| 摘 要： | 本文对动态送风末端装置在稳态和动态条件下的送风特性、温度特性与换热进行了实验研究。结果表明 ,该末端装置在动态化送风时 ,出风温度也呈现动态化 ,并且风量较大时出风温度较高 ,风量较小时出风温度较低。对出风风速进行频谱分析 ,动态风的频谱与自然风的频谱非常相似。由于送风的动态化 ,动态末端装置的出风速度和换热量均有所减小 ,在干工况下减小程度小于 3 %。也就是说 ,风速的动态化对动态送风末端装置的风量和传热影响很小

| Abstract: | A new fan-coil unit (FCU) with a moving guide (swing)plate has been studied experimentally. The paper presents the results on characteristics of unsteady fan-coil unit, which is able to provide fluctuating airflow and variable air temperature as well. The results gaied from the experimint showed that the spectrum of supply airflow is similar to the spectrum of natural wind, and that the supply air temperature is changed with the airflow. Owing to the unsteady air supply, both the airflow rate and the cooling capacity if the unit are decreased up to 3% in the case of dry coil. |
