20130055749 | AIR CONDITIONER - Provided is an air conditioner. The air conditioner includes a compressor, a condenser, an expansion device, an evaporator, and a supercooling device configured to supercool a refrigerant passing through the condenser. The supercooling device includes a supercooling main body in which the refrigerant passing through the condenser and a refrigerant to be injected into the compressor are introduced, a first passage disposed within the supercooling main body so that the refrigerant passing through the condenser flows in one direction, a second passage disposed on a side of the first passage so that the refrigerant passing through the condenser flows in the other direction, and a third passage in which the refrigerant to be injected into the compressor flows, the third passage being heat-exchanged with at least one of the first and second passages. | 03-07-2013 |
20130055753 | AIR CONDITIONER - Provided is an air conditioner. The air conditioner includes a compressor, a condenser, a super cooling device, and an evaporator. The super cooling device includes: a first flow passage disposed in the super cooling device to guide the refrigerant coming from the condenser toward the evaporator; and a second flow passage located in the super cooling device for exchanging heat with the first flow passage and guiding the refrigerant toward the compressor. One of the first and second flow passage includes: a distribution part configured to divide a flow of the refrigerant; and an inner tube connected to the distribution part. A stream of the refrigerant flowing in the first flow passage exchanges heat with a stream of the refrigerant flowing in the second flow passage while using an outer surface area of the inner tube as a heat exchange area. | 03-07-2013 |
20130055754 | AIR CONDITIONER - Provided is an air conditioner. The air conditioner including a compressor for compressing a refrigerant, a condenser for condensing the refrigerant compressed by the compressor, a phase separator for separating a gaseous refrigerant from the refrigerant passing through the condenser, and an evaporator for evaporating the refrigerant passing through the phase separator includes an inflow part provided in the phase separator to introduce the refrigerant into the phase separator, a gas separation part configured to discharge the gaseous refrigerant separated by the phase separator, an injection passage configured to inject the refrigerant discharged from the phase separator into the compressor, and an internal heat-exchanger provided within the phase separator to heat-exchange a refrigerant therein with the refrigerant introduced through the inflow part. | 03-07-2013 |
20130081425 | SCROLL COMPRESSOR AND AIR CONDITIONER INCLUDING THE SAME - The scroll compressor includes a fixed scroll including a first wrap, an orbiting scroll disposed to have a phase difference with respect to the fixed scroll, the orbiting scroll including a second wrap defining a compression chamber together with the first wrap, a suction part to receive a refrigerant into the compressor chamber, a driving shaft to transmit a rotation force to the orbiting scroll, a first injection part disposed in one position of the fixed scroll to introduce a refrigerant into the compression chamber, and a second injection part disposed in another position of the fixed scroll to introduce a refrigerant into the compression chamber, where the second wrap is disposed on the orbiting scroll such that the first injection part is opened to introduce the second refrigerant before the receipt of the first refrigerant through the suction part is completed during the orbiting of the orbiting scroll. | 04-04-2013 |
20130219927 | AIR CONDITIONER AND CONTROL METHOD THEREOF - Provided is an air conditioner. The air conditioner including a compressor, an outdoor heat exchanger, an indoor heat exchanger, and an expansion device includes a supercooling device for supercooling a refrigerant condensed in the outdoor heat exchanger or the indoor heat exchanger, an injection passage through which the refrigerant passing through the supercooling device is introduced into an injection inflow part of the compressor, a bypass passage extending from the injection passage to a suction part of the compressor to bypass the refrigerant, and a passage opening/closing part disposed in at least one of the injection passage and the bypass passage to selectively block a flow of the refrigerant. | 08-29-2013 |
20140305144 | AIR CONDITIONER AND METHOD FOR CONTROLLING THE SAME - 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. | 10-16-2014 |
20140305150 | AIR CONDITIONER AND METHOD FOR CONTROLLING THE SAME - An air conditioner includes a compressor, an outdoor heat exchanger, an indoor heat exchanger, a converting unit, a first injection module, and a second injection module. The first injection module injects a portion of refrigerant flowing from the indoor heat exchanger to the outdoor heat exchanger to the compressor in a heating operation and supercools refrigerant flowing from the outdoor heat exchanger to the indoor heat exchanger in a cooling operation. The second injection module injects a portion of refrigerant flowing from the indoor heat exchanger to the outdoor heat exchanger to the compressor in the heating operation and injects refrigerant flowing from the outdoor heat exchanger to the indoor heat exchanger to the compressor in the cooling operation. | 10-16-2014 |
