Method and arrangement for monitoring the operation of a rotating heat exchanger with two adjacent ducts 1, 2 intended for air to flow through in opposite directions. Monitoring of the operation is effected by monitoring the temperature of the incoming air T, an indication of operational disruption being given if this temperature falls below a predetermined temperature, for example +10C, which is lower than that which can normally be expected after normal heat recovery in the exchanger rotor 3. <IMAGE> |
