研究了分体空调动态化送风装置。频谱特征分析表明,该装置可在风口和人员活动区产生与真实自然风信号接近的动态气流。通过气候室实验研究了等温送风工况下,不同背景温度时人体对气流的需求,并比较了仿自然风与稳态机械风(简称稳态气流)对人体热舒适的影响。结果表明,在28℃和30℃工况下,分别采用0.4~0.6 m/s 和0.7~0.9 m/s 的风速可以满足人体热舒适需求;相比于稳态气流,仿自然风具有更强的冷作用和更好的接受度,60%以上的受试者喜好仿自然风。
研究瞭分體空調動態化送風裝置。頻譜特徵分析錶明,該裝置可在風口和人員活動區產生與真實自然風信號接近的動態氣流。通過氣候室實驗研究瞭等溫送風工況下,不同揹景溫度時人體對氣流的需求,併比較瞭倣自然風與穩態機械風(簡稱穩態氣流)對人體熱舒適的影響。結果錶明,在28℃和30℃工況下,分彆採用0.4~0.6 m/s 和0.7~0.9 m/s 的風速可以滿足人體熱舒適需求;相比于穩態氣流,倣自然風具有更彊的冷作用和更好的接受度,60%以上的受試者喜好倣自然風。

Develops the dynamic air supply device of split air conditioning to produce simulated natural wind(SNW),and the spectrum analysis results are very close to natural wind in occupied zone.Performs the climate chamber experiments to reveal the occupants ’ demand for air movement in different temperature environment and to compare the impacts of constant mechanical wind(CMW)and SNW on human thermal response.The results indicate that it is possible for subjects to remain thermal comfort in warm conditions of 28 ℃ and 30 ℃ with airflows,and the corresponding most suitable air velocity range is 0.4~0.6 m/s and 0.7~0.9 m/s,respectively.Compared with CMW,SNW can provide stronger cooling effect and better thermal comfort performance,which contributed to the consequence that over 60%subjects preferred SNW.
