动态送风装置的试验研究
Experimental studies on dynamic cupboard type air terminals
摘要：
该装置用步进电动机带动分流板产生动态风。热工性能试验显示，与稳态送风相比，风速动态化后对风量和换热量影响很小。以大学生为试验样本进行了人体舒适性研究，显著性分析表明，受试者对动态风接受程度较稳态风有显著提高。

Abstract：
The device creates dynamic air supply with stepper motor driving flow distribution plates. The results of the thermal performance test show that the dynamic air supply has little influence on airflow and cooling capacity of the air conditioning units compared with stable air supply. Studies the comfort taking undergraduate students as samples, and the results show that the acceptability of human subjects to dynamic airflow is significantly higher than that to stable airflow.
