Description

Technical Field

[0001] This invention relates to the field of rotary dehumidification technology, specifically to a rotary dehumidifier unit and its control method. Background Technology

[0002] A rotary dehumidifier uses a continuously rotating desiccant wheel as its core. The desiccant wheel is generally divided into a dehumidification zone and a regeneration zone, with the air duct facing these two areas. Before entering the dehumidification zone, air is cooled and dehumidified by a surface cooler. Then, the desiccant wheel in the dehumidification zone adsorbs water vapor from the air. Driven by a drive unit, the desiccant wheel gradually rotates into the regeneration zone. In the regeneration zone, the high-temperature air desorbs water molecules from the desiccant wheel, allowing it to regain its adsorption capacity before gradually rotating back into the dehumidification zone. This cycle is repeated, continuously delivering dry air into a designated space and expelling humid air, thus achieving dehumidification.

[0003] When dealing with multiple spaces requiring different dehumidification intensities, it is usually necessary to set up multiple dehumidifiers of different specifications to dehumidify each space separately. This multi-device approach typically results in significant energy consumption. Furthermore, dehumidifiers generally have a limited dehumidification intensity range, and when faced with complex and variable environments, they cannot adapt to the diverse dehumidification needs of multiple spaces, leading to energy waste or inadequate dehumidification performance. Summary of the Invention

[0004] To address the shortcomings of the existing technology, this invention proposes a rotary dehumidifier unit and its control method to save energy consumption and improve the adaptability of the rotary dehumidifier unit to various humidity environments.

[0005] To achieve the above objectives, according to one aspect of the present invention, a rotary dehumidifier unit is provided, comprising a primary rotary dehumidifier having a primary rotary dehumidification zone and a primary rotary regeneration zone;

[0006] The primary rotary dehumidification zone is divided into primary rotary dehumidification zone one and primary rotary dehumidification zone two, and the area ratio of primary rotary dehumidification zone one and primary rotary dehumidification zone two relative to the primary rotary dehumidification zone is adjustable.

[0007] Furthermore, the primary rotary dehumidifier includes a primary rotary wheel and a primary partition wheel, the primary partition wheel being disposed on both sides of the primary rotary wheel, and the primary partition wheel being provided with a communication port for forming the primary rotary dehumidification zone and the primary rotary regeneration zone;

[0008] The primary desiccant wheel is also equipped with a partition rod and a drive component. The partition rod separates the communication openings used to form the primary desiccant wheel dehumidification zone, thereby dividing the primary desiccant wheel dehumidification zone into primary desiccant wheel dehumidification zone one and primary desiccant wheel dehumidification zone two. The drive component is driven and connected to the partition rod to drive the partition rod to move, thereby adjusting the area ratio of primary desiccant wheel dehumidification zone one and primary desiccant wheel dehumidification zone two relative to the primary desiccant wheel dehumidification zone.

[0009] Furthermore, the driving component includes:

[0010] A circular ring is concentrically arranged on the outer periphery of the first-level partition wheel. One end of the partition rod is rotatably connected to the center of the first-level partition wheel, and the other end is fixedly connected to the circular ring.

[0011] Several drive wheels are circumferentially spaced between the circular ring and the first-level partition wheel, and the drive wheels are connected to the circular ring by rolling friction.

[0012] The drive wheel is equipped with a power source, and the drive wheel is connected to any of the driving wheels via belt drive.

[0013] Furthermore, the primary partition wheel is provided with an arc-shaped limiting groove, and the partition rod is provided with a limiting pin that slides in cooperation with the limiting groove.

[0014] Furthermore, it also includes a two-stage rotary dehumidifier, which has a two-stage rotary dehumidification zone and a two-stage rotary regeneration zone, and the first-stage rotary dehumidification zone is connected to the second-stage rotary dehumidification zone.

[0015] Furthermore, the two-stage rotary dehumidifier includes a two-stage rotary wheel and a two-stage partitioned wheel. The two-stage partitioned wheel is disposed on both sides of the two-stage rotary wheel, and the two-stage partitioned wheel is provided with a communication port for forming the dehumidification zone and the regeneration zone of the two-stage rotary wheel.

[0016] The secondary rotating wheel includes a semi-circular secondary rotating wheel body one and a secondary rotating wheel body two. The secondary rotating wheel body one is fixedly arranged relative to the rotating shaft of the secondary rotating wheel, and the secondary rotating wheel body two is rotatable relative to the rotating shaft of the secondary rotating wheel.

