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

Embodiment 1 of the Invention
Reference Example 1 of the present invention will be described.

-Overall configuration of the device-
FIG. 1 is a schematic diagram illustrating a state in which the air conditioner (1) according to Reference Example 1 is installed in a room (air-conditioning target space) (3) of a building (2). FIG. FIG. 1B shows the operating state of the heating operation (heat dissipating operation). The air conditioner (1) of Embodiment 1 is configured as a cooling only machine.

    The air conditioner (1) includes a casing (10), a cooling / heating module (20) housed in the casing (10), a fan (30) for flowing air to the cooling / heating module (20), and cooling / heating. And a switching control unit (35) for adjusting the tensile force applied to the module (20). The cooling / heating unit (5) is constituted by the cooling / heating module (20) and the switching control unit (35). Moreover, the indoor unit (U) is comprised by the casing (10) and the functional component provided in the inside.

    An air passage (P) for allowing the air introduced into the casing (10) to pass through the cooling and heating module (20) is formed in the casing (10). Specifically, the air sucked into the casing (10) from the room (3) is processed by the cooling and heating module (20) and returned to the room (3) when passing through the air passage (P). The air conditioner (1) is configured to intermittently cool the room (3) as will be described later, and when the cooling of the room (3) is stopped, the casing (10) When the air sucked into the air passes through the air passage (P), it takes heat from the cooling heating module (20) and is discharged to the outside again.

    In order to realize the above air flow, this air conditioner (1) is designed so that the intake air from the room, the air blown into the room, the air sucked from the outside, and the air blown out to the outside are not mixed. The inside of the casing (10) is partitioned by a partition plate or a damper not shown.

-Cooling and heating module-
As shown in FIG. 2A, the cooling and heating module (20) includes a thermal strain material (21) and an actuator (22) that applies a tensile force to the thermal strain material (21). ing. Note that the tensile force applied to the thermal strain material (21) constitutes the tension according to the present invention.

    The heat-strain material (21) is made of a shape memory alloy as an example, and heats the object by applying tension, while cooling the object by releasing the tension. Specifically, as shown in FIG. 21, when tension is applied to the thermostrictive material (21), the entropy is reduced by the phase change from the parent phase (austenite phase) to the martensite phase, and accordingly, The heat-strained material (21) itself is heated by generating heat (I to II). When the thermostrictive material (21) is brought into contact with the object to be heated while tension is applied to the thermostrictive material (21), the heat of the thermostrictive material (21) is transmitted to the object to be heated (II to III). By doing so, the temperature of the thermostrictive material (21) is lowered. When the tension applied to the thermostrictive material (21) is removed (released), the martensite phase changes to the parent phase (austenite phase) (from III to IV). At this time, if the heat-strained material (21) is insulated, the temperature of the heat-strained material (21) 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 (21) (IV to I).

    Therefore, as shown in FIG. 3A, when a tensile force is applied to the thermostrictive material (21), the thermostrictive material (21) generates heat. The temperature of the air that has passed through the cooling and heating module (20) rises. Conversely, as shown in FIG. 3B, when the tensile force applied to the heat strain material (21) is released, the heat strain material (21) absorbs heat. The temperature of the air that has passed through the cooling and heating module (20) decreases. In the air conditioner (1), the heating operation and the cooling operation of the heat strain material (21) are alternately performed, and the cooling operation using the cooling operation is intermittently performed.

  It should be noted that the capacity of the thermostrictive material (21) decreases when the capacity peak is exceeded from the start of operation during cooling heating. For this reason, the cooling operation and the heating operation are switched alternately.

    Specific examples of the heat strain material (21) include Ti / Ni / Cu alloys. In particular, when the composition range of the alloy is expressed, Ti having 40 to 80%, Ni 20 to 60%, and Cu 0 to 30% can be used.

    The actuator (22) is for applying a tensile force to the thermostrictive material (21). The actuator (22) is connected to the switching control unit (35), and the switching control unit (35) controls the application and release of the tensile force to the thermostrictive material (21).

−Tensile force application operation−
The switching control section (35) controls the actuator (22) to control the application and release of the tensile force to the thermostrictive material (21). In FIG. 22 (A to C), the switching control unit (35) changes the amount of tensile force applied to the thermostrain material (21) in the actuator (22), thereby generating heat from the thermostrain material (21). It is configured to adjust the amount and adjust the cooling heating capacity.

    Moreover, the said switching control part (35) changes the ratio of the thermostrain material (21) which provides a tensile force among the whole of each thermostrain material (21) in FIG.23 (AC). The heat generation capacity of the heat strain material (21) may be adjusted to adjust the cooling heating capacity.

    Furthermore, the switching control unit (35) is configured to adjust the heat generation amount of the thermostrictive material (21) by changing the time interval for repeating the cooling operation and the heating operation, thereby adjusting the cooling heating capacity. May be.

