Description

Technical Field

[0001] This invention relates to the field of dehumidification structures, and in particular to a multifunctional dehumidifier, dehumidification system, and control method. Background Technology

[0002] Dehumidification methods mainly include physical dehumidification using air conditioners and adsorption dehumidification using rotary structures. In the food industry (dehydration), physical dehumidification using air conditioners is the preferred choice. During the dehydration process of seafood products, it is necessary to maintain a relatively high temperature (at least not the cold air from an air conditioner) for continuous dehumidification.

[0003] Due to the limitations of air conditioners' working principle, they cannot provide dehumidification when heating the air, but they can provide dehumidification when cooling the air. For example, Chinese patent CN209371642U describes a cooling tower installed outside the room, where the dehumidifier's condenser is cooled by cooling water supplied by the tower; or a floor-standing indoor air conditioner unit installed in a room near the other end of a horizontal partition, with its air intake facing the duct and its exhaust facing upwards, and an outdoor unit installed outside the room, connected to the indoor unit via pipes and wires; a fan is mounted on the horizontal partition, with its air intake on the side away from the duct and its exhaust on the side closer to the duct, pushing airflow towards the duct, which then guides the airflow into the room below the horizontal partition. When dehydrating a target space, the indoor and outdoor units of an air conditioner are usually placed separately inside and outside the target space. The indoor unit heats and controls the temperature of the target space, and a dehumidification valve structure needs to be installed in the target space. That is, the air conditioner sends hot but humid air into the target space to replace the high humidity air in the target space. This method cannot efficiently achieve the purpose of dehydration. At the same time, the simple working method results in poor dehydration effect. To achieve more working methods, a more complex system is required. Summary of the Invention

[0052] Reference Figures 1 to 6 In one embodiment of the present invention, a multi-functional dehumidifier includes:

[0053] An air outlet chamber 100 is located at one end of the length direction of the multi-functional dehumidifier 001;

[0054] The main exhaust duct 200 is arranged along the length of the multi-functional dehumidifier 001 and connected to the air outlet chamber 100. The main exhaust duct 200 is provided with a first exhaust chamber 210 and a second exhaust chamber 220 that are connected to each other. A first guide valve 230 is provided between the first exhaust chamber 210 and the second exhaust chamber 220. A second guide valve 240 is provided between the second exhaust chamber 220 and the air outlet chamber 100. The first exhaust chamber 210 is provided with an air inlet window 211 for connecting to the target space.

[0055] A main dehumidification channel 300 runs parallel to the main exhaust channel 200 and connects to the air outlet chamber 100. The main dehumidification channel 300 is provided with a second heat exchanger section 310, a first air supply chamber 320, an aluminum foil heat exchanger assembly 330, a second air supply chamber 340, and a first heat exchanger section 350. The second heat exchanger section 310 is connected to the air outlet chamber 100. The first air supply chamber 320 is connected to the second heat exchanger section 310. The first air supply chamber 320 is connected to the second exhaust chamber 220 through the aluminum foil heat exchanger assembly 330. The second air supply chamber 340 is connected to the air outlet chamber 100 through the aluminum foil heat exchanger assembly 330. The second air supply chamber 340 is connected to the first heat exchanger section 350. A third open valve 360 ​​is provided between the second air supply chamber 340 and the first exhaust chamber 210. A fourth open valve 321 for connecting to the external environment is provided on the first air supply chamber 320.

[0056] The air inlet of the first fan 400 is connected to the first heat exchanger section 350, and the air outlet of the first fan 400 is used to connect to the target space.

[0057] The second fan 500 is installed inside the air outlet chamber 100, and its air outlet is connected to the outside of the air outlet chamber 100;

[0058] The air conditioning operating system 600 connects the first heat exchanger section 350 and the second heat exchanger section 310.

[0059] In the existing technology, due to the limitations of the working principle of air conditioners, they cannot provide dehumidification when heating the air, but they can provide dehumidification when cooling the air.

