Ryan M. MacGillivray, M.Sc., P.Eng.

SUMMARY:       

This seminar will help develop an understanding of the basics of air movement; the components of air distribution systems; considerations of human comfort; load and occupancy demand; duct system design; sound and vibration; and how codes and standards affect the design of air systems. After completing the course, you should know:

• The functions of the components of an air distribution system, including major equipment types and auxiliary components.
• The principles of air distribution as they relate to human comfort.
• The principal codes and standards affecting air system design.
• How to layout and size a simple duct system and calculate pressure losses in the system.
• Common methods for reducing airborne sounds in systems and
• How to start an air system and diagnose common problems associated with air system start-up.

A copy of ASHRAE’s “Fundamentals of Air System Design” will be provided to all attendees. Continental breakfast and lunch will be provided.

COURSE CONTENT:

• Fundamentals of Air Flow - Static and dynamic compressible fluid (air) laws, friction effects, the friction chart, and density and altitude effects.
• Air Distribution System Components - System overview, air handling units, ducts, controls, air distribution devices, and sound absorbers.
• Human Comfort and Air Distribution - Principles of human comfort, principles of space air distribution, and types of air distribution devices.
• Relationship of Air Systems to Load and Occupancy Demands - Operating system selection criteria, system types by heating/cooling equipment type, system type by duct configuration, economizers and outdoor air intakes.
• Exhaust and Ventilation Systems - Design considerations, system types, and energy recovery.
• Air Movers and Fan Technology - Fan principles, fan drives, fan selection, fan installation design, fan controls and the effect of variable resistance devices.
• Duct System Design - Design overview, materials, construction, design and sizing, and sample systems.
• Codes and Standards - Building code requirements, ASHRAE Standard 90.1-2016, ASHRAE Standard 62.1-2016, other codes and standards, and sources of information.
• Air System Auxiliary Components - Dampers, air filters, humidifiers, duct heaters and duct insulation.
• Sound and Vibration in Fan Systems - Fundamentals of sound, sound and vibration sources, sound attenuation, and vibration control.
• Air System Start-Up and Diagnostics - Design considerations, air volumetric measurement methods, balancing procedures for air distribution systems, and noise and vibration diagnostics.
• An Actual Duct Design Problem - Duct design procedures, building and system, and working through the problem.

The firm specializes in mechanical system design for commercial and institutional buildings, including the Children’s Hospital of Saskatchewan, office buildings, nursing homes, and university buildings. Systems include building heating, ventilation, air conditioning (HVAC), controls, fire protection, plumbing, and medical gas. Prior to joining Daniels-Wingerak Engineering Ltd. in 2002, Ryan was a Research Assistant and Sessional Lecturer at the University of Saskatchewan, where he received his B.E and M.Sc. degrees in Mechanical Engineering in 1999 and 2005. He has been registered as a Professional Engineer in Saskatchewan since 2005, with Permission to Consult since 2011. Ryan is also a licensed to practice in Alberta with APEGA and maintains the corporate Permit to Practice as Responsible Member. Ryan has been active with the ASRHAE Saskatoon Board of Governors since 2003, including president in 2008-09. He is currently serving as the Saskatoon Chapter Membership Promotion Chair. In addition, Ryan was on the Region XI regional executive as Regional Vice-Chair (Research Promotion), and helped organize the 2016 Chapter’s Regional Conference as General Chair. Ryan is also currently the chair of the APEGS Professional Practice Exam Committee (which oversees the Law and Ethics Seminar), and serves on the Governance Board, and the Registrar’s Advisory Committee. Ryan and his wife, Margaret, have three school-aged children, and they all enjoy golf and camping.
