    Abstract

    Subjective experiments were conducted in a climate chamber for the purpose of evaluating human comfort under the transient conditions due to cyclic air temperature swing at the constant absolute humidity. Eight Japanese subjects were exposed for 120 minutes. Two levels of absolute humidity were set at 28°C, 4.2g/kg(DA) and 11.8g/kg(DA). For each absolute humidity, 3 types of air temperature swing were examined keeping the constant absolute humidity, 28 °C ± 3.5 °C, ± 1.7 °C and ± 0 °C (without swing). As a result, it was revealed that absolute humidity level affected subjects' skin moisture, dryness sensation under same air temperature swing pattern. However, negative effects on human comfort were not found even at low absolute humidity under air temperature swing. The type of air temperature swing was not significant factor associated with physiological and psychological reactions to humidity at the same moisture content in the air.
