ATMOSAIR TESTING EFFECTS: Syracuse University Building Energy and Environmental Systems Laboratory

As our team strives to make the air we breathe as sustainable as possible, we continue to collaborate with universities that believe in sustainable, environmentally friendly buildings.  Syracuse University’s Center of Excellence originated in 1996 from visions that targeted regional collaborations in environmental and energy systems.  SyracuseCoE fully engages faculty, students and collaborators at 200+ firms and institutions to catalyze innovations that improve energy efficiency, environmental quality and resilience in healthy buildings and cleaner, greener communities.

Concentrating on clean and renewable energy, indoor environmental quality, and water resources, SyracuseCoE’s Innovation Ecosystem improves built and natural environments—the places in which we live, work, learn, and play.  

This past October 2018, AtmosAir tested its technology at Syracuse University’s Building Energy and Environmental Systems Laboratory, under the supervision of Dr. Jianshun Zhang, one of the world’s preeminent professors building environments and indoor air quality.  In addition to being an ASHRAE Fellow, Professor Zhang’s research ranges multi-scale BES from nano/micro-scale in porous media to buildings and urban environment, and involves engineering, architectural design, human health and performance.

The testing was performed on full-scale chamber tests to evaluate the technology’s performance for the removal of Volatile Organic Compounds (VOCs) under full-scale chamber conditions.  Two AtmosAir systems that were properly sized for the chamber volume were provided and tested in the tests. The units tested were set at maximum flow rate and ion output condition during each of the two tests conducted.

For each test, a mixture of 8 VOCs (hexane, 2-butanone, iso-butanol, toluene, hexanal, tetrachloroethylene, ethylbenze and decane) were vaporized in the chamber after the chamber had thermally stabilized at the test condition.  After the VOC concentrations reached the steady state initial level, the air cleaner placed inside the chamber was turned on, and the concentration decays of the VOCs were determined by sorbent tube sampling followed by thermal desorption and GC/MS analysis. The Clean Air Delivery Rate (CADR) was thus calculated for each VOC based on the measured concentration decay along with the measured concentration decay curves.

RESULTS:

The testing showed the AtmosAir Bipolar ion technology to be significantly effective on reducing VOC (Volatile Organic Compounds) which are gaseous contaminants that can degrade air quality and irritate occupants.  AtmosAir tested at over a 90% reduction rate on 8 common indoor VOCs, building on its proven, tested ability to significantly improve indoor air quality.