[0060] In this invention, multiple operating modes are formed mainly through the main exhaust duct 200 and the main dehumidification duct 300, and the interaction between the two. The air inlet 211 of the multi-functional dehumidifier 001 and the air outlet of the first fan 400 can be connected to the target space through air guide pipes to achieve air extraction and supply to the target space; no structural modifications to the target space are required, greatly reducing the difficulty of installation and eliminating the difficulty of transporting it to the corresponding location (such as high floors or small spaces). The operating modes of the multi-functional dehumidifier 001 include: cooling mode, heating mode, full exhaust mode, closed dehumidification mode, and open dehumidification mode.

[0061] The air outlet chamber 100 is located at one end of the length of the multi-functional dehumidifier 001. It not only serves to install the second fan 500, but also acts as a communication channel between the main exhaust duct 200 and the main dehumidification duct 300. Its name does not limit its function.

[0062] The main exhaust duct 200 spatially includes a first exhaust chamber 210 and a second exhaust chamber 220. A first open valve 230 is provided between the first exhaust chamber 210 and the second exhaust chamber 220. A second open valve 240 is provided between the second exhaust chamber 220 and the air outlet chamber 100. An air inlet window 211 for connecting to the target space is provided on the first exhaust chamber 210. The specific usage state of the main exhaust duct 200 can be adjusted by adjusting the openness of the first open valve 230 and the second open valve 240.

[0063] The main dehumidification channel 300 runs parallel to the main exhaust channel 200 and connects to the air outlet chamber 100. A first heat exchanger section 350 and a second heat exchanger section 310 are provided on the main dehumidification channel 300. The corresponding air conditioning operating system 600 is connected to the first heat exchanger section 350 and the second heat exchanger section 310. The air conditioning operating system 600 includes a four-way valve, a compressor, etc. Specifically, the air conditioning operating system 600 can switch the state of the first heat exchanger section 350 and the second heat exchanger section 310 between the evaporator and the condenser by adjustment.

[0064] The main dehumidification channel 300 spatially comprises a first air supply chamber 320, an aluminum foil heat exchanger assembly 330, and a second air supply chamber 340. The first air supply chamber 320 is connected to the second exhaust chamber 220 via the aluminum foil heat exchanger assembly 330, and the second air supply chamber 340 is connected to the exhaust chamber 100 via the aluminum foil heat exchanger assembly 330. The aluminum foil heat exchanger assembly 330 has two isolated passages that allow for sufficient heat exchange. The first passage of the aluminum foil heat exchanger assembly 330 connects the first air supply chamber 320 and the second exhaust chamber 220, and the second passage of the aluminum foil heat exchanger assembly 330 connects the second air supply chamber 340 and the exhaust chamber 100. The first air supply chamber 320 is connected to the second heat exchanger section 310. A third control valve 360 ​​is provided between the second air supply chamber 340 and the first exhaust chamber 210. The second air supply chamber 340 is connected to the first heat exchanger section 350. A fourth control valve 321 for connecting to the external environment is provided on the first air supply chamber 320.

[0065] The air inlet of the first fan 400 is connected to the first heat exchanger section 350, and the first fan 400 provides the power to deliver air into the target space.

[0066] The following describes the working conditions of each working mode:

[0067] Reference Figure 5In both cooling and heating modes, the main exhaust duct 200 is not connected to the external environment (the first open valve 230 and the second open valve 240 remain closed), the air inlet vent 211 remains open, the third open valve 360 ​​remains open, the first fan 400 remains operational, the air conditioning system 600 remains operational, and the first heat exchanger section 350 functions as either an evaporator or a condenser. Air in the target space is drawn through the negative pressure generated by the first fan 400, passes through the pathway formed by the above process (first exhaust chamber 210, second supply chamber 340, and first fan 400), and then passes through the temperature of the first heat exchanger section 350, achieving both cooling and heating effects. During the operation of the air conditioning system 600, the fourth open valve 321 remains open, and the second fan 500 draws air from the external environment through the second heat exchanger section 310 to complete its function.

