Human thermal comfort research in hot- humid area of China (3)—Comparison between winter and summer

Using the classic thermal comfort research methodology, performs a climate chamber experiment to study the examinees’ responses in naturally ventilated buildings in hot- humid area of China both in summer and winter. Makes psychological and physiological response comparison between the two seasons. The obtained seasonal variations are that thermal sensation in winter keeps the same as in summer, but thermal comfort and acceptability become poor under cool environments and improve under warm environments. Besides, the heart rate and skin temperature are higher in winter than in summer, and the skin wetness is lower under warm environments. The variations provide important evidences for psychological adaptation and physiological acclimatization of people in hot- humid regions.
