Abstract (en)

[origin: EP2905560A1] An air-conditioning apparatus 1 that includes a compressor 101, a heat-source-side heat exchanger 103, a plurality of use-side heat exchangers 105, and a relay unit B which switches part of the plurality of use-side heat exchangers 105 to the cooling operation side and which switches part of the plurality of use-side heat exchangers 105 to the heating operation side and that performs a cooling and heating simultaneous operation by switching each of the plurality of use-side heat exchangers 105 to the cooling operation side or the heating operation side in accordance with a control instruction, includes a second flow rate control device 122 which adjusts the flow rate of the refrigerant flowing into the compressor 101, a third flow rate control device 123 which is connected in parallel to the third flow rate control device 123 and which adjusts the flow rate of the refrigerant flowing into the heat-source-side heat exchanger 103, and a controller 141 which adjusts the second flow rate control device 122 and the third flow rate control device 123. The controller 141 adjusts the opening degree of the second flow rate control device 122 and the opening degree of the third flow rate control device 123 in accordance with the outside air temperature.
