摘要

Airflow fluctuation is an important factor effecting indoor thermal environment and human thermal response. In this paper, the dynamic airflows with different fluctuating characteristics are generated by controlling rotational speed of fans. The influence of three kinds of different airflows, constant airflow, imitating natural airflow and sinusoidal airflow, on thermal comfort is studied. The subjective experiments indicate that the dynamic airflow can cause stronger cold sensation, and that air movement with l/f fluctuations similar to natural wind is more comfortable than other dynamic airflows. Moreover, the draught impacts of different kinds of airflows are different in neutral-warm and cool-neutral thermal environments.
