HOT WATER SUPPLY SUN POWER PLANT Russian patent published in 2006 - IPC F24D15/00 F24D15/02 

FIELD: energy transformation.

SUBSTANCE: sun power plant intends for conversing solar energy to thermal energy for using thermal energy for domestic appliances. Hot water supply sun power plant has at least one solar battery made of thermal collectors in form heat-insulated flat box-shaped cases. Top flat light-transparent panels are disposed in perpendicular to direction of sun light. Light-transparent panels are disposed above membranes-absorbers which absorb solar radiation. Membranes-absorbers are provided with temperature transducers. Membranes-absorbers have parallel lateral metal pipes for liquid heat carrier. Pipes are connected together in any membrane-absorber by longitudinal tubular collectors. Collectors are connected together by branches in series through drive stop valves which are connected to pipeline of water discharge of warmed liquid heat carrier which is connected with top area of heat-accumulating container. Lower area of container is connected with longitudinal tubular collector of membrane-absorber of one of end heat collector by means pipeline for supplying cooled liquid heat carrier through circulation pump. Heat water supply and heating system heat exchangers are disposed at top area of heat-collecting container one above another. Heat exchangers are connected with central heating system pipeline and with pipeline for supplying warmed running water. Program electron unit of the plant is connected with temperature transducers of membranes-absorbers, which unit controls operation of thermal transducers, circulation pump electric motor and drives of stop valves. Sun power plant is provided with heat-proof heat-accumulating members that are disposed uniformly in lower area of heat-accumulating container. Heat-accumulating members are filled with liquid having positive solidification temperature. Program electron unit is provided with mechanisms for tracking perpendicularity of solar energy to surface of top light-transparent panels of thermal collectors. Heat-insulated flat box-shaped cases of collectors are made for rotation around horizontal axes disposed at two mutually perpendicular vertical planes. Any membrane-absorber is made in form of thin-walled metal plate with gofers which embrace parallel lateral metal pipes for liquid heat carrier. Space V of heat-insulated working cavity of heat-accumulating container exceeds total space V_tot of cavities of membranes-absorbers of heat collectors for liquid heat carrier, space V₁ of hot water heat exchanger for domestic appliances, space V₂ of heating system heat exchanger and total space V_h-am of heat-collecting member for 50-400, 100-120, 20-30 and 10-20 times correspondingly. Total area S_tot of external surfaces of the heat exchangers is 3-8 times larger than areas S_m of top surfaces of rigid membranes-absorbers. Solidification temperature T of liquid which fills heat-proof heat-accumulating members equals to 35-60⁰C.

EFFECT: improved efficiency of heating process; lower speed of heat carrier cooling.
