Description

Technical Field

[0001] The invention relates to the technical field of dehumidifiers, and in particular to energy-saving industrial-grade indoor dehumidification equipment. Background Art

[0002] Industrial dehumidifiers are professional dehumidification equipment used in large areas or special environments. They are usually used in industrial production, warehousing, archives, underground engineering and other places. Compared with household dehumidifiers, industrial dehumidifiers have stronger dehumidification capacity and higher humidity processing efficiency. They are suitable for large or high humidity environments that require strict humidity control. In cold areas, frost is easy to form inside the dehumidifier, which affects the dehumidification efficiency. The dehumidifier needs to be equipped with an automatic defrost function.

[0003] An existing dehumidifier with a defrosting function is shown in the Chinese patent application with application number: 201820293471.X: A new dehumidifier with automatic defrosting, which includes a shell, an exhaust fan is fixedly connected to the left inner wall of the shell cavity, a compressor is fixedly connected to the bottom wall of the shell cavity, and fixed plates are fixedly connected to the front and rear sides of the right side of the bottom wall of the shell cavity. A condenser and an evaporator are respectively fixedly connected between the two fixed plates, and an exhaust pipe and an air return pipe are respectively connected to the surface of the compressor.

[0004] The prior art has the following defects: the above-mentioned dehumidifier realizes automatic melting of the frost layer on the surface of the evaporator by providing an exhaust pipe and a return pipe, but in industrial dehumidifiers, since the evaporator specifications of the industrial dehumidifier are relatively large, the energy consumption of defrosting using the above-mentioned method is high, which increases the operating cost and also imposes a burden on the environment. In addition, it is impossible to perform local treatment on areas where frost is more concentrated, and the defrosting efficiency is low, so there is room for improvement. Summary of the invention

[0005] In order to solve the above-mentioned technical problems, the present invention provides an energy-saving industrial-grade indoor dehumidification device to solve the technical problem that the existing dehumidifier cannot defrost a local area, resulting in high energy consumption and low defrosting efficiency.

[0006] The present invention is achieved through the following technical solutions:

[0007] An energy-saving industrial-grade indoor dehumidification device comprises a housing, an evaporator, a condenser, a fan, a defrost assembly and a controller; the evaporator, the condenser and the fan are sequentially arranged in the housing, an air inlet and an air outlet are arranged on the housing, the evaporator is arranged on a side close to the air inlet, the fan is arranged on a side close to the air outlet, a closed loop is formed between the evaporator and the condenser through a capillary tube and a compressor; a water receiving box is arranged at the bottom of the evaporator, the water receiving box discharges water through a liquid guide tube, the defrost assembly is arranged between the evaporator and the air inlet, the defrost assembly comprises a roller shaft, an adjustment plate and a driving member, a sponge is wound around the roller shaft, the roller shaft is rotatably mounted on the adjustment plate, the driving member is used to drive the roller shaft to rotate, the adjustment plate can slide in a vertical direction along the inner wall of the housing, and the controller is used to control the normal operation of each component.

[0008] Preferably, the roller shaft is also provided with a shovel blade, which is evenly arranged along the axis and circumference of the roller shaft, the roller shaft is wrapped in the sponge, and the shovel blade is arranged in a blunt arc shape.

[0009] Preferably, a bending portion is further provided at one end of the shovel blade away from the roller shaft, and an angle between the bending portion and the shovel blade is set to 120°-150°.

[0010] Preferably, the dehumidification equipment also includes a temperature sensor and a humidity sensor. The temperature sensor is used to detect the surface temperature of the evaporator, and the humidity sensor is used to detect the surface humidity of the evaporator. The temperature sensor and the humidity sensor feed back the measured data to the controller, and the controller instructs the driving part to rotate forward or reverse according to the feedback data.

[0011] Preferably, the evaporator is connected to a microchannel heat exchanger, a first pipeline is connected between the microchannel heat exchanger and the compressor, a second pipeline is connected between the microchannel heat exchanger and the roller, and a third pipeline is connected between the roller and the compressor.

