Abstract
an ice making system includes a tank that stores a medium to be cooled, an ice making machine that cools the medium and makes ice, a pump that circulates the medium between the tank and the ice making machine, a de-icing mechanism that heats the medium and melts the ice in the ice making machine, and a control device that controls operations of the ice making machine, the pump, and the de-icing mechanism. The ice making machine includes a cooling chamber that cools the medium, an inflow port through which the medium flows into the cooling chamber, and a discharge port through which the medium is discharged from the cooling chamber. The control device activates the de-icing mechanism when a pressure difference between a pressure of the medium at the inflow port and a pressure of the medium at the discharge port exceeds a predetermined value.
