A study of performance analysis of fan coil unit system for FKM's air conditioner

Air conditioning system is a process of ventilation, air movement, air cleanliness, dehumidifying and cooling in order to give comfort to occupant. In tropical climate countries like Malaysia, air conditioner is very important to cool building space. Currently, most of commercial building in Malaysi...

The percentage comparison heat gain against cooling coil load with load for Briefing Room 8 and Lecture Room 5 are 34.45 % and 47.98 % less than the heat gain by rooms.
