[0020] The preferred embodiments of the present application will be described below with reference to the accompanying drawings.

[0021] Example 1

[0022] Embodiment 1 of the present application provides a control method for a humidity control system. The humidity control system includes a water inlet module, a humidification module, and a second valve. The water inlet module includes a water tank and a first valve arranged on the water inlet side of the water tank. The humidification module is connected to the water tank to humidify the introduced air. The second valve is arranged on the water outlet side of at least one of the water tank and the humidification module.

[0023] Figure 1 Schematic diagram of a control method of a humidity control system according to an embodiment of the present application. Figure 1 As shown, the method includes:

[0024] Step 101: Detecting the water level in the water tank when the first valve and the second valve are set to a preset state;

[0025] Step 102, determining the operating state of the humidity control system according to the water level detection result.

[0026] According to the above embodiment, by setting the first valve on the water inlet side of the water tank and the second valve on the water outlet side of the water tank and / or the humidification module to a preset state, the water level in the water tank is detected, and the operating state of the humidity control system is determined based on the water level detection result. The humidity control system can be detected in a simple way, thereby improving the convenience of detection.

[0027] For example, according to the above embodiment, when the water circuit of the humidity control system adopts a hidden design, it is not necessary to open the housing of the humidity control system to inspect the water circuit. It is only necessary to set the valve of the humidity control system to a preset state and detect the water level in the water tank, and then it can be determined whether the humidity control system has a fault according to the water level detection result. Therefore, the humidity control system can be easily inspected.

[0028] In some embodiments, the control method of the humidity control system can be executed in the trial operation mode. For example, a newly installed humidity control system or a humidity control system that has not been used for a long time can enter the trial operation mode according to the information input by the user, and execute the control method of the embodiment of the present application in the trial operation mode. Thus, it is possible to detect whether there is an abnormality in the humidity control system, which is conducive to subsequent repair and maintenance, and it is possible to avoid abnormal detection in the normal operation mode of the humidity control system and adversely affect the user experience. In addition, the humidity control system can also automatically enter the trial operation mode when the preset conditions are met, and execute the control method of the embodiment of the present application in the trial operation mode. For example, when the humidity control system has an abnormal operation, or the cumulative use time of the humidity control system reaches a preset time length, it spontaneously enters the trial operation mode.

[0029] The control method of the embodiment of the present application can be applied to various humidity control systems. Figure 2 Schematic diagram of the structure of the humidity control system of the embodiment of the present application. Figure 2 In the figure, the pipes with arrows connecting modules or devices are air pipes; the solid lines between modules or devices represent refrigerant pipes; the dotted lines between modules or devices represent communication connections, which can be wired connections or wireless connections; and the dot-dash lines between modules or devices represent water routes.

[0030] like Figure 2 As shown, the humidity adjustment system 200 includes: a water inlet module 210 and a humidification module 220. The water inlet module 210 is connected to the humidification module 220 to supply water to the humidification module 220; the humidification module 220 adjusts the humidity of the introduced air.

[0031] Figure 3 FIG. 2 is a schematic diagram of a partial structure of a humidity control system 200 according to an embodiment of the present application. Figure 3 As shown, the water inlet module 210 of the humidity control system 200 may include a water tank 2101 and a first valve 2102, and the first valve 2102 is arranged at the water inlet side of the water tank 2101. When the first valve 2102 is opened, water is introduced into the water tank 2101 from the water inlet 240 of the humidity control system 200, and when the first valve 2102 is closed, water is not introduced into the water tank 2101 from the water inlet 240 of the humidity control system 200.

[0032] In some embodiments, the first valve 2102 may include various valves capable of controlling opening, closing, or opening size. For example, the first valve 2102 may include a solenoid valve, etc.

[0033] In some embodiments, Figure 3As shown, in the humidification module 220, the humidification unit 2201 can perform humidification based on a wet film. The water in the water tank 2101 flows into the wet film, and the wet film absorbs water to form a uniform water film. When dry air passes through the wet film, the water molecules fully absorb the heat in the air and vaporize and evaporate, thereby increasing the humidity of the air and forming humidified air. The present application is not limited to this, and the humidification unit 2201 can also be based on other humidification principles.

