Fill in the blanks in the following problem set. To get credit, you must show all of your labor. Make sure to write properly and cleanly. Keep close eye on the units and crucial figures. Upload the spreadsheet(s) you want to use.
1) Calculating air change and ventilation rates: In the summer of 2020, a research team conducted tracer gas studies in a number of rooms. CO2 was injected from a portable tank to raise CO2 concentrations in the test room, and then the CO2 concentrations were allowed to decay back to background levels in each test. We took CO2 readings both inside and outside the room at the same time. During the tracer experiments, the tested rooms were left empty. The results of one such test conducted in a room in a room are supplied as indoor and outdoor CO2 data. Estimate the air change rate in the classroom under the tested conditions using this data (CO2 data). Show your work, including the graph (or any other approach) you used to calculate the AER. Give your answer in inverted hours (1/h) units. Calculate the effective outdoor air flow rate (in CFM) based on these experiments, assuming a floor size of 576 square feet and a ceiling height of 12 feet.
2) Assessing air purification technology
The market for air purification technology is exploding. Several firms are promoting their air cleaning solutions as effective at preventing COVID-19 transmission in interior areas. The marketing statements are frequently strong and sound very promising:
ABC technology destroys SARS-CoV-2 on surfaces and in the air by using reactive molecules [or super oxides or positive and negative ions]!
The FDA has just awarded XYZ technology emergency approval!
In just 60 minutes, DEF technology lowers viable SARS-CoV-2 [or surrogate organism] by 99.99 percent! You’ve been tasked with assessing the efficacy of one of these technologies from Aerus, which recently hired Deborah Birx, the former White House Coronavirus Coordinator during the Trump administration, to help promote sales of their ActivePure® technology, which claims to kill a variety of pathogens including SARS-CoV2: https://www.activepure.com/scientific-proof/ . A collection of test reports (active pure testing dossier) was submitted with this assignment by the manufacturer’s sales representative. Translate their MS2 bacteriophage test results from a log-reduction shown on their website (i.e., 99.9999 percent reduction after 60 minutes) to an equivalent clean air delivery rate using the first report in that packet (I. Aerosol Research and Engineering Laboratories testing of their Medical Guardian product) (CADR). How does this CADR compare to a regular HEPA-filtered portable air cleaner? Comment on any strengths and weaknesses you find in these test reports.
