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.
