    Hereinafter, embodiments of the present invention will be described with reference to the drawings. The following embodiments are essentially preferable examples, and are not intended to limit the scope of the present invention, its application, or its use.

Embodiment 1 of the Invention
<overall structure>
The humidity control apparatus (1) of the present embodiment is installed in the room (3) of the building (2) and controls the humidity (in this case, dehumidification) of the room (3). As shown in FIG. 1, the humidity control apparatus (1) includes a casing (10), a humidity control module (20), a fan (50), and a control unit (55).

    Inside the casing (10), an air passage (P) is formed which communicates the room (3) with the outside. A humidity control module (20) and a fan (50) are arranged in the air passage (P). The fan (50) sends indoor air (RA) or outdoor air (OA) to the humidity control module (20). The fan (50) is configured to switch the direction of air flow in the air passage (P) by switching the rotation direction by the control unit (55).

<Configuration of humidity control module>
As shown in FIG. 2, the humidity control module (20) includes a plurality of heat-strained members (21), an actuator (22), and a plurality of adsorbents (30).

    The thermostrictive member (21) is made of a thermostrictive material (Thermoelastic) that generates heat by applying a tensile force, which is a tension, and absorbs heat by releasing the application of the tensile force. Examples of the heat strain material include titanium (Ti) / nickel (Ni) based alloys (for example, shape memory alloys) and elastomer resins.

    In the case of an alloy of titanium (Ti) / nickel (Ni), as shown in FIG. 3, when a tensile force is applied to the heat strain member (21), the heat strain material constituting the heat strain member (21) is the parent phase. By changing the phase from the (austenite phase) to the martensite phase, the entropy is reduced, and the heat-strained member (21) itself is heated by that amount (I to II). When the thermal strain member (21) is brought into contact with the object to be heated while a tensile force is applied to the heat strain member (21), the heat of the heat strain member (21) is transmitted to the object to be heated (II to III). By doing so, the temperature of the thermostrictive member (21) is lowered. When the tensile force applied to the thermostrictive member (21) is removed (released), the martensite phase changes to the parent phase (austenite phase) (III to IV). At this time, if the thermal strain member (21) is thermally insulated, the temperature of the thermal strain member (21) decreases. When the object to be cooled is brought into contact with the heat-strained member (21) whose temperature has decreased, the heat of the object to be cooled is transferred to the heat-strained member (21) (IV to I).

    As shown in FIG. 2, each thermostrictive member (21) is a wire extending in the vertical direction, and is arranged in the horizontal direction at a predetermined interval. Each thermal strain member (21) has a lower end connected to the fixing member (28) and an upper end connected to the actuator (22).

    The actuator (22) applies a tensile force to the thermal strain member (21) (in this case, pulls the thermal strain member (21) upward). The actuator (22) is connected to the control unit (55), and the application of the tensile force to the thermal strain member (21) and the release thereof are controlled by the control unit (55).

    The adsorbent (30) adsorbs and desorbs moisture in the air, and has a main body (31) and an adsorbing layer (35) as shown in FIGS.

    The main body (31) is a substantially rectangular metal plate-like member that extends vertically between the fixing member (28) and the actuator (22), and faces each other at a predetermined interval. Are arranged to be.

    Each main body (31) is configured by two plate members (31a, 31b) that overlap in the thickness direction. An insertion hole (32) is formed through the two plate members (31a, 31b) in the vertical direction, and a thermal strain member (21) is inserted into the insertion hole (32). When a tensile force is applied to the inserted thermal strain member (21), the insertion hole (32) is directed upward (direction in which the tensile force is applied) to the insertion hole (32). It is formed so as to extend while sliding.

    The adsorption layer (35) is carried on the surface of the main body (31). The adsorption layer (35) is made of a material capable of adsorbing and desorbing moisture in the air. For example, zeolite, silica gel, activated carbon, hydrophilic or water-absorbing organic polymer material, carboxylic acid group or It is composed of a functional polymer material such as an ion exchange resin-based material having a sulfonic acid group or a temperature-sensitive polymer.

