Description

  The present invention relates to a dehumidifying apparatus including a heat pump including a compressor, a radiator, an expansion mechanism, a heat absorber, and the like, and a moisture absorption / release unit that performs moisture absorption / release using an adsorbent or an absorbent.

  As a conventional dehumidifying device including a heat pump and moisture absorbing / releasing means, there is an apparatus that circulates air in the order of a radiator, a moisture releasing part of the moisture absorbing / releasing means, and a heat absorber (see, for example, Patent Document 1).

  Hereinafter, the dehumidifier will be described with reference to FIG.

As shown in FIG. 13, in the main body 101 of the dehumidifying apparatus, a compressor circuit 102, a radiator 103, an expansion mechanism 104, a refrigerant circuit 106 having a heat absorber 105 connected thereto, and a honeycomb rotor 108 on which an adsorbent 107 is supported. The circulation path 111 is formed so that the circulation air 110 blown by the circulation fan 109 circulates in the order of the radiator 103, a part of the honeycomb rotor 108, and the heat absorber 105. Further, the other part of the honeycomb rotor 108 is disposed in a supply path 114 that opens the suction port 112 and the air outlet 113, and the dehumidification target air 116 is supplied by the supply fan 115. In addition, the refrigerant circuit 106 is filled with a refrigerant 117, and the refrigerant 117 is compressed by the compressor 102, and thus circulates in the refrigerant circuit 106 in the order of the radiator 103, the expansion mechanism 104, and the heat absorber 105. In addition, the heat pump 118 is operated by radiating heat to the circulating air 110 in the radiator 103 and absorbing heat from the circulating air 110 in the heat absorber 105. The honeycomb rotor 108 is rotated by a driving means (not shown), and the adsorbent 107 carried on the honeycomb rotor 108 with this rotation is brought into contact with the circulating air 110 in the circulation path 111 and to be dehumidified in the supply path 114. The contact with the air 116 is repeated. This adsorbent 107 has a characteristic that it can retain a large amount of moisture if the relative humidity of the exposed air is high, and the amount of water that can be retained decreases when the relative humidity is low. If the contact is repeated, moisture adsorption / desorption is performed according to the difference in the amount of moisture that can be held by the adsorbent 107 at each relative humidity. Here, the circulating air 110 in contact with the adsorbent 107 in the circulation path 111 is heated by the heat radiation of the refrigerant 117 in the radiator 103 and becomes air having a relative humidity lower than that of the air to be dehumidified 116. Due to the difference in humidity, the adsorbent 107 acts to adsorb moisture in the dehumidified air 116 and desorb the adsorbed moisture into the circulating air 110. The moisture absorption / desorption means 119 is operated by this adsorption / desorption action, and the portion located in the supply path 114 of the honeycomb rotor 108 absorbs moisture from the dehumidification target air 116, and the circulation path of the honeycomb rotor 108 The part located in 111 becomes the moisture release part 121 which releases moisture to the circulating air 110. The dehumidification target air 116 absorbed by the moisture absorption unit 120 becomes low-humidity air and flows out of the main body 101 from the air outlet 113, and the circulating air 110 dehumidified by the moisture release unit 121 includes high-humidity air. And is supplied to the heat absorber 105. The high-humidity circulating air 110 supplied to the heat absorber 105 is cooled to the dew point temperature or less by the heat absorption of the refrigerant 117, and the moisture in the air is saturated. This saturated water is condensed and dropped into the tank 122, and the amount of condensed water accumulated in the tank 122 becomes the dehumidifying amount of the dehumidifying device.

(Embodiment 1)
FIG. 1 is a diagram illustrating a schematic configuration of a dehumidifier according to Embodiment 1 of the present invention. As shown in FIG. 1, a refrigerant circuit 106 in which a compressor 102, a radiator 103, an expansion mechanism 104, and a heat absorber 105 are connected to a pipe in a main body 101 of the dehumidifier, a moisture absorption unit 120 that absorbs moisture from the supply air, and supply air A moisture absorbing / releasing means 119 having a moisture releasing portion 121 for releasing moisture is provided, and the refrigerant circuit 106 is filled with the refrigerant 117. Further, the main body 101 is provided with a suction port 112 and an air outlet 113, and the fan 1 is operated to suck the dehumidification target air 116 into the main body 101 from the suction port 112, and the radiator 103 and the first dehumidifying unit 121. After supplying the moisture release area 2, the second moisture release area 3 of the moisture release part 121, the heat absorber 105, and the moisture absorption part 120 in this order, an air path is formed so as to blow out from the air outlet 113 to the outside of the main body 101. Further, an air path is formed in the first moisture release area 2 and the second moisture release area 3 so as to supply the dehumidification target air 116 from the opposite direction, thereby reducing the number of inversions of the dehumidification target air 116. Then, by compressing the refrigerant 117 by the compressor 102, the refrigerant 117 circulates in the refrigerant circuit 106 in the order of the radiator 103, the expansion mechanism 104, and the heat absorber 105, and the dehumidification target air 116 supplied to the radiator 103. The heat pump 118 is activated by radiating heat to the heat absorber 105 and absorbing heat from the dehumidification target air 116 supplied to the heat absorber 105.

  FIG. 2 is a diagram showing a detailed configuration of the moisture absorption / release means 119. The moisture absorbing / releasing means 119 includes a cylindrical honeycomb rotor 108 that is capable of ventilating in the axial direction on which the adsorbent 107 is supported, and the honeycomb rotor 108 is rotatably supported by the rotating shaft 4. And the gear 5 is formed in the outer periphery of the honeycomb rotor 108, and the belt 8 is wound around the gear part 7 of the drive motor 6 that rotationally drives the gear 5. Further, the honeycomb rotor 108 is divided into a moisture absorbing part 120, a first moisture releasing area 2 of the moisture releasing part 121, and a second moisture releasing area 3 of the moisture releasing part 121, thereby suppressing mutual circulation of air supplied thereto. So as to partition the air path. When the fan 1 is operated, the dehumidification target air 116 (a) that has passed through the radiator 103 in the first moisture release area 2 and the dehumidification target air 116 (in the second moisture release area 3 that has passed through the first moisture release area 2). b) The dehumidifying target air 116 (c) that has passed through the heat absorber 105 is supplied to the hygroscopic section 120. Here, when the drive motor 6 is driven, the driving force is transmitted to the gear 5 through the belt 8 to rotate the honeycomb rotor 108, and the adsorbent 107 is supplied to the first moisture release region 2 by this rotation. The contact is repeated in the order of the air 116 (a), the dehumidification target air 116 (b) supplied to the second moisture release region 3, and the dehumidification target air 116 (c) supplied to the moisture absorption unit 120. This adsorbent 107 has a characteristic that it can retain a large amount of moisture if the relative humidity of the exposed air is high, and the amount of water that can be retained decreases when the relative humidity is low. If the contact is repeated, moisture adsorption / desorption is performed according to the difference in the amount of moisture that can be held by the adsorbent 107 at each relative humidity. Here, the dehumidification target air 116 (a) in contact with the adsorbent 107 in the first moisture release region 2 is high-temperature and low-relative-humidity air heated by the heat radiation of the refrigerant 117 in the radiator 103. The dehumidification target air 116 (c) that comes into contact with the adsorbent 107 is low-temperature and high-relative-humidity air cooled by the heat absorption of the refrigerant 117 in the heat absorber 105. Therefore, due to the difference in relative humidity between these airs, The adsorption / desorption action of the adsorbent 107 is performed, and the moisture absorption / desorption means 119 operates. Next, the operation of the dehumidifier will be described.

