  However, in the conventional air conditioner, the air whose temperature has been increased by being dehumidified by the desiccant rotor is supplied to the air-conditioned space through heat exchange with the outside air flowing through the second ventilation path. For this reason, for example, when the outside air temperature becomes high, such as during the daytime in summer, there is a problem that the air whose temperature has increased is supplied to the air-conditioned space without being sufficiently cooled, and the air-conditioning load increases.

  The present invention has been made in view of the above problems, and an object thereof is to provide an air conditioner that can cool dehumidified air and supply it to an air-conditioned space regardless of the temperature conditions of the outside air. There is.

Heat is exchanged with the air flowing through the air, and the air is cooled and supplied to the air-conditioned space, and the air flowing through the second ventilation path heat-exchanged with the air flowing through the first ventilation path by the heat exchanger is heated by the heat source. Thus, the moisture adsorbed on the first moisture absorbing member is in the air flowing through the second ventilation path. In the air conditioner configured to release, in the air flowing through the third ventilation path, a third ventilation path at least partially arranged in parallel with the upstream side of the heat exchanger of the second ventilation path. A second moisture absorbing member that adsorbs the moisture and releases the moisture into the air flowing upstream of the heat exchanger in the second ventilation path.

  As a result, moisture adsorbed from the air flowing through the third ventilation path by the second moisture absorbing member is evaporated and released into the air flowing through the second ventilation path, and thus flows through the second ventilation path. The air to be cooled is cooled by the heat of evaporation of moisture.

  In addition, the first ventilation path that circulates air in the air-conditioned space, the second ventilation path that circulates outside air, and the moisture in the air that circulates through the first ventilation path are adsorbed to circulate through the second ventilation path.

A heat source for heating air, dehumidifying the air flowing through the first ventilation path by the first hygroscopic member, and exchanging heat of the dehumidified air with the air flowing through the second ventilation path by a heat exchanger The air is supplied to the air-conditioned space after being cooled by the heat exchanger, and the air flowing through the second ventilation path that is heat-exchanged with the air flowing through the first ventilation path by the heat exchanger is heated by the heat source. Air conditioning that releases the adsorbed moisture into the air flowing through the second ventilation path The evaporator for cooling the air flowing downstream of the heat exchanger of the first ventilation path and the heat source for heating the air flowing downstream of the heat exchanger of the second ventilation path. A condenser, a refrigerant circuit that circulates the refrigerant to the evaporator and the condenser by a compressor, and moisture in the air flowing through the first ventilation path cooled by the evaporator to adsorb moisture in the second ventilation path And a second moisture absorbing member that is released into the air that circulates upstream of the exchanger.

  Thereby, the moisture adsorbed from the air flowing through the first ventilation path by the second moisture absorbing member is evaporated and released into the air flowing through the second ventilation path, and thus flows through the second ventilation path. The air to be cooled is cooled by the heat of evaporation of moisture.

  In addition, the first ventilation path that circulates air in the air-conditioned space, the second and third ventilation paths that circulate outside air, and the moisture in the air that circulates through the first ventilation path are adsorbed to the third ventilation path. A first moisture-absorbing member that is released into the air flowing through the ventilation path, a heat exchanger that exchanges heat between the air flowing through the first ventilation path and the air flowing through the second ventilation path, and a third ventilation A heat source for heating the air flowing through the path, the air flowing through the first ventilation path is dehumidified by the first hygroscopic member, and the dehumidified air is circulated through the second ventilation path by the heat exchanger; Air that is cooled by heat exchange, supplied to the air-conditioned space, and the air that flows through the third ventilation path is heated by a heat source, so that the moisture adsorbed on the first moisture absorbing member flows through the third ventilation path. In the air conditioner which is discharged into the inside, heat exchange of the second ventilation path A fourth ventilation path at least part of which is arranged in parallel with the upstream side of the air flow, and the moisture in the air flowing through the fourth ventilation path is adsorbed and circulated through the upstream side of the heat exchanger of the second ventilation path And a second moisture absorbing member that is released into the air.

  As a result, moisture adsorbed from the air flowing through the fourth ventilation path by the second moisture absorbing member is evaporated and released into the air flowing through the second ventilation path, and thus flows through the second ventilation path. The air to be cooled is cooled by the heat of evaporation of moisture.

  According to the present invention, the temperature of the air flowing through the second ventilation path can be reduced by the heat of evaporation of the moisture released from the second moisture absorbing member, so that the outside air, for example, during summer daytime becomes high temperature. Even in this case, the air flowing through the first ventilation path whose temperature has been increased by being dehumidified by the first moisture absorbing member can be reliably cooled by the heat exchanger.

