Description
Technical Field
The invention particularly relates to a horizontal energy storage tank applying a combined water distribution device.
Background
The water energy storage technology is an energy storage mode which takes water as an energy storage medium and stores cold or heat by utilizing sensible heat of the water. Taking water cold accumulation as an example, when in cold charging circulation, the air conditioner host stores cold water at 4-7 ℃ by using electricity price valley time, and when in cold releasing circulation, the water pump takes out cold water from the low-temperature end of the energy storage tank, sends the cold water to the air conditioner treatment equipment, and returns water to the high-temperature end of the water energy storage tank. The water energy storage is to store energy by utilizing the temperature difference of water, and can be directly matched with a conventional air conditioning system without adding other equipment. However, such a system can store only sensible heat of water and cannot store latent heat, and thus requires a large volume of the accumulator tank.
Because the country carries out the measures of time-sharing electricity price and expanding peak-valley difference price for users, the electricity price difference exists between the night electricity price and the daytime electricity price, and the electricity of the night low-valley electricity price is utilized, so that the electricity charge can be greatly saved. The economic benefit of energy storage technology will become increasingly apparent today where economic development is rapid.
The water energy storage system stores cold energy by utilizing sensible heat of water, the unit cools the water to a required temperature and stores the water in the energy storage tank for the next day of cold energy supply, and the cold load is eliminated. The size of the stored cold depends on the size of the energy storage tank (the amount of stored cold water) and the energy storage temperature difference. An excellent energy storage system can store more cold energy by maintaining a higher energy storage temperature difference. Meanwhile, the maintenance of the temperature difference can be realized by the technical means of reducing the storage water temperature, improving the backwater temperature, preventing the backwater and the water supplied by the energy storage tank from being mixed and the like. Typically, the water storage temperature is between 4 and 7 ℃, and the temperature is matched with most non-energy storage water chilling units.
In the water energy storage technology, the key problem is the structural form of an energy storage tank, and the energy storage tank is required to be capable of effectively preventing energy storage energy loss caused by mixing of stored water and return warm water.
The water energy storage system has various forms, can be classified according to different characteristics, and has a multi-groove type, a diaphragm type, a natural layering type and a labyrinth type according to the structural form. Among the above methods, the natural layered energy storage method is simple and effective, and is the most economical and efficient method for ensuring the water energy storage system.
Therefore, the person skilled in the art is dedicated to develop a natural layered horizontal energy storage tank using a combined water distribution device.