-Driving action-
In this air conditioner (1), only the cooling operation is performed.

    Specifically, in the cooling operation of FIG. 1A, the tensile force applied to the cooling / heating module (20) that has been heated is released. If it does so, the heat-strain material (21) of FIG.2, FIG.3 will be cooled and a cooling heating module (20) will absorb heat from air (room air (RA)). Accordingly, as shown in FIG. 1 (A), the indoor air (RA) introduced into the casing (10) is cooled, and the air is returned to the room as supply air (SA) to cool the room.

    During the heating operation of FIG. 1B, the rotation direction of the fan (30) is switched, and the outdoor air (OA) is taken into the casing (10) and processed by the cooling and heating module (20) before being discharged ( EA) is discharged outside the room. At this time, a tensile force is applied to the thermostrictive material (21) of the cooling and heating module (20). Then, the thermostrictive material (21) is heated and the cooling heating module (20) dissipates heat. Therefore, during this heating operation, the air heated through the cooling and heating module (20) is discharged outside the room.

In Reference Example 1 , the cooling operation is intermittently performed by repeatedly performing the cooling operation in FIG. 1A and the heating operation in FIG.

-Effects of Reference Example 1-
According to Reference Example 1 , the cooling and heating module (20) does not employ an elastic body such as rubber. Here, when an elastic body such as rubber is used for the cooling and heating module, a mechanism for expanding and contracting the elastic body is required, the structure of the air conditioner (1) is complicated, and the apparatus (1) is large. On the other hand, according to this embodiment, since the elastic body is not used for the cooling and heating module (20), it is possible to prevent the air conditioner (1) from becoming large and having a complicated structure. Can do.

Further, in Reference Example 1 , the heat generation amount of the thermostrictive material (21) can be adjusted and the cooling heating capacity can be adjusted, so that it is possible to operate according to the air conditioning load.

-Embodiment 1-
Embodiment 1 shown in FIG. 4 is configured to install two indoor units (U1, U2) in a room (3) to be air-conditioned. In the figure, the first indoor unit (U1) is installed on one of the opposing wall surfaces (the right wall surface in the figure), and the second indoor unit (U2) is installed on the other wall surface (the left wall surface in the figure). ing. Since the configuration of each indoor unit (U1, U2) is the same as that of the indoor unit (U) of the air conditioner (1) in FIG. 1, the description of the configuration of each indoor unit (U1, U2) is omitted. Note that air passages (P1, P2) are formed in the indoor units (U1, U2), respectively.

    FIG. 4A shows a state where the cooling operation is performed in the first indoor unit (U1) and the heating operation is performed in the second indoor unit (U2). In the first indoor unit (U1), the tensile force applied to the heat strain material (21) of the cooling and heating module (20) is released. Therefore, the cooling and heating module (20) of the first indoor unit (U1) absorbs heat, and the indoor air (RA) taken into the casing (10) is cooled. The cooled air is supplied to the room (3) as supply air (SA).

    On the other hand, in the second indoor unit (U2), the fan (30) rotates in the direction to discharge after the outdoor air (OA) is taken into the casing (10) and processed, and at the same time, the heat strain material of the cooling and heating module (20). A tensile force is applied to (21). Therefore, the outdoor air (OA) takes the heat of the cooling and heating module (20), and is discharged outside as outdoor air (EA).

    FIG. 4B shows a state in which the cooling operation is performed in the second indoor unit (U2) and the heating operation is performed in the first indoor unit (U1). In the second indoor unit (U2), the tensile force applied to the heat strain material (21) of the cooling and heating module (20) is released. Therefore, the cooling and heating module (20) of the second indoor unit (U2) absorbs heat, and the indoor air (RA) taken into the casing (10) is cooled. And the cooled air is supplied indoors as supply air (SA).

    On the other hand, in the first indoor unit (U1), the fan (30) rotates in the direction to discharge the outdoor air (OA) after taking it into the casing (10) and processing it, and at the same time, the heat strain material of the cooling and heating module (20) A tensile force is applied to (21). Therefore, the outdoor air (OA) takes the heat of the cooling and heating module (20), and is discharged outside as outdoor air (EA).

Thus, according to Embodiment 1, when one of the indoor units (U1, U2) cools the air and supplies the air to the room (3), the other indoor unit (U2, U1) ), The cooling operation can be continuously performed by alternately switching between the operation of FIG. 4A and the operation of FIG.

( Modification 1 of Embodiment 1 )

The configuration of each indoor unit (U1, U2) is the same as that of the air conditioner (1) shown in FIGS.

    FIG. 5A shows a state where the cooling operation is performed in the first indoor unit (U1) and the heating operation is performed in the second indoor unit (U2). In the first indoor unit (U1), the tensile force applied to the heat strain material (21) of the cooling and heating module (20) is released. Therefore, the cooling and heating module (20) of the first indoor unit (U1) absorbs heat, and the indoor air (RA) taken into the casing (10) is cooled. The cooled air is supplied to the room (3) as supply air (SA).

