SOLAR SYSTEM Russian patent published in 2017 - IPC F24J2/42 

FIELD: heating system.

SUBSTANCE: solar system contains two hydraulic circuits with pipelines, a solar collector having a supply and discharge branch pipes, a heat storage tank with a heat exchanger connected by a three-way valve to form a second closed circuit. The first hydraulic circuit contains a heat-insulated container with a hinged cover-screen, a heat storage tank, a second hydraulic circuit contains a solar collector and a heat exchanger housed inside the heat storage tank. In the hydraulic system, respectively, circulating and vacuum pumps are introduced. The vacuum pump is embedded in the pipeline on the second circuit between the output branch pipe of solar collector and pipeline before entering the heat exchanger and the circulating pump is embedded in a direct pipeline of the first circuit to the entrance of the heat storage tank, whose exit is connected to the container input by reversed pipeline. The first input-output of the three-way valve is attached to the input branch pipe of the solar collector, to whose second input-output the output of heat exchanger is connected in parallel with the third input of the tapering device introduced into the system, the output of which is connected to the input of the three-way valve.

EFFECT: increasing the efficiency of using solar energy to maintain a favourable temperature of consumer in a wide temperature range of ambient air.
