Example Embodiment

[0098] 1. Example One

[0099] 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 respectively provided with an inlet pipe valve 22 and an outlet pipe valve 20. The temperature sensor, the inlet pipe valve 22 and the outlet pipe valve 20 are in data connection with the central controller 21. The central controller 21 controls the opening and closing of the inlet pipe valve 22 and the outlet pipe valve 20 and the size of the opening according to the temperature measured by the temperature sensor.

[0100] If the temperature of the water in the water tank 8 measured by the temperature sensor is lower than the lower limit value, the central controller 21 controls the valves 20 and 22 to automatically close, thereby ensuring that the water in the water tank 8 continues to heat up; if the measured water in the water tank 8 If the temperat...

Example Embodiment

[0106] 2. Example two

[0107] As an improvement, the central controller 21 controls the opening of the valves 20 and 22 to ensure that the temperature of the outlet water in the water tank reaches a constant value. That is, the temperature of the outlet water of the water tank 8 is adjusted by adjusting the flow rate into and out of the water tank 8.

[0108] An outlet pipe temperature sensor 19 is provided on the water tank outlet pipeline 17, and the outlet temperature sensor 19 is in data connection with the central controller 21. 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.

[0109] 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 and decrease the opening of the valve 2...

Example Embodiment

[0115] 3. Example Three

[0116] 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.

[0117] 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 decrease the opening of the valve 22, so that the water entering the water tank 8 is reduced and leaving The water in the water tank 8 increases, so that the amount of water in the water tank 8 decreases. 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, the central controller 21 controls the opening of the valve 20...

Abstract

The invention provides an intelligent control method for a solar energy system. A solar heat collector system comprises a heat collector, wherein the heat collector comprises a heat collecting pipe and a water tank; the heat collecting pipe comprises a heat absorbing end and a heat releasing end, and the heat releasing end is arranged in the water tank; a water level meter is arranged in the water tank, and an outlet pipe temperature sensor is arranged on an outlet pipeline of the water tank; an inlet pipe valve and an outlet pipe valve are respectively arranged on an inlet pipe and an outlet pipe of the water tank, and the water level meter, the temperature sensor, the inlet pipe valve and the outlet pipe valve are in data connection with a central controller; the central controller controls the size of the opening degree of the inlet pipe valve and the outlet pipe valve according to the temperature measured by the temperature sensor and the water level measured by the water level meter. The method automatically controls multiple parameters of the solar energy system, realizes intelligent control for the solar water temperature, and therefore improves the using intelligentization of the solar energy system.

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...
