Water-storage air-conditioning is an energy-saving air-conditioning method that utilizes the peak-to-valley electricity price difference of the power grid, uses chillers to store cold in the pool at night, and cools the pool during the day while the main engine runs off-peak.

It has the characteristics of small investment, reliable operation, good cooling effect, and obvious economic benefits. It can save users considerable annual operating costs of central air conditioning every year. It can also realize large temperature difference water supply and emergency cold source. In the case of complicated debugging and difficult promotion, water storage is economical and simple, and the fire pool of large buildings can be used for cold storage. Therefore, water storage technology has broad development space and application prospects. The benefits are reflected in the ability to balance the power grid load, reduce power plant investment, and purify the environment, which is in line with the development direction of my country's industrial policy.
The water storage technology utilizes the electricity price difference between peaks and valleys to store cold energy in water during the low electricity price period, and uses the stored low-temperature chilled water to provide cooling for air-conditioning during the peak electricity consumption period during the day. When the use time of the air conditioner is synchronized with the use time of the non-air conditioner and the peak and trough of the grid, the power consumption of the air conditioner during the peak time of the grid can be transferred to the trough of the grid, so as to achieve the purpose of saving electricity bills. The mature and effective cold storage method currently used is natural stratification.