-Driving action-
The operation of the humidity control apparatus (1) of this embodiment will be described. In the humidity control apparatus (1), a dehumidifying operation for dehumidifying the room (3) is performed. In the dehumidifying operation, the moisture releasing operation and the moisture absorbing operation are alternately performed at predetermined time intervals.

<Moisturizing operation>
First, the moisture release operation will be described with reference to FIGS. 1 (A) and 5 (A).

    When the moisture releasing operation starts, the room air (RA) flows into the air passage (P) by the fan (50) and is sent to the humidity control module (20). At this time, in the humidity control module (20), the actuator (22) is driven, and a tensile force is applied upward to the thermal strain member (21).

    When a tensile force is applied to the heat strain member (21), the heat strain member (21) generates heat and expands upward. At this time, the thermostrictive member (21) is in sliding contact (contact) with the insertion hole (32) of the main body (31) of the adsorbent (30). Therefore, the heat of the thermostrictive member (21) moves to the adsorption layer (35) via the main body (31) (insertion hole (32)), and the adsorption layer (35) is heated. When the adsorption layer (35) is heated, moisture is desorbed from the adsorption layer (35). Then, moisture is given to the indoor air (RA) passing between the adsorbents (30) and the air is discharged to the outside, and the adsorbed layer (35) is regenerated.

<Hygroscopic operation>
Next, the moisture absorption operation will be described with reference to FIGS. 1B and 5B.

    When the moisture absorption operation is started, outdoor air (OA) flows into the air passage (P) by the fan (50) and is sent to the humidity control module (20). At this time, in the humidity control module (20), the tensile force applied to the thermal strain member (21) is released.

    When the tensile force applied to the heat strain member (21) is released, the heat strain member (21) absorbs heat and shrinks downward. At this time, the thermostrictive member (21) is in sliding contact (contact) with the insertion hole (32) of the main body (31) of the adsorbent (30). Therefore, the heat of the adsorption layer (35) moves to the thermal strain member (21) through the main body (31) (insertion hole (32)), and the adsorption layer (35) is cooled. When the adsorption layer (35) is cooled, the moisture in the outdoor air (OA) passing between the adsorbents (30) is adsorbed on the adsorption layer (35). Then, the air dehydrated by depriving the adsorption layer (35) is supplied to the room (3).

-Effect of Embodiment 1-
According to Embodiment 1, the adsorbent (30) carrying the adsorbing layer (35) is provided. And it was made to expand-contract, making the heat-strain member (21) slide-contact (contact) to the main-body part (31) of this adsorption body (30). In this way, heat is transferred from the thermostrictive member (21) to the adsorption layer (35) through the main body (31), and the adsorption layer (35) adsorbs and desorbs moisture in the air, The adsorption layer (35) can be prevented from peeling off due to the expansion and contraction of the strain member (21). As a result, it is possible to improve the sustainability of the adsorption function of the humidity control module (20).

    Further, according to the first embodiment, the thermostrictive member (21) is inserted into the insertion hole (32) of the main body (31) of the adsorbent (30) to be in sliding contact. This stabilizes the contact state between the heat-strained member (21) and the main body (31), and ensures heat transfer between the heat-strained member (21) and the main body (31). The adsorption capacity of the adsorption layer (35) can be reliably exhibited.

The moisture in outdoor air (OA) is adsorbed on the layer (35). Then, the air dehydrated by depriving the adsorption layer (35) is supplied to the room (3).

    On the other hand, in the lower processing chamber (12) where the moisture releasing operation is performed, room air (RA) is sent to the humidity control module (20). At this time, in the humidity control module (20), by applying a tensile force to the heat strain member (21), the heat strain member (21) generates heat, the adsorption layer (35) is heated, and the adsorption layer (35 Moisture is desorbed from). Then, the moisture is given to the room air (RA) and discharged to the outside, and the adsorption layer (35) is regenerated.

