What is a Small Air Handling Unit?

If you’re in the HVAC industry, you’re likely familiar with the concept of an air handling unit (AHU). But what exactly is a small air handling unit? Small air handling units are specially designed for businesses or buildings that require controlled temperature and humidity levels. They are typically used in places where space is limited, such as office buildings or retail stores. In this article, we will discuss the different types of small AHUs and their various features and benefits. We will also take a look at how these units can help improve energy efficiency and indoor air quality.

What is a Small Air Handling Unit?

A small air handling unit, or AHU, is a device used to circulate and condition air in a space. The most common type of AHU is a central air conditioner, which is used to cool and dehumidify indoor air. Other types of AHUs include heat pumps, furnaces, and ventilators.

AHUs are classified by their airflow capacity, which is measured in cubic feet per minute (cfm). Central air conditioners typically have an airflow capacity of 400 to 1,200 cfm. Heat pumps and furnaces have an airflow capacity of 1,500 to 3,000 cfm. Ventilators have an airflow capacity of 4,000 to 6,000 cfm.

The size of the space that an AHU will be used in will dictate the type and size of AHU that is required. Small spaces may only require a single room air conditioner or a small window-mounted unit. Larger spaces may require multiple units or a central system. The climate conditions of the space will also dictate the type of AHU needed.

The Different Types of Small Air Handling Units

There are four different types of small air handling units: the packaged terminal air conditioner, the self-contained air conditioner, the split system air conditioner, and the ductless mini-split air conditioner.

The most common type of small air handling unit is the packaged terminal air conditioner (PTAC). PTACs are typically used in hotels, motels, and office buildings. They are also commonly used in residential applications such as apartments, condos, and townhomes. PTACs are available in a variety of sizes and capacities to meet the needs of any space.

The second type of small air handling unit is the self-contained air conditioner (SCAC). SCACs are similar to PTACs in that they are also available in a variety of sizes and capacities. However, SCACs do not require ductwork for installation. This makes them ideal for spaces where ductwork is not possible or practical. SCACs are often used in commercial applications such as retail stores, restaurants, and warehouses.

The third type of small air handling unit is the split system air conditioner (SSAC). SSACs are similar to PTACs and SCACs in that they come in a variety of sizes and capacities. However, SSACs differ from PTACs and SCACs in that they use two units: an indoor unit and an outdoor unit. The indoor unit contains the evaporator coil while the outdoor

Pros and Cons of a Small Air Handling Unit

When it comes to deciding whether or not to install a small air handling unit (AHU), there are a few factors to consider. Here we will take a look at the pros and cons of installing a small AHU in your home or business.

PRO: Less expensive than a larger AHU
One of the main reasons people choose to go with a small AHU is because they are less expensive than their larger counterparts. This savings can be significant, making small AHUs a great choice for budget-conscious shoppers.

CON: Lower capacity
Although small AHUs cost less, they also have lower capacities. This means that they may not be able to meet the needs of a large home or business. If you have a lot of space to heat or cool, you may need to look at other options.

What to Look for When Buying a Small Air Handling Unit

When shopping for a small air handling unit, it is important to consider the specific needs of your space. What are the dimensions of the room? What is the climate like? How much airflow do you need?

The size of the room will dictate the size of the unit you need. If you have a large space, you will need a unit with more horsepower. The climate will also affect your decision. If you live in a hot, humid climate, you will need a unit that can handle those conditions.

Finally, consider how much airflow you need. This is determined by the number of people in the space and the amount of activity taking place. If you have a small space with few people, you won’t need as much airflow as a larger space with more people.

How to Install a Small Air Handling Unit

There are many types of small air handling units (AHU), and the installation process will vary depending on the unit you have. However, there are some general tips that will help you through the process.

1. Read the manufacturer’s instructions carefully before beginning any work. This will ensure that you understand the specific requirements for your unit.

2. Most small AHUs can be mounted on a wall or ceiling. Choose a location that is out of the way of foot traffic and away from any heat sources.

3. Once you have chosen a location, mark the mounting holes with a pencil or pen. Drill pilot holes at these marks, then use appropriate screws or bolts to secure the unit in place.

4. The next step is to connect the power supply to the unit. Follow the manufacturer’s instructions for this, as different units will have different requirements.

5. Finally, connect the ductwork to the unit according to the manufacturer’s instructions. Make sure all connections are tight and secure before turning on the unit.

Conclusion

Small air handling units are a great option for those looking to efficiently regulate their indoor air quality. They come in a variety of sizes and styles, making them suitable for many different applications and needs. With energy-saving features like variable speed motors, these small AHUs can keep your space comfortable while also saving you money on energy costs. Investing in one of these efficient systems is sure to be beneficial in the long run.
