[0031] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0032] According to an embodiment of the present utility model, an air conditioning unit is provided. Figures 1 to 4The air-conditioning unit includes: a first heat exchange module 1, the first heat exchange module 1 includes an air inlet channel 11, an air inlet 12 and an air outlet 13; the air inlet 12 and the air outlet 13 are respectively connected to the air inlet channel 11; a first heat exchange component 2 is arranged in the air inlet channel 11; a second heat exchange module 3, the second heat exchange module 3 has a heat exchange cavity 31, and a second heat exchange component 32 connected to the first heat exchange component 2 is arranged in the heat exchange cavity 31; a partition structure 4, the partition structure 4 is connected to the first heat exchange module 1, the partition structure 4 is connected to the second heat exchange module 3, and the air inlet channel 11 and the heat exchange cavity 31 are respectively located on opposite sides of the partition structure 4; a dehumidification structure 5 for removing moisture in the air, and the dehumidification structure 5 can be selectively connected to the air inlet 12.

[0033] By adopting the above-mentioned arrangement, the indoor and outdoor units of the air-conditioning unit are integrated into a whole. The dehumidification structure 5 is connected to the air inlet channel 11 of the air-conditioning unit according to the different requirements of different working conditions of the air-conditioning unit, so that the incoming air is processed differently according to different working conditions. The structure of the entire system is compact, making it easier to connect the indoor and outdoor units, thereby solving the technical problem that the split indoor and outdoor units are not conducive to online control.

[0034] Specifically, the dehumidification structure 5 of this embodiment is a rotary dehumidifier.

[0035] See also Figure 1 , Figure 3 In the air conditioning unit of this embodiment, the dehumidification structure 5 includes a dehumidification air outlet 51 connected to the air inlet 12, and the air inlet channel 11 includes a first air inlet channel 111 connected to the dehumidification air outlet 51; the first air inlet channel 111 is connected to the air outlet 13. In this way, the dehumidification structure 5 can absorb the airflow entering the air conditioning unit from the outside, thereby achieving the dehumidification effect.

[0036] Specifically, the dehumidification structure 5 of this embodiment is a rotary dehumidifier.

[0037] See also Figure 1 In the air conditioning unit of this embodiment, the air conditioning unit further includes: a damper component 6, the damper component 6 has a fresh air port 61 connected to the air inlet 12, the air inlet channel 11 includes a second air inlet channel 11 connected to the fresh air port 61; the second air inlet channel 11 is connected to the air outlet 13, the second air inlet channel 112 is arranged to be spaced apart from the first air inlet channel 111; the opening of the fresh air port 61 is adjustable. In this way, when the dehumidification structure 5 is required to dehumidify, the damper component 6 is closed, so that the airflow enters the second air inlet channel 11, so that the dehumidification structure 5 dehumidifies the airflow, and when the dehumidification structure is not required to dehumidify, the damper component 6 is opened, and the airflow enters from the second air inlet channel 11.

[0038] In the air conditioning unit of this embodiment, see Figure 1The first heat exchange assembly 2 includes an evaporation component 21. The first air inlet channel 111 and the second air inlet channel 112 are both connected to the evaporation component 21. The evaporation component 21 is used to absorb the heat of the fluid in the first air inlet channel 111 and the second air inlet channel 112. The evaporation component 21 is located between the air inlet 12 and the air outlet 13. In this way, the airflow entering from the first air inlet channel 111 and the second air inlet channel 112 can pass through the evaporation component 21, so that the evaporation component 21 performs dehumidification.

[0039] In the air conditioning unit of this embodiment, see Figure 1 The first heat exchange assembly 2 includes a condensing component 22, which is used to dissipate heat. The condensing component 22 is located on a side of the evaporating component 21 away from the first air inlet channel 111; the condensing component 22 is located between the evaporating component 21 and the air outlet 13. In this way, the airflow entering from the first air inlet channel 111 and the second air inlet channel 112 passes through the evaporating component 21, and then passes through the condensing component 22 for heat exchange.

[0040] See also Figure 2 In the air conditioning unit of this embodiment, a compressor 7 is arranged in the first air inlet passage 111, and the compressor 7 is connected to both the evaporation component 21 and the condensation component 22. In this way, the compressor 7 is arranged in the first air inlet passage 111 by utilizing the internal structure of the air conditioning unit, thereby saving the occupied space of the air conditioning unit.

[0041] In the air conditioning unit of this embodiment, the air conditioning unit further includes a return air vent 14, which is connected to both the first air inlet channel 111 and the second air inlet channel 112, and is connected to the outside of the air conditioning unit; the return air vent 14 is located on the side of the evaporation component 21 away from the air outlet 13. In this way, when fresh air is not needed, the indoor air is circulated internally through the return air vent 14 to ensure the function of the air conditioning unit.

