A phase change material cold storage system

Abstract

The invention discloses a phase change material cold storage system, which relates to the technical field of phase change materials. The phase change material cold storage system includes a base and an ice plate. A cold storage box is arranged on the outside of the top of the base. The surface is provided with a chute, the inner surface of the chute is arranged with a sliding clamping plate, and the inner surface of the sliding clamping plate is connected with a connecting seat, the ice plate is placed on the outer surface of the connecting seat, and the cold storage box The middle section on the right side is connected with a water inlet pipe. In this phase change material cold storage system, copper wire mesh is arranged on the upper and lower sides of the ice plate, which enables the copper wire mesh to be in contact with the organic phase change material. By setting the copper wire mesh, when the cooling water flows to the surface of the ice plate, The cooling water can quickly exchange heat with the organic phase change material through the copper wire mesh inside the ice plate, thereby improving the speed and efficiency of heat exchange of the organic phase change material.

Description

technical field [0001] The invention relates to the technical field of phase change materials, in particular to a cold storage system for phase change materials. Background technique [0002] A phase change energy storage material refers to a material that absorbs or releases a large amount of latent heat to the surrounding environment due to a change of state at a certain temperature. Ice (solid) at 0°C absorbs heat and turns into water at 0°C, which is a phase transition process. Central air conditioners are suitable for large public places, such as shopping malls, offices, etc., and electricity consumption is divided into trough periods and peak periods. Electricity bills vary greatly. How to use electricity reasonably and use the difference between peak and valley electricity prices to save economic expenses has become an urgent problem that needs to be solved. The application of phase change materials in the central air-conditioning system of water systems can realize c...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a phase change material cold storage system, which solves the problem that the existing phase change material cold storage system has a relatively single cold storage and cooling mode in the above-mentioned background technology, and cannot be used in a more complicated air-conditioning environment. In addition, the working stability of the phase change material is not good, and the thermal conductivity is poor during the cold storage and cooling process, which leads to the problem that the cold storage system cannot perform good heat transfer.
