In order to study the range of comfort environment parameters, subjective assessment and objective assessment are used in this research. The main purpose of this study is to determine the temperature and humidity range, acceptable temperature fluctuation, acceptable air flow rate and acceptable vertical air temperature difference under the thermal comfort environment in summer and winter. The thermal comfort environment should make the PMV between −0.5 and +0.5 which is recommended by international standard ISO7730. Following this principle, the comfort temperature ranges in summer and winter are determined respectively, comfort temperature range is 25–28 °C in summer and 22–25 °C in winter. Under the thermal comfort environment condition, the biggest acceptable temperature fluctuation is obtained and is 0.6 °C and the biggest acceptable air flow rate is 0.5 m/s in summer. In winter, if the vertical air temperature difference is higher than 3.2 °C, the subjects feel comfortable.
