Hydrophilic Aluminum Foil
Uages of Hydrophilic aluminium foil
Hydrophilic aluminum foils are the main raw material for household air-conditioning heat exchangers. It has a great influence on the efficiency of the air conditioner. If the raw material of the heat exchanger is hydrophilic aluminum foil, the cooling efficiency can be improved by 5%, and it also has the functions of anti-corrosion, anti-mildew, and odorless, and will not cause the accumulation of water droplets to affect heat transfer.
Because there are no water droplets, the noise caused by vibration is correspondingly reduced; the air-conditioning powder is prevented from being blown into the room, causing adverse effects on the human body, and meeting environmental protection requirements. Hydrophilic aluminum paper for air-conditioning should comply with YS/T95.2-2001.
