❓ Frequently Asked Questions
Q
What is air conditioning aluminum foil and what are its common names?
Air conditioning aluminum foil is a thin aluminum material used in HVAC heat exchange components. It is also widely known as AC foil, HVAC aluminum foil, heat exchanger aluminum foil, fin stock aluminum foil, and condenser aluminum foil.
Q
What is the difference between plain aluminum foil and hydrophilic aluminum foil for air conditioners?
Plain aluminum foil has no surface coating and relies on its base mechanical properties. Hydrophilic aluminum foil features a special coating that improves anti-corrosion, anti-fogging, and water drainage performance, making it the most widely used type in modern air conditioning systems.
Q
What thickness and width are recommended for air conditioning aluminum foil?
Common thickness ranges from 0.07 mm to 0.15 mm, with standard widths of 100 mm to 1200 mm. For most air conditioning applications, a thickness of 0.09–0.11 mm hydrophilic blue or green foil is the most recommended for optimal heat transfer, durability, and cost efficiency.
Q
What are the key technical indicators for coated aluminum foil?
For coated aluminum foil, key technical indicators include all the mechanical performance indicators of uncoated foil (chemical composition, tensile strength, elongation, cupping value), plus plate shape, coating thickness, coating adhesion, hydrophilic performance, and corrosion resistance.
Q
How is air conditioning aluminum foil used in HVAC systems?
It is primarily used in evaporators and condensers as heat sink fins to enhance heat exchange efficiency. In cooling mode, it absorbs indoor heat and transfers it outdoors; in heating mode, it transfers outdoor heat indoors. It is also used in duct systems to minimize energy loss during airflow.
Q
What is the market growth trend for air conditioning aluminum foil?
Global demand is growing at a steady 8% CAGR from 2024 to 2030, fueled by HVAC market expansion, energy efficiency upgrades, and the substitution of copper with aluminum. Asia-Pacific is the leading region, with China experiencing the fastest growth at 12.3% CAGR.
