4.2 Thermal recovery rotor
4.2.1 Function
Figure 4.2 Thermal recovery rotor
The thermal rotor is, depending on the ambient conditions, used either for cooling or for heating of the
supply air. This is done by exchanging heat between the supply air stream passing through the lower half of
the rotor, and the exhaust air stream passing through the top half in the opposite direction while the rotor
rotates.
The thermal rotor is manufactured from aluminium with many small channels through which the air passes,
making a large contact surface to transfer the heat.
The rotor is driven by an electric motor and a drive belt around the circumference of the rotor.
4.2.2 Rotor
The rotor surface must be inspected regularly.
If the rotor is dirty it can be cleaned with a vacuum cleaner, or with low pressure compressed air if necessary.
4.2.3 Rotor seals , drive belt and drive motor
The drive belt must be checked after the first 100 hours of operation.
The rotor drive motor, drive belt and seals should be replaced if necessary, or at the maximum intervals
according to the maintenance schedule.
Belt tension can be adjusted by shortening the belt.
The clearance between the rotor surface and the seals must be checked during inspection. Adjust the seals if
necessary.
