Product Overview


Product Description


Phase change material (PCM) is a substance with a high   heat of fusion which, melting and solidifying at a certain temperature, is capable of storing and releasing large amounts of energy. Heat is absorbed or released when the material changes from solid to liquid and vice versa; thus, PCMs are classified as  latent heat storage (LHS) units.


Latent heat storage can be achieved through liquid→solid, solid→liquid, solid→gas and liquid→gas phase changes. However, only solid→liquid and liquid→solid phase changes are practical for PCMs. Although liquid–gas transitions have a higher heat of transformation than solid–liquid transitions, liquid→gas phase changes are impractical for thermal storage because large volumes or high pressures are required to store the materials in their gas phase. Solid–solid phase changes are typically very slow and have a relatively low heat of transformation.


Organic PCMs

Bio-Based, or Paraffin (CnH2n+2), or carbohydrate and lipid derived.

       ·     Advantages

  o Freeze without much undercooling

  o   Ability to melt congruently

  o   Self nucleating properties

  o   Compatibility with conventional material of construction


        ·    Disadvantages

  o     Low thermal conductivity in their solid state. High heat transfer rates are required during the freezing cycle. Nano composites were found to yield an effective thermal conductivity increase up to 216%.





Salt hydrates (MnH2O)

     ·      Advantages

 o   High volumetric latent heat storage capacity

 o   Availability and low cost

 o   Sharp melting point

     ·      Disadvantages

 o   Incongruous melting and phase separation upon cycling which can cause a significant loss in latent heat enthalpy.


Inorganic Eutectics

    ·     Advantages

o   Some inorganic eutectics have sharp melting point similar to pure substance.

o  Volumetric storage density is slightly above organic compounds.

    ·     Disadvantages

o   They still have the same disadvantages as inorganic PCMs, such as reduced thermal performance upon cycling, corrosivity, high volume change, and high supercooling.