  FIG. 3 is a Mollier diagram (pressure-enthalpy diagram) showing a change in state of the refrigerant 117 of the dehumidifier shown in FIG. A cycle in which points A, B, C, and D shown in FIG. 3 are connected by arrows indicates a change in state of the refrigerant 117 circulating in the refrigerant circuit 106, and the refrigerant 117 is compressed by the compressor 102. As a result, the pressure and enthalpy rise to change the state from point A to point B, and the enthalpy is reduced by dissipating heat to the dehumidification target air 116 supplied in the radiator 103, and from point B to point C. It becomes the state of. Next, when the expansion mechanism 104 expands and depressurizes, the pressure decreases to change the state from point C to point D, and the enthalpy increases by absorbing heat from the dehumidification target air 116 supplied by the heat absorber 105. The state returns from the point D to the point A. Due to the state change of the refrigerant 117, the heat pump 118 that absorbs heat in the heat absorber 105 and radiates heat in the radiator 103 operates. At this time, a value obtained by multiplying the enthalpy difference between the points B and C by the circulation amount of the refrigerant 117 Is the heat dissipation amount in the radiator 103, and the value obtained by multiplying the enthalpy difference between the points A and D (point C) by the circulation amount of the refrigerant 117 is the heat absorption amount in the heat absorber 105, that is, the difference between the heat dissipation amount and the heat absorption amount, that is, the point B A value obtained by multiplying the enthalpy difference between the point A and the circulatory amount of the refrigerant 117 becomes the compression work amount of the compressor 102.

  FIG. 4 is a moist air diagram showing a change in state of the dehumidifying target air 116 in the dehumidifying apparatus shown in FIG. In the wet air diagram shown in FIG. 4, first, the dehumidification target air 116 in the state of point a is supplied to the radiator 103 and heated by the heat radiation of the refrigerant 117 to be in the state of point b. The dehumidification target air 116 in the state of point b is then supplied to the first moisture release region 2 of the moisture release unit 121 to desorb moisture held by the adsorbent 107 carried on the honeycomb rotor 108. As the humidity increases, the temperature decreases and the point c is reached. The dehumidification target air 116 that has reached the state of point c is further humidified by being desorbed again by being supplied to the second moisture release region 3 of the moisture release unit 121 and desorbing the moisture held by the adsorbent 107. As the humidity rises, the temperature drops to a point d. The dehumidification target air 116 that has reached the point d is then supplied to the heat absorber 105 and is cooled to the dew point temperature or lower by the heat absorption of the refrigerant 117 and becomes saturated at point e. The water saturated at this time is collected in the tank 122 as condensed water. The dehumidification target air 116 that has become saturated at the point e is then supplied to the moisture absorption unit 120, and is dehumidified by adsorbing moisture to the adsorbent 107. As a result, the humidity decreases and the temperature rises. Of dry air. The dehumidifying target air 116 that has reached the point f is sucked into the fan 1 and discharged outside the apparatus. In the state change of the dehumidifying target air 116 described above, the amount of condensed water recovered in the heat absorber 105 is a value obtained by multiplying the absolute humidity difference between the point d and the point e by the weight-converted air volume of the dehumidifying target air 116, thereby releasing moisture. The moisture release amount in the unit 121 is a value obtained by multiplying the absolute humidity difference between the points b and d by the weight-converted air volume of the dehumidifying target air 116. Further, the moisture absorption amount in the moisture absorption unit 120 is a value obtained by multiplying the absolute humidity difference between the points e and f by the weight-converted air volume of the dehumidifying target air 116. The moisture release amount in the first moisture release region 2 of the moisture release unit 121 is a value obtained by multiplying the absolute humidity difference between the points b and c by the weight-converted air volume of the dehumidification target air 116, and the second release of the moisture release unit 121. The moisture release amount in the wet region 3 is a value obtained by multiplying the absolute humidity difference between the points c and d by the weight-converted air volume of the dehumidifying target air 116. Here, the air at the point b indicating the inlet air state of the first moisture release region 2 is heated to a higher temperature than the air at the point c indicating the inlet air state of the second moisture release region 3, so the first moisture release region. The moisture release amount in 2 tends to increase with respect to the moisture release amount in the second moisture release region 3.

  In the above operation, in the ideal state, the point d indicating the outlet air state of the moisture releasing unit 121 approaches the point d ′ having the same relative humidity as the point e indicating the inlet air state of the moisture absorbing unit 120, and the moisture absorbing unit 120. The point f that indicates the outlet air state of the water is close to the point f ′ that has the same relative humidity as the point b that indicates the inlet air state of the moisture release unit 121. Therefore, the relative humidity at the point e is increased and the relative humidity at the point b is decreased, that is, the supply air to the moisture absorption unit 120 indicated by the point e and the supply air to the moisture release unit 121 indicated by the point b. Enlarging the relative humidity difference increases the amount of moisture absorbed and released, resulting in improved dehumidification efficiency. Further, the value obtained by multiplying the enthalpy difference between the points a and b by the weight-converted air volume of the dehumidified air 116 is multiplied by the heat dissipation amount in the radiator 103, and the enthalpy difference between the points d and e is multiplied by the weight-converted air volume of the dehumidified air 116. The heat absorption amount in the heat absorber 105 becomes the heat dissipation amount in the heat sink 103 and the heat absorption amount in the heat absorber 105 are equal to the heat dissipation amount and the heat absorption amount obtained from the state change of the refrigerant 117 in FIG. Therefore, after supplying the dehumidification target air 116 to the first moisture release region 2, the second release is performed again after supplying the dehumidification target air 116 to the first moisture release region 2. By supplying and supplementing the moisture region 3, the air volume of the dehumidifying target air 116 can be set to an optimum value in each process of heat dissipation in the radiator 103, heat absorption in the heat absorber 105, and moisture absorption in the moisture absorber 120. It is.

  As described above, with the configuration and operation described above, the dehumidifier of this embodiment has the following effects.

  The air to be dehumidified 116 is heated by the heat dissipation of the heat pump 118 in the radiator 103, then humidified by the moisture absorption / release means 119 in the moisture release unit 121, and then cooled by the heat absorption of the heat pump 118 in the heat absorber 105. Next, by dehumidifying the moisture absorbing section 120 by absorbing moisture by the moisture absorbing / releasing means 119, the relative humidity difference between the dehumidifying target air 116 supplied to the moisture absorbing section 120 and the dehumidifying target air 116 supplied to the moisture releasing section 121 is determined. The moisture absorption / release amount of the moisture absorption / release means 119 can be increased with a simple configuration that does not provide the circulation path 111. Furthermore, by supplying more air than the dehumidification target air 116 supplied to the heat absorber 105 to the moisture release unit 121, an air volume suitable for moisture release of the moisture absorption / release means 119 and an air volume suitable for heat absorption of the heat pump 118 Can be eliminated and efficient dehumidification can be performed.

  In addition, the air to be dehumidified 116 is heated by the heat dissipation of the heat pump 118 in the radiator 103, and then humidified by the moisture absorbing / releasing means 119 in the moisture releasing section 121, and then in the heat absorber 105 by the heat absorption of the heat pump 118. Relative humidity between the dehumidification target air 116 supplied to the moisture absorption unit 120 and the dehumidification target air 116 supplied to the moisture release unit 121 by cooling and then dehumidifying the moisture absorption unit 120 by absorbing moisture by the moisture absorption / release unit 119. The difference can be enlarged, and the moisture absorption / release amount of the moisture absorption / release means 119 can be increased with a simple configuration in which the circulation path 111 is not provided. Further, by supplying more air than the dehumidification target air 116 supplied to the moisture absorption unit 120 to the moisture release unit 121, the air volume suitable for moisture release by the moisture absorption / release unit 119 and the moisture absorption by the moisture absorption / release unit 119 are improved. Eliminates imbalance with the appropriate air volume and can perform efficient dehumidification.

