COOLING DEVICE

Abstract:

A cooling device includes a refrigerant flow path provided in a propulsion system of a ship; an electric pump configured to cause a refrigerant or a cleaning medium to flow through the refrigerant flow path; and a control unit configured to control operations of the propulsion system and the electric pump. The control unit executes each of a plurality of operating modes including a first operating mode (normal operating mode) which drives the propulsion system and the electric pump and causes the refrigerant to flow through the refrigerant flow path, and a second operating mode (maintenance mode) which drives the electric pump without driving the propulsion system and causes the cleaning medium to flow through the refrigerant flow path.
