[0002] This application claims priority to Chinese Patent Application No. 202410967230.9, filed on July 18, 2024, entitled “Dehumidification Device”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of gas dehumidification technology, and in particular to a dehumidification device. Background Technology

[0004] A dehumidifier, also known as a moisture remover or dehumidifier, is mainly composed of a compressor, heat exchanger, throttling device, drip tray, fan, controller, and outer casing. Its working principle is as follows: the fan draws humid air into the machine, and through heat exchange, the moisture in the air is condensed into water droplets that flow into the drip tray. The treated dry air is then discharged outside the machine. This cycle continues to reduce indoor humidity.

[0005] Dehumidifiers have a wide range of applications and a large market demand. They are widely used in laboratories, computer rooms, metrology rooms, libraries, archives, offices, material storage rooms, food and agricultural product warehouses, and other places to protect electronic products, optical instruments, precision equipment, and valuables from dampness and mold. With the development of science and technology, people have increasingly higher requirements for the environment of these special places, especially for humidity.

[0006] Traditional dehumidifiers require an appropriate airflow in the evaporator to lower the air temperature below the dew point for dehumidification. In current technology, the evaporator and condenser are usually designed with a single air duct and the same airflow. This airflow is too small for the condenser, resulting in increased condensing pressure, increased compressor pressure differential, increased compression ratio, and increased compressor power consumption, thus leading to lower energy efficiency.

[0032] In an optional implementation,

[0033] The dehumidification device also includes a secondary condenser;

[0034] The auxiliary condenser is disposed between the evaporator and the main condenser, and the distance between the auxiliary condenser and the evaporator is smaller than the distance between the auxiliary condenser and the main condenser.

The dehumidification device provided in this disclosure has a water-collecting component located below the evaporator. This component collects condensate and has a bottom airflow channel. Part of the gas to be dehumidified enters the evaporator, while the other part flows along the bottom airflow channel. Because the water-collecting component is located below the evaporator, the gas entering the bottom airflow channel bypasses the evaporator and is blown towards the main condenser, increasing the airflow into the main condenser. This dissipates heat from the main condenser, reduces compressor power consumption, and alleviates the technical problems of traditional dehumidifiers in the prior art, such as insufficient condenser ventilation, increased condensing pressure, increased compressor pressure difference, increased compression ratio, resulting in increased compressor power consumption and thus low energy efficiency.

Detailed Implementation

[0069] The technical solutions of this disclosure will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure. The components of the embodiments of this disclosure described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0070] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0071] In the description of this disclosure, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this disclosure. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0072] In the description of this disclosure, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0073] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0074] As shown in Figures 1 and 2, the dehumidification device provided in this embodiment includes an evaporator 100, a main condenser 200, a compressor 300, and a water collection component 400. The evaporator 100, the main condenser 200, and the compressor 300 are arranged sequentially along the gas flow direction, and the compressor 300 is connected to the evaporator 100 and the main condenser 200 by pipeline. The water collection component 400 is located below the evaporator 100 and is used to collect condensate.

[0075] It should be noted that, in order to reserve installation space for the water receiving component 400, the bottom surface of the evaporator 100 is higher than the bottom surface of the main condenser 200, so that there is a certain gap between the bottom surface of the evaporator 100 and the bottom plate of the outer shell. This gap is the installation space for the water receiving component 400, which facilitates the collection of condensate by the water receiving component 400.

[0076] The water receiving component 400 is provided with a bottom gas flow channel along the gas flow direction. The bottom gas flow channel is used to allow part of the gas to be dehumidified to bypass the evaporator 100 and be blown towards the main condenser 200. Specifically, the gas to be dehumidified is blown towards the evaporator 100. Since the water receiving component 400 is provided below the evaporator 100, and a bottom gas flow channel is opened on the water receiving component 400, part of the gas to be dehumidified enters the evaporator 100, and the other part of the gas to be dehumidified enters the bottom gas flow channel and flows along the bottom gas flow channel. This allows part of the gas to bypass the evaporator 100 and be blown directly towards the main condenser 200, increasing the air intake of the main condenser 200.

