HEAT-AND-COLD SUPPLY SYSTEM Russian patent published in 2005 - IPC

FIELD: heating and cooling systems.

SUBSTANCE: invention relates to heating of buildings and cooling of refrigerating chambers using high-pressure gases, for instance, natural gas. Proposed system contains vortex tube installed on gas main line after preliminary gas preparation plant, heating system and hot-water supply system with heating devices, heat exchanger and pump, and also cold supply system with coil in refrigerating chamber and pump. All components of systems are coupled by straight and back pipelines. Coils interconnected by jumper pipe are arranged from outer of vortex chamber and heated gas outlet pipeline of vortex tube. Segments displaced relative to each other through one turn of coil mounted on said segments are arranged on inner surface of pipeline of heated gas outlet at opposite sides. Coil is connected with outer coils and straight pipeline of heating and hot-water supply systems provided with controller connected electrically by impulse lines with inner and outer air temperature sensors and actuating mechanism rigidly coupled through shaft with control element installed at outlet of heated gas of vortex tube. Coil placed inside cooled gas outlet branch pipe communicates hydraulically with pump and, through straight pipe line, with coil of refrigerating chamber.

EFFECT: improved environment protection.