[0034] In some embodiments, Figure 3 As shown, the humidifying device 220 may further include a temperature regulating unit 2202. The temperature regulating unit 2202 is located at the upstream side of the humidifying unit 2201 and is used to regulate the temperature of the introduced air, such as heating it. The heated air is transported to the humidifying unit 2201, which can improve the humidification efficiency of the humidifying unit 2201.

[0035] For the temperature adjustment unit 2202 based on different principles, the way of adjusting the temperature may be different. Figure 3 As shown, the temperature control unit 2202 performs temperature control based on the heat exchange principle, and its temperature control capability can be adjusted by adjusting the opening of the valve 2203 (refrigerant valve) of the refrigerant pipeline in the heat exchange module. For another example, the temperature control unit 2202 performs temperature control based on the electric auxiliary heating principle, and its temperature control capability can be adjusted by adjusting the output power of the electric auxiliary heating element.

[0036] When the temperature adjustment unit 2202 adjusts the temperature based on the heat exchange principle, the humidification module 220 may further include a filter unit 2204. Before the refrigerant flows into the temperature adjustment unit 2202 via the refrigerant valve 2203, it first passes through the filter unit 2204 to filter out impurities in the refrigerant to avoid blocking the refrigerant pipeline and improve the heat exchange efficiency.

[0037] In some embodiments, Figure 3 As shown, the humidity adjustment system 200 may further include a second valve 211. The second valve 211 may be disposed at the drain outlet side of the water tank 2101.

[0038] The drain outlet of the water tank 2101 can be connected to the water inlet of the humidification module 220 (i.e., the water inlet of the humidification unit 2201). The second valve 211 can be arranged between the drain outlet of the water tank 2101 and the water inlet of the humidification unit 2201 to control the on-off of the water path between the drain outlet of the water tank 2101 and the water inlet of the humidification unit 2201. For example, the second valve 211 can be set to supply water from the water tank 2101 to the humidification module 220, so that the water tank 2101 is connected to the humidification unit 2201 and water is supplied to the humidification unit 2201; or, the second valve 211 can be set to close the water outlet of the water tank 2101, the water tank 2101 and the humidification unit 2201 are cut off, and the water supply to the humidification unit 2201 is stopped.

[0039] The drain outlet of the water tank 2101 may also be connected to the drain outlet 250 of the humidity control system 200. The second valve 211 may be disposed between the drain outlet of the water tank 2101 and the drain outlet 250 of the humidity control system 200 to control the on-off of the water path between the drain outlet of the water tank 2101 and the drain outlet 250 of the humidity control system 200. For example, the second valve 211 may be configured to drain water from the water tank 2101 to the drain outlet 250; or, the second valve 211 may be configured to close the water outlet of the water tank 2101, and the water tank 2101 does not drain water.

[0040] Among them, setting the second valve 211 to close the water outlet of the water tank 2101 may include: cutting off the water path between the water tank 2101 and the humidification module 220, and not supplying water to the humidification module 220; or, cutting off the water path between the water tank 2101 and the drain outlet 250, and not draining water to the drain outlet 250; or, cutting off the water path between the water tank 2101 and the humidification module 220 and cutting off the water path between the water tank 2101 and the drain outlet 250, and the water tank 2101 neither supplies water nor drains water.

[0041] In some embodiments, the second valve 211 may also be disposed on the drain side of the humidification module 220. For example, the second valve 211 may be disposed between the drain of the humidification module 220 and the drain 250 of the humidity control system 200. When the second valve 211 is opened, the humidification module 220 drains water to the drain 250, and when the second valve 211 is closed, the humidification module 220 does not drain water.