[0077] In addition, the overall dehumidification unit is also equipped with a throttling device. The function of the throttling device is to transform the high-pressure refrigerant liquid into a low-temperature, low-pressure refrigerant liquid after passing through the throttling device. Since the throttling device is a mature existing technology, its specific structure will not be described in detail here.

[0078] Existing dehumidifiers typically have bypass channels on the top or side of the evaporator to increase condenser airflow, which increases the overall size of the dehumidifier and occupies a large amount of space. However, in the embodiment of this application, a bottom gas flow channel is opened on the water receiving component 400 of the dehumidifier itself, which greatly reduces the size of the whole machine and saves space.

[0079] Regarding the structure and shape of the water receiving component 400, specifically:

[0080] The water receiving component 400 includes a water receiving tray housing 410; the water receiving tray housing 410 is provided with a bottom gas flow hole 411 through the gas flow direction, and a bottom gas flow channel is formed in the bottom gas flow hole 411. Some of the gas to be dehumidified enters the bottom gas flow hole 411, flows along the bottom gas flow hole 411, and is blown directly to the main condenser 200 after flowing out.

[0081] It should be noted that the end face of the water receiving tray housing 410 protrudes from the evaporator 100 and is designed with a slope to form a filter screen slot, which facilitates the fixing of the filter screen.

[0082] In an optional embodiment, the top of the water receiving pan housing 410 is provided with a water receiving trough 412 for collecting condensate. In order to ensure the collection of condensate, the evaporator 100 can be directly installed on the water receiving pan housing 410 so that the condensate can fall directly into the water receiving trough 412 on the top of the water receiving pan housing 410.

[0083] In an optional embodiment, one end of the top surface of the water receiving tray housing 410 is recessed downwards, while the top surface of the other end is flush, thus forming an inclined water receiving surface. A water receiving groove 412 is formed between the water receiving surface and the inner wall of the water receiving tray housing 410. Furthermore, the water receiving tray housing 410 is provided with a drain outlet 413, which is located at the bottom of the water receiving groove 412. The inclined water receiving groove 412 makes it easier to collect condensate at the bottom of the water receiving groove 412, facilitating the discharge of condensate from the drain outlet 413.

[0084] As shown in Figure 3, in an optional embodiment, the dehumidification device further includes a filter 700 and a fan 800; the filter 700 is disposed on the side of the evaporator 100 near the air inlet to filter the gas to be dehumidified. The fan 800 is disposed on the air outlet side of the main condenser 200, and the fan 800 plays the role of drawing air in, introducing the gas to be dehumidified into the dehumidification device.

[0085] In addition, as shown in Figure 6, the dehumidifier is also provided with an outer shell component 900. The outer shell component 900 is specifically a box-type shell structure, which covers the outside of the overall device. Ventilation holes are provided on both the air inlet and air outlet surfaces of the outer shell component 900 to ensure that the external gas to be dehumidified can enter the interior of the outer shell component 900.

[0086] The dehumidification device provided in this embodiment has a water-collecting component 400 installed below the evaporator 100. The water-collecting component 400 can collect condensate, and a bottom gas flow channel is opened on the water-collecting component 400. Part of the gas to be dehumidified enters the evaporator 100, and the other part of the gas to be dehumidified flows along the bottom gas flow channel. Since the water-collecting component 400 is located below the evaporator 100, the gas to be dehumidified entering the bottom gas flow channel bypasses the evaporator 100 and blows towards the main condenser 200, increasing the air intake of the main condenser 200, thereby dissipating heat from the main condenser 200, reducing the power consumption of the compressor 300, and alleviating the technical problems of low energy efficiency caused by insufficient condenser ventilation, increased condensing pressure, increased pressure difference, increased compression ratio, and increased power consumption of the compressor 300 in traditional dehumidifiers.

