Annexair has unveiled a brand-new eco-friendly ventilation system: a Biocomposite central air unit made of recycled plastic water bottles!

The Biocomposite unit was unveiled during the Expo AHR in Orlando, Florida, and will be competitively priced on the HVAC market. This new product was thoughtfully designed in-house after seven years of R&D and provides many benefits to commercial building owners who care about the environment, for those who are planning on getting this system installed, then make sure you get some wire mesh to place as a filter on your new unit.

• Operating this unit would reduce the greenhouse gas effect by about 85% compared to conventional steel units;
• Not only is it 100% recyclable and good for the environment, this Biocomposite casing does not require any metal components;
• The Biocomposite resin is fire-resistant, has no impact on the environment nor on the human health;
• The Biocomposite casing consumes less energy, is sustainable and fully resistant to corrosion and rust;
• As the casing is 50% to 60% lighter than conventional units, it means less weight on building structures and during transportation;
• The unit should generally last 50 to 60 years, and even longer if well maintained;

“The year 2020 is pivotal for the Annexair team and also for our entire industry,” said François Lemieux, Annexair president. “We can no longer ignore the devastating effects of climate change. That’s why we believe in a renewed business model that can meet the requirements of the North American market.”

Solution

In order to house base building mechanical equipment to support laboratory space demands, the custom supply AHUs by Cambridgeport were provided with equipment vestibules to support base building mechanical needs.  The (2) large vestibules are housing the Konvekta energy recovery skid, main chilled water piping, energy recovery piping, expansion tanks, air separators, chilled water pumps and VFDs. By integrating the mechanical space into the rooftop custom AHU vestibules, the building is able to maximize the square footage for usable space.

Project Highlights

Konvekta:

• The Konvekta pumped glycol energy recovery system provides variable flow pumped glycol energy recovery between the 100% OA and 100% exhaust air-streams, treating 140,000 CFM of supply air and 140,000 CFM of exhaust air. The coils are manufactured specifically for efficiency and turn-down.  The system will be remotely monitored for performance and guarantees energy recovery performance to the owner.  When energy recovery alone is not enough to meet supply unit temp setpoint requirements, heat (one boiler installation is complete, via boiler hot water) is injected into the glycol ER loop via plate / frame heat exchangers enabling the energy recovery coil to provide both heating and energy recovery functionality. This means, no hot water coil required in the AHU or any branch HW piping to the AHUs.  Konvekta will provide reports to the owner on how the system performed for proof of performance.

Smardt: (2) 450-ton custom / oil free air-cooled chillers are on the roof.  These chillers include:

• (4) Magnetic bearing (Turbocor) compressors
• Integral free cooling and low ambient kit, down to -40°F ambient operation. When cold enough outside, the chillers provide cooling during winter months without the need to operate compressors.  This means no need for separate fluid coolers that require additional piping, controls and roof space.
• Low noise condenser fans with inlet and outlet attenuation
• Custom electrical layout: Dual points of power to provide flexibility in generator sizing during emergency scenarios. Free cooling and a portion of mechanical cooling will be available power outage to provide cooling needs to critical spaces at lower power consumption rates than single point of power would provide
• Industry leading efficiency, especially at part loads
• No oil!

Cambridgeport:

• Custom AHUs and large equipment vestibules
• EC fan arrays

MK Plastics:

• High plume dilution lab exhaust fans
• Direct drive, arrangement #4
• Motors are down low at roof level for ease of serviceability
• High nozzle velocities to create a safe plume which allows for a large range of fan turndown before needing any bypass air as per ANSI Z9.5. (3,000 FPM min velocity required).

Ingenia:

• Custom recirculation AHU serving a clean room for the biologics suite
• Custom feature included anti-microbial powder coat interior liner to provide the ultimate cleanliness, the unit served ceiling installed HEPA filtration

Carel:

• 21 HeaterSteam Titanium, atmospheric room by room humidifiers paired with UltimateSAM stainless steel dispersion tubes.  Served by RO water, these humidifiers are providing precision humidity control for critical applications with continuous modulation and high levels of reliability

Fan Arrays
One of the most significant innovations in air-handling unit design is the concept of using an array of small single-width, single inlet direct-drive plenum fans in lieu of the more conventional design that includes one or two large plenum or housed centrifugal fans. Fan arrays can be used for supply, return, and relief fan assemblies and they offer several significant advantages vs. conventional fan system designs:

• Reduced AHU length;
• Reduced sound power, especially on the discharge side;
• Improved redundancy;
• Reduced fan energy if sound attenuators or system effect are eliminated;
• Easier motor and fan replacement; and
• Easier to install in retrofit applications.

Disadvantages include higher (but ever falling) first costs and increased weight for the fan section. These are minor relative to the advantages.

Custom Air Handlers
Another significant change in the industry has been improved competitiveness of custom AHUs. Until recently, the cost premium for custom AHUs versus modular commercial AHUs was a factor of 5 or so. But improvements in manufacturing processes and lower labor rates in adjacent countries have caused the premium to be reduced to a factor of 1.5 or 2 from about 20,000 cfm (10 000 L/s) to 50,000 cfm (25 000 L/s). This premium can be offset by installation cost savings with the ability to make the AHU almost any desired dimension and aspect ratio and include any desired features. For AHUs above about 50,000 cfm (25 000 L/s), there is no cost premium for custom AHUs—this market sector is dominated by custom AHU manufacturers.

Mega-AHUs
The combination of fan arrays and affordable custom AHUs has also made it practical to design very large mega-AHUs. Our firm has designed several projects with AHUs in the 100,000 cfm (50 000 L/s) to 200,000 cfm (100 000 L/s) range serving large variable air volume (VAV) distribution systems. We have two high-rise office building projects in the design phase that have partially field-built VAV AHUs designed for 240,000 cfm (120 000 L/s) and 585,000 cfm (275 000 L/s), respectively.
