The present invention proposes a novel heat storage and release experimental system capable of multi-mode operation. The experimental system includes a heating subsystem, a heat storage and release subsystem, a cooling subsystem and a heat exchange subsystem, which solves the problem of the prior art in the laboratory. The test situation is single, and it is difficult to simulate the heat storage and release process under actual operating conditions in detail. It can realize open heat storage and release operation mode, closed cycle heat storage and release operation mode, open heat storage and release system and closed heat storage and release The system can freely switch modes, and a variety of variable working conditions experiments under different operating modes. This new heat storage and release experimental system can be carried out under laboratory conditions for different application scenarios and different operating modes (such as solar heat storage and waste heat recovery). Heat storage and release and energy storage device experiments, and can meet the research and development and testing of key components in low-temperature, medium-temperature, and high-temperature heat storage and release systems.
Description
technical field [0001] The invention relates to a heat storage and release experimental system capable of realizing multi-mode operation, and belongs to the technical field of heat storage equipment. Background technique [0002] Heat storage technology uses heat storage materials as the medium to store thermal energy such as solar heat, geothermal heat, industrial waste heat, and low-grade waste heat, which can effectively solve problems caused by uneven temporal and spatial distribution or mismatch between energy supply and demand. It is a technology gradually developed to maximize the energy utilization rate of the entire system and reduce energy utilization costs. Heat storage technology is of great strategic significance for building a "clean, low-carbon, safe and efficient" modern energy industry system, promoting the supply-side reform of my country's energy industry, and promoting the transformation of energy production and utilization methods.