    On the other hand, in the second indoor unit (U2), the fan (30) rotates in the direction to discharge after the outdoor air (OA) is taken into the casing (10) and processed, and at the same time, the heat strain material of the cooling and heating module (20). A tensile force is applied to (21). Therefore, the outdoor air (OA) takes the heat of the cooling and heating module (20), and is discharged outside as outdoor air (EA).

    FIG. 5B shows a state in which the cooling operation is performed in the second indoor unit (U2) and the heating operation is performed in the first indoor unit (U1). In the second indoor unit (U2), the tensile force applied to the heat strain material (21) of the cooling and heating module (20) is released. Therefore, the cooling and heating module (20) of the second indoor unit (U2) absorbs heat, and the indoor air (RA) taken into the casing (10) is cooled. The cooled air is supplied to the room (3) as supply air (SA).

    On the other hand, in the first indoor unit (U1), the fan (30) rotates in the direction to discharge the outdoor air (OA) after taking it into the casing (10) and processing it, and at the same time, the heat strain material of the cooling and heating module (20) A tensile force is applied to (21). Therefore, the outdoor air (OA) takes the heat of the cooling and heating module (20), and is discharged outside as outdoor air (EA).

<< Embodiment 5 of the Invention >>
Embodiment 5 of the present invention will be described. Embodiment 5 shown in FIG. 24 relates to a specific configuration of the cooling and heating module (20). In the cooling and heating module (20) according to the fifth embodiment, the switching control unit (35) adjusts the position of the movable plates (41a, 41b), thereby adjusting the tensile force applied to the thermostrictive material (21). Switching between grant and release.

    As shown in FIG. 24, the cooling / heating module (20) according to the fifth embodiment includes first and second cooling / heating modules (20a, 20b). In FIG. 24, the first cooling / heating module (20a) is disposed on the right side, and the second cooling / heating module (20b) is disposed on the left side.

    Each of the cooling and heating modules (20a, 20b) includes a thermal strain material (21), an actuator (22), and a switching control unit (35). And between both the cooling heating modules (20a, 20b), it is divided into right and left by the partition plate (43).

    The thermal strain material (21) is formed in a wire shape extending vertically. This heat-strain material (21) is constituted by a shape memory alloy as an example, and heats the object by applying a tensile force, while cooling the object by releasing the tensile force. Specifically, as shown in FIG. 21, when a tensile force is applied to the thermostrictive material (21), the entropy decreases due to the phase change from the parent phase (austenite phase) to the martensite phase. The heat-strained material (21) itself is heated by heating (I to II). When the thermal strain material (21) is brought into contact with the object to be heated while a tensile force is applied to the heat strain material (21), the heat of the heat strain material (21) is transmitted to the object to be heated (II to III). By doing so, the temperature of the thermostrictive material (21) is lowered. When the tensile force applied to the thermostrictive material (21) is removed (released), the martensite phase changes to the parent phase (austenite phase) (III to IV). At this time, if the heat-strained material (21) is insulated, the temperature of the heat-strained material (21) 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 (21) (IV to I).

    The actuator (22) includes a fixed plate (40) as a fixed portion, first and second movable plates (41a, 41b) as movable portions, and first and second cams (46, 47) as displacement mechanisms. ) And a rotating shaft (39). The fixing plate (40) is formed in a substantially rectangular thin plate. The lower surface of the fixed plate (40) is divided into left and right regions by a partition plate (43), and one end of the thermostrictive material (21) of the first cooling heating module (20a) (first cooling heating unit) is divided into the right region. And one end of the thermostrictive material (21) of the second cooling / heating module (20b) (second cooling / heating unit) is attached to the left region.

    The said partition plate (43) partitions between the 1st and 2nd cooling heating modules (20a, 20b) right and left. The partition plate (43) is a member formed in a substantially T shape. The partition plate (43) is formed as a main body portion (44) formed in a rectangular thin plate extending downward in the orthogonal direction to the fixed plate (40), and a rectangular thin plate extending substantially parallel to the fixed plate (40). It is formed with a flange part (45). In the partition plate (43), the base end of the main body portion (44) is attached to the fixed plate (40), and the flange portion (45) is located at substantially the same height as the other end of the thermal strain material (21). Has been placed.

    The first and second movable plates (41a, 41b) are members for applying a tensile force to the thermal strain material (21), and are a first cooling heating module (20a) and a second cooling heating module (20b). ). The first movable plate (41a) is attached to the other end of the thermostrictive material (21) of the first cooling / heating module (20a), and is disposed to face the fixed plate (40). The second movable plate (41b) is attached to the other end of the thermostrictive material (21) of the second cooling / heating module (20b), and is disposed to face the fixed plate (40). A first air passage (42a) is formed between the first movable plate (41a) and the fixed plate (40), and a first air passage (42a) is formed between the second movable plate (41b) and the fixed plate (40). Two air passages (42b) are formed.

