Thermocline-free cool storage device

Abstract

The invention belongs to the technical field of cool storage devices and particularly relates to a thermocline-free cool storage device which solves the problems that a thermocline of an existing cool storage device influences the effective volume for cool storage and the like. The thermocline-free cool storage device comprises a cool storage tank with a cavity. A first bag and a second bag are arranged in the cool storage tank. The whole cavity is filled with the first bag and the second bag. A cool storage liquid filling and releasing control mechanism is arranged between the first bag and the second bag and can enable cool storage liquid in the first bag to be injected into the second bag so as to control the first bag to shrink and the second bag to expand and enable cool storage liquid in the second bag to be injected into the first bag so as to control the second bag to shrink and the first bag to expand. The cool storage liquid filling and releasing control mechanism is connected with a terminal. The thermocline-free cool storage device has the advantages of being simple and reasonable in structure, good in cool storage effect, high in cool storage efficiency, capable of eliminating influence of the thermocline on the effective cool storage volume, uniform in temperature distribution, small in occupied area, convenient to use and low in operating cost.

Description

technical field [0001] The invention belongs to the technical field of cold storage equipment, and in particular relates to a non-cline thermosphere cold storage equipment. Background technique [0002] The cold storage system is a peak-shaving energy-saving technology. Due to its low initial investment, simple system, and convenient maintenance, it is not only suitable for new buildings, but also can be used for expansion or transformation of existing systems, making it have a good application prospect. . Its main principle is to turn on the refrigeration main engine at night when the power grid load is low, and store the cold energy produced by it with a cold storage medium of 4-6 degrees; Hosts avoid peak runs. The storage and withdrawal of cold storage medium is the core technology of cold storage system. In order to improve the cold storage effect of the cold storage tank and prevent the mixing of high temperature and low temperature water, the structural form of the...

AI Technical Summary

Problems solved by technology

[0004] The above scheme solves the problem of large thickness of the thermocline layer of the existing cold storage equipment to a certain extent, but this scheme still cannot fundamentally solve the problem that the thermocline layer affects the effective volume of the cold storage tank. In addition, this scheme still exists Problems: complex structure, low cold storage efficiency, poor cold storage effect, uneven temperature distribution, large floor area, inconvenient use, high operating costs, etc.
