Abstract

An air conditioning system provided which has: an outdoor device including at least a compressor and a first heat exchanger; an air handling device including an air supply fan and a second heat exchanger; an expansion valve; and a control section, wherein the compressor, the first heat exchanger, the expansion valve, and the second heat exchanger are sequentially connected in an annular shape to form a refrigerant circuit in which refrigerant circulates, and the control section adjusts a rotation speed of the air supply fan and/or a degree of opening of the expansion valve based on information including a temperature detection value of refrigerant on each of one end side and the other end side of the second heat exchanger, a temperature detection value of air toward the second heat exchanger, and a temperature detection value of air heat-exchanged by the second heat exchanger.
