ADSORBING/DESORBING DEVICE AND ADSORBATE EXCHANGE STATUS MONITORING METHOD
A moisture exchange status monitoring device is provided. The moisture exchange status monitoring device is provided with: a temperature difference detecting portion; an evaluating portion; a setting value storing portion; and an evaluation result outputting portion. The temperature difference detecting portion detects a temperature difference Δt in the air on the treating side before and after passing through a desiccant rotor. The evaluating portion receives the temperature difference Δt from the temperature difference detecting portion and compares the temperature difference Δt to a setting value Δtth that is stored in the setting value storing portion, to evaluate the status of moisture adsorption of the moisture from the air on the treating side of the desiccant rotor. The evaluation result outputting portion outputs the evaluation result for the status of moisture adsorption, from the evaluating portion, as the monitoring result for the status of exchange of the moisture of the desiccant rotor. Similarly, on the regenerating side, the temperature difference Δt in the air on the regenerating side before and after passing through the desiccant rotor is detected to enable monitoring of the status of desorption of the moisture.
