METHOD OF CONTROLLING COOLING DEVICE

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.

1. A method of controlling a cooling device cooling a heat source,
said cooling device including
a compressor for circulating a coolant,a heat exchanger performing heat exchange between said coolant and outside air,a cooling unit cooling said heat source using said coolant,a liquid storage container storing said coolant in a liquid state condensed by said heat exchanger,a first passage through which said coolant discharged from said compressor flows into said cooling unit through said heat exchanger and said liquid storage container,a second passage through which said coolant is circulated between said heat exchanger and said cooling unit without applying motive power when said compressor is stopped, anda switching valve switching between communication of said first passage and communication of said second passage, said method comprising the steps of: blocking said first passage from a state of allowing communication of said first passage and blocking said second passage; after said step of blocking said first passage increasing an amount of said coolant in the liquid state stored in said liquid storage container; and after said step of increasing an amount of said coolant, allowing communication of said second passage while maintaining blocking of said first passage.
