Abstract: Disclosed herein are an air conditioner and a method of controlling the same. In a selective cooling/heating multi-system air conditioner, refrigerant flow noise is minimized when cooling operations are changed to heating operations and vice versa. The method of controlling the air conditioner comprises opening one of cooling (164a-d) and heating (162a-d) valves so as to perform one of cooling and heating operations. The cooling valve is opened when at least one indoor unit is operated at a cooling mode, and the heating valve is opened when the indoor unit is operated at a heating mode. The method of controlling the air conditioner further comprises closing the cooling and heating valves, and, after a predetermined period of time elapses, opening the other of the cooling and heating valves so as to bring about a change between the cooling and heating operations of the indoor unit.

A high-pressure gas branch pipe(37) is branched between compressors(22) and outdoor heat exchangers(24) for moving a part of refrigerant discharged from the compressors in the cooling and heating mixed operation into the vapor-liquid mixing element as liquid refrigerant through the outdoor heat exchangers and the decompression element of the outdoor unit, and moving the rest of the refrigerant into the vapor-liquid mixing element as high-pressure gas refrigerant through the high-pressure gas branch pipe. The high-pressure gas refrigerant is mixed with the liquid refrigerant to be moved into a cooling and heating switching device as two-phase refrigerant. The cooling and heating switching device forms a vapor-liquid separator at the liquid pipe for flowing liquid refrigerant into the indoor units performing cooling operation and flowing high-pressure refrigerant into the indoor units performing heating operation.
