    Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

<Embodiment 1>
A first embodiment of the present invention will be described. As shown in FIG. 1, the humidity control apparatus (1) according to the first embodiment includes an absorbent circuit (10) and a temperature control module (30). The humidity control device (1) dehumidifies or humidifies the room while ventilating it. The humidity control device (1) has an air supply passage (2) for supplying outdoor air to the room and an exhaust passage (3) for discharging indoor air to the outside. An air supply side module (20) is installed in the air supply passage (2), and an exhaust side module (21) is installed in the exhaust passage (3).

    In the absorbent circuit (10), the pump (11), the temperature control module (30), the supply side module (20) and the exhaust side module (21) are connected by a liquid pipe (12), and the liquid absorbent circulates. It is configured to As the liquid absorbent, for example, an aqueous lithium chloride solution is used. The air supply side module (20) and the exhaust side module (21) are a moisture releasing part that releases the moisture of the liquid absorbent into the air through the moisture permeable membrane (26), or the moisture in the air is a moisture permeable membrane ( 26) constitute a moisture absorption part that absorbs into the liquid absorbent.

    The air supply side module (20) and the exhaust side module (21) constitute a humidity control module (28). As shown in FIG. 2, each module (20, 21) includes a plurality of first header parts (22), a second header part (23), and a plurality of modules interposed between the header parts (22, 23). Humidity control pipe (24). Absorbing liquid pipes (22a, 22b) connected to the absorbent circuit (10) are connected to the first header part (22) and the second header part (23), respectively. Between the first header part (22) and the second header part (23), an air passage (P) that passes around the humidity control pipe (24) is formed. The air supply side module (20) and the exhaust side module (21) constitute a humidity control unit according to the present invention.

    The humidity control pipe (24) has an outer peripheral surface constituted by a moisture permeable membrane (26), and forms an absorbent passage (27) through which the liquid absorbent flows. The moisture permeable membrane (26) is a membrane that allows water vapor to pass through without passing through the liquid absorbent. As the moisture permeable membrane (26), for example, a hydrophobic porous membrane made of a fluorine resin such as PTFE (polytetrafluoroethylene, tetrafluoroethylene resin) can be used. In the humidity control pipe (24), moisture is transferred between the air flowing through the air passage (P) and the liquid absorbent flowing through the absorbent passage (27).

    As shown in FIGS. 3 and 4, the temperature control module (30) is for heating or cooling the liquid absorbent in the absorbent circuit (10). The temperature control module (30) has one casing (31), and a heat source element (32) and a belt conveyance device (33) are accommodated in the casing (31).

    The casing (31) is formed in a rectangular box, and an absorbent passage (41, 42) is formed therein. The inside of the casing (31) is configured such that the liquid absorbent flows from the near side to the far side in FIG. The inside of the casing (31) is partitioned up and down by an upper and lower partition plate (40), and an upper absorbent passage (41) and a lower absorbent passage (42) are formed. And the opening for arrange | positioning a belt conveying apparatus (33) is formed in the up-and-down partition plate (40).

    The heat source element (32) is made of a material that generates heat by applying a tensile force and absorbs heat by releasing the tensile force (hereinafter referred to as a heat strain material). Examples of the heat strain material include titanium (Ti) / nickel (Ni) based alloys (for example, shape memory alloys) and elastomer resins.

    As shown in FIG. 5, for example, in a titanium (Ti) / nickel (Ni) alloy, when a tensile force is applied, the phase changes from a parent phase (austenite phase) to a martensite phase. At this time, if the thermostrictive material is insulated, the entropy decreases and the molecular kinetic energy increases. That is, the temperature of the heat strain material increases. When the thermal strain material is brought into contact with the object to be heated while a tensile force is applied to the heat strain material, the heat of the heat strain material is transmitted to the object to be heated. By doing so, the temperature of the thermostrictive material is lowered. When the tensile force applied to the thermostrictive material is removed (released), the phase changes from the martensite phase to the parent phase (austenite phase). At this time, if the thermostrictive material is insulated, it takes energy from molecular motion in order to increase entropy. That is, the temperature of the heat strain material decreases. When the object to be cooled is brought into contact with the heat-strained material whose temperature has decreased, the heat of the object to be cooled is transferred to the heat-strained material.

