When it comes to central air system applications, the majority of system selections will require terminal unit applications that are in sync with the design intent.
This month, I’m going to examine some of the issues and concerns with the design, installation, commissioning, and operation of one such terminal unit application: VAV terminals. You might want to stop reading this column and pick up your 2019 ASHRAE Handbook, HVAC Applications, to refresh your knowledge of VAV design engineering by reading Chapter 48, Design and Application of Controls, as well as the 2020 Handbook, HVAC Systems, and Equipment, Chapter 4, Air Handling and Distribution.
