Experiment for synthetic evaluation of moisture buffering effect in a room

There are many research works for the moisture buffering effect of the building materials. However, there are few reports for the moisture buffering of the indoor contents such as wooden furniture, textiles and paper products except for the building materials in a room. In order to utilize the moisture buffering effect in the whole room, it is important to evaluate the synthetic moisture buffering including the indoor contents. In this paper, the experiment for moisture buffering of the contents in a room such as textiles and paper products is described. The objective of the experiment is to propose the evaluation method of the synthetic moisture buffering in a room. In the experiment, the test chamber (4.62 m3) installed the hygrothermal material on the interior surface is used. This chamber is located in the climate room to control the ambient conditions. The hygrothermal materials and various contents such as textile and papers are furnished in the test chamber. The response of indoor humidity change in humidifying in the test chamber is evaluated by two evaluation methods. These two methods are compared and discussed for the possibility of practical use as an evaluation method in the actual residential room.
