Taking a large integrated shopping mall in Guangzhou as the research object, carries out the indoor thermal comfort research through the questionnaires and field measurement in winter. Conducts a statistical regression analysis on the survey data. The results show that the measured thermal neutral temperature of the mall in winter is 19.4 ℃, and the thermal comfort temperature which meets a satisfaction degree of 90% ranges from 16.1 ℃ to 22.7 ℃. Meanwhile, the indoor thermal neutral temperature calculated by PMV model is 16.8 ℃, and the thermal comfort temperature which meets a satisfaction degree of 90% ranges from 13.3 ℃ to 20.4 ℃.The thermal sensation predicted by the PMV model is much higher than the actual thermal feeling. Based on the survey data, analyses the correlation between the indoor thermal neutral temperature and outdoor air temperature, and establishes the approximate linear relationship between the mall’s indoor thermal neutral temperature and outdoor air temperature. Sets up a winter thermal comfort climate adaptation model for the shopping mall.
