Water distributor in chilled water storage device

Abstract

The invention provides a water distributor in a chilled water storage device, and belongs to the field of energy storage. The chilled water storage device comprises a cold storage pool; the water distributor comprises a sponge, a first stop piece used for limiting the sponge to move downwards and a second stop piece used for limiting the sponge to move upwards; the sponge is composed of a cylindrical cylinder portion and a hemispherical hemisphere portion, one side of the cylinder portion is fixedly connected to the hemisphere portion, the diameter of the cylinder portion is matched with the inner diameter of the cold storage pool, and the sponge is completely immersed in a hot water layer in the cold storage pool; the first stop piece is a hemispherical baffle, multiple through holes are formed in the baffle, the baffle is located in the hot water layer of the cold storage pool and fixedly connected to the inner wall of the cold storage pool, and the hemisphere portion leans against the baffle; the second stop piece is also located in the hot water layer and is an annular stop edge in the shape of a circular ring, and the top edge of the cylinder portion leans against the annular stop edge. The water distributor can enable waterflow to evenly and stably enter the cold storage pool at the slow flow rate.

Description

technical field [0001] The invention belongs to the field of energy storage and relates to a water distributor in a water cold storage device. Background technique [0002] Water storage technology uses the difference in peak and valley electricity prices to store cooling capacity in water during low electricity price periods, and use stored low-temperature frozen water to provide cooling for air conditioners during peak hours of electricity consumption 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 power grid, the power consumption of the air conditioner in the peak time of the power grid can be transferred to the trough of the power grid to save electricity. The most mature and effective cold storage method currently used is natural stratification. [0003] Natural stratification is temperature stratification. Temperature stratified water storage uses the physical propert...

Problems solved by technology

[0007] The object of the present invention is to solve the above-mentioned problems in the prior art, and to provide a water distributor in the water cold storage device. The water device can make the water flow uniform and stable, and the flow rate slowly enters the cold storage tank, which solves the problem of uneven distribution of water flow in the water distributor in the existing water cold storage, which will disturb the thermocline layer and cause cooling loss and other problems.
