System dynamics and energy use
The goals of the project were to evaluate the importance of process dynamics in building HVAC systems. The specific objectives were: 1. To study the dynamics of a building HVAC system using test data and computer models; 2. To determine the effect of the time between control decisions on the energy consumption of an HVAC system; 3. To determine dynamic HVAC operating strategies that will potentially reduce energy consumption. The HVAC system of the 11 story IBM building in Atlanta, Georgia, was studied using a combination of data collected at the site and models of the components. The HVAC system consists of two 550 ton centrifugal chillers, a cooling tower with two cells and a two speed fan in each cell, and variable and constant air volume air distribution systems. An energy management and control system (EMCS) that monitors the flow rates, temperatures, and pressures throughout the system, controls the operating modes, and sets the status of major components was installed in the building.