[0012] Preferably, the adjustment plate is further provided with an adjustment component, the adjustment component comprises an adjustment rod, the adjustment rod is horizontally mounted on the adjustment plate, the adjustment rod is configured as a telescopic structure, and the roller is rotatably mounted on the telescopic end of the adjustment rod.

[0013] Preferably, the adjustment assembly further comprises an adjustment frame, the adjustment frame is hingedly mounted on the telescopic end of the adjustment rod, and both ends of the roller shaft are rotatably mounted on the adjustment frame respectively.

[0014] Preferably, the controller divides the measured temperature and humidity into level one, level two, level three and level four according to preset intervals. When the evaporator surface temperature is in the level one interval, the controller instructs the driving member to reverse, and instructs the first pipe to be connected, and the second pipe and the third pipe to be closed; when the evaporator surface temperature is in the level two interval, the controller instructs the driving member to rotate forward, and instructs the first pipe to be connected, and the second pipe and the third pipe to be closed; when the evaporator surface temperature is in the level three interval, the controller instructs the driving member to reverse, and instructs the first pipe to be closed, and the second pipe to be connected to the third pipe; when the evaporator surface temperature is in the level four interval, the controller instructs the driving member to rotate forward, and instructs the first pipe to be closed, and the second pipe to be connected to the third pipe.

[0016] Preferably, a second condensation plate and a third condensation plate are also arranged between the evaporator and the condenser. The compressor compresses the refrigerant into the condenser. The refrigerant flows through the condenser through the third condensation plate to the first condensation plate, and from the first condensation plate to the second condensation plate. The refrigerant flows from the second condensation plate through the liquid separator valve to the evaporator, and finally flows back to the compressor.

[0017] The beneficial effects of the present invention are:

[0018] 1. The frost layer in the frosted area can be removed by rotating the roller. By locally treating the frosted area, the equipment can concentrate energy and resources to clean up the thick frost layer, reducing the impact on the entire system and improving the defrosting efficiency. It reduces the energy required for heating, thereby reducing the overall energy consumption. The design of the defrosting component enables the equipment to respond quickly to the frosting situation and remove the frost layer in time to avoid the reduction of heat exchange efficiency caused by too thick frost layer. Reducing energy consumption not only reduces operating costs, but also reduces the burden on the environment, which meets the requirements of modern industry for sustainable development.

[0019] 2. The shovel blade can be set to effectively remove the thicker frost on the evaporator surface. When the roller is reversed, the physical action of the shovel blade can quickly remove the accumulated frost layer, making the defrosting process more efficient; when the roller is rotated forward, the bending part can directly act on the frost layer, quickly remove the frost layer, and improve the defrosting efficiency; the angle between the bending part and the shovel blade is set to 120°-150°. This angle design enables the bending part to apply force in a more effective way when it contacts the frost layer, increasing the contact area between the shovel blade and the frost layer, thereby improving the efficiency of removing the frost layer and reducing the risk of damage to the evaporator.

[0020] 3. The setting of the first condensation plate ensures that the refrigerant is in a suitable state before entering the evaporator, thereby improving the working efficiency of the evaporator; the setting of the second condensation plate further optimizes the flow and heat exchange process of the refrigerant, ensuring that the liquid refrigerant has reached the optimal temperature and pressure state before entering the evaporator, thereby improving the working efficiency of the evaporator; the main function of the third condensation plate is to preliminarily cool the refrigerant, so that its temperature has been partially reduced before entering the first condensation plate, reducing the heat loss of the refrigerant in the condenser, thereby improving the overall performance of the equipment.

