A refrigerant distribution device of a multi air-conditioner is provided to reduce the loss of refrigerant in the event of refrigerant leakage or failure of the indoor unit and to reuse the refrigerant collected from the pipe when starting the air-conditioner. A refrigerant distribution device of a multi air-conditioner comprises one main pipe(130) which is extended from an outdoor unit(110) and in which refrigerant flows, a plurality of sub pipes(140) which are branched from the main pipe to respective indoor units(120) and in which refrigerant flows, a branch pipe which is installed on the position where the main and the sub pipes are branched, a pump which operates to inhale the refrigerant inside the main and sub pipes, and a refrigerant tank which stores the refrigerant inhaled by the pump. |
