November Product Parade
Filtration & Ventilation
In September 2021, Daikin Applied introduced the upgraded Rebel Applied™ with enVerid Sorbent Ventilation Technology™ (SVT), reportedly the industry's first packaged total-air-quality system that combines the benefits of sorbent media with a class-leading, configurable rooftop unit.
Rebel Applied with SVT helps solve a variety of common IAQ issues in buildings. For example, when people breathe in oxygen, they exhale carbon dioxide (CO2). When numerous individuals occupy a classroom or workspace for several hours, CO2 levels rise steeply. This not only has a significant impact on air
quality, but can affect occupant health and performance. Off-gassing from furniture, building materials and the like also introduces volatile organic compounds (VOCs), such as formaldehyde, into the air.
Sources report that the integrated SVT system addresses these concerns by removing CO2, VOCs and other contaminants using sorbent filtration that captures pollutants while allowing oxygen and water to pass through freely, resulting in cleaner air.
Matthew Dodds, senior product manager for Daikin Applied, said there have been
feature enhancements in Rebel Applied regarding IAQ over the last couple of years given the current climate related to COVID.
"It seems like contractors are mostly focusing on how they can impact their retrofit and replacement businesses with IAQ," Dodds said. "Rebel Applied has a flexible cabinet and smaller footprint which gives contractors space to add IAQ features when they go to replace existing units. They’re able to grow the unit with IAQ features and still be able to fit it onto the existing roof curb. For example, maybe they would add extra high-efficiency filtration sections and UV lights. Those are the two most common features they’ve been adding.
"They can also add inverter compressors to improve IAQ, with precise temperature and humidity control, or add ventilation using energy recovery or sorbent ventilation technology."
Dodds said the adoption of sorbent ventilation technology is due to changes to ASHRAE Standard 62.1-2019 (addendum aa), which makes the application of air cleaning technologies like sorbent ventilation much simpler.

The Trane® Mixed Air Unit is one option for adding ventilation to a space. It's an outside air unit that offers fresh air for improved indoor air quality and energy efficiency for an end-user's budget. The unit delivers up to 100% fresh air into your building and meets the ventilation requirements specified in ASHRAE 62.1.The unit meets minimum EER and IEER efficiency standards.
Trane Commercial HVAC has engaged with Synexis® the developer of innovative Dry Hydrogen Peroxide (DHP) that fights different viruses, bacteria, mold, odors, and insects. DHP works continuously to reduce the levels of microbes in any type of facility from the air and on surfaces – without anyone having to leave the room.
"In schools, IAQ projects can involve rooftop units, or an applied system with air handlers and chillers. But there are also schools using VRF systems. there can be rooftop units. Indoor air quality initiatives are not necessarily streamed to specific types of equipment." James said.
"There's not a single solution that works for all customers in the same vertical market," added Florida-based Jeff Wiseman, indoor air quality portfolio leader for
Trane Commercial HVAC. "It's about understanding the current system capabilities and challenges they have. For example, a lot of schools in Florida have mold issues. So when looking at a solution, not only do you want to be effective on airborne viruses, but you also want something that can help with mold mitigation. Schools up north have a different challenge of how to get more outside air into the space and still keep it comfortable and within desired thresholds for humidity and other parameters." ASHRAE IAQ standards are also a guide as Trane offers solutions.
"Then, there are customers who are looking for a health and safety rating, trying to get well building certified. At that point, you get into digital connectivity and monitoring challenges. [The course of action] does very much depend on the customers' ultimate goals," James explained.

Alec Burmania, IAQ product manager for Lennox Commercial HVAC, said the company's commercial UVC germicidal lights were popular even prior to the COVID-19 pandemic.
"What is interesting about UV-C in the last year is the typical use case, or reason why a customer would want UV-C, has changed over the last few years,"
Burmania added that it's essential to have a way to verify IAQ efficacy and show flexibility in applications. "Two things important to customers are effectiveness of the product, especially with regard to virus elimination. Having clear data and claims around the customer benefits, but also, how it can be applied, and how can we sell it in our channel? For rooftop products, we offer factory- or field-installed kits, that make the product easy and safe to install. Those are two of the most important points."
Burmania said HVAC contractors understandably want installation guidelines. And for customers, when and how virus and mold elimination come into play, and what that means to customers and their building occupants.
"Questions sales persons often receive are mostly related to UV-C safety (protection from ozone), where it can be installed, and effectiveness," he said.
Burmania said school applications are most in demand at present.

Fans
Greenheck’s SQ mixed flow fan line, with a unique combination of high efficiency, low sound, and ease of installation in a square housing design now includes a new outdoor option along with additional accessories and sizes. The SQ mixed flow fan can now be specified for ducted horizontal-mount outdoor applications when
space constraints require a cost-effective rooftop-mounted unit. The outdoor option is base-mounted and includes a full cover over the unit to protect electrical components and prevent water entrapment.
New accessories include inlet and outlet guards to protect against intrusions; these guards remove easily for maintenance and inspection. The SQ mixed flow fan’s new filtration box provides a compact, clean air solution while eliminating the need for special remote filter box assemblies. A variety of washable aluminum, MERV-8 and MERV-13 filters are available.