    The belt conveying device (33) is a driving member (actuator) that conveys a plurality of fins (38) formed of a heat-strain material in the casing (31), and in the absorbent passage (41, 42). It switches between applying and releasing the tensile force to the thermostrictive material. The belt conveyance device (33) includes a guide rail (37), a belt (35), and two wheels (34, 34). The belt conveying device (33) constitutes a driving device according to the present invention.

    The wheel (34, 34) is a rotating body formed in a substantially cylindrical shape. The wheels (34, 34) are configured to be able to transport the belt (35). Two wheels (34, 34) are disposed side by side in the casing (31), and are configured to rotate counterclockwise.

    The belt (35) is formed as a sheet-like member, and includes an outer peripheral belt (35a) and an inner peripheral belt (35b).

    The inner peripheral belt (35b) is attached in contact with the two wheels (34, 34) and moves inside. That is, when the pair of wheels (34, 34) rotate counterclockwise, the inner peripheral belt (35b) moves leftward when passing through the upper absorbent passage (41) in the casing (31). When passing through the lower absorbent passage (42), it is transported in the right direction. The inner peripheral belt (35b) has protrusions (36) protruding outward from the portion where the heat strain material is formed at both ends in the width direction. This protrusion part (36) becomes a part which slides with the inner periphery rail (37b) mentioned later.

    The outer peripheral belt (35a) is attached to the inner peripheral belt (35b) via a heat-strained material and moves outside. That is, the outer peripheral belt (35a), the thermal strain material, and the inner peripheral belt (35b) are conveyed together. The outer peripheral belt (35a) has protruding portions (36) protruding outward from the portion where the heat strain material is formed at both ends in the width direction. This protrusion part (36) becomes a part which slides with the outer periphery rail (37a) mentioned later.

    As shown in FIG. 4, the guide rail (37) guides the outer peripheral belt (35a) and the inner peripheral belt (35b). The guide rail (37) is composed of an outer peripheral rail (37a) and an inner peripheral rail (37b).

    The outer peripheral rail (37a) is a rail member provided at both ends in the width direction of the outer peripheral belt (35a). The outer peripheral rail (37a) is configured to guide the outer peripheral belt (35a) by hooking a side end portion of the outer peripheral belt (35a) to a concave portion recessed outward.

    The inner peripheral rail (37b) is a rail member provided at both ends in the width direction of the inner peripheral belt (35b). The inner peripheral rail (37b) is configured to guide the inner peripheral belt (35b) by hooking a side end portion of the inner peripheral belt (35b) to a concave portion recessed outward.

    The distance between the outer peripheral rail (37a) and the inner peripheral rail (37b) differs between above and below the casing (31). Specifically, the distance between the outer rail (37a) and the inner rail (37b) increases above the casing (31) (upper absorbent passage (41)), but below the casing (31). In the (lower absorbent passage (42)), it is narrower.

    Each fin (38) is formed in a plate shape extending in the width direction (depth direction in FIG. 3) of the casing (31). Each fin (38) has one end attached to the outer peripheral belt (35a) and the other end attached to the inner peripheral belt (35b).

    When the wheels (34, 34) are simultaneously rotated, the outer peripheral belt (35a), the inner peripheral belt (35b), and the fin (38) are conveyed. When the upper absorbent passage (41) of the casing (31) is conveyed, the distance between the outer peripheral belt (35a) and the inner peripheral belt (35b) is increased, so that the heat constituting the fin (38) is increased. The strained material is pulled upward.

    On the other hand, when being conveyed through the lower absorbent passage (42) of the casing (31), the distance between the outer peripheral belt (35a) and the inner peripheral belt (35b) is reduced, so that the thermal strain constituting the fin (38). The tensile force on the material is released. That is, in the casing (31), the upper absorbent passage (41) is formed in a region for heating the liquid absorbent (that is, the upstream side of the liquid absorbent in the exhaust side module (21)), and the lower absorbent is formed. The passage (42) is formed in a region for cooling the liquid absorbent (that is, upstream of the liquid absorbent in the supply side module (20)).

