Further, the desiccant rotor 200 is rotatably assembled in the unit housing 100 and includes a regeneration section 201 located in the drying chamber 101 and a desiccant section 202 located in the desiccant chamber 102. In the present embodiment, the desiccant rotor 200 is horizontally assembled in the unit casing 100, an axis of the desiccant rotor 200 is set to be a vertical direction, and the desiccant rotor 200 can horizontally rotate around the vertical axis. The regeneration part 201 of the desiccant rotor 200 disposed in the drying chamber 101 is used for desorption regeneration, and the dehumidification part 202 of the desiccant rotor 200 disposed in the dehumidification chamber 102 is used for cooling dehumidification and adsorption dehumidification.

In the embodiment shown in fig. 2, the desiccant rotor 200 includes a rotor body 203 and a rotor motor 204 in driving connection with the rotor body 203, and the rotor motor 204 drives the rotor body 203 to rotate horizontally and slowly around the vertical axis.

The first condenser 301 is transversely disposed in the drying cavity 101 and located on the air intake side of the regeneration part 201, so that most of the heat released by the first condenser 301 can be absorbed by the regeneration part 201, and the desorption regeneration efficiency of the regeneration part 201 is improved. And, locate the side of airing exhaust of regeneration part 201 with outdoor exhaust 104, guide first condenser 301 on the one hand and contact with regeneration part 201 as soon as possible, on the other hand is the air that desorbs regeneration part 201 discharges fast for the air in the stoving chamber 101 flows unobstructed, and constantly has the new trend to get into in the stoving chamber 101. In the above scheme, the dehumidification cavity air inlet 105 is arranged at the air inlet side of the dehumidification part 202, and the indoor air outlet 106 is arranged at the air outlet side of the dehumidification part 202, so that on one hand, all or most of water molecules in the air entering the dehumidification cavity 102 from the dehumidification cavity air inlet 105 can be adsorbed by the dehumidification part 202, and thus the dehumidification effect is improved; on the other hand, the air in the dehumidification cavity 102 can flow smoothly, fresh air is kept to enter the dehumidification cavity 102, and the air dehumidified by the dehumidification part 202 can be guided to enter the room from the indoor air outlet 106.

And Type III adsorbent has better adsorptivity, and easy regeneration is strong in the air of relative high humidity ability of absorbing humidity, does not limit in this application.

In the embodiment shown in fig. 1, the refrigeration system 300 further includes a compressor 302 assembled in the drying cavity 101, an evaporator 303 assembled in the dehumidifying cavity 102, a throttling element 304 assembled in the dehumidifying cavity 102, and a conveying pipeline 305, in this embodiment, the throttling element 304 is connected between the first condenser 301 and the evaporator 303, and the first condenser 301 is also connected to the compressor 302 and the evaporator 303 through the conveying pipeline 305. In the present embodiment, the throttling element 304 may be an expansion valve, but is not limited thereto. In the present embodiment, the transfer line 305 includes a first line 3051 connecting the compressor 302 and the first condenser 301, a second line 3052, a third line 3053 connecting the evaporator 303 and the first condenser 301, a fourth line 3054, and a fifth line 3055 connecting the compressor 302 and the evaporator 303. The compressor 302 is connected to the first condenser 301 through a first pipe 3051, the first condenser 301 is connected to the evaporator 303 through a third pipe 3053, and the evaporator 303 is connected to the compressor 302 through a fifth pipe 3055.

In the above embodiment, the compressor 302 is a power of the refrigeration system cycle, and can compress the low-temperature and low-pressure refrigerant vapor to a high-temperature and high-pressure state, so that the refrigerant vapor can be condensed by using air or water at normal temperature as a cooling medium, and is delivered to the first condenser 301. Further, the first condenser 301 takes away heat of the high-temperature and high-pressure refrigerant vapor from the compressor 302, and cools and condenses the high-temperature and high-pressure refrigerant vapor into a high-pressure and normal-temperature refrigerant liquid. It should be noted that the pressure of the first condenser 301 is constant and high during the process of changing the refrigerant vapor into the refrigerant liquid. Since the refrigerant liquid at high pressure and normal temperature cannot be directly sent to the low-temperature evaporator 303, the pressure of the refrigerant liquid is reduced and the temperature of the refrigerant liquid can be reduced according to the one-to-one correspondence principle between the saturation pressure and the saturation temperature. Therefore, the refrigerant liquid at high pressure and normal temperature passes through the throttle element 304 to obtain a low-temperature and low-pressure refrigerant, and is sent to the evaporator 303 to be evaporated by heat absorption. The throttled low-temperature and low-pressure refrigerant liquid is evaporated (or boiled) in the evaporator 303 to become vapor, and the heat of the cooled substance is absorbed, so that the temperature of the substance is reduced, and the purpose of refrigeration is achieved, thereby cooling the surrounding air, and achieving the effects of cooling and dehumidifying the air. By such circulation, the first condenser 301 can continuously release heat, the heat released by the first condenser 301 is effectively utilized to provide an uninterrupted heat source for the regeneration part 201, an additional heating device is not required to be added, and the energy consumption of the whole fresh air dehumidifier 10 is reduced.

In the above embodiment, the fresh air dehumidifier 10 is a vertical fresh air dehumidifier. The vertical fresh air dehumidifier occupies a small area, and the vertical fresh air dehumidifier can be effectively utilized in the longitudinal space. For example, the compressor 302 is disposed at the bottom of the drying chamber 101, so as to effectively utilize the lower space of the drying chamber 101, and the compressor 302 has a large volume and a large weight, and is disposed at the bottom of the drying chamber 101, so that the center of gravity of the whole fresh air dehumidifier 10 is relatively low and stable. The evaporator 303 is obliquely disposed in the dehumidifying chamber 102 and is obliquely disposed on the air inlet side of the dehumidifying part 202, so that the lower space of the dehumidifying chamber 102 can be effectively utilized, the contact area with the dehumidifying part 202 can be increased, and the dehumidifying effect of the dehumidifying part 202 can be improved. In this embodiment, a water pan 107 is disposed in the dehumidification cavity 102, the water pan 107 is located at the bottom of the evaporator 303, and when the evaporator 303 is inclined, the generated condensed water flows to the water pan 107 along the heat exchange pipeline of the evaporator 303, so that the condensed water generated by the heat exchange pipeline of the evaporator 303 is timely treated, and the heat exchange effect of the evaporator 303 is prevented from being affected.

In some embodiments, the fresh air dehumidifier 10 further includes a flow regulating valve 307, and the first pipe 3051 and/or the second pipe 3052 is connected to the flow regulating valve 307. So configured, the refrigerant flow into the first condenser 301 and the second condenser 306 may be adjusted. In this embodiment, the second pipe 3052 is connected to the flow control valve 307. For example, when the temperature of the air dehumidified by the dehumidifying part 202 in the dehumidifying chamber 102 is low and a large amount of heat is required, the flow rate of the flow rate adjusting valve may be adjusted to increase the flow rate of the refrigerant entering the second condenser 306, thereby increasing the amount of heat released by the second condenser 306, thereby heating the dehumidified air to a predetermined temperature, and conversely, the flow rate of the flow rate adjusting valve may be decreased.
