Description

  The present invention is effective in purifying the air in a collective building having a plurality of rooms facing a corridor, such as welfare facilities such as nursing homes, hospitals, school buildings, dormitories, etc., and removing odors and harmful chemical substances. The present invention relates to an air purification type collective building and a method for purifying an air of the collective building that can improve the living environment by performing the same.

  For example, in a welfare facility such as a nursing home, a hospital, a school building, etc., multiple rooms are lined up facing the corridor, and people are living, recuperating, learning, etc. in each room. Air pollution and living odor in the building will become a problem. Of course, the presence of this polluted air and living odor is not desirable as a living environment. There is also a problem that the odor is strongly felt and the image of the facility is lowered.

  In addition, most of the buildings with multiple floors have a structure in which halls on each floor communicate with each other via stairs, and the stairs passage becomes a flow path to raise polluted air and living odor from the lower floor to the upper floor. However, there is a problem that air pollution and living odor become stronger as you go upstairs.

  As for the ventilation method in the conventional collective building, the exhaust type for each room by the ventilation fan provided in each room is common, but even if ventilation is performed by the ventilation plan by calculation according to the building standard method, the strength of odor, Because there are many uncertain factors such as generation amount and duration, the actual situation is that ventilation is not enough and the facility is stagnant. Also, some residents may stop because of the operating noise of the ventilation fan. Furthermore, in the season when heating is required, there is a problem that the heating cost increases because the warm air in each room is exhausted by the ventilation fan and the temperature in the room decreases.