[0042] In some embodiments, the second valve 211 may be disposed at the drain side of the water tank 2101 and the humidification module 220. Thus, the drainage of the water tank 2101 and / or the water supply to the humidification module 220 and the drainage of the humidification module 220 can be controlled by the second valve 211.

[0043] In some embodiments, the second valve 211 may be any valve capable of controlling opening, closing, or opening size. For example, the second valve 211 may be a three-way valve. Figure 3 As shown, when the second valve 211 is a three-way valve, its first port a can be connected to the drain outlet of the water tank 2101, the second port b can be connected to the water inlet of the humidification unit 2201 of the humidification module 220, and the third port c can be connected to the drain outlet 250 of the humidity adjustment system 200.

[0044] When the first port a is connected to the second port b, water is supplied from the water tank 2101 to the humidifying unit 2201. When the first port a is connected to the third port c, the water tank 2101 discharges water to the drain 250. When the second port b is connected to the third port c, the humidifying unit 2201 discharges water to the drain 250. Thus, the water path between the water tank 2101 and the humidifying module 220, the water path between the water tank 2101 and the drain 250, and the water path between the humidifying module 220 and the drain 250 can be controlled by one valve, which helps to reduce the components of the humidity control system 200 and simplify the internal structure of the humidity control system 200.

[0045] In some embodiments, Figure 3 As shown, the humidity control system 200 may further include a water level detection module 260. The water level detection module 260 is used to obtain water level information in the water tank 2101. The water level detection module 260 may be a module capable of detecting water level in various forms. For example, the water level detection module 260 may include at least one float switch for detecting the water level in the water tank 2101, thereby determining the water level in the water tank 2101 according to the change in the state of the at least one float switch.

[0046] Figure 4 Schematic diagram of the structure of the water tank, float switch, second valve and humidification unit of the embodiment of the present application. Figure 4 As shown, the water tank 2101 is connected to the humidifying unit 2201 , the second valve 211 controls the water path between the water tank 2101 and the humidifying unit 2201 , and the water level detection module 260 is disposed in the water tank 2101 for detecting the water level in the water tank 2101 .

[0047] like Figure 4 As shown, the water level detection module 260 may include a first float switch 261, a second float switch 262, and a third float switch 263. The first float switch 261, the second float switch 262, and the third float switch 263 are respectively used to detect the low water level, the middle water level, and the high water level of the water tank 2101, wherein the low water level is located below the middle water level, and the middle water level is located below the high water level. When the water level in the water tank 2101 reaches the low water level, the first float switch 261 switches state, when the water level in the water tank 2101 reaches the middle water level, the second float switch 262 switches state, and when the water level in the water tank 2101 reaches the high water level, the third float switch 263 switches state.

[0048] like Figure 4As shown, the first float switch 261 includes a switch assembly 2611 and a float 2612. When the water level is lower than the position where the float 2612 is located (e.g., low water level), the output state of the switch assembly 2611 is a first state, such as OFF; after the water level rises to the position where the float 2612 is located, the float 2612 separates from the switch assembly 2611 as the water level rises, and the output state of the switch assembly 2611 switches to a second state, such as ON.

[0049] The second float switch 262 and the third float switch 263 may share the same float 2622. When the water level is lower than the position of the float 2622 (e.g., the middle water level), the output state of the switch component 2621 of the second float switch 262 is the third state, such as OFF, and the output state of the switch component 2631 of the third float switch 263 is the fourth state, such as ON; after the water level rises to the position of the float 2622, the float 2622 separates from the switch component 2621 of the second float switch 262 as the water level rises, and the output state of the switch component 2621 of the second float switch 262 is switched to the fifth state, such as ON; when the float 2622 reaches the position of the switch component 2631 of the third float switch 263 as the water level rises (e.g., the high water level), the output state of the switch component 2631 of the third float switch 263 is switched to the sixth state, such as OFF.

[0050] The corresponding relationship between the output states of the first float switch 261 , the second float switch 262 and the third float switch 263 and the water level can be referred to Table 1.