  In addition, the air to be dehumidified 116 is heated by the heat dissipation of the heat pump 118 in the radiator 103, and then humidified by the moisture absorbing / releasing means 119 in the moisture releasing section 121, and then in the heat absorber 105 by the heat absorption of the heat pump 118. Relative humidity between the dehumidification target air 116 supplied to the moisture absorption unit 120 and the dehumidification target air 116 supplied to the moisture release unit 121 by cooling and then dehumidifying the moisture absorption unit 120 by absorbing moisture by the moisture absorption / release unit 119. The difference can be enlarged, and the moisture absorption / release amount of the moisture absorption / release means 119 can be increased with a simple configuration in which the circulation path 111 is not provided. Further, by supplying more air than the dehumidification target air 116 supplied to the radiator 103 to the moisture release unit 121, an air volume suitable for moisture release of the moisture absorption / release means 119, and an air volume suitable for heat dissipation of the heat pump 118, Can be eliminated and efficient dehumidification can be performed.

  In addition, the air to be dehumidified 116 is heated by the heat dissipation of the heat pump 118 in the radiator 103, then humidified by the moisture absorption / release means 119 in the first moisture release region 2 of the moisture release unit 121, and then the moisture release In the second moisture release region 3 of the part 121, the moisture absorption / release means 119 further humidifies, then the heat absorber 105 cools by the heat absorption of the heat pump 118, and then in the moisture absorption part 120, the moisture absorption / release means 119 absorbs moisture. By simply dehumidifying, the relative humidity difference between the dehumidification target air 116 supplied to the moisture absorption unit 120 and the dehumidification target air 116 supplied to the first moisture release region 2 is expanded, and the simple configuration in which the circulation path 111 is not provided Thus, the moisture absorption / release amount of the moisture absorption / release means 119 can be increased. Furthermore, by supplying the dehumidification target air 116 to the moisture release unit 121 a plurality of times, the air volume suitable for moisture release of the moisture absorption / release means 119 and the air volume suitable for heat absorption / release of the heat pump 118 and moisture absorption / release of the moisture absorption / release means 119 are determined. Balance can be eliminated and efficient dehumidification can be performed.

  Moreover, the frequency | count of inversion of the ventilation direction of the dehumidification object air 116 can be decreased by comprising the 1st moisture release area | region 2 passage direction and the 2nd moisture release area 3 passage direction in the opposite direction of the dehumidification object air 116. As a result, the air passage configuration can be simplified and the apparatus can be miniaturized.

  Further, in the moisture absorbing / releasing means 119, the adsorbent 107 carried by the honeycomb rotor 108 adsorbs moisture from the dehumidified air 116 in the moisture absorbing section 120 and desorbs moisture to the dehumidified air 116 in the moisture releasing section 121. The honeycomb rotor 108 is disposed on the honeycomb rotor 108, and the moisture absorption in the moisture absorption section 120 and the moisture desorption in the moisture release section 121 are repeated by the rotation of the honeycomb rotor 108. The moisture adsorption of the adsorbent 107 in the unit 120 and the moisture desorption of the adsorbent 107 in the moisture releasing unit 121 can be easily repeated, and the dehumidifier can be configured at low cost.

  In addition, the adsorbent 107 moves in the order of the hygroscopic portion 120, the first moisture release area 2, and the second moisture release area 3 by the rotation of the honeycomb rotor 108, so that the moisture release in the first moisture release area 2 is achieved. It becomes easier to increase the amount than the moisture release amount in the second moisture release region 3. Thereby, the rotation direction of the honeycomb rotor 108 can be easily adapted to the configuration in which the moisture release amount to the dehumidification target air 116 in the first moisture release region 2 is increased.

  The adsorbent 107 supported on the honeycomb rotor 108 of the present embodiment may be a substance that has a hygroscopic property and can be supported on the honeycomb rotor 108 and has a certain degree of heat resistance for moisture desorption. Inorganic adsorption type hygroscopic agents such as silica gel and zeolite, hygroscopic agents such as organic polymer electrolytes (ion exchange resins), and absorbent hygroscopic agents such as lithium chloride can be used. Furthermore, the adsorbent 107 is not limited to one type, and two or more types of the adsorbent 107 described above may be used in combination.

However, the number of times the dehumidification target air 116 is supplied to the moisture desorption unit 121 is not limited to two, and is necessary. Depending on the case, it may be supplied three times, four times, five times, and so on.

The adsorbent 107 may repeat contact in the order of the dehumidification target air 116 (a). In this case, since the adsorbent 107 that has sufficiently adsorbed moisture at the time of contact with the dehumidification target air 116 (c) in the moisture absorption unit 120 moves to the second moisture release region 3, the adsorption agent is compared with the present embodiment. The amount of moisture desorbed to the dehumidification target air 116 (b) supplied to the second moisture release area 3 of the adsorbent 107 increases, and the dehumidification target air 116 (a) supplied to the first moisture release area 2 of the adsorbent 107 It tends to decrease the amount of moisture desorbed in the water.

As shown in FIG. 5, a refrigerant circuit 106 in which a compressor 102, a radiator 103, an expansion mechanism 104, and a heat absorber 105 are connected in a pipe in a main body 101 of the dehumidifier, a moisture absorbing unit 120 that absorbs moisture from the supply air, and supply air A moisture absorbing / releasing means 119 having a moisture releasing part 121 for releasing moisture is provided, and the refrigerant circuit 106 is filled with carbon dioxide as the refrigerant 117. Further, the main body 101 is provided with an inlet 112 and an outlet 113, and the fan 1 is operated to suck the dehumidification target air 116 from the inlet 112 into the main body 101, and the refrigerant inflow side of the radiator 103, the moisture release portion. The first moisture release area 2 of 121, the refrigerant outflow side of the radiator 103, the second moisture release area 3 of the moisture release part 121, the heat absorber 105, and the moisture absorption part 120 are supplied in this order, and then from the blower outlet 113 to the outside of the main body 101. An air path is formed so as to blow out, and the dehumidification target air 116 is supplied to the first moisture release area 2 and the second moisture release area 3 from the same direction. Then, by compressing the refrigerant 117 by the compressor 102, the refrigerant 117 circulates in the refrigerant circuit 106 in the order of the radiator 103, the expansion mechanism 104, and the heat absorber 105, and the dehumidification target air 116 supplied to the radiator 103. The heat pump 118 is activated by radiating heat to the heat absorber 105 and absorbing heat from the dehumidification target air 116 supplied to the heat absorber 105.

