metal (copper in our coils). Figure 1 shows an outdoor condensing coil that was exposed to a severely contaminated environment. Note the copper tubes are intact but the aluminum fins are gone. This is the image and mechanism that most people think of when considering coil corrosion. In most failures of indoor coils, however, the copper tubes will have been penetrated while there
Copper Fin/Copper Tube (CuCu) Coils. For ultimate protection, particularly in salt-water atmospheres. While more expensive than standard aluminum fin coils, copper fin coils provide some unique advantages:Copper is generally stronger and more durable than Energy-Efficient Air Conditioning. Energy Efficiency and called the evaporator. The condenser, a hot outdoor coil, releases the collected heat outside. The evaporator and condenser coils are serpentine tubing surrounded by aluminum fins. This tubing is usually made of copper. A pump, called the compressor, moves a heat transfer fluid (or refrigerant) between the evaporator and the condenser.
Mar 23, 2021 · However, the vast majority of HVAC coils that you see are built with copper tubes and aluminum fins. That combination offers the most effective heat transfer at the most efficient cost. To begin, fins are responsible for a surprising 65% 70% of the heat transfer on any coil, while tubes are responsible for the remaining 30% 35%. Condenser coil for split-type air conditioner out-door Condenser coil of split-type air-conditioning system is an outdoor component. In wet climates such as Taiwan, the corrosion resistance of metal parts is the key to product reliability. The location of copper pipe welding is the most fragile part.
