Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a damper assembly, an air conditioner and a dehumidification method thereof. Background Art

[0002] When an air-conditioning unit operates in an environment with high air humidity, condensation and water blowing are prone to occur in the air supply section. Under the action of the fan, the condensed water is blown out of the water receiving tray, resulting in water accumulation inside the air-conditioning unit. There is a hidden danger that the motor, fan, etc. may come into contact with water, affecting the performance of the air-conditioning unit and even increasing the probability of failure of the air-conditioning unit. In order to avoid condensation and water blowing, the current solution is to dehumidify the air inside the unit and add a water baffle to the evaporator to prevent the condensed water generated during the cooling of the evaporator from being blown away. However, due to the high humidity of the air inside the air-conditioning unit, the current solution cannot completely prevent the water blowing phenomenon from occurring in the air supply section inside the air-conditioning unit. In addition, in order to prevent condensation from occurring during the operation of the air-conditioning unit, the pipes, liquid distribution pipes and gas collecting pipes inside the air-conditioning unit need to be cotton-wrapped. However, the applicant found that after the liquid distribution pipe was cotton-wrapped, it blocked the wind and was not aesthetically pleasing.

[0003] The air volume regulating valve is referred to as the air valve for short. The air valve is an indispensable terminal accessory in the ventilation, air conditioning and air purification projects of industrial plants and civil buildings. The air valve is generally used in the pipes of air conditioning and ventilation systems to adjust the air volume of the branch pipes. It can also be used for mixing and adjusting the fresh air and return air. It is one of the key devices for controlling the ventilation mode in various environments. The existing air valve assembly includes a plurality of rotatable window pieces, and the air valve assembly can be opened or closed by rotating the window pieces. The existing window pieces are generally solid structures, and when in use, they are only used for air volume regulation. Since the air valve is the only way for air to enter the interior of the unit, it is of great significance to provide an air valve assembly that can be used to dehumidify the air and dehumidify the air while it enters the interior of the unit.

[0037] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0038] The following is attached with the instruction manual Figures 1 to 8 And embodiments 1 to 3 describe the air valve assembly, air conditioner and dehumidification method of the present invention in detail.

[0039] Example 1

[0040] This embodiment describes the air valve assembly of the present invention in detail.

[0041] The air valve assembly of this embodiment includes a window 11 and a refrigerant pipe 12. Figure 3 As shown. Preferably, the window 11 has an open state in which the air duct is opened and a closed state in which the air duct is closed. The refrigerant pipeline 12 is provided at the window 11, and the refrigerant pipeline 12 is connected to the refrigerant circuit of the unit. More preferably, the air duct can be opened by rotating the window 11 to facilitate air supply to the unit; the air duct can also be closed by rotating the window 11 to stop air supply to the unit; and the air supply volume can also be controlled by controlling the rotation angle of the window 11. The unit of this embodiment refers to an air-conditioning unit, for example. The refrigerant pipeline 12 is connected to the refrigerant circuit of the unit, so that the refrigerant of the unit can flow through the window 11. When the unit is in cooling mode, the window 11 can be cooled by the refrigerant flowing through the window 11; when the unit is in heating mode, the window 11 can be heated by the refrigerant flowing through the window 11.

[0042] The air valve assembly of this embodiment includes a window 11 and a refrigerant pipe 12. The window 11 has an open state for opening the air duct and a closed state for closing the air duct. By opening and closing the window 11, the function of supplying air to the unit or the function of shutting off the air supply to the unit can be realized. On the other hand, since the refrigerant pipe 12 is provided at the window 11 and the refrigerant pipe 12 is connected to the refrigerant circuit of the unit, when the unit is in cooling mode, the refrigerant in the refrigerant circuit can flow through the refrigerant pipe 12 and cool the window 11. When the air enters the unit through the window 11, the moisture in the air condenses into water droplets when it is cold, thereby dehumidifying the air sent into the unit, ensuring the dryness of the air sent into the unit, and avoiding condensation and water blowing inside the unit. That is, the air valve assembly of this embodiment solves the technical problem of how to dehumidify the air as it enters the unit.

[0043] In addition, when the unit is in heating mode, the air valve assembly of this embodiment can allow the refrigerant in the refrigerant circuit to flow through the refrigerant pipe 12 and heat the window 11. When the air enters the unit through the window 11, the air is heated by the window 11, so that the air valve assembly of this embodiment can be used as an auxiliary heating device.

[0044] According to a preferred embodiment, the interior of the window 11 is a hollow structure, and the refrigerant pipe 12 is installed in the hollow structure. Figure 1 、 Figure 3 and Figure 4 As shown. The air valve assembly of the preferred technical solution of this embodiment installs the refrigerant pipe 12 in the hollow structure inside the window slat 11, so that the refrigerant flowing through the refrigerant pipe 12 can simultaneously cool the upper and lower surfaces of the window slat 11, thereby enhancing the cooling effect of the refrigerant on the window slat 11, thereby enhancing the dehumidification effect of the air valve assembly on the air sent into the unit, ensuring the dryness of the air sent into the unit, and avoiding condensation and water blowing inside the unit. On the other hand, installing the refrigerant pipe 12 in the hollow structure inside the window slat 11 can also avoid the problem of setting the refrigerant pipe 12 on the surface of the window slat 11 for a long time, which will cause dust to collect on the surface of the refrigerant pipe 12 and affect the cooling effect on the window slat 11.