  FIG. 6 is a diagram showing a detailed configuration of the moisture absorption / release means 119. The moisture absorbing / releasing means 119 includes a cylindrical honeycomb rotor 108 that is capable of ventilating in the axial direction on which the adsorbent 107 is supported, and the honeycomb rotor 108 is rotatably supported by the rotating shaft 4. And the gear 5 is formed in the outer periphery of the honeycomb rotor 108, and the belt 8 is wound around the gear part 7 of the drive motor 6 that rotationally drives the gear 5. Further, the honeycomb rotor 108 is divided into a moisture absorbing part 120, a first moisture releasing area 2 of the moisture releasing part 121, and a second moisture releasing area 3 of the moisture releasing part 121, thereby suppressing mutual circulation of air supplied thereto. So as to partition the air path. When the fan 1 is operated, the dehumidification target air 116 (a) that has passed through the refrigerant inflow side of the radiator 103 into the first moisture release area 2 and the refrigerant outflow side of the radiator 103 has passed through the second moisture release area 3. The dehumidification target air 116 (b) and the dehumidification target air 116 (c) that have passed through the heat absorber 105 are supplied to the moisture absorption unit 120, respectively. Here, when the drive motor 6 is driven, the driving force is transmitted to the gear 5 through the belt 8 to rotate the honeycomb rotor 108, and the adsorbent 107 is supplied to the first moisture release region 2 by this rotation. The contact is repeated in the order of the air 116 (a), the dehumidification target air 116 (b) supplied to the second moisture release region 3, and the dehumidification target air 116 (c) supplied to the moisture absorption unit 120. This adsorbent 107 has a characteristic that it can retain a large amount of moisture if the relative humidity of the exposed air is high, and the amount of water that can be retained decreases when the relative humidity is low. If the contact is repeated, moisture adsorption / desorption is performed according to the difference in the amount of moisture that can be held by the adsorbent 107 at each relative humidity. Here, the dehumidification target air 116 (a) in contact with the adsorbent 107 in the first moisture release area 2 and the dehumidification target air 116 (b) in contact with the adsorbent 107 in the second moisture release area 3 are transmitted in the radiator 103. The air to be dehumidified 116 (c), which is high-temperature and low-relative-humidity air heated by the heat dissipation of the refrigerant 117 and contacts the adsorbent 107 in the hygroscopic section 120, is cooled by the heat absorption of the refrigerant 117 in the heat absorber 105. Since the air has a high relative humidity, the adsorption / desorption action of the adsorbent 107 is performed by the difference in relative humidity between the airs, and the moisture absorption / release means 119 operates. Next, the operation of the dehumidifier will be described.

  FIG. 7 is a Mollier diagram (pressure-enthalpy diagram) showing a change in state of the refrigerant 117 of the dehumidifier shown in FIG. A cycle in which point A, point B, point C, point D, and point E shown in FIG. 7 are connected by arrows indicates a change in the state of carbon dioxide as the refrigerant 117 circulating in the refrigerant circuit 106. The carbon dioxide refrigerant is compressed to a supercritical pressure higher than the critical pressure in the compressor 102 to change the state from point A to point B, and then supplied to the first moisture releasing region 2 on the inflow side of the radiator 103. Although heat is dissipated to the dehumidification target air 116 (a), since it is in a supercritical state, even if heat is dissipated, the temperature falls without condensing and changes from point B to point C. Next, heat is dissipated to the dehumidification target air 116 (b) supplied to the second moisture release region 3 on the outflow side of the radiator 103. Similarly, since it is in a supercritical state, it does not condense even if radiated. The temperature drops to a state from point C to point D. When the expansion mechanism 104 expands and depressurizes, the pressure decreases to change the state from point D to point E, and the enthalpy increases by absorbing heat from the dehumidification target air 116 (c) supplied in the heat absorber 105. Then, the state returns from point E to point A. When a refrigerant that radiates heat at a supercritical pressure exemplified by carbon dioxide is used as the working fluid of the heat pump 118, the temperature in the radiator 103 after compression is high. For this reason, since the temperature of the dehumidification target air 116 heated in the radiator 103 is also increased and supplied to the moisture release unit 121 in a lower relative humidity state, the dehumidification target air 116 supplied to the moisture absorption unit 120 The relative humidity difference will increase. By increasing the difference in relative humidity, the moisture absorption / release amount of the moisture absorption / release means 119 is increased, and the dehumidification efficiency is further improved. Further, the supercritical working fluid exemplified by carbon dioxide has a characteristic that a temperature gradient is generated in the process of heat dissipation in the radiator 103. Accordingly, the refrigerant 117 has a high temperature on the inflow side of the radiator 103, and gradually decreases in temperature due to heat dissipation, and decreases on the outflow side of the radiator 103. For this reason, the dehumidification target air 116 (a) heated by the heat dissipation of the refrigerant 117 on the inflow side of the radiator 103 is similarly dehumidified target air 116 (b) heated by the heat dissipation of the refrigerant 117 on the outflow side of the radiator 103. ) In a hot air state. Due to the state change of the refrigerant 117 as described above, the heat pump 118 that absorbs heat in the heat absorber 105 and radiates heat in the radiator 103 operates, and at this time, the enthalpy difference between the points B and D is multiplied by the circulation amount of the refrigerant 117. The value is the amount of heat dissipation in the radiator 103, and the value obtained by multiplying the enthalpy difference between point A and point E (point D) by the circulation amount of the refrigerant 117 is the amount of heat absorption in the heat absorber 105. A value obtained by multiplying the enthalpy difference between B and point A by the circulation amount of the refrigerant 117 is the compression work amount of the compressor 102.

  FIG. 8 is a moist air diagram showing a change in the state of the dehumidifying target air 116 in the dehumidifying apparatus shown in FIG. In the wet air diagram shown in FIG. 8, first, the dehumidification target air 116 in the state of point a is supplied to the refrigerant 117 inflow side of the radiator 103 and is heated by the heat radiation of the refrigerant 117 to be in the state of point b. The dehumidification target air 116 in the state of point b is then supplied to the first moisture release region 2 of the moisture release unit 121 to desorb moisture held by the adsorbent 107 carried on the honeycomb rotor 108. As the humidity increases, the temperature decreases and the point c is reached. The dehumidification target air 116 in the state of point c is then supplied to the refrigerant 117 outflow side of the radiator 103 and is heated again by the heat release of the refrigerant to be in the state of point d. The dehumidification target air 116 that has reached the state of point d is supplied to the second moisture release region 3 of the moisture release unit 121 and is further humidified by desorbing the moisture held by the adsorbent 107 again. As the humidity rises, the temperature drops and the point e is reached. The dehumidification target air 116 that has reached the state of point e is then supplied to the heat absorber 105 and is cooled to the dew point temperature or lower by the heat absorption of the refrigerant 117 and becomes saturated at point f. The water saturated at this time is collected in the tank 122 as condensed water. The dehumidification target air 116 that has reached the saturated state at the point f is then supplied to the moisture absorbing unit 120 and dehumidified by adsorbing moisture to the adsorbent 107. As a result, the humidity decreases and the temperature rises. Of dry air. The dehumidifying target air 116 that has reached the point g is sucked into the fan 1 and discharged outside the apparatus. In the state change of the dehumidifying target air 116 described above, the amount of condensed water recovered in the heat absorber 105 is a value obtained by multiplying the absolute humidity difference between the points e and f by the weight-converted air volume of the dehumidifying target air 116, and the hygroscopic part. The moisture absorption amount at 120 is a value obtained by multiplying the absolute humidity difference between the points f and g by the weight-converted air volume of the dehumidifying target air 116. Further, the moisture release amount in the first moisture release region 2 of the moisture release unit 121 is a value obtained by multiplying the absolute humidity difference between the points b and c by the weight-converted air volume of the dehumidification target air 116, and the second release of the moisture release unit 121. The moisture release amount in the moisture release region 3 is a value obtained by multiplying the absolute humidity difference between the points d and e by the weight-converted air volume of the dehumidification target air 116. Here, the air at the point b indicating the inlet air state of the first moisture release region 2 is heated to a higher temperature than the air at the point d indicating the inlet air state of the second moisture release region 3, and therefore the first moisture release region 2. The moisture release amount tends to increase with respect to the moisture release amount in the second moisture release region 3.

