HELIOSYSTEM Russian patent published in 2015 - IPC F24J2/34 

FIELD: heating.

SUBSTANCE: heliosystem contains a liquid system 1 with transparent enclosure 2, filled with low boiling heating medium 3, and steam tank 4 with heat insulating cover 5 and heat-exchanger 6. Both tanks are connected by pipe 7 and overflow pipe 8 for steam and condensed liquid movement. Liquid tank contains a container 10 with phase-transition heat accumulating material made as rib heat-exchanger with increased surface of heat exchange out of the material having high specific thermal conductivity. The heat-exchanger 6 with supply 11 and reverse 12 pipelines is connected with 3-way valve 13 to heat-exchangers 14 and accumulator 15, and creates a second closed circuit with the same heating medium. Container with phase-transition heat accumulating material is made out of the material with high specific thermal conductivity, for example out of composite materials with high thermal conductivity. Container 10 design is such that contact surface of the heating medium is increased.

EFFECT: increased efficiency of heat transfer from the heat accumulating material to the heating medium upon absence of sun radiation and in reverse direction upon sun radiation presence.
