Air Conditioning Ducting & Ducts Supplier

Air Conditioning Ducting & Ducts Supplier

Air conditioning ducting and ducts is a type of pipe or tunnel that is used to distribute air from the air conditioner throughout a structure or building. The systems of ducts known as ductwork, are the central component of a building’s heating, ventilation and air conditioning (HVAC) system. In most air conditioning systems, only one set of ductwork is present which is used to transport cool air in summer and heated air in winter as air is required for general ventilation needs. Ducting is used only with large central air conditioning units and is not required for homes or small offices that use split systems or ductless air conditioning.

Shapes & Sizes Of Air Conditioning Ducting & Ducts

Air conditioning ducting is selected based on size, shape and material. The size of a duct is based on air pressure in the home or office space, the type of HVAC equipment being used and the cooling needs of the occupants. Round ducts are considered to be the most efficient by allowing a greater volume of air movement per unit of duct but they are rarely used. Instead, building constructors and air conditioning installers prefer square or rectangular ducts which fit more easily into tight ceiling and wall cavities. Spiral ducting which resembles corrugated pipes is often chosen for its attractive appearance when the spiral ducts will be left exposed or painted to blend in with the environment.

Ducting Fabrication Materials

Different materials can be used to manufacture air conditioning ducts. Galvanized steel sheeting is the most widely used due to its strength, low cost and resistance to rust and corrosion. For special projects, stainless steel or aluminium can also be used.

Fabrication & Installation Of Air Conditioning Ducting & Ducts

Our sheet metal supplier has the equipment to fabricate all types of ducts and air conditioning equipment according to specification and architectural design. No ducting project is too big or too small, we install in small office blocks to large shopping complexes, hospitals, hotels etc. The services of our mechanical engineers specialising in air conditioning are always available to assist our customers in designing complete air conditioning systems.

Air Conditioning Ducting & Ducts For Central Air Conditioner Systems

To understand the need for air conditioning ducting, one must first understand how a central air system works. First, a system of intake grilles or louvers pulls fresh air from outside into the central air conditioner. The air is then cooled and blown into an air conditioning duct system where it is distributed to various rooms and office spaces. The cool air enters the rooms through air terminal units installed at the end of each duct line which generally take the form of diffusers or grilles. This network of ducts that transport cool air from the air conditioning unit to each room is called the supply ductwork.

To regulate the air pressure in each room, some air must be removed to make way for the new cool air supply. A second set of air conditioning duct called the return ductwork, is used to remove and transport warmer air from each room back to the air conditioning unit for cooling. The air enters the return ducts through exhaust grilles or registers in each room, then travels back to the central air conditioning unit where it is cooled again for redistribution or released to the outside of the building and exchanged for fresh air.