    The first and second movable plates (41a, 41b) are formed in a substantially rectangular thin plate and have a predetermined weight. For this reason, the first and second movable plates (41a, 41b) are given a load to the thermostrictive material (21) by the weight, and thereby a downward tensile force is applied to the thermostrictive material (21). . Therefore, the first and second movable plates (41a, 41b) have a weight capable of applying a tensile force to the heat strain material (21).

    The first and second cams (46, 47) are members formed in a substantially cylindrical shape extending in the width direction (depth direction in FIG. 24) of the first and second movable plates (41a, 41b). The first cam (46) is formed with a circular outer peripheral portion (48) and a small diameter portion (49) in which a semicircular portion is cut out. Further, the first cam (46) is attached so that the rotation shaft (39) is inserted through the center of the first cam (46) and is rotatable in the rotation direction of the rotation shaft (39). The second cam (47) is formed with a circular outer peripheral portion (48) and a small diameter portion (49) with a semicircular portion cut out. The second cam (47) is attached so that the rotation shaft (39) is inserted through the center of the second cam (47) and is rotatable in the rotation direction of the rotation shaft (39). A switching control unit (35) is connected to the rotating shaft (39), and the rotation positions of the first and second cams (46, 47) are controlled by the switching control unit (35).

    The first and second cams (46, 47) are 180 ° out of phase with each other on the left and right. That is, when the outer peripheral portion (48) of the first cam (46) comes into contact with the first movable plate (41a), the small diameter portion of the second cam (47) with respect to the second movable plate (41b). (49) is configured to contact. By carrying out like this, the load of a 2nd movable plate (47b) is applied with respect to the thermostrictive material (21) of a 2nd cooling heating module (20b), and tensile force is provided. For this reason, the thermostrictive material (21) of the second cooling and heating module (20b) generates heat, and the air flowing around it is heated. On the other hand, in the thermostrictive material (21) of the first cooling and heating module (20a), the load of the first movable plate (47a) is supported by the first cam (46), and the tensile force is released. For this reason, the heat-strain material (21) of the first cooling / heating module (20a) is cooled, and the air flowing around is cooled.

    Since the cooling and heating module (20) of the fifth embodiment can be put into practical use with a simple configuration and the module itself can be miniaturized, for example, by applying it to the air conditioner (1) of the first embodiment shown in FIG. In addition, the configuration of the air conditioner (1) can be prevented from becoming complicated, and at the same time, the device (1) can be downsized.

    Moreover, in this embodiment, since heating and cooling can be switched, it is suitable for the batch switching type air conditioner (1) in the above embodiment.

    A motor may be attached to each rotary shaft (39, 39), and the two cams (46, 47) may be controlled to have a phase of 180 °. May be linked to each other.

    Further, the shape of the cam is such that the ratio of the small diameter portion (49) and the outer peripheral portion (48) is different as shown in FIG. 25, or the rotational shaft (39) is simply eccentric as shown in FIG. Alternatively, as shown in FIG. 27, the curvature of the outer peripheral portion (48) may be varied and the rotation shaft (39) may be eccentric.

-Modification of Embodiment 5-
(Modification 1)
Next, Modification 1 of Embodiment 5 will be described. The first modification is different from the first embodiment in the configuration of the actuator (22). The switching control unit (35) is not shown.

    Specifically, as shown in FIG. 28, the first and second cams (46, 47) according to Modification 1 extend in the longitudinal direction of the first and second movable plates (41a, 41b).

The cam (46) is a member formed in a substantially cylindrical shape extending in the width direction (depth direction in FIG. 31) of the first and second movable plates (41a, 41b). The cam (46) is formed with a circular outer peripheral portion (48) and a small diameter portion (49) formed by cutting out a semicircular portion of the outer peripheral portion (48).

The rotating shaft (39) is disposed below the partition plate (43). First and second arms (51, 52) are attached to the rotating shaft (39). The rotating shaft (39) is connected to a stepping motor and is configured to be freely rotatable in the circumferential direction by the stepping motor.

    The first and second arms (51, 52) are formed in an elongated plate-like member and are attached to the rotating shaft (39). A first support (51a) is formed at the tip of the first arm (51) to contact the first movable plate (41a), and a second movable plate (41b) is formed at the tip of the second arm (52). The 2nd support part (52a) made to contact is formed. The first arm (51) has a proximal end attached to the rotation shaft (39) and a distal end extending toward the first movable plate (41a). The second arm (52) has a proximal end attached to the rotation shaft (39) and a distal end extending toward the second movable plate (41b).
