Background: In general, it can be said that this thesis is in the field of thermal comfort. Thermal comfort is a subjective condition that reflects an individual's satisfaction with the surrounding thermal environment. More specifically, the issue addressed in this research is the analysis of thermal comfort in a classroom at the Persian Gulf University in Bushehr and the examination of methods to improve thermal comfort in this environment. To achieve this, thermal comfort models and indices are required. A thermal comfort model predicts the acceptable environmental conditions for different environments, while thermal comfort indices are generally defined to quantify the criteria of thermal comfort. In this study, the PMV model by Fanger is used, which defines two main indices: the Mean Vote (PMV) and the Percentage of People Dissatisfied (PPD) with the thermal conditions of the environment.
Objective: It should be noted that assessing thermal comfort in classrooms is of particular importance. The main necessities related to this include ensuring health, assisting in the learning process of students, and reducing energy consumption. Indoor environments without comfort negatively affect the learning process and motivation of participants in educational activities, leading to problems with students' ability to concentrate, learn, remember, and think. Therefore, the main objective of this research is to assess whether thermal comfort is achieved for the students in the classroom and to improve their comfort conditions by making adjustments to the environment. Another goal of the study is to examine the thermal comfort status during different class hours and the impact of solar radiation entering through the windows on thermal comfort.
Methodology: From a methodological perspective, this research is a "case study." The method and tools used for this case study include computational fluid dynamics (CFD) techniques and thermal environment simulations using the Airpak sof
