Abstract (en)
[origin: EP2515055A1] To provide an air-conditioning apparatus that can prevent the formation of frost on indoor-side heat exchangers functioning as an evaporator even when the outside air temperature is low, and can use unmodified normal indoor units even when a portion of the indoor units is used in a place that has a large sensible heat load. An air-conditioning apparatus 100 capable of simultaneous heating and cooling operation includes a heat source unit A, a plurality of indoor units B, C, and D, and a relay unit E that connects the heat source unit A to the indoor units B, C, and D. Aflow control unit 31 that controls a flow amount of a refrigerant that flows through the indoor units that are in cooling operation is provided to a piping (a first connecting piping 21) on the downstream side of a merging section (a first branching unit 10) of a piping through which flows the refrigerant that flows out from the indoor units that are in cooling operation.