[0017] When the secondary rotary dehumidifier is not working, the second secondary rotary body completely overlaps with the first secondary rotary body, and the secondary rotary body is semi-circular. When the secondary rotary dehumidifier is working, the second secondary rotary body does not overlap with the first secondary rotary body, and the secondary rotary body is circular.

[0018] Furthermore, the primary rotary dehumidifier also has a primary rotary cooling zone, and the secondary rotary dehumidifier also has a secondary rotary cooling zone.

[0019] Furthermore, the first-stage dehumidification zone and the first-stage cooling zone are provided with a first-stage pre-filter, a first-stage surface cooler, and a first-stage dehumidification fan in sequence along the air inlet direction. The first-stage regeneration zone is provided with a first-stage regeneration fan and a first-stage heater in sequence along the air inlet direction. The first-stage dehumidification zone one is provided with a first-stage post-filter one, and the first-stage dehumidification zone two is provided with a first-stage post-filter two. The air outlet of the first-stage cooling zone is connected to the air inlet of the first-stage surface cooler via a first-stage cooling fan.

[0020] Furthermore, the secondary rotor dehumidification zone and the secondary rotor cooling zone are sequentially provided with a secondary pre-filter, a secondary surface cooler, and a secondary dehumidification fan along the air inlet direction on the air inlet side. The secondary rotor regeneration zone is sequentially provided with a secondary regeneration fan and a secondary heater along the air inlet direction on the air inlet side. The secondary rotor dehumidification zone is provided with a secondary post-filter on the air outlet side. The air outlet of the secondary rotor cooling zone is connected to the air inlet of the secondary surface cooler via a secondary cooling fan. The air outlet of the primary post-filter is connected to the air inlet of the secondary pre-filter.

[0021] According to another aspect of the present invention, a control method for the above-described rotary dehumidifier unit is provided, comprising the following steps:

[0022] The space regulated by the first-level rotary dehumidification zone is the first space to be regulated, and the space jointly regulated by the first-level rotary dehumidification zone and the second-level rotary dehumidification zone is the second space to be regulated. The humidity of the first space to be regulated is greater than the humidity of the second space to be regulated.

[0023] The three areas of the first-stage rotary dehumidification zone are preset: the first area, the second area, and the third area, and the first area < the second area < the third area;

[0024] The first-stage rotor is preset to have two rotational speeds: a first rotational speed and a second rotational speed, where the first rotational speed is less than the second rotational speed.

[0025] The two preset rotational speeds of the secondary rotor are: a third speed and a fourth speed, with the third speed being less than the fourth speed;

[0026] The humidity of the first space to be regulated is preset to two levels: ha1 and ha2, where ha1 < ha2. The humidity of the second space to be regulated is preset to hb1.

[0027] The humidity of the two controlled spaces is collected and compared with the preset humidity value;

[0028] When the humidity of the space being conditioned is greater than ha2, the first-stage dehumidifier operates at the second speed, the first-stage dehumidification zone is adjusted to the third area, and the second-stage dehumidifier is started.

[0029] Determine whether the humidity of the second controlled space is greater than hb1. When the humidity of the second controlled space is greater than hb1, the second-stage rotor operates at the fourth speed. When the humidity of the second controlled space is less than hb1, the second-stage rotor operates at the third speed.

[0030] Furthermore, when the humidity of the first space being adjusted is less than ha1, the second-stage rotary dehumidifier does not start, and the first-stage rotary dehumidifier zone is adjusted to the first area;

[0031] Determine whether the humidity of the second controlled space is greater than hb1. When the humidity of the second controlled space is greater than hb1, the first-stage rotor runs at the second speed. When the humidity of the second controlled space is less than hb1, the first-stage rotor runs at the first speed.

[0032] Furthermore, when the humidity of the controlled space is between ha1 and ha2, the first-stage rotor operates at the second speed, and the dehumidification area of ​​the first-stage rotor is adjusted to the second area.

[0033] Determine whether the humidity of the second space being conditioned is greater than hb1. If the humidity of the second space being conditioned is greater than hb1, start the second-stage rotary dehumidifier and run the second-stage rotor at the third speed. If the humidity of the second space being conditioned is less than hb1, do not start the second-stage rotary dehumidifier.