[0068] Reference Figure 4 In full exhaust mode, the main dehumidification channel 300 is closed (this can be achieved by closing the third open valve 360 ​​and the aluminum foil heat exchanger assembly 330), the air inlet 211 remains open, the first open valve 230 remains open, the second open valve 240 remains open, the second fan 500 remains operational, and the air conditioning system 600 is not operational. The air in the target space is then exhausted to the outside environment through the negative pressure generated by the second fan 500, via the pathway formed by the above process (first exhaust chamber 210, second exhaust chamber 220, air outlet chamber 100, and second fan 500). It should be noted that during full exhaust mode, the target space needs to obtain fresh air from the outside environment. The above methods of obtaining fresh air from the external environment can be by opening a window in the target space, or by setting a fifth directional valve 341 on the second air supply chamber 340. Air from the external environment enters the target space after passing through the fifth directional valve 341, the second air supply chamber 340, the first heat exchanger section 350, and the first fan 400 (which can be turned on or off).

[0069] Reference Figure 6In the closed dehumidification mode, the air inlet 211 remains open, the first open valve 230 remains open, the second open valve 240 remains closed, the third open valve 360 ​​remains open, the aluminum foil heat exchanger assembly 330 remains operational, and the air conditioning system 600 remains operational (the first heat exchanger section 350 is used as an evaporator, and the second heat exchanger section 310 is used as a condenser). The air in the target space is drawn back to the target space by the negative pressure generated by the first fan 400 through the pathway formed by the above process (first exhaust chamber 210, second exhaust chamber 220, aluminum foil heat exchanger assembly 330, first supply air chamber 320, second heat exchanger section 310, air outlet chamber 100, aluminum foil heat exchanger assembly 330, second supply air chamber 340, and first fan 400). In this process, the purpose of dehumidification and temperature maintenance is achieved. Specifically, the humid and hot air in the target space absorbs heat through the aluminum foil heat exchanger assembly 330; it then cools and dehumidifies through the second heat exchanger section 310; it is then heated again through the aluminum foil heat exchanger assembly 330; and finally heated a second time through the first heat exchanger section 350. During this process, the humid and hot air in the target space within the aluminum foil heat exchanger assembly 330 heats the dry and cold air exiting the second heat exchanger section 310, reducing the energy consumption of both the first heat exchanger section 350 and the second heat exchanger section 310.

[0070] In open dehumidification mode, the third guide valve 360 ​​remains closed, the main exhaust duct 200 performs exhaust operation in full exhaust mode, and at the same time the multi-functional dehumidifier 001 operates in closed dehumidification mode.

[0071] During the operation of the various modes described above, the switching of the states of the first open valve 230, the second open valve 240, the third open valve 360, the fourth open valve 321, and the air conditioning system 600 can be done manually, or the multi-functional dehumidifier 001 can be equipped with a controller 700 to control the operation of all components. It is worth noting that by adjusting the states of each component, the multi-functional dehumidifier 001 can sometimes operate in parallel modes. In fact, the open dehumidification mode is the simultaneous activation of the closed dehumidification mode and the full exhaust mode. In other modes, the full exhaust mode can be operated simultaneously with the cooling mode or the heating mode, and the heating mode can be operated simultaneously with the closed dehumidification mode.

[0072] In summary, the air inlet 211 and the air outlet of the first fan 400 of the multi-functional dehumidifier can be connected to the target space through ductwork, greatly reducing the difficulty of installation and eliminating the difficulty of transporting it to the corresponding location. It mainly includes the main exhaust duct 200 and the main dehumidification duct 300, and the interaction between them to form multiple working modes, specifically realizing cooling mode, heating mode, full exhaust mode, closed dehumidification mode, and open dehumidification mode, greatly improving the flexibility of operation. The working mode of the multi-functional dehumidifier 001 can be switched by adjusting the operation of the first open valve 230, the second open valve 240, the third open valve 360, the fourth open valve 321, and the air conditioning system 600.

