Free Webinar: Air Systems Design (3 Part Series), August 18 - 20, 9:30 am - 12:30 pm PT
Event Description

This seminar is intended for engineers who design and/or commission HVAC air distribution systems. It includes a discussion of popular HVAC systems followed by detailed techniques for designing and sizing ductwork, selecting and sizing fans, selecting and laying out diffusers, sizing and ducting variable air volume (VAV) boxes, and selecting coils and filters.

Part one of this series starts with a brief introduction of fundamentals of thermal comfort and the fundamentals of indoor air quality and associated ventilation requirements. Detailed descriptions and schematics of the current popular HVAC systems, air distribution fluid flow fundamentals, ductwork fabrication, and ductwork sizing and layout will be discussed.

Agenda:

  • Thermal comfort
  • Ventilation code requirements
  • Most popular HVAC systems currently in use
  • Less popular HVAC systems currently in use
  • Duct types and fabrication
  • Pressure drop from ducts and fittings
  • Duct design methods
  • Return air plenum design

Learning Objective:

  • Understand fundamentals of thermal comfort
  • Understand the fundamentals of indoor air quality and determining minimum ventilation rates
  • Understand how the most popular HVAC systems work
  • Learn how ductwork is fabricated and how that affects duct design
  • Learn detailed techniques for sizing ductwork including VAV duct mains
  • Learn how to design plenum return air systems

Part two of the series starts with a discussion of noise and vibration fundamentals followed by a detailed discussion of fan types and fan selection.

Agenda:

  • Fundamentals of sound
  • Noise criteria (NC) and room criteria (RC) curves and recommendations
  • Vibration isolation
  • Pressure drop fundamentals and fan ratings
  • Fan laws, fan curves, and fan efficiency
  • Fan types and characteristics
  • Fan example applications
  • Variable air volume (VAV) fan performance

Learning Objective:

  • Understand the fundamentals of noise and vibration and how that impacts duct design and fan selection
  • Understand pressure drop fundamentals such as total, static, and velocity pressure
  • Learn about fan types and their applications
  • Learn how to use fan selection software to select fans

Part three of the series discusses room air distribution fundamentals and how to select and lay out diffusers and return air grilles, followed by a detailed discussion of how variable air volume (VAV) boxes work and how they are sized. Finally, air handler components, such as coils and filters, are discussed along with selection recommendations.

Agenda:

  • Air distribution fundamentals
  • Diffuser types and selection
  • Fire and fire/smoke dampers
  • Selecting VAV boxes
  • Air filtration fundamentals
  • Filter types and efficiency
  • Selecting coils

Learning Objective:

  • Understand room air distribution fundamentals
  • Learn how to select the type and size of diffusers
  • Learn how to lay out diffusers
  • Learn how VAV boxes work and how to size them
  • Learn how to select cooling coils
  • Understand the fundamentals of particle removal and selection of air filter type and efficiency
