Referring to fig. 1 to 3, an embodiment of the present disclosure provides a device for adjusting humidity, including a refrigerant circuit, an air duct, and a fan assembly. The refrigerant loop is formed by connecting a compressor 11, a first heat exchanger 12, a second heat exchanger 13, a throttling mechanism 14 and a four-way valve 15; the first heat exchanger 12 and the second heat exchanger 13 are both coated with a dehumidifying material; the air channel comprises a heat exchange cavity 21 and a pipeline assembly 22; a first heat exchanger 12, a second heat exchanger 13 and a reversing plate 23 capable of switching directions are arranged in the heat exchange cavity 21; the pipeline assembly 22 is used for introducing gas into the heat exchange cavity 21; the reversing plate 23 changes the flow direction of the gas flowing into the heat exchange cavity 21 by switching the direction, so that the first heat exchanger 12 performs adsorption and dehumidification and the second heat exchanger 13 performs desorption and regeneration, or the first heat exchanger 12 performs desorption and regeneration and the second heat exchanger 13 performs adsorption and dehumidification; the fan assembly includes a first fan 31 and a second fan 32; the first fan 31 is disposed at the air outlet 41, the second fan 32 is disposed at the air supply outlet 42, and both the air outlet 41 and the air supply outlet 42 are communicated with the pipeline assembly 22.

Among them, the reversing plate 23 is a rotatable member.

Adopt the device for adjusting humidity of this disclosed embodiment, can switch the direction through reversing plate 23 and cooperate with pipeline assembly 22, the control flows in the gas flow direction of wind channel and heat exchange cavity 21 to make first heat exchanger 12 adsorb dehumidification and second heat exchanger 13 desorption regeneration, perhaps, first heat exchanger 12 desorption regeneration and second heat exchanger 13 adsorb the dehumidification. The humidification or dehumidification of the indoor air is realized by performing adsorption dehumidification or desorption regeneration on the first heat exchanger 12 and the second heat exchanger 13, respectively.

In addition, a first fan 31 is provided at the air outlet 41 to adjust the amount of air discharged from the air duct to the outside for desorption regeneration or adsorption dehumidification. The second fan 32 is provided at the air blowing port 42 to adjust the amount of air to be blown from the air duct into the room for adsorption dehumidification or desorption regeneration. The independent adjustment of the air quantity of the desorption regeneration side and the air quantity of the adsorption dehumidification side is realized, the limitation of the air quantity by user demands is avoided, and the humidification or dehumidification effect is improved.

Specifically, when the direction changing plate 23 is in the first direction, the first heat exchanger 12 is an evaporator, and the second heat exchanger 13 is a condenser, the first heat exchanger 12 absorbs heat so that the heat of the dehumidifying material coated on the surface thereof is absorbed, and thus the moisture in the gas is adsorbed, thereby realizing adsorption and dehumidification of the circulating gas. At this time, the second fan 32 provided in the air blowing port 42 can independently control the air after adsorption and dehumidification to enter the room from the air blowing port 42, thereby achieving indoor dehumidification. The second heat exchanger 13 releases heat to allow the dehumidifying material coated on the surface thereof to be heated, desorbed and regenerated so that moisture is released, thereby humidifying the circulating gas, and at this time, the gas after desorption and regeneration is separately controlled to be discharged to the outside by the first fan 31 provided at the air outlet 41.

Specifically, when the direction changing plate 23 is in the second direction, the four-way valve 15 is switched, the first heat exchanger 12 is a condenser, the second heat exchanger 13 is an evaporator, and the first heat exchanger 12 performs desorption and regeneration on the dehumidifying material so that the circulating gas is humidified. At this time, the desorbed and regenerated gas is discharged to the outside of the room by the first fan 31 provided in the air outlet 41. The second heat exchanger 13 adsorbs and dehumidifies the gas flowing therethrough by using a dehumidifying material. At this time, the second fan 32 provided in the air blowing port 42 can independently control the air after adsorption and dehumidification to enter the room from the air blowing port 42, thereby achieving indoor dehumidification.

