The below effect of explanation present embodiment.
At first, at channel design as shown in Figure 1, when humidification moves, start rotor 12 rotations that make air dehumidifying and humidifying apparatus 1 and drive each ventilating fan 14,18.Import extraneous gas by aspirating air pipe 5A, first passage converter 20 and aspirating air pipe 4A in the first passage 10, this extraneous gas flow into binding domain 12A as absorbed air.Extraneous gas its moisture in the binding domain 12A of rotor 12 is adsorbed to hygroscopic material and is dehumidified, and is discharged to outdoor with ventilating fan 14 through discharge duct 7A, second channel converter 21 and discharge duct 8 from absorption.In addition, import extraneous gas by aspirating air pipe 5B, electrical heat exchanger 3, first passage converter 20 and aspirating air pipe 4B in the second channel 11.This extraneous gas carried out the electric heating exchange with indoor hot and humid ventilation air in electrical heat exchanger 3 before flowing into Humidifying dehumidifying portion 2, be higher than in its temperature and humidity under the state of the temperature of extraneous gas and humidity to flow into second channel 11 as regeneration air.And, in second channel 11 by being directed into after heater 17 heating among the regeneration zone 12B of rotor 12.Rotor 12 uses as regeneration zone 12B by rotating to move in the second channel 11 in the part of first passage 10 adsorption moistures.That is, the extraneous gas by high temperature makes the moisture that is adsorbed in hygroscopic material by desorb, thereby forms the wet air that comprises this moisture.This air through regeneration with ventilating fan 18, discharge duct 7B, second channel converter 21 and steam line 9 and in the humidifying chamber to indoor discharge.
When operation dehumidifying, first passage converter 20 is connected the aspirating air pipe 5B that is provided with electrical heat exchanger 3 in the passage with aspirating air pipe 4A, and the extraneous gas that will finish heat exchange is fed to first passage 10.Indoor when moving owing to generally dehumidify is high temperature for low temperature is outdoor, therefore carry out that electric heating exchanges and the air that becomes relative low temperature and low humidity through the extraneous gas of electrical heat exchanger 3 and the ventilation air of low temperature and low humidity, this air is supplied to the binding domain 12A of rotor 12 as absorbed air.Its result, the air of dehumidifying is discharged to indoor and dehumidifies indoor in first passage 10.In addition, the extraneous gas that does not carry out electric heating exchange in the second channel 11 is supplied through aspirating air pipe 5A, first passage converter 20 and aspirating air pipe 4B and by humidification, this humidifying air through discharge duct 7B, second channel converter 21 and discharge duct 8 to outdoor discharge.
In the present embodiment owing to electrical heat exchanger 3 is set in the upstream of Humidifying dehumidifying portion 2, when moving, humidification makes extraneous gas and from carrying out electric heating exchange between the ventilation air of indoor discharge, thereby under the state of temperature that improves extraneous gas and humidity, make extraneous gas flow into the regeneration zone 12B of rotor 12, thereby improved the temperature of the extraneous gas that imports to rotor 12 regeneration zone 12B.Thus, the relative humidity between the absorbed air of regeneration air in the second channel 11 and first passage 10 is increased, can promote the desorb of moisture among the regeneration zone 12B and increase the humidification amount.Therefore, with the temperature of extraneous gas or humidity is irrelevant can carry out humidification when keeping indoor temperature.At this, though adopt electrical heat exchanger 3 that the humidity of the extraneous gas that is fed to second channel 11 is increased, but compare the temperature that can improve extraneous gas with the situation that only exchanges sensible heat, even thereby electric heating exchange cause and the increase of humidity also can improve humidification efficiency.
In addition, when operation dehumidifying makes extraneous gas and carries out the electric heating exchange and reduce after the temperature and humidity of extraneous gas between the ventilation air of indoor discharge, binding domain 12A to rotor 12 imports extraneous gas, thereby the temperature of the extraneous gas that imports to rotor 12 binding domain 12A is reduced, can promote the absorption of moisture among the binding domain 12A and increase adsorbance.Therefore, temperature or the humidity with extraneous gas has nothing to do and can dehumidify when keeping indoor temperature.
