    摘要： A method of controlling a cooling device capable of stably cooling a heat source is provided. A cooling device includes a first passage through which a coolant discharged from a compressor flows into a cooling unit for cooling EV equipment; a second passage through which the coolant is circulated between a heat exchanger and the cooling unit; a switching valve switching communication of the first passage and communication of the second passage; and a liquid storage container storing a liquid coolant condensed in the heat exchanger. The control method includes the steps of: increasing an amount of the liquid coolant stored in the liquid storage container; and switching the switching valve so as to block the first passage and allow communication of the second passage.
