Aluminum foil tape insulation principle, why insulation?
It has the functions of heat insulation, waterproof, moisture-proof and so on. Its solar radiation absorption coefficient is very low, which can insulate most of the heat transfer.
The air conditioner foil is a special material for the heat exchanger fin of an air conditioner, and an early air conditioner foil is a plain foil. In order to improve the surface properties of the plain foil, an anticorrosive inorganic coating and a hydrophilic organic coating are applied before forming to form hydrophilic foil. At present, hydrophilic foil accounts for 50% of the total amount of air conditioning foil, and its use ratio will be further improved. There is also a hydrophobic foil, so that the fin surface has hydrophobic function, prevent condensation water adhesion. Because of hydrophobic foil, the technology of improving surface defrosting needs to be studied further.
Aluminum foil itself is a good conductor of heat, wrapped directly on it, basically can not play a role in heat preservation, but also to accelerate the loss of heat, so when the use of wrapped inside some insulation cotton, and then wrapped in aluminum foil. Aluminum foil is actually the conduction of the external temperature, to protect the temperature inside from outside influence, in fact, is thermal insulation cotton.