  In the above operation, in the ideal state, the point e indicating the outlet air state of the moisture releasing unit 121 approaches the point e ′ having the same relative humidity as the point f indicating the inlet air state of the moisture absorbing unit 120, and the moisture absorbing unit 120. The point g that indicates the outlet air state of the gas approaches the point g ′ that has the same relative humidity as the point b that indicates the inlet air state of the moisture release unit 121. Therefore, the relative humidity at the point f is increased and the relative humidity at the point b is decreased, that is, the supply air to the moisture absorption unit 120 indicated by the point f and the supply air to the moisture release unit 121 indicated by the point b. Enlarging the relative humidity difference increases the amount of moisture absorbed and released, resulting in improved dehumidification efficiency. Further, an added value of a value obtained by multiplying the enthalpy difference between the points a and b by the weight-converted air volume of the dehumidified air 116 and a value obtained by multiplying the enthalpy difference between the points c and d and the weight-converted air volume of the dehumidified air 116 is obtained. A value obtained by multiplying the heat dissipation amount in the radiator 103 and the enthalpy difference between the points e and f by the weight-converted air volume of the air to be dehumidified 116 becomes the heat absorption amount in the heat absorber 105, and the heat dissipation amount in the heat radiator 103 and the heat absorption amount in the heat absorber 105. The amount of heat becomes equal to the heat release amount and the heat absorption amount obtained from the state change of the refrigerant 117 in FIG. Therefore, the heat release amount of the heat pump 118 and the moisture release amount of the moisture absorption / desorption means 119, which are insufficient for one supply of the dehumidification target air 116 in the radiator 103 and the moisture release unit 121, are supplied to the dehumidification target air via the radiator 103. 116 is supplied to the first moisture release area 2 and then supplied again to the second moisture release area 3 via the radiator 103 to supplement the heat absorption in the heat absorber 105 and the moisture absorption in the moisture absorber 120. The air volume of the dehumidifying target air 116 can be set to an optimum value.

  As described above, with the configuration and operation described above, the dehumidifier of this embodiment has the following effects.

  The air to be dehumidified 116 is heated by the heat dissipation of the heat pump 118 in the radiator 103, then humidified by the moisture absorption / release means 119 in the moisture release unit 121, and then cooled by the heat absorption of the heat pump 118 in the heat absorber 105. Next, by dehumidifying the moisture absorbing section 120 by absorbing moisture by the moisture absorbing / releasing means 119, the relative humidity difference between the dehumidifying target air 116 supplied to the moisture absorbing section 120 and the dehumidifying target air 116 supplied to the moisture releasing section 121 is determined. The moisture absorption / release amount of the moisture absorption / release means 119 can be increased with a simple configuration that does not provide the circulation path 111. Furthermore, by supplying more air than the dehumidification target air 116 supplied to the heat absorber 105 to the moisture release unit 121, an air volume suitable for moisture release of the moisture absorption / release means 119 and an air volume suitable for heat absorption of the heat pump 118 Can be eliminated and efficient dehumidification can be performed.

  In addition, the air to be dehumidified 116 is heated by the heat dissipation of the heat pump 118 in the radiator 103, and then humidified by the moisture absorbing / releasing means 119 in the moisture releasing section 121, and then in the heat absorber 105 by the heat absorption of the heat pump 118. Relative humidity between the dehumidification target air 116 supplied to the moisture absorption unit 120 and the dehumidification target air 116 supplied to the moisture release unit 121 by cooling and then dehumidifying the moisture absorption unit 120 by absorbing moisture by the moisture absorption / release unit 119. The difference can be enlarged, and the moisture absorption / release amount of the moisture absorption / release means 119 can be increased with a simple configuration in which the circulation path 111 is not provided. Further, by supplying more air than the dehumidification target air 116 supplied to the moisture absorption unit 120 to the moisture release unit 121, the air volume suitable for moisture release by the moisture absorption / release unit 119 and the moisture absorption by the moisture absorption / release unit 119 are improved. Eliminates imbalance with the appropriate air volume and can perform efficient dehumidification.

  In addition, the air to be dehumidified 116 is heated in the radiator 103 by the heat radiation of the heat pump 118, then humidified by the moisture absorbing / releasing means 119 in the first moisture releasing area 2 of the moisture releasing unit 121, and then the radiator 103, further heat is released by heat dissipation from the heat pump 118, and further humidified by moisture release / release means 119 in the second moisture release area 3 of the moisture release unit 121, and then cooled by heat absorption by the heat pump 118 in the heat absorber 105. Next, dehumidification is performed in the moisture absorption section 120 by moisture absorption by the moisture absorption / release means 119, so that the air to be dehumidified 116 supplied to the moisture absorption section 120 and the first moisture release area 2 and the second moisture release area 3 are supplied. The relative humidity difference with the dehumidifying target air 116 can be expanded, and the moisture absorption / release amount of the moisture absorption / release means 119 can be increased with a simple configuration in which the circulation path 111 is not provided. Furthermore, by supplying the dehumidification target air 116 to the radiator 103 and the moisture releasing unit 121 a plurality of times, the air volume suitable for the heat radiation of the heat pump 118 and the moisture absorbing / releasing means 119, and the heat absorption, moisture absorbing / releasing means 119 of the heat pump 118. Eliminating the imbalance with the air volume suitable for moisture absorption, it is possible to perform efficient dehumidification.

  In addition, by configuring the temperature of the dehumidification target air 116 supplied to the first moisture release area 2 to be higher than the temperature of the dehumidification target air 116 supplied to the second moisture release area 3, the first moisture release area 2, the relative humidity of the air to be dehumidified 116 can be lowered to increase the moisture release amount in the first moisture release region 2.

  Moreover, the moisture desorption of the adsorbent 107 can be facilitated by configuring the passage direction of the first moisture release area 2 and the passage direction of the second moisture release area 3 of the air to be dehumidified 116 in the same direction. Thereby, the moisture release amount of the moisture absorption / release means 119 can be increased, and efficient dehumidification can be performed.

  Further, in the moisture absorbing / releasing means 119, the adsorbent 107 carried by the honeycomb rotor 108 adsorbs moisture from the dehumidified air 116 in the moisture absorbing section 120 and desorbs moisture to the dehumidified air 116 in the moisture releasing section 121. The honeycomb rotor 108 is disposed on the honeycomb rotor 108, and the moisture absorption in the moisture absorption section 120 and the moisture desorption in the moisture release section 121 are repeated by the rotation of the honeycomb rotor 108. The moisture adsorption of the adsorbent 107 in the unit 120 and the moisture desorption of the adsorbent 107 in the moisture releasing unit 121 can be easily repeated, and the dehumidifier can be configured at low cost.

  In addition, the adsorbent 107 moves in the order of the hygroscopic portion 120, the first moisture release area 2, and the second moisture release area 3 by the rotation of the honeycomb rotor 108, so that the moisture release in the first moisture release area 2 is achieved. It becomes easier to increase the amount than the moisture release amount in the second moisture release region 3. Thereby, the rotation direction of the honeycomb rotor 108 can be easily adapted to the configuration in which the moisture release amount to the dehumidification target air 116 in the first moisture release region 2 is increased.

  Further, the refrigerant 117 is configured to dissipate heat at a supercritical pressure in the radiator 103, whereby the dehumidification target air 116 is further heated to a high temperature in the radiator 103 and is supplied to the moisture release unit 121. And the relative humidity difference between the dehumidification target air 116 supplied to the moisture absorption unit 120 can be increased. Thereby, the moisture absorption / release amount of the moisture absorption / release means 119 can be increased to perform more efficient dehumidification.

