Depending on the material, appearance and use, different types of air ducts have their own specific strong points and weaknesses.
When selecting an air duct, be sure to, first, consider such issues as the area weather conditions, duct location, application of the desired space, execution speed and the cost price, and then select one type or a combination of air ducts.
Types of air ducts (conventional):
- Galvanized (round and flat)
- Pre-insulated (PIR)
- Round Textile duct
In a building, if air conditioning equipment is the heart, air ducts would be its circulation system because they bring cold/warm/fresh air inside and send indoor air outside. To achieve this important task, we need, besides selecting the proper duct type, to design and execute the work through correct and precise engineering/technical computations.
The Pars Nasim Sahra Service Dept. Air Duct Design Team has tried, using specialized resources with scientific and practical experiences, to present the best solution and design methods to achieve highly efficient air-conditioning systems.
Some air duct design tips:
- Creativity in finding proper paths
- Scientific computation of the duct dimensions/divisions based on a space requirements
- pay attention to Reduced noise in different spaces
- Duct design and space architecture conformity
- Proper and uniform ventilation in all spaces
Pre-insulated (PIR) ducts Advantages Energy saving Very low thermal conductivity Soundproof and vibration-free Fire resistant Resistant to climate changes (+80°C to -50°) Environment friendly
Advantages Very high installation speed Size variety Flexibility in building curves and angles Reduced energy loss due to insulation Capable of tolerating temperatures from -20
Flat galvanized ducts Galvanized air ducts are the first generation of their type made in two models; flange type (English) and sliding type (American). The