[0073] In one embodiment, the second air supply chamber 340 is provided with a fifth through valve 341 that connects to the external environment.

[0074] During the full exhaust mode, the target space needs to obtain fresh air from the external environment. This can be achieved by opening windows within the target space or by using the multi-functional dehumidifier 001. The methods for obtaining fresh air using the multi-functional dehumidifier 001 and delivering it to the target space are also varied (e.g., by setting an exhaust port at the second air supply chamber 340, the first air supply chamber 320, or even the air outlet chamber 100). In this embodiment, a fifth open valve 341 is installed on the second air supply chamber 340. When fresh air needs to be replenished to the target space, air from the external environment passes through the fifth open valve 341, the second air supply chamber 340, the first heat exchanger section 350, and the first fan 400 (which can be turned on or off) before entering the target space. The fifth open valve 341 is convenient to use and can be used in conjunction with either cooling or heating modes. In cooling mode, it also dehumidifies the fresh air.

[0075] In one embodiment, the first fan 400 includes a first airflow meter for acquiring its airflow, and the second fan 500 includes a second airflow meter for acquiring its airflow.

[0076] In this embodiment, the exhaust and supply air of the multi-functional dehumidifier 001 are precisely controlled by the operation of the first and second air volume sensors. The air volume information is particularly important when multiple modes are used together.

[0077] In one embodiment, the multi-functional dehumidifier further includes a controller 700, which controls the operation of the first open valve 230, the second open valve 240, the third open valve 360, the fourth open valve 321, the fifth open valve 341, the first fan 400, the second fan 500, and the air conditioning system 600.

[0078] In this embodiment, the controller 700 controls various components, enabling the multi-functional dehumidifier 001 to switch between cooling mode, heating mode, full exhaust mode, closed dehumidification mode, and open dehumidification mode. In particular, if multiple sensors are installed within the target space to match the multi-functional dehumidifier 001, the intelligent control of the multi-functional dehumidifier 001 can be further enhanced.

[0079] Reference Figure 7 The present invention also provides a dehumidification system, the dehumidification system including the above-mentioned multi-functional dehumidifier, the dehumidification system further including an internal temperature detection unit 810 and an internal humidity detection unit 820; the internal temperature detection unit 810 and the internal humidity detection unit 820 are used to be installed in the target space; the controller 700 receives data from the internal temperature detection unit 810 and the internal humidity detection unit 820.

[0080] In this embodiment, the internal temperature detection unit 810 and internal humidity detection unit 820 enable the multi-functional dehumidifier 001 to adapt to the humidity and temperature environment of the target space. Specifically, based on whether the temperature and humidity environment of the target space meets the requirements, the dehumidifier 001 can be activated according to the needs of cooling mode, heating mode, full exhaust mode, closed dehumidification mode, and open dehumidification mode. Alternatively, when the temperature and humidity environment of the target space meets the requirements, the multi-functional dehumidifier 001 can be paused. It should be noted that the number of internal temperature detection units 810 and internal humidity detection units 820 is not limited to one, and their placement is based on accurately obtaining temperature and humidity information of the target space. Correspondingly, there can be targeted methods for processing the data from the internal temperature detection unit 810 or internal humidity detection unit 820.

[0081] In one embodiment, the dehumidification system further includes an external temperature detection unit 910 and an external humidity detection unit 920: the external temperature detection unit 910 and the external humidity detection unit 920 are used to be set in the external environment; the controller 700 receives data from the external temperature detection unit 910 and the external humidity detection unit 920.

[0082] In the aforementioned embodiment, the multi-functional dehumidifier 001 primarily achieves complete air environment treatment (temperature and humidity) within the target space. In this embodiment, the dehumidification system also monitors the temperature and humidity information of the external environment. If the parameters of the external environment meet the required conditions, air from the external environment can be utilized during the exhaust process. Correspondingly, depending on the control method, direct air supply, cooling and dehumidifying air supply, and heating air supply can be selected to deliver air from the external environment into the target space.

