COMPRESSED AIR DEHUMIDIFICATION SYSTEM AND METHOD FOR DEHUMIDIFYING COMPRESSED AIR

摘要

PROBLEM TO BE SOLVED: To improve the efficiency for cooling compressed air in a heat exchanger while lowering the burden of a refrigerating cycle.;SOLUTION: The compressed air dehumidifying system comprises a refrigerating cycle 3 having a compressor 31, a condenser 32, an expansion valve 33, and an evaporator 34, and a secondary cooling part 22 that is provided with the evaporator 34 and causes alternative heat exchange between compressed air to be dehumidified and a cooling medium within the evaporator 34 to cool the compressed air, so as to be able to dehumidify the compressed air to remove moisture therefrom. The system further comprises a second heat exchange part (a cooler 7 and a condenser 32) at a previously specified position (in this example, the position of the condenser 32) between a cooling medium outlet of the compressor 31 and an expansion valve 33 in a cooling medium flow path through which a cooling medium is circulated within the refrigerating cycle 3 for cooling the cooling medium by causing alternative heat exchange between drain water W generated within a compressed air supply system 1 comprising the compressed air dehumidifying system 1A and the cooling medium within the refrigerating cycle 3, wherein the second heat exchange part comprises an expansion valve 6 for insulation and expansion of drain water W.;COPYRIGHT: (C)2012,JPO&INPIT
