| 概要 |
The heat transfer and thermal efficiency of Paulownia coreana (low–density wood) and high–density fiber board were measured via a comparative analysis of heat transfer, and the suitability of the wood... as a finishing material was evaluated. A comparative analysis of heat transfer is calculated by verifying the heat transfer and change in temperature of the water bottle both inside and outside of the sample box. The total transferred heat is then divided by conduction, convection, and radiation. The results show 18.05 W of heat was transferred to water bottle in the low–density Paulownia coreana UYEKI, and 12.5 W in the high–density fiberboard. The total heat from the heating source was 30W. This indicates that a heat loss of low density wood was smaller than that of high density fiberboard. A difference was found in the amount of heat transferred, with a majority due to radiation: 0.02 W of conduction, 1.5 W of convection, and 3.98 W of radiation. These results indicate that the low density wood is appropriate for use as a thermal insulation building material.続きを見る
