Technical field

The present invention relates to a humidity control apparatus for adjusting the humidity of air, and more particularly to a humidity control apparatus having an adsorption element and a refrigerant circuit. Background art

DESCRIPTION OF RELATED ART Conventionally, as disclosed in Unexamined-Japanese-Patent No. 11-124,737, the humidity control apparatus using the rotor-shaped adsorption | suction element is known, for example. In this humidity control apparatus, a dehumidifying operation for supplying dehumidified air to a room and a humidifying operation for supplying humidified air to a room are performed by switching. The suction element is housed in a casing and is configured to be driven to rotate around its central axis. In addition, the adsorption element allows a part of the adsorption side air to pass therethrough, and the remaining part passes the regeneration side air heated by the electric heater.

In the dehumidifying operation of the humidity control device, the adsorption side air whose moisture has been deprived by a part of the adsorption element is supplied to the room. The remaining part of the adsorption element is regenerated by the heated regeneration air, and the regeneration air that has passed through the adsorption element is discharged outside the room. On the other hand, in the case of the humidification operation, the regeneration side air provided with the moisture desorbed from the adsorption element is supplied to the room, and the adsorption side air deprived of the adsorption element is discharged outside the room. Then, as the adsorbing element rotates, the portion that has absorbed the moisture is sequentially regenerated, and the regenerated portion sequentially absorbs the moisture, so that the dehumidifying operation or the humidifying operation is continuously performed.

In the above humidity control device, an electric heater is used as a heat source for heating the air on the regeneration side, but a heat pump may be used as a heat source instead. Normally, a refrigerant circuit constituting a heat pump is provided with two heat exchangers, one of which serves as an evaporator and the other serves as a condenser. In the heat exchanger that functions as a condenser, the regeneration-side air is heated by heat exchange with the refrigerant. On the other hand, the heat exchanger, which is the evaporator, The air on the adsorption side after passing through the element exchanges heat with the refrigerant.

During dehumidification, the adsorption side air dehumidified by the adsorption element is cooled by the evaporator and supplied into the room, while the regeneration side air is heated by the condenser to regenerate the adsorption element and discharged outside the room. . At the time of humidification, the regeneration-side air heated by the condenser is humidified by the adsorption element and supplied to the room, while the adsorption-side air that has given moisture to the adsorption air in preparation for humidification passes through the evaporator. It is discharged outside the room. By the way, if the outdoor temperature is lower than a predetermined value at the time of humidification, moisture in the air on the dehumidifying side causes frost formation on the evaporator, and drain water is generated in the evaporator during the defrost operation. As a result, drain water drops from this evaporator, causing a drop in the equipment casing and dropping water drops indoors. If the outdoor humidity is higher than a predetermined value during dehumidification, moisture that cannot be processed by the adsorption element becomes drain water of the evaporator, causing the same problem.

The present invention has been made in view of such problems, and an object of the present invention is to solve these problems caused by drain water generated in an evaporator when a refrigerant circuit is applied to a humidity control device. Is to eliminate. Disclosure of the invention

When the evaporator (second heat exchanger) (104) is defrosted due to dew on the (exchanger) (103) or the outdoor temperature is low during the humidification operation, it is defrosted. (Including defrost water) is generated, but this drain water can be treated in the equipment without discharging it as liquid in the equipment.

《Drain water treatment during dehumidification operation》

First, the treatment of the drain water during the dehumidifying operation will be described.

As shown in Fig. 9 (a), this humidity control device transfers the drain water (W) generated in the first heat exchanger (103) by the moisture in the first air during the dehumidifying operation to the second air path. It is configured to release into and evaporate.

Specifically, as shown by the arrow (A1), the drain water W is transferred between the regenerative heat exchanger (102) and the adsorbing element (81, 82) during the regenerating operation in the second air path. It is configured so that it can be supplied to With this configuration, the drain water (W) generated in the first heat exchanger (103) is heated by the regenerative heat exchanger (102) downstream of the regenerative heat exchanger (102). Contained in the second air and discharged outside the room. Therefore, the drain water (W) does not cause 鲭 in the equipment and the drain water (W) does not drop into the room.

