JP 2008-224074 A (paragraphs [0042] to [0047], FIG. 4)

  In the air conditioning apparatus as described above, the rotation speeds of the two moisture adsorbing means are set to be the same. In order to exhibit the maximum capacity in both moisture adsorption means, it is necessary to consider the number of rotations of each of the two moisture adsorption means, and there is room for improvement in this respect. In the air conditioner as described above, the temperature of the air adsorbed together with the moisture by the first moisture adsorbing means rises due to the heat of adsorption generated during the moisture adsorption, and the relative humidity is lowered. When the relative humidity of the air decreases, the amount of dehumidification by the adsorbent decreases. In order to sufficiently dehumidify by the second moisture adsorption means, it is necessary to consider the relative humidity of the air supplied from the first moisture adsorption means, and there is room for improvement in this respect as well.

It is constituted by a moisture adsorption means and a second moisture adsorption means, and the rotation of the first moisture adsorption means and the rotation of the second moisture adsorption means are performed individually.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
Embodiment 1 FIG.
FIG. 1 is a schematic configuration diagram schematically showing a configuration of an air-conditioning apparatus 100 according to Embodiment 1 of the present invention. Based on FIG. 1, the structure of the air conditioning apparatus 100 is demonstrated. The air conditioner 100 can perform a cooling operation or a heating operation using a refrigeration cycle in which a refrigerant is circulated. In addition, the air conditioner 100 can perform a dehumidifying operation. In addition, in the following drawings including FIG. 1, the relationship of the size of each component may be different from the actual one.

  As shown in FIG. 1, the air conditioner 100 includes a refrigeration cycle in which a compressor 1, a condenser 2, a throttling device 3, and a cooler 4 are connected in series, and two moisture adsorption means (first rotor 7, A second rotor 8). In the main body 50, two air paths (adsorption air path 20 and desorption air path 21) are formed by the adsorption / desorption air path partition 9. The condenser 2 is disposed on the windward side of the desorption air passage 21, the cooler 4 is disposed on the windward side of the adsorption air passage 20, and the first rotor 7 and the second rotor 8 are disposed across the two air passages. . The adsorption air passage 20 is provided with an adsorption-side air passage partition 10 that prevents the air that has passed through the cooler 4 from bypassing the two moisture adsorption means. Further, the desorption air passage 21 is provided with a desorption side air passage partition 11 that prevents the air that has passed through the condenser 2 from bypassing the two moisture adsorption means.

  The main body 50 is formed with a first intake port 20a for taking indoor air into the adsorption air passage 20 and a first air outlet 20b for supplying air flowing through the adsorption air passage 20 into the room. Further, the main body 50 is formed with a second intake port 21a for taking indoor air or outdoor air into the desorption air passage 21 and a second air outlet 21b for discharging the air flowing through the desorption air passage 21 to the outside. ing. The cooler 4 is near the first intake port 20a, the first blower 5 is near the first air outlet 20b, the condenser 2 is near the second air inlet 21a, and the second air outlet 21b. The 2nd ventilation means 6 is each arrange | positioned in the vicinity.

  The compressor 1 sucks the refrigerant and compresses the refrigerant to a high temperature / high pressure state, and may be composed of, for example, an inverter compressor capable of capacity control. The condenser 2 performs heat exchange between the air taken into the desorption air passage 21 by the second air blowing means 6 and the refrigerant, and condenses and liquefies the refrigerant. The expansion device 3 has a function as a pressure reducing valve or an expansion valve, and expands the refrigerant by reducing the pressure. The expansion device 3 may be constituted by a device whose opening degree can be variably controlled, for example, an electronic expansion valve. The cooler 4 exchanges heat between the air taken into the adsorption air passage 20 by the first blower 5 and the refrigerant, and evaporates the refrigerant.

