Classification and application of aluminium foil for air conditioners

At present, air conditioners are gradually developing in the direction of miniaturisation, high efficiency and high life expectancy. In the 1980s, the thickness of heat exchangers was 0.15-0.2mm, while today they are only 0.09-0.15mm thick. In addition, in order to improve the life of the air conditioner, reduce power consumption, improve the quality of ventilation and improve the cooling effect, and successively developed a variety of functions of the coated heat exchanger, typical of anti-corrosion heat exchanger, surface hydrophilic performance heat exchanger, surface hydrophobic performance heat exchanger, as well as anti-mould heat exchanger and self-lubricating heat exchanger.

Classification of aluminium foil for air conditioning.

1、Non-coated aluminium foil

Non-coated aluminium foil refers to aluminium foil that has been rolled and annealed without any form of treatment on the surface. The aluminium foil used for air conditioner heat exchangers in China 10 years ago and abroad about 15 years ago was uncoated aluminium foil. Even at present, about 50% of the heat exchangers used in developed countries abroad are still uncoated aluminium foil, while in China, the ratio is around 60%.

2、Coated aluminium foil

The so-called coated aluminium foil is a surface reprocessing of non-coated aluminium foil to give it a special function. In countries such as Japan and Germany, where technology is developing rapidly, coated aluminium foil has been used for more than 15 years. In China, on the other hand, coated aluminium foil has been used for no more than 10 years.
