: A Comprehensive Guide to Air Handling Unit PartsAir handling unit (AHU) is an essential component of any HVAC system that is used to regulate air quality and temperature in commercial and industrial buildings. AHU has several parts, from fans and filters to heaters and chillers. Understanding the various components of AHU is crucial for selecting the right equipment, maintaining it, and troubleshooting any issues that arise. In this blog, we will provide a comprehensive guide to AHU components.1. Fans: Fans are used in AHUs to circulate air throughout the building. Typically, fans are of two types: centrifugal and axial. Centrifugal fans can move more air at higher pressures, whereas axial fans operate at lower pressures and are suitable for low airflow applications.2. Filters: Filters are used to remove impurities, such as dust and allergens, from the air passing through the AHU. Common types of filters used in AHUs are pre-filters, which capture larger particles, and HEPA filters, which remove smaller particles.3. Coils: Coils are used to heat or cool the air passing through the AHU. There are two types of coils: heating coils and cooling coils. Heating coils use hot water or steam to heat the air, whereas cooling coils use chilled water or refrigerant to cool the air.4. Humidifiers and dehumidifiers: Humidifiers and dehumidifiers are used to add or remove moisture from the air passing through the AHU. Humidifiers are used in dry climates to add moisture to the air, whereas dehumidifiers are used in humid climates to remove moisture from the air.5. Dampers: Dampers are used to regulate the airflow through the AHU. They can be manual or automated, and are typically made of metal or rubber.6. Sensors and controls: Sensors and controls are used to monitor and regulate the temperature, humidity, and air quality inside the building. They can be connected to a building management system (BMS) for centralized control.7. Pumps: Pumps are used in AHUs to circulate water or other fluids through the system. Grundfos supplies circulator pumps and end-suction single-stage pumps, which are included in air handling unit parts for the distributed pumping system.In summary, AHU components play a crucial role in regulating air quality and temperature in commercial and industrial buildings. Understanding the different parts of AHU is crucial for selecting the right equipment, maintaining it, and troubleshooting any issues that arise. Grundfos supplies AHU components, such as circulator pumps and end-suction single-stage pumps, for the distributed pumping system.
