Embodiment 1

[0090] As an improvement, the central controller 26 automatically controls the opening and closing of the valves 22 and 24 according to the detected temperature of the heat storage material and the temperature of the water entering the heat storage.

[0091] Preferably, valve 24 is open and valve 22 is closed during normal operation.

[0092] If the temperature of the heat storage material is higher than the temperature of the water entering the heat accumulator, the central controller 26 automatically controls the valve 24 to close and the valve 21 to open simultaneously. Ensure that water does not enter the heat accumulator, because if water enters the heat accumulator 16 at this time, it will not only fail to have the effect of heat storage, but will transfer the heat in the heat storage material to the water, thereby reducing the heat storage effect. Energy can thus be saved by this measure.

[0093] If the temperature of the water detected by the bypass pipeline temperat...

Embodiment 2

[0100] As an improvement, the central controller 26 automatically controls the closing of the valves 20, 22, 25 according to the detected temperature of the inlet pipe of the heat accumulator 16, the temperature in the water tank 8 and the temperature of the bypass pipeline.

[0101] If the temperature of the heat accumulator inlet pipe detected by the central controller 26 is lower than the temperature of the heat storage material of the heat accumulator, the central controller 26 automatically closes the valve 24 and the valve 20 and opens the valve 22 . Opening the valve 22 can ensure that the water between the valves 20 and 24 can be circulated to the water tank through the bypass pipeline for heating, and the water between the valves 22 and 24 that does not meet the temperature requirement can be drained simultaneously. The water in the water tank 8 continues to be heated by solar energy. When the water temperature in the water tank 8 exceeds a certain value of the tempera...

Embodiment 3

[0111] Embodiment 3 is a further improvement of Embodiment 2.

[0112] If the temperature of the heat accumulator inlet pipe detected by the central controller 26 is lower than the temperature of the heat storage material of the heat accumulator, the central controller 26 automatically closes the valve 24 and the valve 20 and opens the valve 22 . Opening the valve 22 ensures that the water located between the valves 20 and 24 can be circulated through the bypass line to the water tank for further heating. The water in the water tank 8 continues to be heated by solar energy. When the temperature of the water in the water tank 8 exceeds a certain value of the heat storage material temperature, preferably more than 10 degrees Celsius, the valve 20 is opened, and the water flows through the bypass pipeline. If the bypass pipeline sensor When the water temperature detected by 21 exceeds a certain degree of the heat storage material, for example, 5 degrees Celsius, the bypass pipeli...

Abstract

The invention provides a solar heat accumulation system. The system comprises a heat collector and a heat accumulator; a heat accumulator pipeline valve and a heat accumulator pipeline temperature sensor are arranged on a heat accumulator pipeline, while a bypass pipeline valve and a bypass pipeline temperature sensor are arranged on a bypass pipeline; a central controller automatically controls opening and closing of the heat accumulator pipeline valve and the bypass pipeline valve according to a detected temperature of a heat accumulation material and a temperature of water entering the heat accumulator. The solar heat accumulation system meets the requirements of intelligent heat accumulation by intelligently controlling the valves of the heat accumulator pipeline and the bypass pipeline.

Description

technical field [0001] The invention belongs to the field of solar energy, in particular to a solar heat storage 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 received by the earth's sur...
