碩士 === 國立臺灣大學 === 森林學研究所 === 90 === A fine interior decorative material is able to regulate the indoor temperature and relative humidity. It makes the changing ratio of indoor temperature and relative humidity reduce to the lowest, and reach to a steady region. Thus, it will create a healthy living environment, better living quality, less energy consumption and also lower the possibility that furniture and decorations deform due to the heat effects and humidity. The purpose of this study was to explore the conditioning effects of wood panels (used as interior decorating materials). An aluminum container with a controllable opening at one side was used in the study. The interior decorative materials with different types, thicknesses and A/V values (surface area of interior decoration materials attached to container/inside volume of container) were attached in the inner wall of aluminum container, which has a controllable opening. Then aluminum container was placed into a computer-controlled environmental chamber, which controlled hourly temperature and relative humidity in a living environment based on the data of average values form 1974 to 1990 in Taipei area. The aluminum container opened only at 1 p.m. ~ 5 p.m. (high temperature) or 5 a.m.~9 a.m. (high relative humidity). Then hourly temperature and humidity in the aluminum container was examined for the assessment of conditioning performances of interior decoration materials. Furthermore, the temperature and relative humidity conditioning performances of a wooden house and a RC house without decoration were analyzed both in summer and winter. The experimental results are summarized as follows: 1. After exposures in the humid climate conditions, according to assessment methods used in the study: (1) 3 solid woods, 11 wood-based materials and 1 composite material had better hygroscopic-conditioning performances. (2) The enough thickness of wood panel for better hygroscopic- conditioning performances was 0.6cm. (3) When the wood panel A/V value reached to 2.93 m-1, had better hygroscopic-conditioning performances. 2. After exposures in the hot climate conditions, according to assessment methods used in the study: (1) 2 solid woods, 5 wood-based materials, 1 composite material and 3 inorganic materials had better hygroscopic-conditioning performances. (2) The enough thickness of wood panel for better hygroscopic- conditioning performances was 0.3 cm. (3) When the wood panel A/V value reached to 2.93 m-1, had better hygroscopic-conditioning performances. 3. The changes of temperature and humidity of wooden house and RC house in summer and winter （1）The heat insulation in summer and heat preservation in winter of the wooden house was better than that of the RC house without interior decorative materials. The hygroscopic-conditioning performances of the wooden house were better than that of the RC house both in summer and in winter.
