2.2 Introduction to AHU Supply Air Temperature and Pressure Resets

This is course 2.2 of the Common Advanced Control Strategies module.

Air handling unit (AHU) supply air static pressure and temperature resets are advanced control strategies that can save significant building energy in partial load conditions and are required by energy codes. In this presentation, we will introduce the AHU pressure and temperature reset concepts, describe different implementation options, and recommended AHU static pressure reset control setup. Industry best practices on implementing these resets will also be introduced. Detailed AHU static pressure reset control sequences using the “Trim and Respond” method will be illustrated through animation and a control programming example. Finally, common issues related to the strategy setup, operation, and maintenance will be discussed.
