CO₂

All other information on Carbon Dioxide can be found under CO₂ in the main product menu.

• the air in a crowded, poorly ventilated room may exceed the recommended upper limit of 1000 ppm CO₂ in a few minutes?
   

• prolonged exposure will result in efficiency loss, discomfort, and eventually health hazard?
   

• the power consumption to maintain adequate ventilation may be 100W per person - large savings can be made by adapting ventilation to actual demand?

• keeping track of CO₂ concentration, temperature and relative humidity (RH) variations

• adapting the personal load and airing to actual air quality

• controlling ventilation automatically, either locally or centrally by using the outputs provided by AP:s CO₂-sensors

Air quality?
We perceive air to be fresh when it is unpolluted, and has adequate temperature and humidity.

We recognize it - especially when it is missing.

People adapt easily, but coming into a room from the outside it is easy to  decide if a room needs airing.

A consequence of the above is that people tend to stay too long in low quality air.

It is generally believed that the ability to concentrate and perform, as well as comfort and spirit, will, consciously or not, drastically decrease with decreasing air quality.

The most sensitive measure of air quality in this sense is the concentration of carbon dioxide (CO₂).

Fresh air contains approximately 370 ppm (volume parts per million) CO₂, but increases rapidly with an increasing number of people in a room.

Expired air contains as much as 4000 ppm CO₂.

In a poorly ventilated classroom, the recommended hygienic limit of 1000 ppm may be exceeded already after 15 minutes.

To maintain this level, each breath must be compensated with more than 30 liters
(6 gallons) of fresh air.

With the air quality sensor from AP on the wall, it is possible to control that the CO₂ concentration, temperature, and relative humidity are within tolerable limits, and adapt activities accordingly.

Or the reverse: The AP CO₂-sensor may also be connected to the ventilation system for automatic control of the air flow.

The CO₂-sensor is simple to use, does not require any calibrations or settings.

Our infrared gas sensing technology addresses a wide variety of applications including:

• HVAC (Commercial & Residential)

• Industrial

• Harsh Environment

• Agricultural

• Medical

• Swimming Halls
