Description

A water cold storage refrigeration system

technical field

The utility model belongs to the field of energy storage and relates to a water cold storage refrigeration system.

Background technique

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.

Natural stratification is temperature stratification. Temperature stratified water storage uses the physical property of water with different densities at different temperatures, and relies on the density difference to keep warm water and cold water separated to avoid cooling loss caused by mixing cold water and warm water.

Water has the highest density at around 4°C, and the density gradually decreases with the increase of water temperature. Using this physical characteristic of water, the water with low temperature is stored in the lower part of the pool, and the water with high temperature is stored in the upper part of the pool. . A well-designed temperature stratified water storage tank forms a heat and mass exchange layer between the upper warm water zone and the lower cold water zone. A stable heat and mass exchange layer with small thickness is the key to improve the efficiency of cold storage.

The existing relatively mature technology is to use the natural stratification of temperature to realize the work of the system, and to realize the cooling of the room by passing the refrigerated water through the cooling device. The problem is that the structure of the existing cooling device is very complicated, and the cooling device usually Cooling is done through a device similar to the internal unit of the air conditioner. Due to the limited specifications of the internal unit of the air conditioner, the cooling efficiency is low. During the initial cooling, the temperature difference between one end of the time and the other end of the room is slightly larger, and the cooling efficiency is slow. In addition, the existing water storage system Cooling is carried out by alternating heat between cold water and the room. This way of heat exchange takes a certain amount of time, resulting in slow cooling efficiency.