  The first blowing means 5 is constituted by a fan such as a fan, takes indoor air into the adsorption air passage 20, passes the indoor air in the order of the cooler 4, the first rotor 7, and the second rotor 8, and again indoors. To supply. The second blowing means 6 is constituted by a blower such as a fan, takes indoor air or outdoor air into the desorption air passage 21, and passes the air in the order of the condenser 2, the second rotor 8, and the first rotor 7, It is discharged outside. The first rotor 7 and the second rotor 8 carry an adsorbent, adsorb moisture from indoor air flowing through the adsorption air passage 20, and desorb moisture adsorbed by indoor air or outdoor air flowing through the desorption air passage 21. It has a function to do. As the first rotor 7 and the second rotor 8, for example, a desiccant rotor having a honeycomb structure having air permeability in the axial direction is preferable.

  The adsorption / desorption air passage partition 9 blocks the adsorption air passage 20 and the desorption air passage 21, that is, forms the adsorption air passage 20 and the desorption air passage 21 in the main body 50. However, since the first rotor 7 and the second rotor 8 are provided so as to straddle the adsorption air passage 20 and the desorption air passage 21, the adsorption air passage 20 and the desorption air passage 21 correspond to the first rotor 7 and the first rotor 7. The two rotors 8 are related. The adsorption side airway partition 10 prevents the air taken in from the first intake port 20a from bypassing the first rotor 7 and the second rotor 8 and being supplied into the room from the first outlet 20b. . The desorption side air passage partition 11 prevents the air taken in from the second intake port 21a from being discharged from the second air outlet 21b to the outside, bypassing the first rotor 7 and the second rotor 8. .

Operation | movement of the air conditioning apparatus 100 is demonstrated.
When the 1st ventilation means 5 drives, indoor air is taken in in the adsorption | suction air path 20 from the 1st inlet 20a. This air is cooled and dehumidified by the cooler 4 to become air having a high relative humidity, and is guided to the first rotor 7. The moisture contained in the air having a high relative humidity is adsorbed by the second rotor 8 after being adsorbed by the capillary condensation action on the adsorption surface of the first rotor 7. The air taken into the adsorption air passage 20 is adsorbed by the first rotor 7 and the second rotor 8 to be supplied into the room from the first outlet 20b as air having a small moisture content. Thus, in the air conditioning apparatus 100, the indoor dehumidifying operation is performed.

  On the other hand, when the 2nd ventilation means 6 drives, indoor air or outdoor air is taken in in the desorption air path 21 from the 2nd inlet 21a. The air is heated by the condenser 2 to become air having a low relative humidity, and is guided to the second rotor 8. After the moisture adsorbed on the second rotor 8 is desorbed by the air having a low relative humidity, it is similarly desorbed by the first rotor 7. That is, the air taken into the desorption air passage 21 is used to dry the first rotor 7 and the second rotor 8. This air is blown out of the room from the second outlet 21b in a state containing the desorbed moisture.

  As described above, in the air conditioner 100, the first rotor 7 and the second rotor 8 are rotated around the axis so that the moisture is released by the desorption air passage 21 while adsorbing the water by the adsorption air passage 20, and the room. Can be dehumidified continuously. The first rotor 7 and the second rotor 8 are rotatably arranged so as to straddle the adsorption air passage 20 and the desorption air passage 21, and regions where air flowing through the adsorption air passage 20 is introduced by rotating ( For example, the area 7a shown in FIG. 5 or the like) and the area (for example, the area 7c shown in FIG. 5) into which the air flowing through the desorption air passage 21 is introduced are changed.

  FIG. 2 is a perspective view schematically showing the first rotor 7 and the second rotor 8. FIG. 3 is a graph showing an example of an isothermal adsorption line of the adsorbent carried on the first rotor 7 and the second rotor 8. FIG. 4 is a graph showing an example of the characteristics of the adsorbent carried on the first rotor 7 and the second rotor 8. Based on FIGS. 2-4, the structure and function of the 1st rotor 7 and the 2nd rotor 8 are demonstrated in detail. In FIG. 3, the horizontal axis represents relative humidity, and the vertical axis represents the equilibrium adsorption amount. In FIG. 4, the horizontal axis represents time, and the vertical axis represents the amount of moisture adsorption. Here, the case where the first rotor 7 and the second rotor 8 are desiccant rotors having a honeycomb structure having air permeability in the axial direction is shown as an example.

