Description

Technical Field

[0001] This invention relates to the field of refrigeration devices, and more specifically, to a single-cooling type refrigeration device and refrigeration method. Background Technology

[0002] As an application of refrigeration design technology, refrigeration equipment mainly studies and selects main and auxiliary machines with matched performance, and connects them with different pipes to form refrigeration systems with different characteristics. It is a device closely integrated with multiple disciplines such as building, structure, water supply and drainage, heating and ventilation, mechanical transmission, electrical lighting, and automatic control, and is the crystallization of multidisciplinary research. With the continuous growth of the national economy, refrigeration equipment has been widely used in various aspects of industry, agriculture, commerce, science and technology, and people's lives, especially food refrigeration and air conditioning, which are directly related to the needs of industrial production and people's lives in many sectors.

[0003] In existing single-cooling refrigeration units, traditional mechanical bearings have physical contact with the main shaft, which generates varying degrees of frictional resistance during operation. Especially at high speeds, this frictional loss directly leads to a decrease in the actual working efficiency of the compressor.

[0004] To address the aforementioned technical issues, Chinese Patent CN102740225B discloses a single-cooling refrigeration device and method. By incorporating a magnetic levitation bearing assembly, the friction of traditional mechanical bearings is completely eliminated through the non-contact levitation of the radial magnetic bearing and the thrust bearing. Furthermore, real-time feedback from a displacement sensor between the radial magnetic bearing and the main shaft ensures stability of the main shaft during high-speed rotation, reducing vibration losses. However, in practical applications, the heat exchange efficiency of the condenser tube also needs optimization: a large amount of dust adheres to the tube wall surface, forming an insulation layer that significantly increases thermal resistance, worsens condensation efficiency, reduces cooling capacity, and increases energy consumption; uneven dust distribution leads to localized heat exchange failure, causing large fluctuations in condensing pressure and making the compressor prone to overload protection. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of this invention is to provide a single-cooling refrigeration device and refrigeration method.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A single-cooling refrigeration device includes a base, a bracket fixedly connected to the top edge of the base, a compressor fixedly connected to one side of the top of the base, a guide pipe fixedly connected to the output end of the compressor, a fan frame fixedly connected to the other side of the top of the base, a cooling fan fixedly connected to one side of the inside of the fan frame, a condenser tube fixedly connected to the other side of the inside of the fan frame, a throttling valve body connected to one end of the condenser tube, and an evaporator connected to the other end of the throttling valve body. The evaporator is connected to the input end of the compressor, and a descaling component for descaling the outer surface of the condenser tube is provided on one side of the fan frame.

[0008] The descaling assembly includes a first servo motor fixed to the front side of the fan frame and sliding grooves opened on the top and bottom of one side of the fan frame. The output end of the first servo motor is fixedly connected to a first threaded rod. A rectangular frame is slidably connected inside the sliding groove. A slider is slidably connected inside the rectangular frame. A rotating shaft is rotatably connected to one side of the slider. A sponge cleaning ring is fixedly connected to one side of the rotating shaft. A first internally threaded sleeve is fixedly connected to one side of the rectangular frame.

[0009] Furthermore, the sponge cleaning ring is sleeved on the outside of the condenser tube, the slider is I-shaped, the slider slides against the rectangular frame, the first internal threaded sleeve is connected to the first threaded rod by threads, and three of each of the slider, the rotating shaft and the sponge cleaning ring are provided.

[0010] Furthermore, the other end of the guide pipe is connected to one end of the condenser pipe, a dustproof net is provided on one side of the cooling fan, the cooling fan is located directly in front of the condenser pipe, and the other end of the condenser pipe extends out of the interior of the fan frame.

[0011] Furthermore, a speed-changing assembly for changing the airflow injection area is provided on the front and rear sides of the inner surface of the fan frame. The speed-changing assembly includes a second servo motor fixed on both sides of the top of the fan frame and eight guide plates rotatably connected to the front and rear sides of the inner surface of the fan frame. A worm gear is fixedly connected to one side of the guide plate, and a worm is fixedly connected to the output end of the second servo motor.

