  The present invention relates to a magnetic heat storage material type temperature adjusting device provided with a magnetic heat storage material that increases in temperature when energized and decreases in temperature when demagnetized, and for a vehicle in which this is applied to a vehicle. It relates to an air conditioner.

Conventionally, as described in Patent Document 1, there is a magnetic heat storage material type temperature control device that can be used even at room temperature. This magnetic heat storage material type temperature control device includes a heat exchange circuit through which heat exchange fluid flows, a radiator from which heat of the heat exchange fluid is released, a cooler that is cooled by the endothermic action of the heat exchange fluid, and heat exchange fluid. A circulator that circulates in the exchange circuit, a magnetic regenerator that contains a magnetic regenerator material in a container, and a magnetic field generator that generates a magnetic field are provided. In this magnetic heat storage material type temperature control device, the magnetic heat storage material can take two states, a high temperature state in which the magnetic heat storage material is excited by a magnetic field and a low temperature state in which the magnetic heat storage material is demagnetized. In other words, in the radiator, the heat exchange fluid radiates heat to the heat radiating body, and in the cooler, the heat exchange fluid absorbs heat from the chilled body. More specifically, when the magnetic heat storage material is excited, the heat exchange fluid radiates heat to the heat exchange fluid, and the heat exchange fluid that has absorbed heat from the magnetic heat storage material flows to the radiator and radiates heat to the heated object. Then, the heat exchange fluid radiated to the heated body by the radiator flows toward the magnetic heat storage material that has been demagnetized and brought to a low temperature state. Next, the heat exchange fluid is absorbed by the magnetic heat storage material, then flows into the cooler, and absorbs heat from the object to be cooled.

  In the above prior art, heat is exchanged between the high-temperature or low-temperature magnetic heat storage material and the heat exchange fluid, and then the heat is radiated to the heated object by the radiator and the heat is absorbed from the cooled object by the cooler. As described above, indirect heat exchange is performed by interposing a heat exchange fluid between the magnetic heat storage material, the radiator and the cooler, so that the radiator, cooler, heat exchange circuit and heat exchange fluid are circulated. A circulator is required. Therefore, there has been a problem that the configuration of the magnetic heat storage material type temperature control device becomes complicated.

  In view of the above points, an object of the present invention is to provide a magnetic heat storage material type temperature control device that enables direct heat exchange between a magnetic heat storage material and air.

  In order to achieve the above object, according to the first aspect of the present invention, the ventilation path (9) for introducing air into the room, the heat exchange flow path (14) through which the heat exchange fluid flows, and the magnetocaloric effect when excited. The magnetic regenerator (10, 16, 50) having the magnetic regenerator material (13) that rises in temperature to become a high-temperature state and demagnetizes to a low-temperature state when demagnetized, and the ventilation path (9) or Magnetic heat generating means (27, 28, 37) for generating a magnetic field in the heat exchange flow path (14), the magnetic regenerator (10, 16, 50) includes the ventilation path (9) and the heat exchange flow path (14 When the magnetic heat accumulator (10, 16, 50) moves to the ventilation path (9), it is possible to select excitation or demagnetization of the magnetic field generating means (27, 28, 37). The magnetic heat storage material (13) is in one of a high temperature state and a low temperature state, When moving to the exchange flow path (14), the magnetic heat storage material (13) enters the other state of the high temperature state and the low temperature state by selecting excitation or demagnetization of the magnetic field generating means (27, 28, 37), and ventilation When the magnetic regenerator (13, 16 and 50) moves to the path (9), the heat is dissipated to the air when the magnetic regenerator (13) becomes a high temperature, and the heat is absorbed from the air when the magnetic regenerator (13) becomes a low temperature. It is designed to do this.