  The first rotor 7 and the second rotor 8 are rotatably supported in the same direction by a shaft 51 inserted through the central portion, and are installed so as to straddle the adsorption air passage 20 and the desorption air passage 21. Therefore, by rotating the first rotor 7 and the second rotor 8, it is possible to cause the surface on the adsorption air passage 20 side to function as an adsorption surface and the surface on the desorption air passage 21 side to function as a desorption surface. That is, the first rotor 7 and the second rotor 8 adsorb moisture from the air flowing through the adsorption air passage 20 on the adsorption surface, and rotate to change the adsorption surface to the desorption air passage 21 side to form a desorption surface. Moisture is desorbed by the air flowing through the air passage 21.

  In the first rotor 7 and the second rotor 8, for example, an adsorbent such as a porous substrate made of zeolite, silica gel, mesoporous inorganic material, activated carbon or the like is attached to a ceramic substrate or the like, or is made into paper. Use a good one. The adsorbent carried on the first rotor 7 and the second rotor 8 has a moisture content determined by the relative humidity. Therefore, in the first rotor 7 and the second rotor 8, moisture is adsorbed and desorbed according to the exposed air relative humidity. When an adsorbent as shown in FIG. 3 is used, water of wa (kg / kg) can be held in an environment of relative humidity a, but water of wb (kg / kg) can be held in an environment of relative humidity b. Therefore, when the relative humidity of the surrounding environment changes from a to b, in the equilibrium state, the rotor adsorbs moisture by the amount of (Wb−Wa), and the surroundings are dehumidified.

  As an adsorbent as shown in FIG. 3, there is a mesoporous inorganic material. This mesoporous inorganic material is silica with fine cylindrical holes with a diameter of about 1 to 3 nm (nanometers), and a region with a small relative humidity (relative humidity is 30% to 40%) due to capillary condensation phenomenon of the fine holes. ) Has a feature that the moisture absorption characteristic changes sharply. Other adsorbents include silica gel and zeolite. Silica gel is characterized by an increased amount of adsorption in a high humidity range. In contrast to silica gel, zeolite has a feature that it has an almost constant adsorption amount in a wide humidity range.

  FIG. 4 shows the amount of adsorption (total) when high humidity air is exposed to the adsorbent. As shown in FIG. 4, the maximum capacity capable of adsorbing moisture by the adsorbent is determined. There is a similar tendency for desorption. Therefore, in the air conditioner 100, the rotational speeds of the first rotor 7 and the second rotor 8 are individually determined so as to obtain the maximum dehumidifying capacity. The higher the relative humidity of the air guided to the adsorbent, the faster the rotation speed is reached because the adsorption capacity of the adsorbent is reached earlier. On the other hand, when the relative humidity of the air led to the adsorbent is low, the rotation speed is slowed down.

  In the air conditioner 100, air having a high relative humidity is guided to the adsorbent carried on the first rotor 7, so that the rotation speed is fast, and the adsorbent carried on the second rotor 8 has a low relative humidity. Since air is guided, the rotation speed is slowed down. Thus, in the air conditioning apparatus 100, the rotational speed of the first rotor 7 and the rotational speed of the second rotor 8 are individually determined and controlled. Therefore, in the air conditioning apparatus 100, it is possible to obtain a higher dehumidifying capacity by controlling each of the two moisture adsorbing means at an individual rotation speed than that in which the two moisture adsorbing means are rotated at the same speed. become.

