Commercial Air Conditioning Ductwork Design

Typically made of galvanized steel, HVAC ductwork is made to transfer air which may be a cool air supply, return air or exhaust air. HVAC ductwork design includes planning (pipe layout), pipe sizing and HVAC detailing with pressure loss. The design for the ductwork follows the buildings' floor plan which includes the fire walls and direction joists. Good HVAC ductwork design is always concerned about increasing the effectiveness of air distribution.

There are many details that need to be considered before and during commercial air conditioning installation that need professional attention and handling. Especially when installing central air conditioning on a larger and more complex scale there is a lot to consider. A HVAC contractor can provide a comprehensive plan for commercial air conditioning ductwork design and a range on different air conditioning systems available for installation.


A good commercial ac contractor can easily do all the tasks required. As a business owner you need to stay focused on meeting your business demands and leave the specifications for your buildings airflow to a qualified HVAC contractor. A commercial HVAC contractor will also be able to inform you of the most efficient, most cost effective and durable type of units for your building's needs. They can also provide advice on how the right installation can help to lower utility bills. Be sure to ask for written estimates and for the length of time required for the installation process. You want to make sure to avoid discomfort and inconvenience for your customers and employees.

A well designed and installed commercial air conditioning system eventually results in a better work environment and greater productivity. Comfortable temperatures and better air quality reduces dust and pollutants. A temperate environment can extend the life of operating equipment. It all can be contributed to well designed and installed HVAC ductwork along with proper vents which help the central airconditioning system to equally distribute the chilled air in all parts of the building.

Commercial Air Conditioning - Cooling Solutions For Work Spaces

If your work space is full of heat generating electrical and electronics, then you definitely need some heat removal system to save yourself and your equipments. Air conditioning is one way of doing it. In an industrial set up, proper heating, ventilation or air conditioning (HVAC) is essential to ensure that the work environment is safe for other employees and workers.

Which places need industrial or commercial air conditioning?

Places where large number of people and heat generating equipments are employed need air conditioning to remove heat and circulate fresh air and remove the stuffy gases out.

Example: Hospitals, IT companies, manufacturing factories, hotels, etc.

Types of Industrial and Commercial Air Conditioning

Modern systems use ductless or split air conditioning. The cooling unit and condenser are located far away from the room on roof tops usually. The cooling is thermostat controlled. Ducted cooling system is not used these days due to inefficiency.

Apart from that many different cooling technologies are available, such as air cooling, water cooling, glycol cooling and chilled water cooling.

Air cooled systems

Widely used for its convenient ductless set up and easy maintenance.
There is a condenser unit outside which helps in exchanging the fresh air and removing the hot air inside.
But the cooling pipes cannot run very long distances. Hence, the height between the work space and the roof or outside environment can be a constraint.


Glycol cooled systems

This is a much sophisticated cooling system in which temperatures below 50ºF (10ºC) can be achieved.
Glycol is the coolant used. These can run for long distances and can provide cooling for multiple work spaces with a single condenser unit.
But, quality and quantity of glycol should be optimum and hence need more maintenance.


Water cooled system

Water is cooled inside a cooling tower which in turn is relayed back to the heat exchanger placed in the work environment.
Multiple work spaces can be cooled with a single cooling tower.
But, maintenance of cooling tower and optimum quality of water required can pose economic set back.


Chilled water system

This has a greater heat removing capacity.
One chiller plant is required and it can cool an entire building.
Can be used for larger areas with greatest efficiency.
But installation charges are sky high and the system removes lots of moisture from the air which might cause problems for employees.


Depending upon your requirements, you can choose among these discussed cooling systems to cool and ventilate your work space. Some of them can be worked in combination with each other as a single system doesn't work in all environments. Choose wisely and make your work space employee friendly.