The drain water (W) is directly supplied to the regenerative heat exchanger (102) in the second air path as shown by the arrow (A2), or as shown by the arrow (A3). In the second air path, it is supplied to the upstream side of the regenerative heat exchanger (102) (in the figure, it is upstream of the adsorption elements (81, 82) on the adsorption side, but it may be downstream). To do It is possible. Furthermore, the drain water (¾ is supplied to the downstream side of the adsorbing element (81, 82) during the regeneration operation in the path of the second air as indicated by the arrow (A4). Even in these cases, the drain water (W) does not cause 鲭 in the equipment and the drain water (W) does not drop into the room.

《Drain water treatment during humidification operation》

Next, the treatment of drain water (W) during the humidification operation will be described.

As shown in Fig. 9 (b), this humidifier controls the drain generated by performing the defrost operation when the first air passes through the second heat exchanger (104) and forms frost during the humidification operation. Water (W) is contained in the second air and supplied to the room as in the dehumidifying operation. Specifically, as shown by the arrow (B1), the drain water (W) is combined with the regenerative heat exchanger (102) and the adsorption element (81, 82) during the regenerating operation in the second air path. It is configured to be able to supply during. With this configuration, the drain water (W) generated in the second heat exchanger (104) is heated by the regenerative heat exchanger (102) downstream of the regenerative heat exchanger (102). It is contained in the second air and is supplied indoors. Therefore, the drain water (W) does not cause 鲭 in the equipment and the drain water (W) does not drop into the room.

The drain water (W) can be directly supplied to the regenerative heat exchanger (102) in the second air path as shown by the arrow (B2), or as shown by the arrow (B3). Alternatively, it can be supplied to the upstream side of the regenerative heat exchanger (102) in the path of the second air. Further, the drain water (W) is configured to be supplied to the downstream side of the adsorption element (81, 82) during the regeneration operation in the path of the second air, as indicated by the arrow (B4). It is good. Even in these cases, the drain water (W) does not cause 鲭 in the equipment and the drain water (W) does not drop into the room.

《Modification of drain water treatment during humidification operation》

During the humidification operation, the drain water (W) may be returned to the first air on the adsorption side. In this case, specifically, as shown by the arrow (C) in FIG. 10, the drain water (W) generated in the second heat exchanger (104) by the moisture in the first air is converted into the first air Is supplied to the upstream side of the adsorption element (81, 82) that is performing the adsorption operation in the path. Then, the drain water (W) is contained in the first air and is adsorbed by the adsorption elements (81, ⁸² ). 03 00615

25 Therefore, in the same way as above, drain water (W) does not cause 鲭 in the equipment and drain water (W) does not drop into the room. Also, in this case, the amount of water adsorbed by the adsorption element (81, 82) used on the adsorption side increases, so that the amount of regeneration when the element (81, ⁸² ) is switched to the reproduction side increases. As a result, the humidification ability can be increased.

Effect of Embodiment 1

In the humidity control apparatus of the first embodiment, the drain water (W) generated in the first and second heat exchangers (103, 104) as evaporators is introduced into the second air path during the dehumidifying operation and the humidifying operation. In the humidifying operation, the liquid is evaporated in the second air, or is introduced into the path of the first air to be adsorbed by the adsorbing elements (81, 82). As a result, drain water W drops from the evaporator (10 ³ , 10), causing water to form inside the casing (10) or causing the casing (1

0), it is possible to prevent the problem that the indoor drain water (W) drops.

In addition, when the drain water (W) is introduced into the path of the first air during the humidifying operation and is adsorbed by the adsorbing element (81, 82), the configuration shown in Fig. 10 is used. Since this moisture can be given to the second air, the humidification amount can be increased. Further, in the first embodiment, since the batch-type treatment is performed by using the two adsorption elements (81, 82), the humidification operation and the dehumidification operation can be performed continuously. Since the air is used as the cooling fluid for the first air, it is possible to prevent the temperature of the blowout from increasing during the dehumidifying operation.

