HVAC

HVAC means heating, ventilation and air conditioning: the systems that manage temperature, airflow, humidity and, in some designs, filtration within a building. Equipment may include air handling units, chillers, heat pumps, ducts, controls and sensors with separate maintenance needs. A thermostat reading does not represent every occupied zone, and comfort does not by itself prove adequate air quality. Design and operation should consider occupancy, loads, outside conditions, zoning, maintenance, alarms and safe access. Building-management integration can improve visibility but also introduces network and control dependencies. Set-points must reflect applicable requirements and the real use of the space. Validation uses calibrated measurements across relevant locations and operating modes. Energy efficiency, comfort, preservation of equipment and ventilation can involve trade-offs that require monitored adjustment.
