Embodiment 1

[0091] As an improvement, a temperature sensor is provided in the water tank 8 for measuring the temperature of the water in the water tank 8 . The inlet pipe 18 and the outlet pipe 17 of the water tank 8 are provided with an inlet pipe valve 22 and an outlet pipe valve 20 respectively, and the temperature sensor, the inlet pipe valve 22 and the outlet pipe valve 20 are connected with the central controller 21 for data. The central controller 21 controls the opening and closing and opening degree of the inlet pipe valve 22 and the outlet pipe valve 20 according to the temperature measured by the temperature sensor.

[0092] If the temperature of the water in the water tank 8 measured by the temperature sensor is lower than the lower limit value, then the central controller 21 controls the valves 20 and 22 to close automatically, thereby ensuring that the water in the water tank 8 continues to heat up; When the temperature exceeds the upper limit, the central controller 21 cont...

Embodiment 2

[0099] As an improvement, the central controller 21 ensures that the outlet water temperature in the water tank reaches a constant value by controlling the openings of the valves 20 and 22 . That is, the temperature of the outlet water of the water tank 8 is adjusted by adjusting the flow rate entering the water tank 8 and leaving the water tank 8 .

[0100] An outlet pipe temperature sensor 19 is arranged on the outlet pipeline 17 of the water tank, and the outlet temperature sensor 19 is connected with the data of the central controller 21, and the central controller 21 controls the inlet pipe valve 22 and the outlet pipe valve according to the temperature measured by the temperature sensor 19 20 opening and closing and the size of the opening.

[0101] If the temperature of the water in the outlet pipe 19 measured by the temperature sensor 19 is lower than the lower limit value, the central controller 21 controls the opening of the valve 20 to increase, reducing the opening...

Embodiment 3

[0108] As a further improvement of the second embodiment, the opening and closing of the valves 20 and 22 are controlled by measuring the temperature of the water in the water tank 8 .

[0109] If the temperature of the water in the water tank 8 measured by the temperature sensor 19 is lower than the lower limit value, the central controller 21 controls the opening of the valve 20 to increase, and reduces the opening of the valve 22, so that the water entering the water tank 8 decreases, leaving The water in the water tank 8 increases, thereby reducing the amount of water in the water tank 8 . The temperature of the water in the water tank 8 is increased by reducing the amount of water, thereby increasing the outlet temperature of the water tank 8 . On the contrary, if the temperature of the water in the water tank 8 measured by the temperature sensor 19 is higher than the upper limit value, then the central controller 21 controls the opening of the valve 20 to decrease, and i...

Abstract

The invention provides a solar heat collector system, the system includes a heat collector, the heat collector includes a heat collecting tube and a water tank, the heat collecting tube includes a heat absorbing end and a heat releasing end, and the heat releasing end is provided with In the water tank; a water level gauge is set in the water tank, an inlet pipe valve and an outlet pipe valve are respectively arranged on the inlet pipe and the outlet pipe of the water tank, and the water level gauge, the inlet pipe valve and the outlet pipe valve are connected with the data of the central controller; The central controller controls the opening of the inlet pipe valve and the outlet pipe valve according to the water level measured by the water level gauge. The invention automatically controls the water level in the water tank to prevent the water level from being too high or too low, thereby improving the intellectualization of the use of the heat collector.

Description

technical field [0001] The invention belongs to the field of solar energy, in particular to an intelligently controlled solar heat collector system. Background technique [0002] With the rapid development of modern society and economy, the human demand for energy is increasing. However, the reserves of traditional energy such as coal, oil, and natural gas continue to decrease and become increasingly scarce, resulting in rising prices. At the same time, the environmental pollution caused by conventional fossil fuels is also becoming more and more serious. These greatly limit the development of society and the improvement of human life quality. . Energy issues have become one of the most prominent issues in the contemporary world. Therefore, seeking new energy sources, especially non-polluting clean energy sources has become a research hotspot. [0003] Solar energy is an inexhaustible clean energy with a huge amount of resources. The total amount of solar radiation energy...
