HVAC & Refrigeration systems don’t seem to be the identical. But aluminium is also becoming the tube material of choice in HVAC applications. Why?
1.Less expensive
2.It is much more abundant than copper
3.Lighter
4.Recyclable
You obtain a lighter device once you employ aluminium for both tubes and fins, as against copper tube and aluminium fin solutions. The all-aluminum system improves the current balance of the material, providing better corrosion resistance and less degradation of heat transfer performance during use. You furthermore may get more design flexibility with aluminium, and recycling is less complicated.
Aluminum duct could be a passageway fabricated from aluminum that mainly is employed to maneuver air, like with air con or heating systems, throughout a structure or building. Heating, ventilating, and air con (HVAC) ducts are typically manufactured from aluminum. Aluminum ducts also are used with home dryer systems; as aluminum doesn’t rust, this kind of duct is ideal for removing the nice and cozy, moist air.
The duct work can either be flexible or rigid, and sometimes fiberglass insulation is added for better thermal control.
The most common use of aluminum duct and fittings is that within the heating and air con industry. Flexible and rigid duct is commonly accustomed route conditioned air with a home or building. Aluminum duct is employed thanks to its high strength to weight ratio—a very lightweight section of rigid duct can be spanned large distances with no need to be supported.
The flexible form is employed due to aluminum’s ability to stretch; a versatile aluminum duct may be bent many times and still maintain an air tight cavity. Insulated varieties of both of those is accustomed minimize transfer of warmth between the contents and therefore the environment, making HVAC systems more efficient.
Since aluminum duct can either be rigid or flexible, installation is usually quite simple. Rigid units is supported by metal or plastic strapping attached to the structure itself, or they’ll be directly mounted to a surface using large brackets.
Flexible sections of duct is allowed to rest on an uneven surface, or hung using metal or plastic strapping. Since aluminum duct work maintains an airtight cavity, it doesn’t must be supported during a way that maintains a line of delivery.
