Abstract: A dew point temperature sensor detects and sends the dew point temperature of the supply air to a dry area, as a supply air dew point temperature, to a controller. The controller has a speed of rotation of the regenerating side fan (the regenerating air flow rate) to control, and determines a control value (the regenerating air flow rate) that causes the supply air dew point temperature to go to a target dew point temperature, and determines a supply air processing pre-cooling coil exit temperature setting value in accordance with this control value (where if the control value is in the direction of reducing the regenerating air flow rate, the supply air processing pre-cooling coil exit temperature setting value is increased). Note that what is controlled is the speed of rotation of the desiccant rotors, or the exit temperatures of the air heated by the hot water coils.

Abstract: 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 ?t in the air on the treating side before and after passing through a desiccant rotor. The evaluating portion receives the temperature difference ?t from the temperature difference detecting portion and compares the temperature difference ?t to a setting value ?tth 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.

Abstract: In a state estimating apparatus, an input space quantization section quantizes an input space according to a required precision of output data. A storage section calculates and stores the number of times of occurrence of output data corresponding to each input event in the quantized input space, the mean values of the output data, and the change amounts of the output data. A neighborhood definition section calculates an input space neighborhood satisfying the required precision of the output. A similar case extraction section zooms up the predetermined neighborhood of the input space to the predetermined degree and extracts input case similar to the neighborhood from input case in the input space. A similarity determination section determines the similarity between the new input event and the extracted similar input cases on the basis of the degree of zooming.
