Abstract
There is provided a dehumidifying device for dew point temperature adjustment that adjusts a dew point temperature of air to a temperature of about −20° C. or lower, the device including an adjusting unit that adjusts a dew point temperature by adjusting at least one driving operation that is selected from a rotational frequency of a supply fan for supplying air into the dehumidifying device for dew point temperature adjustment, a rotating speed of a dehumidifying rotor, an opening degree of a blow-out air volume adjustment damper, a rotational frequency of an exhaust fan for exhausting air, and an opening degree of an exhaust air volume adjustment damper.
Claims9
A dehumidifying device for dew point temperature adjustment that adjusts a dew point temperature of air to a temperature of about −20° C. or lower, the device comprising:
- an adjuster portion that adjusts the dew point temperature by adjusting at least one driving operation that is selected from a rotational frequency of a supply fan inside the dehumidifying device for dew point temperature adjustment for introducing air into the dehumidifying device for dew point temperature adjustment by an adjuster of the supply fan, a rotating speed of a dehumidifying rotor by an adjuster of a dehumidifying rotor, an opening degree of a blow-out air volume adjustment damper by an adjuster of a blow-out air volume adjustment damper, a rotational frequency of an exhaust fan for exhausting air by an adjuster of an exhaust fan, an opening degree of an exhaust air volume adjustment damper by an adjuster of an exhaust air volume adjustment damper, and a temperature of a regeneration heater, wherein
- the adjuster portion adjusts the dew point temperature according to a contribution ratio to a dehumidifying function,
- the adjuster portion performs
- a first control that adjusts the dew point temperature by adjusting at least one of the rotational frequency of the exhaust fan, the rotating speed of the dehumidifying rotor, and the opening degree of the exhaust air volume adjustment damper, and
- a second control that adjusts the dew point temperature by adjusting at least one of the opening degree of the blow-out air volume adjustment damper and the rotational frequency of the supply fan,
- a contribution ratio of the first control is larger than a contribution ratio of the second control, and
- the adjuster portion performs the second control for fine adjustment of the dehumidifying function.
A method of using a dehumidifying device for dew point temperature adjustment that adjusts a dew point temperature of air to a temperature of about −20° C. or lower, the method comprising:
- adjusting at least one driving operation that is selected from a rotational frequency of a supply fan inside the dehumidifying device for dew point temperature adjustment for introducing air into the dehumidifying device for dew point temperature adjustment, a rotating speed of a dehumidifying rotor, an opening degree of a blow-out air volume adjustment damper, a rotational frequency of an exhaust fan for exhausting air, an opening degree of an exhaust air volume adjustment damper, and a temperature of a regeneration heater;
- adjusting the dew point temperature according to a contribution ratio to a dehumidifying function;
- and
- Performing
- a first control that adjusts the dew point temperature by adjusting at least one of the rotational frequency of the exhaust fan, the rotating speed of the dehumidifying rotor, and the opening degree of the exhaust air volume adjustment damper, and
- a second control that adjusts the dew point temperature by adjusting at least one of the opening degree of the blow-out air volume adjustment damper and the rotational frequency of the supply fan,
- wherein a contribution ratio of the first control is larger than a contribution ratio of the second control, and
- the second control is performed for fine adjustment of the dehumidifying function.
