Converting Constant Volume, Multizone Air Handling Systems to Energy Efficient Variable Air Volume Multizone Systems

Abstract

A low-cost technique to retrofit a constant volume multizone system to a more energy efficient variable volume system was demonstrated on five systems at Fort Bragg, NC, and the U.S. Army Engineer Research and Development Center-Construction Engineering Research Laboratory (ERDC-CERL) in Champaign, IL. When starting with a constant volume multizone air handler with modern Direct Digital Controls (DDCs), the conversion requires programming changes to the control strategy executed by the control system as well as the installation of an Air Flow Measurement Array (AFMA) and Variable Frequency Drives (VFD)s for the supply and return fans (if so equipped). A key feature of this approach is that the physical system is only minimally affected and except for the location at which the AFMA is installed, the ductwork is not modified.