  FIG. 5 is an explanatory diagram for explaining moisture adsorption / desorption in the first rotor 7 and the second rotor 8. FIG. 6 is an explanatory diagram for explaining an effect generated by rotation (direction / speed) of the rotor. FIG. 7 is a graph showing the rotation MAP of the rotor with respect to the surrounding environment of the rotor (temperature of ambient air / relative humidity). FIG. 8 is a graph for explaining the adsorption rate with a mesoporous inorganic material. FIG. 9 is a graph showing the moisture adsorption amount when the rotation speed of the first rotor 7 and the rotation speed of the second rotor 8 are changed. Based on FIG. 2 and FIGS. 5 to 9, the individual rotation control of the first rotor 7 and the second rotor 8 will be described based on the surrounding environment of the first rotor 7 and the second rotor 8. In FIG. 7, the horizontal axis represents relative humidity and the vertical axis represents temperature. 8 and 9, the horizontal axis represents time (minutes), and the vertical axis represents the amount of moisture adsorption (g / g).

  In FIG. 2, the first rotor 7 and the second rotor 8 are rotated in the same direction by the shaft 51, and in FIG. 5, the first rotor 7 and the second rotor 8 are rotated in the reverse direction by the shaft 51. Each state is shown. As described above, the rotation of the first rotor 7 and the second rotor 8 is individually controlled. That is, the first rotor 7 and the second rotor 8 can also be rotated in the same direction (clockwise indicated by the arrow in FIG. 2), and the first rotor 7 can be rotated counterclockwise (arrow A shown in FIG. 5). In addition, each of the second rotors 8 can be rotated in the clockwise direction (arrow B shown in FIG. 5).

  In the first rotor 7, the portion (area 7 b) on the adsorption surface near the completion of adsorption has a larger amount of moisture than the portion (area 7 a) on the adsorption surface immediately after completion of desorption. Similarly, in the second rotor 8, the portion of the adsorption surface (area 8 b) near the completion of adsorption has a larger amount of water than the portion (area 8 a) of the adsorption surface immediately after completion of desorption. Further, the portion (area 8c) on the suction surface immediately after the completion of the adsorption of the second rotor 8 has a larger amount of moisture than the portion (area 7c) on the adsorption surface near the completion of the desorption of the first rotor 7. Further, the air that has passed around the area 7b reaches around the area 8a almost horizontally (arrow C), and the air that has passed around the area 7a reaches around the area 8b almost horizontally (arrow D). The air that has passed through the periphery reaches the periphery of the area 7c almost horizontally (arrow E).

  In the area 7b, the amount of moisture is large, and in some cases, more moisture may not be sufficiently adsorbed. On the other hand, the amount of water is small in the area 7a, and more water can be adsorbed sufficiently. Therefore, the air that has passed through the area 7b may contain more water than the air that has passed through the area 7a. Similarly, the area 8b has a large amount of moisture, and in some cases, more moisture than this may not be sufficiently adsorbed. On the other hand, in the area 8a, the amount of moisture is small, and more moisture can be adsorbed sufficiently.

  That is, in order to increase the total amount of adsorption (both the first rotor 7 and the second rotor 8) in the air conditioner 100, it is desirable that more moisture can be adsorbed by the second rotor 8. Therefore, in the air conditioner 100, the rotation direction of the first rotor 7 and the rotation direction of the second rotor 8 can be rotated in reverse. By doing in this way, the water | moisture content contained in the air which passed the 1st rotor 7 can be adsorb | sucked efficiently by the 2nd rotor 8, and it can ensure the adsorption capacity of the air conditioning apparatus 100 whole, High dehumidification ability is obtained.

  FIG. 8 shows the adsorption rate when a mesoporous inorganic material is used as the adsorbent. FIG. 8A shows that when the ambient environment is a temperature of 25 ° C. and a relative humidity of 80%, the moisture adsorption amount is about 0.2 in a time of about 1.5 minutes. FIG. 8B shows that when the ambient environment is 25 ° C. and the relative humidity is 40%, it takes about 3 minutes for the moisture adsorption amount to be about 0.2. Therefore, as shown in FIG. 9, in the air conditioner 100, the rotation speed of the first rotor 7 is increased and the rotation speed of the second rotor 8 is decreased using the difference in adsorption speed depending on the surrounding environment. Can be determined. For example, assuming that the area on the suction side and the desorption side of the rotor is 180 degrees, the first rotor 7 is 180 degrees in 1.5 minutes, that is, the rotation speed is 20 rotations / h, the second rotor 7 is 180 degrees in 3 minutes, That is, the rotation speed is preferably 10 rotations / h.

