Functional analysis of color selection
The color of air conditioning aluminum foil is not merely for aesthetic purposes; it is closely related to the functionality of the coatings applied:
- Hydrophilic Coating (Blue): The blue aluminum foil features a hydrophilic coating that absorbs moisture, improving heat exchange efficiency. In high-humidity environments, the hydrophilic coating effectively prevents water droplet accumulation, reducing scale buildup on the heat exchange surface and enhancing the cooling performance of the air conditioning system.
- Corrosion-Resistant Coating (Gold): Gold aluminum foil is used to enhance the corrosion resistance of the foil, particularly in high-temperature or humid environments. The gold coating effectively resists corrosive substances such as moisture and salt in the air, extending the lifespan of the air conditioning system.
- Thermal Conductivity: While the color itself does not directly affect the thermal conductivity of aluminum foil, the choice of coating can influence heat exchange efficiency. Hydrophilic coatings can improve thermal conductivity, while corrosion-resistant coatings help maintain the cleanliness of the heat exchanger surface.
Why are Blue and Gold the most common?
Blue and gold aluminum foils are the most commonly found in the market due to their distinct functional advantages:
- Blue Aluminum Foil (Hydrophilic Coating): Due to the special properties of its hydrophilic coating, blue aluminum foil excels in improving heat exchange efficiency, making it particularly suitable for air conditioning systems that require frequent cooling. It effectively reduces moisture accumulation, keeping the heat exchanger clean and enhancing the overall efficiency of the air conditioning system.
