JP4360228B2 - Humidity adjuster and air supply / exhaust device - Google Patents

Description

  The present invention relates to a humidity adjusting body and an air supply / exhaust device, and can be applied to, for example, an air conditioner.

  A conventional air supply / exhaust device is provided with a rotor-type moisture absorbent having a dehumidifying side and a regeneration side, for example, a desiccant rotor. On the dehumidifying side, for example, air sent from outside is dehumidified and sent into the room. On the regeneration side, air heated by a heater or the like is sent to dry the moisture absorbent.

  In such an air supply / exhaust device, adsorption heat is generated when dehumidification is performed on the dehumidification side, so that the dehumidified air is warmed. Therefore, when the room is cooled, it is necessary to cool the dehumidified air by using a cooling device or the like. The heater used on the regeneration side is provided separately from the hygroscopic agent. For this reason, the size and complexity of the air supply / exhaust device have been increased.

  Therefore, recently, a technique using a Peltier module has been developed. That is, the adsorption heat generated on the dehumidifying side is absorbed by the Peltier module, and the absorbed heat is moved to the regeneration side to be used for regeneration of the moisture absorbent. This technique is disclosed in, for example, Patent Document 1 and Patent Document 2.

First embodiment.
FIG. 1 shows (a) configuration and (b) operation of a humidity adjusting body 101 provided in an air supply / exhaust device 7A (FIGS. 2 and 3) described later. The humidity adjusting body 101 includes the heat sinks 2 and 3 and the Peltier module 1 and is rotatable around an axis (rotation axis) along the direction X.

  The heat sink 2 has a plurality of flat fins 21 on which a hygroscopic agent is supported. Each of the fins 21 is parallel to both the direction X and the direction Y orthogonal to the direction X. The gas flowing in the heat sink 2 is guided in the direction Y. On the other hand, the heat sink 2 prevents gas movement in the direction Z perpendicular to both the directions X and Y.

  However, directions Y and Z are directions defined in humidity adjusting body 101 when direction X is fixed. Since the humidity adjusting body 101 is rotatable around an axis along the direction X, the directions Y and Z are orthogonal to the direction X in the motion coordinate system of the humidity adjusting body 101.

  The heat sink 3 has a plurality of flat fins 31 on which a hygroscopic agent is supported. Each of the fins 31 is parallel to both the direction X and the direction Z. The gas flowing in the heat sink 3 is guided in the direction Z. On the other hand, the heat sink 3 prevents gas movement in the direction Y.

  The Peltier module 1 is sandwiched between the heat sinks 2 and 3 in the direction X. The surfaces 1a and 1b of the Peltier module 1 are orthogonal to the direction X. A heat sink 2 is provided in contact with the surface 1a, and a heat sink 3 is provided in contact with the other surface 1b.

  One of the surfaces 1a and 1b of the Peltier module 1 functions as a heat absorbing surface and the other functions as a heat generating surface. Moreover, the heat absorption surface and the heat generation surface can be switched to each other by switching the direction of the direct current flowing through the Peltier module 1.

  In the above description, the X direction is the first direction, the Y direction is the second direction, the Z direction is the third direction, each of the heat sinks 2, 3 is the first, the second heat sink, and each of the surfaces 1a, 1b is the first, The 2nd surface and the Peltier module 1 can be grasped | ascertained with each thermoelectric element. If grasped in this way, the humidity adjusting body 101 can grasp as follows. That is, the humidity adjusting body 101 includes the first heat sink 2, the second heat sink 3, and the thermoelectric element 1. The first heat sink 2 guides the gas in the second direction Y orthogonal to the first direction X in the humidity adjustment body 101, and the first heat sink 2 is orthogonal to both the first direction X and the second direction Y in the humidity adjustment body 101. Prevents gas movement in the three directions Z. The second heat sink 3 guides the gas in the third direction Z and prevents the movement of the gas in the second direction Y in the humidity adjusting body 101. Both the first heat sink 2 and the second heat sink 3 carry a hygroscopic agent.

  The thermoelectric element 1 is sandwiched between the first heat sink 2 and the second heat sink 3 in the first direction X. And it has the 1st surface 1a which contacts the 1st heat sink 2, and the 2nd surface 1b which contacts the 2nd heat sink 3. FIG. The thermoelectric element 1 functions so that one of the first surface 1a and the second surface 1b can be switched to each other with the endothermic surface as the endothermic surface and the other as the heat generation surface.

  According to the humidity adjusting body 101 described above, when the first surface 1a of the thermoelectric element 1 functions as an endothermic surface, the heat of adsorption by the hygroscopic agent carried on the first heat sink 2 (more specifically, the fin 21). Is absorbed by the thermoelectric element 1. Therefore, the dehumidified gas can be discharged without warming the temperature of the gas. At this time, since the second surface 1b functions as a heat generating surface, it is possible to regenerate the moisture absorbent carried on the second heat sink 3 (more specifically, the fins 31). Alternatively, humidification can be performed with moisture released from the hygroscopic agent carried on the second heat sink 3.

