Can CO2 sensors be used to assess COVID-19 transmission ...

2021-01-15· Finally, CO 2 sensors can be used to increase energy efficiency, by allowing users to regulate ventilation around a CO 2 setpoint (, 1000 ppm), such that enough fresh air is taken into the building to maintain occupant comfort, but not so much as to waste excessive energy on heating and cooling (, demand control ventilation).

Beyond the classroom: An expanded view of flow control ...

2020-11-10· In one case study, a water treatment facility was designing a pH control system where CO2 would be sparged into a body of water to control the pH of the water. (See Figure 5.) The application involved the need to control mass flow over a wide flow range to cater to various volumes of water, while at the same time, reducing time lag between CO2 injection and pH changes of the water.

Indoor CO2 sensors for COVID-19 risk mitigation: Current ...

2021-05-18· Can we reduce ventilation if CO 2 levels can be maintained below 1000 ppm? In some facilities, CO 2 monitoring is used to estimate occupancy, which in turn is used to reduce outdoor air intake if/when occupancy is low. This is known as demand control ventilation and in non-pandemic conditions can be a useful energy-saving feature. However ...

concentration (Co) of carbon dioxide seldom varies by more than 100 ppm from the nominal value.* Because of this and in lieu of installing an outdoor CO2 sensor, most designers use either a one-time reading of the outdoor CO2 concentration at the building site or a conservative value from historical readings. This simplifies control,

7 Reasons Why You Should Measure CO2 Inside Buildings ...

2016-04-08· Using CO2 sensors for ventilation control can assist in these cases. However, other systems with audible and visual alarms, such as the ESRAD-102 can be installed (Figure 2) warning workers and occupants of dangerous levels of CO2. The sensor is installed in the space with the CO2 source and an alarm indicator is placed outside.
