A Complete Guide to Choosing the Right DOAS System for Your Building

Air distribution plays a massive role within commercial buildings, often resulting in many challenges. From poor pressure and airflow control to supply and exhaust grille locations that are not placed according to the human thermal comfort zone, it can make for a stressful environment to work in.

To eliminate the hassle of dealing with these issues, you need to choose an air distribution system capable of delivering true comfort. One popular solution for airflow in commercial buildings is single-zone direct outdoor air systems (DOAS).

DOAS is a dedicated outdoor air system that uses mechanical means to bring fresh air straight from outside your building into an occupied zone inside.

The following article will inform you of the thing you need to know before installing a DOAS system

1. Identify The Main Function Of The System

Before deciding upon any air distribution system, you must define what you are trying to achieve by installing one. Determining the specific purpose of your air conditioning system will allow you to maximize its usability and effectiveness.

2. Determine Whether You Need Supply Or Exhaust Air

To decide whether to use supply or exhaust air, answer this one question: “Does your facility require ventilation in addition to cooling throughout the year?” If so, then you will want to go with an exhaust system. Only select a supply air system if your facility only requires cooling.

3. Look For The Features That Are Essential To You

Once you have established what purpose an outdoor air system will serve within your building, it is time to see which additional features would be beneficial for fulfilling your needs. Once again, make sure that anything you consider adding is necessary for achieving comfort.

4. Find Out How Effective The System Will Be

The effectiveness of DOAS systems is determined by many factors, including airflow control and where grilles are placed. For example, when appropriately used, ventilation in occupied spaces above +10C is possible during the winter months. There is a temperature difference indoors and outdoors that allows for the infiltration of cold outside air.

5. Consider All Maintenance Requirements

Any time a system requires a particular type of filter, it will increase how often you need to maintain it by adding more steps to the process. While this may not seem like much, cleaning the wrong type or number of filters can lead to problems resulting in system malfunctions. 

Start Your Journey To True Comfort with DOAS System

A dedicated outdoor air system offers heating, ventilation, and air conditioning to your space. This can be very beneficial if you live in an enclosed area without proper airflow.

DOAS is also highly energy-efficient compared to other types of Air conditioning systems. These systems can also act as dehumidifiers and prevent the growth of molds. Now that you know what outdoor air system is suitable for your building, it’s time to turn your attention to other details. It includes how an infiltration system can contribute towards excellent ventilation and whether or not there are any extra steps you should be thinking about.