  In addition, since the humidity adjusting body 101 is rotatable around the first direction X, by rotating the humidity adjusting body 101, the gas supplied from a predetermined direction is changed to the second direction Y and the third in the humidity adjusting body 101. The direction can be switched to Z. Therefore, when the direction in which the gas is guided is switched, it is regenerated by switching between one of the first surface 1a and the second surface 1b of the thermoelectric element 1 as the heat absorbing surface and the other as the heat generating surface. Moisture absorption by the hygroscopic agent can be performed efficiently. Or the humidification by the hygroscopic agent at the time of reproduction | regeneration can be performed efficiently. About this effect, it becomes clear in the air supply / exhaust device 7A mentioned later.

  2 and 3 conceptually show the air supply / exhaust device 7A according to the present embodiment. The air supply / exhaust device 7A includes a humidity adjusting body 101, intake ports 701a and 702a, exhaust ports 701b and 702b, isolation walls 71, fans 81 and 82, a commutation circuit 8, and a DC power source 9.

  The intake port 701a and the exhaust port 702b are provided outdoors, and the intake port 702a and the exhaust port 701b are provided indoors. For example, the fans 81 and 82 are used to suck and discharge the gas. In FIG. 2 (also in FIG. 3), the fan 81 is provided in the exhaust port 702b, and the fan 82 is provided in the exhaust port 701b.

  In FIG. 2, the direction X is perpendicular to the paper and toward the front. The fins 21 are along the direction from the intake port 702a toward the exhaust port 702b. The fins 31 are along the direction from the intake port 701a toward the exhaust port 701b.

  The isolation wall 71, together with the humidity adjusting body 101, isolates the intake port 701a and the exhaust port 701b from the intake port 702a and the exhaust port 702b. More specifically, the intake port 701a and the exhaust port 701b communicate with each other via the second heat sink 3 while being separated by the isolation wall 71 and the first heat sink 2. The intake port 702a and the exhaust port 702b communicate with each other via the first heat sink 2 while being separated by the isolation wall 71 and the second heat sink 3.

  The indoor gas sucked from the intake port 702a passes through the heat sink 2 and is discharged from the exhaust port 702b to the outside. This gas flow from the room to the room is indicated by an arrow EA. Further, the outdoor gas sucked from the intake port 701a passes through the heat sink 3 and is discharged from the exhaust port 701b to the room. The flow of gas from the outside to the inside of the room is indicated by an arrow SA.

  A DC power source 9 is connected to the Peltier module 1 via a commutation circuit 8. In FIG. 2, in the commutation circuit 8, the pair of switches S are in contact with, for example, the terminal 8 </ b> A side so that the heat sink 2 side surface 1 a is a heat generating surface and the heat sink 3 side surface 1 b is a heat absorbing surface.

  Therefore, the gas sucked from the air inlet 702a dries the hygroscopic agent on the heat sink 2 side (heat generating surface side). Further, the gas sucked from the air inlet 701a is dehumidified by the moisture absorbent on the heat sink 3 side (heat absorbing surface side). Since the heat generated during the moisture absorption is absorbed by the surface 1b, an increase in the room temperature due to dehumidification can be suppressed.

  If the humidity adjusting body 101 is maintained in the state shown in FIG. 2, the moisture absorbed by the moisture absorbent on the heat generating surface side (supported on the fins 21) will almost evaporate. In addition, in the hygroscopic agent on the heat absorption side (supported on the fins 31), the absorbed liquid is saturated. Therefore, the function of dehumidification / regeneration (humidification) of the humidity adjusting body 101 is lowered.

  Therefore, the humidity adjusting body 101 is rotated 90 degrees around the direction X (FIG. 3). In FIG. 3, the rotation of the humidity adjusting body 101 is also shown by rotating the directions Y and Z by 90 degrees. In FIG. 3, the fins 21 are along the direction from the intake port 701a to the exhaust port 701b. The fins 31 are along the direction from the intake port 702a toward the exhaust port 702b.

  The intake port 702a and the exhaust port 702b communicate with each other via the second heat sink 3 while being separated by the isolation wall 71 and the first heat sink 2. The intake port 701a and the exhaust port 701b communicate with each other via the first heat sink 2 while being separated by the isolation wall 71 and the second heat sink 3.

  Accordingly, the outdoor gas sucked from the intake port 701a passes through the heat sink 2 and is discharged from the exhaust port 701b to the room (arrow SA). Further, the indoor gas sucked from the air inlet 702a passes through the heat sink 3 and is discharged from the air outlet 702b to the outside (arrow EA).

  At this time, in the commutation circuit 8, the pair of switches S are switched so as to contact the terminal 8B. That is, in the Peltier module 1, the surface 1a on the heat sink 2 side is a heat absorbing surface, and the surface 1b on the heat sink 3 side is a heat generating surface.

