[0059] This disclosure provides an air conditioning device, including an indoor unit 100, a heat exchange assembly 200, a humidification assembly 300, and a fan assembly 400. For example... Figure 1 and Figure 2As shown, the indoor unit 100 includes a fresh air inlet 111 and an indoor air outlet 112 forming a first air duct 110, and an indoor return air outlet 121 and a connecting port 122 forming a second air duct 120. The heat exchange assembly 200 includes a first heat exchanger 210, which is disposed within the first air duct 110. The humidification assembly 300 is disposed within the first air duct 110 and is located downstream of the heat exchange assembly 200 along the gas flow direction. The fan assembly 400 is disposed within the first air duct 110 and is located downstream of the humidification assembly 300 along the gas flow direction. Furthermore, the connecting port 122 is controllably connected to the first air duct 110 and is located upstream of the heat exchange assembly 200 along the gas flow direction.

[0060] In this embodiment, the heat exchange component 200 can be used to lower the temperature of the air flowing through the first air duct 110, achieving dehumidification when the air temperature drops to the dew point temperature. The heat exchange component 200 can also be used to raise the temperature of the air flowing through the first air duct 110 to further enhance the humidification effect. The humidification component 300 is used to increase the humidity of the air flowing through the first air duct 110. The fan component 400 is used to promote air circulation in the first air duct 110. Furthermore, by controlling the on / off state of the fresh air inlet 111 and the connecting port 122, outdoor fresh air and / or indoor air can enter the room through the indoor air outlet 112 of the first air duct 110, thereby achieving multiple humidification and dehumidification modes.

[0061] Optionally, the air conditioning equipment has a fresh air humidification mode, which corresponds to: the fresh air inlet 111 is open and the connection port 122 is closed, the humidification component 300 humidifies, and the first heat exchanger 210 is closed or running in heating mode.

[0062] In this embodiment, when the fresh air inlet 111 is open, outdoor fresh air enters the first air duct 110 through the fresh air inlet 111. When the connection port 122 is closed, indoor air cannot enter the first air duct 110 through the second air duct 120. When the humidification component 300 is humidifying, the outdoor fresh air circulating in the first air duct 110 can be humidified. When the first heat exchanger 210 is closed, the temperature of the outdoor fresh air circulating in the first air duct 110 is not affected. When the first heat exchanger 210 is operating in heating mode, the temperature of the outdoor fresh air circulating in the first air duct 110 can be increased, thereby improving the moisture absorption capacity of the outdoor fresh air and thus improving the humidification effect. Finally, the humidified outdoor fresh air enters the room from the indoor air outlet 112.

[0063] Optionally, the air conditioning equipment has a fresh air dehumidification mode, which corresponds to: the fresh air inlet 111 is open and the connection port 122 is closed, the humidification component 300 is closed, and the first heat exchanger 210 performs cooling dehumidification.

[0064] In this embodiment, with the fresh air inlet 111 open, outdoor fresh air enters the first air duct 110 through the fresh air inlet 111. With the connection port 122 closed, indoor air cannot enter the first air duct 110 through the second air duct 120. With the humidification component 300 closed, the outdoor fresh air circulating in the first air duct 110 is no longer humidified. When the first heat exchanger 210 is performing cooling and dehumidification, the temperature of the outdoor fresh air circulating in the first air duct 110 can be reduced to the dew point temperature, thereby achieving a dehumidification effect. Finally, the dehumidified outdoor fresh air enters the room through the indoor air outlet 112.

[0065] Optionally, the air conditioning equipment has an internal circulation humidification mode, which corresponds to: the indoor return air vent 121 is open, the connecting port 122 is open and the fresh air inlet 111 is closed, the humidification component 300 humidifies, and the first heat exchanger 210 is closed or operates in heating mode.

[0066] In this embodiment, with the fresh air inlet 111 closed, outdoor fresh air cannot enter the first air duct 110 through the fresh air inlet 111. With the indoor return air vent 121 and the connecting port 122 open, indoor air can enter the first air duct 110 through the second air duct 120. When the humidification component 300 is humidifying, the indoor air circulating in the first air duct 110 can be humidified. When the first heat exchanger 210 is closed, the temperature of the indoor air circulating in the first air duct 110 is not affected. When the first heat exchanger 210 is operating in heating mode, the temperature of the indoor air circulating in the first air duct 110 can be increased, thereby increasing the moisture absorption capacity of the indoor air and improving the humidification effect. Finally, the humidified indoor air returns to the room through the indoor air outlet 112.

