Description

technical field

[0001] The invention relates to the field of heat storage devices, in particular to a thermochemical adsorption heat storage device. Background technique

[0002] As the world's energy consumption increases and fossil fuels are depleted, sustainable development is gaining more and more attention. Making better use of existing energy sources and switching from existing energy sources to renewable energy sources are two effective ways to save energy and reduce emissions. In order to cope with the differences in time, space and power between the energy supply side and the demand side, and to improve the intermittent and unstable problems of renewable energy such as solar energy, energy storage technology provides an ideal solution. Compared with the storage of mechanical energy and electrical energy, thermal energy storage technology has the advantages of low cost, large capacity, and is suitable for green buildings and solar collectors. Therefore, thermal ene...
