Measuring CO2 is often not enough

Indoor air quality is nowadays assessed, if at all, by temperature, humidity and carbon dioxide (CO2) concentration. However, people often complain about air quality even though all these indicators are at optimum levels. So what substances further degrade air quality?

Driven by real need

What is the difference between uncontrolled ventilation and VAV (variable air volume) and DCV (demand controlled ventilation)? The article describes the advantages, disadvantages and operation of these systems. The VAV system is explained using a specific example in our company. The initial set-up of the system and its several years of operation are described. The ventilation is regulated by air quality sensors, which are manufactured in-house.

Carbon dioxide indoors – real measurements

Our company has conducted surveys in the nursery, school and office. We placed air quality sensors in the classrooms and office. Where were the carbon dioxide readings the worst? You may not be surprised by the results, but is it okay for children to spend so much time in enclosed rooms where the air quality is often alarming? The survey we conducted in bedrooms shows that even at night the air quality is not better, but rather worse. This means that we are breathing poor quality air for more than half of the day. Do you think that's okay?

On what principles do air quality sensors work?

Getting lost in technical terms related to measuring the concentration of various substances in the air? Sensors for measuring CO2, CO, VOCs etc. work on three basic principles, the most commonly used of which is the NDIR principle. What does NDIR mean and how do sensors work on this and other principles?

Smart ventilation that saves you money

The heater is always on and the window above it is open because the room is unbreathable! Or a closed window, so that the heating is not unnecessary, but the air is such that it is impossible to be in the room for long periods of time. Do you know these situations? And do you know what smart ventilation is?

Carbon monoxide poisoning

CO leaks have been a much discussed topic recently. Many people have died from carbon monoxide poisoning, despite the fact that it would have taken so little - the purchase of a home CO sensor that could alert homeowners to this dangerous gas. In the section "Products - we inform" you will find articles related to this topic.
