Abstract

The invention makes it possible to increase the efficiency of using solar energy. The solar collector 5 has inlet and outlet nozzles 6, 7, the first of which is connected to the annular cavity 4 of the high-speed heat exchanger (T) 3, and the second is connected to the annular cavity 8 T I of raw water. The intertube cavity 8 T 1, in turn, communicates with the tube space of the high-speed T 3. The storage tank is connected to the inter-tube cavity 4 T 3, from where water is heated into the tank. The chemical water treatment unit 2 communicates with the tubular spaces T 1.3 for the treatment of the source water, then flows into the collector 5. The invention provides efficiency and. temperature regime collector. 1 il.

The invention relates to solar technology, in particular to solar heating systems.

The purpose of the invention is to increase the efficiency of solar energy use.

The drawing shows a schematic diagram of the heliosystem, 1 The heliosystem contains sequentially installed shell-and-tube heat exchanger I raw water, block 2 chemical water purification, shell-and-tube speed heat exchanger 3 associated with its intertubular cavity 4 tank accumulator 15 il the torus and the solar collector 5, which have outlet and inlet branch pipes 6 and J7, the latter of which is connected to the annular cavity 8 of the heat exchanger 11 of raw water, the pipe cavities I of the heat exchangers I and 3 are connected to the water cleaning unit 2. The output patru-side 6 of the solar collector 5 is connected to the annular cavity 4 of the speed-heat exchanger 3, the pipe space of the latter is in communication with the inter- I pipe cavity 8 of the heat exchanger 1; raw water. The heliosystem contains a three-way valve 9 and valves 10-13. Heliosystem works as follows;

In the morning hours, with sufficient intensity of solar radiation, shutters 12 and 13 are closed; chivakchie work at night, when: this water in the collector 5 is heated i to the working temperature and after opening the valves 10 and P and turning the valve 9 to a position that provides 14673362

roar to the desired temperature of the raw water in the tube space of the heat exchanger I. The cooled treated water from the annular cavity 8 enters for heating into the collector 5, and then into the annular space 4, where it releases part of the heat in the tube space of the latter and goes to boiler storage tank.

With a decrease in the intensity of solar radiation, the valves Yu and 11 are closed, and the valve 9 is switched to a position that ensures the connection of the water cleaning unit 2 with the storage tank 20

rum, and water begins to circulate in a small circuit as follows. The source water enters the tube space of the heat exchanger 1, where it is heated by an external heat source, is cleaned in block 2, and sent to the storage tank.

Through the use of the circuit, the efficiency of the collector is improved, the temperature is improved and the operation of the solar system is simplified.
