Field study on occupant thermal comfort in residential buildings of Jiaozuo city in summer

Studies the thermal comfort of occupants in mixed cooling mode in a synchronous way of the field measurement and questionnaire survey. The results show that the measured thermal neutral temperature and predicted thermal neutral temperature is 27.7 ℃ and 25.2 ℃ respectively in this area in summer; the upper limit of the operative temperature corresponding to the accepted thermal environment by 80% of the occupants is 28.8 ℃ and 29.2 ℃ respectively, and the preferred temperature is 27.4 ℃ and 24.0 ℃ respectively, obtained from the thermal sensation method and direct inquiry method; Because of the condition of entering a non-air conditioned space from an air-conditioned space existing in the mixed cooling mode, the dissatisfied percent with the thermal environment is higher than that in natural ventilation mode, and the upper limit of the acceptable temperature is lower than that in natural ventilation mode.
