2 Acknowledges that HVAC systems play a role in the dissemination of diseases in buildings Key points: Infectious diseases can be transmitted via an airborne path Designers have a responsibility to minimize that potential Dilution ventilation Building pressure control Filtration Oxidative technologies,  UVGI, PCO ASHRAE Position Paper, June, 2009 2

3 Passive Oxidation 3

4  What is the Product?  How does the panel work?  Testing  Product Features  Design Considerations  Why they buy  Applications 4

5 What is the product? Photo Catalytic Oxidation Panel (produces oxidizing agent) First Glance: Filter with a light in it? 5

6 Not a Filter / Is a PCO Panel  Think it is a filter; we have plenty  It is a panel and we have nothing like this  Filter = Commodity  Panel = Technology  Filter = Everyone sells  Panel = Let us consider, More information needed 6

7 How does the panel work? Have you ever used hydrogen peroxide on a cut? Did it bubble and boil up? What was it doing? Destroying infection causing virus, bacteria and spores. Our panels create OH. We are trying to replicate the natural process the troposphere uses to clean the air we breathe. “Detergent of the atmosphere” Katja Riedel and Keith Lassey explain how OH, the hydroxyl radical, works to cleanse the atmosphere of harmful trace gases. “Introducing OH, the hydroxyl radical Although it makes up about a fifth of our atmosphere, oxygen (O 2 ) is not the main oxidant. Other molecules that are produced naturally in the atmosphere, including ozone (O 3 ), the nitrate radical (NO 3 ), and the hydroxyl radical (OH), are much more reactive, even if their atmospheric concentrations are low. Radicals are highly reactive because they have unpaired electrons which tend to transfer to other molecules. The OH radical is the most important oxidant in the troposphere, the lowest part of the atmosphere (below about 10 km). Nobel Prize winner Paul Crutzen coined the phrase “detergent of the atmosphere” to describe this important cleansing role of OH. Most of the trace gases found in the troposphere are oxidised by OH into water-soluble products that are washed out by rain and snow. Specifically, OH is responsible for oxidising carbon monoxide (CO) and other carbon-based molecules, such as methane (CH 4 ).” Water & Atmosphere 16(1) 2008 Caution: Two Types – Active (No people) Passive (Safe for Occupied Spaces) 7

8 Photocatalysis Process Redox reaction: A reaction in which electrons are transferred from a donor (the reducing agent) to an acceptor molecule (the oxidizing agent) 8

9 Testing / Does it Work? Extensive 3rd Party and Field Testing Sample results from 3rd party testing. (With no pre-filter) PCO shows a single pass reduction in microbial contaminants. 9

10 Expected Results: Lower levels of VOC’s and Bio-aerosols in the conditioned space 10

11 Residential Unit Single Panel Scalable / Easy Retrofit Product Features: Array of Panels Side or Front Load San Francisco Airport 11

12 AHU’s: Location – In Air Stream Preferred down stream of coil Advantages - Low pressure drop (.05@500fpm) Easy to Service (12,000hr lamp) Requires little space (6” panel) Low energy (Cost of ODA) Sustainable (15 year panel) One Device – Three Solutions Cleans Coil Reduces VOCs Destroys Bio aerosols 12

13  Design Goal (Global / At the Source)  Panels encompass the entire airstream in a rack (Location)  Collection & Type of Contaminates (Source & Concentration)  Destroys in the airstream within the panel (Residence time)  Does not broadcast agents into the occupied space Design Considerations: 13

14 Hospitals: Odors……. Heliports & Generators Surface Recharge Integrity of Design The O.R. no one will use State of the Art Schools: Average Daily Attendance Resistant Strains (T.B.) E.P.A. “Tools for Schools” Lost teaching days Complaints Airports: Odors Airborne pandemic Casinos: Smoke Money Rooms Employee health (Liability Issues) Animal Care: Kennel Cough Odors Airborne Viral Why they buy: 14
