Influences of Environmental Humidity on Subjective Thermal Comfort Under the Neutral Room Temperature of Thermal Sensation

Abstract

The discussion about indoor humidity has been conducting extensively. This paper examines influence of environmental humidity on thermal comfort based on the subjective evaluation by sensory tests. The neutral range of dryness sensation is marked out at humidity of 42%RH to 58%RH in summer and of 33%RH to 67%RH in winter. Subjects give wide latitude in winter humidity compared to summer.