[Embodiment 2]

The humidity control apparatus of the first embodiment is configured so that heat of adsorption generated when adsorbing moisture of the first air is recovered by the cooling fluid, but the humidity control apparatus is configured as shown in FIG. Alternatively, a configuration using an adsorption element (81, 82) that does not recover adsorption heat may be used. In this case, the suction elements (81, 82) are not shown, but, for example, a flat plate member (83) and a corrugated plate member (84) are alternately stacked to form a rectangular parallelepiped block, and all of the corrugated plate members ( By aligning the direction of the ridge line of (84), only the humidity control side passage (85) is provided. Then, in the adsorption element ⁽⁸ 1,82), the adsorbent is applied to both sides of double-sided and corrugated plate members of the plate member (8 ³⁾ (84).

In this configuration, during the dehumidifying operation shown in FIG. When passing through one of (1, 82), moisture is absorbed and dehumidified, and the first air is cooled by the first heat exchanger (103) and supplied to the room. Further, the second air is heated in the regenerative heat exchanger (102), passes through the other of the adsorption elements (81, 82), desorbs moisture from the elements (81, 82), and removes water from the adsorption elements (81, 82). 81, 82). The second air is released outside the room after regenerating the adsorption element. Then, the adsorption side and the regeneration side are alternately switched, and the continuous operation is performed.

Further, after the second air was heated pressurized with regenerative heat exchanger (103) during the humidifying operation shown in FIG. 1 1 (b), passes through one of the adsorption element (81, 82), the adsorption element ⁽⁸ 1 , 82) to be humidified and supplied indoors. In addition, when the first air passes through the other of the adsorption elements (81, 82), moisture is adsorbed by the adsorption elements (81, 82), and the first air exchanges heat with the refrigerant in the second heat exchanger (104). It is cooled and released outside the room.

In the above configuration, when the first heat exchanger (103), which is an evaporator, forms dew during the dehumidifying operation and drain water is generated, the drain water (W) is discharged into the second air passage and evaporated. I do.

Specifically, as shown by the arrow (A1), the drain water (W) flows through the second air path through a drain pan (71), a drain pump (72), and a drain pipe (73). Is supplied between the regeneration heat exchanger (102) and the adsorption element (81, 82) during the regeneration operation. With this configuration, the drain water (¾) generated in the first heat exchanger (103) is the second air heated by the regenerative heat exchanger (102) downstream of the regenerative heat exchanger (102). Therefore, the water is not discharged from the room because of the drain water (W), and the drain water (W) does not drop into the room.

The drain water (W) is supplied directly to the regenerative heat exchanger (102) in the second air path as shown by the arrow (A2) or (2) It can be supplied to the upstream side of the regenerative heat exchanger (102) in the path of air. It is also possible to supply it during the regeneration operation in the path of the second air as shown by the arrow (A4). It can also be supplied downstream of the adsorption element (81, 82). Even in these cases, the drain water (W) does not cause 原因 in the equipment, nor does the drain water (¾) drop into the room.

Further, when drain water (W) is generated in the second heat exchanger (104), which is an evaporator during the humidification operation, the drain water W is similarly discharged into the path of the second air and evaporated. 3/00615

27 Specifically, as shown by the arrow (B1), the drain water (W) is connected to the regenerative heat exchanger (102) and the adsorption element (81, 82) during the regenerating operation in the path of the second air. ). With this configuration, the drain water (W) generated in the second heat exchanger (104) is downstream of the regenerative heat exchanger (102), and is discharged from the second heat exchanger (102). It is contained in air and is supplied indoors. Therefore, no water is generated in the equipment due to the drain water, and the drain water (W) does not drop into the room.

The drain water (W) is supplied directly to the regenerative heat exchanger (102) in the path of the second air, as shown by the arrows of the signs (B2) and (B3), or in the path of the second air. It is possible to supply the gas to the upstream side of the regenerative heat exchanger (102) with the adsorber (81, 81) during the regenerating operation in the path of the second air as shown by the arrow (B4). It is also possible to supply to downstream side of (82). Even in these cases, the drain water (W) does not cause 鲭 in the equipment and the drain water (W) does not drop into the room.

Furthermore, during the humidification operation, the drain water W is supplied to the upstream side of the adsorption elements (81, 82) in the first air path as shown by the arrow (C) in FIG. 11 (b). Is also good. In this case, the amount of water adsorbed by the adsorbing element (81, 82) on the adsorbing side increases, so that when the adsorbing element (81, 82) is switched to the regenerating side, the amount of humidification of the second air is increased. It becomes possible.

