chilled water air handling unit
A chilled water air handling unit (CWAHU) represents a sophisticated HVAC solution that combines precise temperature control with efficient air distribution. This system utilizes chilled water as its primary cooling medium, circulating it through cooling coils to remove heat from the incoming air stream. The unit consists of several key components, including a fan system, cooling coils, filters, and dampers, all working in harmony to deliver conditioned air throughout a building. The CWAHU draws in outdoor air, mixing it with return air from the building, then passes this mixture through filters to remove contaminants. The filtered air then flows across the chilled water coils, where heat exchange occurs, cooling and dehumidifying the air before it's distributed through the ductwork. These units are particularly valued in commercial and industrial applications where consistent temperature control and superior air quality are essential. Modern CWAHUs incorporate advanced control systems that allow for precise adjustment of temperature, humidity, and airflow rates, making them ideal for environments with specific climate requirements. The versatility of these systems enables them to handle various cooling loads while maintaining energy efficiency through modulating capacity control.
