Description

Technical Field

[0001] The invention belongs to the technical field of air conditioning energy saving, in particular to a dual-frequency conversion machine room air conditioning unit and a control method thereof. Background Art

[0002] As the name implies, a dual-inverter computer room air conditioner is an air conditioner with two variable frequency components. It usually includes an indoor unit and an outdoor unit, both of which are equipped with variable frequency motors or compressors. This design enables the air conditioning system to more accurately adjust the cooling capacity and air supply volume, thereby achieving fine control of the temperature and humidity of the computer room:

[0003] The air conditioning unit is equipped with a filter inside to intercept impurities such as dust and hair in the air. As the air conditioning unit runs for a long time, tiny particles such as dust, hair, and dandruff in the air will be sucked into the filter. These particles gradually accumulate on the surface of the filter to form a thick dust layer, which blocks the filter. The amount of air entering the evaporator is reduced, and the heat exchange efficiency will decrease, resulting in poor cooling effect. The air conditioning unit needs to run for a longer time to reach the set temperature, which increases the running time of the compressor and thus increases energy consumption.

[0004] To this end, the present invention provides a dual-frequency conversion machine room air conditioning unit and a control method thereof. Summary of the invention

DETAILED DESCRIPTION

[0043] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0044] Embodiment 1: Figures 1 to 9 As shown, the dual-frequency conversion machine room air conditioning unit according to the embodiment of the present invention comprises an outdoor unit 1 and an indoor unit 2;

[0045] A filter 4 is provided inside the indoor unit 2, a cleaning block 5 is slidably mounted on the filter 4, the filter 4 is located between the cleaning blocks 5, an air nozzle 15 for spraying air toward the filter 4 is provided inside the cleaning blocks 5, and an atomizing nozzle 16 for spraying water mist toward the filter 4 is provided inside the cleaning blocks 5;

[0046] The filter 4 arranged inside the indoor unit 2 captures and filters the cold air or hot air after heat exchange, and can effectively filter and block tiny particles such as dust, hair, and dandruff in the air. When too much dust affects the circulation, the filter 4 can be cleaned by controlling the cleaning block 5 to slide on the surface of the filter 4.

[0047] The filter screen 4 is provided with a frame, the interior of the frame is the filter screen part, and the cleaning block 5 is wrapped around both sides of the filter screen 4, so when the cleaning block 5 slides on the surface of the filter screen 4, both sides of the filter screen 4 can be cleaned simultaneously.

[0048] The gas can be sprayed onto the surface of the filter screen 4 through the provided gas spray pipe 15, and the dust on the filter screen 4 can be blown off by the gas spraying.

[0049] A plurality of atomizing nozzles are provided at one end of the atomizing nozzle 16 facing the filter 4. The filter 4 can be rinsed by spraying water in atomized form. The filter 4 can be effectively cleaned by the cooperation of the air nozzle 15 and the atomizing nozzle 16, thereby ensuring the air output of the air conditioner, thereby reducing the time required for the air conditioner to reach the set temperature, and indirectly reducing the energy consumption of the air conditioner.

[0050] A liquid storage box 6 is disposed inside the indoor unit 2, and a first delivery component is disposed inside the indoor unit 2 for delivering the liquid inside the liquid storage box 6 to the atomizing nozzle 16;

[0051] The first delivery component can be used to deliver the liquid in the liquid storage box 6 to the inside of the atomizing nozzle 16 so as to flush the filter screen 4.

[0052] A second delivery assembly is provided inside the indoor unit 2 for delivering gas to the gas nozzle 15;

[0053] The gas can be delivered to the interior of the gas nozzle 15 by the second delivery assembly so as to facilitate the blowing treatment of the filter screen 4 .

[0054] A condensation pipe 3 is disposed inside the indoor unit 2 , and a storage chamber 14 is provided at one end of the cleaning block 5 away from the air spray pipe 15 . The cleaning block 5 is connected to the condensation pipe 3 through a discharge pipe 8 .

[0055] When the cleaning block 5 slides on the surface of the filter 4, the gas sprayed from the air nozzle 15 and the liquid sprayed from the atomizing nozzle 16 can penetrate the filter 4 and enter the interior of the storage chamber 14. The dust cleaned from the filter 4 can also be discharged from the discharge pipe 8 through the flow of liquid, and finally sent to the condenser 3 to be discharged together with the condensed water.