  The apparatus main body 11 includes a first ventilation path 11a, a second ventilation path 11b, and a third ventilation path 11c provided by partitioning the interior of the apparatus main body 11, and the first ventilation path 11a and the second ventilation path 11b. And the opening part to which a duct is each connected is provided in the both ends of the 3rd ventilation path 11c. Further, both ends of the first ventilation path 11a communicate with the conditioned space A, both ends of the second ventilation path 11b communicate with the outside, and both ends of the third ventilation path 11c are within the conditioned space B. To communicate with each other.

  The 1st air blower 12 is installed in the 1st ventilation path 11a, and it distribute | circulates air from the one end side of the 1st ventilation path 11a toward the other end side so that the air of the air-conditioned space A circulates. It has become.

  The 2nd air blower 13 is installed in the 2nd ventilation path 11b, and distribute | circulates external air to the 2nd ventilation path 11b in the opposite direction to the flow direction of the air of the 1st ventilation path 11a. Yes.

  The 3rd air blower 14 is installed in the 3rd ventilation path 11c, and distribute | circulates the air of the air-conditioned space B to the 3rd ventilation path 11c in the direction opposite to the air flow direction of the 2nd ventilation path 11b. It has become.

  The first desiccant rotor 15 is composed of a member in which an element 15a containing a hygroscopic agent such as silica gel or zeolite is formed in a disk shape, and is connected to the upstream side of the sensible heat exchanger 16 and the second side of the first ventilation path 11a. It is provided over the downstream side of the heat exchanger of the ventilation path 11b. In addition, the first desiccant rotor 15 rotates the element 15a around the radial center by a motor (not shown) so that the element 15a rotates between the first ventilation path 11a and the second ventilation path 11b. While moving.

  The sensible heat exchanger 16 is a well-known cross-flow type heat exchanger that exchanges only sensible heat between the air flowing through the first ventilation path 11a and the air flowing through the second ventilation path 11b. It has become.

  Similar to the first desiccant rotor 15, the second desiccant rotor 17 is made of a member in which an element 17a containing a hygroscopic agent is formed in a disk shape, and is upstream of the sensible heat exchanger 16 in the second ventilation path 11b. Are provided across the second ventilation path 11b and the third ventilation path 11c. Further, the second desiccant rotor 17 rotates the element 17a between the second ventilation path 11b and the third ventilation path 11c by rotating the element 17a about the radial center by a motor (not shown). While moving.

  The heat source 18 includes a condenser of a cooling device and an electric heater, and is disposed between the first desiccant rotor 15 and the sensible heat exchanger 16 in the second ventilation path 11b.

  In the air conditioner configured as described above, first, the first blower 12, the second blower 13, the third blower 14, the first desiccant rotor 15, the second desiccant rotor 17, and the heat source 18 are operated. To do. Thereby, in the 1st ventilation path 11a, the return air (RA) distribute | circulated from the air-conditioning space A by the 1st air blower 12 is made to contact the element 15a of the 1st desiccant rotor 15, and the water | moisture content contained in air is made. Adsorbed to the element 15a. The air whose absolute humidity has been reduced by the first desiccant rotor 15 is heat-exchanged with the air flowing through the second ventilation path 11b by the sensible heat exchanger 16, and supplied to the conditioned space A as supply air (SA). Moreover, in the 2nd ventilation path 11b, the external air (OA) distribute | circulated from the outside with the 2nd air blower 13 is made to contact the element 17a of the 2nd desiccant rotor 17, and the water | moisture content adsorb | sucking to the element 17a is made. It discharge | releases in the air which distribute | circulates the 2nd ventilation path 11b. The air whose absolute humidity has been increased by the second desiccant rotor 17 is heat-exchanged with the air flowing through the first ventilation path 11 a by the sensible heat exchanger 16, and then the air is heated by the heat source 18. By bringing the air heated by the heat source 18 into contact with the element 15a of the first desiccant rotor 15, the moisture adsorbed on the element 15a is evaporated and released into the air, and the air that has absorbed the moisture is exhausted (EA ) To the outside. Further, in the third ventilation path 11c, the return air (RA) circulated from the air-conditioned space B by the third blower 14 is brought into contact with the element 17a of the second desiccant rotor 17 so that moisture contained in the air is contained in the element. The air whose absolute humidity is reduced in the second desiccant rotor 17 is supplied into the conditioned space B as supply air (SA).

