SOLAR PLANT AND METHOD OF ITS OPERATION Russian patent published in 2010 - IPC F24J2/42 

FIELD: power engineering.

SUBSTANCE: solar plant comprises the following components included in the main circulation circuit - solar collector, providing for heating of antifreeze circulating through it, accumulator tank that accumulates thermal energy, heat exchanger inbuilt into accumulator tank, to transfer heat from antifreeze to water for hot water supply needs, and also heat consumer and system of automatic control. Solar collector is capable of heating air circulating through it, besides there are air ducts provided in plant for air motion, and double-stage heat exchanger for additional heating of air, connected by the first stage, through three-stroke valve, to the main circulating circuit, and by the second stage - through additional circuit to accumulator tank. Method for operation of solar plant includes conversion of energy of electromagnet solar radiation to heat two types of coolants (antifreeze and air), circulation of antifreeze along the main circulating circuit, transfer of heat from antifreeze to water for hot water supply needs in surface heat exchanger installed in accumulator tank, accumulation of thermal energy in accumulator tank and transfer of thermal energy to consumer in the form of water for needs of hot water supply and air for needs of air heating, besides, air for needs of air heating may be additionally heated in double-stage heat exchanger by heat of antifreeze and/or heat accumulated in accumulator tank, by means of additional circulating circuit.

EFFECT: increased efficiency of solar plant operation.