[0083] The present invention also provides a control method applied to the above-mentioned dehumidification system, comprising:

[0084] S1 includes preset control procedures for heating mode, cooling mode, full exhaust mode, and closed-loop dehumidification mode.

[0087] In the full exhaust mode control process, the third conduction valve 360 ​​remains closed, the fourth conduction valve 321 remains closed, the aluminum foil heat exchanger assembly 330 remains closed, the first conduction valve 230 remains open, the second conduction valve 240 remains open, the fifth conduction valve 341 remains open, and the first fan 400 operates.

[0088] In the closed-loop dehumidification mode control process, the second conduction valve 240 remains closed, the third conduction valve 360 ​​remains closed, the fourth conduction valve 321 remains closed, the fifth conduction valve 341 remains closed, the first conduction valve 230 remains open, the aluminum foil heat exchanger assembly 330 remains open, the air conditioning system 600 operates, the first heat exchanger section 350 functions as a condenser, the second heat exchanger section 310 functions as an evaporator, and the first fan 400 operates.

[0089] S2. When the data from the internal humidity detection unit 820 is in the excessively high humidity range, the full exhaust mode control process is activated.

[0090] S3. When the data from the internal humidity detection unit 820 is within the excessively high humidity range, the full exhaust mode control process and the closed dehumidification mode control process will be activated.

[0091] S4. When the data from the internal humidity detection unit 820 is within the high humidity range, the closed dehumidification mode control process is activated.

[0092] S5. When the data from the internal humidity detection unit 820 is within the humidity range, but the data from the internal temperature detection unit 810 is outside the temperature range, the heating mode control process or the cooling mode control process is started.

[0093] Among them, the humidity ranges of extremely high humidity, excessively high humidity, relatively high humidity, and acceptable humidity are humidity ranges that decrease in a stepwise manner.

[0094] In step S1, there are fixed operating actions for the heating mode control process, cooling mode control process, full exhaust mode control process, and closed dehumidification mode control process. Specifically, in the corresponding control process, the open and closed states of each device are controlled according to the settings.

[0095] Several logical judgment conditions are proposed in steps S2 to S5. The specific judgment method is based on the test results of the internal humidity detection unit 820. At the same time, four humidity ranges are set down in stages: excessively high humidity range, high humidity range, relatively high humidity range, and humidity within standard range, which specifically express four different ranges of dehumidification urgency.

[0096] In step S2, when the data from the internal humidity detection unit 820 is in the excessively high humidity range, the full exhaust mode control process is activated. This means that during the initial drying stage or abnormal stage, all the air in the target space is replaced as quickly as possible. In full exhaust mode, the main dehumidification channel 300 is closed (this can be achieved by closing the third open valve 360 ​​and the aluminum foil heat exchanger assembly 330), the air inlet window 211 remains open, the first open valve 230 remains open, the second open valve 240 remains open, the second fan 500 remains operational, and the air conditioning system 600 is not operational. The air in the target space is then exhausted to the external environment through the suction negative pressure generated by the second fan 500 and the pathway formed by the above process (first exhaust chamber 210, second exhaust chamber 220, air outlet chamber 100, and second fan 500). It should be noted that during the full exhaust mode, the target space needs to obtain fresh air from the external environment. The air from the external environment enters the target space after passing through the fifth conduction valve 341, the second air supply chamber 340, the first heat exchanger section 350, and the first fan 400 (which can be turned on or off).

