SUGGESTED TEST COMPLETING REQUIRED DATA COVID VIRUS TEST IN NON-TURBULENT HVAC FAN SUPPLY AIR CONSIDERING ESCALATED GLOBAL WARMING AND POSSIBLE VIRUS TRANSMISSION IMPACTS OUTSIDE AIR EXHAUST AIR AUTOMATIC DAMPERS D1 D2 D3 SUPPLY RETURN FAN FAN (TURBULENCE FOR VIRUS) (TURBULENCE FOR VIRUS) TO OTHER ROOMS FROM OTHER ROOMS SUPPLY DIFFUSER ROOM EXHAUST PLASTIC TENT AIR FLOW SURROUNDING (TYPICAL HOLE) DIFFUSSER HOLES TENT SEALED AT FLOOR (TYPICAL) AND CEILING WITH TAPE THE PROBLEM------ Increasing outdoor air ventilation is escalating global warming in two manners: -1- The increased heating required increases GHG emissions caused by the HVAC system up to about 700% -2- The increased exhaust air increases atmospheric heat input via the HVAC system up to about 670%. The only information we have found indicates that no testing has been done in all the appropriate locations on typical HVAC systems for live COVID virus, supporting the maximum ventilation position of much of governing society. Opinions expressed by authorities indicate that the virus cannot live through turbulent environments. The reports found indicate the live virus cannot travel through the typical HVAC system and return to the occupied space as a threat. REQUIRED TESTING---The illustration above presents a means of creating a relatively non-turbulent supply air environment to determine if live virus can survive the turbulence of the HVAC fans and return to the occupied areas. TEST METHOD -1- Build a tent as illustrated and run system until the air in the tent matches supply air quality. -2- Alter the HVAC automatic dampers to have D1 and D3 closed and D2 open (full recirculation) if fan CFM’s allow. -3- Test the tent air and the room air for the live virus. -4- Introduce the live virus into the room outside of the tent. -5- Run for enough time to have tent refilled completely with return air that had the live virus introduced. -6- Test again for the live virus in the tent and the room. Record the quantity of live virus at both locations. -7- Alter the HVAC automatic dampers to have D1 and D3 open and D2 closed.(full outdoor air) if allowable. Repeat testing. CONSIDERATION---If the tent live virus is absent in both the full outdoor air and full recirculation scenarios there is no benefit in altered ventilation: however, the full outdoor air position will have significant damage implications regarding Climate Change. If there is benefit in extra ventilation, it should be weighed against the negative impact, regarding Climate Change. 11.192
