At the same time, by controlling the operating status of the first heat exchange component 2 and the second heat exchange component 3, the temperature and / or humidity of the air flow entering the fuselage 1 is controlled to switch between the air purification mode, the dehumidification mode and the temperature adjustment mode.

[0036] In some embodiments, a throttling assembly 7 and an air compression assembly 8 are further included; the air compression assembly 8 is respectively connected to the first heat exchange assembly 2 and the second heat exchange assembly 3, and the first heat exchange assembly 2 and the second heat exchange assembly 3 are connected through the throttling assembly 7. The throttling assembly 7 is used to cool down and reduce the pressure of the refrigerant flowing out of the first heat exchange assembly 2 or the second heat exchange assembly 3, and the air compression assembly 8 is mainly used to compress the refrigerant so that the refrigerant enters the first heat exchange assembly 2 or the second heat exchange assembly 3 to exchange heat with the air.

[0037] In some embodiments, the air compression component 8 includes a reversing component 81 and a compressor 82; the reversing component 81 is connected to the first heat exchange component 2 and the second heat exchange component 3 respectively to form a first circulation loop; the reversing component 81 is connected to the compressor 82 to form a second circulation loop; the first circulation loop is connected to the second circulation loop, and the reversing component 81 is used to change the flow direction of the liquid in the first circulation loop. Specifically, the reversing component 81 includes a four-way 811 and a slide valve 812, and the slide valve 812 is arranged in the four-way 811. The setting of the slide valve 812 is used to change the connection relationship between the four-way 811 and the first heat exchange component 2, the second heat exchange component 3 and the compressor 82, thereby changing the flow direction of the refrigerant in the first circulation loop and the second circulation loop, switching the operating state of the first heat exchange component 2 and the second heat exchange component 3, and realizing the air handling mode switching of the air handling unit.

[0038] In some embodiments, the first heat exchange assembly 2 includes a first heat exchanger 21 and an indoor air blower 22, and the indoor air blower 22 is arranged between the indoor air outlet 14 and the first heat exchanger 21; the second heat exchange assembly 3 includes a second heat exchanger 31 and an outdoor exhaust fan 32, and the outdoor exhaust fan 32 is arranged between the outdoor air outlet 12 and the second heat exchanger 31. The indoor air blower 22 and the outdoor exhaust fan 32 are respectively used to guide the air on the corresponding channels, specifically, the indoor air blower 22 is used to guide the return air channel 16, the fresh air channel 15 and the dehumidification channel, and the outdoor exhaust fan 32 is mainly used to guide the heat dissipation channel 17. The first heat exchanger 21 and the second heat exchanger 31 are used to switch their own operating states according to the actual mode, so that one of the first heat exchanger 21 and the second heat exchanger 31 is used as a condenser and the other is used as an evaporator to process the air, so as to realize the cooling, heating and dehumidification functions of the air purifier. The switching of the operating states of the first heat exchanger 21 and the second heat exchanger 31 is achieved by changing the refrigerant flow direction through the reversing component 81 .

[0039] In some embodiments, the air purification mode is specifically: controlling the regulating component 6 so that the indoor return air outlet 13 is connected to the indoor air supply outlet 14 through the first filter component 4, or the outdoor fresh air outlet 11 is connected to the indoor air supply outlet 14 through the second filter component 5. In the air purification mode, the first heat exchange component 2 and the second heat exchange component 3 are not started; the air purification mode includes an indoor purification mode and a fresh air purification mode, wherein, in the indoor purification mode, the indoor return air outlet 13 is connected to the indoor air supply outlet 14 through the first filter component 4 to form a return air channel 16, so that the indoor air enters the indoor environment after purification; in the fresh air purification mode, the outdoor fresh air outlet 11 is connected to the indoor air supply outlet 14 through the second filter component 5 to form a fresh air channel 15, so that the fresh air enters the indoor environment after purification.

[0040] Specifically, the air purification mode includes the following two modes: (1) Indoor purification mode: the third regulating valve 63 is opened, and the other regulating valves are closed to form a return air channel 16. At this time, the air passes through the indoor return air port 13, the first filter component 4, the first heat exchanger 21 and the indoor fan 22 in sequence and is discharged from the indoor air supply port 14. Since the first heat exchanger 21 is not started, the humidity and temperature of the air are not adjusted in this mode; (2) Fresh air purification mode: the second regulating valve 62, the fourth regulating valve 64 and the sixth regulating valve 66 are opened, and the other regulating valves are closed to form a fresh air channel 15. The air passes through the outdoor fresh air port 11, the second filter component 5, the first heat exchanger 21 and the indoor fan 22 in sequence and is discharged from the indoor air supply port 14. Since the first heat exchanger 21 is not started, the humidity and temperature of the air are not adjusted in this mode.

