Abstract:
A scroll compressor and an air conditioner including a scroll compressor are provided. The scroll compressor may include a main frame configured to support an upper portion of a rotating shaft; a fixed scroll coupled to the main frame and having a first wrap; an orbiting scroll provided to perform an orbiting motion with respect to the fixed scroll and having a second wrap which forms a plurality of compressions chamber between the first wrap and the second wrap; a suction port configured to enable a first refrigerant to be suctioned into the compression chamber; a first introduction port provided at a first side of the fixed scroll and configured to inject the first refrigerant into the plurality of compression chambers; a second introduction port provided at a second side of the fixed scroll and configured to inject a second refrigerant having a pressure different from a pressure of the first refrigerant into the plurality of compression chambers; and a third introduction port provided at a third side of the fixed scroll and configured to inject a third refrigerant having a pressure different from the pressure of the first refrigerant and the second refrigerant into the compression chamber. The first introduction port may be provided at a position at which injecting of the refrigerant through the first introduction port is able to be performed before suctioning of the refrigerant through the suction port is completed.
Abstract:
An air conditioner includes a compressor, an outdoor heat exchanger, an indoor heat exchanger, a converting unit, an accumulator, and injection module, a supercooling valve, and an injection valve. The injection module expands and vaporizes a portion of refrigerant flowing from the indoor heat exchanger to the outdoor heat exchanger in the heating operation. The supercooling valve is disposed between the injection module and the accumulator and is opened to direct the portion of the refrigerant vaporized in the injection module to the accumulator in the heating operation and then closed after a predetermined time passes. The injection valve is disposed between the injection module and the compressor and is opened when the supercooling valve is closed in the heating operation, thereby injecting the portion of the refrigerant vaporized in the injection module to the compressor.
Abstract:
An air conditioner may include a case having a supply channel therein through which external air flows into an interior space; a first heat exchanger disposed on the supply channel and in which the air and refrigerant exchange heat; a second heat exchanger disposed at a downstream side of the first heat exchanger in the supply channel, and in which the air and refrigerant exchange heat; and a refrigerant distributor that sends refrigerant to the first heat exchanger or the second heat exchanger. The refrigerant distributor may include a liquid pipe connected with the first heat exchanger and through which liquid-state refrigerant flows; a first gas pipe connected to the first heat exchanger and the second heat exchanger and through which gas-state refrigerant flows; a second gas pipe through which gas-state refrigerant discharged from the first heat exchanger flows; a first gas pipe valve disposed on the first gas pipe and that sends refrigerant flowing through the first gas pipe to the first heat exchanger or the second heat exchanger; and a second gas pipe valve disposed on the second gas pipe and that opens and closes the second gas pipe.
Abstract:
An air conditioner is provided. The air conditioner includes a compressor having a suction unit and a plurality of injection inlets, an inside heat exchanger into which refrigerant compressed in the compressor is introduced during a heating operation, an outside heat exchanger into which refrigerant compressed in the compressor is introduced during a cooling operation, a plurality of refrigerant separation devices through which refrigerant condensed in the inside heat exchanger or the outside heat exchanger pass, a plurality of injection flow paths which extends from the three refrigerant separation devices to the plurality of injection inlets, and a bypass flow path which extends from any one injection flow path among the plurality of injection flow paths to the suction unit of the compressor.

Abstract:
A scroll compressor and an air conditioner including a scroll compressor are provided. The scroll compressor may include a casing, a fixed scroll, an orbiting scroll, and an injection passage. The fixed scroll may further include a first injection hole and a second injection hole formed on a spiral flow passage, and a third injection hole and a fourth injection hole formed on the spiral flow passage at a position inwardly rotated by about 360 degrees from the first injection hole and the second injection hole along the spiral flow passage. The first injection hole and the third injection hole may be formed on an outer lane of the spiral flow passage, and the second injection hole and the fourth injection hole may be formed on an inner lane of the spiral flow passage.
Abstract:
An air conditioning system that includes at least one indoor unit that uses water as a working fluid, an outdoor unit that uses a refrigerant as a working fluid, the outdoor unit including a compressor compressing the refrigerant and an outdoor heat exchanger for heat-exchange with the refrigerant, and a heat collection unit connecting the at least one indoor unit to the outdoor unit, the heat collection unit including at least one heat exchange part for heat-exchanging water supplied from the at least one indoor unit with the refrigerant supplied from the outdoor unit.
Abstract:
Provided are a scroll compressor and an air conditioner including the same. The scroll compressor includes a motor, a driving shaft, a main frame, a fixed scroll, an orbiting scroll, a suction, a first inflow part disposed on one side of the fixed scroll to inject the refrigerant into the compression chamber, and a second inflow part disposed on the other side of the fixed scroll to inject a refrigerant, which has a pressure different from that of the refrigerant introduced into the first inflow part, into the compression chamber. The first inflow part is disposed at a position at which a first extension line (l1) connecting a central portion of the fixed scroll to a central portion of the suction part rotates by a first preset angle in a direction opposite to the rotation direction of the compression chamber.