  When moisture is adsorbed to the first desiccant rotor 15 in the first ventilation path 11a, the temperature of the air flowing through the first ventilation path 11a rises due to the heat of condensation of moisture. Further, when moisture is released from the second desiccant rotor 17 in the second ventilation path 11b, the temperature of the air flowing through the second ventilation path 11b decreases due to the evaporation heat of moisture. The air flowing through the first ventilation path 11 a is cooled and supplied to the air-conditioned space A by exchanging heat of these air with the sensible heat exchanger 16. Further, the cooled air in the air-conditioned space B flowing through the third ventilation path 11c has a high relative humidity, and the moisture in the air is efficiently adsorbed to the element 17a of the second desiccant rotor 17.

  The air state at this time will be described with reference to the air diagram of FIG. 2. The return air (RA) flowing into the first ventilation path 11a from the air-conditioned space A (state A) is caused by the first desiccant rotor 15. Dehumidification reduces the absolute humidity and increases the temperature due to the heat of condensation of moisture in the air (state B). Further, outside air (OA) flowing into the second ventilation path 11b from the outside (state D) is humidified by the second desiccant rotor 17 that has adsorbed moisture in the air flowing through the third ventilation path 11c. As a result, the absolute humidity increases and the temperature decreases due to the heat of evaporation of water (state D '). Further, the return air (RA) flowing into the third ventilation path 11c from the air-conditioned space B (state H) is dehumidified by the second desiccant rotor 17 to reduce the absolute humidity, and the moisture in the air The temperature rises due to the heat of condensation (state I). The air in the state B flowing through the first ventilation path 11a and the air in the state D ′ flowing through the second ventilation path 11b are heat-exchanged by the sensible heat exchanger 16, thereby flowing through the first ventilation path 11a. The air to be cooled is cooled (state C ′), and the air flowing through the second ventilation path 11b is heated (state E ′). In this way, the air in the state C ′ flowing through the first ventilation path 11a is sufficiently cooled and supplied to the conditioned space A as supply air (SA). Further, the air in the state E ′ flowing through the second ventilation path 11b is heated by the heat source 18 (state F ′), and the first desiccant rotor 15 that has adsorbed moisture in the air flowing through the first ventilation path 11a. As a result of the humidification, the absolute humidity rises, and the temperature is lowered by the heat of evaporation of the water, and is discharged to the outside as exhaust (EA) (state G ′).

  Thus, according to the air conditioning apparatus of the present embodiment, the sensible heat exchanger 16 performs the second heat exchange before the air flowing through the first ventilation path 11a and the air flowing through the second ventilation path 11b. Since the desiccant rotor 17 releases moisture to the air flowing through the second ventilation path 11b, the second desiccant rotor 17 causes the second ventilation to pass even when the outside air becomes hot, such as during the daytime in summer. The temperature of the air flowing through the passage 11b can be lowered, and the air flowing through the first ventilation passage 11a whose temperature has been increased by being dehumidified by the first desiccant rotor 15 is reliably ensured by the sensible heat exchanger 16. Can be cooled.

  Further, since the air in the air-conditioned space B is circulated through the third ventilation path 11c so that moisture is adsorbed by the second desiccant rotor 17, the air that has been cooled and has a high relative humidity is second desiccant. The element can be brought into contact with the element 17a of the rotor 17, and moisture in the air can be efficiently adsorbed to the element 17a.

  FIG. 3 shows a second embodiment of the present invention and is a schematic view of an air conditioner. The same components as those in the first embodiment are denoted by the same reference numerals.

  The air conditioning apparatus according to the present embodiment circulates through the apparatus main body 21 provided with the fourth ventilation path 21d, the fourth blower 22 that circulates air through the fourth ventilation path 21d, and the second ventilation path 21b. A third desiccant rotor 23 that adsorbs moisture from the air to be heated, and a heat source 24 that heats the air flowing through the fourth ventilation path 21d.

  The apparatus main body 21 is provided on the downstream side of the sensible heat exchanger 16 of the second ventilation path 21b so that a part of the fourth ventilation path 21d is adjacent to each other, and one end side and the other end side of the fourth ventilation path 21d are Each communicates with the outside.

  The 4th air blower 22 is installed in the 4th ventilation path 21d, and the flow direction of the air which distribute | circulates the air in the 4th ventilation path 21d adjacent to the 2nd ventilation path 21b through the 2nd ventilation path 21b. It is designed to circulate in the opposite direction.