  According to this, since the magnetic regenerator (10, 16, 50) is movable to the ventilation path (9) and the heat exchange flow path (14), the air in the ventilation path (9) and the heat exchange flow path. Heat exchange with the heat exchange fluid of (14) is possible. Specifically, the magnetic heat storage material (13) enters a high temperature state where the magnetic heat storage material (10, 16, 50) is excited and increases in temperature with the movement of the magnetic heat storage device (10, 16, 50). ) Or the heat exchange fluid in the heat exchange flow path (14) is low, the heat is radiated to the air or the heat exchange fluid. The magnetic heat storage material (13) is in a low temperature state where the temperature is demagnetized to lower the temperature, and the temperature of the air in the ventilation path (9) or the heat exchange fluid in the heat exchange channel (14) is lower than the temperature in the low temperature state. When the temperature is high, it absorbs heat from air or heat exchange fluid. Thus, the magnetic heat storage material (13) becomes a high temperature state or a low temperature state due to the movement of the magnetic heat storage device (10, 16, 50), so that the air in the ventilation path (9) and the heat exchange flow path (14 Heat exchange fluid). By the way, since the magnetic field generation means (27, 28, 37) can generate a magnetic field in the ventilation path (9) or the heat exchange flow path (14), the magnetic heat storage material (13) in the ventilation path (9), Alternatively, the magnetic heat storage material (13) in the heat exchange channel (14) can be brought into a high temperature state or a low temperature state. Accordingly, the magnetic regenerator (10, 16, 50) can not only directly exchange heat with the air introduced into the room, but can also cool or heat the air into the room. In short, the magnetic regenerator (10, 16, 50) moves through the ventilation path (9) and the heat exchange flow path (14) to form a refrigerating cycle for heat storage and heat dissipation of the magnetic heat storage material (13). Can do.

  If the magnetic field generating means (27, 28, 37) is provided in the ventilation path (9) and the heat exchange path (14), respectively, as in the invention described in claim 2, the ventilation path is provided. Since the magnetic heat storage material (13) of the path (9) can be brought into a high temperature state or a low temperature state, air can be cooled or heated.

  Like invention of Claim 3, in Claim 1, the magnetic field generation | occurrence | production means (27, 28, 37) is provided so that a movement is possible, and a ventilation path (9) and a heat exchange flow path (14) are provided. If it moves to either one, a magnetic field can be generated in one of the ventilation path (9) and the heat exchange path (14).

  As in the invention described in claim 4, in any one of claims 1 to 3, the heat exchange fluid is air, and the magnetic regenerator (10, 16, 50) absorbs moisture in the air. If the hygroscopic material (12) to be integrated is provided integrally, moisture can be absorbed from the air, so that an increase in indoor humidity can be suppressed. Further, when the magnetic heat storage material (13) enters the magnetic field and the temperature rises, the hygroscopic material (12) can be warmed, so that the hygroscopic material (12) can also be regenerated. Further, when the magnetic heat storage material (13) is demagnetized and the temperature is lowered, it can be dehumidified by the hygroscopic material (12), so that not only the magnetic heat storage material (13) can be prevented from freezing, but also in a narrow room such as a passenger compartment. When used in a space, there is also an anti-fogging effect of the window glass.

  According to a fifth aspect of the present invention, in the fourth aspect, the first outside air introduction port (4) for introducing outside air into the ventilation path (9), and the inside air passage (5) for introducing inside air into the ventilation path (9), The first internal / external air switching door (6) is provided on the air flow upstream side of the ventilation path (9) and switches between outside air and inside air, and the first inside / outside air switching door (6) is switched to the outside air introduction side. The air flows from the first outside air inlet (4) toward the ventilation path (9).

  According to this, when there is a magnetic field in the heat exchange flow path (14), the magnetic heat accumulator (10, 16, 50) absorbs heat from the air in the ventilation path (9), and becomes the air in the heat exchange flow path (14). By dissipating heat, indoor air can be cooled. On the other hand, when there is a magnetic field in the ventilation path (9), the magnetic regenerator (10, 16, 50) radiates heat to the air in the ventilation path (9) and absorbs heat from the air in the heat exchange path (14). Can warm indoor air. Further, by introducing the outside air from the first outside air introduction port (4) in this way, it is possible to suppress an increase in the carbon dioxide concentration in the room and to discharge the room odor.