[0067] Optionally, the air conditioning equipment has an internal circulation dehumidification mode, which corresponds to: the indoor return air vent 121 is open, the connecting port 122 is open and the fresh air inlet 111 is closed, the humidification component 300 is closed, and the first heat exchanger 210 performs cooling dehumidification.

[0068] In this embodiment, with the fresh air inlet 111 closed, outdoor fresh air cannot enter the first air duct 110 through the fresh air inlet 111. With the indoor return air vent 121 and the connecting port 122 open, indoor air can enter the first air duct 110 through the second air duct 120. With the humidification component 300 closed, the indoor air circulating in the first air duct 110 is no longer humidified. When the first heat exchanger 210 is performing cooling and dehumidification, the temperature of the indoor air circulating in the first air duct 110 can be reduced to the dew point temperature, thereby achieving a dehumidification effect. Finally, the dehumidified indoor air returns to the room through the indoor air outlet 112.

[0069] Optionally, the air conditioning equipment has a mixed air humidification mode, which corresponds to: the indoor return air vent 121 is open, the connecting port 122 is open and the fresh air inlet 111 is open, the humidification component 300 humidifies, and the first heat exchanger 210 is closed or operates in heating mode.

[0070] In this embodiment, with the fresh air inlet 111 open, outdoor fresh air enters the first air duct 110 through the fresh air inlet 111. With the indoor return air vent 121 and the connecting port 122 open, indoor air enters the first air duct 110 through the second air duct 120, thereby forming a mixed airflow between the indoor air and the outdoor fresh air. When the humidification component 300 is humidifying, the mixed airflow flowing within the first air duct 110 can be humidified. When the first heat exchanger 210 is closed, the temperature of the mixed airflow flowing within the first air duct 110 is not affected. When the first heat exchanger 210 is operating in heating mode, the temperature of the mixed airflow flowing within the first air duct 110 can be increased, thereby enhancing the moisture absorption capacity of the mixed air and improving the humidification effect. Finally, the humidified mixed air enters the room from the indoor air outlet 112.

[0071] Optionally, the air conditioning equipment has a mixed air dehumidification mode, which corresponds to: the indoor return air vent 121 is open, the connecting port 122 is open and the fresh air inlet 111 is open, the humidification component 300 is closed, and the first heat exchanger 210 performs cooling dehumidification.

[0072] In this embodiment, with the fresh air inlet 111 open, outdoor fresh air enters the first air duct 110 through the fresh air inlet 111. With the indoor return air vent 121 and the connecting port 122 open, indoor air enters the first air duct 110 through the second air duct 120, thereby forming a mixed airflow between the indoor air and the outdoor fresh air. With the humidification component 300 closed, the mixed air flowing in the first air duct 110 is no longer humidified. When the first heat exchanger 210 is performing cooling and dehumidification, the temperature of the mixed air flowing in the first air duct 110 can be reduced to the dew point temperature, thereby achieving a dehumidification effect. Finally, the dehumidified mixed air enters the room from the indoor air outlet 112.

[0073] Optionally, the indoor unit 100 includes a first side panel and a second side panel opposite to each other. A fresh air inlet 111 is located on the first side panel, and an indoor air outlet 112 and an indoor return air outlet 121 are located on the second side panel. The distance between the indoor air outlet 112 and the indoor return air outlet 121 is a first spacing, and the distance between the first side panel and the second side panel is a second spacing, with the ratio of the first spacing to the second spacing ranging from 0.2 to 0.4.

[0074] Optionally, the air conditioning equipment also includes an outdoor unit, and the heat exchange assembly 200 further includes a second heat exchanger and a compressor. The second heat exchanger is located in the outdoor unit and is connected to the first heat exchanger 210 via a throttling device. The compressor is located in the outdoor unit and is connected to both the first heat exchanger 210 and the second heat exchanger via a four-way reversing valve. The compressor, the first heat exchanger 210, and the second heat exchanger constitute an air conditioning circulation system.

[0075] In this embodiment, the air conditioning circulation system has a first refrigerant flow direction and a second refrigerant flow direction. The first refrigerant flow direction consists of: compressor, four-way reversing valve, first heat exchanger 210, throttling device, and second heat exchanger. Under the first refrigerant flow direction, the first heat exchanger 210 acts as a condenser for heating. The second refrigerant flow direction consists of: compressor, four-way reversing valve, second heat exchanger, throttling device, and first heat exchanger 210. Under the second refrigerant flow direction, the first heat exchanger 210 acts as an evaporator for cooling.

