The structure of the first one-way throttle valve 7 and the flow process of refrigerant in the first one-way throttle valve 7 will be described in detail below by taking the first one-way throttle valve 7 as an example. It should be noted that the structure of the second one-way throttle valve 8 is the same as that of the first one-way throttle valve 7, and the working principle of the second one-way throttle valve 8 is the same as that of the first one-way throttle valve 7. The working principle is the same, and will not be described in detail here.

As shown in FIG. 2 , the first one-way throttle valve 7 may include: a housing 163 , a valve core 164 and a movable part 165 . Wherein, the casing 163 has a chamber 1631 inside, and the valve core 164 is disposed in the chamber 1631 . The spool 164 has a channel 1641 communicating with the chamber 1631. The first end of the channel 1641 is located adjacent to the first valve port m, and the second end of the channel 1641 is located adjacent to the second valve port n. The channel 1641 includes a first section 1642 and a second section 1643 communicating with the first section 1642. The cross-sectional area of the first section 1642 is smaller than that of the second section 1643. There is a gap between the outer peripheral wall of the second section 1643 and the inner wall of the cavity 1631 , and a plurality of communication holes 1644 communicating with the cavity 1631 are provided on the side wall of the second section 1643 . Preferably, the sum of cross-sectional areas of the plurality of communicating holes 1644 is greater than or equal to the cross-sectional area of the second section 1643 . The movable part 165 is slidably disposed in the second section 1643 to open or close the communicating hole 1644 , and the outer peripheral wall of the movable part 165 is attached to the inner wall of the second section 1643 . The movable part 165 is provided with a throttling passage 1651, the first end of the throttling passage 1651 is arranged at a position adjacent to the first valve port m, and the second end of the throttling passage 1651 is arranged at a position adjacent to the second valve port n , the cross-sectional area of the throttle channel 1651 is much smaller than the cross-sectional area of the second segment 1643 . When the movable part 165 moves to a position adjacent to the second valve port n, the movable part 165 opens the communication hole 1644, and the second section 1643 of the channel 1641 can communicate with the chamber 1631 through the communication hole 1644; When the valve port is at a position of m, the movable part 165 closes the communication hole 1644 , the passage 1641 cannot communicate with the chamber 1631 through the communication hole 1644 , and the passage 1641 communicates with the chamber 1631 through the throttling passage 1651 .

When the refrigerant flows from the first valve port m to the second valve port n, in the direction shown by the arrow A in Figure 2, the refrigerant enters the chamber 1631 from the first valve port m, and then flows through the channel 1641 of the valve core 164. The first end enters the first section 1642 of the channel 1641, and under the push of the refrigerant, the movable part 165 moves in the direction indicated by the arrow A in the second section 1643, and the movable part 165 opens the communication hole 1644, and the refrigerant is released from the second section 1643. After one section 1642 enters the second section 1643, it enters into the chamber 1631 through the communication hole 1644. At this time, the first one-way throttle valve 7 only acts as a connecting pipe, that is, the pressure at both ends of the passage 1641 is roughly equal; when the refrigerant When flowing from the second valve port n to the first valve port m, the refrigerant enters the chamber 1631 from the second valve port n in the direction shown by arrow B in FIG. end into the second section 1643 of the channel 1641, under the push of the refrigerant, the movable part 165 moves in the direction shown by the arrow B in the second section 1643, the movable part 165 closes the communication hole 1644, and the refrigerant flows from the chamber 1631 After entering the second segment 1643, it enters the first segment 1642 through the throttling passage 1651, and then flows out from the first end of the passage 1641 into the chamber 1631. Since the cross-sectional area of the throttling passage 1651 is much smaller than that of the second The cross-sectional area of the section 1643 and the pressure difference between the two ends of the channel 1641 are relatively large, and at this time the first one-way throttle valve 7 plays a throttling role.

The following describes the working process of the air conditioner 100 according to the embodiment of the present utility model with reference to FIG. 1 .