The larger the rotation speed of the first fan 31 is, the larger the air volume discharged to the outside is, and the smaller the air volume for desorption and regeneration of the desiccant at the first heat exchanger 12 or the second heat exchanger 13 is; on the contrary, the smaller the rotation speed of the first fan 31 is, the larger the air volume for desorption and regeneration of the dehumidifying material is, so that the effect of desorption and regeneration can be greatly improved, and the dehumidifying materials on the surfaces of the first heat exchanger 12 and the second heat exchanger 13 can keep the capacity of absorbing moisture in the air. The independent adjustment of the air quantity of the desorption regeneration side and the air quantity of the adsorption dehumidification side is realized, the limitation of the air quantity by user demands is avoided, and the humidification or dehumidification effect is improved.

Similarly, when the direction changing plate 23 is in the first direction, the first heat exchanger 12 is a condenser, and the second heat exchanger 13 is an evaporator, the first heat exchanger 12 desorbs and regenerates the desiccant so that the flow gas is humidified. At this time, the humidified gas can be independently controlled to enter the room from the air blowing port 42 by the second fan 32 provided at the air blowing port 42, thereby humidifying the room. The second heat exchanger 13 adsorbs and dehumidifies the gas flowing therethrough, and at this time, the gas subjected to adsorption and dehumidification is discharged to the outside by being independently controlled by the first fan 31 provided at the air outlet 41.

Similarly, when the reversing plate 23 is operated in the second direction, the four-way valve 15 is switched to make the first heat exchanger 12 as an evaporator and the second heat exchanger 13 as a condenser, the first heat exchanger 12 adsorbs and dehumidifies the circulating gas, and at this time, the second fan 32 disposed at the air supply opening 42 can independently control the dehumidified gas to enter the room from the air supply opening 42 for dehumidification. The second heat exchanger 13 desorbs and regenerates the desiccant material so that the circulating gas is humidified. At this time, the discharge of the humidified gas to the outside is controlled by the first fan 31 provided at the air outlet 41 alone.

The larger the rotation speed of the first fan 31 is, the larger the air volume discharged to the outside is, and the smaller the air volume for the relative adsorption and dehumidification of the dehumidifying material at the first heat exchanger 12 or the second heat exchanger 13 is; on the contrary, the smaller the rotating speed of the first fan 31 is, the larger the air volume for adsorption and dehumidification of the dehumidifying material is, the adsorption and dehumidification effects can be greatly improved, and the humidification performance of the device for adjusting humidity is improved. The independent adjustment of the air quantity of the desorption regeneration side and the air quantity of the adsorption dehumidification side is realized, the limitation of the air quantity by user demands is avoided, and the humidification or dehumidification effect is improved.

Thus, as can be seen from the dotted line in fig. 2, the fresh air flows into the first pipeline 221 from the first fresh air inlet 43, the fresh air flowing into the heat exchange cavity 21 from the first pipeline 221 flows into the room for dehumidification from the fourth pipeline 224 through the air supply outlet 42 after being subjected to adsorption and dehumidification by the second heat exchanger 13, and the fresh air does not flow out from the air outlet 41 through the flow path of the fourth pipeline 224. Meanwhile, as can be seen from another broken line in fig. 2, the return air flows into the third pipeline 223 from the return air inlet 45, the return air flowing into the heat exchange cavity 21 from the third pipeline 223 is discharged from the second pipeline 222 through the air outlet 41 after being desorbed and regenerated for the desiccant material of the first heat exchanger 12, and the return air does not return to the room from the air outlet 42 through the flow path of the second pipeline 222.

Similarly, when the direction changing plate 23 is switched to the first direction, the first heat exchanger 12 is a condenser, and the second heat exchanger 13 is an evaporator, the first three-way valve 51 can control the exhaust port 41 to be disconnected from the flow paths of the second pipes 222 of the heat exchange chamber 21 and the air supply port 42, respectively, and the heat exchange chamber 21 and the air supply port 42 to be communicated with each other. The second three-way valve 52 can control the flow path of the fourth pipeline 224 of the air supply port 42 to be disconnected from the heat exchange cavity 21 and the air exhaust port 41, respectively, and the heat exchange cavity 21 and the air exhaust port 41 to be communicated with each other.

In this way, the fresh air flowing into the heat exchange cavity 21 from the first pipeline 221 is desorbed and regenerated by the first heat exchanger 12, flows into the room from the second pipeline 222 through the air supply outlet 42, and is humidified, and the fresh air does not flow out from the air outlet 41 through the flow path of the second pipeline 222.