  Therefore, the gas sucked from the air inlet 702a dries the hygroscopic agent on the heat sink 3 side (heat generating surface side). Further, the gas sucked from the air inlet 701a is dehumidified by the moisture absorbent on the heat sink 2 side (heat absorbing surface side). Since the heat of adsorption generated during the moisture absorption is absorbed by the surface 1a, an increase in the room temperature due to dehumidification can be suppressed. In other words, it is suitable for dehumidification during indoor cooling.

  Repeatedly, the humidity adjusting body 101 is rotated 90 degrees around the direction X, and each time the switch S is switched in the commutation circuit 8, the states shown in FIGS. Switch. With this operation, the air supply / exhaust device 7A can be dehumidified and the function can be maintained for a long time.

  In the above operation, by reversing the heat absorption / heat generation function of the surfaces 1a and 1b, the air supply / exhaust device 7A can be humidified and the function can be maintained for a long time. In this case, the gas sucked from the air inlet 701a is humidified by the moisture absorbent on the heat generating surface side. The heat given from the Peltier module 1 to the humidifying agent on the humidifying side can suppress a decrease in room temperature due to desorption heat during humidification. In other words, it is suitable for humidification during indoor heating. Further, the gas sucked from the air inlet 702a gives humidity to the hygroscopic agent on the heat absorbing surface side.

  In the above description, each of the intake ports 701a and 702a can be grasped as the first and second exhaust ports, and each of the exhaust ports 701b and 702b can be grasped as the first and second exhaust ports. In this case, the air supply / exhaust device 7A can be grasped as follows. That is, the air supply / exhaust device 7A includes the humidity adjusting body 101, the first air inlet 701a, the second air inlet 702a, the first air outlet 701b, the second air outlet 702b, and the isolation wall 71. The first intake port 701 a and the first exhaust port 701 b communicate with each other via one of the first heat sink 2 and the second heat sink 3. The second intake port 702 a and the second exhaust port 702 b communicate with each other via the other of the first heat sink 2 and the second heat sink 3. The isolation wall 71, together with the humidity adjusting body 101, isolates the first intake port 701a and the first exhaust port 701b from the second intake port 702a and the second exhaust port 702b.

  According to the air supply / exhaust device 7A described above, the dehumidification or humidification is performed on the gas flowing between the first intake port 701a and the first exhaust port 701b, while the second intake port 702a and the second exhaust port 702b are connected. Humidity can be discharged or absorbed with respect to the gas flowing between them. By rotating the humidity adjusting body 101 around the direction X, regeneration of the moisture absorbent and moisture absorption can be easily performed in parallel with a simple configuration.

  Further, the temperature and humidity of the gas can be adjusted by controlling the rotation timing of the humidity adjusting body 101. This content can be confirmed by a simulation result described below.

4 and 5 show the relationship between the power consumption in the Peltier module 1 and the amount of heat absorbed on the heat absorbing surface, obtained by simulation. The conditions of the simulation are that the size of the humidity adjusting body 101 is W90 mm × D90 mm × H84 mm, the temperature and humidity of the gas are 27 ° C. and 60% RH on the indoor side, and 35 ° C. and 50% RH on the outdoor side, respectively. Is 0.3 m ³ / min, showing a case where a steady state is reached.

  FIG. 4 shows the results when the humidity adjusting body 101 is rotated 90 degrees every 120 seconds. The sensible heat is represented by a curve 301 and the latent heat is represented by a curve 302. FIG. 5 shows the result when the rotation of the humidity adjusting body 101 is stopped. The sensible heat is represented by a curve 303 and the latent heat is represented by a curve 304.

  For example, when the power consumption in the Peltier module 1 is 40 W, the latent heat amount is 32 W and the sensible heat amount is 2 W in FIG. 4, and the latent heat amount is 0 W and the sensible heat amount is 25 W in FIG. When the humidity adjusting body 101 is rotated (FIG. 4), most of the power consumption is used for absorbing latent heat and hardly used for absorbing sensible heat. That is, the gas is dehumidified without increasing or decreasing the temperature of the gas.

  On the other hand, when the rotation of the humidity adjusting body 101 is stopped (FIG. 5), most of the power consumption is used for absorbing sensible heat and hardly used for absorbing latent heat. That is, the temperature of the gas is lowered with almost no dehumidification of the gas.

  Therefore, the humidity and temperature of the gas can be adjusted by adjusting the cycle of rotating the humidity adjusting body 101.

  In FIG. 2, the intake port 701a and the exhaust port 702b are provided outside the room, and the intake port 702a and the exhaust port 701b are provided inside the room, but they may be provided in other combinations. 6 to 9 show an air supply / exhaust device that performs the same operation as the air supply / exhaust device 7A shown in FIG. 2, and the arrangement of the intake ports 701a, 702a and the exhaust ports 701b, 702b is different from that of the air supply / exhaust device 7A.

  6 and 7, the intake ports 701a and 702a and the exhaust port 701b are installed indoors, and the exhaust port 702b is installed outdoors. Therefore, indoor air (gas) is circulated. In the air supply / exhaust device shown in FIG. 6, intake ports 701a and 702a are opened in different directions. In the air supply / exhaust device shown in FIG. 7, intake ports 701 a and 702 a are opened in the same direction, and both constitute an intake port 707.