[0039] See also Figure 1-Figure 6 , an energy-saving industrial-grade indoor dehumidification equipment, comprising a box body 1, an evaporator 2, a condenser 3, a fan 4, a defrost component 5 and a controller 6; the evaporator 2, the condenser 3 and the fan 4 are sequentially arranged in the box body 1, and an air inlet 7 and an air outlet 8 are arranged on the box body 1, the evaporator 2 is arranged on the side close to the air inlet 7, and the fan 4 is arranged on the side close to the air outlet 8, and a closed loop is formed between the evaporator 2 and the condenser 3 through a capillary tube and a compressor 9; a water receiving box is arranged at the bottom of the evaporator 2, and the water receiving box guides water out through a liquid guide tube, and the defrost component 5 is arranged between the evaporator 2 and the air inlet 7, and the defrost component 5 includes a roller 51, an adjusting plate 52 and a driving member, a sponge 10 is wound around the roller 51, and the roller 51 is rotatably installed on the adjusting plate 52, the driving member is used to drive the roller 51 to rotate, and the adjusting plate 52 can slide in a vertical direction along the inner wall of the box body 1, and the controller 6 is used to control the normal operation of each component.

[0040] The working principle of the dehumidification equipment in this application is as follows:

[0041] The device inhales indoor humid air through the air inlet 7, and the fan 4 is responsible for promoting the air flow; the inhaled humid air first passes through the evaporator 2. The refrigerant in the evaporator 2 evaporates under low pressure, absorbs heat in the air, and reduces the air temperature. When the air temperature drops below the dew point, the water vapor in the air begins to condense into water droplets to form condensed water; a water receiving tank is provided at the bottom of the evaporator 2, and the condensed water flows into the water receiving tank by gravity. The water receiving tank guides the collected water out through the liquid guide pipe, discharges it outside the machine or stores it; the refrigerant in the evaporator 2 becomes gaseous after absorbing heat, and then flows to the compressor 9. The compressor 9 compresses the gaseous refrigerant into a high-temperature and high-pressure gas and sends it to the condenser 3; in the condenser 3, the high-temperature and high-pressure refrigerant releases heat and becomes liquid after cooling. The condenser 3 usually exchanges heat with the outside air to help the refrigerant dissipate heat; the liquid refrigerant enters the evaporator 2 through the capillary tube. The function of the capillary is to reduce the pressure of the refrigerant so that it can evaporate quickly in the evaporator 2 and absorb more heat; the defrost assembly 5 is arranged between the evaporator 2 and the air inlet 7, and is mainly used to prevent frost on the surface of the evaporator 2. The defrost assembly 5 includes a roller 51, an adjustment plate 52 and a driving member. A sponge 10 is wound around the roller 51, and the rotation of the roller 51 can help remove the frost layer on the surface of the evaporator 2 and maintain the normal working efficiency of the evaporator 2. The adjustment plate 52 can slide in the vertical direction along the inner wall of the box 1 to adapt to different working conditions; the controller 6 is used to monitor and control the normal operation of each component, including the speed of the fan 4, the working state of the compressor 9 and the operation of the defrost assembly 5. The controller 6 automatically adjusts the working state of the equipment according to the indoor humidity and the set value to achieve the best dehumidification effect. Among them, the adjustment plate 52 can realize vertical movement by the motor driving the gear rack meshing, and can also realize vertical movement by winding the reel.

[0042] The rotation of the roller 51 can remove the frost layer in the frosted area, avoiding the high energy consumption of heating the entire evaporator 2 in the traditional defrosting method; by locally treating the frosted area, the equipment can concentrate energy and resources to clean the area with thicker frost layer, reducing the impact on the entire system and improving the defrosting efficiency; the traditional defrosting method usually needs to stop the dehumidification process and heat the entire evaporator 2, which not only wastes energy but also leads to reduced equipment operating efficiency. The equipment reduces the energy required for heating through local defrosting, thereby reducing the overall energy; the design of the defrost component 5 enables the equipment to respond quickly to the frosting situation and remove the frost layer in time to avoid the reduction of heat exchange efficiency due to excessively thick frost layer; through effective defrosting, the equipment can maintain continuous dehumidification capacity, avoid shutdown or efficiency reduction due to frosting, thereby improving overall work efficiency; the evaporator 2 of the industrial dehumidifier is usually large, and the traditional defrosting method has high energy consumption and low efficiency. The device uses local defrosting to treat areas with more concentrated frost, thereby avoiding energy waste on the entire evaporator 2; reducing energy consumption not only reduces operating costs, but also reduces the burden on the environment, which meets the requirements of modern industry for sustainable development.

