Novel inflatable chilled water storage system

Abstract

The invention provides a novel inflatable chilled water storage system and belongs to the field of energy storage. The chilled water storage system comprises a chilled water storage pool and further comprises a high pressure gas tank, the high pressure gas tank is connected with an air pump, an air inlet of the air pump is communicated with a first air inlet pipe, one end of the first air inlet pipe is communicated with the air pump, the high pressure gas tank is connected with a first air outlet pipe, the outer end of the first air outlet pipe is communicated with the high pressure gas tank, and the inner end of the first air outlet pipe is located at the bottom of the chilled water storage pool. An air distribution plate is arranged at the bottom of the chilled water storage pool, the inner end of the first air outlet pipe penetrates through the air distribution plate, and air holes are formed in the air distribution plate. A cold air pipe is arranged at the top of the chilled water storage pool, the first air outlet pipe is provided with a first electromagnetic valve, each air hole is provided with a first sponge sheet, the first air inlet pipe is provided with a second electromagnetic valve, the air pump is connected with a second air inlet pipe, and the second air inlet pipe is provided with a third electromagnetic valve. The air pump is further connected with a second air outlet pipe, the other end of the second air outlet pipe is led to the bottom of the chilled water storage pool, and the second air outlet pipe is provided with a fourth electromagnetic valve. The chilled water storage system has high refrigerating efficiency and a high cold capacity utilization rate, cold air is fresh, and the electricity price is low.

Description

technical field [0001] The invention belongs to the field of energy storage and relates to a novel air-filled 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 property...
