An Experiment and Simulation of the Affecting of Indoor Unit Location on Temperature Distribution in the Small Narrow Area

In the current situation of educational development and the need for higher education, universities in developing countries are increasingly expanding in size and being invested in facilities. The classrooms have air conditioning systems to help students have a better, more comfortable, and quality learning environment. However, the equipment and construction are still based on emotions; studies or tests have yet to be conducted on the factors causing temperature distribution in the classroom. This is the reason why this study was done. The factors surveyed and considered here are the set temperature for the room, the supply wind speed at the inside heat exchanger, the time of day, the size and dimension, the height of the room wall, and the area of the glass covering the room. After building a model, simulated by computational fluid dynamics software (CFD) ANSYS Fluent, conducting experiments, applying theoretical calculations, and statistical analysis, the results show that the effects of the location of the indoor heat exchanger unit keep the leading role for the temperature distribution of the room. Thereby also showing the reasonableness of the results and giving the best plan for setting parameters so that the environment in the room can reach the comfort zone of learners to save operating costs and reduce energy consumption, which impacts global warming.
