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 shell. The upper end of the shell is an opening communicated with the bottom of the cold accumulation tank. A first water communicating plate provided with a sponge is disposed in the shell. 'Z'-shaped bent pipes are disposed below the first water communicating plate. The ports at one end of the bent pipes are fixedly connected with the first water communicating plate. The ports at the other end of the bent pipes are fixedly connected with a second water communicating plate. Two ends of the bent pipes are communicated with the inner cavity of the shell. The ports, connected with the second water communicating plate, of the bent pipes are sealed and provided with water holes. Each 'z'-shaped bent pipe comprises a first straight flow part, a bent part and a second straight flow part, wherein two ends of the bent part are communicated and fixedly connected with the first straight flow part and the second straight flow part, and an included angle smaller than 90 degrees is formed between the first straight flow part and the bent part. A water storage cavity is formed between the second water communicating plate and the bottom wall of the shell. The water distribution device is good in water discharge effect, and thermocline change is avoided.

Description

technical field [0001] The invention belongs to the field of energy storage, and relates to a uniform flow 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 prop...

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 uniform flow device in the water storage system. The uniform flow device in the water storage system has good water discharge effect, ingenious structural design, and will not cause inclined temperature. Layer change, which solves the problem of uneven distribution of water flow from the uniform flow device in the existing water storage system, and excessive flow velocity, which will greatly disturb the inclined temperature layer and cause cooling capacity loss.
