Air conditioner

An air conditioner comprising:

• a scroll compressor to compress a refrigerant, the scroll compressor having a fixed scroll, an orbiting scroll, a suction unit, a plurality of injection inlets, and a discharge cover;
• an inside heat exchanger into which the compressed refrigerant is introduced during a heating operation;
• an outside heat exchanger into which the compressed refrigerant is introduced during a cooling operation;
• a plurality of refrigerant separation devices through which a refrigerant condensed in the inside heat exchanger or the outside heat exchanger pass, the plurality of refrigerant separation devices including first, second, and third refrigerant separation devices;
• a plurality of injection flow paths to extend from the plurality of refrigerant separation devices to the plurality of injection inlets, the plurality of injection flow paths including a first injection flow path coupled to the first refrigerant separation device, a second injection flow path coupled to the second refrigerant separation device, and a third injection flow path coupled to the third refrigerant separation device;
• and
• a bypass flow path to extend from one of the plurality of injection flow paths to the suction unit,
• wherein the plurality of injection inlets include:
• a first inlet that passes through the discharge cover and is coupled to a first position of the fixed scroll to inject the refrigerant into a compression chamber, the first inlet being coupled to the first injection flow path;
• a second inlet that passes through the discharge cover and is coupled to a second position of the fixed scroll to inject the refrigerant into the compression chamber, the second inlet being coupled to the second injection flow path;
• and
• a third inlet that passes through the discharge cover and is coupled to a third position of the fixed scroll to inject the refrigerant into the compression chamber, the third inlet being coupled to the third injection flow path,
• wherein the first, second and third position are formed at a different position with one another.