  In invention of Claim 6, in Claim 4 or 5, the 2nd which introduce | transduces external air into the 1st air blower (7) which ventilates external air or internal air to a ventilation path (9), and a heat exchange flow path (14).

And a second blower (17) for sending.

  According to this, the air of a ventilation path (9) can be sent indoors by a 1st air blower (7), and the air of a heat exchange flow path (14) can be discharge | released outdoors by a 2nd air blower (17). Therefore, in the ventilation path (9), when air radiated from the magnetic regenerator (10, 16, 50) is sent indoors, in the heat exchange flow path (14), the air is transferred to the magnetic regenerator (10, 16, 50) is absorbed and sent to the air outlet (14b). On the other hand, when the air absorbed from the magnetic regenerator (10, 16, 50) is sent indoors, the heat is radiated from the magnetic regenerator (10, 16, 50) in the heat exchange channel (14). To the air outlet (14b). Further, since the outside air can be introduced from the second outside air introduction port (29) into the heat exchange flow path (14) by the second inside / outside air switching door (15), the outside air from the second outside air introduction port (29). Can be passed through the heat exchange channel (14) to exchange heat with the magnetic heat storage material (13). Therefore, it is not necessary to exchange heat by sending air in the air-conditioned room to the heat exchange channel (14), and the temperature in the room can be adjusted efficiently. In this case, since the conditioned air circulates in the room, there is an effect that it is difficult for outdoor dust to enter the room.

  As in the invention described in claim 7, if the second blower (17) and the first blower (7) are arranged close to each other in claim 6, the first blower (7) is provided by one motor. And the second blower (17) can be driven. Moreover, the air volume of a 1st air blower (7) and a 2nd air blower (17) can also be match | combined by driving with one motor.

  In the invention of claim 8, in any one of claims 4 to 7, when the magnetic regenerator (10, 16, 50) moves to the ventilation path (9), the magnetic regenerator material (13) is in a low temperature state. When moving to the heat exchange flow path (14), the magnetic heat storage material (13) is in a high temperature state, and when the magnetic heat storage (10, 16, 50) moves to the ventilation path (9), the air flow upstream The hygroscopic material (12) is positioned on the side and the magnetic heat storage material (13) is positioned on the downstream side of the air flow. When the hygroscopic material (13) is moved to the heat exchange channel (14), the magnetic heat storage material is positioned on the upstream side of the air flow. (13) is located, and the moisture absorbent (12) is located downstream of the air flow.

  According to this, since the magnetic field generating means (27, 28, 37) generates a magnetic field in the heat exchange flow path (14), the magnetic regenerator (10, 16, 50) moves to the ventilation path (9). Then, heat is absorbed from the air. In such a case, when the magnetic regenerator (10, 16, 50) moves to the ventilation path (9), the air passing by the moisture absorbent (12) upstream of the air flow of the magnetic regenerator (10, 16, 50). Because it can absorb moisture, it can dehumidify indoor air. When the magnetic regenerator (10, 16, 50) moves to the heat exchange channel (14), the magnetic regenerator material (13) is positioned upstream of the air flow of the magnetic regenerator (10, 16, 50). Therefore, the magnetic heat storage material (13) radiates heat to the passing air, and the air heated by this heat radiation is sent to the moisture absorption material (12), so that the moisture absorption material (12) can be regenerated.

  In invention of Claim 9, in any one of Claim 4 thru | or 7, when a magnetic regenerator (10, 16, 50) moves to a ventilation path (9), a magnetic heat storage material (13) will be in a high temperature state.

In such a case, when the magnetic regenerator (10, 16, 50) moves to the ventilation path (9), heat is radiated from the magnetic regenerator (13) of the magnetic regenerator (10, 16, 50) to the passing air. Therefore, the water | moisture content of the moisture absorption material (12) in the downstream is sent indoors. Further, when the magnetic regenerator (10, 16, 50) moves to the heat exchange channel (14), the hygroscopic material (12) can absorb moisture from the air in the heat exchange channel (14). Therefore, a change in the humidity of the indoor air can be suppressed.