  Further, by using carbon dioxide as the refrigerant 117, the dehumidification target air 116 is further heated to a higher temperature in the radiator 103 and supplied to the dehumidification target air 116 and the moisture absorption unit 120 supplied to the moisture release unit 121. The relative humidity difference with the dehumidification target air 116 can be increased. Thereby, the moisture absorption / release amount of the moisture absorption / release means 119 can be increased to perform more efficient dehumidification.

  The adsorbent 107 supported on the honeycomb rotor 108 of the present embodiment may be a substance that has a hygroscopic property and can be supported on the honeycomb rotor 108 and has a certain degree of heat resistance for moisture desorption. Inorganic adsorption type hygroscopic agents such as silica gel and zeolite, hygroscopic agents such as organic polymer electrolytes (ion exchange resins), and absorbent hygroscopic agents such as lithium chloride can be used. Furthermore, the adsorbent 107 is not limited to one type, and two or more types of the adsorbent 107 described above may be used in combination.

  Moreover, in this embodiment, by supplying the dehumidification target air 116 in the order of the radiator 103, the first moisture release area 2 of the moisture release part 121, the radiator 103, and the second moisture release area 3 of the moisture release part 121, The balance between the air volume suitable for heat dissipation of the heat pump 118 and the moisture absorption and desorption means 119 and the air volume suitable for heat absorption of the heat pump 118 and the moisture absorption and desorption means 119 is adjusted. The frequency | count of supplying the dehumidification object air 116 to the part 121 is not restricted to 2 times, You may supply multiple times, such as 3 times, 4 times, 5 times ... as needed.

  In the present embodiment, the dehumidification target air 116 (a) in which the adsorbent 107 is supplied to the first moisture release region 2 of the moisture release unit 121 and the second moisture release of the moisture release unit 121 by the rotation of the honeycomb rotor 108. The dehumidification target air 116 (b) supplied to the region 3 and the dehumidification target air 116 (c) supplied to the moisture absorption unit 120 are repeatedly contacted in this order. However, the honeycomb rotor 108 is rotated in the reverse direction so that the moisture absorption unit 120 is rotated. Dehumidification target air 116 (c) supplied to the dehumidifying unit 121, the dehumidifying target air 116 (b) supplied to the second dehumidifying region 3 of the moisture releasing unit 121, and the first dehumidifying region 2 of the moisture releasing unit 121. The adsorbent 107 may repeat contact in the order of the dehumidification target air 116 (a). In this case, since the adsorbent 107 that has sufficiently adsorbed moisture at the time of contact with the dehumidification target air 116 (c) in the moisture absorption unit 120 moves to the second moisture release region 3, the adsorption agent is compared with the present embodiment. The amount of moisture desorbed to the dehumidification target air 116 (b) supplied to the second moisture release area 3 of the adsorbent 107 increases, and the dehumidification target air 116 (a) supplied to the first moisture release area 2 of the adsorbent 107 It tends to decrease the amount of moisture desorbed in the water.

Then, by compressing the refrigerant 117 by the compressor 102, the refrigerant 117 circulates in the refrigerant circuit 106 in the order of the radiator 103, the expansion mechanism 104, and the heat absorber 105, and the dehumidification target air 116 supplied to the radiator 103. The heat pump 118 is activated by radiating heat to the heat absorber 105 and absorbing heat from the dehumidification target air 116 supplied to the heat absorber 105.

  FIG. 10 is a diagram showing a detailed configuration of the moisture absorption / release means 119. The moisture absorbing / releasing means 119 includes a cylindrical honeycomb rotor 108 that is capable of ventilating in the axial direction on which the adsorbent 107 is supported, and the honeycomb rotor 108 is rotatably supported by the rotating shaft 4. And the gear 5 is formed in the outer periphery of the honeycomb rotor 108, and the belt 8 is wound around the gear part 7 of the drive motor 6 that rotationally drives the gear 5. Further, the honeycomb rotor 108 is divided into a moisture absorbing part 120, a first moisture releasing area 2 of the moisture releasing part 121, and a second moisture releasing area 3 of the moisture releasing part 121, thereby suppressing mutual circulation of air supplied thereto. So as to partition the air path. When the fan 1 is operated, the dehumidification target air 116 (a) that has passed through the refrigerant outflow side of the radiator 103 in the first moisture release area 2 and the refrigerant inflow side of the radiator 103 has passed through the second moisture release area 3. The dehumidification target air 116 (b) and the dehumidification target air 116 (c) that has passed through the heat absorber 105 are supplied to the hygroscopic unit 120. Here, when the drive motor 6 is driven, the driving force is transmitted to the gear 5 through the belt 8 and the honeycomb rotor 108 rotates, and the adsorbent 107 is supplied to the second moisture release region 3 by this rotation. The contact is repeated in the order of the air 116 (b), the dehumidification target air 116 (a) supplied to the first moisture release region 2, and the dehumidification target air 116 (c) supplied to the moisture absorption unit 120. This adsorbent 107 has a characteristic that it can retain a large amount of moisture if the relative humidity of the exposed air is high, and the amount of water that can be retained decreases when the relative humidity is low. If the contact is repeated, moisture adsorption / desorption is performed according to the difference in the amount of moisture that can be held by the adsorbent 107 at each relative humidity. Here, the dehumidification target air 116 (a) in contact with the adsorbent 107 in the first moisture release area 2 and the dehumidification target air 116 (b) in contact with the adsorbent 107 in the second moisture release area 3 are transmitted in the radiator 103. The air to be dehumidified 116 (c), which is high-temperature and low-relative-humidity air heated by the heat dissipation of the refrigerant 117 and contacts the adsorbent 107 in the hygroscopic section 120, is cooled by the heat absorption of the refrigerant 117 in the heat absorber 105. Since the air has a high relative humidity, the adsorption / desorption action of the adsorbent 107 is performed by the difference in relative humidity between the airs, and the moisture absorption / release means 119 operates. Next, the operation of the dehumidifier will be described.

