Description
Technical Field
[0001] The utility model relates to the technical field of energy storage equipment, in particular to an energy storage equipment combining ice cold storage and water heat storage. Background Art
[0002] Water energy storage uses the sensible heat of water to store cold or heat. The energy storage device is composed of a coil immersed in a water-filled energy storage tank. When storing cold, the low-temperature refrigerant produced by the chiller circulates through the coil, causing the outer surface of the coil to freeze and store cold. When releasing cold, the higher-temperature refrigerant circulates in the coil, causing the ice layer outside the coil to melt from the inside to the outside, releasing cold. Water heat storage heats water to a certain temperature so that heat energy is stored in the water in the form of sensible heat. When heat is needed, it is released to provide heating needs.
[0003] In the current existing technology, ice cold storage or water heat storage will cause the temperature in the energy storage tank to change, causing the water in the energy storage tank to freeze or evaporate. The energy storage tank usually has a certain degree of sealing, which causes the space volume inside the energy storage tank to expand, causing the surface of the energy storage tank to bulge. As time goes by, the bulging degree of the energy storage tank becomes larger and larger, eventually causing damage to the energy storage tank, making it inconvenient to use the energy storage equipment.
