As shown in FIGS. 1-3 , an embodiment of the present disclosure provides an air conditioner flow divider, including a main flow line 1 , a multi-way flow flow line 2 , a magnetic flow regulator 4 , a magnet 3 and a controller 5 .

Wherein, the multi-way branch pipeline 2 communicates with one end of the main pipeline 1 . The magnetic flow regulator 4 is arranged between adjacent shunt pipelines 2, and is used to block part or all of the liquid inlet end of at least one shunt pipeline 2; the magnetic flow regulator 4 is connected to a power source, and is configured to generate magnetic. The magnet 3 is arranged on the outside of the shunt pipeline 2 and attracts or repels each other with the magnetism of the magnetic flow regulator 4 . The controller 5 is connected to the power supply 51 and is configured to control the movement of the magnetic regulator 4 by adjusting the current output by the power supply 51 to adjust the liquid inlet area corresponding to the liquid inlet end of the shunt pipeline 2 .

In this embodiment, the magnetic current regulating part 4 generates magnetism after being energized. If the magnetic current regulating part 4 moves under the gravitational force of the magnet 3, the power supply 51 is controlled so that the magnetism of the mutually attracting ends of the magnetic current regulating part 4 and the magnet 3 is different; if The magnetic current regulator 4 moves under the repulsive force of the magnet 3 , and the power source 51 is controlled to make the magnetism of the mutually repelling ends of the magnetic current regulator 4 and the magnet 3 the same. Taking Fig. 1 as an example, when the magnetic pole of the magnet 3 near the side of the shunt pipeline 2 is N pole, if the magnetic current regulator 4 moves to the left, the power supply 51 is controlled so that the left end polarity of the magnetic current regulator 4 is S pole, the magnetic current regulating part 4 moves to the left under the attraction of the magnet 3N pole; The flow member 4 moves to the right under the repulsive force of the N pole of the magnet 3. In this way, through the movement of the magnetic regulator 4 , the flow of the shunt pipeline can be adjusted.

Using the air conditioner flow divider provided by the embodiment of the present disclosure, a magnetic flow regulator 4 is arranged between adjacent flow distribution pipelines 2, and a magnet 3 and a controller 5 are arranged on the outside of the flow distribution pipeline 2; the refrigerant in the multi-way flow distribution pipeline In the case of uneven flow, control the movement of the magnetic regulator 4 corresponding to the diversion pipeline 2 with a large flow rate, and block the part of the liquid inlet end of the corresponding diversion pipeline 2 through the movement of the magnetic regulator 4, thereby reducing the corresponding flow rate. The liquid inlet area of the liquid inlet end of the shunt pipeline 2 realizes the adjustment of the refrigerant flow rate and improves the uniformity of the shunt flow of the shunt.

In some scenarios, the splitter of the air conditioner is not vertically installed, and the flow of the splitter will be uneven due to the gravity of the refrigerant itself; The liquid distribution of the split line is more uniform. In this embodiment, through the movement of the magnetic regulating member 4, it is possible to shield part or all of the liquid inlet ends of one branch pipeline 2, or partially shield the liquid inlet ends of two branch pipelines at the same time. The liquid inlet area of the two adjacent shunt pipes of the shunt is adjusted, and then the liquid splitting situation is adjusted to achieve the purpose of evenly splitting the refrigerant.

In this embodiment, the multi-way shunt pipeline refers to two or more shunt pipelines 2. Figure 1 shows a schematic structural diagram of two shunt pipelines, and Figure 2 shows a four-way shunt pipeline. Schematic.

Optionally, the magnetic current regulator 4 includes a conductor 42 and a wire 41, wherein the conductor 42 is arranged at the intersection of adjacent shunt pipelines 2; the wire 41 is wound on the surface of the conductor 41 and connected to a power source.