[0051] Table 1 Correspondence between the output states of the first float switch 261, the second float switch 262 and the third float switch 263 and the water level:

[0052] First float switch 261 Second float switch 262 The third float switch 263 Water Level ON ON OFF High Water Level ON ON ON Medium water level ON OFF ON Low Water Level OFF OFF ON No water level detected

[0053] It should be noted that the present application is not limited thereto, and a combination of other output states of the first float switch 261 , the second float switch 262 , and the third float switch 263 may also be used to represent different water levels.

[0054] In some embodiments, Figure 2 As shown, the humidity adjustment system 200 further includes: an air supply module 230, which is disposed inside the humidification module or outside the humidification device to introduce air into the humidification module.

[0055] In some embodiments, in the case where the air supply module 230 is disposed outside the humidification module, the air supply module 230 is disposed on the upstream side of the humidification module, or the air supply module 230 is disposed on the downstream side of the humidification module.

[0056] For example, the air supply module 230 may be arranged in a fresh air processing device, a full heat exchange device, or a ventilation device, wherein the full heat exchange device may or may not have an internal circulation function, and the ventilation device may or may not have an internal circulation function.

[0057] In some embodiments, when the air supply module 230 is disposed inside the humidification module, the air supply module 230 may be a fan, etc. In the embodiments of the present application, "downstream side" refers to the downstream side in the air flow path, and "upstream side" refers to the upstream side in the air flow path.

[0058] In some embodiments, the humidity control system of the present application may control multiple indoor spaces, and the humidifier 220 supplies air to the multiple indoor spaces through multiple air pipes 270. Figure 2 In the figure, two indoor spaces (space 1 and space 2) are taken as an example for explanation, however, the embodiment of the present application is not limited to two spaces, and there may be more spaces and more air ducts are set for air supply.

[0059] In some embodiments, the indoor space that is the object of the humidity control system may include multiple areas, and the humidifier 220 supplies air to the multiple areas of the indoor space through multiple air ducts 270 .

[0060] In some embodiments, the air duct 270 is an air inlet duct, and each air duct 270 corresponds to a different indoor space, or corresponds to a different area of ​​the indoor space.

[0061] In some embodiments, Figure 2 As shown, an air duct 271 serving as a return air duct may also be provided to centrally return air to each indoor space or each area and discharge the air to the outdoors.

[0062] In the embodiment of the present application, the humidity control system 200 may be a commercial humidity control system or a household humidity control system.

[0063] In some embodiments, the humidity control system 200 may include at least one group of outdoor units 281 and at least one indoor unit 282 connected to each group of outdoor units 281. That is, the humidity control system 200 may include one or more groups of outdoor units 281, each group of outdoor units 281 includes at least one outdoor unit; for a group of outdoor units, the group of outdoor units is connected to at least one indoor unit.

[0064] For example, the humidity adjustment system 200 includes an outdoor unit and an indoor unit connected to the outdoor unit.

[0065] For example, the humidity adjustment system 200 includes an outdoor unit and at least two indoor units connected to the outdoor unit.

[0066] For example, the humidity adjustment system 200 includes at least two outdoor units and at least two indoor units connected to the at least two outdoor units.

[0067] For example, a group of outdoor units and at least one indoor unit connected to the group of outdoor units constitute a refrigerant system, or multiple groups of outdoor units and at least one indoor unit respectively connected to the multiple groups of outdoor units constitute multiple refrigerant systems. Thus, the humidity control system 200 may include one refrigerant system or multiple refrigerant systems.

[0068] In some embodiments, the outdoor unit and the indoor unit may be air conditioning equipment of various models, types, forms, and capacities. For example, the indoor unit may be in the form of four-sided air outlet, two-sided air outlet, duct unit, ground air outlet, or skirting air outlet; the outdoor unit may be in the form of single fan upper air outlet, double fan upper air outlet, single fan front air outlet, or double fan front air outlet.

[0069] In some embodiments, Figure 2 As shown, the humidity adjustment system 200 may further include a control module 290. The control module 290 may control the working state of each component, module, device or equipment in the humidity adjustment system 200.

