*1.1. Overview*

As an important part of university space, the classroom is the main place for students' daily study, and its indoor thermal environment directly affects students' comfort, physical and mental health, and learning efficiency.

The traditional way of creating a comfortable environment is by controlling the indoor environmental parameters within a specified range according to the relevant standards. However, the people's comforts are so different that these parameters cannot effectively meet individual states, feelings, and preferences. Additionally, individual comfort claims are not conveyed and feedback is not given during the creation of the thermal environment [1]. Therefore, it is necessary to propose reasonable and effective solutions in a targeted manner [2]. The present study provides a reasonable basis for the further improvement of indoor thermal comfort by summarizing and analyzing the results concerning thermal satisfaction through a subjective survey of student subjects.
