Abstract
The thermal environment of atrium space is complex and its formation mechanism is special. The scientific evaluation of atrium space can help guide the development of appropriate ventilation and heating modes, reducing energy consumption and improving thermal comfort. Through field measurement and questionnaire, the indoor thermal environment and its un-uniform characteristics of the atrium space in winter, as well as the user's behavior habits and subjective thermal feeling are systematically analyzed. Statistical regression analysis method is used to fit and evaluate factors such as operative temperature and thermal comfort, quantitatively reveals the thermal environment needs of atrium users. The study demonstrate that the predicted thermal sensation vote is slightly cold, and the measured thermal neutral temperature of the occupants is lower than the predicted thermal neutral temperature. Furthermore, this study demonstrates the distribution of air temperature in horizontal direction and its influencing factors; in addition, reveals the trend of air temperature with time and height and establishes a fitting equation between air temperature and elevation. The data obtained in this study can provide valuable reference for the construction and operation of college atrium space in cold regions.