  FIG. 11 is a Mollier diagram (pressure-enthalpy diagram) showing a change in the state of the refrigerant 117 of the dehumidifier shown in FIG. A cycle in which point A, point B, point C, point D, and point E shown in FIG. 11 are connected by arrows indicates a change in the state of carbon dioxide as the refrigerant 117 circulating in the refrigerant circuit 106. The carbon dioxide refrigerant is compressed to a supercritical pressure higher than the critical pressure in the compressor 102 to change the state from the point A to the point B, and then supplied to the second moisture releasing region 2 on the inflow side of the radiator 103. Although the heat is dissipated with respect to the dehumidification target air 116 (b), since it is in a supercritical state, even if the heat is dissipated, the temperature is lowered without being condensed and the state is changed from point B to point C. Next, heat is dissipated to the dehumidification target air 116 (a) supplied to the first moisture release region 2 on the outflow side of the radiator 103. Similarly, since it is in a supercritical state, it does not condense even if radiated. The temperature drops to a state from point C to point D. When the expansion mechanism 104 expands and depressurizes, the pressure decreases to change the state from point D to point E, and the enthalpy increases by absorbing heat from the dehumidification target air 116 (c) supplied in the heat absorber 105. Then, the state returns from point E to point A. When a refrigerant that radiates heat at a supercritical pressure exemplified by carbon dioxide is used as the working fluid of the heat pump 118, the temperature in the radiator 103 after compression is high. For this reason, since the temperature of the dehumidification target air 116 heated in the radiator 103 is also increased and supplied to the moisture release unit 121 in a lower relative humidity state, the dehumidification target air 116 supplied to the moisture absorption unit 120 The relative humidity difference will increase. By increasing the difference in relative humidity, the moisture absorption / release amount of the moisture absorption / release means 119 is increased, and the dehumidification efficiency is further improved. Further, the supercritical working fluid exemplified by carbon dioxide has a characteristic that a temperature gradient is generated in the process of heat dissipation in the radiator 103. Therefore, the refrigerant 117 has a high temperature on the inflow side of the radiator 103, and gradually decreases in temperature due to heat dissipation, and becomes low on the outflow side of the radiator 103. For this reason, the dehumidification target air 116 (b) heated by the heat dissipation of the refrigerant 117 on the inflow side of the radiator 103 is similarly dehumidified target air 116 (a) heated by the heat dissipation of the refrigerant 117 on the outflow side of the radiator 103. ) In a hot air state. Due to the state change of the refrigerant 117 as described above, the heat pump 118 that absorbs heat in the heat absorber 105 and radiates heat in the radiator 103 operates, and at this time, the enthalpy difference between the points B and D is multiplied by the circulation amount of the refrigerant 117. The value is the amount of heat dissipation in the radiator 103, and the value obtained by multiplying the enthalpy difference between point A and point E (point D) by the circulation amount of the refrigerant 117 is the amount of heat absorption in the heat absorber 105. A value obtained by multiplying the enthalpy difference between B and point A by the circulation amount of the refrigerant 117 is the compression work amount of the compressor 102.

  FIG. 12 is a moist air diagram showing a change in state of the dehumidifying target air 116 in the dehumidifying apparatus shown in FIG. In the wet air diagram shown in FIG. 12, first, the dehumidification target air 116 in the state of point a is supplied to the refrigerant 117 outflow side of the radiator 103 and is heated by the heat radiation of the refrigerant 117 to be in the state of point b. The dehumidification target air 116 in the state of point b is then supplied to the first moisture release region 2 of the moisture release unit 121 to desorb moisture held by the adsorbent 107 carried on the honeycomb rotor 108. As the humidity increases, the temperature decreases and the point c is reached. The dehumidification target air 116 in the state of point c is then supplied to the refrigerant 117 inflow side of the radiator 103 and is heated again by the heat release of the refrigerant 117 to be in the state of point d. The dehumidification target air 116 that has reached the state of point d is supplied to the second moisture release region 3 of the moisture release unit 121 and is further humidified by desorbing the moisture held by the adsorbent 107 again. As the humidity rises, the temperature drops and the point e is reached. The dehumidification target air 116 that has reached the state of point e is then supplied to the heat absorber 105 and is cooled to the dew point temperature or lower by the heat absorption of the refrigerant 117 and becomes saturated at point f. The water saturated at this time is collected in the tank 122 as condensed water. The dehumidification target air 116 that has reached the saturated state at the point f is then supplied to the moisture absorbing unit 120 and dehumidified by adsorbing moisture to the adsorbent 107. As a result, the humidity decreases and the temperature rises. Of dry air. The dehumidifying target air 116 that has reached the point g is sucked into the fan 1 and discharged outside the apparatus. In the state change of the dehumidifying target air 116 described above, the amount of condensed water recovered in the heat absorber 105 is a value obtained by multiplying the absolute humidity difference between the points e and f by the weight-converted air volume of the dehumidifying target air 116, and the hygroscopic part. The moisture absorption amount at 120 is a value obtained by multiplying the absolute humidity difference between the points f and g by the weight-converted air volume of the dehumidifying target air 116. Further, the moisture release amount in the first moisture release region 2 of the moisture release unit 121 is a value obtained by multiplying the absolute humidity difference between the points b and c by the weight-converted air volume of the dehumidification target air 116, and the second release of the moisture release unit 121. The moisture release amount in the moisture release region 3 is a value obtained by multiplying the absolute humidity difference between the points d and e by the weight-converted air volume of the dehumidification target air 116. Here, the air at the point d indicating the inlet air state of the second moisture release region 3 is heated to a higher temperature than the air at the point b indicating the inlet air state of the first moisture release region 2, and therefore the second moisture release region 3. The moisture release amount tends to increase with respect to the moisture release amount in the first moisture release region 2.

  In the above operation, in the ideal state, the point e indicating the outlet air state of the moisture releasing unit 121 approaches the point e ′ having the same relative humidity as the point f indicating the inlet air state of the moisture absorbing unit 120, and the moisture absorbing unit 120. The point g that indicates the outlet air state of the gas approaches the point g ′ that has the same relative humidity as the point d that indicates the inlet air state of the moisture release unit 121. Therefore, the relative humidity at the point f is increased and the relative humidity at the point d is decreased, that is, the supply air to the moisture absorption unit 120 indicated by the point f and the supply air to the moisture release unit 121 indicated by the point d. Enlarging the relative humidity difference increases the amount of moisture absorbed and released, resulting in improved dehumidification efficiency. Further, an added value of a value obtained by multiplying the enthalpy difference between the points a and b by the weight-converted air volume of the dehumidified air 116 and a value obtained by multiplying the enthalpy difference between the points c and d and the weight-converted air volume of the dehumidified air 116 is obtained. A value obtained by multiplying the heat dissipation amount in the radiator 103 and the enthalpy difference between the points e and f by the weight-converted air volume of the air to be dehumidified 116 becomes the heat absorption amount in the heat absorber 105, and the heat dissipation amount in the heat radiator 103 and the heat absorption amount in the heat absorber 105. The amount of heat is equal to the amount of heat release and the amount of heat absorption obtained from the state change of the refrigerant 117 in FIG. Therefore, the heat release amount of the heat pump 118 and the moisture release amount of the moisture absorption / desorption means 119, which are insufficient for one supply of the dehumidification target air 116 in the radiator 103 and the moisture release unit 121, are supplied to the dehumidification target air via the radiator 103. 116 is supplied to the first moisture release area 2 and then supplied again to the second moisture release area 3 via the radiator 103 to supplement the heat absorption in the heat absorber 105 and the moisture absorption in the moisture absorber 120. The air volume of the dehumidifying target air 116 can be set to an optimum value.

  As described above, with the configuration and operation described above, the dehumidifier of this embodiment has the following effects.

  The air to be dehumidified 116 is heated by the heat dissipation of the heat pump 118 in the radiator 103, then humidified by the moisture absorption / release means 119 in the moisture release unit 121, and then cooled by the heat absorption of the heat pump 118 in the heat absorber 105. Next, by dehumidifying the moisture absorbing section 120 by absorbing moisture by the moisture absorbing / releasing means 119, the relative humidity difference between the dehumidifying target air 116 supplied to the moisture absorbing section 120 and the dehumidifying target air 116 supplied to the moisture releasing section 121 is determined. The moisture absorption / release amount of the moisture absorption / release means 119 can be increased with a simple configuration that does not provide the circulation path 111. Furthermore, by supplying more air than the dehumidification target air 116 supplied to the heat absorber 105 to the moisture release unit 121, an air volume suitable for moisture release of the moisture absorption / release means 119 and an air volume suitable for heat absorption of the heat pump 118 Can be eliminated and efficient dehumidification can be performed.

