Abstract This study developed a program for detecting charged refrigerant amount in system air-conditioner. System air-conditioner is an air-conditioning system with multiple in-door units. Due to the complexity of the system, it is more difficult to detect the refrigerant amount charged in the system air-conditioner than in a general single air-conditioner. Experi-ments were performed for a 6HP outdoor unit with 3 indoor units in a psychrometric calori-meter. The experimental amount of the charged refrigerant was ranged from 60% to 140% with 10% increasement. Fuzzy algorithm was employed for detecting the charged refrigerant amount in the system air-conditioner. The experimental data were used for curve-fitting for the general ranges of indoor and outdoor temperature conditions. Membership function was determined for the whole ranges of experimentally measured data and rule-bases were defined for each charged refrigerant amount. Developed program successfully predicted the measured data within 10% resolution range.Keywords:Charged refrigerant am
