HVAC – Ventilation and Exhaust Systems

Course Description:

Outdoor air that flows through a building, either unintentionally as infiltration or intentionally as ventilation, is important for two reasons:

• Outdoor air is usually used to dilute indoor air contaminants.
• Energy associated with heating or cooling outdoor air is a significant space-conditioning load.

Buildings use this air movement in three different modes for air exchange:

• Forced-air ventilation
• Natural ventilation
• Infiltration.

These modes affect air quality, energy, and thermal comfort very differently. They also have different capabilities in maintaining a desired air exchange rate. All three modes should be included in the air exchange rate in a building at any given time. In this course we will discuss these various issues. 

Learning Objectives:

Upon successful completion of this course, participants will be able to:

• Understand the air handling units
• Know the different types of systems
• Understand the duct design and construction
