Water distribution device in water cold accumulation system

Abstract

The invention provides a water distribution device in a water cold accumulation system and belongs to the field of energy accumulation. The water cold accumulation system comprises a cold accumulation tank. The water distribution device comprises a trapezoid shell with a cavity inside. The top end of the shell is a water inlet end. A plurality of first water holes are formed in the bottom end of the shell. The bottom end of the shell is communicated with the cold accumulation tank. A trapezoid sponge matched with the shell is disposed in the shell. The bottom end of the sponge is abutted against the bottom end of the shell. A circular water guide plate is disposed above the sponge and fixedly connected to the inner wall of the shell. A plurality of second water holes are formed in the water guide plate. A buffer device is disposed above the water guide plate. The buffer device comprises a buffer plate. The buffer plate is located right below the port of the water inlet end of the shell and provided with a plurality of third water holes. A gap is reserved between the buffer plate and the inner wall of the shell. The buffer plate is fixedly connected in the shell. The water distribution device is good in water distribution effect, ingenious in structural design and even and slow in water discharge.

Description

technical field [0001] The invention belongs to the field of energy storage and relates to a water distribution device in a water cold storage system. 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...

Problems solved by technology

[0007] The object of the present invention is to solve the above-mentioned problems in the prior art and provide a water distribution device in the water storage system. The water distribution device has a good water distribution effect, ingenious structural design, uniform and slow water discharge, which solves the problem of uneven distribution of water flow in the water distribution device in the existing water storage system, and the flow rate is too fast, which will greatly disturb the thermoclinic layer and cause cooling capacity loss.