[0043] See also Figure 4In order to quickly remove the accumulated frost layer and avoid sharp impact force on the surface of the evaporator 2, based on this, in one embodiment, a shovel blade 11 is also provided on the roller 51. The shovel blade 11 is evenly arranged along the axis and circumference of the roller 51. The roller 51 is wrapped in the sponge 10, and the shovel blade 11 is arranged in a blunt arc shape. The design of the shovel blade 11 enables it to effectively remove the thicker local frost on the surface of the evaporator 2. When the roller 51 is reversed, the accumulated frost layer can be quickly removed by the physical action of the shovel blade 11, ensuring that the heat exchange efficiency of the evaporator 2 is not affected; the existence of the shovel blade 11 makes the defrosting process more efficient, and can remove the frost layer in a shorter time, avoiding the performance degradation of the equipment due to the excessively thick frost layer; the shovel blade 11 adopts a blunt arc design to avoid direct impact between the shovel head and the surface of the evaporator 2. This design can effectively reduce the damage to the surface of the evaporator 2 and extend its service life; due to the shape design of the shovel blade 11, the shovel blade 11 will not generate sharp impact force when removing the frost layer, thereby reducing the risk of wear and damage to the evaporator 2 and ensuring the long-term stable operation of the equipment; by timely removing the frost layer on the surface of the evaporator 2, the shovel blade 11 can maintain the heat exchange efficiency of the evaporator 2 and ensure that the equipment is always in the best working condition during the dehumidification process; effective defrosting can reduce the increase in energy consumption of the equipment due to the thick frost layer, improve the overall energy efficiency, and reduce the operating cost; the setting of the shovel blade 11 is combined with the rotation of the roller 51, so that the equipment can flexibly adapt to different working conditions and environmental conditions. Whether it is an environment with high humidity or a situation with large temperature changes, the shovel blade 11 can effectively respond to ensure the stability and reliability of the equipment; the blunt head design of the shovel blade 11 also helps to reduce the noise generated when removing the frost layer, improve the quiet effect of the equipment, and is suitable for use in noise-sensitive environments.

[0044] See also Figure 4In order to improve the efficiency of removing the frost layer and optimize the contact angle, based on this, in one embodiment, a bending portion 12 is further provided at one end of the shovel blade 11 away from the roller shaft 51, and the angle between the bending portion 12 and the shovel blade 11 is set to 120°-150°. The design of the bending portion 12 makes it sharper than the shovel blade 11, and this sharp edge can effectively cut into and peel off the accumulated frost layer. When the roller shaft 51 rotates forward, the bending portion 12 can directly act on the frost layer, quickly remove the frost layer, and improve the defrosting efficiency; the angle between the bending portion 12 and the shovel blade 11 is set to 120°-150°. This angle design enables the bending portion 12 to apply force in a more effective way when contacting the frost layer, increasing the contact area between the shovel blade 11 and the frost layer, thereby improving the efficiency of removing the frost layer; the bending portion 12 presents a certain angle with the surface of the evaporator 2, and this design can effectively reduce the direct impact between the shovel blade 11 and the surface of the evaporator 2, and reduce the risk of damage to the evaporator 2. By optimizing the contact angle, the bend 12 can remove the frost layer while avoiding scratches or other damage to the surface of the evaporator 2; the design of the bend 12 makes the way of removing the frost layer more gentle, avoiding the damage that may be caused by the traditional shovel blade 11, ensuring the integrity and long-term stable operation of the evaporator 2; by effectively removing the frost layer, the bend 12 can help maintain the heat exchange efficiency of the evaporator 2 and ensure that the equipment is always in the best working condition during the dehumidification process. Timely removal of the frost layer can prevent the decrease in heat exchange efficiency due to excessively thick frost layer, thereby improving the overall performance of the equipment; the design of the bend 12 enables the shovel blade 11 to flexibly respond to changes in the frost layer under different environmental conditions. Whether in a high humidity environment or in conditions of large temperature changes, the bend 12 can effectively remove the frost layer to ensure the stability and reliability of the equipment.

