  • the "designated concentration” used in this article is a well-known concentration value of air components before and after normal breathing, such as the well-known percentages of N2 and C02 in the atmospheric volume of 78. 62 and 0.04, normal inhalation and The volume percentages of exhaled N2 and C02 are divided into 74. 09, 0.04, and 74. 5, 3.6. Therefore, when we test the purification efficiency of exhaled gas by the air purifier, the test gas N2 and C02 are " The "designated concentration” (percentage of volume) is 74. 5, 3.6.

Abstract

L'invention concerne un purificateur d'air et un procédé de détection associé. Ce purificateur d'air comprend : des plantes réalisant une photosynthèse et/ou une adsorption, des sources lumineuses placées au-dessus des feuilles de plantes, un contenant destiné à la culture des plantes, un réservoir d'eau et des tubes d'alimentation en eau permettant l'arrosage, des conduits d'air assurant le renouvellement de l'air, et des ventilateurs situés dans ces conduits d'air, un socle permettant l'installation et le raccordement des éléments de la machine, et un châssis de support relié à ce socle. Lorsque le ventilateur est actionné, une extrémité d'un conduit d'air situé à proximité de l'utilisateur forme une ouverture d'aspiration d'air à pression négative, qui aspire l'air expiré par l'utilisateur, et l'autre extrémité dudit conduit forme une ouverture de distribution d'air à pression positive permettant de souffler l'air en direction desdites plantes, et une extrémité d'un autre conduit d'air forme une ouverture, et l'autre extrémité du conduit, située à proximité de l'utilisateur forme une ouverture de distribution d'air à pression positive permettant de souffler l'air en direction de l'utilisateur, ladite ouverture de distribution d'air et ladite ouverture d'aspiration d'air étant disposées à l'opposé l'une de l'autre, de chaque côté des feuilles et/ou des racines des plantes.
