An integrated cold storage and heat storage device

Abstract

The invention discloses a cold storage heat storage integrated device. The integrated cold storage and heat storage device includes an energy storage tank body, wherein a heat pipe uniform temperature heat exchange device, an upper water distributor, and a lower water distributor are arranged inside the energy storage tank body, and the upper water distributor is arranged on the side of the energy storage tank body. The upper and lower water distributors are arranged at the lower part of the energy storage tank. The integrated device for cold storage and heat storage not only realizes the process of "cold storage and cooling" and "heat storage and heat release" by installing a heat pipe uniform temperature heat exchange device in the energy storage tank, but also realizes the transformation of the medium in the energy storage tank. Uniform cooling and heating. At the same time, an upper water distributor and a lower water distributor are arranged in the energy storage tank to further make the medium in the energy storage tank be heated or cooled evenly. Moreover, under the same cooling and heating external conditions, the integrated cold storage and heat storage device and its corresponding cold storage and heat storage system occupy a smaller area, lower initial investment, higher operating efficiency, longer service life, and easier maintenance. convenient.

Description

technical field [0001] The invention relates to an energy storage device, in particular to an integrated device for cold storage and heat storage. Background technique [0002] Under normal circumstances, cold storage devices, heat storage devices, or devices capable of storing heat while storing cold are collectively referred to as energy storage devices. In the cold storage and heat storage system using energy storage devices, many equipment such as refrigeration hosts, boilers, ice storage devices, heat storage devices, plate heat exchangers, etc. are required to realize the above different functions. This brings many problems such as complex system, large floor space, high cost, low system operating efficiency, and the current cold storage device and heat storage device also have different problems. [0003] For example, in a conventional ice storage system, the refrigeration main unit and the ice storage device are generally separated, and the static ice storage coil r...

AI Technical Summary

Problems solved by technology

The heat storage boiler has the following defects: ①The heat storage system has many equipments and the system is complex; ②Electric boilers and heat storage tanks need to be connected by pipelines, and the installation process is complicated; ③The on-site construction period is long and the investment cost is high

④The electric heating tube is in direct contact with water, which is easy to scale; ⑤When the wall of the electric heating tube is damaged due to scaling or corrosion, it will cause water electrification and bring potential safety hazards

[0005] Moreover, the existing heat storage equipment or cold storage equipment also has a common problem of high energy consumption under a single target.

These devices fail to achieve efficient and comprehensive utilization of energy, and there are few devices on the market that can store heat while storing cold
