Efficient air cooled chilled water storage system

Abstract

The invention provides an efficient air cooled chilled water storage system and belongs to the field of energy storage. The system comprises a cold accumulation pool and a high-pressure gas tank, wherein an air pump is connected to the high-pressure gas tank, an air inlet pipe is connected with the air pump and is communicated with the outside, and an air outlet pipe is communicated with the high-pressure gas tank; the outer end of the air outlet pipe is communicated with the high-pressure gas tank, the inner end of the air outlet pipe stretches into the bottom of the cold accumulation pool from the top of the cold accumulation pool, and the inner end of the air outlet pipe is located at one side of the bottom of the cold accumulation pool and is distributed at the bottom of the cold accumulation pool in a bent mode; the inner end of the air outlet pipe is composed of a plurality of bent parts, a port of the inner end of the air outlet pipe faces the bottom of the cold accumulation pool downwards, and a cylindrical sponge block is arranged above the bent parts and fixedly connected to the inner wall of the cold accumulation pool; a cold air pipe is arranged on the top of the cold accumulation pool and leads into a room, and an electromagnetic valve is arranged on the air outlet pipe. The system is high in refrigeration efficiency and high in cold utilization rate, cold air is fresh, and electricity cost is low.

Description

technical field [0001] The invention belongs to the field of energy storage and relates to a high-efficiency air-cooled water 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 property...
