木质单扇防火门的隔热性能分析

Heat Transfer Analysis of a Wooden Fire-Retardant Door

防火门的隔热性能多是通过耐火试验评价,目前尚未形成与之配套的理论计算公式。本研究以一款木质单扇防火门为例,以耐火试验为依据,综合相关学科知识,推导防火门隔热性能的理论计算公式。结果表明:防火门隔热性能的理论计算结果与耐火试验结果相符,理论计算公式可为防火门隔热性能评价,提供依据和参考。

Heat transfer of fire retardant wooden structures was evaluated with a standard fireproof test.The authors used a single wood-framed fire-retardant treated door as an example to develop a formula to predict heat transfer during the fireproof test.They found that the actual predicted result correlated well with the test results.Hopefully,the theoretical formula will provide some help to understanding heat transfer through a wooden fire retardant treated door.
