15°C PCM: The Exceptional Phase Change Agent That Transitions Within A 15°C Temperature Band, Efficiently Absorbing Or Releasing A Substantial Quantity Of Latent Heat For Optimal Thermal Regulation

Product Description:

• This kind of material exchanges heat with the environment during the phase transformation process, so as to achieve the purpose of controlling temperature and energy utilization, and has the advantages of high energy storage density and small size compared with sensible heat energy storage. 15°C PCMs are particularly suitable for indoor temperature regulation and energy saving, such as in buildings, where they can absorb heat during the day to keep the room cool, and release heat at night to keep the room warm, thereby reducing the use of air conditioning and heating and reducing energy consumption.
• 15°C PCMs can include some inorganic salt hydrates, such as sodium sulfate decahydrate (Na2SO4·10H2O) and calcium chloride hexahydrate (CaCl2·6H2O). These materials have a high latent heat storage capacity, but they can also suffer from certain performance degradation issues, such as phase separation. Therefore, researchers have been looking for more stable and efficient phase change materials.

Performance metrics:

1. Phase change temperature

• Definition and importance: Phase change temperature refers to the temperature range of a phase change material as it transitions from one state of matter to another. For 15°C PCMs, this temperature is very close to the temperature range of human comfort, so it can be widely used in indoor temperature regulation and energy saving fields. Precise control of the phase change temperature contributes to more detailed and efficient temperature management.
• Test and evaluation: The most commonly used methods for testing phase change temperature are DSC (differential scanning calorimetry) and T-History method. These methods can accurately measure the temperature change of a material during the phase transition process to evaluate its effect in practical applications.

2. Heat storage

• Definition and Importance: Heat storage refers to the amount of heat that a phase change material can absorb or release during a phase change. Proper heat storage is the key to ensure the effect of phase change materials, which is directly related to the application effect of materials in temperature control, such as maintaining indoor temperature stability.
• Testing and Evaluation: Heat storage is usually tested using methods such as comparative and direct measurements. These test methods can help determine the ability of a material to absorb or release heat during phase transitions, which is critical when designing a temperature control system.

3. Thermal conductivity

• Definition and importance: Thermal conductivity is a measure of the heat conduction efficiency of a material, and for phase change materials, high thermal conductivity can speed up the transfer and distribution of heat, thereby improving the response speed and efficiency of the material.
• Testing and Evaluation: Thermal conductivity testing can be performed by a device based on the steady-state heat flux method, as recommended by ASTM C1784. Through measurement, the thermal conductivity of phase change materials in different states can be evaluated, which is of great significance for optimizing the application of materials and improving the design of thermal management systems.

4. Stability

• Definition and importance: Stability refers to the ability of a phase change material to maintain its thermal properties (e.g., phase change temperature, heat storage, etc.) after multiple phase change cycles. The high stability of phase change materials can ensure that they can still lose their temperature control ability after long-term use, which is very important for practical applications.
• Testing and Evaluation: Stability tests are usually evaluated by multiple phase transition cycle tests, such as RAL-GZ 896 and ASTM C1784 standard test methods, which include requirements for cyclic stability. Through these tests, the reliability of the material's performance over the course of long-term use can be ensured.

Scope of application:

1. Building energy saving

• 15°C phase change materials can be integrated into building walls, such as gypsum board, wall panels and concrete components, etc., to help regulate indoor temperature and reduce the use of air conditioning and heating. This application significantly reduces the energy consumption of buildings and increases occupant comfort.

2. Electric heating

• Compared with traditional electric heaters, 15°C phase change regenerative electric heaters use this material to store electrical energy to achieve continuous heating without repeated power-on, thereby saving energy and reducing electricity costs. Floor heating systems can also be made with phase change materials to store heat during periods of low electricity prices at night and release it during the day, optimizing energy use and saving money.

3. Clothing

• Clothing made of fibers implanted with 15°C phase change material can maintain the wearer's comfortable body temperature at different ambient temperatures. This garment can effectively regulate the temperature and improve comfort in either cold or hot environments.

4. Refrigeration equipment

• The use of 15°C phase change materials in refrigerated trucks and cold storage can replace the traditional compressor refrigeration method, save a lot of electrical energy, and reduce environmental pollution. PCMs are also used in the design of new air conditioning systems to reduce electricity consumption by storing outdoor low-temperature air energy and releasing it when needed.

5. Power peak shaving

• The application of 15°C phase change materials in power peak shaving can help the power grid release stored energy during peak demand hours and absorb energy during low demand troughs. This energy storage device plays an important role in balancing the load on the grid and improving energy efficiency.
