Abstract

The present invention relates to an air conditioning system and a control method thereof capable of optimally controlling the flow rate of refrigerant flowing to a heat exchanger exchanging heat with indoor air. The air conditioning system includes: an outdoor heat exchange part, including: a compressor for compressing refrigerant; an outdoor heat exchanger for exchanging heat between the refrigerant and outdoor air; and an expansion device for expanding the refrigerant; an exchanging section comprising: a pump for making the refrigerant flow in a flow path other than the outdoor heat exchanging section; at least one indoor heat exchanger for exchanging heat between the refrigerant and indoor air; and a flow rate control device for controlling refrigerant flow rate; and a mixing heat exchanging part for exchanging heat between the outdoor heat exchanging part and the indoor heat exchanging part which are independent of each other. As long as the power of the pump allows, the air conditioning system can be installed in multi-storey buildings regardless of building height; it can also be applied to systems with longer refrigerant pipelines, and can precisely control the indoor air temperature.
