HVAC systems are not only about supplying conditioned air — they are about controlling it intelligently.
In this short video, the working principle of a VAV (Variable Air Volume) terminal unit is demonstrated.
The system continuously adjusts the airflow according to the actual requirements of the space through a motorized damper. When necessary, the reheat coil provides additional temperature control, while the thermostat and building control system manage the overall operation.
From an engineering and project management perspective, effective HVAC design and commissioning should focus on three key objectives:
• Occupant comfort
• Energy efficiency
• Reliable system control
Proper coordination between HVAC equipment, controls, BMS, commissioning and project ex*****on is essential to achieve the intended performance of a building.
Smart HVAC control is not simply about moving air — it is about delivering the right amount of air, at the right temperature, at the right time.
