The invention discloses an intelligent control method for a low-valley electric solid heat storage device. The main steps include: (1) setting a control target of the low-valley electricity solid heat storage device; (2) detecting the actual output of the pipeline network of the low-valley electricity solid heat storage device (3) Control the rotation speed of the fan according to the difference between the actual output value and the control target; the fan is a heat storage device used in the low-valley electric solid heat storage equipment. The heat stored in the pool heats the water from the equipment. The invention controls the rotation speed of the fan according to the difference between the actual output value and the control target, and then achieves the purpose of controlling the outlet water temperature or output thermal energy power of the low-valley electric solid heat storage equipment, realizes the precise control of the accumulated heat output, and avoids rough The energy waste caused by the energy release is improved, and the utilization rate of the stored heat is improved.
Description
technical field [0001] The invention relates to a control method, in particular to a control method for low valley electricity solid heat storage equipment. Background technique [0002] Low-valley power solid heat storage equipment is an advanced, efficient, clean and energy-saving thermal product. Its principle is: store the cheap electric energy of low-valley power at night in the solid heat storage body through heat exchange, and then pass it through the fan during the peak power during the day. And the circulatory system releases the stored heat for heating or cooling. Low valley power solid heat storage equipment not only reduces electricity costs, but also has the advantages of environmental protection, energy saving, safety, high efficiency, and unattended operation. [0003] However, the existing low-valley power solid heat storage equipment cannot accurately control the output heat, resulting in low utilization of the stored heat. Contents of the invention [0...
