Types of building phase change energy storage materials:
1. Organic phase change materials
- Paraffin is a common organic phase change material, which has the advantages of high latent heat of phase change, good chemical stability and relatively low price. Different chain lengths of paraffin wax can provide different phase change temperatures, which can be selected according to the specific needs of the building.
- Fatty acids and their ester phase change materials usually have good thermal stability and a suitable phase change temperature range, and most of them are renewable resources, in line with the concept of environmental protection.
2. Inorganic phase change materials
- These materials have high latent heat of phase transition, low cost and good flame retardancy.
- For example, sodium sulfate hydrate will undergo a phase transition process of dehydration and rehydration at a certain temperature, absorbing or releasing a lot of heat.
3. Composite phase change materials
- In order to overcome the shortcomings of organic and inorganic phase change materials, composite phase change materials came into being. It is the combination of organic and inorganic phase change materials or other additives through physical or chemical methods.
- For example, phase change materials can be encapsulated in porous media, such as expanded graphite, diatomaceous earth, etc., to improve the thermal conductivity and stability of the material.
- Combining the advantages of different materials, such as good thermal stability, suitable phase change temperature, high thermal conductivity and overcoming the problem of supercooling and phase separation, it has a wider application prospect in the field of construction.
