In order to tackle the increase, the deteriorated development of adsorption capacity of dehumidifying piece of damping load of this extraneous gas, improve gradually the cooling capacity of precooling helix tube, be the temperature adapting with the adsorption capacity of dehumidifying piece by the control of precooling helix tube outlet temperature.
Therefore, passed through the precooling helix tube outlet temperature of extraneous gas of precooling helix tube along with the deteriorated of adsorption capacity of dehumidifying piece declines, precooling helix tube outlet temperature forms the index that represents the dehumidifying degradation of piece or the surplus energy of adsorption capacity.
And in the time that precooling helix tube outlet temperature reaches predefined setting outlet temperature, the adsorption capacity of judgement dehumidifying piece approaches limit, thereby control the de-switching part of suction, dehumidifying piece is switched to reproduced state from adsorbed state.
Therefore, can be using precooling helix tube outlet temperature as index, detect exactly adsorption capacity deteriorated or not enough of dehumidifying piece, can switch in the appropriate moment adsorbed state and the reproduced state of dehumidifying piece, thereby realize the high efficiency use of dehumidifying piece.

Same, the 2nd drive division 102 slides the door body 901 of the 2nd sliding door apparatus 802 and the door body 901 of the 4th sliding door apparatus 804 by the driving of motor 915 in the opposite direction.; if the door body 901 of the 2nd sliding door apparatus 802 is positioned at the position of closing the 1st air feed connector 92, opening the 1st reflux gas connector 93; a door body 901 for the 4th sliding door apparatus 804 is positioned at and opens the 2nd air feed connector 96, closes the position of the 2nd reflux gas connector 97; if a door body 901 for the 2nd sliding door apparatus 802 is positioned at opens the 1st air feed connector 92, close the position of the 1st reflux gas connector 93, a door body 901 for the 4th sliding door apparatus 804 is positioned at the position of closing the 2nd air feed connector 96, opening the 2nd reflux gas connector 97.
Next, the precooling helix tube outlet temperature of measuring at outlet temperature meter 613 reaches while setting outlet temperature, inhales the de-switching part 80 of de-switch control portion control suction and switches between the 1st use state and the 2nd use state.
Under the 1st use state, open the 1st extraneous gas connector the 91, the 1st air feed connector the 92, the 2nd reflux gas connector the 97, the 2nd exhaust connector 98, close the 2nd extraneous gas connector the 95, the 2nd air feed connector the 96, the 1st reflux gas connector the 93, the 1st exhaust connector 94, the 1st is connected with extraneous gas path 6 and is adsorbed state except the 1st dehumidifying piece 83 of moist chamber 82, and the 2nd is connected with reflux gas path 7 and is reproduced state except the 2nd of moist chamber 84 piece 85 that dehumidifies.
Under the 2nd use state, close the 1st extraneous gas connector the 91, the 1st air feed connector the 92, the 2nd reflux gas connector the 97, the 2nd exhaust connector 98, open the 2nd extraneous gas connector the 95, the 2nd air feed connector the 96, the 1st reflux gas connector the 93, the 1st exhaust connector 94, the 1st is connected with reflux gas path 7 and is reproduced state except the 1st dehumidifying piece 83 of moist chamber 82, and the 2nd is connected with extraneous gas path 6 and is adsorbed state except the 2nd of moist chamber 84 piece 85 that dehumidifies.
As mentioned above, by being the slide construction of door body 901 of a slice plate body, between the 1st, the 2nd, the 3rd, the 4th sliding door apparatus 801,802,803,804 and the door body 903 as fixed part, need the position minimizing of sealing.As a result, the air-tightness between door body 901 and door body 903 uprises.In addition, can carry out at short notice the switching of stream by this structure, thereby the air of inhibition regeneration use mixes with the air of adsorption treatment object.That is, as in the past, at blade in the situation that rotating shaft rotates, make in order to resist blade load multiple blades rotate simultaneously need to be larger moment of torsion, thereby reduce the switching speed of blade in order to ensure the rotary speed that this moment of torsion need to reduce motor.But, in the present embodiment, make a body 901 rectilinear motions due to guide rail 907 support door body load time, tail off so close the needed power of a body 901.Therefore, thus the diameter that can realize increasing motor pulley 914 with speed switch door body faster.Therefore humidity control when, stream switches is more stable.
In addition, because the top slot part 905 of door body 903 leads to the deflector roll 904 of the top edge of being located at a body 901, the door guide roller 906a that is located at the lower limb of a body 901 advances on the guide rail 907 of inside of bottom slot part 906 that is configured in door body 903, so this structure can be because blast produces lateral shift.

Below, the effect of said structure is described.
(absorption extraneous gas)
Air-feeding ventilator 624 passes through extraneous gas path 6 to indoor air feed by the extraneous gas OA that flows into housing 1 from extraneous gas mouth 2.In upstream side extraneous gas path 61, extraneous gas OA is through precooling helix tube 612, and precooling helix tube 612 carries out cooling to extraneous gas OA, thereby its damping load (absolute humidity) is adjusted.Adjustment operation about damping load sees below.In the air line chart shown in Fig. 8, this is the track from an A1 to an A2.
