The human body keeps regular temperature regarding the human body's freshness.
For keeping freshness, heat generated from human body should emit outside of the body by air circulation, conduction,
emission, and evaporation. The human body feels freshness when the emission rate is 40~45%, which was emitted by a
radiation when it is comfortable and warm, and air circulation and conduction is 20~30%, and evaporation is 20~24%.
It sometimes may depends on seasonal factor, wearing condition, age, sex and mental state other than indoor environment.
But generally the value of fresh indoor temperature is that below 0.2(m/s) of indoor air circulation, the temperature is 21~28˚C
when the wall temperature is the same as the indoor's and relative humidity is 30~31% in summer, the winter temperature is