[0045] In order to enable the device to maintain optimal performance under different working conditions and reduce unnecessary energy consumption, based on this, in one embodiment, the dehumidification device also includes a temperature sensor and a humidity sensor. The temperature sensor is used to detect the surface temperature of the evaporator 2, and the humidity sensor is used to detect the surface humidity of the evaporator 2. The temperature sensor and the humidity sensor feed back the measured data to the controller 6, and the controller 6 instructs the driving member to rotate forward or reverse according to the feedback data. The temperature sensor is used to detect the temperature of the surface of the evaporator 2, and the humidity sensor is used to detect the humidity of the surface of the evaporator 2. The real-time monitoring of these two sensors can provide the necessary data support for the controller 6, so that it can make corresponding adjustments according to the current environmental conditions; the sensor feeds back the measured data to the controller 6 to ensure that the device can respond to environmental changes in real time. This feedback mechanism enables the device to maintain optimal performance under different working conditions and avoid the decline in efficiency caused by environmental changes; the controller 6 instructs the driving member to rotate forward or reverse according to the data fed back by the sensor. When the motor reverses, the shovel blade 11 acts on the frost layer, which is suitable for areas with moderate frost layers; and when the motor rotates forward, the bending portion 12 acts on the frost layer, which is suitable for areas with thick frost layers. This intelligent control can select the most appropriate removal method according to the thickness and distribution of the frost layer; through the forward and reverse settings, the device can adopt different removal strategies for frost layers of different thicknesses. When the frost layer is moderate, the shovel blade 11 can effectively remove the frost layer and avoid damage caused by excessive removal; when the frost layer is thicker, the sharp design of the bend 12 can quickly cut into the frost layer to improve defrosting efficiency; this targeted removal method can reduce unnecessary energy consumption and avoid excessive operation of the equipment when dealing with the frost layer, thereby improving overall energy efficiency and reducing operating costs; the combination of real-time monitoring and intelligent control enables the equipment to operate in the best state, maintain high heat exchange efficiency, and ensure the stability of the dehumidification effect.

[0046] See also Figure 5In order to improve the dehumidification effect while reducing energy consumption, based on this, in one embodiment, a microchannel heat exchanger 13 is connected to the evaporator 2, a first pipe 14 is connected between the microchannel heat exchanger 13 and the compressor 9, a second pipe 15 is connected between the microchannel heat exchanger 13 and the roller 51, and a third pipe 16 is connected between the roller 51 and the compressor 9. The microchannel heat exchanger 13 can effectively recover the heat generated in the evaporator 2. When the first pipe 14 is opened, and the second pipe 15 and the third pipe 16 are closed, the heat in the microchannel heat exchanger 13 is recovered to the compressor 9 through the first pipe 14. This process can improve the overall energy efficiency of the system and reduce energy waste; through the recovered heat, the compressor 9 can work at a higher temperature, thereby improving its working efficiency. This heat recovery not only improves the performance of the equipment, but also reduces energy consumption, which is in line with the design concept of energy saving; when the first pipe 14 is closed, and the second pipe 15 and the third pipe 16 are opened, the heat in the microchannel heat exchanger 13 flows to the roller 51 through the second pipe 15 and the third pipe 16. This process transfers the heat of the roller 51 to the sponge 10, thereby melting the frost layer on the surface of the evaporator 2. By heating the roller 51, the defrosting efficiency can be effectively improved and the accumulation of the frost layer can be reduced; the heat transfer enables the sponge 10 to absorb the heat and transfer it to the frost layer, quickly melting the frost layer, avoiding the long downtime and increased energy consumption that may be caused by the traditional defrosting method; by transferring the heat to the roller 51 and then heating the sponge 10, the device can preheat the airflow at the air inlet 7 during the defrosting process. This design can increase the temperature of the air entering the device and improve the overall dehumidification efficiency of the device; the preheated airflow can increase its temperature before entering the evaporator 2, thereby reducing the burden on the evaporator 2, improving the heat exchange efficiency, and ensuring the stable operation of the device in a high humidity environment; through the recovery and reuse of heat, the device can reduce energy consumption while improving the dehumidification effect, thereby reducing the user's operating costs and improving economic benefits.