[0045] According to a preferred embodiment, the window 11 is a wave-shaped structure, and a groove 111 is formed between two adjacent protrusions of the wave-shaped structure. The groove 111 is used to collect condensed water generated at the window 11. Figures 1 to 4 As shown. The air valve assembly of the preferred technical solution of this embodiment has a groove 111 formed on the surface of the window 11. When air enters the unit through the window 11, the moisture in the air condenses into condensed water when it is cold. Under the action of the wind force of the unit's inlet, the dehumidified dry air enters the unit. The condensed water condensed on the window 11 is blown into the groove 111 for collection, so that the collected condensed water can be discharged. On the other hand, the blocking effect of the protrusions on both sides of the groove 111 can prevent the condensed water from being blown into the unit and affecting the air humidity in the unit. In addition, a large space is formed between the two opposing protrusions on the upper and lower surfaces of the window 11. The refrigerant pipeline 12 can be installed in this space to enhance the cooling effect of the window 11.

[0046] According to a preferred embodiment, the air valve assembly further includes a fixing plate 13, such as Figure 5 As shown. Preferably, the window 11 is rotatably connected to the fixed plate 13. In the air valve assembly of the preferred technical solution of this embodiment, the window 11 is rotatably connected to the fixed plate 13, thereby enabling the rotation of the window 11, and the rotation of the window 11 can open, close or control the air duct.

[0047] Preferably, a mounting hole is provided on the fixing plate 13, and a connecting piece 14 is provided in the window 11. One end of the connecting piece 14 is rotatably installed in the mounting hole, and one end of the connecting piece 14 is connected to the refrigerant circuit of the unit, and the other end of the connecting piece 14 is connected to the refrigerant pipeline 12. Figure 4 As shown. More preferably, the connecting piece 14 has an interface at one end and at least one interface at the other end. For example, when there are two refrigerant pipes 12 arranged in parallel in the window 11, the connecting piece 14 is a tee, and the first interface of the tee can be rotatably installed in the mounting hole, and the first interface is connected to the refrigerant circuit of the unit through the pipeline; the other two interfaces of the tee are respectively connected to one end of the two refrigerant pipes 12 arranged in parallel. In the air valve assembly of the preferred technical solution of this embodiment, a connecting piece 14 is provided in the window 11, and the connecting piece 14 can not only realize the rotatable connection between the window 11 and the fixed plate 13, but also realize the connection between at least two refrigerant pipes 12 arranged in parallel and the refrigerant circuit of the unit.

[0048] Preferably, a drainage channel 131 is provided on the fixing plate 13, and the drainage channel 131 is communicated with the groove 111, and the drainage channel 131 is also communicated with the external environment of the unit, such as Figure 5 As shown. More preferably, the number of drainage channels 131 is one or more. In the damper assembly of the preferred technical solution of this embodiment, the fixed plate 13 is provided with a drainage channel 131, which allows the condensate collected in the groove 111 to flow along the groove 111 to the drainage channel 131 under the action of its own weight. The condensate is then discharged from the unit through the drainage channel 131, preventing water accumulation in the damper assembly.

[0049] According to a preferred embodiment, the air valve assembly further includes a control valve 15, such as Figure 6 As shown. Preferably, the control valve 15 is located between the refrigerant pipeline 12 and the refrigerant circuit of the unit, and the control valve 15 has a first state in which the refrigerant pipeline 12 is connected to the refrigerant circuit of the unit, and a second state in which the refrigerant pipeline 12 is disconnected from the refrigerant circuit of the unit. More preferably, the control valve 15 is, for example, an electromagnetic ball valve. The air valve assembly of the preferred technical solution of this embodiment, by providing the control valve 15, can enable the air valve assembly to determine the connectivity state of the refrigerant pipeline 12 based on actual needs. Specifically, when the air humidity in the environment is low, for example, less than 30%, there is no need to dehumidify the air. At this time, the refrigerant pipeline 12 can be disconnected from the refrigerant circuit of the unit through the control valve 15 to avoid affecting the cooling effect of the unit.

[0050] According to a preferred embodiment, the air valve assembly further includes a humidity sensor 16 and a controller 17. Figure 6As shown. Preferably, the humidity sensor 16 is used to detect the air humidity in the environment, and the control valve 15 and the humidity sensor 16 are both connected to the controller 17, and the controller 17 controls the control valve 15 to be in the first state or the second state based on the detection result of the humidity sensor 16. More preferably, the humidity sensor 16 is arranged at the condenser 22 of the unit. The air valve assembly of the preferred technical solution of this embodiment is provided with a humidity sensor 16 and a controller 17, and the controller 17 controls the control valve 15 to be in the first state or the second state based on the detection result of the humidity sensor 16, so that when the air humidity in the environment reaches a preset value, the refrigerant pipeline 12 can be connected to the refrigerant circuit of the unit to cool the window 11, and the air enters the unit through the window 11 while dehumidifying the air sent to the unit; when the air humidity in the environment does not reach the preset value, the refrigerant pipeline 12 is disconnected from the refrigerant circuit of the unit to avoid affecting the cooling effect of the unit.