[0012] Furthermore, the guide plates are arranged in pairs, with each pair of guide plates being inclined. The two guide plates form a shape with one end having a larger opening and the other end having a smaller opening. The two guide plates are respectively fixedly connected to worm gears on opposite sides. The worm gears mesh with the worm. The guide plates are used to dynamically change the contraction area of ​​the air outlet to synchronously adjust the airflow velocity towards the condenser tube during the operation of the descaling component.

[0013] Furthermore, a wiping assembly is provided on the front and rear sides of the top of the base and around the compressor. The wiping assembly includes a third servo motor fixed on the front and rear sides of the top of the base. The output end of the third servo motor is fixedly connected to a second threaded rod. The outer surface of the second threaded rod is threadedly connected to a second internal threaded sleeve. A movable frame is fixedly connected to one side of the two second internal threaded sleeves that are close to each other. A wetting assembly is provided inside the movable frame.

[0014] Furthermore, the movable frame surrounds the outside of the compressor, the sponge is tightly attached to the outer surface of the compressor, and the sponge is located inside the movable frame.

[0015] Furthermore, the humidification component includes a water storage frame fixed to the top of the movable frame and two extrusion plates symmetrically fixed to one side of the support. The bottom of the water storage frame has a through hole, and the top of the water storage frame is symmetrically slidably connected to a telescopic rod around the central axis. The bottom of the telescopic rod is fixedly connected to a piston, and the outer surface of the telescopic rod is fitted with a spring. The tops of the two telescopic rods are fixedly connected to a ring.

[0016] Furthermore, the through hole penetrates the interior of the movable frame, the piston is located inside the through hole and is adapted to it, the top of the telescopic rod extends out of the water storage frame, the top of the spring is fixedly connected to the top of the water storage frame, and the bottom of the spring is fixedly connected to the top of the piston.

[0017] Preferably, it includes the following steps;

[0018] S1: Start the first servo motor to drive the first threaded rod to rotate in both directions. The first threaded rod drives the first internal threaded sleeve to move back and forth through the thread, thereby driving the rectangular frame to move back and forth inside the slide. The rectangular frame drives the sponge cleaning ring to slide on the outer surface of the straight section of the condenser tube through the slider and the rotating shaft until the sponge cleaning ring moves to the bend of the condenser tube.

[0019] S2: Then the first servo motor reverses, and then the rectangular frame moves in the opposite direction, driving the sponge cleaning ring back along the original path. This cycle repeats to wipe the surface of the condenser tube, improving the cleanliness of the straight section of the condenser tube.

[0020] S3: When the cooling fan delivers airflow to the condenser tube, the two guide plates guide the airflow delivered by the cooling fan. When the airflow enters the space formed by the two guide plates from the end with the larger opening and then flows out from the end with the smaller opening, the flow rate remains the same, but the outlet area decreases, which increases the flow velocity. Since the outlet is facing the condenser tube, the flow velocity around the condenser tube increases instantaneously, which can carry more heat in the same amount of time, further increasing the heat exchange effect of the condenser tube. Especially in hot weather, the cooling effect is better than that of traditional equipment.

[0021] S4: Start the third servo motor to drive the second threaded rod to rotate. The second threaded rod drives the moving frame to move upward through the second internal threaded sleeve. When the third servo motor flips, it drives the sponge to move downward. This cycle repeats. The sponge wipes the dust on the surface of the compressor to prevent too much dust from reducing the compressor's heat dissipation effect.

[0022] S5: The moving frame moves the water storage frame synchronously. As the water storage frame moves upward, the ring and the extrusion plate come into contact with each other. The extrusion plate prevents the ring from moving upward, causing the telescopic rod to slide relative to each other inside the water storage frame. The piston slides downward relative to each other inside the through hole, causing the piston to disengage from the through hole. At this time, the liquid inside the water storage frame flows into the moving frame from the through hole. The liquid wets the sponge, and the wet sponge wipes the surface of the compressor. This not only wipes away the dust more thoroughly, but also leaves water droplets on the surface of the compressor. Combined with the airflow delivered by the cooling fan, this accelerates the evaporation of water droplets on the surface of the compressor.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. This solution incorporates a descaling component. A rectangular frame moves back and forth inside a sliding groove. The frame, via a slider and a rotating shaft, drives a sponge cleaning ring to slide on the outer surface of the condenser tube. The frame then moves in the opposite direction, causing the sponge cleaning ring to return along the same path. This cycle repeats, wiping the surface of the straight section of the condenser tube. This prevents dust from forming an insulating layer on the condenser tube surface, avoids a significant increase in thermal resistance, ensures condensation efficiency, improves cooling capacity, prevents localized heat exchange failure, prevents condensation pressure fluctuations, and avoids damage to the compressor.

