20110174002 | REFRIGERANT SYSTEM AND METHOD FOR CONTROLLING THE SAME - A refrigerant system includes an outdoor unit and a plurality of indoor units. The outdoor unit has a compressor and a plurality of heat exchangers and each indoor unit has a heat exchanger. A detector detects pressures at an inflow side and a discharge side of the compressor, and a controller controls a direction of refrigerant flow for the heat exchangers of the outdoor unit. This may involve changing the refrigerant flow direction for at least one of the heat exchanger of the outdoor unit based on the detected pressures. | 07-21-2011 |
20110192181 | REFRIGERANT SYSTEM - A refrigerant system is provided. The refrigerant system may use an electronic expansion valve that electronically controls an opening degree thereof, as a high-pressure valve and a low-pressure valve to selectively block a high-pressure branch valve and a low-pressure branch valve. Accordingly, noise transmitted to an interior space may be minimized when the operation mode of the refrigerant system is switched. In addition, the structure of the refrigerant system may be simplified. | 08-11-2011 |
20110192183 | REFRIGERANT SYSTEM - Provided is a refrigerant system including a high-pressure bypass tube guiding a refrigerant of a high-pressure tube to flow into an indoor unit tube by bypassing a high-pressure valve. Thus, impact and noise that may be generated when an operation mode of an indoor unit is switched to a heating mode may be minimized. | 08-11-2011 |
20120073311 | REFRIGERANT SYSTEM AND METHOD FOR CONTROLLING THE SAME - A refrigerant system and a method for controlling the same are provided. A refrigerant system includes: an outdoor heat exchanger disposed in an operating loop of the refrigerant system and configured to perform a heat exchange between outdoor air and a refrigerant; a compressor disposed in the operating loop and configured to compress the refrigerant; an indoor heat exchanger disposed in the operating loop and configured to perform a heat exchange between indoor air and the refrigerant; an expander disposed in the operating loop and configured to expand the refrigerant; a refrigerant storage connected to the operating loop and configured to receive and store the refrigerant from and discharge the refrigerant to the operating loop; and a refrigerant storage controller configured to control a total amount of refrigerant in the operating loop based on an indoor air conditioning load and an amount of the stored refrigerant. | 03-29-2012 |
20120073313 | REFIGERANT SYSTEM AND A CONTROL METHOD THE SAME - The present invention relates to the refrigerant system in which the refrigerant amount stored in the accumulator may be adjusted by the super cooling adjustment unit according to the indoor conditioning load. Therefore, according to the present invention, the flow refrigerant amount on the refrigerant cycle may be optimally adjusted according to the indoor conditioning load, and there is an advantage that the operation efficiency may be more improved. | 03-29-2012 |
20130081424 | SCROLL COMPRESSOR AND AIR CONDITIONER INCLUDING THE SAME - Provided is a scroll compressor, which includes a stationary scroll including a first wrap, an orbiting scroll including a second wrap, wherein the orbiting scroll and the stationary scroll are disposed to have a phase difference therebetween, and a compression room is formed between the first and second wraps, an inflow part for introducing refrigerant into the compression room, a first introduction part disposed on a side portion of the stationary scroll to inject refrigerant into the compression room, and a second introduction part disposed on another side portion of the stationary scroll to inject refrigerant into the compression room. Pressure of the refrigerant injected by the second introduction part is different from that of refrigerant introduced into the first introduction part. The second wrap moves while the orbiting scroll orbits, and opens the first introduction part before the introduction of the refrigerant through the inflow part is completed. | 04-04-2013 |
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 |
20130298582 | REFRIGERANT SYSTEM AND A CONTROL METHOD THE SAME - A refrigerant system according to an embodiment of the disclosure includes a outdoor heat exchanger performing heat exchange between outdoor air and a refrigerant; a compressor compressing the refrigerant; an indoor heat exchanger performing heat exchange between indoor air and the refrigerant; an expansion portion expanding the refrigerant; and a refrigerant pipe connecting the outdoor heat exchanger, the compressor, the indoor heat exchanger and the expansion portion to form a refrigerant cycle, wherein the outdoor heat exchanger includes a refrigerant storage portion storing the refrigerant to control flowing refrigerant amount on the refrigerant cycle. | 11-14-2013 |