When the air conditioner 100 is in cooling mode, the first port c of the reversing assembly 2 communicates with the second port d and the third port e communicates with the fourth port f, the first control valve 5 is in an open state, and the second control valve 12 Can be on or off. It should be noted that when the first control valve 5 is an electronic expansion valve, in the refrigeration mode, the opening of the first control valve 5 should be relatively large so that the first control valve 5 acts as a throttling and depressurization function or throttling The depressurization effect is small, which ensures that the temperature difference between the refrigerant flowing out of the first control valve 5 and the refrigerant flowing out of the outdoor heat exchanger 3 is small.

As shown by the solid arrow in Figure 1, the refrigerant discharged from the exhaust port a of the compressor 1 flows into the outdoor heat exchanger 3 through the first port c and the second port d to condense, and the refrigerant discharged from the outdoor heat exchanger 3 The refrigerant enters the first one-way throttle valve 7 through the first valve port m, and at this time, the first one-way throttle valve 7 is fully connected and functions as a connecting pipe.

When the second control valve 12 is in the open state, the refrigerant flowing out from the second valve port n is divided into two parts, and part of the refrigerant flows from the fourth valve port j to the second one-way throttle valve 8 through the second refrigerant flow path 10 Another part of the refrigerant flows into the cooling assembly 61 through the first control valve 5 to dissipate heat from the electronic control element 60 , and the refrigerant flowing out of the cooling assembly 61 flows into the second one-way throttle valve 8 from the fourth valve port j. That is to say, the two parts of refrigerant merge in the second one-way throttle valve 8 . When the second control valve 12 is in the closed state, all the refrigerant flowing out from the second valve port n enters the first refrigerant flow path 9, and the refrigerant flows into the heat dissipation assembly 61 through the first control valve 5 to heat the electric control element 60. To dissipate heat, the refrigerant flowing out from the heat dissipation assembly 61 is discharged into the second one-way throttle valve 8 .

Since the second one-way throttle valve 8 is a throttling component in the flow direction from the fourth valve port j to the third valve port h, the refrigerant flowing into the second one-way throttle valve 8 is Throttling and depressurization are carried out in the throttle valve 8.

The refrigerant discharged from the second one-way throttle valve 8 is discharged into the indoor heat exchanger 4 to cool the indoor environment, and the refrigerant discharged from the indoor heat exchanger 4 passes through the third port e, the fourth port f and the air return port b is discharged back to compressor 1 to complete the refrigeration cycle.

When the air conditioner 100 is in the cooling mode, since the temperature of the refrigerant discharged from the outdoor heat exchanger 3 is slightly higher than the ambient temperature, when the refrigerant with a temperature slightly higher than the ambient temperature flows through the cooling assembly 61, the electric control element 60 can be To dissipate heat and effectively prevent the generation of condensed water.

When the air conditioner 100 is in the heating mode, the first port c of the reversing assembly 2 communicates with the third port e and the second port d communicates with the fourth port f, the second control valve 12 is in an open state, and the first control valve 5 can be in the closed state or the open state. As shown by the dotted arrow in Figure 1, the refrigerant discharged from the exhaust port a of the compressor 1 is discharged into the indoor heat exchanger 4 through the first port c and the third port e for condensation, and the refrigerant discharged from the indoor heat exchanger 4 The discharged refrigerant is discharged into the second one-way throttle valve 8 from the third valve port h, because the second one-way throttle valve 8 is completely connected in the flow direction from the third valve port h to the fourth valve port j , so the second one-way throttle valve 8 acts as a connecting pipe.

When the first control valve 5 is in the closed state, the refrigerant discharged from the second one-way throttle valve 8 enters the first one-way throttle valve 7 through the second refrigerant flow path 10 and the second valve port n.

When the first control valve 5 is in the open state, the refrigerant discharged from the second one-way throttle valve 8 is divided into two parts, and one part is discharged into the first one-way throttle through the second refrigerant flow path 10 and the second valve port n. In the valve 7, another part of the refrigerant enters the first refrigerant flow path 9, and this part of the refrigerant flows into the heat dissipation assembly 61 to dissipate heat from the electronic control element 60, and the refrigerant flowing out from the heat dissipation assembly 61 passes through the first control valve 5 and the second control valve 5. Port n discharges into the first throttle check valve 7 .

