Abstract

Air inlet and outlet configurations is done by opening or closing the oulet ventilation that near the ceiling or floor and providing 100% fresh air for ventilation. Air inlet and outler give significant effecet on thermal comfort. However, it is a method for achieving good ventilation of 100% fresh air. Conventional air conditioning systems evidently have shown a few several limitations in terms of their cost, energy conservation, environmental protection, climate change, industry standards and service. The main objectives of this project are to study the possibility of using HRC to provide 100% fresh air and to investigate the room temperature and air velocity by varying the configurations of air inlet and outlet. The objectives can be achieve by fabricate and experimental work. The most important parameter in this project are study room temperature and air velocity by air inlet and outlet configurations. Therefore, the displacement ventilation at second level will be acceptable with 0.1m/s until 0.16m/s. The result is obtaining by experimentally by measuring the temperature and velocity when varying air inlet and outlet. As a conclusion, the possibility of using HRC in Malaysia is possible. The results indicated that the room temperature was achieved around 24°C to 26°C by providing 100% fresh air. Otherwise, the room temperature was investigated by studying to vary configurations with the effect of chilled ceiling temperature which was affected by chiller water. The result obtained that room temperature is around 24°C to 26°C with the velocity around 0.10m/s to 0.16m/s. This comfort condition is achieved for the displacement ventilation case at second level of chilled ceiling panel.