  The 3rd desiccant rotor 23 is provided over the 2nd ventilation path 21b and the 4th ventilation path 21d between the 1st desiccant rotor 15 and the sensible heat exchanger 16 of the 2nd ventilation path 21b. Yes.

  The heat source 24 is disposed on the upstream side of the third desiccant rotor 23 in the fourth ventilation path 21d, and heats the air flowing through the fourth ventilation path 21d.

  In the air conditioner configured as described above, first, the first blower 12, the second blower 13, the third blower 14, the heat source 18, the fourth blower 22, the first desiccant rotor 15, the second The desiccant rotor 17, the third desiccant rotor 23, and the heat source 24 are operated. Thereby, in the 1st ventilation path 21a, the return air (RA) distribute | circulated from the air-conditioning space A by the 1st air blower 12 is made to contact the element 15a of the 1st desiccant rotor 15, and the water | moisture content contained in air is made. Adsorbed to the element 15a. The air whose absolute humidity has been reduced by the first desiccant rotor 15 is heat-exchanged with the air flowing through the second ventilation path 21b by the sensible heat exchanger 16, and supplied to the conditioned space A as supply air (SA). Further, in the second ventilation path 21b, the outside air (OA) circulated from the outside by the second blower 13 is brought into contact with the element 17a of the second desiccant rotor 17, whereby moisture adsorbed on the element 17a is absorbed. It discharge | releases in the air which distribute | circulates the 2nd ventilation path 21b. After the air whose absolute humidity has been increased by the second desiccant rotor 17 is heat-exchanged with the air flowing through the first ventilation path 21a by the sensible heat exchanger 16, the air is exchanged with the element 23a of the third desiccant rotor 23. The moisture contained in the air is adsorbed to the element 23a. The air whose absolute humidity has been lowered by the third desiccant rotor 23 is heated by the heat source 18 and brought into contact with the element 15a of the first desiccant rotor 15, thereby evaporating the moisture adsorbed on the element 15a and releasing it into the air. The air that has absorbed moisture is discharged to the outside as exhaust (EA). Further, in the third ventilation path 21c, the return air (RA) circulated from the air-conditioned space B by the third blower 14 is brought into contact with the element 17a of the second desiccant rotor 17 so that moisture contained in the air is contained in the element. Air that has been adsorbed by 17a and has reduced absolute humidity is supplied into the conditioned space B as supply air (SA). Further, in the fourth ventilation path 21d, the outside air (OA) circulated from the outside by the fourth blower 22 is heated by the heat source 24, and the heated air is brought into contact with the element 23a of the third desiccant rotor 23. Thus, the moisture adsorbed on the element 23a evaporates and is released into the air, and the air that has absorbed the moisture is discharged to the outside as exhaust (EA).

  When moisture is adsorbed to the first desiccant rotor 15 in the first ventilation path 21a, the temperature of the air flowing through the first ventilation path 21a rises due to condensation heat of moisture. Further, when moisture is released from the second desiccant rotor 17 in the second ventilation path 21b, the temperature of the air flowing through the second ventilation path 21b decreases due to the evaporation heat of moisture. The air flowing through the first ventilation path 21 a is cooled and supplied to the air-conditioned space A by exchanging heat of these air with the sensible heat exchanger 16. Further, the cooled air in the air-conditioned space B flowing through the third ventilation path 11c has a high relative humidity, and the moisture in the air is efficiently adsorbed to the element 17a of the second desiccant rotor 17.

  Thus, according to the air conditioning apparatus of the present embodiment, as in the first embodiment, the air flows through the first ventilation path 21a whose temperature has been increased by being dehumidified by the first desiccant rotor 15. Air can be reliably cooled by the sensible heat exchanger 16.

  Further, since the air discharged from the sensible heat exchanger 16 in the second ventilation path 21b is dehumidified by the third desiccant rotor 23, the air having a low absolute humidity contacts the element 15a of the first desiccant rotor 15. Thus, the moisture adsorbed on the first desiccant rotor 15 can be surely released, and the dehumidifying ability of the first desiccant rotor 15 can be improved.

  FIG. 4 shows a third embodiment of the present invention and is a schematic view of an air conditioner. The same components as those in the first embodiment are denoted by the same reference numerals.

