Ecologically Environmentally Friendly Building Wall Phase Change Energy Storage And Energy-Saving Insulation Material

PCM characteristics:

• PCMs latent heat storage can be achieved through solid–solid, solid–liquid, solid–gas and liquid–gas phase change.
• However, the only phase change used for PCMs is the solid–liquid change. Liquid-gas phase changes are not practical for use as thermal storage due to the large volumes or high pressures required to store the materials when in their gas phase.
• Liquid–gas transitions do have a higher heat of transformation than solid–liquid transitions.
• Solid–solid phase changes are typically very slow and have a rather low heat of transformation.

• Phase change materials store or release large amounts of heat at almost constant temperatures during the phase transition between solid and liquid. Due to the high purity and special composition of phase change materials, phase change materials have remarkable latent heat storage capacity in a narrow temperature range. Depending on the melting point, different temperatures can be applied to different application scenarios.
• The latent heat value of solid-liquid phase change materials is generally 200-220 J/g. Organic phase change materials have a wide range of optional melting temperatures.