[0047] See also Figure 2 and Figure 3In order to ensure that the roller 51 is always in the best working position, the distance between the roller 51 and the evaporator 2 is automatically adjusted. Based on this, in one embodiment, an adjustment component 17 is also provided on the adjustment plate 52. The adjustment component 17 includes an adjustment rod 171, which is horizontally mounted on the adjustment plate 52. The adjustment rod 171 is set as a telescopic structure, and the roller 51 is rotatably mounted on the telescopic end of the adjustment rod 171. The telescopic structure of the adjustment rod 171 can realize automatic adjustment of the distance between the roller 51 and the surface of the evaporator 2. This automated design reduces the need for manual intervention, allowing the device to automatically adjust according to real-time environmental conditions and frost thickness, thereby improving the intelligence level of the device; through the feedback of the sensor or controller 6, the adjustment rod 171 can respond to the changes in the surface temperature and frost thickness of the evaporator 2 in real time to ensure that the roller 51 is always in the best working position; the distance between the roller 51 and the evaporator 2 is automatically adjusted to ensure the best contact between the roller 51 and the frost layer. This optimized contact can accelerate the melting of the frost layer, improve the defrosting efficiency, and reduce the time required for defrosting; the thickness and properties of the frost layer may be different in different working environments. The telescopic structure of the adjustment rod 171 can flexibly adapt to these changes, ensuring effective defrosting under various conditions; the thickness and properties of the frost layer may vary in different working environments. The telescopic structure of the adjustment rod 171 can flexibly adapt to these changes, ensuring effective defrosting under various conditions; reasonable distance adjustment can reduce the occurrence of equipment failures, ensure that the equipment operates in an efficient state, and improve overall reliability; an efficient defrosting process means that the equipment can return to normal working conditions more quickly, thereby reducing energy consumption caused by defrosting, and the automatic adjustment design can ensure that the equipment operates in an optimal state, further improving energy saving effects.

[0048] See also Figure 2 and Figure 3In order to adjust the angle between the roller 51 and the surface of the evaporator 2, reduce the time required for defrosting, and reduce the risk of physical damage to the evaporator 2, based on this, in one embodiment, the adjustment assembly 17 also includes an adjustment frame 172, which is hingedly mounted on the telescopic end of the adjustment rod 171, and the two ends of the roller 51 are rotatably mounted on the adjustment frame 172. The design of the adjustment frame 172 allows the angle between the roller 51 and the surface of the evaporator 2 to be adjusted. This angle optimization can ensure that the roller 51 is in more effective contact with the frost layer during the defrosting process, thereby improving the efficiency of defrosting; under different environmental conditions, the shape and thickness of the frost layer may be different. The setting of the adjustment frame 172 enables the device to flexibly respond to these changes and ensure that defrosting can be effectively performed under various conditions; by adjusting the angle between the roller 51 and the surface of the evaporator 2, the adjustment frame 172 can make the shovel blade 11 or the bent portion 12 form the best contact angle with the surface of the evaporator 2. This design can effectively remove the frost layer, reduce the residual frost layer, and improve the defrosting efficiency; the optimized angle adjustment can accelerate the melting and removal of the frost layer, reduce the time required for defrosting, and thus improve the overall working efficiency of the equipment; through reasonable angle adjustment, the adjustment frame 172 can avoid excessive contact between the roller 51 and the surface of the evaporator 2, reducing the risk of physical damage to the evaporator 2. This design can extend the service life of the equipment and reduce maintenance requirements; by reducing the defrosting time, the overall operating time of the equipment is optimized, reducing energy consumption and operating costs.

