With the promulgation of the national plan to revitalize the modern logistics industry, the professional logistics of biomedicine, which is related to the safety of people's lives, has been rapidly developed, and phase change energy storage technology has increasingly become the focus of attention. Our company has been committed to the unremitting research and exploration of phase change energy storage technology for many years, and has developed a series of products based on phase change energy storage technology and personalized solutions for special needs.
Broadly speaking, energy storage technology is a technology that stores different forms of energy such as chemical energy, water energy, thermal energy, and electrical energy as needed, and releases it for use when needed. Phase-change energy storage technology is based on the mutual conversion of the three-phase characteristics of substances (ie, solid phase, liquid phase, and gas phase) to achieve energy storage and discharge. Take water as an example: the solid phase is ice, the liquid phase is water, and the gas phase is water vapor. When solid phase ice becomes liquid phase water, it needs to absorb a lot of heat, which is endothermic phenomenon. On the contrary, from liquid phase water to solid phase ice, it needs to release a lot of heat (or absorb a lot of cold), which is exothermic phenomenon. . When the temperature of the material changes, there is a phase change phenomenon and no phase change occurs, and the heat energy absorbed and released differs from several times to hundreds of times. The so-called phase-change energy storage is to use this principle to reasonably configure materials with different phase-change temperatures according to the different temperature requirements of cold chain transportation to achieve the effect of phase-change cold storage and heat storage, and its physical reaction verifies the law of conservation of energy.
Based on the principle of phase change, our company has developed a variety of cold storage products with different phase change materials and phase change temperatures. It is designed into ice packs, ice boxes, ice trays and ice boards of different specifications and sizes. At the same time, the use of new thermal insulation materials and thermal insulation media with independent intellectual property rights to produce various series of thermal insulation boxes and thermal insulation bags. A personalized phase-change cold chain insulation system solution formed by combining phase-change energy storage media with different temperatures (phase-change points) and a combination of new-type insulation boards. The products produced by these schemes do not need electricity in use and can be recycled, achieving the purpose of saving energy, reducing pollution, and reducing carbon emissions.
When it comes to cold chain logistics in daily applications, it is associated with refrigeration. But in fact, in many cases, cooling and heat preservation are relative concepts. That is to say, the application in cold chain logistics and transportation is not only reflected in refrigeration technology, but also in heat preservation technology.
Our company's use of phase change energy storage technology in cold chain logistics and transportation is widely used, mainly involving a variety of cold chain products in the cold chain logistics system, including aviation cold chain transportation, land cold chain transportation, and railway transportation. At the same time, according to the needs of different environments, the core technology of phase change energy storage (cold storage, heat storage) can also provide professional customized solutions such as cold storage in summer, heat preservation and cold chain insulation in winter.
