Provide oxygen-rich air

According to Remko, fresh air is a prerequisite for good health. 'Maybe you recognize it from when you were at school. At the end of the day, you felt sluggish. We now know that this was mainly due to the increased CO2 content in the closed classroom. People breathe in oxygen and CO2 out. If carbon dioxide is not removed and insufficient oxygen-rich air is supplied, you lose concentration and you can get a headache.'

Air exchange regulations

But what exactly is ventilation? Remko: 'Simply put, ventilation is the renewal of the air.' It is not for nothing that the building decree states that 35m3 per hour per person must flow fresh air into a room. Remko: 'Especially for virus infections, 60m3 per hour per person is recommended. In our space-in-space solutions, that standard is the minimum standard, in the Ahrend Qabin and Cerene boxes that value is even more than twice as high.'

Cooler, fresh air

Cooler, fresh air entering the box through a labyrinth of passages at the bottom of the walls pushes the warm air up. This circulation is what constantly refreshes the air.
According to the laws of physics, the warm air molecules vibrate at a higher rate. This means that they take up more space and displace the air. In other words, warm air is less dense and therefore ‘lighter’ than cold air. This is how the cold air pushes the warm air up.
