The Effects of Indoor Air Speed on the Thermal Comfort of Human Body in Winter

Abstract:

Air speed affects convective and evaporative heat losses from the human body. Some physiological parameters such as conduction speeds of nerves and body temperature are considered to can directly indicate the responses of human body to air speed. The aim of this paper is to seek the appropriate physiological parameters and acquire the primary affected trends. The research methods included questionnaire, physic test, and physiology test. Through changing the indoor air speed, tested the body temperature, conduction speeds of sensory nerve and motorial nerve of the subjects and recorded the subjects subjective thermal senses. With the increase of blowing time, the conduction speeds of sensory nerve and motorial nerve both tend to diminish. The thermal senses vote changes quickly from neutrality to light cool and cool. This experiment also shows thermal comfort senses can be expressed with the quantification form of the physiology indexes.
