FIELD: dehumidification of compressed gas flow. SUBSTANCE: proposed method includes cooling and separating condensed moisture in moisture separator at delivery of two flows of compressed gas from different sources. Preliminary cooling of one flow is performed in the course of its expansion in vortex tube and cooling of other flow is effected at mixing with first cooled flow. Energy separation chamber of vortex tube is cooled by flow escaping from moisture separator, after which this flow is delivered to consumer. EFFECT: reduced dimensions of heat exchanger; possibility of excluding heat exchanger whose function is performed by vortex tube. 4 cl, 2 dwg
