ABSTRACT:
Disclosed are an air conditioning system, in which the total operating capacity of compressors is variably controlled in accordance with a cooling or heating load in a room, and a method for controlling the air conditioning method, thus improving comfortableness in the room, reducing an electric power consumption rate, and increasing cooling or heating efficiency. The air conditioning system includes an indoor heat exchanger for cooling a room by heat-exchanging a refrigerant with air in the room; an outdoor heat exchanger for condensing the refrigerant; a plurality of compressors for compressing the refrigerant; and a control unit for controlling operation of the plural compressors in accordance with the cooling or heating load in the room.
