a building.

Fram till idag har ventilationsbranschen uppnatt en mycket komplicerad ventilationsteknik som visat sig undermalig och inte ens klarar den mest elementdra uppgiften, dys att forse en lokal med frisk och halsosam luft. Det är ofta sofistikerade flaktdrivna ventilationssystem som till ett Mgt pris t.o.m skapar flera problem an de fran borjan var avsedda att losa. To date, the ventilation industry has achieved a very complicated ventilation technology that has proven to be substandard and does not even handle the most elementary task, no matter to supply a room with fresh and healthy air. It is often sophisticated fleet-driven ventilation systems that at a high price even create several problems than those from the beginning were intended to solve.

Svenska patentet 385 731 avser en "franluftsbegransande anordning i sjalvdragssystem" och i beskrivningsinledningen till detta patent beskrivs problemen med "okontrollerade" sjalvdragssyitem. Kortfattat är sjalvdraget and& stort vid stor skillnad mellan uteluft och inneluft (vintertid) och alltfor litet vid i huvudsak samma temperatur ute och inne (sommartid). Vintertid lacker saledes alltfor mycket uppydrmd inneluft ut och skapar ett undertryck i huset som "drar in" kall och torr uteluft, vilket, forutom att ge stora energiforluster, aven leder till en ohgsosamt torr luft inornhus. Swedish patent 385 731 relates to an "exhaust air limiting device in self-contained systems" and in the description introduction to this patent the problems with "uncontrolled" self-contained systems are described. In short, the natural duck & is large with a large difference between outdoor air and indoor air (winter time) and too small at essentially the same temperature outside and inside (summer time). In winter, therefore, too much heated indoor air leaks out and creates a negative pressure in the house that "draws in" cold and dry outdoor air, which, in addition to causing large energy losses, also leads to an uncomfortably dry indoor air.

Andamalet med foreliggande uppfinning är att astadkomma ett forfarande och en anordning for reglering av ventilationen i en byggnad som bygger pa gamla sAvdragsprinciper, men som kompletterats tekniskt for att fa vind, temperatur och skorstensverkan att "samyerka" for uppnaende av en optimal, sjalvverkande evakuering av franluft vid alla vaderforhallanden. The object of the present invention is to provide a method and a device for regulating the ventilation in a building which is based on old deduction principles, but which has been technically supplemented in order to obtain wind, temperature and chimney effect to "co-operate" to achieve an optimal, self-acting evacuation of exhaust air at all weather conditions.

Detta uppnas genom att forfarandet och anordningen erhallit de i patentkraven angiyna kannetecknen. This is achieved in that the method and the device have obtained the pitches specified in the claims.

I ritningarna visar hanvisningsbeteckning 1 en fast huv. En vertikalt lagrad axe! 2 kan rotera en rorlig del 3600 sâ att den alltid staller in sig i vindriktningen. En horisontellt lagrad axe! 3 anvands for spjallbladet 5 medan en horisontell platta 4 finns anordnad i den rorliga delen av anordningen begransande en kanals utloppsoppning vid balckanten (lasidan). Over utloppsoppningen är fastad en horisontell, krokt platta 6 som verkar som regnskydd samtidigt som undertrycket i utloppsoppningen kan forstarkas till ca - 1,3 Pd. Undertrycket i utloppsoppningen skapas sAledes av att lufthastigheten olcar genom en bAgformad forflyttningsvag, varvid det statiska trycket sankes. En bimetallspiral 7 andrar spjallbladets 5 grundinstallningslage alit efter radande utomhustemperatur. PA spjallbladet 5 finns aven anordnad en turbulensbildare som vid en viss vinkelinstallning av spjallbladet 5 dels star luftstrommen och vasentligt minskar undertrycket av vinden (vid +5°C och kallare) och dels paverkas av en vindanblasning (vilket ev ytterligare kan forskjuta spjallbladet mot ett annu mer forslutande lage. En motvikt 9 är kopplad till axeln 3, varvid man genom dimensionering av bimetallens elasticitet kan gOra spjallbladets 5 rorelse olinjar. Sammanbunden med den krokta plattan 6 finns en vertikal vindflojel 10, vars funktion är att stalla in den rorliga delen efter vindriktningen sA att vinden kan "samlas upp" under den kriikta plattan 6 och ovanfor den fasta huvens 1 mynning. In the drawings, male reference numeral 1 shows a fixed hood. A vertically mounted ax! 2 can rotate a movable part 3600 so that it always settles in the wind direction. A horizontally mounted ax! 3 is used for the throttle blade 5 while a horizontal plate 4 is arranged in the movable part of the device defining a channel outlet opening at the beam edge (lasidan). A horizontal, crooked plate 6 is fixed above the outlet opening, which acts as a rain cover at the same time as the negative pressure in the outlet opening can be increased to approx. 1.3 Pd. The negative pressure in the outlet opening is thus created by the air velocity oscillating through an arcuate displacement wave, whereby the static pressure is reduced. A bimetallic spiral 7 changes the basic installation layer of the throttle blade 5 alit after radiating outdoor temperature. On the throttle blade 5 there is also arranged a turbulence generator which at a certain angular installation of the throttle blade 5 partly stops the air flow and substantially reduces the negative pressure of the wind (at + 5 ° C and colder) and partly is affected by a wind blow (which may further shift the throttle blade towards another A counterweight 9 is connected to the shaft 3, whereby by dimensioning the elasticity of the bimetallic one can make the movement lines of the throttle blade 5. Connected to the curved plate 6 is a vertical wind vane 10, the function of which is to adjust the movable part according to the wind direction. so that the wind can be "collected" under the cricket plate 6 and above the mouth of the fixed hood 1.