An example of rotor rotation control using the difference in adsorption speed depending on the surrounding environment will be described in more detail.
[Same direction rotation pattern]
When the ambient relative humidity is high, the amount of moisture in the air is large, and the rotor reaches the saturated adsorption amount quickly, so that early desorption is effective and high-speed rotation is good. In addition, when the relative humidity is high, the amount of water adsorbed by the first rotor 7 and the second rotor 8 is large, and the air that has passed through the second rotor 8 at the time of desorption has a high relative humidity. When the first rotor 7 and the second rotor 8 are rotated in the reverse direction, the air desorbed by the second rotor 8 and has a high relative humidity and a large amount of water reaches the portion of the first rotor 7 where the amount of water is small just before the desorption is completed. However, there is a possibility that the first rotor 7 cannot be sufficiently detached. Decreasing the desorption performance deteriorates the adsorption performance by reducing the adsorption capacity of the rotor. As described above, the same direction rotation is good.

  When the ambient temperature is high, the temperature difference in the adsorption / desorption region is large, and it takes some time to reduce the relative humidity by heating the rotor that has shifted from adsorption to desorption in order to improve the desorption performance. Therefore, low speed rotation is good. In addition, when the ambient temperature is high, the amount of moisture in the air is large even at the same relative humidity as compared with the case where the ambient temperature is low (the moisture content is 2. The rotation in the same direction is relatively good due to the desorption performance.

[Reverse rotation pattern]
When the ambient relative humidity is low, the amount of moisture in the air is small, and a certain amount of time is required for the rotor to reach the saturated adsorption amount, and the performance can be ensured by rotating relatively slowly. Therefore, low speed rotation is sufficient. If the relative humidity is low, the amount of moisture adsorbed on the first rotor 7 and the second rotor 8 is small, and the air that has passed through the second rotor 8 at the time of desorption is not so high. The first rotor 7 and the second rotor 8 can be reversely rotated and can be detached and attached.

  Also, when the ambient temperature is low, the temperature difference in the adsorption / desorption region is small, and it takes much time to reduce the relative humidity by heating the rotor that has shifted from adsorption to desorption in order to improve the desorption performance. do not do. Therefore, high speed rotation is good. Furthermore, when the ambient temperature is low, the amount of water in the air is small even at the same relative humidity as compared with the case where the ambient temperature is high (the amount of water is 38% at 10 ° C compared to 25 ° C even at the same relative humidity 80%). Degree) Fully removable even in reverse direction.

  From the above, if the reverse rotation pattern is used at high humidity, air containing a certain amount of moisture that has passed through the area 8c cannot be efficiently desorbed in the area 7c with little moisture. Therefore, by using the same direction rotation pattern at high humidity, the area 7c can be efficiently desorbed even with air containing a certain amount of moisture that has passed through the area 8c at the start of desorption. On the other hand, when the humidity is low, the reverse rotation pattern is used, so that there is little moisture in the area 8c, and so much moisture is not desorbed. Therefore, since it is desorbed with air that does not contain much moisture, it can be desorbed even in the area 7c with little moisture. Moreover, reverse rotation is preferable for adsorption. Therefore, it is desirable that the first rotor 7 and the second rotor 8 be reversely rotated in total.

