PURPOSE: A refrigerant flow control apparatus is provided to supply refrigerant in an appropriate manner and improve evaporating capability of refrigerant by preventing the refrigerant from being fed to the evaporator of indoor unit which is not in operation. CONSTITUTION: A refrigerant flow control apparatus comprises first, second and third main refrigerant pipes(110,120,130) having ends connected to a condenser side circulation pipe(90) connected to a condenser(84) and the other ends connected to first, second and third evaporators(52,62,72), such that the refrigerant passed through a condenser(84) is fed to each evaporator; first, second and third capillary pipes(112,122,132) installed to first, second and third main refrigerant pipes, respectively, so as to reduce pressure of the refrigerant introduced into each of first, second and third main refrigerant pipes; and a refrigerant control unit for controlling the refrigerant passed through first, second and third capillary pipes to be fed only to the evaporator of indoor unit in operation.
