左右されるものではない。Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, prior to the reduction work, the concentrations of indoor air pollutants such as formaldehyde and volatile organic compounds in the storage sections such as the ceiling, wall, floor and closet of each room are measured in advance. As a measurement method, a conventionally known quantitative analysis method such as an analysis method using chromotropic acid and an acetylacetone method is used. For example,
For a predetermined time (8 to 24 hours for home dwelling units, 24 hours for newly built buildings)
After sealing, the formaldehyde detector tube is placed at a measuring position with a standard height of 1.2 m, and the indoor air is sucked by a pump. Connect an extension hose in the storage space.
Usually, when a concentration equal to or higher than a predetermined value (0.2 ppm) is detected, the reduction work is performed, but the reduction work is not necessarily influenced by the measured values.

併せて行う。As a first step of the reduction work, the temperature of each room including a storage room such as a closet is raised to remove indoor air pollutants such as formaldehyde and volatile organic compounds contained in building materials and wall materials. The so-called bake-out work is performed forcibly volatilizing. The heating of each room is performed by heating the entire dwelling unit with the one-dimensional heat generator, heating the room unit with the two-dimensional heat generator, heating the small room with the three-dimensional heat generator, and heating the storage unit with the four-dimensional heat generator. At the same time.

スペースに向けて収納部の加熱を行うものである。[0011] The heating of the entire dwelling unit by the one-dimensional heat generation device is heating of the entire dwelling unit by a large heating device such as a jet heater, for example. It is installed and blows hot air into the room, while simultaneously sending outside air and exhausting room air. Further, the room-by-room heating by the two-dimensional heat generation device and the heating for the small room by the three-dimensional heat generation device mean that a heating device such as a fan heater or a stove is installed in a central portion of each room, and each room or small room is installed. Heat. Further, the heating of the storage unit by the four-dimensional heat generation device is to heat the storage unit by directing a small heater toward the storage space.

While spreading the heat evenly, while equalizing the temperature of the entire room,
The building materials and wall materials are heated to a temperature of about 40 ° C. for about 4 hours.

Simultaneously with the neutralization treatment, the aqueous solution is also subjected to a humidity control treatment in the room.

The remaining indoor air pollutants are adsorbed and removed by the adsorbent to reduce the final concentration to 0.08 ppm or less. As the adsorbent, generally, a porous structure is developed and has various pore structures, for example, an inorganic adsorbent such as silica gel, alumina gel, natural zeolite, synthetic zeolite, activated clay, flour earth, and the like. , Various activated carbon, bone charcoal, gas adsorbed carbon,
Use organic adsorbents such as molecular sieve carbon. At this time, an adsorption treatment operation using negative ions may be performed in combination. When the reduction work is completed, discharge other contaminants and residual contaminants and perform indoor heat cooling (radiation) treatment. Adsorption treatment of indoor odor and carbon dioxide generated by the reduction work is also performed as necessary.

During construction, the temperature and humidity are constantly monitored and controlled so that the temperature does not exceed 45 to 50 ° C., and the humidity does not cause cracks or the like in building materials. It is preferable to turn on an alarm lamp or to sound a buzzer when the regulation value is exceeded.
