How do VAV systems handle varying zone loads and occupancy patterns?

VAV systems are designed to handle varying zone loads and occupancy patterns through the use of zone thermostats, occupancy sensors, and scheduling algorithms. Zone thermostats provide real-time feedback on zone temperature, while occupancy sensors detect the presence or absence of occupants. This information is used to adjust airflow to each zone, increasing or decreasing airflow as needed to maintain a comfortable indoor environment. Scheduling algorithms can also be used to anticipate changes in occupancy patterns and adjust airflow accordingly, ensuring that the VAV system operates efficiently and effectively.