  As in the invention described in claim 10, in any one of claims 4 to 7, if the magnetic heat storage material (13) and the hygroscopic material (12) are arranged in the same container, the magnetic heat storage material ( Since heat is efficiently transmitted to the hygroscopic material (12) during the heat radiation of 13), the hygroscopic material (12) can be efficiently regenerated.

  As in the invention described in claim 11, in any one of claims 4 to 10, the magnetic regenerator (10, 16, 50) may be provided with a filter member (11) for removing dirt in the air. As a result, it is possible to prevent outdoor dirty air from entering the room.

  As in the invention described in claim 12, in claim 11, when the magnetic regenerator (10, 16, 50) moves to the ventilation path (9), the filter member (11) is positioned upstream of the air flow, The magnetic heat storage material (13) is positioned on the downstream side of the air flow. When the magnetic heat storage material (13) is moved to the heat exchange channel (14), the magnetic heat storage material (13) is positioned on the upstream side of the air flow, and the filter member ( 11) is located, in the ventilation path (9), dirt in the air is less likely to flow into the room, so that the inflow of dust into the room is suppressed and the magnetic heat storage material (13) and the hygroscopic material ( 12) can be protected. Moreover, in the heat exchange flow path (14), the dirt adhering to the filter member (11) can be discharged to the outside.

  As in the invention described in claim 13, in any one of claims 1 to 12, the magnetic regenerator (10, 16, 50) includes a first magnetic regenerator (10) and a second magnetic regenerator ( 16), when one side of the first magnetic regenerator (10) and the second magnetic regenerator (16) moves to the ventilation path (9), the other side moves to the heat exchange flow path (14). The magnetic heat storage material (13) changes alternately between a high temperature state and a low temperature state by the movement of the first magnetic heat storage device (10) and the second magnetic heat storage device (16). If so, not only can the temperature and humidity be adjusted continuously for the air passing through the ventilation path (9), but the use and regeneration of the hygroscopic material (12) can be alternated.

  When the magnetic heat storage material type temperature control device according to any one of claims 1 to 13 is applied to a vehicle as in the invention according to claim 14, a conventional phase change between the gas phase and the liquid phase is used. It may be possible to make the structure simpler than that of a vehicle air conditioner configured by equipment such as a heat exchanger for cooling and a heat exchanger for heating using waste heat of the engine.

In response to the inside / outside air switching signal from the control device, the first inside / outside air switching door 6 rotates to the position where the inside air ventilation path 5 is closed and the first outside air introduction port 4 is opened, that is, the outside air introduction position, or The inside air ventilation path 5 is opened and the first outside air introduction port 4 is closed, that is, the inside air circulation position is rotated. Further, the control device transmits a signal to the drive unit of the first inside / outside air switching door 6 and also transmits a signal to the drive unit of the second inside / outside air switching door 15. For example, when the first inside / outside air switching door 6 rotates and moves to the outside air introduction position, the second inside / outside air switching door 15 opens the passage between the second ventilation path 14 and the vehicle interior. Further, when the first inside / outside air switching door 6 moves to the inside air circulation position, the second inside / outside air switching door 15 moves to a position where the passage between the second ventilation path 14 and the vehicle interior is blocked.

  The first blower 7 is driven by the first blower motor 8 to blow air toward the vehicle interior. The first blower motor 8 is controlled based on a blower voltage signal from the control device. The blown air from the first blower 7 is sent to the first ventilation path 9 in the direction of the arrow X. The blown air passes through the first magnetic regenerator 10 or the second magnetic regenerator 16 and enters the vehicle interior. In addition, the blown air passes through the first ventilation path 9 in the order of the filter 11, the hygroscopic material 12, and the magnetic heat storage material 13. The filter 11 can remove dirt in the air. Further, the hygroscopic material 12 can dehumidify the air. The hygroscopic material 12 is, for example, silica gel or zeolite. Moreover, in the magnetic heat storage material 13, the temperature of air can be adjusted.