    As described above, the inside of the casing (31) is an upper absorbent passage (41) and a lower absorbent passage (42). Accordingly, the heat source element (32) is disposed in the absorbent passage (41, 42), and the surface thereof is in contact with the liquid absorbent flowing through the absorbent passage (41, 42). That is, the heat strain material of the heat source element (32) is surrounded by the liquid absorbent flowing through the absorbent passage (41, 42).

In the humidity control apparatus (1) during the dehumidifying operation, when the wheels (34, 34) of the temperature control module (30) are simultaneously rotated, the heat strain material in the upper absorbent passage (41) is pulled. This heat-strained material dissipates heat to the liquid absorbent flowing in the surrounding absorbent passage (41). On the other hand, when being conveyed through the lower absorbent passage (42) of the casing (31), the distance between the outer peripheral belt (35a) and the inner peripheral belt (35b) is reduced, so that the thermal strain constituting the fin (38). The tensile force on the material is released. This heat-strained material absorbs heat from the liquid absorbent flowing in the surrounding absorbent passage (41).

    In the humidity control device (1), the pump (11) is operated to circulate the liquid absorbent. The liquid absorbent that has flowed out of the pump (11) flows through the upper absorbent passage (41), absorbs heat from the thermostrictive material, and is heated. Then, the liquid absorbent heated by the temperature control module (30) flows through the humidity control pipe (24) of the exhaust side module (21) (see FIG. 3). In the exhaust side module (21), moisture in the liquid absorbent is sucked from the room, flows through the exhaust passage (3), and is released to the air flowing through the air passage (P). The liquid absorbent having a high concentration as described above is transported to the pump (11) and flows through the lower absorbent passage (42) of the temperature control module (30).

    On the other hand, the liquid absorbent flowing in the lower absorbent passage (42) dissipates heat to the heat strain material and is cooled. Then, the liquid absorbent cooled by the temperature control module (30) flows through the humidity control pipe (24) of the air supply side module (20) (see FIG. 3). In the air supply side module (20), the moisture in the air that is sucked in from the outside and flows through the air supply passage (2) and flows through the air passage (P) passes through the moisture permeable membrane (26) of the humidity control pipe (24). To be absorbed into the liquid absorbent. The air dehumidified by applying moisture to the liquid absorbent is supplied into the room via the air supply passage (2). The liquid absorbent absorbs moisture in the humidity control pipe (24) of the supply side module (20) and becomes a low concentration.

<Dehumidifying operation>
The dehumidifying operation of the humidity control apparatus (1) will be described with reference to FIG. FIG. 15A shows a state of the first dehumidifying operation in which the dehumidifying operation is performed by the first unit (81) while the humidifying operation is performed by the second unit (82).

The liquid absorbent discharged from the pump (11) flows into the absorbent space (114) of the lower header (113) of the second humidity control module (86) in the second unit (82). Then, the liquid absorbent flowing through the lower header (113) flows into each absorbent passage (27). The liquid absorbent flowing into the absorbent passage (27) is heated by the heat strain material. In the second air passage (79), exhaust (that is, indoor air exhausted to the outside) flows. In the second humidity control module (86), part of the water contained in the liquid absorbent becomes water vapor, passes through the moisture permeable membrane (26), and is given to the exhaust flowing through the second air passage (79). The water vapor imparted to the exhaust is discharged together with the exhaust from the second outdoor port (77). Thus, in the second humidity control module (86), a part of the water contained in the liquid absorbent in the absorbent passage (27) passes through the moisture permeable membrane (26) and is given to the exhaust. Therefore, in the second humidity control module (86), the concentration of the liquid absorbent gradually increases while passing through the absorbent passage (27).

    The high-concentration liquid absorbent flowing out from the upper header (112) of the second humidity control module (86) flows into the absorbent space (114) of the lower header (113) of the first humidity control module (85).

