Most conventional air handlers built decades ago face current challenges when it comes to upgrading and retrofitting. Almost all problems cannot be resolved in one strike, as they encompass old buildings, mechanical rooms, or heritage sites with old structures and designs.
Air Mixer – Post Pandemic Air Quality
Many of the air handling units (AHUs) installed in these spaces suffer from old age, outdated technology, and years of neglect or inadequate maintenance. In almost all cases, energy consumption soars, units become noisy, and issues such as condensation or coil freeze-ups arise, resulting in poor performance and thermal inefficiency due to improper mixing.
The Need of Energy efficient Air Mixer for Retrofit AHU
In older AHUs, the tight inlet plenum space ahead of the coils prevents proper mixing of outside and return air in the chamber.
As a result, there is a non-uniform gradient of air when it comes into contact with the heat transfer coil, leading to freeze-ups in winter and condensation in summer.
Moreover, the sheet metal bottom plates and channels in most existing AHUs often rust severely, causing water to trickle down above the ceiling and creating further havoc.
Given the common challenges faced at such sites, how does one mitigate existing mixing issues on a limited budget without the headache of complete replacements?
In some critical applications, replacing the air handler with a prolonged shutdown is not possible unless supplementary cooling or heating is added, which poses another challenge.
EB Air Mixer offers a unique solution to such instances. In fact, many EB Air Mixers are installed in existing AHUs to resolve common problems experienced during cold months, particularly for outdoor installations in extreme climates. EB Air has successfully addressed numerous issues with existing AHUs.
Furthermore, since EB Air mixing boxes are custom-built, they can be designed for any site, even with limited space or restricted access to existing AHUs.
It’s important to note that with the spike in energy costs, there is even more reason to reduce operating costs through proper mixed air, eliminating the need for supplementary heat and unnecessary maintenance.