[0076] Optionally, such as Figure 3 As shown, the humidification assembly 300 includes a water tank 310 and a water jet 320. The water tank 310 is used to store humidification water. The water jet 320 is disposed in the water tank 310, and when it rotates, it can drive the humidification water to follow and swing, so that the air flowing through the water jet 320 is humidified.

[0077] In this embodiment, the water jet 320 is partially located inside the water tank 310 and partially located outside the water tank 310. The portion inside the water tank 310 facilitates water splashing, while the portion outside the water tank 310 facilitates contact with the airflow within the first air duct 110. When the water jet 320 rotates, it causes the humidifying water to follow and be splashed. At this time, the airflow passing through the water jet 320 can be effectively humidified.

[0078] Optionally, such as Figure 3 As shown, the fan assembly 400 includes a centrifugal fan 410, the axis of which is arranged perpendicular to the base plate of the indoor unit 100. This helps to reduce the thickness of the indoor unit 100.

[0079] Optionally, the air conditioning equipment also includes an auxiliary heating component 500, which is used to assist in heating the air flowing through the first air duct 110. For example... Figure 3 and Figure 4 As shown, the auxiliary heating component 500 includes an electric heating element 510, which is disposed in the first air duct 110 and is located between the heat exchange component 200 and the humidification component 300 along the gas flow direction.

[0080] In this embodiment, when the heating element 510 is powered on, it radiates heat to the air within the first air duct 110. In the fresh air humidification mode, internal circulation humidification mode, or mixed air humidification mode, activating the heating element 510 assists the first heat exchanger 210 in raising the temperature of the air flowing through the first air duct 110, thereby enhancing the humidification effect. In the fresh air dehumidification mode, internal circulation dehumidification mode, or mixed air dehumidification mode, since the first heat exchanger 210 performs cooling dehumidification, resulting in a lower air temperature after dehumidification, activating the heating element 510 at this time heats the dehumidified air, achieving a dehumidification and reheating effect.

[0081] Optionally, such as Figure 4 As shown, the fresh air inlet 111 is equipped with a controllable switch first damper 1111, and the connecting port 122 is equipped with a controllable switch second damper 1221. The air conditioning equipment also includes a controller, which is electrically connected to the first damper 1111, the second damper 1221, and the fan assembly 400.

[0082] In this embodiment, the controller can control the opening and closing state of the first damper 1111. When the first damper 1111 is open, outdoor fresh air can enter the first air duct 110 through the fresh air inlet 111. The controller can also control the opening and closing state of the second damper 1221. When the second damper 1221 is open, air from the second air duct 120 can enter the first air duct 110 through the connecting port 122. The controller can also control the start and stop state of the fan assembly 400. When the fan assembly 400 is started, it promotes the air in the first air duct 110 to be blown into the room from the indoor air outlet 112.

[0083] Optionally, in the case of mode switching, the controller is configured to: first control the fan assembly 400 to stop and both the first damper 1111 and the second damper 1221 to close; then, after a first time, control the first damper 1111 and the second damper 1221 to switch to the on / off state of the corresponding mode; and finally, after a second time, control the fan assembly 400 to start.

[0084] In this embodiment, when switching modes, such as from fresh air humidification mode to internal circulation humidification mode, the controller first shuts down the fan assembly 400 and closes both the first damper 1111 and the second damper 1221. After a first time, the controller opens the second damper 1221. After a second time, the controller starts the fan assembly 400. Similarly, when switching from fresh air humidification mode to mixed air dehumidification mode, the controller first shuts down the fan assembly 400 and closes both the first damper 1111 and the second damper 1221. After a first time, the controller opens both the first damper 1111 and the second damper 1221. After a second time, the controller starts the fan assembly 400. This avoids sudden changes in local pressure caused by directly switching damper states, thus ensuring system stability during mode switching.

[0085] Optionally, the ratio of the first time to the second time can range from 2 to 4. This time ratio design provides sufficient time for damper control without making the switching time too long. For example, the first time can be 3 seconds and the second time can be 1 second.

[0086] Optionally, in the case of power-on reset or power-off reset, the controller is configured to: control the first damper 1111 to close, and control the second damper 1221 to close first and then open. This helps prevent outdoor air from entering the indoor unit 100 during reset when the first damper 1111 is closed. The second damper 1221 closing first and then opening helps to create a stable pressure difference between the inside and outside of the indoor unit 100.
