Air Handling Units

Air Handling Units, or AHUs, are devices that are used to condition and circulate air in buildings. They are an important part of any HVAC system, and they can be used to provide heating, cooling, ventilation, and dehumidification. AHUs are typically located in a central location within a building, and they use a variety of components to condition the air, such as fans, coils, and filters. The conditioned air is then distributed throughout the building via ductwork.

What are the benefits of using AHUs?

There are a number of benefits to using AHUs, including:

• Improved indoor air quality: AHUs can help to improve indoor air quality by removing pollutants from the air, such as dust, pollen, and bacteria. This can help to create a healthier and more comfortable environment for occupants.
• Increased energy efficiency: AHUs can help to increase energy efficiency by using energy-efficient components and by optimizing the way that air is conditioned and distributed throughout the building. This can lead to significant savings on energy costs.
• Reduced maintenance costs: AHUs can help to reduce maintenance costs by providing easy access to all of the components that need to be serviced. This makes it easier to keep the unit running smoothly and to prevent costly repairs.

What are the different types of AHUs?

There are a variety of different types of AHUs, each with its own unique features and benefits. Some of the most common types of AHUs include:

• Constant volume AHUs: Constant volume AHUs deliver a constant volume of air throughout the building, regardless of the load. This type of AHU is typically used in buildings with a relatively constant load, such as office buildings and schools.
• Variable volume AHUs: Variable volume AHUs deliver a variable volume of air throughout the building, based on the load. This type of AHU is typically used in buildings with a variable load, such as hospitals and shopping malls.
• Dual-duct AHUs: Dual-duct AHUs deliver two separate streams of air throughout the building, one stream of cold air and one stream of hot air. This type of AHU is typically used in buildings with a high demand for both heating and cooling, such as hospitals and hotels.

How are AHUs used in buildings?

AHUs are an important part of any HVAC system, and they play a vital role in providing heating, cooling, ventilation, and dehumidification. AHUs are typically located in a central location within a building, and they use a variety of components to condition the air, such as fans, coils, and filters. The conditioned air is then distributed throughout the building via ductwork.

What are the career opportunities for people with knowledge of AHUs?

There are a number of career opportunities for people with knowledge of AHUs. Some of the most common careers include:

• HVAC technician: HVAC technicians install, maintain, and repair HVAC systems, including AHUs. They typically have a background in electrical and mechanical engineering.
• HVAC engineer: HVAC engineers design and specify HVAC systems, including AHUs. They typically have a background in mechanical engineering.
• Building manager: Building managers are responsible for the operation and maintenance of buildings, including the HVAC systems. They typically have a background in business or engineering.

How can online courses help me learn about AHUs?

Online courses can be a great way to learn about AHUs. There are a number of different online courses available, from introductory courses to advanced courses. Online courses can provide you with the flexibility to learn at your own pace and on your own schedule. They can also provide you with access to a variety of resources, such as lecture videos, projects, assignments, quizzes, exams, discussions, and interactive labs. These resources can help you to engage with the material and to develop a more comprehensive understanding of AHUs.

Are online courses enough to fully understand AHUs?

Online courses can be a helpful learning tool, but they are not enough to fully understand AHUs. In order to fully understand AHUs, you will need to combine online learning with hands-on experience. This can be done by working with an HVAC technician or engineer, or by taking a course at a local community college or trade school.