  The air conditioner of the present embodiment is configured such that the downstream side of the first ventilation path 31a of the apparatus main body 31 and the upstream side of the second ventilation path 31b are adjacent to each other, and the second desiccant rotor 17 is the first ventilation path. It is provided over the path 31a and the second ventilation path 31b. The air conditioner also includes a refrigerant circuit 40 that cools the air supplied to the air-conditioned space A, and an evaporator 41 provided on the upstream side of the second desiccant rotor 17 in the first ventilation path 31a and a second The refrigerant discharged from the compressor 43 circulates in a condenser 42 as a heat source provided on the upstream side of the first desiccant rotor 15 in the ventilation path 31b. Further, a third ventilation path 31 c communicating with the air-conditioned space A is provided between the sensible heat exchanger 16 and the evaporator 41 in the first ventilation path 31 a, and the return air (RA) is returned by the first blower 12. Inflow.

  In the air conditioner configured as described above, first, the first blower 12, the second blower 13, the first desiccant rotor 15, the second desiccant rotor 17, and the compressor 43 are operated. Thereby, in the 1st ventilation path 31a, the return air (RA) distribute | circulated from the air-conditioning space A by the 1st air blower 12 is made to contact the element 15a of the 1st desiccant rotor 15, and the water | moisture content contained in air is made. Adsorbed to the element 15a. The air whose absolute humidity has been reduced by the first desiccant rotor 15 is heat-exchanged with the air flowing through the second ventilation path 31b by the sensible heat exchanger 16, and then flows into the air and the third ventilation path 31c. Combine the return air (RA). Included in the air by cooling the air flowing through the second ventilation path 31b merged with the air flowing through the third ventilation path 31c by the evaporator 41 and bringing it into contact with the element 17a of the second desiccant rotor 17 Moisture is adsorbed by the element 17a and supplied to the conditioned space A as supply air (SA). Moreover, in the 2nd ventilation path 31b, the external air (OA) distribute | circulated from the outside with the 2nd air blower 13 is made to contact the element 17a of the 2nd desiccant rotor 17, and the water | moisture content adsorb | sucking to the element 17a is made. It discharge | releases in the air which distribute | circulates the 2nd ventilation path 31b. After the air whose absolute humidity has been increased by the second desiccant rotor 17 is heat-exchanged with the air flowing through the first ventilation path 31 a by the sensible heat exchanger 16, the air is heated by the condenser 42. By bringing the air heated by the condenser 42 into contact with the element 15a of the first desiccant rotor 15, the moisture adsorbed on the element 15a is evaporated and released into the air, and the air that has absorbed the moisture is exhausted ( Discharge to the outside as EA).

  When moisture is adsorbed to the first desiccant rotor 15 in the first ventilation path 31a, the temperature of the air flowing through the first ventilation path 31a rises due to the heat of condensation of moisture. Further, when moisture is released from the second desiccant rotor 17 in the second ventilation path 31b, the temperature of the air flowing through the second ventilation path 31b decreases due to the evaporation heat of moisture. The air flowing through the first ventilation path 31 a is cooled and supplied to the air-conditioned space A by exchanging heat of these air with the sensible heat exchanger 16. In addition, the air flowing through the first ventilation path 31a is cooled by the evaporator 41, so that the relative humidity becomes high, and the moisture in the air is efficiently adsorbed to the element 17a of the second desiccant rotor 17.

  Thus, according to the air conditioning apparatus of the present embodiment, as in the first embodiment, the air flows through the first ventilation path 31a whose temperature has been increased by being dehumidified by the first desiccant rotor 15. Air can be reliably cooled by the sensible heat exchanger 16.

  In addition, since the air cooled by the evaporator 41 disposed on the upstream side of the second desiccant rotor 17 in the first ventilation path 31a is circulated through the second desiccant rotor 17 to absorb moisture, Air that has been cooled and has a high relative humidity can be brought into contact with the element 17a of the second desiccant rotor 17, and moisture in the air can be efficiently adsorbed onto the element 17a.

  Moreover, since the air which distribute | circulates the 1st ventilation path 31a is dehumidified by the 1st and 2nd desiccant rotors 15 and 17, the air supplied to the air-conditioned space A can be dehumidified more reliably.

  Further, the air flowing through the first ventilation path 31a is cooled, and the heat absorbed by the evaporator 41 is released in the condenser 42 disposed on the upstream side of the first desiccant rotor 15 in the second ventilation path 31b. Since it did in this way, the 1st desiccant rotor 15 can be reproduced | regenerated with the condensation heat of the condenser 42, and it is not necessary to provide a heat source separately.

