PURPOSE:To form a heat exchanger displaying a high heat transfer coefficient which is a feature of a fluidized bed heat exchanger by stopping the operation of a blower after detecting that water contents adhering to solid particles have been eliminated. CONSTITUTION:Detectors 8 and 9 positioned at the inlet and outlet of a fluidized-bed heat exchanger 7 are detectors detecting the relative humidity, and are connected to a controller 10 controlling a motor 4 for a blower 3. In this case, the controller 10 effects a control such that it open a contact 16 when relative humidity values shown by detectors 8 and 9 are equal to each other, and hence the blower 3 continues to operate until solid particles 5 are dried. Accordingly, even when the operation of a cycle equipment 11 is resumed, an excellent fluidity is obtained, and hence a function desired by the fluidized-bed exchanger is sufficiently achieved. |