  The second blower 17 is driven by the second blower motor 18 to blow the air on the vehicle rear side of the second ventilation path 14 in the direction of the arrow Y on the vehicle front side. And the air which flows through this 2nd ventilation path 14 passes the 1st magnetic regenerator 10 or the 2nd magnetic regenerator 16, and is discharged | emitted out of a vehicle interior. In addition, the air before discharge passes through the second air passage 14 in the order of the magnetic heat storage material 13, the hygroscopic material 12, and the filter 11. When air passes through the magnetic heat storage material 13, heat can be absorbed from the air or can be radiated to the air. When radiating heat to the air, the hygroscopic material 12 on the downstream side of the air flow can be warmed, so that the hygroscopic material 12 can be efficiently regenerated. Further, since air flows from the direction opposite to the direction in which the dirt adheres to the filter 11, the dirt on the surface of the filter 11 can be removed.

  On the other hand, the control device transmits signals to the first and second blowers 7, 17, the first inside / outside air switching door 6, and the second inside / outside air switching door 15, and simultaneously transmits a control signal to the servo motor 24. When the servo motor 24 receives a signal from the control device, the servo motor 24 is moved in one direction until the first magnetic heat accumulator 10 and the second magnetic heat accumulator 16 reach predetermined positions of the first and second ventilation paths 9 and 14, respectively. It rotates to drive the drive side rotor 22. When the first magnetic regenerator 10 and the second magnetic regenerator 16 reach the predetermined positions of the first and second ventilation passages 9 and 14, the servo motor 24 rotates in the direction opposite to the one direction side to drive the rotor. 22 is reversely driven. By repeating this operation, the first magnetic regenerator 10 and the second magnetic regenerator 16 are alternately moved to the first and second ventilation paths 9 and 14, respectively.

  By the way, a current flows through one of the first electromagnet 27 in the first ventilation path 9 and the second electromagnet 28 in the second ventilation path 14. For example, when the temperature of the air in the passenger compartment is lower than the set temperature input to the temperature setting unit, the magnetic heat storage material 13 of the first magnetic regenerator 10 and the second magnetic regenerator 16 is energized by energizing the first electromagnet 27. Is heated by magnetizing the air to heat the air in the first ventilation path 9. At this time, the power source of the second electromagnet 28 is turned off. When the temperature of the air in the passenger compartment is higher than the set temperature input to the temperature setting unit, the second electromagnet 28 is energized to absorb heat from the air in the first ventilation path 9. At this time, the power source of the first electromagnet 27 is turned off.

Next, the function and effect of the first embodiment of the present invention will be described.
(1) By providing the first magnetic regenerator 10 and the second magnetic regenerator 16 with the hygroscopic material 12 together with the magnetic heat regenerator 13, the dehumidifying capacity can be enhanced. In cooling, the sensible heat after dehumidification is cooled, so that the cooling effect can be improved. Further, it is possible to regenerate by releasing the humidity from the hygroscopic material 12 by the heat of the magnetic heat storage material 13 in the second ventilation path 14. Moreover, at the time of heating, the fall of the humidity in a vehicle interior can be suppressed by raising the temperature of the hygroscopic material 12.
(2) By providing the filter 11 with the magnetic heat storage material 13 in the 1st magnetic heat storage device 10 and the 2nd magnetic heat storage device 16, the dust contained in the blowing air to a vehicle interior can be removed. Moreover, since the dust removed by the filter 11 is discharged out of the passenger compartment when the first magnetic regenerator 10 and the second magnetic regenerator 16 move to the second ventilation path 14, the air in the passenger compartment is continuously maintained. In addition to suppressing dirt on the filter 11, clogging of the filter 11 can also be suppressed. Further, it is possible to protect the magnetic heat storage material 13 and the hygroscopic material 12, and to suppress bad odor due to the dirt of the filter 11.
(3) When the first magnetic regenerator 10 and the second magnetic regenerator 16 alternately move up and down, continuous air conditioning can be executed.