Followingly second embodiment of the present invention is described with reference to Fig. 2 to Fig. 3.And, use identical symbol for the constituent element identical with described embodiment.In addition, omit the explanation of repeating part.
As shown in Figure 2, air dehumidifying and humidifying apparatus 30 is provided with first humidity sensor 31 in the upstream of first passage 10 rotors 12 of Humidifying dehumidifying portion 2, and the downstream of rotor 12 is provided with second humidity sensor 32.The output of this first and second humidity sensor 31,32 is connected in control device 33, and by this first and second humidity sensor 31,32 and control device 33 and constitute the adsorbance control module.
Below mainly with reference to the effect of the flowchart text present embodiment of Fig. 3.
At first, when carrying out general humidification operation or dehumidifying operation (being "Yes" among the step S101), move respectively and adsorb with ventilating fan 14 and regeneration ventilating fan 18 (step S102).Its result realizes absorption and realize regeneration in first passage 10 in second channel 11 as first embodiment, thereby humidifying air or dehumidified air is to indoor discharge.When finishing operation (being "Yes" among the step S105), make absorption out of service with ventilating fan 18 and rotor 12 with ventilating fan 14 and regeneration.
In contrast, when not carrying out humidification and dehumidifying operation, (be "No" among the step S101), obtain the psychrometric difference (step S103) that is absorbed into outlet by first and second humidity sensor 31,32 shown in Fig. 2 and control device 33.The humidity of the extraneous gas that the psychrometric difference that is absorbed into outlet is detected by first humidity sensor 31 deducts the difference of the humidity of the extraneous gas (absorbed air) that second humidity sensor 32 detected and calculates.When this psychrometric difference that is absorbed into outlet surpasses predetermined value, for example psychrometric difference be the upstream first humidity sensor, 31 detected values 10% (be "Yes" among the step S103) when above, only operation absorption stops regeneration ventilating fan 18 with ventilating fan 14 (step S104), thus the beginning adsorption operations.At this moment, owing to rotor 12 is rotating, thereby moisture is adsorbed to whole rotor 12 in first passage 10.Air quantity air quantity identical, in the time of also can moving than humidification when at this moment, absorption can move with humidification with the air quantity of ventilating fan 14 is little.And, execution in step S104 repeatedly in step S101, up to the psychrometric difference that is absorbed into outlet less than predetermined value (for example 10% of first humidity sensor, 31 detected values of upstream), when the psychrometric difference that is absorbed into outlet (is "No") during less than predetermined value among the step S103, absorption is stopped with ventilating fan 14 and rotor and finishes operation (being "Yes" among the step S105).
Carry out absorption as mentioned above and move when reruning afterwards the humidification operation, beginning humidification operation under the state of rotor 12 abundant adsorption moistures, and to indoor supply regeneration air.Thus, at once just can be after the operation of beginning humidification to indoor supply by the regeneration air of abundant humidification.And, also can stably supply by the regeneration air of abundant humidification after process is fixed time.
Select enforcement to adsorb situations such as operation after the humidification operation or the user by not shown method of operating for finishing in selection the opportunity of implementing this absorption operation according to the user.And, the daytime user also is set not in the indoor time period in the timer that can be provided with in control device 33, and makes it implement the absorption operation automatically in this time period.In addition, can also set automatically or according to the user in time period that the user go to bed at night and implement the absorption operation.When the electricity charge at night are more cheap than daytime, can save operating cost.
