The ASHRAE scale, (3) cold, (2) cool, (1) slightly cool, (0) neutral, (+1) slightly warm, (+2) warm and (+3) hot, was used for the assessment of subjects’ thermal sensation for overall body.
Thermal comfort was assessed using the Bedford’s scale.
Visualanalog scales as shown in Fig. 2 were used in the assessment. Scale A was used to assess odor intensity and irritations. Scale B was used to assess PAQ acceptability.
Scale C was used to assess dry air sensation and freshness.
