The capacity of the HVAC system is typically designed for the extreme conditions. Most operation is

part load/off design as variables such as solar loads, occupancy, ambient temperatures, equipment &

lighting loads etc keep on changing through out the day. Deviation from design shall result in drastic

swings or imbalance since design capacity is greater than the actual load in most operating scenarios.

Without control system, the system will become unstable and HVAC would overheat or overcool

spaces.