In the first air passage (78) of the first humidity control module (85), air supply (that is, outdoor air supplied to the room) flows. In the first humidity control module (85), water vapor contained in the supply air passes through the moisture permeable membrane (26) and is absorbed by the liquid absorbent flowing through the absorbent passage (27). The air supply dehumidified while passing through the first air passage (78) of the first humidity control module (85) is then supplied into the room from the first indoor port (74). Thus, in the first humidity control module (85), part of the water vapor contained in the supply air in the first air passage (78) passes through the moisture permeable membrane (26) and is absorbed by the liquid absorbent. . Therefore, in the first humidity control module (85), the concentration of the liquid absorbent gradually decreases while passing through the absorbent passage (27). The low-concentration liquid absorbent flowing out from the upper header (112) of the first humidity control module (85) is sucked into the pump (11) and sent out toward the second humidity control module (86).

    The liquid absorbent discharged from the pump (11) flows into the absorbent space (114) of the lower header (113) of the second humidity control module (86). Then, the liquid absorbent flowing through the lower header (113) flows into each absorbent passage (27). The liquid absorbent flowing into the absorbent passage (27) is cooled by the heat strain material. In the second air passage (79), air supply (that is, outdoor air supplied to the room) flows. In the second humidity control module (86), water vapor contained in the supply air passes through the moisture permeable membrane (26) and is absorbed by the liquid absorbent flowing through the absorbent passage (27). The supply air deprived of water vapor is then supplied into the room from the second indoor port (75). As described above, in the second humidity control module (86), a part of the water vapor contained in the supply air of the second air passage (79) passes through the moisture permeable membrane (26) and is absorbed by the liquid absorbent. . Accordingly, in the second humidity control module (86), the concentration of the liquid absorbent gradually decreases while passing through the absorbent passage (27).

    The low-concentration liquid absorbent flowing out from the upper header (112) of the second humidity control module (86) flows into the absorbent space (114) of the lower header (113) of the first humidity control module (85). Then, the liquid absorbent flowing through the lower header (113) flows into each absorbent passage (27). The liquid absorbent flowing into the absorbent passage (27) is heated by the heat strain material. In the first air passage (78), exhaust (that is, indoor air exhausted to the outside) flows. In the first humidity control module (85), part of the water contained in the liquid absorbent becomes water vapor, passes through the moisture permeable membrane (26), and is given to the exhaust flowing through the first air passage (78). The exhaust gas that has been humidified while passing through the first air passage (78) is then discharged from the first outdoor port (76) to the outside. Thus, in the first humidity control module (85), a part of the water contained in the liquid absorbent in the absorbent passage (27) passes through the moisture permeable membrane (26) and is given to the exhaust. Therefore, in the first humidity control module (85), the concentration of the liquid absorbent gradually increases while passing through the absorbent passage (27). The high-concentration liquid absorbent flowing out from the upper header (112) of the first humidity control module (85) is sucked into the pump (11) and sent out toward the second humidity control module (86).

<Humidification operation>
The humidification operation of the humidity control device (1) will be described with reference to FIG. FIG. 16A shows the state of the first humidifying operation in which the humidification operation is performed by the first unit (81) while the dehumidifying operation is performed by the second unit (82).

The small diameter portion (98) of the first cam (95) comes into contact. By carrying out like this, the load of a 1st movable plate (91a) is applied with respect to the thermostrictive material of a 1st temperature control module (83), and tensile force is provided. On the other hand, in the heat strain material of the second temperature control module (84), the load of the second movable plate (91b) is supported by the second cam (96), and the tensile force is released.

    The liquid absorbent discharged from the pump (11) flows into the absorbent space (114) of the lower header (113) of the second humidity control module (86). Then, the liquid absorbent flowing through the lower header (113) flows into each absorbent passage (27). The liquid absorbent flowing into the absorbent passage (27) is cooled by the heat strain material. In the second air passage (79), exhaust (that is, indoor air exhausted to the outside) flows. In the second humidity control module (86), water vapor contained in the exhaust gas passes through the moisture permeable membrane (26) and is absorbed by the liquid absorbent flowing through the absorbent passage (27). The exhaust gas deprived of water vapor is then discharged from the second outdoor port (77) to the outside. Thus, in the second humidity control module (86), a part of the water vapor contained in the exhaust of the second air passage (79) passes through the moisture permeable membrane (26) and is absorbed by the liquid absorbent. Accordingly, in the second humidity control module (86), the concentration of the liquid absorbent gradually decreases while passing through the absorbent passage (27).

