Air-conditioning apparatus

An air-conditioning apparatus comprising:

• a compressor into which an intermediate-pressure refrigerant is allowed to be injected via an injection pipe in the course of compressing a refrigerant;
• an outdoor heat exchanger;
• a flow passage switching device that switches connection of the outdoor heat exchanger;
• an injection flow rate control device that controls a flow rate of injection into the compressor;
• an outdoor-side flow rate control device that generates an intermediate pressure for injection into the compressor and that is able to change a flow passage resistance in a continuous manner;
• a bypass flow rate control device that is placed at a bypass pipe which allows bypassing of the outdoor heat exchanger in parallel to the outdoor-side flow rate control device, that controls an amount of heat exchange of the outdoor heat exchanger, together with the outdoor-side flow rate control device, and that is able to change a flow passage resistance in a continuous manner;
• an indoor heat exchanger;
• and
• an indoor-side flow rate control device that adjusts a flow rate of refrigerant to the indoor heat exchanger,
• wherein the compressor, the outdoor heat exchanger, the flow passage switching device, the injection flow rate control device, the outdoor-side flow rate control device, and the bypass flow rate control device are provided within an outdoor unit,
• wherein the indoor heat exchanger and the indoor-side flow rate control device are provided within an indoor unit, and
• wherein the indoor unit includes a plurality of indoor units, which are connected to the outdoor unit in parallel.
