随着国家振兴现代物流产业规划的出台，关系人民生命安全的生物医药专业物流得到快速发展，相变蓄能技术已经日益成为人注目的焦点。我公司多年致力于相变蓄能技术的不懈研究、探索，开发出一系列基于相变蓄能技术的产品及针对特别需求的个性化解决方案。

       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.

       广义地说，蓄能技术就是将化学能、水能、热能、电能等不同形式的能根据需要储存起来，在需要时释放出来提供使用的技术。相变蓄能技术是根据物质的三相特质（即固相、液相、气相）之间的相互转换实现蓄能及放能。以水为例：固相为冰、液相为水、气相为水蒸气。当固相冰变成液相水需要吸收大量的热这就是吸热现象，反之从液相的水变成固相的冰要放出大量的热（或者是吸收大量的冷）这就是放热现象。物质材料在温度变化时有相变现象发生和没有相变发生，其吸收和放出的热能相差数倍到数百倍。所谓相变蓄能就是利用这个原理，按冷链运输不同的温度需求将不同相变温度的材料进行合理配置达到相变蓄冷蓄热的效果，其物理反应验证了能量守恒定律。

        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.

        我公司依据相变原理研制出不同相变材料和相变温度的多种蓄冷产品。将其设计成不同规格尺寸的冰袋、冰盒、冰排及冰板。同时应用新型保温材料及拥有自主知识产权的保温介质制作出各种系列保温箱、保温包。通过不同温度（相变点）的相变蓄能介质及由新型保温板材组合搭配而成的个性化相变冷链保温系统解决方案。这些方案制作的产品在使用中均无需用电，可循环利用，达到了节约能源，减少污染，减少碳排放的目的。

       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.

       在日常应用中一提到冷链物流就会联想到制冷。但实际上，在很多的时候制冷和保温是相对的概念。也就是说在冷链物流运输中的应用不止体现在制冷技术，同时也体现在保热技术。

        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.

       我公司利用相变蓄能技术在冷链物流运输中的应用比较广泛，主要涉及冷链物流系统中包括航空冷链运输、陆路冷链运输、铁路运输等多种冷链产品。同时根据不同环境的需要，相变蓄能（蓄冷、蓄热）核心技术还可以提供夏季保冷，冬季保热冷链保温等专业定制方案。

       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.