    The low-concentration liquid absorbent flowing out from the upper header (112) of the second humidity control module (86) flows into the absorbent space (114) of the lower header (113) of the first humidity control module (85). Then, the liquid absorbent flowing through the lower header (113) flows into each absorbent passage (27). The liquid absorbent flowing into the absorbent passage (27) is heated by the heat strain material. In the first air passage (78), air supply (that is, outdoor air supplied to the room) flows. In the first humidity control module (85), a part of the water contained in the liquid absorbent becomes water vapor, passes through the moisture permeable membrane (26), and is given to the supply air flowing through the first air passage (78). . The air supply humidified while passing through the first air passage (78) is then supplied into the room from the first indoor port (74). Thus, in the first humidity control module (85), a part of the water contained in the liquid absorbent in the absorbent passage (27) permeates the moisture permeable membrane (26) and is given to the supply air. Therefore, in the first humidity control module (85), the concentration of the liquid absorbent gradually increases while passing through the absorbent passage (27). The high-concentration liquid absorbent flowing out from the upper header (112) of the first humidity control module (85) is sucked into the pump (11) and sent out toward the second humidity control module (86).

    FIG. 16B shows a state of the second humidifying operation in which the humidifying operation is performed by the second unit (82) while the dehumidifying operation is performed by the first unit (81).

And the small diameter portion (98) of the second cam (96) contacts the second movable plate (91b). By carrying out like this, the load of a 2nd movable plate (91b) is applied with respect to the thermostrictive material of a 2nd temperature control module (84), and tensile force is provided. On the other hand, in the heat strain material of the first temperature control module (83), the load of the first movable plate (91a) is supported by the first cam (95), and the tensile force is released.

    Further, during the dehumidifying operation, the pump (11) of the absorbent circuit (10) is operated, and the liquid absorbent circulates in the absorbent circuit (10). The liquid absorbent discharged from the pump (11) flows into the absorbent space (114) of the lower header (113) of the second humidity control module (86). Then, the liquid absorbent flowing through the lower header (113) flows into each absorbent passage (27). The liquid absorbent flowing into the absorbent passage (27) is heated by the heat strain material. In the second air passage (79), air supply (that is, outdoor air supplied to the room) flows. In the second humidity control module (86), a part of the water contained in the liquid absorbent becomes water vapor, passes through the moisture permeable membrane (26), and is given to the supply air flowing through the second air passage (79). . The water vapor imparted to the supply air is supplied into the room from the second indoor port (75) together with the supply air. Thus, in the second humidity control module (86), a part of the water contained in the liquid absorbent in the absorbent passage (27) permeates the moisture permeable membrane (26) and is given to the supply air. Therefore, in the second humidity control module (86), the concentration of the liquid absorbent gradually increases while passing through the absorbent passage (27).

    The high-concentration liquid absorbent flowing out from the upper header (112) of the second humidity control module (86) flows into the absorbent space (114) of the lower header (113) of the first humidity control module (85). Then, the liquid absorbent flowing through the lower header (113) flows into each absorbent passage (27). The liquid absorbent flowing into the absorbent passage (27) is cooled by the heat strain material. In the first air passage (78), exhaust (that is, indoor air exhausted to the outside) flows. In the first humidity control module (85), water vapor contained in the exhaust gas passes through the moisture permeable membrane (26) and is absorbed by the liquid absorbent flowing through the absorbent passage (27). The exhaust gas dehumidified while passing through the first air passage (78) is thereafter discharged from the first outdoor port (76) to the outside. Thus, in the first humidity control module (85), part of the water vapor contained in the supply air in the first air passage (78) passes through the moisture permeable membrane (26) and is absorbed by the liquid absorbent. . Therefore, in the first humidity control module (85), the concentration of the liquid absorbent gradually decreases while passing through the absorbent passage (27). The low-concentration liquid absorbent flowing out from the upper header (112) of the first humidity control module (85) is sucked into the pump (11) and sent out toward the second humidity control module (86).

-Effect of Embodiment 2-