  In addition, the air to be dehumidified 116 is heated by the heat dissipation of the heat pump 118 in the radiator 103, and then humidified by the moisture absorbing / releasing means 119 in the moisture releasing section 121, and then in the heat absorber 105 by the heat absorption of the heat pump 118. Relative humidity between the dehumidification target air 116 supplied to the moisture absorption unit 120 and the dehumidification target air 116 supplied to the moisture release unit 121 by cooling and then dehumidifying the moisture absorption unit 120 by absorbing moisture by the moisture absorption / release unit 119. The difference can be enlarged, and the moisture absorption / release amount of the moisture absorption / release means 119 can be increased with a simple configuration in which the circulation path 111 is not provided. Further, by supplying more air than the dehumidification target air 116 supplied to the moisture absorption unit 120 to the moisture release unit 121, the air volume suitable for moisture release by the moisture absorption / release unit 119 and the moisture absorption by the moisture absorption / release unit 119 are improved. Eliminates imbalance with the appropriate air volume and can perform efficient dehumidification.

  In addition, the air to be dehumidified 116 is heated in the radiator 103 by the heat radiation of the heat pump 118, then humidified by the moisture absorbing / releasing means 119 in the first moisture releasing area 2 of the moisture releasing unit 121, and then the radiator 103, further heat is released by heat dissipation from the heat pump 118, and further humidified by moisture release / release means 119 in the second moisture release area 3 of the moisture release unit 121, and then cooled by heat absorption by the heat pump 118 in the heat absorber 105. Next, dehumidification is performed in the moisture absorption section 120 by moisture absorption by the moisture absorption / release means 119, so that the air to be dehumidified 116 supplied to the moisture absorption section 120 and the first moisture release area 2 and the second moisture release area 3 are supplied. The relative humidity difference with the dehumidifying target air 116 can be expanded, and the moisture absorption / release amount of the moisture absorption / release means 119 can be increased with a simple configuration in which the circulation path 111 is not provided. Furthermore, by supplying the dehumidification target air 116 to the radiator 103 and the moisture releasing unit 121 a plurality of times, the air volume suitable for the heat radiation of the heat pump 118 and the moisture absorbing / releasing means 119, and the heat absorption, moisture absorbing / releasing means 119 of the heat pump 118. Eliminating the imbalance with the air volume suitable for moisture absorption, it is possible to perform efficient dehumidification.

  Further, by configuring the temperature of the dehumidification target air 116 supplied to the second moisture release area 3 to be higher than the temperature of the dehumidification target air 116 supplied to the first moisture release area 2, the second moisture release area The relative humidity of the air to be dehumidified 116 supplied to 3 can be lowered to increase the amount of moisture release in the second moisture release region 3.

  Moreover, the moisture desorption of the adsorbent 107 can be facilitated by configuring the passage direction of the first moisture release area 2 and the passage direction of the second moisture release area 3 of the air to be dehumidified 116 in the same direction. Thereby, the moisture release amount of the moisture absorption / release means 119 can be increased, and efficient dehumidification can be performed.

  Further, in the moisture absorbing / releasing means 119, the adsorbent 107 carried by the honeycomb rotor 108 adsorbs moisture from the dehumidified air 116 in the moisture absorbing section 120 and desorbs moisture to the dehumidified air 116 in the moisture releasing section 121. The honeycomb rotor 108 is disposed on the honeycomb rotor 108, and the moisture absorption in the moisture absorption section 120 and the moisture desorption in the moisture release section 121 are repeated by the rotation of the honeycomb rotor 108. The moisture adsorption of the adsorbent 107 in the unit 120 and the moisture desorption of the adsorbent 107 in the moisture releasing unit 121 can be easily repeated, and the dehumidifier can be configured at low cost.

  Further, by the configuration in which the adsorbent 107 moves in the order of the moisture absorbing portion 120, the second moisture release region 3, and the first moisture release region 2 by the rotation of the honeycomb rotor 108, moisture release in the second moisture release region 3 is achieved. It becomes easier to increase the amount than the moisture release amount in the first moisture release region 2. Thereby, the rotation direction of the honeycomb rotor 108 can be easily adapted to the configuration in which the moisture release amount to the dehumidification target air 116 in the second moisture release region 3 is increased.

  Further, the refrigerant 117 is configured to dissipate heat at a supercritical pressure in the radiator 103, whereby the dehumidification target air 116 is further heated to a high temperature in the radiator 103 and is supplied to the moisture release unit 121. And the relative humidity difference between the dehumidification target air 116 supplied to the moisture absorption unit 120 can be increased. Thereby, the moisture absorption / release amount of the moisture absorption / release means 119 can be increased to perform more efficient dehumidification.

  Further, by using carbon dioxide as the refrigerant 117, the dehumidification target air 116 is further heated to a higher temperature in the radiator 103 and supplied to the dehumidification target air 116 and the moisture absorption unit 120 supplied to the moisture release unit 121. The relative humidity difference with the dehumidification target air 116 can be increased. Thereby, the moisture absorption / release amount of the moisture absorption / release means 119 can be increased to perform more efficient dehumidification.

  The adsorbent 107 supported on the honeycomb rotor 108 of the present embodiment may be a substance that has a hygroscopic property and can be supported on the honeycomb rotor 108 and has a certain degree of heat resistance for moisture desorption. Inorganic adsorption type hygroscopic agents such as silica gel and zeolite, hygroscopic agents such as organic polymer electrolytes (ion exchange resins), and absorbent hygroscopic agents such as lithium chloride can be used. Furthermore, the adsorbent 107 is not limited to one type, and two or more types of the adsorbent 107 described above may be used in combination.

  Moreover, in this embodiment, by supplying the dehumidification target air 116 in the order of the radiator 103, the first moisture release area 2 of the moisture release part 121, the radiator 103, and the second moisture release area 3 of the moisture release part 121, The balance between the air volume suitable for heat dissipation of the heat pump 118 and the moisture absorption and desorption means 119 and the air volume suitable for heat absorption of the heat pump 118 and the moisture absorption and desorption means 119 is adjusted. The frequency | count of supplying the dehumidification object air 116 to the part 121 is not restricted to 2 times, You may supply multiple times, such as 3 times, 4 times, 5 times ... as needed.

  In the present embodiment, the dehumidification target air 116 (b) in which the adsorbent 107 is supplied to the second moisture release area 3 of the moisture release unit 121 and the first moisture release of the moisture release unit 121 by the rotation of the honeycomb rotor 108. The dehumidification target air 116 (a) supplied to the region 2 and the dehumidification target air 116 (c) supplied to the moisture absorption unit 120 are repeatedly contacted in this order. However, the honeycomb rotor 108 is rotated in the reverse direction, and the moisture absorption unit 120 is rotated. Dehumidification target air 116 (c) supplied to the dehumidifying unit 121, the dehumidifying target air 116 (a) supplied to the first dehumidifying region 2 of the moisture releasing unit 121, and the second dehumidifying region 3 of the moisture releasing unit 121. The adsorbent 107 may repeat contact in the order of the dehumidification target air 116 (b). In this case, since the adsorbent 107 that has sufficiently adsorbed moisture at the time of contact with the dehumidification target air 116 (c) in the moisture absorption unit 120 moves to the first moisture release region 2, the adsorbent 107 is adsorbed to the present embodiment. The amount of moisture desorbed to the dehumidification target air 116 (a) supplied to the first moisture release region 2 of the adsorbent 107 increases, and the dehumidification target air 116 (b) supplied to the second moisture release region 3 of the adsorbent 107 There is a tendency for the amount of moisture desorbed to decrease.

  As described above, the dehumidifying apparatus according to the present invention can perform efficient dehumidification in various environments with a simple configuration that does not require the circulation path 111, and includes a dehumidifier, a dryer, an air conditioner, and solvent recovery. Suitable for applications where a highly efficient dehumidifying function is desired, such as devices.