  8 and 9, the intake port 701a and the exhaust port 701b are installed indoors, and the intake port 702a and the exhaust port 702b are installed outdoors. Therefore, the indoor air (gas) can be circulated independently of the outdoor air without introducing the outdoor air (gas) into the room.

  In the air supply / exhaust device shown in FIG. 9, an intake port 702c having a ventilation damper 130 on the indoor side and an intake port 701c having a ventilation damper 131 on the outdoor side are further installed. The air (gas) sucked from the intake port 702c is discharged to the exhaust port 702b together with the air (gas) sucked from the intake port 702a (arrow EA). The air (gas) sucked from the intake port 701c is discharged to the exhaust port 701b together with the air (gas) sucked from the intake port 701a (arrow SA). This air supply / exhaust device also performs ventilation in parallel with circulating indoor air (gas) and outdoor air (gas).

  The intake port 701c can be understood as the first intake port or the second intake port, together with the intake port 701a, and the intake port 701c, together with the intake port 702a.

Second embodiment.
FIG. 10 shows (a) configuration and (b) operation of the humidity adjusting body 102 provided in the air supply / exhaust device 7B (FIGS. 11 and 12) described later. The humidity adjusting body 102 includes the heat sinks 4 and 5 and the Peltier module 1 and is rotatable around an axis (rotation axis) along the direction X.

  The heat sink 4 has a plurality of flat fins 41 carrying a hygroscopic agent. Each of the fins 41 is orthogonal to the direction X and is parallel to the direction Y2 orthogonal to the direction X in the humidity adjusting body 102. And the gas which flowed to the heat sink 4 is guide | induced to the direction Y2.

  The heat sink 5 has a plurality of flat fins 51 on which a hygroscopic agent is supported. Each of the fins 51 is orthogonal to the direction X and is parallel to the direction Y1 opposite to the direction Y in the humidity adjusting body 102. And the gas which flowed to the heat sink 5 is guide | induced to the direction Y1.

  However, the directions Y1 and Y2 are directions defined in the humidity adjusting body 102 when the direction X is fixed. Since the humidity adjusting body 102 is rotatable around an axis along the direction X, the directions Y1 and Y2 are orthogonal to the direction X in the motion coordinate system of the humidity adjusting body 102.

  A heat sink 4 is provided in contact with one surface 1a of the Peltier module 1, and a heat sink 5 is provided in contact with the other surface 1b. The surfaces 1a and 1b are parallel to the directions X, Y1 and Y2. One of the surfaces 1a and 1b of the Peltier module 1 functions as a heat absorbing surface and the other functions as a heat generating surface. Moreover, the heat absorption surface and the heat generation surface can be switched to each other by switching the direction of the direct current flowing through the Peltier module 1.

  In the above description, the X direction is the first direction, the direction Y2 is the second direction, the direction Y1 is the third direction, each of the heat sinks 4 and 5 is the first, the second heat sink, and each of the surfaces 1a and 1b is the first, The 2nd surface and the Peltier module 1 can be grasped | ascertained with each thermoelectric element. In this case, the humidity adjusting body 102 can grasp as follows. That is, the humidity adjusting body 102 includes the first heat sink 4, the second heat sink 5, and the thermoelectric element 1. The first heat sink 4 enables the movement of gas in the second direction Y <b> 2 orthogonal to the first direction X in the humidity adjusting body 102. The second heat sink 5 enables gas movement in the humidity adjusting body 102 in the third direction Y1 opposite to the second direction Y2. A hygroscopic agent is carried on the first heat sink 4 and the second heat sink 5.

  The thermoelectric element 1 has a first surface 1 a that contacts the first heat sink 4 and a second surface 1 b that contacts the second heat sink 5. The thermoelectric element 1 functions so that one of the first surface 1a and the second surface 1b can be switched to each other with the endothermic surface as the endothermic surface and the other as the heat generation surface. Both the first surface 1a and the second surface 1b are parallel to the first direction X and the second direction Y2.

  According to the humidity adjusting body 102 described above, the same effect as the humidity adjusting body 101 described in the first embodiment can be obtained.

  11 and 12 conceptually show the air supply / exhaust device 7B according to the present embodiment. The air supply / exhaust device 7B includes a humidity adjusting body 102, intake ports 703a and 704a, exhaust ports 703b and 704b, isolation walls 72, fans 81 and 82, a commutation circuit 8, and a DC power source 9.

  The intake port 703a and the exhaust port 704b are provided outdoors, and the intake port 704a and the exhaust port 703b are provided indoors. For example, the fans 81 and 82 are used to suck and discharge the gas. In FIG. 11 (also in FIG. 12), the fan 81 is provided at the exhaust port 704b, and the fan 82 is provided at the exhaust port 703b.

  In FIG. 11, the direction X is perpendicular to the page and toward the front. The fins 41 are along the direction from the intake port 703a toward the exhaust port 703b. The fins 51 are along the direction from the intake port 704a to the exhaust port 704b.

