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 course is based on the document Initial Evaluation of Displacement Ventilation and Dedicated Outdoor Air Systems for U.S. Commercial Buildings – NISTIR7244
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
