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.
