If control the humidity, temperature, and air circulation in a space, need an air conditioning (AC) system. When an air conditioner successfully maintains a pleasant temperature in a room, say that it is doing well. One setting where instruction and study take happen is in university lecture halls. Typically, a classroom may accommodate from twenty to fifty students. It is recommended that classrooms be constructed as enclosed spaces in order to minimize outside noise. Unequal distribution of air circulation and temperature is a common issue in classrooms. The course model at Yogyakarta's Sekolah Tinggi Teknologi Nasional (STTNAS) is used to conduct numerical simulations in this study. The classroom's air conditioning system is equipped with two or three split-type units. This investigation of the classroom's velocity and temperature distribution involves relocating the air conditioner. The four scenarios include different locations for the air conditioner. To study the distribution of air velocity, pressure, and temperature, the classroom model is numerically simulated using ANSYS Fluent software using a transient pressure-based solver. For 10 minutes, the room is modelled with the inlet temperature of 16 ºC and an intake velocity of 0.5 m/s. The mean temperature of the classroom was unaffected by relocating the air conditioner, according to computer calculations. A temperature of 27.9 ºC is recorded in cases 1 and 2, while 27 ºC is recorded in cases 3 and 4.
