POWER SUPPLY INSTALLATION FOR RURAL CONSUMERS USING NATURAL HEAT AND COLD SOURCES Russian patent published in 2004 - IPC

FIELD: electrical engineering; power supplies. SUBSTANCE: heat-insulated heat storage of power installation which is in thermal contact with combustion chamber is vacuum-tight structure; its top part communicates through valve and control valve with water supply system and with pipes disposed above condenser; bottom part of heat- insulated heat storage communicates through pump with inlet and outlet parts of solar collector; condenser is also vacuum-tight structure and is in thermal contact with cold storage, its top part being in communication with vacuum pump and through the latter, with atmosphere; electrical expander unit is placed in pipe running from heat-insulated heat storage to intermediate inner part of condenser; cold storage communicates through pipeline with pump, water supply, and water users. EFFECT: enhanced level of power generated, reduced specific cost of generated electrical energy. 3 cl, 1 dwg
