WEBINAR: Thermal Storage and Management using PCM (Phase Change Material), time: 30:28


Thermal energy storage (TES) systems provide several alternatives for efficient energy use and conservation. Phase change materials (PCMs) for TES are materials supplying thermal regulation at particular phase change temperatures by absorbing and emitting the heat of the medium. To increase the duration of thermal control within a given temperature range, PCMs are normally selected such that their phase change temperature is within the required temperature range of the product being shipped (i.e. +5°C PCM is used to meet a +2°C to +8°C temperature requirement). Properties of phase change materials. Phase change materials exist in an amorphous and one or sometimes several crystalline phases, and they can be rapidly and repeatedly switched between these phases. The switching is typically induced by heating through optical pulses or elec- . To store thermal energy, sensible and latent heat storage materials are widely used. Latent heat TES systems using phase change material (PCM) are useful because of their ability to charge and discharge a large amount of heat from a small mass at constant temperature during a phase transformation like melting-solidification. Phase change materials (PCMs) used for the storage of thermal energy as sensible and latent heat are an important class of modern materials which substantially contribute to the efficient use and conservation of waste heat and solar by: Springer Science+Business Media, LLC All rights reserved.

  1. Dazshura

    Quite good topic

  2. Zulkisar

    I am final, I am sorry, but it is all does not approach. There are other variants?

  3. Gardasida

    I confirm. All above told the truth. We can communicate on this theme. Here or in PM.

  4. Nibar

    And other variant is?

  5. Brashura

    You are not right. I am assured. I suggest it to discuss. Write to me in PM, we will communicate.
