Instant Temperature Regulation Wizard - Breakthrough To Improve Building Heat Efficiency: Building Energy Storage PCM

Production Infomation:

• Phase change materials (PCM) are substances with high heat of fusion that melt and solidify at a certain temperature and can store and release a large amount of energy.

• When a material changes from solid to liquid, heat is absorbed or released, and vice versa. Therefore, phase change materials are classified as latent heat storage (LHS) units.

• Phase change energy storage material that can maintain a constant temperature for 8 to 10 hours.

• Phase change materials look like flocculent snow, with a certain degree of flexibility, easy to plastic.

• It overcomes the cooling, phase separation (precipitation) and other problems of traditional phase change materials, and is suitable for energy-saving buildings, household hot and cold MATS, ice MATS, thermal insulation bags in the medical and health care field, buried tunnel insulation, tatami MATS, camping equipment, etc.

Properties of phase change materials:

-- Physical properties
1. Status changes

• Depending on the type of phase transition, there is a mutual conversion between solid and liquid (common solid-liquid phase change materials) or between different solid (solid-solid phase change materials).

• For example, paraffin-like phase change materials change from solid to liquid when the temperature increases above the phase change temperature, and from liquid to solid when the temperature decreases.

2. Volume change

• During the phase transition process, the volume of the material may undergo a certain change.

• For example, crystalline hydrated salt phase change materials may expand and contract in volume due to crystallization and dissolution of hydrated salt during phase change.

-- Chemical properties
1.Stability

• Under certain temperature and environmental conditions, phase-change energy storage materials have good chemical stability and are not easy to decompose, oxidation and other chemical reactions.

• However, some organic phase change materials may be affected by oxygen in the air, ultraviolet light and other factors in the long-term use of aging.

2. Non-corrosive

• Building is a place for human activities for a long time, so building energy storage phase change materials are required to be non-corrosive.

• Most organic phase change materials are less corrosive to building materials, which is conducive to their use in combination with building materials, and will not cause damage to the building structure.

Product market trends:

• Demand growth is strong, and with the increasing global focus on energy efficiency and sustainability, there is a growing need for energy efficiency in the building industry.

• Building energy consumption accounts for a relatively large proportion of total social energy consumption, and building energy storage phase change materials can effectively regulate indoor temperature and reduce energy consumption such as air conditioning and heating, so it has great application potential in new buildings and existing building transformation.

• For example, in some large commercial buildings and public buildings, the use of phase change materials can significantly reduce energy costs and improve energy efficiency.
