In principle, microalgae-based modules can be engineered to interact with air streams, but HVAC integration is materially different from placing a standalone photobioreactor in a room. It requires testing for pressure drop, moisture control, bio-containment, lighting, temperature, cleaning, safety and long-term reliability.
No. HVAC manages thermal comfort, ventilation and often filtration. OceanTree is a biological system and should be positioned as complementary. Any direct integration with HVAC should be treated as a separately engineered product with its own validation.
Microalgae can consume CO2 biologically, but an AHU application requires sufficient contact, light and residence time without compromising airflow or hygiene. The feasibility must be demonstrated through controlled engineering tests before commercial performance claims are made.
Immobilized microalgae are cells retained within a supporting matrix, such as a hydrogel, rather than freely suspended in bulk liquid. This can simplify handling in some applications, but mass transfer, light penetration, moisture, viability, contamination and mechanical durability become key design variables.
They are a research and engineering pathway, not a universally proven drop-in solution. A commercial design would need to demonstrate gas transfer, biological activity, humidity control, pressure drop, lifespan, cleaning, safety and reproducibility under real airflow conditions.
Key challenges include keeping the culture biologically active, delivering light, controlling moisture, avoiding contamination or aerosolization, maintaining acceptable pressure drop, enabling cleaning and replacement, and proving long-term performance. These are engineering validation questions, not just biological questions.
Conceptually possible modules require careful engineering because split AC systems have limited space and tightly controlled airflow. Any such product should be treated as development-stage until it passes safety, performance, maintenance and durability testing.
An AHU offers more integration space than a split AC, but commercial use still requires engineering around airflow, pressure drop, condensation, access, lighting and hygiene. A controlled test rig is the appropriate first step before site deployment.
Begin with a bench or duct test rig that records airflow, inlet/outlet CO2, temperature, humidity, pressure drop, biological viability, energy use and maintenance behaviour. Only after repeatable results should the design progress to an occupied-building test.
Share agreed non-confidential technical requirements first, then exchange deeper design information under an appropriate NDA and commercial development framework. Define IP ownership, test responsibilities, data rights, milestones, costs and commercialization terms before substantial R&D work begins.
