Energy-saving chilled water storage structure

Abstract

The invention provides an energy-saving chilled water storage structure and belongs to the field of energy storage. The energy-saving chilled water storage structure comprises a cold energy storage tank and a high-pressure air tank. The high-pressure air tank is connected with an air pump. The air pump is connected with an air inlet pipe. The air inlet pipe is communicated with the outside. The high-pressure air tank is connected with an air outlet pipe. The air outlet pipe is located at the bottom of the cold energy storage tank. The bottom of the cold energy storage tank is provided with a choking mechanism. The choking mechanism comprises a limiting plate arranged on the bottom wall of the cold energy storage tank. The limiting plate divides the bottom space of the cold energy storage tank into two chambers, wherein one chamber is internally provided with the air outlet pipe. The choking mechanism further comprises an air guide plate fixed to the inner wall of the cold energy storage tank. The other end of the air guide plate is in a suspended state. The air guide plate inclines downwards. An air passing opening is formed between the air guide plate and the limiting plate. Air discharged out of the air outlet pipe can pass through the air passing opening to move toward the bottom of the cold energy storage tank. The top of the cold energy storage tank is provided with a cold air pipe. The cold air pipe leads into a room. The air outlet pipe is provided with a solenoid valve. The chilled water storage structure is high in refrigerating efficiency and cold energy 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 an energy-saving water cold storage structure. 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 of ...
