Description

Technical Field

[0001] This new type belongs to the technical field of cold storage energy storage and energy saving, and specifically relates to a cold storage energy storage mechanism. Background Art

[0002] A cold storage (English: Cold Store) is a type of refrigeration equipment. A cold storage refers to a device that uses artificial means to create an environment with a temperature or humidity different from the outside, and is also a constant temperature and humidity storage device for items such as food, liquids, chemicals, medicine, vaccines, and scientific experiments. Cold storages are usually located near transportation ports or the place of origin. Compared with a refrigerator, a cold storage has a larger refrigeration area and the same refrigeration principle.

[0003] For a cold storage, its refrigeration system has huge energy consumption. To solve the energy consumption problem, people choose to introduce the energy storage technology. During the low electricity load period at night, when the electricity consumption trough occurs, a refrigerator is used for refrigeration, and the sensible heat or latent heat characteristics of the energy storage medium are utilized to store the cold energy; during the day when the electricity load is high, the stored cold energy is released to meet the needs of the production process. Document CN117824255A discloses a movable cold storage energy storage and cold supply intelligent vehicle and a cold storage system based on this technology, including a transport vehicle and a cold supply mechanism; the transport vehicle includes a vehicle body and an ice slurry tank; the ice slurry tank is used to hold ice slurry, and it is installed on the vehicle body and is provided with a slurry outlet and a slurry return port communicating with its inner cavity; the cold supply mechanism includes a housing, a heat exchange pipeline, a fan, and an ice slurry pump. The housing is installed on the vehicle body and has a heat exchange cavity, and is provided with an air inlet and an air outlet communicating with the heat exchange cavity. The two ends of the heat exchange pipeline are respectively communicated with the slurry outlet and the slurry return port, and at least part of it is located in the heat exchange cavity. The fan is installed on the housing and corresponds to the heat exchange cavity, and is used to blow air from the air inlet to the air outlet. The ice slurry pump is arranged on the heat exchange pipeline to enable the ice slurry in the ice slurry tank to circulate in the heat exchange pipeline. This solution can reduce the temperature of the cold storage while reducing the electricity consumption during the day and the power load during the peak electricity consumption period in summer, and the transport vehicle can move in the cold storage, with good flexibility. However, this invention has the following problems:

[0004] 1. It is necessary to additionally configure equipment such as a vehicle body. Although it is flexible to move, it occupies a large space;

[0033] Working principle of the present invention:

[0034] The Teslin refrigerator works, and transfers the cold quantity to the heat dissipation mechanism through the cold end. The heat dissipation mechanism transfers the cold quantity to the fourth heat transfer pipe. When the first temperature sensor detects that the temperature inside the ice tank is higher than the set value, the circulation pump corresponding to this ice tank is started. The refrigerant circulates along the loop formed by the fourth heat transfer pipe, the output main pipe, the second heat transfer pipe, the first heat transfer pipe, the third heat transfer pipe, and the input main pipe, and cools the inside of the ice tank. After the temperature drops to a certain value, the circulation pump and the Teslin refrigerator stop working. The cold storage is cooled by several ice tanks. If the second temperature sensor detects that the temperature is higher than the set value, the controller can start the circulation pumps corresponding to all the ice tanks for overall refrigeration of the ice storage. The refrigeration mechanism of the present invention can be powered by the electric energy provided by the solar energy, or can make ice for the ice tanks during the low electricity consumption period at night, so as to provide cold storage for the period when the electric energy of the storage battery is insufficient and it is not the low electricity consumption area.