[0051] Example 2

[0052] This embodiment describes the air conditioner of the present invention in detail.

[0053] The air conditioner of this embodiment includes a unit and a damper assembly. Preferably, the damper assembly is the damper assembly of any one of the technical solutions in Example 1, and the damper assembly is arranged at the air inlet section of the unit, such as Figure 6 As shown. Preferably, the structure, cooling and heating principles of the unit are the same as those of the prior art and will not be described in detail here. Specifically, the refrigerant circuit of the unit is formed by connecting the evaporator 21, the condenser 22, the compressor 23 and the evaporator 21 in sequence, as shown in FIG. Figure 6 shown.

[0054] The air conditioner of this embodiment includes the air valve assembly of any one of the technical solutions in Example 1, and the air valve assembly is arranged at the air inlet section of the unit. When the unit is in cooling mode, the air valve assembly can dehumidify the air while supplying air, thereby ensuring the dryness of the air supplied to the unit and avoiding condensation and water blowing inside the unit, thereby ensuring the performance and reliability of the unit. At the same time, it can also avoid cotton wrapping of the pipes, liquid distribution pipes and gas collecting pipes inside the air-conditioning unit, which not only avoids the wind blocking phenomenon caused by cotton wrapping, but also reduces the distance between pipes, thereby saving unit space and reducing the size of the unit.

[0055] Example 3

[0056] This embodiment describes in detail the dehumidification method of the air conditioner of the present invention.

[0057] Figure 7 FIG. 1 shows a flow chart of the dehumidification method of the air conditioner of this embodiment. Figure 7As shown, the dehumidification method for an air conditioner according to any one of the technical solutions in Example 2 comprises the following steps:

[0058] Step 1: Get the air humidity in the environment.

[0059] Step 2: Compare the acquired air humidity with the preset air humidity.

[0060] Step 3: When the acquired air humidity exceeds the preset air humidity, the refrigerant pipeline 12 is controlled to be connected to the refrigerant circuit of the unit.

[0061] In the dehumidification method for an air conditioner according to any of the technical solutions in Example 2, when the unit is in cooling mode (generally, dehumidification of the air is only required when the unit is in cooling mode), when the acquired air humidity exceeds the preset air humidity, the refrigerant pipe 12 is controlled to be connected to the refrigerant circuit of the unit, so that the refrigerant in the refrigerant circuit can flow through the refrigerant pipe 12 and cool the window. When the air enters the unit through the window, the moisture in the air condenses into water droplets when it is cold, thereby dehumidifying the air sent into the unit, ensuring the dryness of the air sent into the unit, and avoiding condensation and water blowing inside the unit.

[0062] Preferably, the preset air humidity is 30%. The air humidity in the environment is generally 30% to 70%. The dehumidification method of the preferred technical solution of this embodiment starts dehumidification when the air humidity in the environment reaches the minimum critical humidity to ensure that the air inside the unit is absolutely dry.

[0063] Figure 8 A flow chart of another preferred embodiment of the dehumidification method of the air conditioner of this embodiment is shown. Figure 8 As shown:

[0064] The humidity sensor 16 detects the humidity of the air in the environment. When the humidity of the air in the environment does not reach 30%, the humidity sensor 16 continues to detect the humidity of the air in the environment until the humidity of the air in the environment reaches 30%.

[0065] When the air humidity in the environment reaches 30%, the humidity sensor 16 will send a signal to the controller 17. The controller 17 controls the control valve 15 to open, and the refrigerant pipeline 12 of the air valve assembly is connected to the refrigerant circuit of the unit. The air valve assembly turns on the cooling mode, and the temperature of the window 11 decreases. When the air drawn into the unit reaches the refrigerated window 11, the water vapor in the air condenses into water droplets when it is cold. Under the action of the wind force of the unit's intake air, the dry air that has been dehumidified will enter the unit, and the water droplets condensed on the window 11 will be blown into the groove 111. Under the action of their own weight, the condensed water droplets flow down along the groove 111 to the drainage channel 131 and are discharged from the unit.

[0066] During air conditioner operation, when the ambient humidity drops below 30%, humidity sensor 16 stops sending signals to controller 17, controlling valve 15 closes, disconnecting refrigerant line 12 of the damper assembly from the unit's refrigerant circuit, and the damper assembly stops cooling. If humidity sensor 16 detects that the ambient humidity is still above 30%, the damper assembly resumes cooling, maintaining a relatively low temperature for window slats 11 to continue dehumidification.

[0067] When the air conditioner is in heating mode, the air entering the unit can be auxiliary heated. Specifically, the method of the air valve assembly to auxiliary heat the air is the same as the method of cooling the window 11, which will not be repeated here.
