Hybrid Shipping Container
A hybrid shipping container is a shipping system that uses the energy of phase-change material (PCM) in combination with the ability to recharge without removing the media. This ability is known as " cold-energy battery". Currently, this technology is only being used in a limited number of shipping containers. * SkyCell - high energy protection * va-Q-tec - high energy protection combined with vacuum panels * TOWER - very limited energy protection * Peli BioThermal - high energy protection * World Courier Cocoon - similar platform to va-Q-tec A Cold-energy battery works by storing energy to a given temperature and using its thermal mass to maintain this temperature. It can be recharged by being placed in a temperature range applicable to its phase change In chemistry, thermodynamics, and other related fields, a phase transition (or phase change) is the physical process of transition between one state of a medium and another. Commonly the term is used to refer to changes amo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phase-change Material
A phase change material (PCM) is a substance which releases/absorbs sufficient energy at phase transition to provide useful heat or cooling. Generally the transition will be from one of the first two fundamental states of matter - solid and liquid - to the other. The phase transition may also be between non-classical states of matter, such as the conformity of crystals, where the material goes from conforming to one crystalline structure to conforming to another, which may be a higher or lower energy state. The energy released/absorbed by phase transition from solid to liquid, or vice versa, the heat of fusion is generally much higher than the sensible heat. Ice, for example, requires 333.55 J/g to melt, but then water will rise one degree further with the addition of just 4.18 J/g. Water/ice is therefore a very useful phase change material and has been used to store winter cold to cool buildings in summer since at least the time of the Achaemenid Empire. By melting and sol ...

Cold-energy Battery
A cold-energy battery utilizes the properties of an advanced phase-change material (PCM) to maintain temperature as battery thermal management. As with a standard electrical battery An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negat ..., a cold energy battery stores energy and releases depending on the energy demand on it. It can then be recharged by placing in a temperature environment conducive to the phase change properties of the PCM.

Thermal Mass
In building design, thermal mass is a property of the mass of a building that enables it to store heat and provide inertia against temperature fluctuations. It is sometimes known as the thermal flywheel effect. The thermal mass of heavy structural elements can be designed to work alongside a construction's lighter thermal resistance components to create energy efficient buildings. For example, when outside temperatures are fluctuating throughout the day, a large thermal mass within the insulated portion of a house can serve to "flatten out" the daily temperature fluctuations, since the thermal mass will absorb thermal energy when the surroundings are higher in temperature than the mass, and give thermal energy back when the surroundings are cooler, without reaching thermal equilibrium. This is distinct from a material's insulative value, which reduces a building's thermal conductivity, allowing it to be heated or cooled relatively separately from the outside, or even just retain ...
