❓ Frequently Asked Questions
Q
What is air conditioning aluminum foil and what are its other names?
Air conditioning aluminum foil is a thin aluminum material used in HVAC systems for heat exchange. It is also commonly referred to 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 provides basic heat exchange performance. Hydrophilic aluminum foil is coated with a special layer that improves water-spreading ability, anti-corrosion, and anti-fogging performance, making it the most widely used type in modern air conditioning systems.
Q
What thickness of aluminum foil is recommended for air conditioning systems?
For most air conditioning applications, a thickness of 0.09–0.11 mm hydrophilic blue or green foil is the most recommended. The general thickness range is 0.07 mm to 0.15 mm, with widths from 100 mm to 1200 mm depending on the system requirements.
Q
Where is air conditioning aluminum foil used in HVAC systems?
It is primarily used in evaporators and condensers as heat sinks to improve heat exchange efficiency. It is also applied in air conditioning duct systems to reduce energy loss during air flow, as well as in radiator fins, refrigeration heat exchangers, and other HVAC cooling components.
Q
What are the key technical indicators used to evaluate coated aluminum foil quality?
For coated aluminum foil, quality evaluation includes all indicators of uncoated foil (chemical composition, tensile strength, elongation, cupping value) plus additional parameters such as plate shape, coating thickness, coating adhesion, hydrophilic performance, and corrosion resistance.
Q
What is the market growth trend for air conditioning aluminum foil globally?
Global demand for air conditioning aluminum foil is growing steadily at an 8% CAGR from 2024 to 2030, driven by HVAC expansion, energy efficiency upgrades, and aluminum-for-copper substitution. Asia-Pacific leads the market, with China recording the fastest growth at 12.3% CAGR.
