Abstract During the past few decades, both positive and negative aspects of indoor air movement on human comfort perception have been studied. However, most research has focused on collecting empirical evidence to support the potential application of airflows in practice. In this context, numerous studies have encouraged the use of moving air to promote comfort in warm environments, especially with regard to the application of dynamic airflows. Through these studies, the effects of different airflow parameters (such as air velocity, turbulence intensity, and fluctuation frequency) on human comfort perception have gradually been identified and even quantified. This article aims to summarize the progress in the literature concerning dynamic characteristics and comfort assessment of airflows in four main sections: demand for indoor airflows, parameters of indoor airflows, comfort assessment of indoor airflows, and dynamic airflows and their application. This paper will hopefully aid the understanding of human perception of indoor airflows and guide future research.

Highlights • This article reviews the researches in indoor air movement comfort assessment. • Air movement can improve occupants' thermal comfort in warm environment. • Different airflow parameters can influence human thermal perception. • Simulated natural wind has better comfort effects than constant mechanical wind.
