An absorption cell includes a first absorption layer formed of a first absorbent, and a second absorption layer formed of a second absorbent having a higher density than the first absorbent and coated on the surface of the first absorption layer so as to prevent generation of dust particles from the first absorption layer. The upper surface of the first absorption layer is coated with the second absorption layer formed of the high-density absorbent, thereby preventing generation of minute dust particles and thus preventing secondary contamination.

Absorption cell and manufacturing method thereof

A manufacturing method of an absorption cell includes preparing a first absorption layer formed of a mixture of a first absorbent and a second absorbent having a higher density than the first absorbent; coating the surface of the first absorption layer with a protective layer formed of a low-carbonizing point material and the second absorbent so as to prevent generation of dust particles from the first absorption layer; and removing the low-carbonizing point material from the protective layer so as to form a second absorption layer including a plurality of pore parts through which a fluid flows to the first absorption layer.

Absorption cell manufacturing method

A sterilizing method and apparatus in which neutral atoms and anions are coupled to produce a sterilizing substance which is, in turn, used to remove an object to be removed by sterilization. The sterilizing apparatus includes a cation generator and an anion generator, which are separate from each other. Also disclosed as an air cleaning method and apparatus using the sterilizing method and apparatus.

An air filter, an elevator having the same, and an air conditioning control method thereof purify the air inside the elevator to make the air safe and pleasant using a micro plasma ion generator (MPI). The elevator includes a cage which moves up and down in a vertical direction of a building and an air filter which purifies the air inside the cage. The air filter includes an ion generator which generates ions by a plasma discharge to discharge the ions into the cage, a dust sensor which detects a dust contamination level in the cage, and a controller which compares the dust contamination level detected by the dust sensor with a predetermined standard contamination level and operates the ion generator If the dust contamination level is equal to or greater than the predetermined standard contamination level.

Air filter, elevator having the same and air conditioning control method thereof

A ceramic electrode structure designed to have an enhanced construction, wherein an induction electrode has an area larger than that of a discharge electrode. A high square pulse voltage is applied to the enhanced ceramic electrode structure, thereby increasing an efficiency of ion generation and effectively restricting generation of ozone.