[0025] 2. This solution incorporates a speed-changing component. When the airflow enters the space formed by the two guide plates from the larger opening and then exits from the smaller opening, the flow rate remains constant while the outlet area decreases, resulting in increased flow velocity. Furthermore, since the outlet faces the condenser tube, the flow velocity around the condenser tube increases instantaneously, allowing it to carry more heat in the same amount of time. This further enhances the heat exchange effect of the condenser tube, especially in hot weather, where the cooling effect is better than traditional equipment. Additionally, the high-speed airflow can remove dust adhering to the surface of the condenser tube.

[0026] 3. This solution incorporates a humidification component. Liquid inside the water storage frame flows into the interior of the moving frame through the through-hole. The liquid wets the sponge. As the sponge slides up and down on the compressor surface, water droplets wipe the compressor surface, not only cleaning dust more thoroughly, but also leaving water droplets on the compressor surface. Combined with the airflow delivered by the cooling fan, this accelerates the evaporation of water droplets on the compressor surface, quickly absorbing heat from inside the compressor and further improving the compressor's cooling effect.

[0042] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0043] Please see Figures 1 to 8 A single-cooling refrigeration device includes a base 1, a bracket 2 fixedly connected to the top edge of the base 1, a compressor 3 fixedly connected to one side of the top of the base 1, a guide pipe 6 fixedly connected to the output end of the compressor 3, a fan frame 4 fixedly connected to the other side of the top of the base 1, a cooling fan 5 fixedly connected to one side of the inside of the fan frame 4, a condenser pipe 9 fixedly connected to the other side of the inside of the fan frame 4, a throttling valve body connected to one end of the condenser pipe 9, and an evaporator connected to the other end of the throttling valve body. The evaporator is connected to the input end of the compressor 3, and a descaling component 7 for descaling the outer surface of the condenser pipe 9 is provided on one side of the fan frame 4.

[0044] like Figures 3-4 As shown, the descaling assembly 7 includes a first servo motor 71 fixed to the front side of the fan frame 4 and a slide groove 74 opened on the top and bottom of one side of the fan frame 4. The output end of the first servo motor 71 is fixedly connected to a first threaded rod 72. A rectangular frame 75 is slidably connected inside the slide groove 74. A slider 76 is slidably connected inside the rectangular frame 75. A rotating shaft 79 is rotatably connected to one side of the slider 76. A sponge cleaning ring 77 is fixedly connected to one side of the rotating shaft 79. A first internal threaded sleeve 73 is fixedly connected to one side of the rectangular frame 75.

[0045] The sponge cleaning ring 77 is sleeved on the outside of the condenser tube 9. The slider 76 is I-shaped and slides against the rectangular frame 75. The first internal threaded sleeve 73 is connected to the first threaded rod 72 by threads. There are three sliders 76, three rotating shafts 79 and three sponge cleaning rings 77.

[0046] The other end of the guide pipe 6 is connected to one end of the condenser pipe 9. A dustproof net is provided on one side of the cooling fan 5. The cooling fan 5 is located directly in front of the condenser pipe 9. The other end of the condenser pipe 9 extends out of the interior of the fan frame 4.

