摘　　要：在人工气候室对受试者进行了3种不同湍流强度模拟自然风气流的人体热舒适实验,通过受试者的主观投票,比较了人体在工作和休闲两种状态下对不同湍流强度模拟自然风气流的热反应。结果表明,不同湍流强度模拟自然风下,人体热舒适性有较大差异,湍流强度过大的模拟自然风会恶化吹风感,降低人体热舒适性;在中性-热环境中,波幅适中、变化平稳、湍流强度适中的模拟自然风对改善人体热舒适最为理想;在中性-热环境中,休闲状态下受试者对所处环境气流的接受度要高于工作状态。Experimentally investigates the influence of simulated natural wind with three different turbulence intensities on human thermal comfort of the participants in a climate chamber. Compares the thermal reaction of the participants to different simulated natural winds in both rest and working states by subjective questionnaires. The results indicate that human thermal comfort is significantly different under simulated natural wind with different turbulence intensities, and relatively strong turbulence intensity would deteriorate thermal comfort due to uncomfortable draught sensation; in a neutral to warm environment, the simulated natural wind with moderate amplitude and turbulence intensity and smooth change is very helpful to impove human thermal comfort; in a neutral to warm environment, the participants show better acceptance of airflow in a rest state than that in a working state.