[0097] Before step S3, step S4 will be explained. In step S4, if the data from the internal humidity detection unit 820 shows that the humidity conditions in the target space are within a high humidity range or close to the humidity standard range, then the closed dehumidification mode control process will be activated. In the closed dehumidification mode, the air inlet 211 remains open, the first open valve 230 remains open, the second open valve 240 remains closed, the third open valve 360 ​​remains open, the aluminum foil heat exchanger assembly 330 remains operational, and the air conditioning system 600 remains operational (the first heat exchanger section 350 is used as an evaporator, and the second heat exchanger section 310 is used as a condenser). The air in the target space is drawn back to the target space by the negative pressure generated by the first fan 400 through the pathway formed by the above process (first exhaust chamber 210, second exhaust chamber 220, aluminum foil heat exchanger assembly 330, first supply air chamber 320, second heat exchanger section 310, air outlet chamber 100, aluminum foil heat exchanger assembly 330, second supply air chamber 340, and first fan 400). In this process, the purpose of dehumidification and temperature maintenance is achieved. Specifically, the humid and hot air in the target space absorbs heat through the aluminum foil heat exchanger assembly 330; it then cools and dehumidifies through the second heat exchanger section 310; it is then heated again through the aluminum foil heat exchanger assembly 330; and finally heated a second time through the first heat exchanger section 350. During this process, the humid and hot air in the target space within the aluminum foil heat exchanger assembly 330 heats the dry and cold air exiting the second heat exchanger section 310, reducing the energy consumption of both the first heat exchanger section 350 and the second heat exchanger section 310.

[0098] In step S3, when the data from the internal humidity detection unit 820 is within the excessively high humidity range, the full exhaust mode control process and the closed dehumidification mode control process are activated, which is the open dehumidification mode. This means that the air in the target space is exhausted to the outside environment, and the air in the target space is dehumidified. In the open dehumidification mode, the third guide valve 360 ​​remains closed, the main exhaust duct 200 performs the exhaust operation in the full exhaust mode, and at the same time, the multi-functional dehumidifier 001 operates in the closed dehumidification mode, which is equivalent to executing the operations in steps S2 and S4 simultaneously.

[0099] In step S5, the humidity has reached the target, so only temperature control is needed. In both cooling and heating modes, the main exhaust duct 200 is not connected to the external environment (the first open valve 230 and the second open valve 240 remain closed), the air inlet vent 211 remains open, the third open valve 360 ​​remains open, the first fan 400 remains operational, the air conditioning system 600 remains operational, and the first heat exchanger section 350 is used as an evaporator or condenser. Air in the target space is drawn through the negative pressure generated by the first fan 400, passing through the pathway formed by the above process (first exhaust chamber 210, second supply chamber 340, and first fan 400), and then heated by the temperature of the first heat exchanger section 350, achieving both cooling and heating effects. During the operation of the air conditioning system 600, the fourth open valve 321 remains open, and the second fan 500 draws air from the external environment through the second heat exchanger section 310 to complete its function.

[0100] In one embodiment, step S3 includes:

[0101] When the data from the internal humidity detection unit 820 is within the excessive humidity range, the full exhaust mode control process and the closed dehumidification mode control process are activated. Based on the position of the data from the internal humidity detection unit 820 within the excessive humidity range, the working intensity of the first fan 400 and the second fan 500 is adjusted.

[0102] In this embodiment, the open dehumidification mode in step S3 is specifically defined. The open dehumidification mode involves the simultaneous execution of both the full exhaust mode control process and the closed dehumidification mode control process. The ratio of these two modes is crucial to the overall control method. In this embodiment, based on the data from the internal humidity detection unit 820 within the excessively high humidity range, for example, if the data from the internal humidity detection unit 820 is closer to the upper limit of the excessively high humidity range (too high humidity), then the workload of the second fan 500 is increased relative to the first fan 400. In this case, the full exhaust mode control process is more effective, and the dehumidification system functions more efficiently. Conversely, if the data from the internal humidity detection unit 820 is closer to the lower limit of the excessively high humidity range (humidity is relatively low), then the workload of the second fan 500 is reduced relative to the first fan 400. In this case, the closed dehumidification mode control process is more effective, and the dehumidification system functions more efficiently.

