Advice on avoiding Covid-19-spreading via recirculated air ...

· However, it isn’t known if the usual winter set point for CO2 is appropriate in a Covid-19 pandemic. Where an existing HVAC system is recirculating air containing small clusters of SARS-CoV-2 virus, the risks of air-recirculation need to be quantified. In the meantime, REHVA advises avoiding central air-recirculation during Covid-19 episodes and closing the recirculation dampers, even if ...

Even with other controls in place (including; social distancing, frequent hand washing, increased cleaning regimes, use of face coverings/transparent barriers/shields etc.), employers should still consider the risk from airborne transmission of the Covid-19 virus from aerosols in poorly ventilated indoor spaces, particularly if individuals are in the same room together for an extended period ...

How CO2 Gas Sensors Could Help Control COVID-19

· This hierarchy places elimination (physically removing the pathogen) at the top of a priority list, followed by engineering controls (separating people from the pathogen), administrative controls (telling people what to do), and personal protective equipment. Ventilation controls – such as CO 2 gas sensors – are a type of engineering control. They separate people from the pathogen by ensuring …

When used correctly, they cover the nose and mouth, which are the main sources of transmitting coronavirus (Covid-19), confining/containing droplets and larger particles and helping prevent them from entering the general environment. There are some circumstances when wearing a face covering is required as a precautionary measure. You can find out when workers need to wear a face covering on …

ASHRAE® Recommendations for COVID-19

to disable demand-controlled ventilation (DCV).2 DCV is a common energy-saving control strategy that reduces outdoor airflow during periods of partial occupancy, typically using a carbon dioxide (CO2) sensor, an occupancy sensor, or some other means of counting people. Disabling DCV will …

Demand-Controlled Ventilation (DCV) - SVACH

Designers assume that controlling CO2 controls all occupancy-related pollutants. CO2 sensors are relatively precise, reliable, and inexpensive compared to other types of DCV pollutant sensors. Occupancy sensors count occupants and regulate ventilation airflow accordingly. A major purpose of ventilation systems is to control relative humidity. Relative humidity (Rh) compares air’s water vapor …
