Energy-storage system includes reservoir, for freezing for the water in reservoir or heating with the energy storage pool cold/heat source equipment of energy storage, use
In by the water in reservoir as refrigerant or heating agent to discharge cold or hot air-conditioning system, controller;The wherein reservoir
The interior capacity regulating plate that is equipped with is to be divided at least two mutually isolated sub-tanks for the reservoir;It further include driving mechanism, institute
It states driving mechanism and connects the capacity regulating plate so that the capacity regulating plate is mobile to adjust subpool relative to the reservoir
The volume of body.
However, water energy storage has the disadvantage that: 1, energy storage density is low;2, tank takes up a large area, and volume is big;3, energy storage is damaged
Lose big, up to 10%-15%;4, easily contaminated if open pond;5, corrosive pipeline problem is serious;6, it is not readily used for
Ability of swimming system is closed, energy consumption is high for output.
