add info - How does a Heat Recovery Ventilator Work

Decentralised Heat Energy recovery takes place thanks to the reversible operation of the fan, which consists of 2 cycles.

Heat Recovery Cycle I

The warm, consumed exhaust air passes out of the room and flows through the ceramic heat exchanger.The exhaust air heats and humidifies the heat exchanger. In 70 seconds, the heat exchanger heats up before the fan switches to the supply air mode.

Heat Recovery Cycle II

The fresh outdoor air flows through the ceramic heat exchanger, which removes stored heat until the room reaches the temperature.

In 70 seconds, the heat exchanger cools down, and the fan switches to exhaust mode. The cycle starts again. Switching to the supply and exhaust mode takes place every 70 seconds.

A decentralised MVHR unit (Mechanical Ventilation with Heat Recovery) is designed for continuous operation 365 days a year.