  In the system combined with the refrigeration cycle such as the air conditioner 100, when the ambient temperature is high, the cooling capacity / condensing capacity increases, the adsorption side becomes lower temperature, the desorption side becomes higher temperature, and the temperature difference in the adsorption / desorption area. On the contrary, when the ambient temperature is low, the cooling capacity / condensing capacity is lowered, and the temperature difference in the adsorption / desorption region is reduced. In addition, if the second rotor 8 is rotated at a low speed, the power consumption associated with the rotation can be reduced. Since the temperature and relative humidity around the first rotor 7 and the second rotor 8 are different depending on the season and time zone, the rotation of the first rotor 7 and the rotation of the second rotor 8 are individually performed according to the temperature and humidity. It is good to control.

  In the first embodiment, the adsorbent carried on the first rotor 7 and the adsorbent carried on the second rotor 8 are assumed to be the same, but the present invention is limited to this. Instead, adsorbents having different characteristics may be combined. If it does in this way, an adsorption effect can be improved further and it can contribute to improvement of dehumidification capability. For example, an adsorbent having the property of easily absorbing and desorbing moisture at high humidity is supported on the first rotor 7, and moisture adsorbing and desorbing at a lower humidity than the adsorbent supported on the first rotor 7 is supported on the second rotor 8. It is advisable to carry an adsorbent having the property of being easily processed. By carrying out like this, humidity can be reduced in steps and the dehumidification effect can be improved further.

  The air conditioner 100 includes a rotation drive unit (control device) (not shown) that rotates and drives the first rotor 7 and the second rotor 8 via the shaft 51. The ambient environment around the first rotor 7 and the second rotor 8 may be detected by providing a temperature sensor or a humidity sensor. Information detected by these sensors is sent as data to the rotation driving means and used for individual rotation control of the first rotor 7 and the second rotor 8.

  In the air conditioner 100a, in order to exchange heat between the area 40a and the area 41, the adsorption side airway partition 10 is provided at the leeward side end of the first communication pipe 30a. By providing the suction side air passage partition 10 at this position, the air taken into the suction air passage 20 can be guided to the area 41 and the area 40a.

This air is cooled and dehumidified by the cooler 4 to become air having a high relative humidity, and flows into the area 40. The air is guided to the first rotor 7, and moisture is adsorbed by the first rotor 7 to become low humidity, while the temperature rises due to adsorption heat and then flows into the area 41. The air flowing into the area 41 exchanges heat with the low-temperature air in the area 40a. That is, the area 41 is exposed to a low temperature environment (area 40a) through the first communication pipe 30a made of a metal material. By doing so, the temperature of the air in the area 41 can be lowered and the relative humidity can be raised.

  This air is guided to the second rotor 8, and moisture is similarly adsorbed by the second rotor 8. In the second rotor 8, air with an increased relative humidity is guided, so that the moisture adsorption performance can be improved. Then, this air is supplied into the room from the first outlet 20b through the area 42 as air having a small moisture content. Thus, in the air conditioning apparatus 100a, the indoor dehumidifying operation is performed.

  On the other hand, when the 2nd ventilation means 6 drives, indoor air or outdoor air is taken in in the desorption air path 21 from the 2nd inlet 21a. This air is heated by the condenser 2 to become air having a low relative humidity and flows into the area 43. The air is guided to the second rotor 8, and moisture is desorbed by the second rotor 8 to become high humidity, while the temperature is lowered by desorption heat and then flows into the area 44. The air flowing into the area 44 exchanges heat with the high-temperature air in the area 43a. That is, the area 44 is exposed to a high temperature environment (area 43a) through the second communication pipe 30b made of a metal material. By doing so, the temperature of the air in the area 44 can be raised and the relative humidity can be lowered.

  This air is guided to the first rotor 7, and moisture is also desorbed in the first rotor 7. In the first rotor 7, air with a reduced relative humidity is guided, so that the moisture desorption performance can be improved. Then, this air is blown out from the second air outlet 21b through the area 45 as air containing a lot of moisture. Thus, in the air conditioning apparatus 100a, the indoor dehumidifying operation is performed. As described above, in the air conditioner 100a, moisture can be released by the desorption air passage 21 while moisture is adsorbed by the adsorption air passage 20 to continuously perform dehumidification in the room.
