Summary

Air-handling unit controllers commonly use sequencing logic to determine the most economic way to use the components of the air-handling unit to maintain the supply air temperature at a setpoint value. The objective of the paper is to introduce the finite state machine sequencing control strategy for air-handling units and to compare this strategy with a traditional split-range sequencing control strategy. Simulation results demonstrate that in comparison to the split-range control strategy, the finite state machine control strategy leads to more stable operation of the air-handling unit when the feedback controller(s) used to control the supply air temperature is (are) poorly tuned.