[0103] In one embodiment, the first fan 400 includes a first airflow meter for acquiring its airflow, and the second fan 500 includes a second airflow meter for acquiring its airflow. Step S3 includes:

[0104] When the data from the internal humidity detection unit 820 is within the excessively high humidity range, the full exhaust mode control process and the closed dehumidification mode control process are activated, and the working intensity of the first fan 400 and the second fan 500 is adjusted according to the data from the internal humidity detection unit 820. The working intensity of the first fan 400 and the second fan 500 is determined according to the first air volume sensor and the second air volume sensor, respectively.

[0105] Compared to the previous embodiments, in this embodiment, the working intensity of the first fan 400 and the second fan 500 is reflected by the first air volume sensor and the second air volume sensor, which has a more accurate characteristic.

[0106] In one embodiment, step S2 includes:

[0107] S1.1, the full exhaust mode control process includes preset direct air supply control, cooling and dehumidifying air supply control, and heating air supply control.

[0108] In the direct air supply control process, the third conduction valve 360 ​​remains closed, the fourth conduction valve 321 remains closed, the aluminum foil heat exchanger assembly 330 remains closed, the first conduction valve 230 remains open, the second conduction valve 240 remains open, the fifth conduction valve 341 remains open, the first fan 400 operates, and the air conditioning system 600 does not operate.

[0109] In the heating and air supply control process, the third conduction valve 360 ​​remains closed, the fourth conduction valve 321 remains closed, the aluminum foil heat exchanger assembly 330 remains closed, the first conduction valve 230 remains open, the second conduction valve 240 remains open, the fifth conduction valve 341 remains open, the first fan 400 operates, the air conditioning system 600 operates, and the first heat exchanger section 350 functions as a condenser.

[0110] Cooling, dehumidifying, and air supply control process: the third conduction valve 360 ​​remains closed, the fourth conduction valve 321 remains closed, the aluminum foil heat exchanger assembly 330 remains closed, the first conduction valve 230 remains open, the second conduction valve 240 remains open, the fifth conduction valve 341 remains open, the first fan 400 operates, the air conditioning system 600 operates, and the first heat exchanger section 350 functions as an evaporator.

[0111] S1.2 When the data from the external temperature detection unit 910 is within the standard temperature range, the direct air supply control process is initiated.

[0112] S1.3 When the data from the external temperature detection unit 910 is lower than the standard temperature range, the heating and air supply control process is initiated.

[0113] S1.4 When the data from the external temperature detection unit 910 is higher than the standard temperature range, the cooling, dehumidification and air supply control process is initiated.

[0114] In this embodiment, the full exhaust mode control process is further divided into three parts: direct air supply control, cooling and dehumidifying air supply control, and heating air supply control. These three control processes arise from fluctuations in the ambient air temperature. The first heat exchanger 350 is used to offset the difference between the ambient air temperature and the standard temperature range, thus achieving a better full exhaust mode control process. Data from the external humidity detection unit 920 can also be used as a reference. When the ambient air humidity is high, the activation of the corresponding full exhaust mode control process needs to be cautious, especially when the ambient air humidity is high and the temperature is low. By distinguishing between the direct air supply control process, the cooling and dehumidifying air supply control process, and the heating air supply control process, the efficiency of the full exhaust mode control process is optimized.

[0115] In summary, the multi-functional dehumidifier, dehumidification system, and control method provided by this invention allow the air inlet 211 of the multi-functional dehumidifier and the air outlet of the first fan 400 to be connected to the target space via ductwork, significantly reducing the difficulty of installation and eliminating the need for transportation to the appropriate location. The system mainly includes a main exhaust duct 200 and a main dehumidification duct 300, and the interaction between them forms multiple operating modes, specifically implementing cooling mode, heating mode, full exhaust mode, closed dehumidification mode, and open dehumidification mode, greatly improving operational flexibility. The operating modes of the multi-functional dehumidifier 001 are switched by adjusting the operation of the first open valve 230, the second open valve 240, the third open valve 360, the fourth open valve 321, and the air conditioning system 600.

Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