[0056] The first delivery assembly includes a liquid delivery pipe 13, a piston cylinder 20, a piston 23 and a liquid inlet pipe 21, wherein the piston cylinder 20 is fixedly installed inside the indoor unit 2, the piston 23 is slidably installed inside the piston cylinder 20, the liquid storage box 6 is connected to the piston cylinder 20 through the liquid inlet pipe 21, and the atomizing nozzle 16 is connected to the piston cylinder 20 through the liquid delivery pipe 13;

[0057] Both the liquid delivery pipe 13 and the liquid inlet pipe 21 are provided with a one-way valve.

[0058] The one-way valve disposed on the liquid delivery pipe 13 can only allow the liquid to be transported toward the inside of the atomizing nozzle 16 , and the one-way valve on the liquid inlet pipe 21 can only allow the liquid to be transported toward the direction of the liquid storage box 6 .

[0059] When the piston 23 slides in a direction away from the liquid delivery pipe 13, the liquid inside the liquid storage box 6 can be drawn into the interior of the piston cylinder 20 through the provided liquid inlet pipe 21. By controlling the piston 23 to slide in the direction of the liquid delivery pipe 13, the liquid in the piston cylinder 20 can be transported to the interior of the atomizing nozzle 16 through the liquid delivery pipe 13, and finally sprayed on the filter screen 4 to clean the filter screen 4.

[0060] The second delivery assembly includes an air intake pipe 22 and an air delivery pipe 12, one end of the air intake pipe 22 is connected to the piston cylinder 20, the other end of the air intake pipe 22 extends out of the outer wall of the indoor unit 2, and the air nozzle 15 is connected to the piston cylinder 20 through the air delivery pipe 12;

[0061] Both the air inlet pipe 22 and the air delivery pipe 12 are provided with a one-way valve;

[0062] The air inlet pipe 22 and the air delivery pipe 12 are arranged at one end of the piston cylinder 20 away from the liquid delivery pipe 13 and the liquid inlet pipe 21 .

[0063] The one-way valve provided on the air inlet pipe 22 can allow external gas to flow toward the inside of the piston cylinder 20 , and the one-way valve provided on the air supply pipe 12 can allow the gas in the piston cylinder 20 to flow toward the inside of the air nozzle 15 .

[0064] Therefore, when the piston 23 slides in the direction away from the air supply pipe 12, the air outside the indoor unit 2 can be sucked into the piston cylinder 20 through the air intake pipe 22. When the piston 23 slides in the direction of the air supply pipe 12, the gas in the piston cylinder 20 can be transported to the air nozzle 15 through the air supply pipe 12, and finally sprayed onto the filter 4 for cleaning.

[0065] When the piston 23 slides toward the liquid delivery pipe 13 , the piston 23 also slides in the direction away from the air delivery pipe 12 . When the piston 23 slides in the direction away from the liquid delivery pipe 13 , the piston 23 also slides in the direction of the air delivery pipe 12 .

[0066] Through the reciprocating sliding of the piston 23 , the air nozzle 15 and the atomizing nozzle 16 can cooperate with each other to clean the filter screen 4 , thereby further improving the cleaning effect of the filter screen 4 .

[0067] A flow tube 7 is fixedly connected to the condenser tube 3 , and the other end of the flow tube 7 extends to the inside of the liquid storage box 6 . The flow tube 7 is arranged obliquely.

[0068] One end of the flow tube 7 extends obliquely downward to the interior of the liquid storage box 6. When the indoor unit 2 works normally to produce condensed water, the condensed water will be discharged through the condensation tube 3. During the discharge process, some of the condensed water will flow into the interior of the liquid storage box 6 through the flow tube 7 for storage. When the condensed water level inside the liquid storage box 6 is higher than the flow tube 7, the condensed water can no longer continue to flow into the interior of the liquid storage box 6. The condensed water can be effectively utilized to flush the filter 4.

[0069] A driving motor 9 is fixedly installed inside the indoor unit 2 , and a first reciprocating screw 10 is fixedly connected to the output shaft of the driving motor 9 . The first reciprocating screw 10 passes through the cleaning block 5 and is threadedly connected to the cleaning block 5 .

