The invention relates to solar technology, in particular, to combined plants for the conversion of solar energy into thermal energy, working in conjunction with traditional sources on organic topgive.

The purpose of the invention is to increase work efficiency by reducing operating costs.

The drawing shows a diagram of a solar heating system.

The solar heat supply system contains a source of unpurified water connected to a water treatment plant 2, an autonomous source of heat 3, connected to the supervisor, a solar collector 4 and a storage tank B connected to each other by direct and return pipelines 6, 7 with the formation of a closed heliocontrol, bchip 8, connected in parallel to the solar collector 4, supply pipe 9, connected to the storage tank 5, and control valves 10-24. The system further comprises a wind installation 25 connected to an autonomous heat source 3, and a backup heat source 26 connected in parallel to the solar collector 4 between the latter and the bypass 8; A chemical water treatment unit 2 and an autonomous heat source 3 are connected to the return line 7 of the gel circuit before the bypass 8, and the supply line 9 is connected by means of a jumper 27 to the reverse coarse side 7 after the storage tank 5.

The system is equipped with a pump 28. As sources 3, 26 can be used electroco (ly.

The solar heat supply system operates as follows.

Cold water from the unpurified water source 1 through the valve 18 enters the chemical water treatment unit 2, then into the autonomous heat source 3 fed from the wind turbine 25, where it is heated, and fed to the backup source 26 fed from the power system. In the presence of solar radiation, water enters the solar collector 4, and from there to the storage tank 5. After filling the latter, valve 18 closes, opens valves 21 and 23, starts pump 28, which circulates the coolant around the circuit: b c-battery torus 5. pump 27, source 3, 26 (in the presence of solar radiation - collector 4), storage tank 5. This cycle continues until the coolant reaches a temperature of 95 ° C. Upon its achievement, the valves 22 and 24 are opened, the valve 23 is closed, the redundant heat source is disconnected, the valves 10 and 11 are closed. The coolant is supplied to the consumer and through the valve 24 is returned to the system. The return water passes through the source 3, enters the collector 4 (in the presence of solar radiation), is heated and supplied to the storage tank 5. In the absence of solar radiation, the valves 12 and 13 are closed, the valve 14 is opened; the heat carrier from the heat source 3 passes through the valve 14 and enters the storage tank 5. This cycle continues until the minimum load in the electrical network is reached, after which the valves 10 and 11 open, the valve 14 closes. The backup heat source 26 is activated, the heat carrier is heated and enters the tank-battery 5. When the temperature reaches 95 ° C, the source 26 is turned off. valve 14 is opened, and valves 10, 11 are closed. The cycle continues through an autonomous heat source 3, in the presence of solar radiation through a collector 4, if it is not present, through a valve 14. The capacity of the storage tank 5 is calculated based on the need to keep the temperature of the coolant not lower than 60 ° C for 24 hours. and other parameter values.

In the case of excess time in the absence of sun and wind, the program of work of the complex provides for the extraordinary inclusion of a backup heat source 26, which provides heating of the coolant to the required temperature.

The invention saves material and energy resources due to the use of renewable energy sources for heating the heat transfer medium, and when the electric boiler is operating from the network, it equalizes the amplitude of the load oscillations in the electrical system with an increase in the cosine p.
