  • Other en The study used different coniferous and broadleaf species, from domestic wood in Taiwan, as the specimens to determine the effect of various species on thermal conductivity (λ) at different densities. The environment changes of relative humidity (RH) in the moisture content (MC), and the influence of temperature variation on the λ of various species were investigated. The air–dried density of various species was in the range of 0.30 to 0.91 g/cm3, and the λ ranges were from 0.1367 to 0.2270 W/mK. The higher the density, the faster the λ. In other words, the lower the density with a slower λ because of porosity of wood. The MC increased from 4.0 to 20.0%, the λ increased from 0.1090 to 0.1900 W/mK. The λ of wood increased with the increase of MC. The temperature increased from 50 to 90ºC, the λ of various specimens increased from 0.1024 to 0.2411 W/mK. The λ of wood is affected by changes in density, MC, and temperature, and increases with increasing density, MC, and temperature. The temperature influenced on the λ of various species was greater than that on the MC increased by the change of RH inferentially. The MC of wood species with different densities under different RH, and the effects of λ at different temperatures of wood; therefore, can be used as a reference for subsequent evaluation of λ as the domestic woods are used in interior materials in Taiwan.
