Device integrating cold accumulation and heat accumulation

Abstract

The invention discloses a device integrating cold accumulation and heat accumulation. The device integrating cold accumulation and heat accumulation comprises an energy accumulation tank body. The energy accumulation tank body is internally provided with a heat pipe temperature equilibrium heat exchange device, an upper water distributor and a lower water distributor. The upper water distributor is arranged on the upper portion of the energy accumulation tank body, and the lower water distributor is arranged on the lower portion of the energy accumulation tank body. According to the device integrating cold accumulation and heat accumulation, the energy accumulation tank body is internally provided with the heat pipe temperature equilibrium heat exchange device, the process of cold accumulation and cold release and the process of heat accumulation and heat release can be achieved, and temperature equilibrium refrigeration and temperature equilibrium heating can be conducted on a mediuminside the energy accumulation tank body; and meanwhile, the energy accumulation tank body is internally provided with the upper water distributor and the lower water distributor, and the medium inside the energy accumulation tank body is further heated or cooled uniformly. In addition, under the same cold supply and heat supply external condition, the device integrating cold accumulation and heataccumulation and a corresponding cold accumulation and heat accumulation system thereof are smaller in occupied area, lower in initial investment, higher in operating efficiency, longer in service life and more convenient to maintain.

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