[0070] In some embodiments, the control module 290 may include a controller, for example, the controller may be a centralized controller, a wired controller, a remote controller, an intelligent controller, etc. The controller may generate control instructions for various components in the humidity control system 200 according to information input by the user.

[0071] In some embodiments, the control module 290 may also include a gateway device that collects data from various components, modules, devices or equipment and generates control instructions for various components, modules, devices or equipment in the humidity control system 200 based on the data.

[0072] For example, the control module 290 can generate an instruction to make the humidity control system 200 enter the trial operation mode according to the instruction input by the user or the collected data, and execute the control method of the embodiment of the present application in the trial operation mode. Among them, the control module 290 can send the instruction to enter the trial operation mode to the air supply module 230, and the air supply module 230 sends the instruction to the humidification module 220 through the communication line; or the control module 290 can also send the instruction to enter the trial operation mode to the air supply module 230 and the humidification module 220.

[0073] In some embodiments, in step 102 of the control method, determining the operating state of the humidity control system may include: determining whether there is an abnormality in the internal water circuit of the humidity control system; or determining whether there is an abnormality in a water level detection module for detecting the water level of the humidity control system; or determining whether there is an abnormality in the internal water circuit of the humidity control system and the water level detection module for detecting the water level.

[0074] In some embodiments, determining whether there is an abnormality in the internal water circuit of the humidity control system may include determining whether there is an abnormality in the water circuit between the water inlet 240 of the humidity control system 200 and the water tank 2101, between the water tank 2101 and the water outlet 250 of the humidity control system 200, between the water tank 2101 and the humidification module 220, and between the humidification module 220 and the water outlet 250 of the humidity control system 200.

[0075] For example, it may be detected whether the first valve 2102 disposed between the water tank 2101 and the water inlet 240 of the humidity adjustment system 200 has an abnormality.

[0076] When the first valve 2102 is set to the closed state, if no water level change of the water tank 2101 is detected within the detection cycle, the closed state of the first valve 2102 is normal, and / or the water level detection module 260 is normal. For example, when the first valve 2102 is set to the closed state, a detection signal indicating that the water level has not changed is received within the first detection cycle, or a detection signal indicating that the water level has changed is not received within the second detection cycle, then the closed state of the first valve 2102 is normal.

[0077] The second detection period can be longer than the first detection period, thereby improving the accuracy of the detection result and helping to reliably determine whether there is an abnormality in the first valve 2102. The present application is not limited thereto, and the second detection period can also be shorter than the first detection period or the same as the first detection period.

[0078] When the first valve 2102 is set to a closed state, if a water level change is detected during the detection cycle, at least one of the closed state of the first valve 2102 and the water level detection module 260 is abnormal. For example, if a rise in the water level in the water tank 2101 is detected during the detection cycle, at least one of the closed state of the first valve 2102 and the water level detection module 260 is abnormal.

[0079] When the first valve 2102 is set to an open state, if the water level of the water tank 2101 changes during the detection period, the first valve 2102 is normally open, and / or the water level detection module 260 is normal. For example, when the first valve 2102 is set to an open state, if the water level changes to a preset position during the detection period, the first valve 2102 is normally open.

[0080] When the first valve 2102 is set to the open state, if no water level change is detected within the detection cycle, at least one of the open state of the first valve 2102 and the water level detection module 260 is abnormal. For example, when the first valve 2102 is set to the open state, if a detection signal indicating that the water level has not changed is received within the first detection cycle, or a detection signal indicating that the water level has not changed is not received within the second detection cycle, or if the water level has not changed to a preset position within the detection cycle, at least one of the open state of the first valve 2102 and the water level detection module 260 is abnormal.

[0081] The preset position may be a position related to the length of the detection cycle, the water inflow speed of the water tank 2101, the volume of the water tank 2101, etc. In addition, in the above abnormality detection process, if the water tank 2101 supplies water to the humidification unit 2201 or the water tank 2101 discharges water to the drain port 250, then the preset position is also related to the water supply speed or the drainage speed.

