(EN) The multi-type air conditioning system according to the present invention includes: an outdoor unit having an outside air heat exchanger; a plurality of indoor units each having an expansion valve into which a refrigerant flows after passing through the outdoor heat exchanger, and an indoor heat exchanger which exchanges heat between the refrigerant decompressed by the expansion valve and air; and a refrigerant pipe which connects the plurality of indoor units in parallel to the outdoor unit and through which the refrigerant flows. The refrigerant pipe located inside each of the indoor units has a plurality of capillaries at the location upstream of the expansion valve and along the flow direction of the refrigerant, and the capillaries are connected in parallel to the refrigerant pipe.
