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
