Patent ID: 8881548

Claim:
An air-conditioning apparatus comprising: a heat-source-side refrigerant cycle in which a compressor, an outdoor heat exchanger, a plurality of intermediate heat exchangers, and a first refrigerant flow control device disposed between each of the intermediate heat exchangers are connected in series, and a first bypass pipe which bypasses the first refrigerant flow control device through a first opening/closing device is disposed; and a plurality of use-side refrigerant cycles in which a plurality of indoor heat exchangers are connected in parallel with the plurality of intermediate heat exchangers, respectively, wherein the compressor and the outdoor heat exchanger are disposed in an outdoor unit; the plurality of intermediate heat exchangers, the first refrigerant flow control device, the first bypass pipe, and the first opening/closing device are disposed in a relay unit; the indoor heat exchanger is disposed in each of a plurality of indoor units; each of the plurality of intermediate heat exchangers exchanges heat between a heat-source-side refrigerant circulating through the heat-source-side refrigerant cycle and a use-side refrigerant circulating through the use-side refrigerant cycle.