Extraneous gas OA through precooling helix tube 612 flows in the 1st and uses the suction of state to take off switching part 80 at this.Under the 1st use state, the 1st extraneous gas connector the 91, the 1st air feed connector the 92, the 2nd reflux gas connector the 97, the 2nd exhaust connector 98 is opened, the 2nd extraneous gas connector the 95, the 2nd air feed connector the 96, the 1st reflux gas connector the 93, the 1st exhaust connector 94 is closed, the 1st is connected with extraneous gas path 6 and is adsorbed state except the 1st dehumidifying piece 83 of moist chamber 82, and the 2nd is connected with reflux gas path 7 and is reproduced state except the 2nd of moist chamber 84 piece 85 that dehumidifies.
Extraneous gas OA is through the 1st the 1st dehumidifying piece 83 except moist chamber 82, and the moisture that adsorbs extraneous gas OA by the 1st dehumidifying piece 83 dehumidifies.In the air line chart shown in Fig. 8, this is the track from an A2 to an A3.
Flow into downstream extraneous gas path 62 through the 1st extraneous gas OA except moist chamber 82, cooling spiral pipe 621 carries out cooling (summer time, intergrade) and is adjusted to set point of temperature extraneous gas OA.Or by heating helix tube 622, extraneous gas OA is heated to (teletostage), thereby extraneous gas OA is adjusted to set point of temperature.In addition, by gasifying type humidifier 623, extraneous gas OA is carried out to humidification (teletostage) as required.
Extraneous gas after damping, temperature adjustment is supplied to gas circuit 31 by air-feeding ventilator 624 from air supply opening 3 as supply gas SA.In the dew-point temperature of measuring supply gas SA (extraneous gas OA) for dew point instrument 311 in gas circuit 31, feed air temperature meter 312 is measured the temperature of supply gas SA (extraneous gas OA).
The motor-driven valve 626 of the motor-driven valve 625 of the temperature that feed air temperature control part is measured according to feed air temperature meter 312 to cooling spiral pipe 621 or heating helix tube 622 is adjusted, the heating efficiency of the cooling capacity to cooling spiral pipe 621 or heating helix tube 622 is controlled, thereby is setting value by the temperature control of supply gas SA (extraneous gas OA).
In addition, the dew-point temperature of the supply gas SA (extraneous gas OA) that air feed humidity control part is measured according to dew point instrument 311 is adjusted operating portion 627, gasifying type humidifier 623 is controlled, thereby be setting value by the humidity control of supply gas SA (extraneous gas OA).
The dew-point temperature of measuring at dew point instrument 311 is lower than setting dew-point temperature, damping load control part judges that with respect to the adsorption capacity of minimizing the 1st dehumidifying piece 83 of the damping load of extraneous gas OA be superfluous, thereby by adjusting the motor-driven valve 614 of precooling helix tube 612, the cooling capacity of precooling helix tube 612 is reduced.Thus, suppress to flow into the dehumidifying of the 1st dehumidifying piece 83 extraneous gas OA before, make its minimizing corresponding to the damping load of extraneous gas OA.
In addition, than setting dew-point temperature high in the situation that, judge that with respect to the dehumidify adsorption capacity of piece 83 of the damping load regulation 1 of extraneous gas OA be not enough in dew-point temperature.This phenomenon, the damping load that has an extraneous gas OA increase and make the hypodynamic situation of energy of adsorption of the 1st dehumidifying piece 83 and due to adsorption capacity deteriorated of the 1st dehumidifying piece 83 with respect to the underloaded situation of damping of extraneous gas OA, both do not have difference on the damping load regulation 1 with respect to extraneous gas OA dehumidifies the not enough this point of adsorption capacity of piece 83.
Therefore, in order to improve the cooling capacity of precooling helix tube 612, damping load control part is adjusted the motor-driven valve 614 of precooling helix tube 612 according to dew-point temperature, and the cooling capacity of precooling helix tube 612 is improved.Thus, strengthening is carried out the cooling dehumidifying of carrying out by precooling helix tube 612 to the extraneous gas OA flowing into before the 1st dehumidifying piece 83, thereby reduces the adjustment of the damping load (absolute humidity) of extraneous gas OA.
(reflux gas regeneration)
Scavenger fan 722 is discharged by reflux gas path 7 the reflux gas RA that flows into housing 1 from reflux gas mouth 4 to room.In upstream side reflux gas path 71, reflux gas RA is through heating helix tube 711, and regeneration inlet temperature meter 713 is measured the temperature of reflux gas RA.The temperature of the reflux gas RA that regeneration temperature control part is measured according to regeneration inlet temperature meter 713 is adjusted motor-driven valve 712, thereby controls the heating efficiency of heating helix tube 711, thereby controls the regeneration temperature of reflux gas RA.In the air line chart shown in Fig. 8, this is the track from an A5 to an A6.
Passed through the reflux gas RA of heating helix tube 711 through the 2nd the 2nd dehumidifying piece 85 except moist chamber 84, reflux gas RA sloughs the moisture of the 2nd dehumidifying piece 85, and the 2nd dehumidifying piece 85 is regenerated.In the air line chart shown in Fig. 8, this is the track from an A6 to an A7.
