Comfort in naturally ventilated student apartments in hot humid area of China in winter: An example study of Haikou

By the method of field test on indoor and outdoor environmental parameters and the questionnaire survey of thermal comfort, measures and analyses thermal environment and human thermal sensation in the student apartments in winter. Obtains the relationships between the SET (standard effective temperature) and MTS (mean thermal sensation) using regression analysis. The results show that the measured and predicted thermal neutral temperatures are 23.36 ℃ and 25.60 ℃, respectively, while the preferred temperature of subjects is 26.50 ℃. The acceptable temperature range for 90% and 80% of subjects are 20.09-26.63 ℃ and 17.80-28.92 ℃, respectively, which exceeds the limits of the comfort zone in ASHRAE 55.
