[0046] Currently, magnetic levitation centrifugal compressors have eliminated the traditional oil lubrication system, using electromagnetic force to levitate the rotor for frictionless rotation, thus reducing energy consumption and noise caused by friction. Because no oil supply system is needed, costs are reduced. Therefore, magnetic levitation centrifugal compressors are widely used in various applications, such as air conditioning systems, leading to the increasingly widespread use of magnetic levitation air conditioning units.

[0047] The magnetic levitation air conditioning unit in the related technology includes a throttling element installed between the condenser and the evaporator, and a filter screen is provided at the refrigerant outlet of the condenser and inside the refrigerant pipeline near the throttling element to remove impurities or dust from the refrigerant.

[0051] Combination Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, this embodiment of the present disclosure provides a magnetic levitation air conditioning unit, including a condenser 100, an evaporator 200, a throttling element 300, a first refrigerant pipeline 410, and an electrostatic dust removal device 500.

[0054] An electrostatic dust removal device 500 is installed in the first refrigerant pipeline 410. The electrostatic dust removal device 500 can generate a positive or negative electric field so that the dust in the refrigerant flowing through the first refrigerant pipeline 410 is positively or negatively charged and is adsorbed to the bottom of the first refrigerant pipeline 410.

[0055] Optionally, the magnetic levitation air conditioning unit includes a condenser 100, an evaporator 200, a throttling element 300, and a magnetic levitation compressor. Optionally, the magnetic levitation compressor, condenser 100, throttling element 300, and evaporator 200 are sequentially connected via a refrigerant circulation pipeline to form a refrigerant circulation loop. Optionally, the magnetic bearings and positioning sensors of the magnetic levitation compressor utilize a CNC magnetic bearing system composed of radial and axial bearings made of permanent magnets and electromagnets to achieve frictionless movement of the compressor's moving parts suspended on a magnetic liner. The positioning sensors on the magnetic bearings provide ultra-high-speed real-time repositioning for the motor rotor to ensure precise positioning. The refrigerant is compressed into a high-temperature, high-pressure gaseous refrigerant in the magnetic levitation compressor and flows to the condenser 100, entering the interior of the condenser 100 through the first inlet 120. The gaseous refrigerant releases heat to the cooling water in the condenser 100 and condenses into a liquid refrigerant. The liquid refrigerant flows out of the condenser 100 through the first outlet 110 and then flows to the throttling element 300. The refrigerant is throttled and its pressure reduced by the throttling element 300. Afterward, it enters the evaporator 200 through the second inlet 210. Inside the evaporator 200, the liquid refrigerant absorbs heat from the chilled water and becomes gaseous again. This gaseous refrigerant then returns to the magnetic levitation compressor through the second outlet 220, where it is compressed again into high-temperature, high-pressure gaseous refrigerant. This completes the refrigerant cycle.

[0056] Optionally, the condenser 100 is a water-cooled condenser. The water-cooled condenser has a first heat exchange medium channel and a second heat exchange medium channel internally.

[0057] Optionally, the evaporator 200 is a water-cooled evaporator. The water-cooled condenser has a third heat exchange medium channel and a fourth heat exchange medium channel internally. The media in the third and fourth heat exchange medium channels exchange heat with each other when a temperature difference exists. In this embodiment, the third heat exchange medium channel is a refrigerant channel, and the fourth heat exchange medium channel is a chilled water channel. The refrigerant channel has a refrigerant inlet and a refrigerant outlet connected to the refrigerant circulation pipeline, wherein the second outlet 220 is the refrigerant outlet, and the second inlet 210 is the refrigerant inlet; the chilled water channel has a chilled water inlet and a chilled water outlet connected to the external cooling water circulation pipeline.

[0058] Optionally, a throttling element 300 is provided between the second inlet 210 of the evaporator 200 and the first outlet 110 of the condenser 100. The refrigerant circulation pipeline between the throttling element 300 and the first outlet 110 is the first refrigerant pipeline 410. To prevent dust and other impurities from being mixed in with the refrigerant flowing into the throttling element 300 through the first refrigerant pipeline 410, an electrostatic dust removal device 500 is provided on the first refrigerant pipeline 410.

[0059] Optionally, the electrostatic dust removal device 500 can generate an electric field to cause dust particles in the refrigerant flowing through the first refrigerant pipe 410 to acquire positive or negative charges and be adsorbed to the bottom of the first refrigerant pipe 410. This removes dust and other impurities from the refrigerant; even small dust particles can be adsorbed and collected, improving the dust removal effect on the refrigerant. Furthermore, it prevents dust and other impurities from clogging the pipes within the throttling element 300, improving the smoothness of refrigerant flow and the heat exchange efficiency of the magnetic levitation unit.

[0060] Optionally, the horizontally extending section of the first refrigerant pipe 410 is equipped with an electrostatic dust removal device 500.

[0061] The magnetic levitation air conditioning unit provided in this embodiment utilizes an electrostatic dust removal device installed on the first refrigerant pipeline. This device causes dust particles in the refrigerant flowing through it to acquire positive or negative charges, which are then adsorbed to the bottom of the first refrigerant pipeline. This effectively removes dust and other impurities from the refrigerant, preventing dust and impurities from clogging the throttling element, improving the dust removal efficiency of the refrigerant, enhancing the smoothness of refrigerant flow, and increasing the heat exchange efficiency of the magnetic levitation unit.

