More Information
Summary:An air conditioning apparatus comprises an air-conditioning unit including at least a cooling coil as a heat exchanger, a blower, a chiller, and a coolant pump for conducting air-conditioning, wherein the coolant pump pumps the coolant cooled by the chiller to the cooling coil, the cooling coil cools the air through heat exchange of the coolant and the air, the blower supplies the cooled air into a room. Coolant temperature of the chiller, the coolant flow rate of the coolant pump, and the air flow rate of the blower are calculated in accordance with the set points of the indoor temperature and the indoor humidity, and the chiller, coolant pump, and blower are controlled on the basis of the arithmetic calculation results. Thereby, the indoor temperature and indoor humidity are independently controlled in the central air-conditioning system.
