Why is hydrophobic aluminum foil used in air-conditioning bad performance?
You say the problem is not to consider the specific forms of aluminum foil, aluminum foil is if the plane form or the interval between two pieces of large enough water will decline because of gravity, but the structure of the air conditioning radiator and condenser cheating is too intense, because the water contact area is large enough, a resistance is greater than the weight of aluminum foil hanging in between jam, air circulation, and water on the hydrophilic foil due to stronger affinity, will flow along the surface, the formation water is not easy.
Hydrophobic aluminum foil above the water, the water will always hang on the foil, relatively speaking, reducing the air flow between the aluminum foil, so that the heat exchange rate decreased. Therefore, the air-conditioning is used "hydrophilic foil", as soon as there is condensed water flow away, does not affect or as little as possible affect the heat exchange rate.
Not "hydrophobic aluminum foil" is "hydrophilic foil", home air-conditioning generally use new water aluminum foil, said with "hydrophilic foil" is not good, is to deceive you. "Hydrophilic foil" flow better