[0062] In some embodiments, the electrostatic dust removal device 500 includes an electromagnetic coil 510 and a plurality of first magnetic attractors 520.

[0063] An electromagnetic coil 510 is wound around the outer peripheral wall of the first refrigerant pipe 410. When alternating current is applied, it can generate a magnetic field. The peripheral wall of the first refrigerant pipe 410 can cut the magnetic field of the electromagnetic coil 510 to generate an electric field, so that the dust in the refrigerant can carry positive or negative charges after flowing through the electric field.

[0065] Optionally, the electromagnetic coil 510 is wound around the outer peripheral wall of the first refrigerant pipe 410. Thus, when alternating current is applied, the electromagnetic coil 510 can generate an alternating magnetic field. The peripheral wall of the first refrigerant pipe 410 can cut through the alternating magnetic field of the electromagnetic coil 510 to generate an electric field, causing dust in the refrigerant to carry a positive or negative charge after flowing through the electric field. The dust carrying a positive or negative charge can be attracted to the bottom of the first refrigerant pipe 410 by the first magnetic attractor 520 located at the bottom of the outer peripheral wall of the first refrigerant pipe 410, thereby removing dust and other impurities from the refrigerant.

In this way, the refrigerant containing dust first passes through the first section 411, which is wound with the first coil 511, so that some of the dust can be charged with positive or negative charges, and then it is attracted by the first magnetic attractor 520 disposed at the output end of the first section 411; then it passes through the second section 412, which is wound with the second coil 512, so that the remaining dust can be charged with positive or negative charges, and then it is attracted by the first magnetic attractor 520 disposed at the output end of the second section 412.

[0086] Optionally, if there is a large amount of dust collected inside the main body, the drain valve 631 can be opened to open the drain pipe 630. In this way, dust and other impurities can be discharged.

[0087] Optionally, the control device is electrically connected to the drain valve 631. Optionally, the control device can open or close the drain valve 631 at time intervals. For example, the drain valve 631 is opened at interval t3 and closed at interval t4.

[0094] Optionally, dust carrying positive or negative charges, when the first collection pipe 610 and / or the second collection pipe 620 are open, flows into the interior of the main body along with the refrigerant. Thus, refrigerant continuously accumulates inside the main body. Since the second magnetic suction member 640 is provided at the bottom of the main body, dust and other impurities can be attracted to the bottom of the main body, resulting in clean refrigerant in the upper layer inside the main body. Therefore, the second refrigerant pipe 420 is connected between the upper end of the main body and the condenser 100, allowing the refrigerant flowing into the dust collection device 600 to return to the condenser 100 through the second refrigerant pipe 420. Optionally, a refrigerant pump 700 is provided on the second refrigerant pipe 420. The refrigerant pump 700 provides the power to drive the refrigerant from the dust collection device 600 to the condenser 100, thereby improving the efficiency of refrigerant return to the condenser 100.

A refrigerant pump 700 is installed in the second refrigerant line 420 to provide the power to drive the refrigerant from the dust collection device 600 to the throttling element 300.

[0098] In some embodiments, the bottom wall of the output end of the first segment 411 is provided with a first recess 413, the bottom wall of the output end of the second segment 412 is provided with a second recess 414, the first collection pipe 610 is disposed in the first recess 413, and the second collection pipe 620 is disposed in the second recess 414.

[0099] Thus, as the refrigerant flows through the first section 411, it carries dust naturally towards the first recess 413, and as it flows through the second section 412, it carries dust naturally towards the second recess 414. Since both the output ends of the first section 411 and the second section 412 are equipped with first magnetic attractors 520, dust carrying positive or negative charges will be attracted to the bottom wall of the output end of the first section 411 or the bottom wall of the output end of the second section 412.

[0100] Since the sidewalls surrounding the first recess 413 are lower than the bottom wall of the surrounding first refrigerant pipe 410, and the sidewalls surrounding the second recess 414 are lower than the bottom wall of the surrounding first refrigerant pipe 410, the sidewalls connecting the bottom wall of the first refrigerant pipe 410 and the first recess 413 will act as a barrier to dust, improving the efficiency of dust flowing to the first collection pipe 610. Similarly, the sidewalls connecting the bottom wall of the first refrigerant pipe 410 and the second recess 414 will act as a barrier to dust, improving the efficiency of dust flowing to the second collection pipe 620.

[0101] In some embodiments, the magnetic levitation air conditioning unit further includes a drying and filtering device 800.

[0102] The first refrigerant pipeline 410 also includes a third section 415, which is connected between the first section 411 and the first outlet 110.

[0103] The drying and filtering device 800 is located in the third section 415 and is used to filter impurities carried in the refrigerant flowing out of the condenser 100 and / or adsorb residual moisture in the refrigerant.

[0104] Optionally, the magnetic levitation air conditioning unit also includes a drying and filtering device 800. The drying and filtering device 800 is located in the first refrigerant line 410 and includes a third section 415, specifically positioned between the condenser 100 and the first section 411 of the first refrigerant line 410. On one hand, the drying and filtering device 800 can initially filter dust and other impurities carried by the refrigerant during its flow, improving the removal efficiency; on the other hand, the drying and filtering device can adsorb residual moisture in the refrigerant.
