The Experimental Study of TiO2 Nano Compound Coating Applied in Air Conditioner

Article Preview

Abstract:

Experimental study was carried out with TiO2 Nano-sized compounds coated on aluminum foil to study the cleaning properties and heat transfer effect. The experiments were also carried out for air conditioners which fins of evaporator and condenser were coated with TiO2 nano compound coating. Results show that the foils with TiO2 nano compound coating presents better self-cleaning property and improved heat transfer effect. Air conditioner’s properties with TiO2 nano compound coating evaporator and condenser is higher than that without coating. The maximum heat capacity was found to be increased 8%. The nano-sized liquid showed better synthetic function such as excellent hydrophilic, better cohesion, water flushing resistance.