[Embodiment 3]

In Embodiment 3 of the present invention, as shown in FIG. 12, instead of using the two adsorption elements (81, 82) alternately on the adsorption side and the regeneration side and using them, an adsorption element formed in a rotor shape (hereinafter, referred to as the adsorption element) is used. This is an example in which (90) is used.

The suction rotor (90) is configured to rotate continuously or intermittently about a rotation axis (91). The suction rotor (90) is formed by making the suction element (81, 82) of the second embodiment into a disk shape, and has an air passage for removing and humidifying air along the axial direction. The suction rotor (90) is disposed so as to extend over the first air side air flow path and the second air side air flow path. In the illustrated example, the cooling-side passage described in the first embodiment is not provided in the suction rotor (90). However, for example, the cooling-side passage may be provided along the radial direction of the suction rotor.

In this configuration, as shown in Fig. 12 (a), the first air is sucked during the dehumidifying operation. Moisture is absorbed and dehumidified when passing through a part of the landing rotor (90), and the first air is cooled by the first heat exchanger (103) and supplied to the room. After the second air (RA) is heated in the regenerative heat exchanger (102), it passes through another part of the adsorption rotor (90), and desorbs water from the adsorption rotor (90). Regenerate suction rotor (90). The second air is released outside the room after regenerating the adsorption rotor (90).

As the suction rotor (90) rotates, the portion performing the suction operation and the portion performing the regeneration operation change continuously or intermittently. For this reason, the portion that has adsorbed moisture can be reused for re-adsorption after regenerating, thereby enabling continuous operation.

During the dehumidifying operation, when the first heat exchanger (103) is dewed to generate drain water (W), the drain water (W) is discharged into the second air path and evaporates. For this reason, as in the first and second embodiments described above, the humidity control device transfers the drain water (W) to the regenerative heat exchanger (102) in the path of the second air as shown by the arrow (A1). ) And the suction rotor (90).

In addition, the humidity control device supplies the drain water W directly to the regenerative heat exchanger (102) in the path of the second air as shown by the arrow (A2) or the drain water W as shown by the arrow (A3). In this way, it is also possible to supply to the upstream side of the regenerative heat exchanger (102) in the path of the second air. Further, the drain water (W) may be configured to be supplied to the downstream side of the adsorption rotor (90) in the path of the second air as indicated by an arrow (A4). On the other hand, during the humidification operation, as shown in Fig. 12 (b), the second air is heated by the regenerative heat exchanger (102) and then passes through a part of the adsorption rotor (90). As a result, the second air absorbs the moisture of the suction rotor (90), is humidified, and is supplied indoors. In addition, when the first air passes through another part of the adsorption rotor (90), moisture is adsorbed by the adsorption rotor (90), and after the first air exchanges heat with the second heat exchanger (104), the outdoor air is removed. Released to In the humidifying operation, the humidifier operates such that the first air passes through the second heat exchanger (104), and the drain water (W) generated by the first air passes through the second heat exchanger (104). Is configured. Specifically, the drain water is supplied between the regenerative heat exchanger (102) and the adsorption rotor (go) in the path of the second air as indicated by the arrow (B1). The drain water (W) is supplied directly to the regenerative heat exchanger (102) in the second air path as indicated by the arrow (B2), or may be indicated by the arrow (B3). Five

29, it is possible to supply to the upstream side of the regenerative heat exchanger (102), or to supply to the downstream side of the adsorption rotor (90) as shown by the arrow (B4). Further, the drain water (¾) may be discharged into the path of the first air and evaporated during the humidification operation as shown by an arrow (C).

Also in the present embodiment, the drain water (W) generated in the first heat exchanger (103) during the dehumidifying operation is included in the second air and discharged outside the room. Drain water generated in the second heat exchanger (104) during the humidification operation is supplied to the first air or the second air. Therefore, the drain water (W) does not cause 鲭 in the equipment and the drain water (W) does not drop into the room.

However, the present invention is applicable to a device that performs only the dehumidifying operation or only the humidifying operation. However, it is possible to prevent problems related to drain water (W). Industrial applicability
