High Efficiency And Safety Temperature Control Building Solid
Liquid Phase Variable Energy Storage Materials
Heat storage mechanism and characteristics:
- Phase change materials have the ability to change their physical
state within a certain temperature range.
- In the case of solid-liquid phase transformation, when heated to
melting temperature, a phase transition from solid to liquid
occurs. During the melting process, the PCM absorbs and stores a
large amount of latent heat. When the phase change material is
cooled, the stored heat must be lost to the environment within a
certain temperature range, and the reverse phase transition from
liquid to solid is carried out.
- During these two phase transitions, the energy stored or released
is called latent heat of the phase transition. When the physical
state changes, the temperature of the material itself remains
almost constant until the phase transition is complete, forming a
wide temperature platform. Although the temperature is constant,
the latent heat absorbed or released is considerable.
Types of building phase change energy storage materials:
1. Organic phase change materials
- It mainly includes paraffin, fatty acids and their esters.
2. Inorganic phase change materials
- Common are inorganic hydrated salts, such as sodium sulfate hydrate
and calcium chloride hydrate.
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.
Advantages of building phase change energy storage materials:
1. Energy saving and consumption reduction
2. Temperature adjustment and comfort improvement
3. Good compatibility with building structure
4. Environmental sustainability
5. Safe and non-toxic