[0034] Applying the technical solution of this invention, the single-stage rotary dehumidifier has two dehumidification zones, which can simultaneously adjust the humidity of two spaces, reducing equipment usage. At the same time, the area of ​​the two dehumidification zones is adjustable in real time within the adjustment zone, thereby enabling real-time adjustment of the dehumidification capacity of the two dehumidification zones and improving the adaptability of the dehumidifier unit to various humidity environments.

[0045] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.

[0046] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0047] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0048] To save energy consumption and improve the adaptability of rotary dehumidifiers to various humidity environments, this invention provides a rotary dehumidifier and its control method.

[0049] like Figure 1 As shown, the rotary dehumidifier unit of this embodiment includes a two-stage dehumidifier unit. The first-stage dehumidifier unit includes a first-stage pre-filter 1, a first-stage surface cooler 2, a first-stage heater 3, a first-stage post-filter 40, a second-stage post-filter 41, a first-stage dehumidifier fan 51, a first-stage regeneration fan 52, a first-stage cooling fan 53, and a first-stage rotary dehumidifier 6. The second-stage dehumidifier unit includes a second-stage pre-filter 13, a second-stage surface cooler 14, a second-stage heater 16, a second-stage post-filter 15, a second-stage dehumidifier fan 171, a second-stage regeneration fan 173, a second-stage cooling fan 172, and a second-stage rotary dehumidifier 12.

[0050] The primary rotary dehumidifier 6 has four zones: primary rotary dehumidification zone 1 60, primary rotary dehumidification zone 2 61, primary rotary regeneration zone 62, and primary rotary cooling zone 63. The secondary rotary dehumidifier 12 has three zones: secondary rotary dehumidification zone 121, secondary rotary regeneration zone 122, and secondary rotary cooling zone 123. Each zone has an independent air duct.

[0051] The three independent air ducts formed by the exhaust of the primary dehumidifier fan 51 connect to the primary rotary dehumidifier zone 1 (60), the primary rotary dehumidifier zone 2 (61), and the primary rotary cooling zone 63, respectively. The air inlet duct of the primary dehumidifier fan 51 contains a primary pre-filter 1 and a primary surface cooler 2. The primary pre-filter 1 performs preliminary dehumidification on the air entering the primary rotary dehumidifier 6, while the primary surface cooler 2 cools the air entering the primary rotary dehumidifier 6, lowering the air temperature and making it easier for water vapor in the air to be absorbed. The exhaust ducts of the primary rotary dehumidifier zone 1 (60) and the primary rotary dehumidifier zone 2 (61) are respectively equipped with a primary post-filter 40 and a primary post-filter 41, further filtering the air in the ducts. The exhaust port of the primary post-filter 41 is connected to the exhaust port of the secondary pre-filter 13, allowing the dehumidified air to enter the secondary rotary dehumidifier 12. The air inlet of the primary regeneration fan 52 is connected to the outside, and the air outlet is connected to the primary rotor regeneration zone 62 via the primary heater 3. The primary heater 3 heats the air, which allows the rotor to regain its moisture absorption capacity. The primary rotor cooling zone 63 allows the rotor to cool down rapidly when passing through this zone, improving the rotor's moisture absorption capacity. The air passing through the primary rotor cooling zone 63 is then returned to the primary surface cooler 2 by the primary cooling fan 53 for further cooling, thus allowing for recycling.

[0052] The two air ducts formed by the outlet of the secondary dehumidifier 171 connect the secondary rotary dehumidification zone 121 and the secondary rotary cooling zone 123, respectively. The air inlet duct of the secondary dehumidifier 171 contains a secondary pre-filter 13 and a secondary surface cooler 14. The secondary pre-filter 13 performs preliminary dehumidification on the air entering the secondary rotary dehumidifier 12, while the secondary surface cooler 14 cools the air entering the secondary rotary dehumidifier 12, lowering the air temperature and making it easier for water vapor in the air to be absorbed. A secondary post-filter 15 is installed in the outlet duct of the secondary rotary dehumidification zone 121 to further filter the air in the duct. The inlet of the secondary regeneration fan 173 connects to the outside, and the outlet connects to the secondary rotary regeneration zone 122 via a secondary heater 16. The secondary heater 16 heats the air, allowing the rotor to regain its moisture absorption capacity. The secondary rotor cooling zone 123 allows the rotor to cool down quickly when passing through this zone, improving the rotor's moisture absorption capacity. The air passing through the secondary rotor cooling zone 123 returns to the secondary surface cooler 14 for cooling via the secondary cooling fan 172, and can be recycled.

