PURPOSE: An apparatus for controlling a brine channel of an accumulator of an ice storage cooling system is provided to prevent deterioration of cooling and ice making efficiency by dividing an inside of the accumulator into a high temperature layer and a low temperature layer, and allowing only high temperature brine to flow in and out of the high temperature layer and only low temperature brine to flow in and out of the low temperature layer and not to be mixed with each other regardless of cooling and ice making. CONSTITUTION: A low temperature refrigerator forms a closed circuit with a cooling tower(121) and a coolant pump(122). A first brine circulation channel(130) connects between a low temperature tube and a high temperature tube of the low temperature refrigerator and an accumulator(110) to form a closed circuit. The first brine circulation channel has a brine pump placed thereon, and connected with a brine inlet tube(151) and a brine outlet tube(152) of a heat exchanger(150) having cold water introduced therein through a cold water inlet tube(153) and discharged through a cold water outlet tube(154). The first brine circulation channel and the low temperature tube of the accumulator are connected by a second brine circulation channel(3) with a second opening and closing valve(3A).
