Displacement Ventilation Systems

COURSE NO: M02-003
Displacement Ventilation Systems
Course Highlights

This online engineering PDH course describes the principles and practical applications of displacement ventilation and dedicated outdoor air systems for commercial buildings.  The student will gain an understanding of the energy and cost related to using these two types of systems.


Conventional heating, ventilation and air-conditioning systems in commercial buildings meet both outdoor air ventilation and space conditioning requirements using air distribution approaches that provide a mixture of outdoor air and recirculated air with the goal of achieving good air mixing within the occupied space. More recently, advanced ventilation approaches have been proposed, and in some cases installed, that separate the outdoor air ventilation and space conditioning functions (dedicated outdoor air systems) or that distribute air to achieve thermal stratification within the space.


This 2 PDH online course is applicable to mechanical engineers, design and construction personnel, technical staff and facility personnel who are interested in gaining a better understanding of displacement ventilation and dedicated outdoor air systems.