[0053] like Figure 2 As shown, the primary rotary dehumidifier 6 includes an air inlet duct 10, a transition air duct 9, a primary zone wheel 8, a primary rotor 7, and an air outlet duct 11.

[0054] like Figure 3 As shown, the primary partition wheel 8 includes a partition rod 81, a drive wheel 82, a power wheel 83, and a limiting groove 84. The primary partition wheel 8 is divided into three fixed communication ports by three fixed arms 86. The largest communication port is further divided into two variable communication ports by the partition rod 81, corresponding to the four areas of the primary rotary dehumidifier 6: primary rotary dehumidification zone one 60, primary rotary dehumidification zone two 61, primary rotary regeneration zone 62, and primary rotary cooling zone 63. One end of the partition rod 81 rotates around the center of the primary partition wheel 8 within the fan-shaped area limited by the limiting groove 84, thereby changing the area of ​​primary rotary dehumidification zone one 60 and primary rotary dehumidification zone two 61. The driving force of the partition rod 81 comes from the power wheel 83. Specifically, the power wheel 83 drives the drive wheel 82 via belt transmission, and the drive wheel 82 drives the external ring 85 to rotate through friction. The ring 85 is fixedly connected to the other end of the partition rod 81, thereby driving the partition rod 81 to rotate. Multiple drive wheels 82 are arranged circumferentially between the ring 85 and the first-level partition wheel 8, which both drive the ring 85 to rotate and provide support for the rotation of the ring 85.

[0055] Combination Figure 2The transition duct 9 and the first-stage rotary dehumidifier 8 of the first-stage rotary dehumidifier 6 have the same diameter as the first-stage rotary dehumidifier 7. The air inlet pipes 10 correspond to the first-stage rotary dehumidification zone 1 60, the first-stage rotary dehumidification zone 2 61, the first-stage rotary regeneration zone 62, and the first-stage rotary cooling zone 63, respectively. Each air duct is independent. The transition duct 9 has independent air ducts corresponding to the four zones of the first-stage rotary dehumidifier 8. The connection between the transition duct 9 and the first-stage rotary dehumidifier 8 also includes a rod that rotates synchronously with the partition rod 81, ensuring that the size of the air duct with the first-stage rotary dehumidifier 8 can change with the rotation of the partition rod 81. At the same time, the air ducts in the transition duct 9 are divided by flexible material to ensure that the size of the air duct on the side connected to the air inlet pipe 10 and the air outlet pipe 11 does not change.

[0056] The two-stage rotary dehumidifier 12 has a similar structure to the one-stage rotary dehumidifier 6, including a two-stage rotor and a two-stage zone rotor. For example... Figure 4 As shown, the secondary-level wheel is divided into three connecting ports, which correspond to the three areas of the secondary-level wheel: the secondary-level wheel dehumidification zone 121, the secondary-level wheel regeneration zone 122, and the secondary-level wheel cooling zone 123.

[0057] like Figure 5 and Figure 6 As shown, the secondary rotor consists of two semi-circular rotor bodies, namely secondary rotor body one 18 and secondary rotor body two 19. Secondary rotor body one 18 is fixed relative to the shaft of the secondary rotor, while secondary rotor body two 19 can rotate relative to the shaft of the secondary rotor under the drive of the drive mechanism. When the secondary rotor dehumidifier 12 is not working, secondary rotor body one 18 and secondary rotor body two 19 completely overlap, and the secondary rotor as a whole forms a semi-circle. Figure 5 As shown, and located on one side of the secondary rotor regeneration zone 122 and the secondary rotor cooling zone 123, air entering from the primary post-filter 41 can pass directly through the secondary rotor regeneration zone 121. When the secondary rotor dehumidifier 12 is working, the secondary rotor body 18 and the secondary rotor body 19 do not overlap completely, and the secondary rotor is circular in shape. Figure 6 As shown, it operates in the form of a normal rotating wheel.

[0058] It should be noted that both the first-stage rotor 7 and the second-stage rotor have corresponding drive motors to drive their rotation, and the rotation of the second-stage rotor body 19 relative to the second-stage rotor shaft is changed by a separate drive mechanism.