[0041] In some embodiments, the dehumidification mode is specifically to control the regulating component 6 so that the indoor return air outlet 13 is connected to the indoor air outlet 14 through the first filter component 4, the second heat exchange component 3 and the first heat exchange component 2 in sequence, or the outdoor fresh air outlet 11 is connected to the indoor air outlet 14 through the second filter component 5, the second heat exchange component 3 and the first heat exchange component 2 in sequence. The dehumidification mode includes a fresh air dehumidification mode and an indoor dehumidification mode, which are respectively used to dehumidify the outdoor air and the indoor air to meet the different needs of users. In the dehumidification mode, the slide valve 812 moves to the first position, and the high-temperature and high-pressure refrigerant enters the first heat exchanger 21 after being compressed by the compressor 82 to exchange heat with the air and form a medium-temperature and high-pressure refrigerant, and forms a low-temperature and low-pressure refrigerant through the throttling component 7 and enters the second heat exchanger 31. The refrigerant in the second heat exchanger 31 exchanges heat with the high-humidity air flowing through the surface of the second heat exchanger 31, and then flows back to the compressor 82 through the slide valve 812.

[0042] Specifically, the dehumidification mode includes the following two modes: (1) Indoor dehumidification mode: the first regulating valve 61, the second regulating valve 62 and the fifth regulating valve 65 are all opened to form an indoor dehumidification channel 1, and the first heat exchanger 21 and the second heat exchanger 31 are started. At this time, the first heat exchanger 21 acts as a condenser and the second heat exchanger 31 acts as an evaporator. After the air passes through the first filter component 4, the second heat exchanger 31 and the first heat exchanger 21 in sequence, it is discharged from the indoor air outlet 14 driven by the indoor blower 22; (2) Fresh air dehumidification mode: the second regulating valve 62, the fifth regulating valve 65 and the sixth regulating valve 66 are all opened to form an outdoor dehumidification channel 2, and the first heat exchange component 2 and the second heat exchange component 3 are started. At this time, the first heat exchanger 21 acts as a condenser and the second heat exchanger 31 acts as an evaporator. After the air passes through the second filter component 5, the second heat exchanger 31 and the first heat exchanger 21 in sequence, it is discharged from the indoor air outlet 14 driven by the indoor blower 22. Among them, in the above two dehumidification modes, when high-humidity air flows through the second heat exchanger 31, the moisture in the high-humidity air is condensed by the second heat exchanger 31 to achieve dehumidification. The dehumidified low-temperature and low-humidity air is then heated by the first heat exchanger 21, so that the air enters the room at a suitable temperature.

[0043] In some embodiments, the temperature adjustment mode is specifically to control the adjustment component 6 so that the indoor return air outlet 13 is connected to the indoor air supply outlet 14 through the first filter component 4 and the first heat exchange component 2 in sequence, and the outdoor fresh air outlet 11 is connected to the outdoor exhaust outlet 12 through the second filter component 5 and the second heat exchange component 3 in sequence. The temperature adjustment mode includes a cooling mode and a heating mode, which are used to cool or heat the air entering the air handling unit respectively. In the temperature adjustment mode, the first heat exchange component 2 and the second heat exchange component 3 are both started.

[0044] Specifically, the temperature adjustment mode includes the following two modes: (1) cooling mode: the first heat exchanger 21 is an evaporator, the second heat exchanger 31 is a condenser, the third regulating valve 63, the fourth regulating valve 64, the sixth regulating valve 66 and the seventh regulating valve 67 are opened, and the other regulating valves are closed; the indoor air flows through the first filter component 4, the first heat exchanger 21 and the indoor blower 22 in sequence, and is discharged from the indoor air outlet 14, which plays a role in cooling the indoor air; the outdoor air flows through the second filter component 5, the second heat exchanger 31 and the outdoor exhaust fan 32 in sequence, and is discharged from the outdoor exhaust outlet 12, which is used to dissipate the heat from the second heat exchanger 31. During this process, the slide valve 812 is in the second position. After being compressed by the compressor 82, the high-temperature and high-pressure refrigerant enters the second heat exchanger 31 to exchange heat with the air and form a medium-temperature and high-pressure refrigerant. The low-temperature and low-pressure refrigerant is formed through the throttling component 7 and enters the first heat exchanger 21. The refrigerant in the first heat exchanger 21 exchanges heat with the high-temperature air flowing through the surface of the first heat exchanger 21, and then flows back to the compressor 82 through the slide valve 812 to complete the refrigeration cycle.