  Further, since the air in the air-conditioned space A is caused to flow between the sensible heat exchanger 16 and the evaporator 41 in the first ventilation path 31a by the third ventilation path 31c, the second desiccant rotor 17 is supplied with the second The air in the air-conditioned space A that has not been dehumidified by the first desiccant rotor 15 can be circulated, and the amount of moisture adsorbed by the second desiccant rotor 17 can be increased.

  In the third embodiment, the third ventilation path 31c is provided between the sensible heat exchanger 16 and the evaporator 41 of the first ventilation path 31a so that the return air in the air-conditioned space A is circulated. As shown in FIG. 5, the air flowing through the first ventilation path 31 a is cooled by the evaporator 41 without causing the air in the air-conditioned space A to flow into the second desiccant rotor 17. You may make it adsorb | suck a water | moisture content. In this case, it is possible to dehumidify the air flowing through the first ventilation path 31a more reliably.

  FIG. 6 shows a fourth embodiment of the present invention and is a schematic view of an air conditioner.

  The apparatus main body 51 of the air conditioner includes a first ventilation path 51a that circulates air in the air-conditioned space A, and a second ventilation path 51b that circulates outside air that exchanges heat with the air that circulates through the first ventilation path 51a. And at least a part of the third ventilation path 51c that is disposed adjacent to the upstream side of the first ventilation path 51a and circulates the outside air, and at least a part of the upstream side of the second ventilation path 51b. And a fourth ventilation path 51d through which the air in the air-conditioned space B is circulated.

  Moreover, this air conditioning apparatus is the same as the said embodiment, the 1st air blower 52 which distribute | circulates the air of the air-conditioning space A to the 1st ventilation path 51a, and the 2nd to distribute | circulate external air to the 2nd ventilation path 51b. A blower 53, a third blower 54 that circulates outside air through the third ventilation path 51c, a fourth blower 55 that circulates air in the air-conditioned space B through the fourth ventilation path 51d, and a first ventilation path A first desiccant rotor 56 as a first moisture absorbing member that adsorbs moisture in the air flowing through 51a and releases it into the air flowing through the third ventilation path 51c, and flows through the first ventilation path 51a. The sensible heat exchanger 57 as a heat exchanger that exchanges heat between the air and the air flowing through the second ventilation path 51b, and the second ventilation by adsorbing moisture in the air flowing through the fourth ventilation path 51d A second moisture absorbing member that is released into the air flowing through the passage 51b; A second desiccant rotor 58 of Te, and a heat source 59 for heating the air flowing through the third air passage 51c.

  In the air conditioner configured as described above, first, the first blower 52, the second blower 53, the third blower 54, the fourth blower 55, the first desiccant rotor 56, and the second desiccant rotor. Drive 58. Thereby, in the 1st ventilation path 51a, the return air (RA) distribute | circulated from the air-conditioning space A by the 1st air blower 52 is made to contact the element 56a of the 1st desiccant rotor 56, and the water | moisture content contained in air is made. Adsorbed to the element 56a. The air whose absolute humidity has been reduced by the first desiccant rotor 56 is heat-exchanged with the air flowing through the second ventilation path 51b by the sensible heat exchanger 57, and supplied to the conditioned space A as supply air (SA). Further, in the second ventilation path 51b, the outside air (OA) circulated from the outside by the second blower 53 is brought into contact with the element 58a of the second desiccant rotor 58, whereby moisture adsorbed on the element 58a is absorbed. It discharge | releases in the air which distribute | circulates the 2nd ventilation path 51b. The air whose absolute humidity has been increased by the second desiccant rotor 58 is subjected to heat exchange with the air flowing through the first ventilation path 51a by the sensible heat exchanger 57, and then discharged to the outside as exhaust (EA). In the third ventilation path 51c, the outside air (OA) circulated from the outside by the third blower 54 is heated by the heat source 59 and brought into contact with the element 56a of the first desiccant rotor 56. The adsorbed moisture is evaporated and released into the air, and the air that has absorbed the moisture is discharged to the outside as exhaust (EA). Further, in the fourth ventilation path 51d, the return air (RA) circulated from the air-conditioned space B by the fourth blower 55 is brought into contact with the element 58a of the second desiccant rotor 58 to remove moisture contained in the air. Air that has been adsorbed by 58a and has reduced absolute humidity is supplied into the conditioned space B as supply air (SA).

