The invention provides a liquid level difference descaling method for a heat collecting device. The method comprises the steps that an electric heater is arranged in a heat collecting tube box; the electric heater operates at night; a liquid level detection element is in data connection with a controller; the controller extracts liquid level data according to the time sequence; through comparison of the liquid level data in the adjacent time periods, the liquid level difference or the accumulation of the liquid level difference change is obtained; and the electric heater is controlled to stop heating or continue heating by the controller when the liquid level difference or the accumulation of the liquid level difference change is lower than a threshold value. According to the liquid level difference descaling method, the stable state of the fluid is judged according to the liquid level difference or the accumulation of the liquid level difference change, so that the result is more accurate, and the problem of error increase caused by aging due to the problem of operation time is solved.
Description
technical field [0001] The invention belongs to the field of solar energy, in particular to a 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 received by the earth's s...