In this embodiment, the magnetic current regulator 4 includes a conductor 42 and a wire 41; after the wire wound on the surface of the conductor 41 is energized, the conductor 42 can generate magnetism; the magnetism of the conductor 42 depends on the winding direction of the wire and the direction of the energized current. When the shunt pipeline 2 is three or more, the air conditioner shunt includes a plurality of magnetic flow regulators 4, and when there are more than two magnetic flow regulators 4, based on the purpose of convenient control, multiple magnetic flow regulators 4 can be The winding directions of the wires 41 are set to be in the same direction.

Optionally, the magnet 3 includes two magnetic pieces respectively arranged on both sides of the shunt pipeline 2 .

In this embodiment, the number of magnets 3 can be one or two. In the case of a small number of shunt lines 2, a magnet 3 can be arranged on the outside of the multi-way shunt line 2; In some cases, a magnet 3 can be respectively arranged on both sides of the multi-channel shunt pipeline, so that the force of the magnet 3 and the magnetic regulator 4 can be ensured, and the control effect can be improved. In addition, when the magnets 3 are arranged on both sides of the shunt pipeline 2, the polarities of the two magnets 3 near the side of the shunt pipeline 2 can be the same or different; when the polarities are different, it is more helpful to control the movement of the magnetic regulator 4 . Fig. 1 shows a schematic structural diagram of magnets arranged on one side of the shunt pipeline, and Fig. 2 shows a schematic structural diagram of magnets with different polarities arranged on both sides of the shunt pipeline. As can be seen from the figure, the magnet 3 has two magnetic poles, the N pole and the S pole, and the N pole or the S pole of the magnet 3 is arranged on one side of the shunt pipeline 2, that is, a magnetic pole of the magnet 3 is close to the shunt pipeline 2; like this, It helps to enhance the interaction force between the magnet 3 and the magnetic current regulator 4 .

The air conditioner shunt of this embodiment, according to the winding direction of the wire 41 and the direction of the energized current; controls the magnetism of the magnetic flow regulator 4, and then controls the movement of the magnetic flow regulator 4, and adjusts the liquid inlet area of the liquid inlet end of the shunt pipeline 2 to realize refrigeration. The agent flow can be adjusted to improve the uniformity of the splitter.

As shown in FIG. 4 , an embodiment of the present disclosure provides a control method for an air conditioner splitter, including:

S101. Obtain the flow rate of the refrigerant at the liquid outlet of the multi-way diversion pipeline, and determine the target diversion pipeline whose flow rate exceeds the standard.

In this embodiment, a flow sensor or a flow meter may be respectively arranged at the liquid outlet end of each branch line to obtain the refrigerant flow rate at the liquid end of each branch line. The target shunt line whose flow exceeds the standard can be determined by setting the calibration value; or, the shunt line with the largest flow can be obtained by comparison, that is, the target shunt line whose flow rate exceeds the standard can be determined.

S102, controlling the movement of the magnetic flow regulator corresponding to the target diversion pipeline to adjust the liquid inlet area of the liquid inlet end of the target diversion pipeline.

In this embodiment, after the target flow diversion pipeline is determined, the movement of the magnetic flow regulator corresponding to the target flow diversion pipeline can be controlled. The specific control process is as follows: determine the magnetic current regulator, and then clarify the moving direction of the magnetic current regulator; determine the magnetism of the magnetic current regulator based on the magnetism outside the shunt pipeline; combine the winding direction of the wire in the magnetic current regulator and the power supply The direction of the current makes the magnetic flow regulator generate corresponding magnetism; in this way, through the movement of the magnetic flow regulator corresponding to the target shunt pipeline, the part of the liquid inlet end of the shunt pipeline is blocked, so as to adjust the liquid inlet of the target shunt pipeline The adjustment of the area can improve the problem of uneven flow in the shunt pipeline. Take Figure 1 as an example to illustrate, assuming that the shunt pipeline on the left side of Figure 1 is controlled as the target pipeline, the corresponding magnetic flow regulator needs to be controlled to move to the left to adjust the liquid inlet area of the shunt pipeline; at this time, The magnet near the side of the shunt pipeline is the N pole. After the magnetic current regulator is energized, the left end of the magnetic current regulator conductor needs to be the S pole. Determine the current direction of the power supply according to the winding direction of the guide, so that the left end of the magnetic current regulator is S. The magnetism of the poles attracts each other with the magnet to realize the movement of the magnetic current regulator.

