Problems solved by technology

If such a thermal insulation structure is used to manufacture a high-pressure heat / cold storage device, a thick-walled pressure vessel is required as the tank shell, and the heat capacity of the tank wall will also be greatly increased, so that a large amount of heat / cooling is required in the process of heat / cold storage. Cold energy is used to cool the tank wall, but this part of heat / cooling energy is difficult to recover, which will greatly reduce the heat storage / cold efficiency
In addition, these storage tanks are usually only used for storage of high / low temperature fluid media, and are not filled with solid media for heat / cold storage
