PURPOSE: A bypass unit for a multi type air conditioner system is provided to prevent the staying of refrigerant and noise of a non-operating indoor unit while carrying out the cooling and heating operations simultaneously. CONSTITUTION: A bypass unit for a multi type air conditioner system includes a noise preventing unit(70) and a refrigerant-staying preventing unit(80). The noise preventing unit is provided to each indoor unit for blocking the introduction of refrigerant with respect to non-operating indoor units, thereby preventing the noise.
