Embodiment approach 1

[0034] Embodiment 1: The cold storage device adopts a cylindrical cold storage water tank, and the water distributor adopts an octagonal arrangement, such as Figure 4 shown. The water distributor adopts a circular cross-section, and the water distribution outlet adopts a slit radial flow distribution nozzle with a diffusion angle, and a deflector is arranged along the diffusion angle, and the deflector and the flow equalization damping layer together form a stable flow layer. The deflectors are made of plastic material, and each group is composed of two deflectors, which are laid along the axial direction of the water distributor, and the two deflectors form a certain angle, such as Figure 2-a , Figure 2-b , Figure 3-a , Figure 3-b shown. And in addition to the position connected with the outlet of the water distributor, other parts of the deflector are provided with small holes with a diameter of less than 1cm at a certain interval. A flow equalizing damping layer i...

Embodiment approach 2

[0035] Implementation mode 2: The cold storage device adopts a square cold storage tank, and the water distributor adopts an H-shaped arrangement, such as Figure 5 shown. The flow equalization damping layer adopts multi-layer nylon fabric, and the rest of the structure is the same as that of Embodiment 1.

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...
