ABSTRACT:
Disclosed is a cold-air generating device which comprises a first refrigerating system 15 including a first evaporator 1 and a compressor 4 and adapted to cool air to such a degree that the water contained therein will not become frozen, and a second refrigerating system 26 including a second evaporator 2 and a compressor 16 and adapted to further refrigerate the air dehumidified and cooled while passing through the first evaporator 1 down to a temperature below freezing point. Air inlets 27 and 28 may be provided in the upper sections of the first and second evaporators 1 and 2, respectively, so that a downward airflow will be generated therein, the respective lower sections of the first and second evaporators 1 and 2 being connected to each other through a drain pan 3. Furthermore, gauze 29 may be provided on that side of the second evaporator 2 which is connected to the first evaporator 1.
