Stiebel Eltron promotes IAQ improvements for classrooms

Stiebel Eltron is promoting the use of its VRL-C heat-recovery ventilation systems as a measure to improve air exchange in heavily frequented rooms, including classrooms.

“A ventilation device not only brings fresh, virus-free air into the room and recovers valuable energy from the exhaust air,” says the company. “It also lowers the CO₂ concentration and the moisture content and removes other air pollutants from the room.”

The VRL-C ventilation unit is a flexible solution that discharges used and polluted air, while filtering and feeding fresh air into the room from outside.

“The devices are easy to maintain and designed for quick and easy service,” says the company. “An additional sensor accessory measures the CO₂ concentration of the room air and regulates the air output of the device fully automatically until the CO₂ value falls below the set value again.

“The device can be switched to basic ventilation or a higher air level via a motion sensor accessory. Thanks to the aluminium cross-countercurrent heat exchanger, the device recovers valuable thermal energy from the exhaust air and transfers it to the supply air – this avoids heating energy losses.”

Stiebel Eltron says the VRL-C can be used retrospectively in classrooms, kindergartens, meeting rooms, offices and community halls, either as a ceiling extension or integrated into the ceiling. The swivelling housing cover has been designed for uncomplicated maintenance of the device.

In Germany, the federal government has provided funds to help improve IAQ in schools and daycare centres. New installations of ventilation systems are funded with up to 80 per cent of the total costs for planning, purchase and installation. The scheme is open to institutions for children under the age of 12 and their public and private providers – daycare centres, after-school care, daycare and state-recognised public education schools.
