CONTROL DEVICE FOR COOLING SYSTEM

A control device for a cooling system is provided. The cooling system includes a cooling path through which a heat medium flows in an order of a first unit and a second unit. The cooling system is configured to cool the first unit and the second unit. The control device includes a processor being configured to execute: a process of repeatedly detecting or estimating a temperature of the heat medium flowing out of the first unit at predetermined time intervals, a process of storing a plurality of pieces of temperature data of the temperature detected or estimated during an immediately preceding predetermined period as a data group including a predetermined number of pieces of data, and a process of estimating a temperature of the heat medium flowing into the second unit by finding a maximum value from the data group.