[0047] When the refrigeration equipment is cooling, the condenser tube needs to exchange heat efficiently with the outside world, so that the high temperature and high pressure gas inside condenses into a low temperature liquid. The cooling fan 5 works and delivers a large amount of airflow to the condenser tube 9. The airflow will quickly carry away the heat from the condenser tube 9. When the surface of the condenser tube 9 is covered with dust, the heat exchange efficiency will decrease. At this time, the first servo motor 71 is started to drive the first threaded rod 72 to rotate in both directions. The first threaded rod 72 drives the first internal threaded sleeve 73 to move back and forth through the thread, thereby driving the rectangular frame 75 to move back and forth inside the slide groove 74. The length of the slide groove 74 and the stroke of the rectangular frame 75 are configured to match the length of the straight section of the condenser tube 9. In order to further ensure that the sponge cleaning ring 77 does not interfere with the bending of the condenser tube 9, the position and angle of the sponge cleaning ring can be finely adjusted at the bending point under the action of the slider 76 and the rotating shaft 79, so as to avoid the sponge cleaning ring 77 rigidly colliding with the bent tube, thereby ensuring that the sponge cleaning ring 77 will not get stuck at the bending point. The rectangular frame 75 drives the sponge cleaning ring 77 to slide on the outer surface of the straight section of the condenser tube 9 through the slider 76 and the rotating shaft 79. When the sponge cleaning ring 77 moves to the bend of the condenser tube 9, the first servo motor 71 reverses, and then the rectangular frame 75 moves in the opposite direction, driving the sponge cleaning ring 77 back along the original path. This cycle is repeated to wipe the surface of the condenser tube 9, preventing dust from forming a heat insulation layer on the surface of the condenser tube 9, avoiding a significant increase in thermal resistance, ensuring condensation effect, improving cooling capacity, avoiding local heat exchange failure, and preventing condensation pressure fluctuations.

[0048] like Figures 5-6 As shown, a speed-changing assembly 78 for changing the airflow injection area is provided on the front and rear sides of the inner surface of the fan frame 4. The speed-changing assembly 78 includes a second servo motor 781 fixed on both sides of the top of the fan frame 4 and eight guide plates 784 rotatably connected to the front and rear sides of the inner surface of the fan frame 4. A worm gear 783 is fixedly connected to one side of the guide plate 784, and a worm 782 is fixedly connected to the output end of the second servo motor 781.

[0049] The guide plates 784 are arranged in pairs, with each pair of guide plates 784 being inclined. The two guide plates 784 form a shape with one end having a larger opening and the other end having a smaller opening. The two guide plates 784 are respectively fixedly connected to worm gears 783 on opposite sides. The worm gears 783 and worm 782 mesh with each other. The guide plates 784 are used to dynamically change the contraction area of ​​the air outlet to synchronously adjust the airflow velocity towards the condenser tube 9 during the operation of the descaling component 7.

[0050] When the cooling fan 5 continuously blows air onto the condenser tube 9, the airflow speed around the condenser tube 9 is constant, and part of the airflow passes directly through the condenser tube 9 without participating in the heat exchange process. Therefore, it is necessary to guide the airflow from the cooling fan 5. When the cooling fan 5 delivers airflow to the condenser tube 9, the two second servo motors 781 drive the worm gears 782 to rotate. The two worm gears 782 respectively drive the worm wheels 783 on the two guide plates 784 to rotate. The worm wheels 783 drive the two guide plates 784 to rotate relative to each other in different directions, causing one end of the two guide plates 784 to move closer together. The two guide plates 784 guide the airflow delivered by the cooling fan 5. The airflow enters the space formed by the two guide plates 784 from the end with the larger opening and flows out from the end with the smaller opening. The flow rate remains the same, but the outlet area decreases, causing the flow velocity to increase. The large airflow, with its outlet facing the condenser tube 9, instantly increases the flow velocity around the condenser tube 9, allowing it to carry more heat in the same amount of time, further enhancing the heat exchange effect of the condenser tube 9. Especially in hot weather, the cooling effect is better than traditional equipment. The high-speed airflow, combined with the descaling component 7, can more thoroughly remove the dust adhering to the surface of the condenser tube 9. The cooled liquid enters the throttling valve body, forming a low-temperature, low-pressure gas-liquid mixture. The low-temperature, low-pressure liquid enters the evaporator, where it absorbs heat and evaporates, turning back into a low-temperature, low-pressure gas, which then returns to the compressor, completing the closed loop.

[0051] like Figure 7 As shown, a wiping assembly 8 is provided on the front and rear sides of the top of the base 1 and around the compressor 3. The wiping assembly 8 includes a third servo motor 81 fixed on the front and rear sides of the top of the base 1. The output end of the third servo motor 81 is fixedly connected to a second threaded rod 82. The outer surface of the second threaded rod 82 is threadedly connected to a second internal threaded sleeve plate 83. A movable frame 84 is fixedly connected to one side of the two second internal threaded sleeve plates 83 that are close to each other. A wetting assembly 85 is provided inside the movable frame 84. A wetting assembly 85 for wetting a sponge 86 is provided on the top of the movable frame 84.