[0082] During the above abnormality detection process, the water outlet of the water tank 2101 may be in a closed state. For example, the second valve 211 on the water outlet side of the water tank 2101 is closed to prevent the water tank 2101 from supplying water to the humidifying unit 2201 of the humidifying module 220, and / or to prevent the water tank 2101 from draining water to the drain port 250 of the humidity adjustment system 200. Figure 3 As shown, when the second valve 211 is a three-way valve, the first port a and the second port b of the second valve 211 can be cut off, the first port a and the third port c can be cut off, and the second port b and the third port c can be connected. Since the water path between the water tank 2101 and the humidifying unit 2201 and the water path between the water tank 2101 and the drain port 250 are cut off, the change of the water level of the water tank 2101 can be detected in a shorter time, thereby improving the detection efficiency.

[0083] The present application is not limited thereto. As mentioned above, in the above-mentioned abnormality detection process, the water path between the water outlet of the water tank 2101 and the humidification unit 2201 of the humidification module 220 can also be set to be in a connected state. For example, the second valve 211 on the water outlet side of the water tank 2101 is set to supply water from the water tank 2101 to the humidification module 220. Figure 3 As shown, when the second valve 211 is a three-way valve, the first port a and the second port b of the second valve 211 can be connected, the second port b and the third port c can be cut off, and the first port a and the third port c can be cut off. Since the water path between the water tank 2101 and the humidifying unit 2201 is connected, when water is supplied to the water tank 2101, part of the water will flow into the humidifying unit 2201. Therefore, it takes longer time to detect the change of the water level than when the second valve 211 is in the closed state.

[0084] In some embodiments, the first valve 2102 may include one or more sub-valves. When the first valve 2102 includes multiple sub-valves, the multiple sub-valves may be connected in various ways, such as in parallel, in series, in parallel and in series, etc. When the first valve 2102 includes more than two sub-valves connected in series on the water inlet side of the water tank 2101, setting the first valve 2102 to a closed state includes setting at least one sub-valve to a closed state, and setting the first valve 2102 to an open state includes setting all sub-valves to an open state.

[0085] like Figure 3 As shown, the first valve 2102 may include a first sub-valve 2102 - 1 and a second sub-valve 2102 - 2 which are arranged in series at the water inlet side of the water tank 2101 .

[0086] When the first sub-valve 2102-1 is set to closed, the second sub-valve 2102-2 is set to open, and the second valve 211 is set to close the water outlet of the water tank 2101 and the water outlet of at least one of the humidification module 220, and no water level change is detected within the detection period, the closed state of the first sub-valve 2102-1 is normal.

[0087] When the first sub-valve 2102-1 is set to open, the second sub-valve 2102-2 is set to closed, and the second valve 211 is set to close the water outlet of the water tank 2101 and the water outlet of at least one of the humidification module 220, and no water level change is detected within the detection period, the closed state of the second sub-valve 2102-2 is normal.

[0088] When the first sub-valve 2102-1 is set to open, the second sub-valve 2102-2 is set to open, and the second valve 211 is set to close the water outlet of the water tank 2101 and the water outlet of at least one of the humidification module 220, if a water level change is detected within the detection cycle, the first sub-valve 2102-1 and the second sub-valve 2102-2 are in a normal open state. For example, if a water level rise is detected within the detection cycle or the water level rises to a preset position, the first sub-valve 2102-1 and the second sub-valve 2102-2 are in a normal open state.

[0089] In some embodiments, in the control method of the humidity adjustment system 200, it is possible to detect whether there is an abnormality in the second valve 211. Below, the control method is exemplarily described by taking the second valve 211 being arranged between the water outlet of the water tank 2101 and the humidifying unit 2201 of the humidifying module 220 to control the on-off of the water path between the water outlet of the water tank 2101 and the humidifying unit 2201 of the humidifying module 220 as an example.

