  Introduction • An airhandling unit is a device that regulates and circulates air as part of a heating, ventilating, and air-conditioning system • An AHU can improve the indoor air quality and comfort, as well as the energy efficiency of the HVAC system • An AHU can be used for different applications, such as large buildings, clean rooms, laboratories, etc. 1
• 3.
  Components • An AHUconsists of various components, such as fan, filter, coil, silencer, plenum, etc. 2 • The fan powers the air to expel it from the AHU to the ducts that distribute the air throughout the rooms • The filter removes particles, viruses, bacteria, odors, and other air pollutants from the air • The coil heats or cools the air by transferring temperature between coolant and air • The silencer reduces the sound level of the installation • The plenum homogenizes the air flow

  Types An AHU canbe classified based on factors such as size, location, configuration, airflow control, etc. 2 A small AHU that only includes an air filter, coil, and blower is called a terminal unit or a fan coil unit A large AHU that conditions 100% outside air and no recirculated air is called a makeup air unit or a fresh air handling unit An AHU that is designed for outdoor use, typically on roofs, is called a packaged unit or a rooftop unit

  Energy Efficienc y An AHU canreduce the energy consumption of the HVAC system by having heat recovery units that mix indoor and outdoor air in the exchanger This reduces the temperature contrast between the air and the coil, and therefore the climatic contribution and energy consumption An AHU can also use variable air volume control to adjust the airflow according to the demand This reduces the fan speed and power consumption when less airflow is needed

  Conclusion AN AHU ISA DEVICE THAT REGULATES AND CIRCULATES AIR AS PART OF AN HVAC SYSTEM AN AHU CAN IMPROVE THE INDOOR AIR QUALITY AND COMFORT, AS WELL AS THE ENERGY EFFICIENCY OF THE HVAC SYSTEM

  Answers • 1. Whatare the components of an air handling unit (AHU)? • - The components of an AHU are the fan, filter, coil, silencer, and plenum. • 2. How can an AHU improve indoor air quality and comfort? • - An AHU improves indoor air quality and comfort by filtering out pollutants and regulating the air circulation. • 3. What are the different types of AHUs based on their applications? • - AHUs have different types: terminal units (fan coil units), makeup air units (fresh air handling units), and packaged units (rooftop units).

  Answers • 4. Howdoes an AHU contribute to energy efficiency in an HVAC system? • - AHUs improve energy efficiency by using heat recovery units and variable air volume (VAV) control to reduce energy consumption. • 5. What is the purpose of a silencer in an air handling unit? • - The silencer in an AHU reduces noise levels for a quieter environment.