  The isolation wall 72, together with the humidity adjusting body 102, isolates the intake port 703a and the exhaust port 703b from the intake port 704a and the exhaust port 704b. More specifically, the intake port 703a and the exhaust port 703b communicate with each other via the first heat sink 4 while being separated by the isolation wall 72 and the Peltier module 1. The intake port 704a and the exhaust port 704b communicate with each other via the second heat sink 5 while being separated by the isolation wall 72 and the Heltier module 1.

  The outdoor gas sucked from the air inlet 703a passes through the heat sink 4 and is discharged from the air outlet 703b into the room. The flow of gas from the outside to the inside of the room is indicated by an arrow SA. Further, the indoor gas sucked from the intake port 704a passes through the heat sink 5 and is discharged from the exhaust port 704b to the outside. This gas flow from the room to the room is indicated by an arrow EA.

  A DC power source 9 is connected to the Peltier module 1 via a commutation circuit 8. In FIG. 11, in the commutation circuit 8, the pair of switches S are in contact with, for example, the terminal 8B side so that the surface 1a on the heat sink 4 side is the heat absorbing surface and the surface 1b on the heat sink 5 side is the heat generating surface.

  Therefore, the gas sucked from the air inlet 704a dries the hygroscopic agent on the heat sink 5 side (heat generating surface side). Further, the gas sucked from the air inlet 703a is dehumidified by the moisture absorbent on the heat sink 4 side (heat absorbing surface side). Since the heat generated at the time of moisture absorption is absorbed by the surface 1a, an increase in the room temperature due to dehumidification can be suppressed.

  If the humidity adjusting body 102 is maintained in the state shown in FIG. 11, the function of dehumidification / regeneration (humidification) of the humidity adjusting body 102 is lowered for the same reason as in the first embodiment.

  Therefore, the humidity adjusting body 102 is rotated 180 degrees around the direction X (FIG. 12). In FIG. 12, the rotation of the humidity adjusting body 102 is also shown by rotating the directions Y1 and Y2 by 180 degrees. In FIG. 12, the fins 41 are along the direction from the intake port 704a toward the exhaust port 704b. The fins 51 are along the direction from the intake port 703a toward the exhaust port 703b.

  Therefore, the indoor gas sucked from the intake port 704a passes through the heat sink 4 and is discharged from the exhaust port 704b to the outdoor side. Further, the outdoor gas sucked from the intake port 703a passes through the heat sink 5 side and is discharged from the exhaust port 703b to the indoor side.

  At this time, in the commutation circuit 8, the pair of switches S are switched so as to contact the terminal 8A. That is, in the Peltier module 1, the surface 1a on the heat sink 4 side is a heat generating surface, and the surface 1b on the heat sink 5 side is a heat absorbing surface.

  Therefore, the gas sucked from the air inlet 704a dries the hygroscopic agent on the heat sink 4 side (heat generating surface side). Further, the gas sucked from the air inlet 703a is dehumidified by the hygroscopic agent on the heat sink 5 side (heat absorbing surface side). Since the heat of adsorption generated during the moisture absorption is absorbed by the surface 1b, an increase in the room temperature due to dehumidification can be suppressed. In other words, it is suitable for dehumidification during indoor cooling.

  Repeatedly, the humidity adjusting body 102 is rotated 180 degrees around the direction X, and each time the switch S is switched in the commutation circuit 8, the states shown in FIGS. Switch. With this operation, the air supply / exhaust device 7B can be dehumidified and the function can be maintained for a long time.

  In the above operation, by reversing the heat absorption / heat generation function of the surfaces 1a and 1b, the air supply / exhaust device 7B can be humidified and the function can be maintained for a long time. In this case, the gas sucked from the air inlet 703a is humidified by the moisture absorbent on the heat generating surface side. The heat given from the Peltier module 1 to the humidifying agent on the humidifying side can suppress a decrease in room temperature due to desorption heat during humidification. In other words, it is suitable for humidification during indoor heating. Further, the gas sucked from the air inlet 704a gives humidity to the hygroscopic agent on the heat absorbing surface side.

  In the above description, each of the intake ports 703a and 704a can be grasped as the first and second intake ports, and each of the exhaust ports 703b and 704b can be grasped as the first and second exhaust ports. In this case, the air supply / exhaust device 7B can be grasped as follows. That is, the air supply / exhaust device 7B includes the humidity adjusting body 102, the first air inlet 703a, the second air inlet 704a, the first air outlet 703b, the second air outlet 704b, and the isolation wall 72. The first intake port 703 a and the first exhaust port 703 b communicate with each other along one of the first heat sink 4 and the second heat sink 5. The second intake port 704 a and the second exhaust port 704 b communicate with each other along the other of the first heat sink 4 and the second heat sink 5. The isolation wall 72, together with the humidity adjusting body 102, isolates the first intake port 703a and the first exhaust port 703b from the second intake port 704a and the second exhaust port 704b.