[0042] In the air conditioning unit of this embodiment, the air conditioning unit further includes a fan assembly 8, which is located on the side of the evaporation component 21 away from the return air port 14, and the fan assembly 8 is used to blow airflow toward the air outlet 13. In this way, the fan assembly 8 is arranged at the above position, so that the fan assembly 8 can drive the airflow to circulate no matter which mode the air conditioning unit is in.

[0043] See also Figure 4In the air-conditioning unit of the present embodiment, the air-conditioning unit includes a fixed bracket 9, and the first heat exchange module 1 and the second heat exchange module 3 are both connected to the fixed bracket 9; the air inlet 12, the air outlet 13 and the return air outlet 14 are all opened on the fixed bracket 9; the fan assembly 8 includes: a motor bracket 81, which is connected to the fixed bracket 9; a driving motor 82, and the driving motor 82 is arranged on the motor bracket 81; a fan impeller 84 is arranged on the output shaft of the driving motor 82; a thermal insulation volute 83, and the thermal insulation volute 83 is covered on the fan impeller 84, and the thermal insulation volute 83 has an exhaust port 831 arranged opposite to the air outlet 13, and a thermal insulation layer is arranged in the thermal insulation volute 83.

[0044] Specifically, in this embodiment, the thermal insulation foam board of the fan section of the centrifugal fan without volute is eliminated, a homemade square volute is added, and sponge insulation is added on the surface of the volute. There is no need to consider the sealing and insulation of the fan section of the unit, thus avoiding condensation in the fan section and improving the reliability of the unit. The two schemes of the fan section foam structure and the volute-free and volute-added scheme are simulated. The volute-free fan plus volute scheme is better than the existing fan section foam board scheme, and the air volume can be increased by about 5%.

[0045] In the air conditioning unit of this embodiment, the partition structure 4 includes a partition plate 41, and the second heat exchange assembly 32 includes a plurality of condensing fans 321, which are arranged on the partition plate 41, and the exhaust ports 831 of the plurality of condensing fans are all oriented toward the side of the partition plate 41 away from the air inlet channel 11. In this way, the internal space of the air conditioning unit is divided into an upper layer and a lower layer, the lower layer is used for airflow processing, and the upper layer is used for heat dissipation, so that the space is reasonably utilized and the structure is simplified.

[0046] Embodiment 1:

[0047] In the air-conditioning unit of this embodiment, the first heat exchange module 1 and the second heat exchange module 3 are two independent systems so as not to affect each other; thereby integrating the inner and outer units of the air-conditioning unit with an integral steel frame structure to meet the hoisting requirements for switching the operating position of the unit. The fan section cancels the original foam board insulation section, adds an insulation volute, changes the internal air duct, and increases the air volume and air supply static pressure of the unit.

[0048] Embodiment 2:

[0049] See also Figure 4The air-conditioning unit of this embodiment can be controlled into two working conditions, normal working conditions and extreme working conditions. After the unit is turned on, the unit will operate according to the normal working conditions first. When it is detected that "fresh air humidity" > "set value default 21g / kg" + "humidity content tolerance value 0.5g / kg" for 10 consecutive seconds, it will switch to the extreme working condition; when it is detected that "fresh air humidity" < "set value default 21g / kg" - "humidity content tolerance value 0.5g / kg" for 10 consecutive seconds, it will switch to the extreme working condition; when it is detected that "set value default 21g / kg" - "humidity content tolerance value 0.5g / kg" ≤ "fresh air humidity" ≤ "set value default 21g / kg" + "humidity content tolerance value 0.5g / kg" for 10 consecutive seconds, the current operating mode will be maintained.

[0050] In this embodiment, the above-mentioned “fresh air humidity content” refers to the humidity of the air flow entering from the air inlet 12 .

[0051] Specifically, when the air conditioning unit is in normal working condition: the dehumidification structure 5 and the electric heating do not work. When there are people working in the cabin, the unit introduces fresh air, the air valve component 6 is opened, and the fresh air does not pass through the dehumidification structure 5, but directly passes through the first air inlet channel 111 to mix with the return air, and then passes through the evaporation component 21 to cool and dehumidify. The compressor 7 is loaded and unloaded according to the required moisture content of the supply air. According to the actual operation, only one fan can be operated, and then the temperature is adjusted to the supply air target temperature through the condensation component 22, and finally the treated air is sent into the cabin through the fan port for air exchange; when it is not necessary to introduce fresh air, the indoor air passes through the unit return air port, passes through the evaporation component 21 to cool down, and then is sent out from the air port to achieve the purpose of lowering the indoor temperature. The non-operation of the electric heating reduces the energy consumption of the unit. The normal working condition operation time accounts for more than 90% of the unit operation time, which can greatly reduce the energy consumption of the unit.

[0052] When the air conditioning unit is in extreme working conditions: when the fresh air is highly humid, the unit introduces fresh air, the air valve component 6 inside the unit is closed, the fresh air is dehumidified through the second air inlet channel 112 and mixed with the return air, and then cooled and dehumidified through the evaporation component 21, and the condensing reheater fine-tunes the supply air temperature and delivers it into the room.