[0049] In order to avoid unnecessary energy consumption and optimize the defrosting process, based on this, in one embodiment, the controller 6 divides the measured temperature and humidity into the first level, second level, third level, and fourth level according to the preset intervals. When the surface temperature of the evaporator 2 is in the first level interval, the controller 6 instructs the driving member to reverse, and instructs the first pipe 14 to be connected, and the second pipe 15 and the third pipe 16 to be closed; when the surface temperature of the evaporator 2 is in the second level interval, the controller 6 instructs the driving member to rotate forward, and instructs the first pipe 14 to be connected, and the second pipe 15 and the third pipe 16 to be closed; when the surface temperature of the evaporator 2 is in the third level interval, the controller 6 instructs the driving member to reverse, and instructs the first pipe 14 to be closed, and the second pipe 15 and the third pipe 16 to be connected; when the surface temperature of the evaporator 2 is in the fourth level interval, the controller 6 instructs the driving member to rotate forward, and instructs the first pipe 14 to be closed, and the second pipe 15 and the third pipe 16 to be connected. Dividing the temperature and humidity into four levels enables the controller 6 to perform accurate management according to real-time environmental conditions. This hierarchical management can ensure that the equipment adopts the most appropriate operating strategy under different working conditions; the controller 6 can monitor the temperature of the surface of the evaporator 2 in real time, and dynamically adjust the rotation direction of the driving part and the opening and closing state of the pipeline according to the preset interval, so as to achieve fine control of the operating state of the equipment; in different temperature intervals, the controller 6 can instruct the driving part to reverse or forward, and optimize the defrosting process in combination with the opening and closing state of the pipeline. For example, in the first and second level intervals, the reversal or forward rotation of the driving part can effectively remove the frost layer, while in the third and fourth level intervals, changing the state of the pipeline can better manage the airflow direction and improve the defrosting efficiency; by timely adjusting the operating state of the equipment, the controller 6 can effectively reduce the accumulation of the frost layer, ensure that the evaporator 2 is always in the best working state, thereby improving the overall dehumidification efficiency; by dynamically adjusting the operating state of the equipment according to changes in temperature and humidity, the controller 6 can optimize energy consumption under different working conditions. For example, in the first and third level intervals where the temperature is lower, the controller 6 can select the reverse drive to reduce energy consumption; while in the second and fourth level intervals where the temperature is higher, the forward drive can improve work efficiency; through reasonable pipeline opening and closing control, unnecessary energy consumption is avoided, ensuring that the equipment only works when needed, thereby further reducing energy consumption; reasonable temperature and humidity control can reduce equipment wear, extend the service life of the equipment, and reduce maintenance costs.

[0050] See also Figure 6In order to improve the working efficiency of the evaporator 2 and reduce the fluctuation of the equipment performance caused by temperature changes, based on this, in one embodiment, a first condensation plate 18 is further arranged between the evaporator 2 and the air inlet 7, and the first condensation plate 18 is used to preheat the gas entering the equipment. The main function of the first condensation plate 18 is to preheat the gas entering the equipment. By heating the incoming cold air, the working efficiency of the evaporator 2 can be improved, so that the evaporator 2 can more effectively perform heat exchange when processing moisture; after preheating the gas, the energy required by the evaporator 2 is reduced, thereby reducing the overall energy consumption of the equipment. This design can reduce the burden of the compressor 9 to a certain extent and extend the service life of the equipment; the temperature of the preheated gas increases, which can increase its water content, so that the evaporator 2 can more effectively remove moisture from the air when processing moisture. This design can significantly improve the dehumidification efficiency of the equipment; by preheating the gas, the sudden drop in the surface temperature of the evaporator 2 can be reduced, thereby reducing the formation of the frost layer. This helps to maintain the normal working state of the evaporator 2, reduce the defrosting frequency, and improve the overall operating efficiency of the equipment; the setting of the first condensation plate 18 can enable the equipment to maintain a stable operating state under different environmental conditions. Preheating the gas can reduce fluctuations in equipment performance caused by temperature changes and ensure that the equipment operates in an efficient state; by preheating the incoming gas, the distribution of the airflow inside the equipment can be improved, ensuring that the gas flows more evenly between the evaporator 2 and the condenser 3, thereby improving the heat exchange efficiency.

