PROBLEM TO BE SOLVED: To provide a cooling system capable of decreasing a rate of operation of a pump and improving the efficiency of an engine. SOLUTION: The cooling system (1) of the engine (2) includes a water jacket (6) formed within the engine (2), an accumulator (9) disposed on the upstream side of the water jacket (6), the pump (13) disposed on the upstream side of the pressure accumulator (9) so as to pressure-feed a refrigerant to the pressure accumulator and pressurize the inside of the accumulator, and a first electromagnetic valve (14a), a second electromagnetic valve (14b) and a third electromagnetic valve (14c) for opening/closing flow paths for the refrigerant supplied from the accumulator (9) to the water jacket (6).
