Abstract

The invention provides a method for descaling the heat collector by pressure difference. An electric heater is installed in the heat collector box, and the electric heater operates at night. Comparing the data, obtaining the accumulation of the pressure difference or the change of the pressure difference. When it is lower than the threshold value, the controller controls the electric heater to stop heating or continue heating. In the present invention, through the operation of the electric heater, the heat collecting tube is continuously vibrated according to the pressure difference data to perform the descaling work.

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...
