FIELD: heat-power engineering; heat supply systems.
SUBSTANCE: proposed method includes delivery of heat-transfer agent to heat source-vortex tube for heating it followed by delivery of heat-transfer agent to consumer and return of its to heat source; heat-transfer agent delivered to consumer is divided in vortex tube into cold and hot flows via cold flow pipe line and hot flow pipe line, respectively. Heat from low-potential heat source is delivered to cold flow escaping from vortex tube.
EFFECT: enhanced economical efficiency due to utilization of low potential heat; enhanced ecological safety.