Here, the determination of the magnetic flow regulator can be determined by the position of the target shunt pipeline; for example: when the target shunt pipeline is on the side, there is only one magnetic flow regulator corresponding to the target shunt pipeline, and the magnetic flow regulator is clear; When the target shunt line is in a non-side road, there may be two magnetic flow regulators corresponding to the target flow line. At this time, one of the magnetic flow regulators can be determined according to the actual situation or preset conditions for control; the preset conditions can be It is to control the magnetic current regulating part on the left or the right side, or it may be to determine the magnetic current regulating part according to the distance between the magnetic current regulating part and the magnet.

In addition, the liquid inlet area of the target shunt pipeline can be adjusted by controlling the moving distance of the magnetic flow regulator; or, the liquid inlet area of the target shunt pipeline can be adjusted by controlling the power-on time of the magnetic flow regulator.

Using the control method for the air-conditioning shunt provided by the embodiment of the present disclosure, based on the principle of electromagnetic induction, the movement of the magnetic flow regulating member that can generate magnetism is controlled when the power is applied, thereby changing the size of the liquid inlet area of the target shunt pipeline. In this way, the shunt is realized The adjustment of the refrigerant flow rate improves the uniformity of the split flow of the separator.

Optionally, controlling the movement of the magnetic current regulator corresponding to the target shunt pipeline includes controlling the current output by the power supply and adjusting the moving distance of the magnetic current regulator.

In this embodiment, the magnitude and duration of the output current of the power supply affect the magnetic field of the magnetic current regulating element, thereby affecting the moving speed of the magnetic current regulating element, resulting in different moving distances of the magnetic current regulating element per unit time. Therefore, adjusting the liquid inlet area of the target shunt pipeline can be realized by controlling the moving distance of the magnetic current regulator according to the current output by the control power supply.

Optionally, the moving distance of the magnetic current regulating member corresponding to the target shunt line is determined according to the electrification duration of the magnetic current regulating member and/or the magnitude of the current.

In this embodiment, the electrification duration of the magnetic current regulating element reflects the time period during which the magnetic current regulating element generates magnetism. The magnetic current regulator is magnetic, which is the prerequisite for the movement of the magnetic current regulator; therefore, under the condition of constant energized current, the duration of the magnetic current regulator determines the moving distance of the magnetic current regulator.

The magnitude of the energizing current of the magnetic current regulator reflects the strength of the magnetism generated by the magnetic current regulator. The larger the current, the stronger the magnetic field of the magnetic current regulator. The faster the moving speed affects the moving distance of the magnetic regulator.

As shown in FIG. 5 , an embodiment of the present disclosure provides another control method for an air conditioner splitter, including:

S201. Obtain the flow rate of the refrigerant at the liquid outlet of the multi-way diversion pipeline, and determine the flow scalar according to the number of the diversion pipelines.

In this embodiment, the flow scalar refers to a calibration value for judging the flow rate of each shunt line. For example, compare the flow of each shunt line with the flow scalar. If the flow value is greater than the flow scalar, then the shunt is considered The road traffic exceeds the standard. Usually, the flow scalar is obtained according to the number and total flow of the shunt pipelines, that is, the flow scalar = total flow/number of shunt pipelines; the total flow can be obtained by detecting the flow of the main flow pipeline, or by accumulating multiple shunt pipelines The sum of the flows is obtained.

S202 , judging whether the difference between the refrigerant flow rate at the liquid outlet end of the distribution pipeline and the flow rate scalar meets an exceeding condition.

