Experimental research on thermal comfort of Natural wind

In this paper,three airflow types and seven airflow forms from simulating system of natural wind were studied to understand how the thermal comfort was affected by air current of machine wind and natural wind in different environments.Also,the human's airflow sensation and thermal comfort of different machine wind and natural wind in varied environments were researched by human experimental method.The results showed that more than 90% testees can easily distinguish the differences between natural wind and machine wind,and 70% testees can tell the differences of natural wind in different environments.Under two different temperature environments,90% testees selected natural wind as their most favorite airflow mode.Furthermore,the integrated evaluation of natural wind is better than that of the other forms of airflow.