    During the second operation, indoor air (RA) is sent to the humidity control module (20) in the upper processing chamber (11) where the moisture release operation is performed.

The moisture in outdoor air (OA) is adsorbed on the layer (35). Then, the air dehydrated by depriving the adsorption layer (35) is supplied to the room (3).

    As described above, in this modification, the first operation and the second operation are alternately performed to regenerate the adsorption layer (35) in one processing chamber (11, 12) while the other processing chamber (11, 12). Since the air supplied to the room (3) is dehumidified by the adsorption layer (35), the room (3) can be dehumidified continuously.

    In the first humidity control section (20a), when the application of the tensile force to the heat strain member (21) is released, the heat strain member (21) absorbs heat and contracts upward. At this time, since the heat strain member (21) is in sliding contact (contact) with the heat transfer tube (31c), the heat of the adsorption layer (35) is heated through the heat transfer tube (31c) and the fin (31d). Moving to the strain member (21), the adsorption layer (35) is cooled. When the adsorption layer (35) is cooled, the moisture of outdoor air (OA) passing between the fins (31d) is adsorbed on the adsorption layer (35). Then, the air dehydrated by depriving the adsorption layer (35) is supplied to the room (3).

    On the other hand, in the second humidity control section (20b), when a tensile force is applied to the heat strain member (21), the heat strain member (21) generates heat and extends upward. At this time, since the heat strain member (21) is in sliding contact (contact) with the heat transfer tube (31c), the heat of the heat strain member (21) passes through the heat transfer tube (31c) and the fin (31d). Moving to the adsorption layer (35), the adsorption layer (35) is heated. When the adsorption layer (35) is heated, moisture is desorbed from the adsorption layer (35). The moisture is applied to the indoor air (RA) passing between the fins (31d) and discharged to the outside, and the adsorption layer (35) is regenerated.

<Second operation>
As shown in FIG. 12B, the second operation is performed while the large diameter portion (24b) of the cam (24) is in contact with the second movable plate (23b). When the large-diameter portion (24b) of the cam (24) contacts the second movable plate (23b), the entire movable housing (23) moves downward, and the thermal strain of the upper first humidity control portion (20a) While the tensile force is applied to the member (21), the application of the tensile force to the heat-strained member (21) of the lower second humidity control section (20b) is released.

    In the first humidity control section (20a), when a tensile force is applied to the heat strain member (21), the heat strain member (21) generates heat and extends downward. At this time, since the heat strain member (21) is in sliding contact (contact) with the heat transfer tube (31c), the heat of the heat strain member (21) passes through the heat transfer tube (31c) and the fin (31d). Moving to the adsorption layer (35), the adsorption layer (35) is heated. When the adsorption layer (35) is heated, moisture is desorbed from the adsorption layer (35). The moisture is applied to the indoor air (RA) passing between the fins (31d) and discharged to the outside, and the adsorption layer (35) is regenerated.

    On the other hand, in the second humidity control section (20b), when the application of the tensile force to the heat strain member (21) is released, the heat strain member (21) absorbs heat and contracts downward. At this time, since the heat strain member (21) is in sliding contact (contact) with the heat transfer tube (31c) of the adsorbent (30), the heat of the adsorption layer (35) is transferred to the heat transfer tube (31c) and the fin ( It moves to the thermostrictive member (21) via 31d), and the adsorption layer (35) is cooled. When the adsorption layer (35) is cooled, the moisture of outdoor air (OA) passing between the fins (31d) is adsorbed on the adsorption layer (35). Then, the air dehydrated by depriving the adsorption layer (35) is supplied to the room (3).

    In this way, by rotating the cam (24) of the actuator (22), the adsorption layer (35) is regenerated in one processing chamber (11, 12), while the other processing chamber (11, 12) Since the air supplied to (3) is dehumidified by the adsorption layer (35), the room (3) can be dehumidified continuously.
