HOT-WATER SUPPLY EQUIPMENT Russian patent published in 2004 - IPC

FIELD: combined hot-water supply equipment utilizing solar and wind energy. SUBSTANCE: hot-water supply equipment includes sun collector, three-section tank- accumulator which upper section houses additional heater electrically coupled to wind-power set, middle section houses heater electrically coupled to wind-power set, heat exchanger which inlet is connected to outlet of sun collector via three-way valve and which outlet is linked to inlet of additional heat exchanger located in lower section of tank-accumulator. Outlet of additional heat exchanger is coupled to inlet of sun collector. Inlet of additional heat exchanger is linked by means of lintel to three-way valve. Equipment also has pump to transfer water from upper section of tank-accumulator into its middle section and pump to transfer water from lower section of tank-accumulator into its middle (or upper) section through three-way valve. EFFECT: enhanced reliability of hot-water supply and efficiency of conversion of solar and wind energy to thermal energy. 1 dwg
