An intelligent energy-saving control method and system for heat storage and discharge of a solid heat accumulator, belonging to the technical field of solid heat storage. The intelligent energy-saving control method for heat storage and discharge of a solid heat accumulator includes the following steps: S1, preset the total amount of heat stored in the heat storage body of the solid heat accumulator within 24 hours from the initial moment of heat storage to the moment of the next day, and The heating outlet temperature of the solid heat accumulator at each time period within the 24 hours; S2, the solid heat accumulator starts to store and release heat, and from the initial moment of heat storage, the heat storage temperature of the heat storage body during the heat storage period is calculated in real time and determined Heat storage time: When the heat storage temperature of the heat storage body is greater than or equal to the real-time temperature of the heat storage body, the heat storage is stopped, and the solid heat storage device continues to release heat until the end of the 24 hours. The intelligent control method and system for heat storage and discharge of solid heat storage and energy saving can reasonably and effectively control the solid heat storage system according to the outdoor temperature, indoor set temperature and building area, which can not only ensure the heating demand of end users, but also save energy .
Description
technical field [0001] The invention relates to the technical field of solid heat storage, in particular to an intelligent control method and system for heat storage and discharge of solid heat storage and energy saving. Background technique [0002] With the development of the times and the improvement of people's living standards, the peak-to-valley difference in power supply is gradually increasing. In order to alleviate this contradiction, my country's power sector promotes peak-to-valley electricity prices and encourages and supports the application of low-valley energy storage technology. Solid heat storage technology has attracted increasing attention due to its safety, environmental protection, and easy-to-adjust characteristics. The heat supply of solid heat storage technology has a significant peak-shaving and valley-filling effect, which enables both power production enterprises and users to obtain corresponding benefits. In the initial heating period in early wi...