S203, if it is satisfied, determine the diversion pipeline with the largest flow rate among the multi-channel diversion pipelines as the target diversion pipeline.

In this embodiment, the over-standard condition can be a set value or a set interval; for example, the difference between the refrigerant flow rate at the liquid outlet end of the split pipeline and the flow scalar value is non-zero, that is, the over-standard condition is the The flow rate is not equal to the flow scalar; or, the difference between the refrigerant flow at the liquid outlet of the shunt pipe and the flow scalar is greater than the set threshold, that is, the exceeding standard condition is that the flow of the shunt pipe is not equal to the flow scalar, and the difference is greater than Set the threshold.

After determining the diversion pipeline that meets the exceeding standard condition, if the number of diversion pipeline meeting the exceeding standard condition is one, then the diversion pipeline is the target diversion pipeline; if the number of diversion pipelines meeting the exceeding standard condition is more than two, confirm The diversion pipeline with the largest flow among the diversion pipelines satisfying the exceeding standard condition is the target diversion pipeline.

Optionally, the over-standard condition is determined according to the number of shunt pipes; when the number of shunt pipes is 2, the over-standard condition is that the difference between the refrigerant flow at the liquid end of the shunt pipe and the flow scalar value is not zero; When the number of pipelines is greater than 2, the exceeding standard condition is that the difference between the refrigerant flow at the liquid outlet end of the split pipeline and the flow scalar value is greater than the set threshold.

In this embodiment, the basis for setting the exceeding standard condition is the number of shunt pipelines; when the number of shunt pipelines is 2, the exceeding standard condition is that the difference between the flow rate of the shunt pipeline and the flow scalar value is not zero, that is, it is judged that the shunt is diverted Whether it is uniform or not, according to the difference between the flow of the shunt pipeline and the flow scalar value, when there is a difference, it means that the flow of the two shunt pipelines is different, and the flow of the shunt is not uniform. In addition, when the number of shunt pipes is 2, the flow of the two shunt pipes can be directly compared to determine whether the flow of the shunt is uniform, without judging based on the flow scalar and exceeding the standard.

When the number of shunt pipes is greater than 2, the exceeding condition is that the difference between the flow of the shunt pipe and the flow scalar is greater than the set threshold; that is, when the number of shunt pipes is large, whether the flow of the shunt is uniform refers to the flow rate of each shunt pipe. Whether the flow change is within the set range, if it exceeds the set range, it is determined that the flow of the splitter is uneven; therefore, when the number of shunt pipelines is large, the exceeding condition can be a set range, not limited to a fixed value.

S204, controlling the movement of the magnetic regulating member corresponding to the target diversion pipeline, so as to adjust the liquid inlet area of the liquid inlet end of the target diversion pipeline.

Optionally, controlling the movement of the magnetic flow regulator corresponding to the target shunt pipeline includes: controlling the movement of the magnetic flow regulator when one side of the target shunt pipeline is provided with a magnetic flow regulator; In the case where magnetic current regulating parts are provided on both sides, the movement of any magnetic current regulating part is controlled, or the movement of the magnetic current regulating part closest to the magnet is controlled.

In this embodiment, if only one side of the target shunt pipeline is provided with a magnetic flow regulating member, then the magnetic flow regulating piece corresponding to the target shunt pipeline is unique, and only the movement of the magnetic flow regulating piece can be controlled. If there are magnetic flow regulators on both sides of the target shunt pipeline, you can choose to control the movement of the magnetic flow regulator with the closest distance according to the distance between the magnetic flow regulator and the magnet. Or, if there are magnets on both sides of the shunt pipeline, a magnetic flow regulating piece corresponding to the control target shunt pipeline can also be randomly selected; or, the target shunt pipeline can be controlled to be fixed Magnetic current regulator on the direction side (eg left). In this way, the magnetic current regulator can be selected flexibly, and the control effect is guaranteed.