[0052] The movable frame 84 surrounds the outside of the compressor 3, and the sponge 86 is tightly attached to the outer surface of the compressor 3, with the sponge 86 located inside the movable frame 84.

[0053] like Figure 2 and Figure 8 As shown, the humidification component 85 includes a water storage frame 851 fixed to the top of the movable frame 84 and two extrusion plates 857 symmetrically fixed to one side of the bracket 2. A through hole 856 is provided at the bottom of the water storage frame 851. A telescopic rod 853 is symmetrically slidably connected to the top of the water storage frame 851 around the central axis. A piston 855 is fixedly connected to the bottom of the telescopic rod 853. A spring 854 is sleeved on the outer surface of the telescopic rod 853. A ring 852 is fixedly connected to the top of the two telescopic rods 853.

[0054] The through hole 856 penetrates the interior of the movable frame 84, the piston 855 is located inside the through hole 856 and is adapted to it, the top of the telescopic rod 853 extends out of the interior of the water storage frame 851, the top of the spring 854 is fixedly connected to the top of the water storage frame 851, and the bottom of the spring 854 is fixedly connected to the top of the piston 855.

[0055] When the compressor is working, the internal heat of the compressor can easily lead to damage. The third servo motor 81 is activated, driving the second threaded rod 82 to rotate. The second threaded rod 82, through the second internal threaded sleeve 83, drives the moving frame 84 to move up and down, causing the water storage frame 851 to move synchronously. As the water storage frame 851 moves upward, the ring 852 and the pressing plate 857 simultaneously come into contact with each other. The two pressing plates 857 prevent the ring 852 from moving further upward. Two telescopic rods 853 symmetrically arranged at the bottom of the ring 852 stop the water storage frame 851 from moving upward. An internal synchronous guiding effect is formed, with the force direction consistent with the movement direction, resulting in vertical compression. This causes relative sliding between the telescopic rod 853 and the water storage frame 851. The piston 855 slides downwards relative to the inside of the through hole 856, causing the piston 855 to disengage from the inside of the through hole 856. At this time, the liquid inside the water storage frame 851 flows into the inside of the moving frame 84 through the through hole 856. The liquid wets the sponge 86, which wipes the surface of the compressor 3. This not only wipes away dust more thoroughly, but also leaves water droplets on the surface of the compressor 3. Combined with the airflow delivered by the cooling fan 5, this accelerates the evaporation of water droplets on the surface of the compressor 3, quickly absorbing the heat inside the compressor 3 and further improving the cooling effect of the compressor 3. When the ring 852 moves down and no longer contacts the extrusion plate 857, the spring 854 remains in contact with the piston 855. It provides vertical reset force, and the piston 854 and the through hole 856 are coaxially fitted. During the downward movement of the water storage frame 851, the piston 854 can automatically center and re-extend into the through hole 856 under the guidance of the spring force and the telescopic rod 853 to achieve a seal.

[0056] Refrigeration method of single-cooling refrigeration unit:

[0057] S1: Start the first servo motor 71 to drive the first threaded rod 72 to rotate forward and backward. The first threaded rod 72 drives the first internal threaded sleeve 73 to move back and forth through the thread, thereby driving the rectangular frame 75 to move back and forth inside the slide groove 74. The rectangular frame 75 drives the sponge cleaning ring 77 to slide on the outer surface of the straight section of the condenser tube 9 through the slider 76 and the rotating shaft 79 until the sponge cleaning ring 77 moves to the bend of the condenser tube 9.

[0058] S2: Then the first servo motor 71 reverses, and then the rectangular frame 75 moves in the opposite direction, driving the sponge cleaning ring 77 back along the original path. This cycle repeats to wipe the surface of the straight section of the condenser tube 9, improving the cleanliness of the surface of the condenser tube 9.

[0059] S3: When the cooling fan 5 delivers airflow to the condenser tube 9, the two guide plates 784 guide the airflow. When the airflow enters the space formed by the two guide plates 784 from the end with the larger opening and then flows out from the end with the smaller opening, the flow rate remains unchanged, but the outlet area decreases, which increases the flow velocity. Since the outlet is facing the condenser tube 9, the flow velocity around the condenser tube 9 increases instantaneously, allowing it to carry more heat in the same amount of time, further increasing the heat exchange effect of the condenser tube 9. Especially in hot weather, the cooling effect is better than that of traditional equipment.

