<p>PROBLEM TO BE SOLVED: To provide a compressed air cooling and dehumidifying device in which cooling power and capacity heat exchangers is carefully regulated in a wide range in accordance with a change in the flow rate and temperature of compressed air. SOLUTION: Discharge branch paths 130 for compressed air discharged to a discharge path 140 from in tanks 10 of two dehumidifiers 100 each are provided with valves 112. In accordance with the feed quantity of compressed air fed to the two dehumidifiers 100, by regulating means 160, the valves 112 are regulated to any of a closed state, a semi-closed state, and a totally closed state. And the total of the opening degrees of the discharge branch paths 130 is regulated to any of 1/4, 2/4, 3/4, and 4/4. And at the same time, according to the opening degrees of the discharge branch, paths 130, by the regulating means 160, cooling power of two evaporators 42 of the two dehumidifiers 100 is set to an ON state or a OFF state. In accordance with the feed quantity of compressed air fed to the two dehumidifiers 100, cooling power of heat exchangers 30 of the two dehumidifiers 100 is regulated.</p> |
