PROBLEM TO BE SOLVED: To provide a system for high-freshness refrigeration which is simple and small in size and enables saving of an installation space and a manufacturing cost. SOLUTION: A cooling-humidifying part 10 and a chiller part 20 are constituted in a single air washer unit 1. The cooling-humidifying part 10 is equipped with an upper water tank 11, a water-air contact material 12, a lower water tank 13, a blower 14 and a shower part 15. The chiller part 20 is equipped with a compressor 21, an air-side heat exchanger 22, an expansion valve 23 and a water-side heat exchanger 24. A fitting hole 2a piercing the ceiling of a refrigerating chamber 2 having a wall surface formed of a panel of a heat insulating material is formed in the upper part of the chamber. The air washer unit 1 is inserted into the fitting hole 2a so that the cooling-humidifying part 10 is located in the refrigerating chamber 2 and that the chiller part 20 is disposed above the chamber 2.
