Cold storage system using water distribution modules

Abstract

The invention provides a cold storage system using water distribution modules. The cold storage system using the water distribution modules comprises a cold storage body, the cold storage body comprises 3 to 200 square cold storage modules arranged orderly and compactly, two ends of the cold storage body and the inner side of a waterproof film are further provided with a water distribution system,and the water distribution system comprises water distribution pipes and a plurality of water distribution modules. Compared with the existing art, the size of each cold storage module is small, andcompared with a cold storage box, the number of phase-change cold storage balls capable of being contained is less; but the cold storage modules can be spliced, assembly is very convenient, the phenomenon that the multiple phase-change cold storage balls collide with one another can also be reduced, and the water distribution system can realize full contact between water flow and the phase-changecold storage balls.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning cold storage, and in particular relates to a cold storage system using a water distribution module. Background technique [0002] With the increase of various air-conditioning users year by year, the power consumption of air-conditioning units occupies an increasing proportion in the power grid. The use characteristics of ordinary air conditioners that are turned on during the day and shut down at night intensify the peak-to-valley load difference between the day and night of the power grid. In order to shave peaks and flat valleys and increase the load rate of the power grid, cold storage air conditioners have emerged as the times require. The basic principle of the cold storage air conditioner is to use the surplus low-peak electricity at night to start the refrigerator, store the cold energy through the cold storage medium, and release the cold energy for the air conditioner during th...

Problems solved by technology

The phase change cold storage ball will be deformed due to thermal expansion and cold contraction during the heat exchange process. In the prior art, the phase change cold storage ball has an integrated structure. During the heat exchange process, the shell deformation of the phase change cold storage ball is large. , easy to break, the cold storage ball has a spherical structure, and requires a frame such as a cold storage box or a cold storage module to fix the position. Fix and reduce the damage caused by the collision of multiple cold storage balls together

The cold storage ball is fixed in the cold storage module. In order to give full play to the good cold storage and cooling effect of the phase change cold storage ball, it is necessary to fully combine the refrigerant or water entering the phase change storage module with the phase change material in the cold storage ball. Uniform contact for comprehensive and efficient heat exchange. In the prior art, the refrigerant or water entering the cold storage module is usually directly input into the water tank through a pipe, and its flow rate is large and concentrated. If the refrigerant or water flows into the water tank and then flows out quickly, the brine or water cannot fully and uniformly contact the phase change material, which will easily lead to uneven temperature inside the water tank, and the heat exchange rate of the phase change material will not reach the actual level. Requirements, which ultimately affect the storage and cooling effect of the water tank
