The 25°C Phase Change Material Has A High Energy Storage Density And A Near-Constant Phase Change Temperature

The 25°C Phase Change Material Has A High Energy Storage Density And A Near-Constant Phase Change Temperature

Basic attributes:
1. Phase change temperature

• 25 °C phase change material changes from solid to liquid or vice versa at about 25 °C.

2. Enthalpy of phase change

• This material can absorb or release a large amount of latent heat during the phase transformation process, and the specific value depends on the type and composition of the material.

3. Density

• The density of most phase change materials is between 0.7 and 1.5 grams per milliliter, and the specific value needs to be determined according to the type of material.

4. Classification

• Phase change materials can be divided into two categories: organic (such as paraffin) and inorganic (such as crystalline hydrate salts), each with different physical and chemical properties.

Fields of application:
1. Solar energy system

• The use of 25°C phase change materials to absorb solar energy during the day and release it at night to improve energy efficiency.

2. Building energy saving

• Integrate phase change materials into building materials, naturally regulate indoor temperature, reduce the use of air conditioning and heating, and achieve energy saving.

3. Air conditioning and cold storage system

• During the off-peak power consumption period, the phase change material stores the cold energy generated by the air conditioning system, and releases it during peak hours, reducing the power load and improving energy efficiency.

4. Medical preservation

• In the process of transportation of medical devices and biological products, the cold storage capacity of phase change materials is used to maintain a low temperature environment to ensure the safety and effectiveness of products.

Special features:
1. Supercooling and phase separation

• Some organic phase change materials do not have the problem of supercooling and phase separation, and their performance is stable and more reliable in practical applications.

2. Thermal conductivity

• Although PCMs have high latent heat storage capacity, they generally have low thermal conductivity, which may limit their application in situations where rapid heat transfer is required.

3. Shape stability and durability

• New phase change materials are being developed to improve thermal conductivity, shape stability, and durability, which are essential for long-term use and increasing charge-discharge rates.

4. Enhanced heat transfer technology

• In order to improve the heat transfer efficiency of phase change materials, researchers have explored a variety of enhanced heat transfer technologies, such as adding fins, nanoparticles, or using external fields and rotation.

The status quo of the industry:
1. R&D and production

• Many companies focus on the R&D and production of phase change materials, providing high-purity phase change materials to meet different needs, and have passed ISO 9001 certification.

2. Wide application

• The products of these companies are widely used in energy-saving buildings, cold chain transportation, heat storage and other fields, promoting the commercialization and large-scale application of phase change materials.

Trends:
1. Composite phase change material

• In view of the problem that simple phase change materials are easy to leak, researchers prepare composite phase change materials through porous material adsorption or microcapsule encapsulation technology to improve the stability and application range of the materials.

2. Research on low-temperature phase change energy storage materials

• The academic community has conducted in-depth research on low-temperature phase change energy storage materials, including the basic characteristics of materials, classification, and applications in temperature regulation and heat storage.

3. Future prospects

• The future development direction includes improving the thermal conductivity of phase change materials, extending the service life, reducing costs and expanding new application fields.
