Title:
COOLING DEVICE
Document Type and Number:
Japanese Patent JP2021127904
Kind Code:
A
Abstract:
To provide a cooling device that can control air with a temperature at which air is likely to contain moisture from flowing into a cooling space in defrosting a cooling evaporator.SOLUTION: A cooling device 100 includes: a compressor 10; a condenser 20; expansion parts 31-33; evaporators 41-43; blowers 51a-53a, 51b-53b for cooling the air sucked from a suction port 78 and sending the air to a blowing port 77 after cooling the air by causing the air to pass through the evaporators 41-43 at cooling; and a control unit 60 for performing such a control as raising the temperature of the evaporators 41-43 to a temperature higher than the temperature at cooling and changing a flow of the air supplied by the blowers 51a-53a, 51b-53b to an inverse direction at cooling to circulate the air through circulation paths 74-76 including the evaporators 41-43 and remove the frost from the evaporators 41-43 with wind power in defrosting the evaporators 41-43.SELECTED DRAWING: Figure 1