  When moisture is adsorbed to the first desiccant rotor 56 in the first ventilation path 51a, the temperature of the air flowing through the first ventilation path 51a rises due to condensation heat of moisture. Further, when moisture is released from the second desiccant rotor 58 in the second ventilation path 51b, the temperature of the air flowing through the second ventilation path 51b decreases due to the evaporation heat of moisture. The air flowing through the first ventilation path 51 a is cooled and supplied to the air-conditioned space A by exchanging heat of these air with the sensible heat exchanger 57. The air flowing through the second ventilation path 51b humidified by the second desiccant rotor 58 is discharged to the outside, and moisture adsorbed on the element 56a of the first desiccant rotor 56 is removed to the third ventilation path. The outside air flowing through the passage 51c is heated by the heat source 59 to be released into the air. Further, the cooled air in the air-conditioned space B flowing through the fourth ventilation path 51d has a high relative humidity, and the moisture in the air is efficiently adsorbed to the element 58a of the second desiccant rotor 58.

  Thus, according to the air conditioning apparatus of the present embodiment, similarly to the first embodiment, the air flows through the first ventilation path 51a whose temperature has been increased by being dehumidified by the first desiccant rotor 56. Air can be reliably cooled by the sensible heat exchanger 57.

  Further, the second desiccant rotor 58 adsorbs moisture in the air flowing through the fourth ventilation path 51d and releases it into the air flowing through the second ventilation path 51b, thereby releasing the second ventilation. The air flowing through the passage 51b is discharged as exhaust gas, and the outside air is circulated through the third ventilation passage 51c to release the moisture adsorbed on the first desiccant rotor 56. Therefore, the second desiccant rotor 58 Without using the moisture-containing air for the regeneration of the first desiccant rotor 56, the outside air separately flowing through the third ventilation path 51c can be used for the regeneration of the first desiccant rotor 56. The element 56a can be regenerated by reliably releasing the moisture adsorbed on the desiccant rotor 56 into the air flowing through the third ventilation path 51c.

  Further, since the air in the air-conditioned space B is circulated through the fourth ventilation path 51c so that moisture is adsorbed by the second desiccant rotor 58, the air that has been cooled and has a high relative humidity is second desiccant. The element 58a of the rotor 58 can be brought into contact, and moisture in the air can be efficiently adsorbed to the element 58a.

The element 64a is made to adsorb moisture contained in the air. The air whose absolute humidity has been reduced by the first desiccant rotor 64 is heat-exchanged with the air flowing through the second ventilation path 61b by the sensible heat exchanger 65, and supplied to the conditioned space A as supply air (SA). In the second ventilation path 61b, the return air (RA) circulated from the air-conditioned space A by the second blower 63 and the outside air (OA) circulated from the outside contact the element 66a of the second desiccant rotor 66. As a result, the moisture adsorbed on the element 66a is released into the air flowing through the second ventilation path 61b. The air whose absolute humidity has been increased by the second desiccant rotor 66 is subjected to heat exchange with the air flowing through the first ventilation path 61a by the sensible heat exchanger 65, and then discharged to the outside as exhaust (EA). In the third ventilation path 61c, the outside air (OA) circulated from the outside by the first blower 63 is heated by the first heat exchanger 72 and brought into contact with the element 64a of the first desiccant rotor 64. Thus, the moisture adsorbed on the element 64a evaporates and is released into the air, and the air that has absorbed the moisture is discharged to the outside as exhaust (EA). Further, in the fourth ventilation path 61d, the return air (RA) circulated from the air-conditioned space A by the first blower 62 is cooled by the second heat exchanger 73, and the cooled air is cooled to the second desiccant rotor 66. In contact with the element 66a. Air that has been cooled and increased in relative humidity is brought into contact with the element 66a to adsorb moisture contained in the air to the element 66a, and the air whose absolute humidity has been reduced is supplied into the conditioned space A as supply air (SA). Supply.

  When moisture is adsorbed by the first desiccant rotor 64 in the first ventilation path 61a, the temperature of the air flowing through the first ventilation path 61a rises due to condensation heat of moisture. Further, when moisture is released from the second desiccant rotor 66 in the second ventilation path 61b, the temperature of the air flowing through the second ventilation path 61b decreases due to the evaporation heat of moisture. The air flowing through the first ventilation path 61 a is cooled and supplied to the air-conditioned space A by exchanging heat of these air with the sensible heat exchanger 65. In addition, the air flowing through the second ventilation path 61b humidified by the second desiccant rotor 66 is discharged to the outside, and moisture adsorbed on the element 64a of the first desiccant rotor 64 is removed to the third ventilation path. The outside air flowing through 61c is heated by the first heat exchanger 72 to be released into the air. Further, the air cooled by the second heat exchanger 73 flowing through the fourth ventilation path 61d has a high relative humidity, and the moisture in the air is efficiently adsorbed to the element 66a of the second desiccant rotor 66.