[0087] Based on the above embodiments, as shown in FIG4, in an optional embodiment, the dehumidification device water receiving component 400 provided in this embodiment further includes a bottom air volume control component 420; the bottom air volume control component 420 is disposed in the bottom air flow hole 411, and the bottom air volume control component 420 is configured to block the bottom air flow hole 411. The bottom air volume control component 420 is rotatably connected to the hole wall of the bottom air flow hole 411 so that the bottom air volume control component 420 can rotate to adjust the gas flow rate entering the bottom air flow hole 411.

[0088] Specifically, the bottom air volume control component 420 is configured as a louvered plate, which is rotatably connected to the bottom air flow hole 411. The opening degree of the bottom air flow hole 411 is controlled by the rotation of the louvered plate. Alternatively, the bottom air volume control component 420 can be configured as a drive motor and a rotating plate. The rotating shaft of the rotating plate passes through the water receiving tray housing 410 and is connected to the drive shaft of the drive motor. The driving force generated by the drive motor drives the rotating plate to rotate, thereby adjusting the opening degree of the bottom air flow hole 411.

[0089] On the other hand, with the total air intake remaining constant, the airflow rate of the evaporator 100 is changed by adjusting the airflow rate of the gas flow hole 411 at the bottom of the water receiving component 400, thereby achieving the airflow ratio between the evaporator 100 and the main condenser 200, and thus meeting the dehumidification requirements under different applications.

[0090] When the ambient temperature is low and the relative humidity is high, the difference between the dew point temperature and the ambient temperature is small, allowing the evaporator to handle a larger air volume to achieve maximum dehumidification. By using the bottom airflow control element 420 to keep the opening of the bottom gas flow hole 411 relatively small, the airflow into the evaporator 100 is large, resulting in less gas entering the bottom gas flow hole 411 and less airflow leaking to the main condenser 200.

[0091] When the ambient temperature is high and the relative humidity is low, the difference between the dew point temperature and the ambient temperature is large. Therefore, the evaporator airflow needs to be reduced to lower the air temperature below the dew point for dehumidification. Meanwhile, the condenser requires a large airflow to lower the condensation temperature. By using the bottom airflow control component 420 to increase the opening of the bottom gas flow hole 411, the airflow into the evaporator 100 is small, resulting in a larger volume of gas entering the bottom gas flow hole 411 and a larger volume of air leaking into the main condenser 200, thus improving the heat dissipation effect of the main condenser 200.

[0092] In an optional embodiment, as shown in FIG5, the dehumidification device further includes a top bypass component 500; the top bypass component 500 is disposed on the top of the main condenser 200, and the height of the top bypass component 500 is higher than that of the main condenser 200 and the evaporator 100. The top bypass component 500 is provided with a top gas flow hole 510 through it along the gas flow direction. A top gas flow channel is formed in the top gas flow hole 510. The top gas flow channel is used to allow part of the gas to be dehumidified to bypass the evaporator 100 and the main condenser 200 and mix with the air outlet of the main condenser 200.

[0093] Specifically, when the environment is at a high temperature above 40℃, the condensing and evaporating pressures of the dehumidifier increase, the compressor 300 operates under overload, and the outlet air temperature of the main condenser 200 also rises, further hindering the heat dissipation of the compressor 300. The compressor 300 shuts down for overheating protection, causing the dehumidifier to fail. At this time, the fan speed can be increased to increase airflow, and the top bypass component 500 can be opened. A portion of the relatively low-temperature gas to be dehumidified enters the top gas flow hole 510 and flows out, allowing this gas to bypass the evaporator 100 and the main condenser 200. Ultimately, this gas mixes with the high-temperature outlet air from the main condenser 200, and after its temperature decreases, it is blown towards the compressor 300, thereby improving the heat dissipation effect on the compressor 300 and expanding the operating temperature range of the dehumidifier.