  According to the air supply / exhaust device 7B described above, the dehumidification or humidification is performed on the gas flowing between the first intake port 703a and the first exhaust port 703b, while the second intake port 704a and the second exhaust port 704b are connected. Humidity can be discharged or absorbed with respect to the gas flowing between them. By rotating the humidity adjusting body 102 around the direction X, regeneration of the moisture absorbent and moisture absorption can be easily performed in parallel with a simple configuration.

  For the same reason as in the first embodiment, the temperature and humidity of the gas can be adjusted by controlling the rotation timing of the humidity adjusting body 102.

  In FIG. 11, the intake port 703a and the exhaust port 704b are provided outside the room, and the intake port 704a and the exhaust port 703b are provided inside the room, but they may be provided in other combinations. 13 to 16 show an air supply / exhaust device that performs the same operation as the air supply / exhaust device 7B shown in FIG. 11, and the arrangement of the intake ports 703a, 704a and the exhaust ports 703b, 704b is different from that of the air supply / exhaust device 7B.

  In the air supply / exhaust device shown in FIGS. 13 and 14, the intake ports 703a and 704a and the exhaust port 703b are set indoors, and the exhaust port 704b is set outdoor. Therefore, indoor air (gas) is circulated. In the air supply / exhaust device shown in FIG. 13, intake ports 703a and 704a are opened in different directions. In the air supply / exhaust device shown in FIG. 14, intake ports 703 a and 704 a are opened in the same direction, and both constitute an intake port 708.

  15 and 16, the intake port 703a and the exhaust port 703b are installed indoors, and the intake port 704a and the exhaust port 704b are installed outdoors. Therefore, the indoor air (gas) can be circulated independently of the outdoor air without introducing the outdoor air (gas) into the room.

  In the air supply / exhaust device shown in FIG. 16, a ventilation port 707 having a ventilation damper 132 is provided in the isolation wall 72 that separates the intake port 703a and the exhaust port 704b. In the ventilation port 707, air (gas) flows only in the direction from the intake port 703a to the exhaust port 704b. Further, a ventilation port 708 having a ventilation damper 133 is provided on the isolation wall 72 that separates the intake port 704a and the exhaust port 703b. In the ventilation port 708, air (gas) flows only in the direction from the intake port 704a to the exhaust port 703b. This air supply / exhaust device also performs ventilation in parallel with circulating indoor air (gas) and outdoor air (gas).

  That is, the ventilation damper 133, together with the isolation wall 72 and the humidity adjusting body 102, prevents gas movement from the first intake port 703 a and the first exhaust port 703 b to the second intake port 704 a. The ventilation damper 132, together with the isolation wall 72 and the humidity adjusting body 102, prevents gas movement from the second intake port 704a and the second exhaust port 704b to the first intake port 703a.

Third embodiment.
17 and 18 conceptually show an air supply / exhaust device 7C according to the present embodiment, and the state of the rotary damper 6 is different in each drawing. The air supply / exhaust device 7 </ b> C includes a rotary damper 6, a humidity adjusting body 103, intake ports 705 a and 706 a, exhaust ports 705 b and 706 b, an isolation wall 73, fans 81 and 82, a commutation circuit 8, and a DC power source 9.

  FIG. 19 conceptually shows (a) the rotary damper 6 and (b) the humidity adjusting body 103. The rotary damper 6 includes shielding plates 61a, 61b, 62a, 62b and a ring-shaped shielding plate 60, and is rotatable around an axis (rotation axis) along the direction X. The shielding plates 61 a and 61 b make a pair and guide the gas in the direction Y orthogonal to the direction X. The shielding plates 62 a and 62 b make a pair (hereinafter referred to as “shielding plate pair”) and guide the gas in the direction X and the direction Z orthogonal to the direction Y. The shielding plate pair 61a, 61b and the shielding plate pair 62a, 62b are connected via a ring-shaped shielding plate 60 and are aligned in the direction of the rotation axis (direction X).

  However, the directions Y and Z are directions defined in the humidity adjusting body 103 when the direction X is fixed. Since the humidity adjusting body 103 is rotatable around an axis along the direction X, the directions Y and Z are orthogonal to the direction X in the motion coordinate system of the humidity adjusting body 103.

  In the above description, the rotary damper 6 is a shield, the direction X is the first direction, the direction Y is the second direction, the direction Z is the third direction, the shield plate pairs 61a and 61b are the first shield plate pair, and the shield plate. The pairs 62a and 62b can be grasped as the second shielding plate pair. When grasped in this way, the shield 6 can be grasped as follows. That is, the shield 6 is rotatable around an axis along the first direction X, and includes the first shield plate pair 61a and 61b and the second shield plate pair 62a and 62b. The first shielding plate pair 61a, 61b guides the gas in the shielding body 6 in the second direction Y orthogonal to the first direction X. The second shielding plate pair 62a, 62b guides the gas in the shielding body 6 in the third direction orthogonal to both the first direction X and the second direction Y. The first shielding plate pair 61a, 61b and the second shielding plate pair 62a, 62b are arranged in the first direction X.

