  The present invention heats or cools the outside air taken into the building and supplies it indoors, purifying it by removing harmful chemical substances, pollen and other foreign substances during this period, and removing harmful factors such as sick house syndrome The present invention relates to an air purification type building that ensures a comfortable living environment and a method for purifying air in the building.

  Various foreign substances harmful to human beings, such as harmful chemical substances, pollen, dust, yellow sand, etc., float outside and fly on the wind. Therefore, in order to improve the living environment of a building, particularly a house, it is an important issue to remove these foreign substances in the atmosphere. It is also necessary to remove off-flavors and moisture in order to maintain the building in a comfortable environment. And since the charcoal which is a microporous material is effective in removing these extraneous matter, moisture, and a strange smell, the technique which arrange | positions charcoal under the floor of a building and purifies air is proposed.

  For example, the foundation structure part 2 is provided with a charcoal sill chamber 211 by a charcoal sillter floor 28 and charcoal sill wall surface 29 in which charcoal is spread over the entire floor. A floor side opening 14 through which the air is supplied through the charcoal sill chamber 211 via the fan 210 is provided. The roof structure part 4 is provided with a flow path of air from the living space part 1 and a house-cutting damper 45 for internal exhaust, and the air entered from the base structure part 2 is guided to the living space part 1 and discharged from the roof structure part 4 There is known a technology provided with a pressure adjusting means that includes an internal air flow path, an underfloor damper 27 and an interior room damper 45, and a fan 210, and maintains the air pressure of the living space 1 at a high level with respect to the outside. (Patent Document 1).
