PROBLEM TO BE SOLVED: To provide a cooling device capable of cooling water and air at the same time. SOLUTION: The cooling device comprises a compressor 10; an evaporator 20; an expansion valve 24; a compressor protecting means 30 provided in a circulating line connected to the compressor 10 from the evaporator, to protect the compressor from a liquid refrigerant and/or a high pressure gas refrigerant flowing out of the evaporator; a water sprinkling means 42 for sprinkling water on the surface of the evaporator; a water cooling mechanism 40 disposed below the evaporator and having a cold water tank 44 for holding water sprinkled by the water sprinkling means, and a water circulating means 46 for circulating water held in the cold water tank to the water sprinkling means; and an air circulating means 50 for circulating air in a closed space so as to be blasted toward the surface of the evaporator. The water sprinkled on the surface of the evaporator by the water sprinkling means is cooled by the evaporator to drip into the cold water tank, and at the same time, the air blasted toward the surface of the evaporator by the air circulating means is cooled by the evaporator and circulated in the closed space to cool the water and air in the closed space.
