Basics of heat-storage materials

There are three types of heat storage sensible, latent and chemical reaction heat storage. Latent heat storage is the most important way of storing heat, and is also called phase change heat storage . Latent heat-storage materials have been widely used for about 40 years. 

The US National Aeronautics and Space Administration (NASA) accelerated the application research of latent heat-storage materials for the space laboratory in the 1960s. They were used to improve the protection of instruments and astronauts against extreme fluctuations in temperature in 

Incorporated CO into liquid inside the hollow fibre. 2 When the liquid solidified and the solubility of the COj decreased, the diameter of fibre increased and the heat-insulating ability rose. 

Incorporation of polyethylene glycol (PEG) and 4 plastic crystal materials into hollow rayon or polypropylene fibre. 

Coated PEG on the surface of fabrics. The thermal 5 storage and release properties of the fabrics were reproducible after 150 heating and cooling cycles. Chemical Week and Wall Street Journal reviewed 6, 7 Vigo s research work.