[0045] (2) Heating mode: the first heat exchanger 21 is a condenser, the second heat exchanger 31 is a heat exchanger, the third regulating valve 63, the fourth regulating valve 64, the sixth regulating valve 66 and the seventh regulating valve 67 are opened, and the other regulating valves are closed; the indoor air flows through the first filter component 4, the first heat exchanger 21 and the indoor blower 22 in sequence, and is discharged from the indoor air outlet 14, which plays a role in heating the indoor air; the outdoor air flows through the second filter component 5, the second heat exchanger 31 and the outdoor exhaust fan 32 in sequence, and is discharged from the outdoor exhaust outlet 12, which plays a role in heating the second heat exchanger 31. During this process, the slide valve 812 is in the first position. After being compressed by the compressor 82, the high-temperature and high-pressure refrigerant vapor enters the first heat exchanger 21 to exchange heat with the air and form a medium-temperature and high-pressure refrigerant liquid. The low-temperature and low-pressure refrigerant is formed through the throttling component 7 and enters the second heat exchanger 31. The refrigerant in the second heat exchanger 31 exchanges heat with the low-temperature air flowing through the surface of the second heat exchanger 31 to form refrigerant vapor, and then flows back to the compressor 82 through the slide valve 812 to complete the heat cycle.

[0053] In this embodiment, in the air purification mode, the first heat exchange component 2 and the second heat exchange component 3 are not started; the air purification mode includes an indoor purification mode and a fresh air purification mode, wherein, in the indoor purification mode, the indoor return air outlet 13 is connected with the indoor air supply outlet 14 through the first filter component 4 to form a return air channel 16, so that the indoor air enters the indoor environment after purification; in the fresh air purification mode, the outdoor fresh air outlet 11 is connected with the indoor air supply outlet 14 through the second filter component 5 to form a fresh air channel 15, so that the fresh air enters the indoor environment after purification.

[0054] Specifically, the air purification mode includes the following two modes:

[0055] (1) Indoor purification mode: refer to Figure 2, the third regulating valve 63 is opened, and the other regulating valves are closed to form a return air channel 16. At this time, the air passes through the indoor return air port 13, the first filter component 4, the first heat exchanger 21 and the indoor blower 22 in sequence and is discharged from the indoor air supply port 14.

The low-temperature and low-pressure refrigerant is formed through the throttling component 7 and enters the first heat exchanger 21. The refrigerant in the first heat exchanger 21 exchanges heat with the high-temperature air flowing through the surface of the first heat exchanger 21, and then flows back to the compressor 82 through the slide valve 812 to complete the refrigeration cycle.

[0064] (2) Heating mode: refer to Figure 7 The first heat exchanger 21 is a condenser, the second heat exchanger 31 is a heat exchanger, the third regulating valve 63, the fourth regulating valve 64, the sixth regulating valve 66 and the seventh regulating valve 67 are opened, and the other regulating valves are closed; the indoor air flows through the first filter component 4, the first heat exchanger 21 and the indoor fan 22 in sequence, and is discharged from the indoor air outlet 14, which plays a role in heating the indoor air; the outdoor air flows through the second filter component 5, the second heat exchanger 31 and the outdoor exhaust fan 32 in sequence, and is discharged from the outdoor exhaust outlet 12, which is used to heat the second heat exchanger 31. During this process, the slide valve 812 is in the first position. After being compressed by the compressor 82, the high-temperature and high-pressure refrigerant vapor enters the first heat exchanger 21 to exchange heat with the air and form a medium-temperature and high-pressure refrigerant liquid. The low-temperature and low-pressure refrigerant is formed through the throttling component 7 and enters the second heat exchanger 31. The refrigerant in the second heat exchanger 31 exchanges heat with the low-temperature air flowing through the surface of the second heat exchanger 31 to form refrigerant vapor, and then flows back to the compressor 82 through the slide valve 812 to complete the heat cycle.
