Therefore, the temperature and humidity control of air conditioning is crucial to ensure the normal operation of the equipment.

[0003] When adjusting the temperature and humidity of the air conditioner, when the humidity is too high, the air conditioner will start the dehumidification function, usually by cooling the coil to lower the air temperature, so that the water vapor in the air condenses into water droplets and is discharged, thereby reducing the humidity. At the same time, the air volume and wind speed of the air conditioner fan can be adjusted to achieve the dehumidification effect; if the humidity is too low, the computer room air conditioner will perform humidification operations. Common humidification methods include steam humidification and ultrasonic humidification.

[0022] Reference Figure 1 As shown, Figure 1 A schematic diagram of the structure of an air conditioning device provided in an embodiment of the present application. This embodiment discloses an air conditioning device, which includes a cabinet 1, a temperature adjustment component 2, a fan component 3, a bypass air duct 4 and a humidity adjustment component 5. The cabinet 1 is provided with an air inlet 11, an air outlet 12 and a receiving chamber 13, and the air inlet 11, the air outlet 12 and the receiving chamber 13 are connected respectively. The temperature adjustment component 2 is arranged in the receiving chamber 13, and is used to adjust the temperature of the air in the receiving chamber 13. The fan component 3 includes a partition 31 and a fan 32, the partition 31 is arranged in the receiving chamber 13 and divides the receiving chamber 13 into a positive pressure area 130 and a negative pressure area 131, and the fan 32 is installed on the partition 31, and the fan 32 is used to transport the air entering from the air inlet 11 from the negative pressure area 131 to the positive pressure area 130 and output from the air outlet 12 after the temperature is adjusted by the temperature adjustment component 2. The bypass air duct 4 is connected to the positive pressure area 130 and the negative pressure area 131 respectively, so that part of the air delivered to the positive pressure area 130 can flow through the bypass air duct 4 and then flow back to the negative pressure area 131. The humidity adjustment component 5 is arranged in the bypass air duct 4 to adjust the humidity of the air in the bypass air duct 4.

[0023] In this embodiment, two fans 32 are provided, and the two fans 32 are spaced apart along the length direction of the partition 31 to increase the air flow rate, thereby improving the working efficiency of the air-conditioning device. It can be understood that in other embodiments, there may be only one, three, or more fans 32.

[0024] The fan assembly 3 of this embodiment is used to transport the air entering from the air inlet 11 from the negative pressure zone 131 to the positive pressure zone 130 and output it from the air outlet 12 after the temperature is adjusted by the temperature adjustment assembly 2. This embodiment is provided with a bypass air duct 4, which is connected to the positive pressure zone 130 and the negative pressure zone 131 respectively. By making a certain pressure difference between the air inlet and the air outlet of the bypass air duct 4, part of the air transported to the positive pressure zone 130 can flow through the bypass air duct 4 and then flow back to the negative pressure zone 131. The humidity adjustment assembly 5 is arranged in the bypass air duct 4, which is used to adjust the humidity of the air in the bypass air duct 4, so that the air after the humidity is adjusted is mixed with the new air entering from the air inlet 11, and is output from the air outlet 12 after the temperature is adjusted by the temperature adjustment assembly 2, so as to realize the synchronous adjustment of the air-conditioning temperature and humidity. By adjusting the temperature and humidity of the air separately, the situation where the output temperature of the air-conditioning is affected by adjusting the humidity of the air-conditioning is reduced, thereby improving the working efficiency of the air-conditioning device.

[0025] Continue to refer to Figure 1 As shown, the bypass air duct 4 is provided with an air inlet end 41 and an air outlet end 42, and the air inlet end 41 is connected to the positive pressure zone 130. The air outlet end 42 is connected to the negative pressure zone 131. The humidity adjustment component 5 includes a humidifier 51, a first coil 52 and a first heater 53, and the humidifier 51, the first coil 52 and the first heater 53 are respectively arranged in the bypass air duct 4. The humidifier 51 is used to increase the humidity of the air in the bypass air duct 4. When the air humidity at the air outlet 12 is low, the humidifier 51 converts water into water vapor and transports it to the air, thereby increasing the moisture content in the air and keeping the air moist. The first coil 52 is used to use a cooling medium (such as a coolant or a refrigerant) to reduce the temperature of the air in the bypass air duct 4. The first heater 53 is used to increase the temperature of the air in the bypass air duct 4, and the first heater 53 adjusts the temperature of the air outlet end 42 to be close to the temperature of the accommodating chamber 13.

[0026] In this embodiment, the air inlet end 41 is located at one end of the positive pressure area 130 close to the negative pressure area 131 to reduce the situation where the air circulation path in the bypass air duct 4 is too long, resulting in reduced air circulation efficiency, thereby ensuring the normal operation of the air conditioning device. The air outlet end 42 is located at one end of the negative pressure area 131 away from the positive pressure area 130, so that the air after humidity adjustment can be mixed with the new air entering from the air inlet 11, and the temperature is adjusted by the temperature adjustment component 2 before being output from the air outlet 12.

