Aluminum Coated Fin

(OP)
My friends i need to know about aluminum coated fin
which is using in the airconditioning minisplit system in the
evaporator or condenser
if you know any sites pl tell me
thanks

RE: Aluminum Coated Fin

Simsim, I don't know of any sites offhand, but aluminum fins are common on standard copper coils, probably due to their excellent ability to conduct heat, low cost to manufacture, and corrosion compatability with copper... Best I can recommend after that is a web search for "cooling coil design." -CB

RE: Aluminum Coated Fin

Dear ChasBean1,
thanks for your help, i want to know why they use
aluminum coated fin instead of aluminum fin in mini
split high wall unit
thanks osama  

RE: Aluminum Coated Fin

Simsim, the trend is to use coated fins on condensers. This is to prevent corrosion of the fins due to exposure to the athmosphere. particularly if the athmosphere is corrosive 9close to industrial exhausts) or exposure to saline air 9close to sea coast etc). Normally evaporator coils are not coated in airconditioning, since the coils is always having saturated air. Not really needed. Coated coils are expensive.

VEEKRISH thanks, but as i knew they must use this type of aluminum coated fin in the evaporator for high wall mini split units due to contact angle of water condensat on the fin so the water will not spread to air coming out from the indoor unit, thanks
