HVAC duct design software with CFD from SimScaleĬFD, or virtual fluid flow simulation has become one of the most widely used practices among engineers. Yet, with the increased complexity of modern day industrial factories and plants as well as awareness of environmentally friendly alternatives, these methods have reached their limits. Historically, simplified analytical models and simplistic calculations were used to predict everything from the flow profile to the pressure drop of ductwork. One tool that expedites this process while remaining a cost-friendly alternative to traditional prototyping is computational fluid dynamics, or CFD, which allows HVAC professionals to test the performance of their ductwork systems online. Fume extraction, ventilation, and other ductwork vents must be designed and finalized in compliance with regulations, while also considering efficiency and eco-friendly material alternatives. In both residential and industrial settings, maintaining the health and well-being of building inhabitants is the most significant consideration. Many industries are facing this fume extraction issue, including pharmaceuticals, chemical processing, welding, paint spraying, and so on. Exposing workers to dust, toxic fumes, vapors, and other occupational hazards can cause serious adverse health effects, such as carbon monoxide poisoning. Compared to residential HVAC duct design parameters, industrial ductwork systems have more critical and specialized needs as the threat of toxic air and safety hazards are more present. The aforementioned guide covers the various standards needed for residential HVAC design, but isn’t fully holistic as it doesn’t satisfy industrial duct design demands. While ACCA aims to outline and comply with residential regulation, industrial buildings must consider additional factors. The image below outlines some of the guidelines based on the required CFM (cubic feet per minute) for systems up to 60 feet from unit to register: ACCA Duct Design Guide ( Source) In order to design a duct system, HVAC system designers must first complete a room-by-room Manual J load calculation as well as a Manual S equipment selection. The ACCA Manual D (last updated in 2016) entails the specifications for contractors to design residential ducts for different volume and zoned variable air volume (VAV) systems, along with the accepted range of duct construction materials to use.
In the United States, the Air Conditioning Contractors of America ( ACCA) is an ANSI-recognized national standard for residential HVAC duct design. When designing a duct system, standards can vary from country to country.