According to present embodiment, owing to before humidification operation, can in advance moisture be stored in the rotor 12, thereby can be promptly when the beginning humidification moves be fed to the regeneration air of high humility indoor.And,, can keep the state of high humidification efficiency for a long time because it is more to be adsorbed onto the moisture of rotor 12.Identical as for other effects with above-mentioned embodiment.In addition, the threshold value that is absorbed into the outlet psychrometric difference among the step S103 is not limited to 10%, can and the place be set according to its air dehumidifying and humidifying apparatus 30 and use optimal value.
At this, if only second humidity sensor 32 is set, and before humidity is for absorption operation beginning 80% the stopping to adsorb when above and move of humidity, also can obtain identical effect and effect.
In addition, temperature sensor also can be set substitute first and second humidity sensor 31,32, and finish the absorption operation according to the temperature difference between rotor 12 upstream and downstreams.Rise to some extent with respect to the temperature before the absorption owing to learn the temperature of the absorbed air of moisture after being adsorbed, thereby control device 33 is in control when temperature difference that temperature sensor detected reaches certain value and finish absorption and move.And, can also in control device 33, be provided with and measure the absorption operation timer of beginning used time afterwards, through being used to stop the absorption operation after the preset time.In addition, the sensor that detects outdoor temperature humidity can also be set, stop the absorption operation in limited time when the outdoor temperature reduction reaches adsorption sector.
In addition, the present invention is not limited to aforesaid each embodiment, can extensive use.
For example, as long as Humidifying dehumidifying portion 2 can dry type carry out absorption and humidification, then various structures can.Especially, absorption is not limited to embodiment with the ventilating fan 14 or the position of regenerating with ventilating fan 18, can substitute among the ventilating fan 14,18 at least one with electrical heat exchanger 3 fans.And the damping parts can substitute rotor 12 with intermittent duty and quadrangle in associativity ground.
In addition, also can distribution duct, it is indoor that the absorbed air of dehumidifying in first passage 10 can be fed to, thus according to user's selection etc. optionally to the regeneration air of indoor discharge humidification and the absorbed air of dehumidifying.
In addition, the ventilation air is not limited to implement the room air of humidification or dehumidifying, can also be other house or dwelling house etc., so long as get final product with respect to the outdoor space air of cutting apart.
Electrical heat exchanger 3 can also be set in aspirating air pipe 5A, in air refreshing tube 6, channel converter is set, thereby when dehumidifying,, when humidification, supply the ventilation air by the electrical heat exchanger 3 of aspirating air pipe 5B by the electrical heat exchanger 3 supply ventilation air of aspirating air pipe 5A.
According to the present invention, during humidification, the air that temperature is higher than the extraneous gas temperature is fed to heat exchanger, makes the extraneous gas of being heated by this air flow into the damping parts and carries out humidification; During dehumidifying, the air that temperature is lower than the extraneous gas temperature is fed to heat exchanger, make the extraneous gas that cools off by this air flow into the damping parts and carry out dehumidifying, thereby can improve humidification efficiency and dehumidification rate, can reduce input power when especially in second channel, heater being set.At this, be the air that is fed to heat exchanger if use from the ventilation air of indoor discharge, then can when carrying out indoor ventilation, carry out humidification or dehumidifying, thereby effectively use the heat of ventilation air and improve humidification efficiency or dehumidification rate.Therefore, when humidification moves, also can fully carry out humidification even the extraneous gas temperature is low; When the dehumidifying operation, also can fully carry out dehumidifying even the extraneous gas temperature is higher.And,, can effectively use the heat that moisture comprised in the extraneous gas or in the room air if when using electrical heat exchanger to use as heat exchanger.And, the adsorbance control module is set, can be before carrying out the operation of general humidification in the damping parts abundant adsorption moisture, thereby the humidification amount can improve the operation of beginning humidification time the or obtain stable humidification amount.When this absorption of execution moves, if, then can suitably control water adsorption amount to the damping parts temperature sensor or humidity sensor being set before and after the zone that the execution of damping parts is adsorbed in order to humidity variation or variations in temperature before and after the mensuration damping parts.