[0090] In some embodiments, when water is stored in the water tank 2101 and the state of the second valve 211 is set to supply water from the water tank 2101 to the humidification module 220, a water level change is detected within the detection cycle, and the water supply state of the second valve 211 is normal. For example, if the water level is detected to drop to a preset position within the detection cycle, the water supply state of the second valve 211 is normal; if no water level change is detected within the detection cycle, the water supply state of the second valve 211 is abnormal. For example, if a detection signal indicating that the water level has not changed is received within the first detection cycle, or if a detection signal indicating that the water level has changed is not received within the second detection cycle, or if it is detected that the water level has not changed to the preset position within the detection cycle, the water supply state of the second valve 211 is abnormal.

[0091] In the process of detecting the second valve 211, the first valve 2102 may be in a closed state. Thus, the change in the water level of the water tank 2101 can be detected in a shorter time, thereby improving the detection efficiency. The present application is not limited thereto, and in the process of detecting the second valve 211, the first valve 2102 may also be in an open state. In this case, it can be determined whether the second valve 211 is abnormal based on the speed of the water level change, etc. For example, when the speed of water inflow from the first valve 2102 to the water tank 2101 is greater than the speed of water supply from the water tank 2101 to the humidification unit 2201, a water level rise is detected within the detection cycle, and the speed of the rise is smaller than the speed of the water level rise when the first valve 2102 is opened and the drain port of the water tank 2101 is closed, then the water supply state of the second valve 211 can also be considered normal.

[0092] In some embodiments, when the humidity adjustment system 200 includes the air supply module 230, Figure 1 As shown, the control method may also include:

[0093] Step 103 , when confirming that the water supply state of the second valve 230 is normal, the air supply module 230 introduces air into the humidification module 220 within a preset time.

[0094] Thus, the humidifying unit 2201 (eg, a wet film, etc.) of the humidifying module 220 can be dried, thereby reducing the possibility of bacteria breeding in the humidifying module 220 .

[0095] In some embodiments, Figure 1 As shown, the control method may also include:

[0096] Step 104 , when at least one of the first valve 2102 , the second valve 211 and the water level detection module 260 is abnormal, corresponding abnormal information is prompted.

[0097] This makes it easier for the user to understand abnormal modules or components in the humidity control system 200, which is beneficial for subsequent maintenance.

[0098] In some embodiments, different abnormality information may be prompted for abnormalities occurring in different components or modules, so that the user can accurately understand the component or module in which the abnormality occurs.

[0099] In some embodiments, in the test operation mode of the humidity control system, the refrigerant valve 2203 of the humidification module 220 can be in a closed state. Thus, the refrigerant flow in the humidification module 220 can be avoided, the control in the test operation mode can be simplified, and even if the refrigerant pipeline of the humidity control system 200 is not connected or the refrigerant pipeline is abnormal, the internal water circuit or water level detection module of the humidity control system 200 can be detected. The present application is not limited to this, and in the test operation mode of the humidity control system, the refrigerant valve 2203 of the humidification module 220 can also be in an open state.

[0101] like Figure 5 As shown, the control method may include:

[0102] Step 501: close the solenoid valve 1 (first sub-valve) and the solenoid valve 2 (second sub-valve);

[0103] Step 502: Switch the three-way valve (second valve) to the drainage side, that is, the second port b and the third port c are connected, and the first port a and the third port c, and the first port a and the second port b are blocked;

[0104] Step 503: Keep the solenoid valve 1 (the first sub-valve) closed and open the solenoid valve 2 (the second sub-valve);

[0105] Step 504: after a period of time (e.g., 5 minutes), determine whether the states of the first float switch FS4, the second float switch FS1, and the third float switch FS2 are OFF, OFF, and ON, that is, the water level is not detected. If the judgment result is yes (the water level is not detected), execute step 505, otherwise execute step 506;

[0106] Step 505: Open the solenoid valve 1 (the first sub-valve) and close the solenoid valve 2 (the second sub-valve);