[0060] S4: Start the third servo motor 81 to drive the second threaded rod 82 to rotate. The second threaded rod 82 drives the moving frame 84 to move upward through the second internal threaded sleeve plate 83. When the third servo motor 81 flips, it drives the sponge 86 to move downward. This cycle repeats. The sponge 86 wipes the dust on the surface of the compressor 3 to prevent excessive dust from reducing the heat dissipation effect of the compressor 3.

[0061] S5: The water storage frame 851 moves synchronously. As the water storage frame 851 moves upward, the ring 852 and the extrusion plate 857 come into contact with each other. The extrusion plate 857 prevents the ring 852 from moving upward, causing the telescopic rod 853 and the interior of the water storage frame 851 to slide relative to each other. The piston 855 slides downward relative to each other inside the through hole 856, causing the piston 855 to disengage from the interior of the through hole 856. At this time, the liquid inside the water storage frame 851 flows into the interior of the moving frame 84 through the through hole 856. The liquid wets the sponge 86. The wet sponge 86 wipes the surface of the compressor 3, which not only wipes away the dust more thoroughly, but also leaves water droplets on the surface of the compressor 3. Combined with the airflow delivered by the cooling fan 5, the water droplets on the surface of the compressor 3 evaporate faster.

10. A refrigeration method for a single-cooling type refrigeration device according to claim 1, characterized in that, Includes the following steps: S1: Start the first servo motor (71) to drive the first threaded rod (72) to rotate in both directions. The first threaded rod (72) drives the first internal threaded sleeve (73) to move back and forth through the thread, thereby driving the rectangular frame (75) to move back and forth inside the slide groove (74). The rectangular frame (75) drives the sponge cleaning ring (77) to slide on the outer surface of the straight section of the condenser tube (9) through the slider (76) and the rotating shaft (79) until the sponge cleaning ring (77) moves to the bend of the condenser tube (9). S2: Then the first servo motor (71) reverses, and then the rectangular frame (75) moves in the opposite direction, driving the sponge cleaning ring (77) back along the original path. This cycle is repeated to wipe the surface of the straight section of the condenser tube (9) to improve the cleanliness of the surface of the condenser tube (9). S3: When the cooling fan (5) delivers airflow to the condenser tube (9), the two guide plates (784) guide the airflow delivered by the cooling fan (5). When the airflow enters the space formed by the two guide plates (784) from the end with the larger opening and then flows out from the end with the smaller opening, the flow rate remains unchanged, the outlet area decreases, the flow velocity increases, and the outlet is facing the condenser tube (9), which makes the flow velocity around the condenser tube (9) increase instantly. In the same amount of time, it can carry more heat, further increasing the heat exchange effect of the condenser tube (9). Especially in hot weather, the cooling effect is better than that of traditional equipment. S4: Start the third servo motor (81) to drive the second threaded rod (82) to rotate. The second threaded rod (82) drives the moving frame (84) to move upward through the second internal threaded sleeve plate (83). When the third servo motor (81) flips, it drives the sponge (86) to move downward. This cycle repeats. The sponge (86) wipes the dust on the surface of the compressor (3) to avoid excessive dust reducing the heat dissipation effect of the compressor (3). S5: The moving frame moves and drives the water storage frame (851) to move synchronously. When the water storage frame (851) moves upward, the ring (852) and the extrusion plate (857) come into contact with each other. The extrusion plate (857) blocks the ring (852) from moving upward, so that the telescopic rod (853) slides relatively inside the water storage frame (851). The piston (855) slides relatively downward inside the through hole (856), so that the piston (855) disengages from the through hole (856). At this time, the liquid inside the water storage frame (851) flows into the moving frame (84) from the through hole (856). The liquid wets the sponge (86). The wet sponge (86) wipes the surface of the compressor (3), which not only wipes the dust more thoroughly, but also leaves water droplets on the surface of the compressor (3). Combined with the airflow delivered by the cooling fan (5), the water droplets on the surface of the compressor (3) are accelerated to evaporate.
