Task 7 ObjectivesOverall – Design, construct, and shakedown two

air cleaning “device” test loops compliant with (existing/emerging) industry acceptable method of testing and performance rating for filtration and UVGI in heavily cofunded effort.UIC ASHRAE 52.2/145.2 Test LoopPenn State ASHRAE 52.2/ARTI UVGI Test LoopTest Protocols and ShakedownBenchmark Air Cleaner Tests

Task 7 MethodologyOverall – UIC lead coordinated coverage of building

sectors, air cleaning technologies, and methods of performance testing in three campus effort.Task 7 Commercial/Institutional Sector Focus

• UIC testing of particulate and gas phase devices• PSU testing of particulate and UVGI devices• “constant source” standard compliant testing loops• “less defined” UVGI testing approach confronts PSU

Task 8 Residential Sector Focus• SU testing of portable and in-duct devices• “pull down” standard testing in environmental chambers

Task 7 UIC and PSU Test Loop DesignTest loop modules

• “wheel in and out” test & other section modules

• Quick clamp gasketedmodule connections

• Ease of cleaningstainless steel“arms length”

• Viewing ports• Sampling ports