[0051] See also Figure 6In order to ensure that the refrigerant is in a suitable state before entering the evaporator 2 and improve the heat exchange efficiency of the entire system, based on this, in one embodiment, a second condensation plate 19 and a third condensation plate 20 are also arranged between the evaporator 2 and the condenser 3. The compressor 9 compresses the refrigerant into the condenser 3. The refrigerant flows through the condenser 3 through the third condensation plate 20 to the first condensation plate 18, and flows from the first condensation plate 18 to the second condensation plate 19. The refrigerant flows from the second condensation plate 19 to the evaporator 2 through the liquid separation valve, and finally flows back to the compressor 9. The compressor 9 is responsible for compressing the refrigerant to a high-pressure state and sending it to the condenser 3. At this time, the temperature and pressure of the refrigerant are significantly increased and are in a gaseous state; the main function of the condenser 3 is to cool the high-temperature and high-pressure refrigerant and convert it into a liquid state. In the condenser 3, the refrigerant releases heat and lowers the temperature through heat exchange with the surrounding air or water; the refrigerant first flows through the condenser 3 and then enters the third condensation plate 20. The setting of the third condensation plate 20 can further reduce the temperature of the refrigerant, so that it has been partially cooled before entering the first condensation plate 18. This process improves the efficiency of heat exchange and ensures that the refrigerant is at a lower temperature when entering the first condensation plate 18; the cooled refrigerant then flows to the first condensation plate 18. Here, the refrigerant continues to release heat, further cools and converts into liquid. The design of the first condensation plate 18 enables the gas entering the device to exchange heat with the refrigerant more effectively after preheating; the liquid refrigerant flows from the first condensation plate 18 to the second condensation plate 19. The setting of the second condensation plate 19 can further optimize the flow and heat exchange process of the refrigerant, ensuring that the refrigerant has reached the optimal temperature and pressure state before entering the evaporator 2; the liquid refrigerant flows from the first condensation plate 18 to the second condensation plate 19. The setting of the second condensation plate 19 can further optimize the flow and heat exchange process of the refrigerant, ensuring that the refrigerant has reached the optimal temperature and pressure state before entering the evaporator 2; in the evaporator 2, the liquid refrigerant absorbs heat from the surrounding air and evaporates into a gaseous state. This process causes the moisture in the air to be condensed and discharged, thereby achieving a dehumidification effect. The design of the evaporator 2 ensures that the refrigerant can fully absorb heat and improve the dehumidification efficiency; the evaporated gaseous refrigerant eventually flows back to the compressor 9, completing a complete refrigeration cycle. The compressor 9 compresses the gaseous refrigerant again and enters the condenser 3 to start the next cycle.

[0052] The main function of the first condensation plate 18 is to perform heat exchange with the gas entering the device. By contacting the gas with the cooled liquid refrigerant, the first condensation plate 18 can effectively reduce the temperature of the gas and condense its moisture into water droplets, thereby achieving a dehumidification effect; when the refrigerant flows through the first condensation plate 18, the refrigerant continues to release heat, further reducing the temperature. This process ensures that the refrigerant is in a suitable state before entering the evaporator 2, thereby improving the working efficiency of the evaporator 2; the setting of the second condensation plate 19 further optimizes the flow and heat exchange process of the refrigerant. It ensures that the liquid refrigerant has reached the optimal temperature and pressure state before entering the evaporator 2, thereby improving the working efficiency of the evaporator 2; the setting of the second condensation plate 19 further optimizes the flow and heat exchange process of the refrigerant. It ensures that the liquid refrigerant has reached the optimal temperature and pressure state before entering the evaporator 2, thereby improving the working efficiency of the evaporator 2; the main function of the third condensation plate 20 is to preliminarily cool the refrigerant, so that its temperature has been partially reduced before entering the first condensation plate 18, thereby improving the overall heat exchange efficiency and ensuring that the refrigerant is at a lower temperature when entering the first condensation plate 18; by arranging the third condensation plate 20 between the condenser 3 and the first condensation plate 18, the heat exchange efficiency of the entire system can be effectively improved, and the heat loss of the refrigerant in the condenser 3 can be reduced, thereby improving the overall performance of the equipment.
