PIDs in the HVAC Industry

By 15th May 2020PID Sensor

Inadequate ventilation, which may occur if heating, ventilating, and air conditioning (HVAC) systems do not effectively distribute air to people in a building, may cause indoor air quality (IAQ) issues, as well as be an important factor in sick building syndrome.

PIDs in the HVAC Industry - ION ScienceHowever, inadequate indoor ventilation today is being combatted by intelligent HVAC systems. HVAC systems are now being developed and integrated in a standard way to establish a balance between adequate ventilation to prevent sickness, like those associated with sick building syndrome, as well as energy efficiency. 

Building management systems are one solution to address the balance, whereby widely distributed sensors that, for example, monitor temperature, humidity, and volatile organic compounds (VOCs) can be used to optimize HVAC performance but minimize energy use.

As sensor technology and networking platforms improve and the development of ‘smarter’ buildings and cities is ongoing, publicly displaying green credentials is becoming essential for organizations in the new environmentally-aware society.

PIDs in the HVAC Industry - ION ScienceDue to their ability to provide reliable low-level detection over a range of environmental conditions, photoionization detectors (PIDs) have been successfully employed in the built environment to monitor dangerous VOCs. Data obtained from these PID sensors can be used to modify traffic flows and inform the industry to modify processes, as well as help control indoor air quality to reduce VOC exposure.

ION Science manufactures and supplies more PID sensors than any other company in the world with our patented PID sensor technology trusted globally. Our sensors are proven to resist humidity and contamination, providing outstanding results when detecting VOCs in challenging HVAC environments.
