This autonomous heating system differs from the prototype by the presence of five interacting circuit heat-transfer fluid is automatically controlled units for monitoring and control parameters for the three major systems (main closed circulation loop, the hot heating circuit and consumers heating circuit).

System operation begins with the start of operation of small closed loop, through which run the entire system through bringing the heat transfer parameters to optimal values. Fed through the control unit 26 opens valves 3, and is opened and valves 18, 5, 6, 7, 9, 10, 12-15, 21, 16,17, and the tank is filled to the desired value 1, and a small and basic closed circulating coolant circuits. After filling of the tank circuit and coolant (water) comes closing valves 14, 15, 18, 3. From the heat generator 2 installed in tank 1, the coolant is circulated through the pipeline system shut-off valve 5, 6, 7, 9,10, 12 , 13, 16, 17, the electromagnet 11, a pumping group 8 and returns back to block heat generator 2 installed in tank 1.

When the temperature reached 60 ° C activated closed main flow circuit, with the open valves 14 and 15 are closed valves 16, 17 and 5.

The main closed circulation loop operates as follows: the coolant passes through the heat generator unit 1 2, a design feature which reduces the speed and pressure of the coolant, according to the known laws of thermodynamics, changes the mechanical energy of the fluid, which leads to an increase in temperature of the coolant. heat generator unit 2 is immersed in a tank 1 to the upper sealed lid, inside a colored paint with organosilicon t 150 ° C, and isolated from the outside heat-insulating material. The coolant circulates through the pipeline through the shut-off valves 14 and 15, falls on the entrance №1 19 plate heat exchanger, gives off heat the heated environment and through the exit 20 PT №1 by pipeline through the shut-off valve 21, 6, 7, gets to the input of the pumps 8, then through shut-off valve 9, 10, on the pressure pipe on which the electromagnet 11, the line of tension which are directed perpendicular to the movement of the coolant - to increase heat release (so-called "anomalous" heat). Further, through the shut-off valve 12, 13 is returned back to the coolant in the heat generator unit 2 is installed in the tank 1. This circuit is controlled via the control unit 22 according to the signals from the sensor 23.

The circuit between the plate heat exchangers included in the job when you do not need space heating and hot water to consumers is necessary. The circulation of the coolant along the contour between the plate heat exchangers is carried by pipelines connecting output 43 to the input of PT №1 №2 31 PT through the shut-off valve 39, the output 32 to the input of PT №2 №1 PT 44 through the circulation pump 34 and the shut-off valve 36, and the valves 37, 38, 40 is closed. Control of the parameters of the coolant in the circuit monitor and control unit 22 to the sensor readings 23, 24, 25.

DHW serves to heat the water going to the needs of the consumer, which is accumulated in the tank 1, where the heat generators mounted unit 2. The heated water, which goes to the needs of the consumer, is preheated via heat generators wall passes via line 18 through shut-off valve, a check valve 35 and a circulation pump 33 and fed to the input FET 29 №2, heated therein to a predetermined temperature is supplied by flow line 28. Water DHW consumer via a return conduit by hot water through a pipeline shut-off valve 4 is returned back to the tank 1.

serves as the control unit 26 via the water make-up water shutoff valve from the hole 3, the central water supply sources or other sources of water piped directly to the tank 1. When the minimum water level in the tank 1 to the control unit 26 is provided for regulating domestic hot water tank and the automatic replenishment 1 vodoukazatelnogo signal from the controlled device 27, stop valves 3 opens and closes valves 4. When filling the tank 1 to a certain level signal is input to the control unit 26 which commands the closing of valves 3 and 4. The opening of valves for the control parameters in the coolant this circuit unit is carried out monitoring and control 22 to sensor readings 23, 24, 25.

Circuit consumer heating system used to heat consumers involved in the cold period, and can be operated in different modes.

In normal mode, the coolant circulates on a contour of heating consumers, through the circulation pump 34 through line 36 through the shut-off valve reaches the entrance 44 TP №1, where warmed to a predetermined temperature through the exit 43 PT №1 by pipeline through the shut-off valve 40 is supplied to the feed heat supply line 28, where the convective heat giving consumers back on heating feedback line through the shut-off valve 38 to the input of the PT 31 №2, heats the water that goes to the needs of the domestic hot water, through the exit 32 PT №2 to the input of the circulation pump 34. In this case, valves 37, 39 closed, the circulation pump 41 is not running and can be turned on as needed (for more efficient heat transfer in the coldest period).

By lowering the temperature of the outer valve 40 is closed, the coolant through the check valve 42, circulating pump 41 enters the feed line 28, heat supply, where convective heat is giving consumers back on heating feedback line through the shut-off valve 38 to the input of the PT 31 №2, heats the water, extending the needs for domestic hot water, via the outlet 32 ​​supplied to the FET №2 circulation pump inlet 34 via line 36 through shut-off valve 44 reaches the input FET №1, warmed to a predetermined temperature, through the outlet 43 via conduit №1 PT reaches the entrance of the check valve 42. In this case, valves 37, 39 closed.

At night, or for other economic reasons possible closing of valves 36, 38, 39, 40 and the opening of valves 37, off the circulation pumps 33, 34 and the circulation pump 41.

Autonomous heating system operates automatically through the control unit 22. According to the signals of the sensors 23-25 ​​are installed on the main circuits of the system, coming on the electrical circuits in the control unit 22, switch on and off electrical devices included in the system.
