Abstract:
A storage system comprising:a heat-insulating outer shell capable of insulating an inner space; an ice storage water tank capable of storing water therein disposed in an ice storage water tank disposing space provided in the inner space of the heat-insulating outer shell; a storage space for storing objects to be stored provided in the inner space of the heat-insulating outer shell; an outside-air inlet opening provided at a lower portion of the heat-insulating outer shell, the inlet opening capable of introducing outside air into the inner space; an inside-air outlet opening provided at an upper portion of the heat-insulating outer shell, the outlet opening capable of discharging inside air from the inner space of the heat-insulating outer shell to the outside; and an object entrance-exit opening provided at an upper portion of the heat-insulating outer shell for allowing entrance-exit of the objects to and from the storage space, wherein when the storage system is utilized in a cold weather environment, the outside-air inlet and inside-air outlet may be selectively opened to pass substantially sub-zero ambient air through the inner space to freeze the water that may be stored in the ice storage water tank.
