An air handling unit (AHU) is a vital component of HVAC systems used in facilities management. It plays a crucial role in maintaining indoor air quality and regulating the temperature and humidity levels within a building. To understand how AHU units function, it’s essential to know their components.
1. Filters: These are responsible for removing dust, dirt, allergens, and other pollutants from the incoming air before it enters the space. Regular filter replacements or cleanings are necessary to ensure optimal performance.
2. Heating and cooling coils: AHUs have both heating and coolcooling coils that help control the temperature of the conditioned air. The heated or chilled water passes through these coils, transferring heat energy to achieve the desired indoor climate.
3. Fans: AHUs utilize fans to circulate air throughout the system. These fans can be either centrifugal or axial depending on specific requirements.
4 . Dampers: Dampers regulate airflow by adjusting openings within ductwork connected to an AHU unit. They allow for precise control over ventilation rates in different areas of a building.
5 . Humidifiers/dehumidifiers: In environments where humidity control is necessary, AHUs may include humidifiers or dehumidifiers as part of their design.
6 . Control panel: The control panel contains sensors, actuators, and a controller that monitor and adjust various parameters like temperature, humidity levels, fan speed etc., ensuring efficient operation of the AHU unit.
Understanding these components helps facility managers make informed decisions when it comes to maintenance or troubleshooting issues with their AHU units.
Types of AHU Units and Their Uses
Types of AHU Units and Their Uses
AHU units come in various types, each designed to serve specific purposes in HVAC systems. Let’s take a closer look at some common AHU unit types and their uses.
1. Single Zone AHUs: These units are ideal for smaller spaces with consistent temperature requirements, such as individual offices or small rooms. They provide precise control over heating and cooling, ensuring optimal comfort.
2. Multi-Zone AHUs: As the name suggests, these units are capable of serving multiple zones simultaneously. They allow for different temperature settings in separate areas within a facility, making them suitable for larger buildings with varying climate needs.
3.
VAV (Variable Air Volume) AHUs: VAV systems adjust the amount of conditioned air delivered based on demand. By regulating airflow through dampers or variable fan speeds, they offer energy efficiency while maintaining desired temperatures across different zones.
4.
Static Pressure Control AHUs: These units focus on maintaining a specific static pressure level within ductwork to ensure balanced airflow throughout the building. They are commonly used in facilities where consistent air distribution is critical.
5.
Rooftop Package Units: Designed for outdoor installation, rooftop package units combine all necessary components into one compact system. They are commonly used in commercial buildings where space constraints indoors make rooftop placement more practical.
Understanding these different types of AHU units helps facility managers select the most appropriate option based on their specific requirements and budget considerations.
