PROBLEM TO BE SOLVED: To prevent high pressure of a refrigerant circuit 100 to which adsorption heat exchangers 101, 102 are connected from excessively increasing and thereby preventing a compressor 103 from stopping, even when ambient temperature of an installation place of a dehumidification device 10 is high, in a dehumidification device using adsorption blocks 301, 302 together with the adsorption heat exchangers 101, 102.SOLUTION: A dehumidification system includes a changeover mechanism 200 that before activating a compressor 103 of a refrigerant circuit 100, performs precooling operation for flowing cooling air to adsorption blocks 301, 302 positioned on an upstream side to adsorption heat exchangers 101, 102 to be a condenser in activation of the compressor 103.SELECTED DRAWING: Figure 4 |
