PRF Steel Duct Systems
Industrial Duct Systems
Ducts are passages used in heating, ventilation, and air conditioning (HVAC) to deliver and remove air. The needed airflows include, for example, supply air, return air, and exhaust air. Ducts commonly also deliver ventilation air as part of the supply air. As such, air ducts are one method of ensuring acceptable indoor air quality as well as thermal comfort. A duct system is also called ductwork. Planning (laying out), sizing, optimizing, detailing, and finding the pressure losses through a duct system is called duct design.
Here at PRF, we do our own ductwork and duct design in-house.
Duct Design
Process design of exhaust system will include
- Identification of contaminants, their density and size
- Deciding of air flow
- Sizing of the ductwork
- Calculation of resistance
- Finalizing the capacity of blower, etc.
The goal is to keep contaminants out using minimum airflow. It is estimated that increase in an inch of static pressure can add a few thousands of dollars to the operation cost per annum.
