Subjects felt warm and slightly uncomfortable in the uniform conditions and face thermal sensation was equal to overall thermal sensation. When face cooling was supplied, face thermal sensation dropped immediately from warm to slightly cool, and overall thermal sensation dropped as well from warm to slightly warm and overall thermal comfort changed from slightly uncomfortable to slightly comfortable. After the first moment of face cooling, subjects’ thermal responses changed gradually and slightly and reached almost constant at the end of exposure. In order to test whether the responses reach steady state or not, repeated measure ANOVA and paired-sample t-tests were performed based on the normal distribution test (Shapiro–Wilk’s W test) of the data and it was found that the responses obtained in all conditions reached steady state within 20min (p>0.05). Therefore the subjects’ responses were divided into three groups: responses to steady and uniform conditions (the first two votes), responses to dynamic conditions (the 3rd vote to the 15th vote) and responses to steady and non-uniform conditions (the last three votes). It can be also
