Indoor thermal and humidity environment and thermal adaptation in different heating periods of North China

Analyses the variations of indoor environmental parameters and the laws of human thermal adaptation during the heating period and before and after the heating period in winter of North China based on the measurements of environmental parameters in students dormitory and the subjective feedback evaluation of the occupants on the indoor temperature and humidity. The results show that the thermal sensation in different heating periods is influenced by the temperature difference between indoor and outdoor, which leads to different thermal evaluations for the same indoor thermal environment. The relationship between thermal sensation and operative temperature can reflect thermal adaptation to some extent. The humidity adaptation is not obvious because people are not sensitive to humidity.