[0070] The drive motor 9 can drive the first reciprocating screw 10 to rotate, thereby controlling the cleaning block 5 to slide back and forth on the surface of the filter 4. When the filter 4 inside the indoor unit 2 needs to be cleaned, the drive motor 9 is controlled to start.

[0071] A transmission rod 11 is rotatably installed inside the indoor unit 2 , and a second reciprocating screw rod 19 is slidably installed inside the transmission rod 11 . The other end of the second reciprocating screw rod 19 is fixedly connected to the piston 23 .

[0072] Through the rotation of the transmission rod 11, the second reciprocating screw 19 connected internally by a thread can be driven to slide back and forth inside the transmission rod 11, and the piston 23 can also be driven to slide back and forth inside the piston cylinder 20, and cooperate with the liquid delivery pipe 13 and the liquid inlet pipe 21 to clean the filter screen 4 with the condensed water inside the liquid storage box 6, and cooperate with the air intake pipe 22 and the air delivery pipe 12 to clean the filter screen 4 by gas delivery, thereby further improving the cleaning effect of the filter screen 4.

[0073] A conduction block 17 is slidably mounted on the outer wall of the transmission rod 11, and the conduction block 17 is fixedly connected to the cleaning block 5. A spiral groove is formed on the outer wall of the transmission rod 11, and a guide block 18 is fixedly mounted inside the conduction block 17, and one end of the guide block 18 extends into the interior of the spiral groove.

[0074] When the cleaning block 5 slides under the action of the driving motor 9 and the first reciprocating screw 10, the guide block 18 is driven to slide in the spiral groove on the transmission rod 11 through the conduction block 17, which can drive the transmission rod 11 to rotate. At this time, the second reciprocating screw 19 arranged inside the transmission rod 11 will drive the piston 23 to slide back and forth inside the piston cylinder 20.

[0075] Embodiment 2: Figures 10 to 12 As shown in Comparative Example 1, another embodiment of the present invention is:

[0076] An air outlet 30 is fixedly mounted on the air nozzle 15, and a brush plate 26 is slidably mounted inside the air outlet 30. The brush plate 26 is provided with bristles at one end facing the filter screen 4. Connecting rods 28 are fixedly mounted at both ends of the brush plate 26, and a return spring is provided between the connecting rod 28 and the air outlet 30.

[0077] The opening of the air outlet 30 changes from large to small, with the smaller end facing the filter 4. Therefore, when the air nozzle 15 sprays gas, the flow rate of the gas can be increased, thereby improving the cleaning effect of the filter 4. At the same time, the brush plate 26 can be set to further improve the cleaning effect of the filter 4 when the cleaning block 5 moves. The length of the combing hair set on the brush plate 26 can penetrate the filter 4. Therefore, when the cleaning block 5 drives the brush plate 26 to move, the brush plate 26 will drive the connecting rod 28 to rotate inside the air outlet 30 through the friction between the brush plate 26 and the filter 4, thereby generating a certain inclination. When the brush plate 26 is tilted, the bristles set on the brush plate 26 have the opportunity to penetrate the holes on the filter 4 while moving, thereby further improving the cleaning effect of the filter 4.

[0078] A rotating rod 25 is rotatably installed inside the air outlet 30, and a friction wheel 24 is fixedly installed on the top of the rotating rod 25. The outer wall of the friction wheel 24 fits with the frame of the filter screen 4, and the outer wall of the friction wheel 24 is set to a rough surface. A turntable 27 is fixedly installed on the end of the rotating rod 25 away from the friction wheel 24, and a top pressure wheel group 29 for pushing the connecting rod 28 to slide is fixedly installed on the top of the turntable 27.

[0079] When the cleaning block 5 slides on the surface of the filter screen 4, the friction wheel 24 will contact the frame of the surface of the filter screen 4, and the friction wheel 24 will drive the rotating rod 25 to rotate through the friction force. At this time, the rotating rod 25 will drive the turntable 27 and the pressing wheel group 29 to press the connecting rod 28. When the connecting rod 28 is pressed, the reset spring will also be deformed and store elastic potential energy. When the connecting rod 28 is not pressed, the reset spring releases the elastic potential energy and resets the connecting rod 28. A gap is left between the pressing wheel groups 29. The rotation of the pressing wheel group 29 can make the connecting rod 28 drive the brush plate 26 to slide back and forth up and down inside the air outlet 30, and the bristles can be used to further improve the cleaning effect of the filter screen 4.

