Abstract (en)
Disclosed herein are a simultaneous cooling and heating type multi-system air conditioner and a method of controlling the same that can minimize noise generated when operation mode of each indoor unit is changed. The air conditioner includes a compressor, at least one indoor unit, a mode change unit having a cooling valve openable to perform a cooling operation of the indoor unit and a heating valve openable to perform a heating operation of the indoor unit, a refrigerant cycle to connect the compressor, the mode change unit, and the indoor unit, a hot gas bypass valve disposed between inlet and outlet sides of the compressor, and a controller to control the cooling valve to be turned off for a first predetermined time around the point of time when the hot gas bypass valve is turned on, when operation mode of the indoor unit is changed from cooling mode to heating mode, so as to minimize the difference between the pressure of a high-pressure section of the refrigerant cycle and the pressure of an outlet side of the indoor unit.
