Natural layering water cold accumulation device

Abstract

The invention discloses a natural layering water cold accumulation device. The device comprises a cold accumulation trough, an upper high-temperature water pipe and a lower low-temperature water pipe communicated inside and outside the cold accumulation trough, an upper water distributor communicated with the upper high-temperature water pipe and provided with an upward water distributing nozzle, and a lower water distributor communicated with the lower low-temperature water pipe and provided with a downward water distributing nozzle. The natural layering water cold accumulation device is characterized in that the water distributing nozzles are provided with nozzle angles and flow deflectors arranged in the axial direction of the water distributors along the nozzle angles. The device reduces the thickness of a thermocline by 0.1 m and the practical water distributing height of the upper water distributor and the lower water distributor by 0.1 m respectively; and meanwhile, the device effectively increases the utilization rate of the capacity of a cold water accumulation trough and increases the effective cold accumulation height and effective cold release height of the cold water accumulation trough by 0.3 m, thereby realizing efficient cold accumulation and cold release.

Description

technical field [0001] The invention relates to a cold storage device, in particular to a natural stratified water cold storage device. Background technique [0002] An obvious feature of my country's power supply in recent years is the difference between the "peak" load during the day and the load at night in summer. [0003] The peak-to-valley difference of the load in the "valley period" is very large, which reduces the load rate of the power grid. Centralized air conditioners are important consumers of electricity and are also the main cause of the peak-to-valley load difference of the power grid, and cold storage air conditioners are an effective way to solve this problem. The so-called cold storage air conditioner is to use the power in the low-peak period of the power grid load (such as night) for cooling, and store the cold energy by using the cold storage medium, and release the cold energy for building during the peak load period of the power grid (such as daytime...

Problems solved by technology

Because, at the beginning of cooling release, the warm water after heat exchange does not directly return to the uppermost part of the water surface, but has a certain height from the top. Due to the high temperature of the return water and the cold water stored in the original space, the water temperature Under the effect of density difference, the high and low temperature water is mixed rapidly, causing the water temperature in this space to rise; and at the end of the cooling release, although the water temperature in the space from the lower water distributor to the bottom of the pool is low, due to the lower The outlet of the water distributor is a certain height from the bottom, so this part of low-temperature water cannot be used
