SYSTEM OF HEAT SUPPLY AND HOT WATER SUPPLY BASED ON RENEWABLE ENERGY SOURCES Russian patent published in 2012 - IPC F24J2/42 F24J3/08 

FIELD: power engineering.

SUBSTANCE: system of heat supply and hot water supply based on renewable energy sources comprises a heat exchanger well for takeoff of low-potential heat of rocks, a heat pump, a peak power cinch and circuits of hot water supply and low-temperature floor heating, which are connected to each other by pipes with two pumps for circulation of coolants. The system is additionally equipped with a circuit having solar collectors and an accumulating tank. The circuit with solar collectors is operated as year-round and provides hot water to a consumer, and a unit of low-temperature floor heating with a heat pump and a heat exchanger well with depth of 100-200 m is put in operation only during the heating period. During the heating period on the background of continuous water circulation in the well, gradual cooling of rock around the well takes place. In summer period some hot water from the accumulating tank is sent to the well for complete recovery of temperature in rocks around the well.

EFFECT: higher thermodynamic efficiency and uninterrupted supply of heat energy to a consumer.