[0094] In an optional embodiment, a top gas flow control element 520 is provided inside the top gas flow hole 510. The top gas flow control element 520 is configured to block the top gas flow hole 510. The top gas flow control element 520 is rotatably connected to the hole wall of the top gas flow hole 510 so that the top gas flow control element 520 can rotate to adjust the gas flow rate entering the top gas flow hole 510.

[0095] Specifically, the top air volume control component 520 is configured as a rotating plate, which can rotate along its own axis. By rotating the plate, the opening of the top air flow hole 510 is controlled.

[0096] The opening degree of the top air volume control component 520 can be adjusted according to the compressor housing temperature (or exhaust temperature) to prevent the compressor from overheating and shutting down.

[0097] In an optional embodiment, the dehumidification device further includes a secondary condenser 600; the secondary condenser 600 is disposed between the evaporator 100 and the main condenser 200, and the distance between the secondary condenser 600 and the evaporator 100 is less than the distance between the secondary condenser 600 and the main condenser 200.

[0098] Specifically, the auxiliary condenser 600 and the evaporator 100 are designed in close proximity, and the auxiliary condenser 600 and the evaporator 100 are combined into a module, which is installed on the water receiving component 400, thus saving space.

[0099] On the one hand, the auxiliary condenser 600 is used to cool the refrigerant liquid, which breaks the fin thermal bridge between the main condenser 200 and the auxiliary condenser 600, increases the subcooling of the refrigerant liquid at the end of the auxiliary condenser 600, helps to reduce the vaporization ratio of the refrigerant liquid in the throttling device, increases the evaporation heat absorption capacity of the refrigerant in the evaporator 100, and significantly improves the energy efficiency ratio of the dehumidifier.

[0100] On the other hand, the condensate collected in the water tank 412 is located within the negative pressure chamber of the entire air duct. When the airflow through the evaporator 100 is too fast, the condensate will be carried towards the air outlet. The auxiliary condenser 600 is designed to be close to the evaporator 100, so that the condensate encounters the auxiliary condenser 600, preventing the condensate from being carried away and splashing inside, and also preventing dirt and mold from growing inside the dehumidifier.

[0101] The dehumidification device provided in this embodiment can reduce the condensation temperature, dissipate heat from the main condenser 200, reduce the power of the compressor 300, reduce the ambient air temperature around the compressor 300, facilitate heat dissipation of the compressor 300, prevent the compressor 300 from overload protection due to high temperature, and achieve dehumidification control under different application environments.

[0102] The back of the water collection tank 412 is equipped with a heat insulation layer to prevent heat exchange. The back of the water collection tank 412, which contains low-temperature condensate, has a low temperature. When the incoming air is high-humidity and high-heat air, condensation will form on the back of the water collection tank 412.

[0103] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure, and are not intended to limit them. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this disclosure. Industrial applicability

[0104] The dehumidification device disclosed herein uses a water-collecting component located below the evaporator to collect condensate. A bottom gas flow channel is also provided on the water-collecting component. Part of the gas to be dehumidified enters the evaporator, while the other part flows along the bottom gas flow channel. Because the water-collecting component is located below the evaporator, the gas entering the bottom gas flow channel bypasses the evaporator and is blown towards the main condenser, increasing the airflow into the main condenser. This dissipates heat from the main condenser, reduces compressor power consumption, and alleviates the technical problems of low condenser ventilation, high condensing pressure, increased compressor pressure differential, and increased compression ratio in traditional dehumidifiers, which lead to increased compressor power consumption and consequently low energy efficiency.

[0105] Furthermore, it is understood that the dehumidification device provided in the embodiments of this application is reproducible and can be used in a variety of industrial applications. For example, the dehumidification device provided in the embodiments of this application can be applied to the field of gas dehumidification technology.
