And the carbon dioxide energy storage system not only can utilize carbon dioxide to store energy, but also can reduce the emission of carbon dioxide and weaken the greenhouse effect. In a carbon dioxide gas-liquid phase-change energy storage system, pipeline flushing (purging) is important, if impurities in a pipeline enter a heat exchanger, the design effect of equipment such as the heat exchanger is affected slightly, and the whole system is paralyzed seriously.