  When performing the humidification operation, as shown in FIG. 8, first, the first blower 62, the second blower 63, the first desiccant rotor 64, the second desiccant rotor 66, and the compressor 71 are operated. At the same time, the refrigerant circuit 70 is switched to the humidifying operation flow path by the four-way valve 75. Thereby, in the 1st ventilation path 61a, the return air (RA) circulated from the air-conditioning space A by the 1st air blower 62 and the external air (OA) circulated from the outside are supplied to the element 64a of the first desiccant rotor 64. The moisture adsorbed on the element 64a is released into the air. The air whose absolute humidity has been raised by the first desiccant rotor 64 is heat-exchanged with the air flowing through the second ventilation path 61b by the sensible heat exchanger 65, and supplied to the conditioned space A as supply air (SA). In the second ventilation path 61b, the return air (RA) circulated from the air-conditioned space A by the second blower 63 and the outside air (OA) circulated from the outside contact the element 66a of the second desiccant rotor 66. As a result, moisture contained in the air is adsorbed to the element 66a. The air whose absolute humidity has been reduced by the second desiccant rotor 66 is subjected to heat exchange with the air flowing through the first ventilation path 61a by the sensible heat exchanger 65, and then discharged to the outside as exhaust (EA). In the third ventilation path 61 c, the outside air (OA) circulated from the outside by the second blower 63 is cooled by the first heat exchanger 72, and the cooled air is sent to the elements of the first desiccant rotor 64. 64a is brought into contact. By bringing the cooled air into contact with the element 64a of the first desiccant rotor 64, moisture contained in the air is adsorbed to the element 64a, and the air whose absolute humidity has been reduced by the first desiccant rotor 64 is exhausted (EA ) To the outside. Further, in the fourth ventilation path 61d, the return air (RA) circulated from the air-conditioned space A by the first blower 62 is heated by the second heat exchanger 73, and the heated air is supplied to the second desiccant rotor 66.

Further, when moisture is adsorbed by the second desiccant rotor 66 in the second ventilation path 61b, the temperature of the air flowing through the second ventilation path 61b rises due to the condensation heat of the moisture. The air flowing through the first ventilation path 61a is heated and supplied to the air-conditioned space A by exchanging heat of these air with the sensible heat exchanger 65. The air flowing through the second ventilation path 61b dehumidified by the second desiccant rotor 66 is discharged to the outside, and moisture contained in the outside air flowing through the third ventilation path 61c is removed from the first desiccant rotor 64. It is adsorbed to the element 64a. Further, the air heated by the second heat exchanger 73 flowing through the fourth ventilation path 61d has a low relative humidity, and efficiently releases moisture from the element 66a of the second desiccant rotor 66.

  Further, the second desiccant rotor 66 adsorbs moisture in the air flowing through the fourth ventilation path 61d and releases it into the air flowing through the second ventilation path 61b, thereby releasing the second ventilation. The air flowing through the path 61b is discharged as exhaust gas, and the outside air is circulated through the third ventilation path 61c to release the moisture adsorbed on the first desiccant rotor 64. Therefore, the second desiccant rotor 66 Without using the moisture-containing air for the regeneration of the first desiccant rotor 64, the outside air separately flowing through the third ventilation path 61c can be used for the regeneration of the first desiccant rotor 64. The element 64a can be regenerated by reliably releasing the moisture adsorbed on the desiccant rotor 64 into the air flowing through the third ventilation path 61c.

  In addition, the air in the conditioned space A flowing through the fourth ventilation path is cooled by the second heat exchanger, and moisture contained in the air is adsorbed by the second desiccant rotor 66 and supplied to the conditioned space A. Therefore, the air dehumidified by the second desiccant rotor 66 can be supplied to the conditioned space A, and the air in the conditioned space A can be dehumidified more reliably.

  In addition, the air in the conditioned space A and the outside air are circulated through the first ventilation path 61a, and the outside air and the air in the conditioned space A are circulated through the second ventilation path 61b. While being dehumidified, the air-conditioned space A can be ventilated by the outside air cooled by the sensible heat exchanger 65, so that the absolute humidity can be lowered and the increase of the air-conditioning load can be prevented.