[0027] In this embodiment, the air inlet end 41 and the air outlet end 42 are located on the same side of the cabinet 1 to reduce the situation where the air circulation path in the bypass air duct 4 is too long, resulting in a decrease in air circulation efficiency, thereby ensuring the normal operation of the air-conditioning device. It can be understood that in other embodiments, the air inlet end 41 and the air outlet end 42 can also be located on different sides of the cabinet 1.

[0028] Reference Figure 1 As shown, in the bypass air duct 4, along the direction from the air inlet end 41 to the air outlet end 42, the humidifier 51 is located on the side of the first coil 52 facing the air inlet end 41, and the first heater 53 is located on the side of the first coil 52 facing away from the air inlet end 41. The air entering the bypass air duct 4 from the air inlet end 41 is first humidified by the humidifier 51 and then dehumidified by the first coil 52, thereby achieving the effect of adjusting the humidity.

[0029] Reference Figure 2 As shown, Figure 2 A schematic diagram of the structure of the first embodiment of the air conditioning device provided in the embodiment of the present application. In one embodiment, in the bypass air duct 4, along the direction from the air inlet end 41 to the air outlet end 42, the first coil 52 is located on the side of the humidifier 51 facing the air inlet end 41, and the first heater 53 is located on the side of the humidifier 51 facing away from the air inlet end 41. The air entering the bypass air duct 4 from the air inlet end 41 is first dehumidified by the first coil 52 and then humidified by the humidifier 51, thereby achieving the effect of adjusting the humidity.

[0030] Reference Figure 1 As shown, the temperature adjustment component 2 includes a second coil 21 and a second heater 22, which are respectively arranged in the accommodating cavity 13, and the second coil 21 is located at the input end of the fan 32, and the second heater 22 is located at the output end of the fan 32. The second coil 21 is used to reduce the temperature of the air in the accommodating cavity 13 by using a cooling medium (such as a coolant or a gaseous refrigerant), or to increase the temperature of the air in the accommodating cavity 13 by using a heating medium, and the second heater 22 is used to increase the temperature of the air in the accommodating cavity 13, thereby achieving temperature adjustment.

[0031] In the present embodiment, the second coil 21 is configured as a V-shaped coil. The V-shaped coil has a simple structure and is convenient for maintenance and installation. When the cooling medium flows in the second coil 21, the wind speed can be evenly distributed on the windward and leeward sides of the V-shaped coil. Compared with the straight coil that can also perform heat exchange, the V-shaped coil can improve the heat exchange efficiency of the second coil 21, thereby improving the working efficiency of the air-conditioning device, and reducing the phenomenon of local overheating or overcooling of the second coil 21, thereby extending the service life of the second coil 21 and reducing the cost. It can be understood that in other embodiments, the second coil 21 can also be other structures, such as a U-shaped coil.

[0032] Reference Figure 3 As shown, Figure 3 A schematic diagram of the structure of the second embodiment of the air conditioning device provided in the embodiment of the present application. A plurality of second heaters 22 are provided, and the plurality of second heaters 22 are respectively arranged at the output end of the fan 32 and spaced apart along the first direction of the cabinet 1. Figure 3In the X direction, the temperature accuracy of the air-conditioning device is improved, thereby improving the working efficiency of the air-conditioning device. The specific number of the second heaters 22 can be set as needed and is not limited here.

[0033] The temperature adjustment component 2 also includes a third heater 23, which is arranged in the accommodating cavity 13 and located between the fan 32 and the second coil 21, and is used to increase the temperature of the air in the accommodating cavity 13 to achieve the efficiency of multi-stage controlled heating, further improve the regulation of the air conditioning temperature accuracy, and thus improve the working efficiency of the air conditioning device.

[0034] In a specific application scenario, when working, the air entering from the air inlet 11 is transported from the negative pressure area 131 to the positive pressure area 130 through the fan 32 and output from the air outlet 12. During the transportation process, the temperature of the air in the accommodating chamber is adjusted by the temperature of the second coil 21, the power of the second heater 22 and the speed of the fan 32. When the temperature of the air in the accommodating chamber needs to be increased, the second heater 22 is turned on to heat the air in the accommodating chamber to increase the temperature of the air in the accommodating chamber. When the temperature of the air in the accommodating chamber needs to be lowered, the air in the accommodating chamber is cooled by the cooling medium in the second coil. Heat exchange is performed to reduce the temperature of the air in the accommodating chamber; wherein, part of the air delivered to the positive pressure zone 130 will enter the bypass air duct 4 through the air inlet end 41, and in the bypass air duct 4, the air is humidified by the humidifier 51 and the first coil 52. When the air needs to be humidified, the humidifier 51 is turned on to increase the humidity of the air in the bypass air duct 4. When the humidity of the air needs to be reduced, the temperature of the first coil 52 is adjusted, and the water is cooled and discharged to reduce the humidity of the air in the bypass air duct 4. The air after humidity adjustment returns to the accommodating chamber 13 from the air outlet end 42, thereby realizing synchronous adjustment of the air-conditioning temperature and humidity.

[0035] The above is only a preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