[0107] Step 506: Prompt abnormal information of the solenoid valve 1, for example, the closing state of the solenoid valve 1 is abnormal;

[0108] Step 507: after a period of time (e.g., 5 minutes), determine whether the states of the first float switch FS4, the second float switch FS1, and the third float switch FS2 are OFF, OFF, and ON, that is, the water level is not detected, or, after a period of time (e.g., 15 minutes), whether the detection signal of the water level change is not received. If the judgment result is yes (the water level is not detected or the detection signal of the water level change is not received), the detection of the solenoid valve 1 and the solenoid valve 2 is completed, otherwise, execute step 508;

[0109] Step 508: Prompt abnormal information of the solenoid valve 2, for example, the closing state of the solenoid valve 2 is abnormal.

[0110] Figure 6 is another schematic diagram of the control method of the embodiment of the present application. Figure 6 The specific implementation of the control method of the embodiment of the present application is exemplarily described.

[0111] like Figure 6 As shown, in the control method, the three-way valve (second valve) can be tested. Figure 6 The methods in can be executed individually or together with Figure 5 The method shown is performed together with Figure 5 When the method is executed together, it is not limited Figure 5 and Figure 6 The execution order of the method shown, for example, can be executed first Figure 5 Then execute the method in Figure 6 Alternatively, you can first execute Figure 6 Then execute the method in Figure 5 methods in , and so on.

[0112] like Figure 6 As shown, the control method may include:

[0113] Step 601, switch the three-way valve (second valve) to the drainage side, that is, the second port b and the third port c are connected, and the first port a and the third port c, the first port a and the second port b are cut off; it is worth noting that if the first Figure 5 In the method shown, step 601 may be omitted;

[0114] Step 602, opening the solenoid valve 1 (first sub-valve) and the solenoid valve 2 (second sub-valve) to supply water to the water tank 2101;

[0115] Step 603, closing the solenoid valve 1 (first sub-valve) and the solenoid valve 2 (second sub-valve);

[0116] Step 604, after a period of time (for example, 3 minutes), determine whether the states of the first float switch FS4, the second float switch FS1, and the third float switch FS2 are ON, ON, and OFF, that is, a high water level is detected. If the judgment result is yes (a high water level is detected), it means that the opening states of the solenoid valve 1 and the solenoid valve 2 are normal, and there is water in the water tank 2101, and step 605 is executed; otherwise, step 606 is executed;

[0117] Step 605, switch the three-way valve (second valve) to the water supply side, that is, the first port a and the second port b are connected, and the first port a and the third port c, the second port b and the third port c are blocked;

[0118] Step 606, prompting abnormal information of solenoid valve 1 and solenoid valve 2, for example, prompting that the opening state of solenoid valve 1 and solenoid valve 2 is abnormal, that is, water tank 2101 cannot enter water;

[0119] Step 607, after a period of time (for example, 2 minutes), determine whether the states of the first float switch FS4, the second float switch FS1, and the third float switch FS2 are OFF, OFF, and ON, that is, the water level is not detected. If the judgment result is yes (the water level is not detected), it means that the water supply state of the three-way valve (the second valve) is normal, and step 608 is executed. Otherwise, step 609 is executed.

[0120] Step 608, the air supply module 230 is made to introduce air into the humidification module 220, for example, the following command "fan ON / OFF command" = valid, "fan gear indication" = 3 (strong) is sent to the air supply module 230;

[0121] Step 609, prompting abnormal information of the three-way valve (second valve), for example, prompting that the water supply state of the three-way valve is abnormal;

[0122] Step 610, after a period of time (for example, 40 minutes), the air supply module 230 stops introducing air into the humidification module 220, for example, the following command "fan ON / OFF command" = invalid is sent to the air supply module 230;

[0123] Step 611, the three-way valve (second valve) detection is completed.

[0124] It is worth noting that the above Figure 1 , 5 6 are only schematic illustrations of the embodiments of the present application, but the present application is not limited thereto.