[0059] In this embodiment, the areas of the first-stage dehumidification zone 60 and the second-stage dehumidification zone 61 include three preset proportions: the fan angles of the first-stage dehumidification zone 60 and the second-stage dehumidification zone 61 are 115° and 110°, 145° and 80°, and 175° and 50°, respectively; when the fan angle of the first-stage dehumidification zone 60 is 115°, it corresponds to the first area; when it is 145°, it corresponds to the second area; and when it is 175°, it corresponds to the third area. The first-stage dehumidification zone 7 has two preset rotational speeds: the first rotational speed and the second rotational speed, and the first rotational speed < the second rotational speed; the second-stage dehumidification zone has two preset rotational speeds: the third rotational speed and the fourth rotational speed, and the third rotational speed < the fourth rotational speed. The space regulated by the first-stage rotary dehumidification zone 60 is the first regulated space. The space jointly regulated by the first-stage rotary dehumidification zone 61 and the second-stage rotary dehumidification zone 121 is the second regulated space. The humidity of the regulated space 1 is greater than that of the regulated space 2. The humidity values ​​of the regulated space 1 are ha1 and ha2, and the humidity value of the regulated space 2 is hb1, where ha1 < ha2.

[0060] like Figure 7 As shown, the control method of the rotary dehumidifier unit in this embodiment is as follows:

[0061] The humidity of the two controlled spaces is collected and compared with the preset humidity value.

[0062] When the humidity of the first conditioned space is greater than ha2, the humidity of the first conditioned space is very high. The first-stage dehumidifier 7 operates at the second speed, and the first-stage dehumidification zone 60 is adjusted to the maximum third area to ensure the dehumidification capacity of the first conditioned space. The second-stage dehumidifier 12 is then started to ensure the dehumidification capacity of the second conditioned space. Then, it is determined whether the humidity of the second conditioned space is greater than hb1. When the humidity of the second conditioned space is greater than hb1, the humidity of the second conditioned space is relatively high, and the second-stage dehumidifier operates at the fourth speed. When the humidity of the second conditioned space is less than hb1, the humidity of the second conditioned space is relatively low, and the second-stage dehumidifier operates at the third speed to save energy.

[0063] When the humidity of the first space being conditioned is less than hb1, the humidity of the first space being conditioned is relatively low. The dehumidification needs of both spaces can be met by the first-stage rotary dehumidifier 6. Therefore, the second-stage rotary dehumidifier 12 is not started, and the first-stage rotary dehumidification zone 60 is adjusted to the minimum first area to ensure the dehumidification capacity of the first space being conditioned. Then, it is determined whether the humidity of the second space being conditioned is greater than hb1. When the humidity of the second space being conditioned is greater than hb1, the humidity of the second space being conditioned is relatively high, and the first-stage rotary dehumidifier 7 operates at the second speed. When the humidity of the second space being conditioned is less than hb1, the humidity of the second space being conditioned is relatively low, and the first-stage rotary dehumidifier 7 operates at the first speed to save energy.

[0064] When the humidity of the controlled space 1 is between ha1 and ha2, the humidity of the controlled space 1 is relatively high. At this time, the first-stage dehumidifier 7 needs to operate at the second speed, and the first-stage dehumidifier 6 needs to meet the dehumidification requirements of both spaces with a higher dehumidification capacity. The first-stage dehumidification zone 60 is adjusted to the middle second area to ensure the dehumidification requirements of the controlled space 1. Then, it is determined whether the humidity of the controlled space 2 is greater than hb1. When the humidity of the controlled space 2 is greater than hb1, the humidity of the controlled space 2 is relatively high. The second-stage dehumidifier 12 is started to assist in the dehumidification of the controlled space 2, and the second-stage dehumidifier operates at the third speed to save energy consumption. When the humidity of the controlled space 2 is less than hb1, the humidity of the controlled space 2 is relatively low, and the second-stage dehumidifier 12 is not started to save energy.

[0065] From the above description, it can be seen that the rotary dehumidifier unit of this application has at least the following advantages:

[0066] 1. Because the single-stage rotary dehumidifier adopts a rotary structure that includes two dehumidification zones, and the area of ​​the two processing zones is adjustable in real time within the adjustment zone, the equipment usage can be reduced, and the dehumidification capacity of the two processing zones can be adjusted in real time.

[0067] 2. Because a two-stage rotary dehumidifier with a new type of rotor has been designed, it can be used in conjunction with a single-stage rotary dehumidifier, further improving the adaptability of the rotary dehumidifier unit to various humidity environments.

[0068] 3. Since the speed of both the first and second stage rotors is adjustable, and through corresponding control methods, the speed can be adjusted to a suitable level under different dehumidification requirements, further improving the dehumidifier's adaptability to various humidity environments and saving energy consumption.
