Item INVESTIGATION OF THE EFFECTS OF MOOD STATES ON USERS’ THERMAL COMFORT(2022-06-14) ÇETER, Aydın Ege; TURHAN, Cihan; ALKAN, NeşeProviding indoor thermal comfort to the users has a great importance since most of the people spend 90% of their time in interior zones. On the other hand, accurate calculation of the thermal comfort has been a problematic issue and is the first priority in providing thermal comfort. Recent studies in this field have shown that there is a vital difference between the calculated thermal comfort and thermal sensation. Additionally, researchers have investigated the effects of human psychology, which is thought to be one of the important reasons for this difference. However, ongoing studies have only addressed the physical responses of the human body under psychological disturbance. Moreover, the mood state of the people is an important parameter of the human psychology. Therefore, this thesis investigates the effect of mood states on users’ thermal sensation and offers a novel “Mood State Correction Factor (MSCF)” on the existing thermal comfort model. For this reason, a series of experiments were conducted in a study hall of Atılım University between 16th of August, 2021 and 15th of April, 2022. Predicted Mean Vote (PMV), Actual Mean Vote (AMV) and Profile of Mood States (POMS) were used to investigate the effect of mood state on the thermal sensation. The results of the study indicated that the most effective mood state classes on thermal sensation of the users are very pessimistic, very optimistic and pessimistic, moreover, the users feel significantly warmer than the measurement results. Additionally, the MSCFs are calculated as -0.125, -0.114 and -0.075 for very pessimistic, very optimistic and pessimistic mood state classes, respectively.