[0080] The present invention also provides a control method for a dual-frequency conversion machine room air conditioner unit, the method adopts the above-mentioned dual-frequency conversion machine room air conditioner unit, and comprises the following steps:

[0081] S1: The indoor unit 2 performs cooling work, and the condensed water inside the condenser tube 3 enters the liquid storage box 6 through the flow tube 7 for storage;

[0082] S2: When the filter 4 needs to be cleaned, the first reciprocating screw 10 is controlled to rotate by the driving motor 9, so that the cleaning block 5 drives the conducting block 17 to slide on the transmission rod 11, and the transmission rod 11 is rotated by the guide block 18, and the second reciprocating screw 19 is controlled to slide, so that the piston 23 slides back and forth in the piston cylinder 20, and the condensed water in the liquid storage box 6 is transported to the atomizing nozzle 16 in cooperation with the liquid inlet pipe 21 and the liquid delivery pipe 13 to flush the filter 4, and then the gas is transported to the gas nozzle 15 through the air inlet pipe 22 and the air delivery pipe 12 to spray the filter 4;

[0083] S3: The cleaning block 5 drives the brush plate 26 to slide on the filter screen 4, and the friction wheel 24 drives the turntable 27 to rotate through the rotating rod 25. The reciprocating sliding of the brush plate 26 can be achieved through the cooperation of the top pressure wheel group 29 and the elastically arranged connecting rod 28.

[0084] Based on this, when the dual-frequency conversion room air conditioning unit provided by the present invention is working: the first reciprocating screw 10 is driven to rotate by the driving motor 9 to make the cleaning block 5 slide, and the guide block 18 is driven to slide in the spiral groove on the transmission rod 11 by the conduction block 17, so that the transmission rod 11 can be driven to rotate. At this time, the second reciprocating screw 19 arranged inside the transmission rod 11 will drive the piston 23 to slide back and forth inside the piston cylinder 20; when the piston 23 slides in the direction away from the liquid delivery pipe 13, the liquid inside the liquid storage box 6 can be drawn into the interior of the piston cylinder 20 through the arranged liquid inlet pipe 21, and when the piston 23 is controlled to slide in the direction of the liquid delivery pipe 13, the liquid in the piston cylinder 20 can be transported to the interior of the atomizing nozzle 16 through the liquid delivery pipe 13, and finally sprayed on the filter 4 to achieve the cleaning of the filter 4.

[0085] When the piston 23 slides in a direction away from the air supply pipe 12, the air outside the indoor unit 2 can be sucked into the piston cylinder 20 through the air intake pipe 22. When the piston 23 slides in the direction of the air supply pipe 12, the gas in the piston cylinder 20 can be transported to the air nozzle 15 through the air supply pipe 12, and finally sprayed on the filter 4 for cleaning. Through the cooperation of the air nozzle 15 and the atomizing nozzle 16, the cleaning effect of the filter 4 can be further improved to ensure the air output of the indoor unit 2, thereby reducing the time required for the air conditioner to reach the set temperature, and indirectly reducing the energy consumption of the air conditioner.

[0086] The cleaning block 5 is driven by the driving motor 9 to slide on the filter screen 4. At this time, the friction wheel 24 will contact the frame of the surface of the filter screen 4, and the friction wheel 24 will drive the rotating rod 25 to rotate through the friction force. At this time, the rotating rod 25 will drive the turntable 27 and the pressing wheel group 29 to press the connecting rod 28. When the connecting rod 28 is pressed, the reset spring will also be deformed and store elastic potential energy. When the connecting rod 28 is not pressed, the reset spring releases the elastic potential energy and resets the connecting rod 28. A gap is left between the pressing wheel groups 29. The rotation of the pressing wheel group 29 can make the connecting rod 28 drive the brush plate 26 to slide back and forth up and down inside the air outlet 30, and the bristles can be used to further improve the cleaning effect of the filter screen 4.