Passed through the 2nd reflux gas RA except moist chamber 84 and flowed into downstream reflux gas path 72, reflux gas RA is deflated fan 722 as Exhaust Gas EA and discharges to outside from exhaust outlet 5.
(inhaling de-switching)
As mentioned above, along with the deteriorated development of adsorption capacity of the 1st dehumidifying piece 83, improving gradually the cooling capacity of precooling helix tube 612, is the temperature adapting with the adsorption capacity of dehumidifying piece by the control of precooling helix tube outlet temperature.Therefore, the precooling helix tube outlet temperature of having passed through the extraneous gas OA of precooling helix tube 612 declines along with adsorption capacity deteriorated of the 1st dehumidifying piece 83, so precooling helix tube outlet temperature becomes the index that represents the 1st dehumidifying degradation of piece 83 or the surplus energy of adsorption capacity.
Therefore, the precooling helix tube outlet temperature that outlet temperature meter 613 is measured reaches while setting outlet temperature, inhale de-switch control portion and judge that the adsorption capacity of the 1st dehumidifying piece 83 approaches limit, controlling the de-switching part 80 of suction makes the 1st use state switch to the 2nd use state, making the 1st dehumidifying piece 83 is reproduced state, and the 2nd dehumidifying piece 85 is adsorbed state.
, if the precooling helix tube outlet temperature that outlet temperature meter 613 is measured reaches setting outlet temperature, close the 1st extraneous gas connector 91, the 1st air feed connector 92, the 2nd reflux gas connector 97, the 2nd exhaust connector 98 and form closed condition, open the 2nd extraneous gas connector 95, the 2nd air feed connector 96, the 1st reflux gas connector 93, the 1st exhaust connector 94 and form open state, the 1st is connected with reflux gas path 7 and is reproduced state except the 1st dehumidifying piece 83 of moist chamber 82, and the 2nd is connected with extraneous gas path 6 and is adsorbed state except the 2nd dehumidifying piece 85 of moist chamber 84.
Now, the regeneration processing of the 2nd dehumidifying piece 85 in reproduced state finishes.Describe below.Make the 2nd dehumidifying piece 85 (the 1st dehumidifying piece 83) slough its moisture and regenerate.This regeneration is processed needed regeneration required time and is determined according to the regeneration temperature of reflux gas RA.Therefore the durable time that, the regeneration temperature of reflux gas RA is set as make the regeneration required time of the 2nd dehumidifying piece 85 (the 1st dehumidifying piece 83) to finish with respect to the adsorption capacity of the 1st dehumidifying piece 83 (the 2nd dehumidifying piece 85) is short.Thus, the precooling helix tube outlet temperature that can measure at outlet temperature meter 613 reaches to be set before outlet temperature, completes the regeneration processing of the 2nd dehumidifying piece 85.
Or, also the precooling helix tube outlet temperature that can measure at outlet temperature meter 613 reaches setting outlet temperature, and when the temperature that the temperature that the regeneration inlet temperature meter 713 of being located at upstream side reflux gas path 71 is measured is measured with the regeneration outlet temperature meter 721 of being located at downstream reflux gas path 72 equates, judge the regeneration ending of the 2nd dehumidifying piece 85 (the 1st dehumidifying piece 83), then control the de-switching part 80 of suction and be switched to the 2nd use state from the 1st use state.
In this case, even because the precooling helix tube outlet temperatures such as damping load variations reach while setting that time of outlet temperature shortens or the recovery time is elongated, also can make reliably the dehumidifying piece regeneration in reproduced state, and can under the state that has improved adsorption capacity, switch.
So, can be using precooling helix tube outlet temperature as index, detect exactly adsorption capacity deteriorated, not enough of the 1st dehumidifying piece 83, the 2nd dehumidifying piece 85, can switch in the appropriate moment adsorbed state and the reproduced state of the 1st dehumidifying piece 83, the 2nd dehumidifying piece 85, thereby realize the high efficiency use of the 1st dehumidifying piece 83, the 2nd dehumidifying piece 85.
In addition, in the present embodiment, switching to the 2nd use state using precooling helix tube outlet temperature as index from the 1st use state, adsorbed state and reproduced state are switched, is also the same but certainly switch to the 1st use state from the 2nd use state.In addition, as the index of the switching of adsorbed state and reproduced state, also can add the aperture of the motor-driven valve 614 of precooling helix tube 612.For example, do not reach setting outlet temperature in precooling helix tube outlet temperature, but the aperture of motor-driven valve 614 reaches in the situation of standard-sized sheet (100%), judgement can not be tackled increase, adsorption capacity deteriorated of more damping load, control and inhale de-switching part 80 from the 1st use state to the 2nd use state, or switch to the 1st use state from the 2nd use state.
In the above-described embodiment, suck in reflux gas path 7 the reflux gas RA from indoor as regeneration air, but regeneration air is not limited to reflux gas RA, can be also outdoor air, extraneous gas OA.In addition, dew point instrument 311 is located at in gas circuit 31, but also can be located on downstream extraneous gas path 62.
