Abstract (en)

[origin: EP3677856A1] A multi-type air-conditioning system includes an outdoor unit including an outdoor heat exchanger, a plurality of indoor units each including an expansion valve into which the refrigerant passing through the outdoor heat exchanger flows and an indoor heat exchanger configured to cause heat exchange to be carried out between the refrigerant decompressed by the expansion valve and air, and refrigerant piping which connects the plurality of indoor units in parallel to the outdoor unit, and through which the refrigerant flows. Part of the refrigerant piping positioned inside each of the indoor units includes a plurality of capillaries at a position on the upstream side of the expansion valve in the flow direction of the refrigerant, and the capillaries are connected in parallel to the refrigerant piping.
