Top 10 Light Commercial Economizer/Fresh-Air System Applications

Before we get into the top 10 light commercial HVAC economizer applications, let’s talk about why this list matters. Light commercial buildings are among the most common applications for economizers or fresh air systems. That means that installing economizers opens up new opportunities for contractors in these light commercial settings. Fresh air systems can help with many different comfort issues in these buildings. Our economizer, the Arzel® CoolMizer, is compatible with package units and split systems, so it provides even more opportunities for adding an economizer to a light commercial HVAC system.

Here are the top 10 light commercial economizer applications:

  1. Restaurants
  2. Salons
  3. Office Building
  4. Conference rooms
  5. Computer rooms/server room
  6. Athletic clubs/gyms
  7. Retailers
  8. Banquet rooms
  9. Daycare/School
  10. Churches

Why HVAC economizers work well with crowds

These applications create unique challenges when trying to keep an acceptable comfort level while maintaining a healthy IAQ. Office buildings, churches, conference rooms, and banquet rooms often experience increased temperatures when large groups of people gather in one place. These crowded spaces experience heat gains in these rooms regardless of the outdoor temperature.

Using the outdoor air to cool these areas in milder weather will save the building owner money and keep the occupants comfortable while maintaining temperature in other spaces, therefore not over-conditioning. That’s exactly what the CoolMizer does.

How light commercial economizers cool computer equipment

Computer and server rooms have significant heat gains year-round due to the heat given off by the equipment in the room. Using an economizer to cool this space when the outdoor conditions are favorable will save the business owner money and reduce the wear and tear on the outdoor unit while increasing system efficiency and reducing costs.

Reducing odors and indoor chemicals with fresh air systems

Salons, athletic clubs, restaurants, and daycares also benefit from the fresh air intake function. Bringing in a small amount of fresh air helps increase air circulation and eliminates the odors and chemicals associated with these establishments. In the case of daycares, open windows for ventilation are not always an option due to safety and security risks.

CoolMizer® Economizer


CoolMizer light commercial economizer applications

The Arzel CoolMizer is ideal for all of these applications, and its configuration is simple, with an easy-to-read LCD and setup wizard. It can also be integrated with the Arzel® Zoning system for more customized control of the airflow. Or, install it as a stand-alone economizer.

The CoolMizer operates with two separate dampers, one large for free conditioning and one smaller for ventilation, or the patented Arzel Damper2 technology. Damper2 technology is the only dual-purpose damper designed to provide both the benefits of free air conditioning and ventilation.

This innovative damper is two dampers in one, each controlled individually as required. Schedule a free webinar to learn more about the installation and setup of the Arzel CoolMizer.

Why economizers are the light commercial solution

Light commercial applications can be a challenge to keep comfortable affordably. Add-on heating and cooling solutions like economizers, fresh-air systems, and HVAC zoning enable businesses to customize the space to fit their needs while keeping employees and customers comfortable.

It allows you to provide clients with an economical, relatively unobtrusive solution, maximizing your value to the client while adding to your bottom line.
