FIELD: compression machines, plants or systems using vortex effect.
SUBSTANCE: dehumidifier operation method involves precooling part of flow due to its expansion in expansion means, namely in gas-flow throttle or in vortex tube and cooling the main gas flow by precooled flow part; separating condensed moisture in moisture separator; cooling gas flow supplied to expansion means inlet by condensed moisture. Dehumidifier comprises high-pressure gas source, expansion means and moisture separator having drain pipe connected to cooling chamber of heat-exchanger which cools gaseous flow at expansion means inlet.
EFFECT: reduced power consumption.
