PURPOSE: A cooling control method is provided to appropriately cool an object because a cooling device uses a cooling history or indoor temperature to control cooling without using a cold water temperature sensor. CONSTITUTION: A cooling control method is as follows. In case that a cooling history doesn't exist, a cooling degree is decided by using a temperature of a place where the object is arranged, and an object is cooled(S20). In case that the cooling exists, the cooling degree is decided by using the cooling history, and the object is cooled(S30).
