Air Handler

An air handler which is also known as an air handling unit (AHU) is used to assist in circulating air while it is being heated, ventilated, or as part of a HVAC system. The air handler is often made up of a large metal container which has a number of important components within it. Some of the main parts within the air handler include the blower, heating elements, and filter chambers.

The air handler is designed to connect with the ducting system in a building. The system will circulate conditioned air through the ducting system of the building until it arrives back at the air handling unit. The small-sized air handlers may recirculate air but the larger models use only external air and do not recirculate any air at all. There are also some air handling units which are made to be used outside. These are often referred to as packaged units.

How the Air Handler Works
An air handling unit lets you have sufficient air circulation within your home or building. In combination with a HVAC system or a heat pump it could provide the appropriate air circulation for the building. To get a better understanding on how the air handler works just read about the processes that it must complete below.

Cooling
The very first thing that must be done is cooling the air. The air enters the air handler from outside and it will need to be cooled. There will be a coolant which is in the handler that is used to cool the air.

Distribution
After the fresh air is cooled off it can be circulated into the building. The blower in the air handler will help with this task. The blower helps push the cooled air through the ducting system in the building. All the rooms in the building will have the cooled air distributed to it.

Exhaust
There will be other ducts that are used with the air handler besides the main ducting system. There are return ducts which are used for collecting and returning the exhaust air to the air handler. The exhaust air is warm until it reaches the air handler. At this point the air handler will extract the heat from the exhaust air. The heat will be sent outside and the refrigerant will go back into the air handler to help with cooling other air. The opposite of everything just mentioned is done when the air handler is used in the winter as the air must be heated as opposed to cooled off.

Where to Install an Air Handler
The location that you install the air handler will depend on the type of air handler you have and the specifics of your building. In most cases the air handling unit will be installed on the roof of your home. This is usually the best way to go about installing an air handler in regards to functionality. You may also want to consider installing an air handler in a room within the building if it is possible.

Air handlers are usually installed outside of the building for commercial use but inside the building for residential use. An air handler could still be installed inside a building for commercial use but it could cause a few complications such as noise and less spare room. For home use, you obviously would not want to install the air handler outside of your home as it is not an easy task and can be physically off setting for your home.

Choosing an Air Handling Unit
If you are looking to purchase an air handling unit then you will want to make sure of one thing in particular. You have to be sure that the air handling unit will be compatible with the outdoor compressor. There are some outdoor compressors which are used with only certain types of air handling units. Some of the outdoor compressors will be compatible with most or all air handling units though. Find this out ahead of time so you invest in an air handler that will work properly with your outdoor compressor.

You will also want to look at a few other things when choosing an air handling unit to invest in. Some of the important factors in a good air handler include the amount of noise it makes, the settings and features it includes, and how energy efficient it is.

The last thing which you should factor in would be the size of the unit. If you purchase an air handler which is not capable of cooling enough of the building then it could make the air in the building feel warmer than you may like. If you purchase an air handler which has too high of a cooling capacity for the building then it could end up costing more in electricity then you needed to pay. Therefore, make sure that you choose an air handler which is designed to work with your building perfectly.

An air handler is necessary in most buildings as it will keep the air in the building cool and at the right temperature. If you are shopping for an air handling unit then you may want to read up more on them before choosing a model to buy. There are many things to consider when choosing an air handler. This article has only touched the surface of what makes an air handler a worthwhile investment for your building. To close, if you are looking to buy an air handler then make sure that you read up more on air handling units and find out all you need to know before making an investment.
