Environments conditioned by split-type systems present comfort conditions that may vary substantially according to the position of the equipment. In this work, the comfort conditions in a classroom were evaluated experimentally based on the PMV index, according to ISO 7730 Standard that defines the thermal satisfaction in occupied environments. Two split-type equipment were installed in two different positions of the room. For each position, three different supply airflows were tested. The results showed that there is a considerable variation in the air velocity field in the room as well as in the PMV values in the two situations for three different supply airflows, consequently there are a considerable variation in the thermal comfort indices. Therefore, it is possible to establish a control of the classroom thermal comfort only by varying the supply airflow.