  The humidity adjusting body 103 includes heat sinks 20 and 30 and a Peltier module 1. The heat sink 20 has a plurality of columnar fins 22 carrying a hygroscopic agent. The fin 22 extends in the direction X. The heat sink 30 has a plurality of columnar fins 32 carrying a hygroscopic agent. The fins 32 extend in the direction X.

  The Peltier module 1 is sandwiched between the heat sinks 20 and 30 in the direction X. The surfaces 1a and 1b of the Peltier module 1 are orthogonal to the direction X. A heat sink 20 is provided in contact with the surface 1a, and a heat sink 30 is provided in contact with the other surface 1b.

  One of the surfaces 1a and 1b of the Peltier module 1 functions as a heat absorbing surface and the other functions as a heat generating surface. Moreover, the heat absorption surface and the heat generation surface can be switched to each other by switching the direction of the direct current flowing through the Peltier module 1.

  In the above description, each of the heat sinks 20 and 30 is a first and second heat sink, each of the fins 22 and 32 is a first and second pillar, each of the surfaces 1a and 1b is a first and second surface, and a Peltier module. 1 can be grasped as a thermoelectric element. If grasped in this way, the humidity adjusting body 103 can be grasped as follows. That is, the humidity adjusting body 103 includes the first heat sink 20, the second heat sink 30, and the thermoelectric element 1, and is surrounded by the shield 6. The first heat sink 20 has a plurality of first pillars 22 extending in the first direction X and carrying a hygroscopic agent. The second heat sink 30 has a plurality of second pillars 32 extending in the first direction X and carrying a hygroscopic agent.

  The thermoelectric element 1 is sandwiched between the first heat sink 20 and the second heat sink 30 in the first direction X. And it has the 1st surface 1a which contacts the 1st heat sink 20, and the 2nd surface 1b which contacts the 2nd heat sink 30. As shown in FIG. The thermoelectric element 1 functions so that one of the first surface 1a and the second surface 1b can be switched to each other with the endothermic surface as the endothermic surface and the other as the heat generation surface.

  In FIG. 17 and FIG. 18, the direction X is perpendicular to the paper and toward the front. The rotary damper 6 is provided so as to be rotatable around the humidity adjusting body 103. The gas guided in the direction Y by the pair of shielding plates 61a and 61b passes through the heat sink 20 side. The gas guided in the direction Z by the shielding plate pairs 62a and 62b passes through the heat sink 30 side.

  In FIG. 17, the isolation wall 73, the pair of shielding plates 61a and 61b, and the pair of shielding plates 62a and 62b, together with the humidity adjusting body 103, isolate the intake port 705a and the exhaust port 705b from the intake port 706a and the exhaust port 706b. . More specifically, the intake port 705a and the exhaust port 705b communicate with each other through the opening between the pair of shielding plates 62a and 62b while being separated by the pair of shielding plates 61a and 61b and the isolation wall 73. Similarly, the intake port 706a and the exhaust port 706b communicate with each other through an opening between the pair of shielding plates 61a and 61b while being separated by the pair of shielding plates 62a and 62b and the separating wall 73.

  An intake port 705a and an exhaust port 706b are provided outdoors, and an intake port 706a and an exhaust port 705b are provided indoors. For example, the fans 81 and 82 are used to suck and discharge the gas. In FIG. 17 (also in FIG. 18), the fan 81 is provided at the exhaust port 706b and the fan 82 is provided at the exhaust port 705b.

  Therefore, the indoor gas sucked from the intake port 706a passes through the heat sink 20 and is discharged from the exhaust port 706b to the outdoor side. The flow of gas from the indoor side to the outdoor side is indicated by an arrow EA. Further, the outdoor gas sucked from the intake port 705a passes through the heat sink 30 side and is discharged from the exhaust port 705b to the indoor side. The flow of gas from the outdoor side to the indoor side is indicated by an arrow SA.

  A DC power source 9 is connected to the Peltier module 1 via a commutation circuit 8. In FIG. 17, in the commutation circuit 8, the pair of switches S are in contact with, for example, the terminal 8A side so that the surface 1a on the heat sink 20 side is a heat generating surface and the surface 1b on the heat sink 30 side is a heat absorbing surface.

  Therefore, the gas sucked from the air inlet 706a dries the moisture absorbent on the heat sink 20 side (heat generating surface side). Further, the gas sucked from the air inlet 705a is dehumidified by the moisture absorbent on the heat sink 30 side (heat absorbing surface side). Since the heat generated during the moisture absorption is absorbed by the surface 1b, an increase in the room temperature due to dehumidification can be suppressed.

  If the humidity adjusting body 103 is maintained in the state shown in FIG. 17, the function of dehumidification / regeneration (humidification) of the humidity adjusting body 103 is lowered for the same reason as in the first embodiment.

  Therefore, the rotary damper 6 is rotated 90 degrees around the direction X (FIG. 18). In FIG. 18, the rotation of the humidity adjusting body 103 is also shown by rotating the directions Y and Z by 90 degrees. In FIG. 18, the intake port 705a and the exhaust port 705b communicate with each other through the opening between the pair of shielding plates 61a and 61b while being separated by the pair of shielding plates 62a and 62b and the separating wall 73. Similarly, the intake port 706a and the exhaust port 706b communicate with each other through an opening between the pair of shielding plates 62a and 62b while being separated by the pair of shielding plates 61a and 61b and the separating wall 73.

