PROBLEM TO BE SOLVED: To prevent the growing of frost by increasing an air flow speed of the air flowing into an evaporator, while preventing the enlargement of an air blower. SOLUTION: The evaporator 13 is mounted at both of a suction side and a discharge side of the air blower 17. Whereby both of the air sucked to the air blower 17 and the air discharged from the air blower 17 are sent to the evaporator 13 and the collective frost formation areas for intentionally collecting the frost particles are formed at two parts of a rear edge part 134 of the evaporator 13 mounted at the suction side of the blower 17 and a rear edge part 135 of the evaporator 13 mounted at the discharge side of the air blower 17. As the collective frost formation areas are dispersed to two parts, a growing speed of the frost in the collective frost formation areas can be reduced to be approximately half of a conventional one. As the wind speed can be easily kept at more than 3 m/sec without excessively increasing the air blowing performance, the wind speed of the air flowing into the evaporator can be increased and the growing of the frost can be prevented, while preventing the enlargement of the air blower.
