AUTONOMOUS HEATING AND HOT WATER SUPPLY SYSTEM WITH NATURAL HEAT-TRANSFER AGENT CIRCULATION AND METHOD OF WARMING WATER UP Russian patent published in 2006 - IPC F24D3/10 

FIELD: heat supply water systems.

SUBSTANCE: autonomous heating and hot water supply system with natural heat-transfer agent circulation combined with hot water supply has thermogenerator, surge tank which is used as well as capacitive heater and hot water tank-accumulator provided with float valve for keeping water level in it automatically and with control overflow branch pipe, main post which connects top point of water jacket of thermogenerator with bottom of surge tank. System also has supply pipe-line which connects lower part of side walls of surge tank with heat supply and hot water supply posts, heating devices connected with heat supply posts, shower grids and hot water cocks connected with hot water supply posts. Heat supply posts and hot water supply posts are connected at their lower points with back pipe-line which is connected with lower point of water jacket of thermogenerator and which forms united heat-transfer agent circulation circuit. Heat supply and hot water supply posts are provided with switch-off cocks at their top and lower points. Surge tank- heat accumulator is made in form of cylinder mounted in vertical and is provided with cold water supply tangential branch pipe mounted at top part of tank and with cold water removal tangential branch pipe mounted at its lower part. Supply and back pipe-lines are made in form of rectangular circled units and are connected with surge tank-accumulator and with thermogenerator correspondingly at geometric centers of rectangular circles through T-shaped pipe-lines. Any hot water supply post is connected with supply pipe-line of top pipe of arrangement of pipe-lines through intermediate tank-heat accumulator. Bottom of intermediate tank is disposed at least 100 mm higher than supply pipe-line at its output from surge tank-accumulator. Hot water preset temperature automatic up-keeping detector is mounted at output of surge tank. Method of water heating in autonomous hot water supply system and hot water supply with natural heat-transfer agent circulation is described correspondingly.

EFFECT: improved stability of circulation of heating water; improved stability of operation in case of unpredictable failure of water supply from pipe-line; prevention of hot water boiling in main post; higher intensity of mixing of hot and cold water in surge tank; simplified exploitation of system multistory buildings.
