Research on the Deodorization Efficiency of Indoor Cooking Odors by the Humidity Control Materials

We focused on the humidity control material as a means to control indoor cooking odors. For the purpose of understanding the deodorization efficiency of the building material, we measured the removal effect of ammonia by the small sample. And we measured cooking odors of the room (3640mm×7280mm×2500mm) where the humidity control material was used on the ceiling or the wall for 6 hours. The measurement items were odor concentration, odor quality, odor sensor vale, room temperature and humidity. The odor concentration and odor sensor value in the room with the humidity control material on the ceiling were low compared with the value of the room with the humidity control material on the wall. The deodorization efficiency was demanded by the reduction rate of odor concentration of cooking end in the room with the humidity control material on the ceiling for the condition without the range hood, and the value was 69%. The humidity control material was quite effective for the removal of remained odor in the room.
