The present disclosure relates to the technical field of energy conservation and emission reduction, especially to an energy storage energy system.
Under the global dual-carbon target, all walks of life in the world take carbon neutral and carbon peak as the development direction, especially China's heating direction has been adjusted to the development route of coal to electricity.
The global refrigeration and refrigeration air conditioning industry use refrigerants to achieve refrigeration through the reverse Carnot cycle of refrigeration compressor. Refrigerant is recognized as one of the main culprits of the greenhouse effect in the world, and the Montreal International Convention has a strict limit on its use. After the signing of the convention, the world is developing low-fluorine green refrigeration systems, as well as refrigerant-free refrigeration and air conditioning systems.
Coal-fired power generation has a more serious greenhouse effect, with the global vigorous development of nuclear power, wind power and photovoltaic power generation to replace coal-fired power generation. China's wind power and photovoltaic power have become a world leader. However, the global abandonment of wind power and photovoltaic power generation has become a reality, and the rejection of urban power grids to accept wind power and photovoltaic power generation, has led to a huge wind power and photovoltaic power field development constraints bottleneck. The world should develop a way to overcome the losses of wind power and photovoltaic power generation, and at the same time find new ways to accept wind power and photovoltaic power generation market. In addition, one of the biggest defects and drawbacks affecting wind power and photovoltaic power generation is that wind power is restricted by wind, no wind, strong and weak wind, and its power generation is completely dependent on natural wind conditions; photovoltaic power generation is subject to the interference of nighttime, overcast, rain and snow weather. Therefore, the extremely unstable wind power and photovoltaic power generation must rely on the electricity storage and charging mode to achieve stable power supply. However, the use of battery charging and storage of electric energy increases the huge cost of battery, while the pollution of the battery production process is extremely serious, if the comprehensive evaluation, mass production of batteries, as well as battery scrap processing, will cause huge pollution to society, and the development of wind power and photovoltaic power generation environmental benefits compared,, the wind power and photovoltaic power generation are not much significance too society and environmental protection. If wind power and photovoltaic power generation do not adopt the development of electric storage, eliminate the production of a large number of batteries and eliminate the pollution brought to the society, then the development of energy storage to replace the road of development of power storage mode, its wind power and photovoltaic power generation are no longer completely dependent on the development path of battery storage, its environmental protection and social significance is great.

In addition, the terms “low temperature” and “high temperature” are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, the features defined with “low temperature “and” high temperature” may explicitly or implicitly include one or more of the features.

The present disclosure subverts the refrigeration technology system of the refrigerant-type refrigeration compressor, and thoroughly eliminates the world- recognized “refrigerant” that causes one of the greenhouse-effect cells. Not only is the significant environmental protection significance, but the stored energy can be directly sold as a product, so that the economic benefit is far better than that of wind power. And after the photovoltaic power generation is charged by using the battery, discharging the network for sale, or pumping and storing energy, and after the air is compressed and stored, the marketing profit for high temperatureary power generation is greater, because there is no loss of high temperatureary energy conversion. A foundation is laid for diversification and wide utilization of wind power and photovoltaic power generation energy storage, and the problem of power abandoning rate of wind power, photovoltaic power generation and power grid can be completely solved.
China refrigeration industry, the manufacturing technology of the refrigeration compressor is far behind the western developed country, the used refrigeration compressor is monopolized by several foreign brand products, not only is the manufacturing technology use cost, but also the profit of the product and the purchase cost of the spare parts of the imported spare parts, and the national year is cut by the foreign quotient. In addition, the refrigeration compressor technology is complex, and generally freezing and air conditioning enterprises do not specially maintain professional technicians. Therefore, each year of training fee, dedicated operation and maintenance costs are huge.
The liquid-air refrigeration subverts the refrigeration compression mechanism to cool, and the expensive and complex refrigeration compressor system becomes a cheap liquid-empty product for storage and transportation, and is as convenient and simple as the use of tap water, so that people can use the refrigeration house system and the central air conditioner.
The liquid-air cold storage directly replaces the refrigeration compression mechanism to cool, completely eliminating the cut-off Chinese chives and the huge operation and maintenance costs. The liquid-air refrigeration is simple, safe and convenient as the faucet is opened, and it is not necessary for special personnel to perform operation and maintenance and management in any unit, and the operation cost is far lower than the refrigeration technology cost of the refrigeration compressor.

Because the molten salt heat storage tank is limited by the maximum thermal temperature of the inner material, the molten salt heat storage can reach about 600° C. If the molten salt heat is stored in a high temperature of more than 600° C., it is not impossible, but the material structure of the inner is very expensive, and its cost performance is very low, the gain is not worth the loss. Therefore, fire-resistant insulation brick material is adopted, and the heat storage temperature of molten salt can be as high as about 1200° C. But it can not be stored to too high, because ordinary electric wire over 1400° C. will melt and evaporate.
