Safe Non-Toxic Phase Change Energy Storage Materials For Buildings In Line With Environmental Values

Material introduction:

Phase change thermal storage is a high-tech energy storage technology based on phase change materials. Thermal storage technology is an important technology to improve energy utilization efficiency and protect the environment. It can be used to solve the contradiction between thermal energy supply and demand mismatch. Electric power "shifting peaks and filling valleys", waste heat and waste heat recovery and utilization, as well as energy saving in industrial and civil buildings and air conditioners have broad application prospects. Compared with traditional water storage, due to the high heat storage capacity of phase change materials, Therefore, the design can save space in a narrow temperature range.

Material features/advantages:

• High latent heat of phase transition
• Stable performance, cycle times > 10000 times
• Wide phase transition temperature and low cost
• non-corrosive

How do phase change materials work?

• When the ambient temperature is raised to the phase change temperature of a phase change material, the material will change from a low-energy phase state (usually solid) to a high-energy phase state (usually liquid). This process requires the absorption of a large amount of heat, which is called the latent heat of phase transition.
• For example, in the process of changing from ice (solid) to water (liquid), the ice needs to absorb heat in order to melt, and this heat does not raise the temperature, but is used to change the state of the substance.
• In contrast, when the ambient temperature drops and the phase change material transitions from liquid to solid, it releases the latent heat of the phase change that was previously absorbed. This absorption and release of heat can regulate the temperature of the surrounding environment.
