Optimal control of duct pressure in HVAC systems.

Author(s) : LI H., GANESH C., MUNOZ D. R.

Summary

The energy cost of monitoring and controlling a building environment is a serious consideration for the heating, ventilating and air-conditioning engineering industry. The work is focused on minimizing the energy cost associated with the control of variable-air-volume (VAV) systems. The authors modified a low-speed wind tunnel to simulate a single VAV system. Conventional proportional and integral (PI) control, adaptative control, and optimal control algorithms were developed and applied to the duct pressure control loop within the VAV system. A comparison of the performance of these control algorithms indicates than an optimal control strategy can save up to 30% of the energy consumed in a system that employs a conventional PI control scheme.