  Therefore, the outdoor gas sucked from the intake port 705a passes through the heat sink 20 side and is discharged from the exhaust port 705b to the indoor side (arrow SA). Further, the indoor gas sucked from the intake port 706a passes through the heat sink 30 and is discharged from the exhaust port 706b to the outdoor side (arrow EA).

  At this time, in the commutation circuit 8, the pair of switches S are switched so as to contact the terminal 8B. That is, in the Peltier module 1, the surface 1a on the heat sink 20 side is a heat absorbing surface, and the surface 1b on the heat sink 30 side is a heat generating surface.

  Therefore, the gas sucked from the air inlet 706a dries the hygroscopic agent on the heat sink 30 side (heat generating surface side). Further, the gas sucked from the air inlet 705a is dehumidified by the moisture absorbent on the heat sink 20 side (heat resting surface side). Since the heat of adsorption generated during the moisture absorption is absorbed by the surface 1a, an increase in the room temperature due to dehumidification can be suppressed. In other words, it is suitable for dehumidification during indoor cooling.

  Repeatedly, the rotary damper 6 is rotated 90 degrees around the direction X, and each time the switch S is switched in the commutation circuit 8, the states shown in FIGS. Switch. With this operation, the air supply / exhaust device 7C can be dehumidified in the room and its function can be maintained for a long time.

  In the above operation, by reversing the heat absorption / heat generation function of the surfaces 1a and 1b, the air supply / exhaust device 7C can be humidified and the function can be maintained for a long time. In this case, the gas sucked from the air inlet 705a is humidified by the moisture absorbent on the heat generating surface side. The heat given from the Peltier module 1 to the humidifying agent on the humidifying side can suppress a decrease in room temperature due to desorption heat during humidification. In other words, it is suitable for humidification during indoor heating. Further, the gas sucked from the intake port 706a gives humidity to the hygroscopic agent on the heat absorbing surface side.

  In the above description, each of the intake ports 705a and 706a can be grasped as the first and second intake ports, and each of the exhaust ports 705b and 706b can be grasped as the first and second exhaust ports. In this case, the air supply / exhaust device 7C can be grasped as follows. That is, the air supply / exhaust device 7 </ b> C includes the shielding body 6, the humidity adjusting body 103, the first intake port 705 a, the second intake port 706 a, the first exhaust port 705 b, the second exhaust port 706 b, and the isolation wall 73. The first intake port 705a and the first exhaust port 705b communicate with each other via one of the first shielding plate pair 61a, 61b and the second shielding plate pair 62a, 62b. The second intake port 706a and the second exhaust port 706b communicate with each other via the other of the first shielding plate pair 61a, 61b and the second shielding plate pair 62a, 62b. The isolation wall 73, together with the humidity adjusting body 103, isolates the first intake port 705a and the first exhaust port 705b from the second intake port 706a and the second exhaust port 706b.

  According to the air supply / exhaust device 7 </ b> C described above, when the first surface 1 a of the thermoelectric element 1 functions as a heat absorption surface, the heat of adsorption by the hygroscopic agent supported on the first column 22 is absorbed by the thermoelectric element 1. Therefore, the dehumidified gas can be discharged without warming the temperature of the gas. At this time, since the second surface 1b functions as a heat generating surface, the hygroscopic agent supported on the second column 32 can be regenerated. Alternatively, humidification can be performed with moisture released from the hygroscopic agent supported on the second column 32.

  In addition, since the shield 6 is rotatable around the axis (direction X), by rotating the shield 6, the gas applied from a predetermined direction is changed to the second direction Y and the third in the humidity adjusting body 103. The direction can be switched to Z. Therefore, when the direction in which the gas is guided is switched, it is regenerated by switching between one of the first surface 1a and the second surface 1b of the thermoelectric element 1 as the heat absorbing surface and the other as the heat generating surface. Moisture absorption by the hygroscopic agent can be performed efficiently. Or the humidification by the hygroscopic agent at the time of reproduction | regeneration can be performed efficiently.

  Then, while dehumidifying or humidifying the gas flowing between the first intake port 705a and the first exhaust port 705b, the humidity flowing with respect to the gas flowing between the second intake port 706a and the second exhaust port 706b, respectively. Discharge or moisture absorption. By rotating the shielding body 6 surrounding the humidity adjusting body 103 around the axis (direction X), it is possible to easily perform the regeneration of the moisture absorbent and the moisture absorption in parallel with a simple configuration.

  Further, for the same reason as in the first embodiment, the temperature and humidity of the gas can be adjusted by controlling the timing of rotation of the shield 6.

  In any of the above-described embodiments, the air supply / exhaust devices 7A to 7C are considered to have equivalent dehumidification or humidification performance. Which air supply / exhaust device to use can be determined from the ease of production, cost, and the like.