Since the first one-way throttle valve 7 is a throttling component in the flow direction from the second valve port n to the first valve port m, the refrigerant is throttled and depressurized in the first one-way throttle valve 7, from The refrigerant discharged from the first one-way throttle valve 7 enters the outdoor heat exchanger 3 for evaporation, and the refrigerant discharged from the outdoor heat exchanger 3 is discharged back to the compressor through the second port d, the fourth port f and the air return port b 1, complete the heating cycle.

When the air conditioner 100 is in the heating mode, since the temperature of the refrigerant discharged from the indoor heat exchanger 4 is slightly higher than the ambient temperature, even when the first control valve 5 is in an open state, the refrigerant flow whose temperature is slightly higher than the ambient temperature The heat dissipation component 61 can dissipate heat from the electronic control element 60 and effectively prevent the generation of condensed water, thereby ensuring the reliability of the electronic control element 60 during the heating operation of the air conditioner 100 .

When the air conditioner 100 is heating and defrosting, since the temperature of the refrigerant flowing out of the outdoor heat exchanger 3 is very low at the initial stage of defrosting, in this case, the refrigerant flowing through the heat dissipation assembly 61 will produce thermal shock to the electronic control element 60 . Therefore, preferably, when the air conditioner 100 is in the heating and defrosting mode, at the beginning of the heating and defrosting, the first control valve 5 is in the closed stage, so that at the beginning of the defrosting, when the temperature of the refrigerant is low, the first control valve 5 is closed. A control valve 5 prevents the refrigerant from flowing through the first refrigerant flow path 9 , and the refrigerant completely flows through the second refrigerant flow path 10 , which means that the refrigerant does not flow through the heat dissipation assembly 61 to prevent the refrigerant from heating and cooling the electronic control element 60 impact and affect the service life of the electronic control element 60. When the air conditioner 100 is in the defrosting mode, the first port c of the reversing assembly 2 communicates with the second port d and the third port e communicates with the fourth port f. It should be noted that in the defrosting stage, the closing time of the first control valve 5 can be specifically set according to the actual situation, which is not limited here.

It can be understood that, when the air conditioner 100 is heating and defrosting, the second control valve 12 should always be in an open state.

According to the air conditioner 100 of the embodiment of the present utility model, by being provided with the first one-way throttle valve 7, the second one-way throttle valve 8, the first control valve 5, the second control valve 12 and the cooling assembly 61, the cooling In this mode, the cooling medium whose temperature is close to or slightly higher than the ambient temperature can flow through the cooling assembly 61 to dissipate heat from the electronic control element 60 . This can effectively dissipate heat to the electronic control element 60 without reducing the operating frequency of the compressor 1 (even in the case of high ambient temperature), thereby ensuring Cooling effect, improve user comfort.

Moreover, since the temperature of the refrigerant flowing into the cooling assembly 61 is close to or slightly higher than the ambient temperature, it is possible to avoid generating condensation water on the electric control element 60 and to drop the temperature of the electric control element 60 too low, thereby improving the performance of the electric control element. Component 60 reliability and safety. In the heating mode, when the first control valve 5 is opened, the temperature of the refrigerant entering the electric control element 60 is close to or slightly higher than the ambient temperature, which can avoid the generation of condensation water on the electric control element 60 and the electric control element 60. The temperature drop of the element 60 is too low. When the first control valve 5 is closed, the refrigerant discharged from the second one-way throttle valve 8 is discharged into the outdoor heat exchanger 3 through the second refrigerant flow path 10, which can prevent condensation The generation of water ensures the reliability of the electric control element 60 during the heating operation of the air conditioner 100 .

As shown in FIG. 1 , in a preferred embodiment of the present invention, the reversing assembly 2 is a four-way valve. Of course, it can be understood that the structure of the reversing assembly 2 is not limited thereto. The reversing assembly 2 may include a first pipeline to a fourth pipeline, the first pipeline to the fourth pipeline are connected end to end in sequence, and the first pipeline is connected in series with a first channel An off valve, a second on-off valve is connected in series on the second pipeline, a third on-off valve is connected in series on the third pipeline, a fourth on-off valve is connected in series on the fourth pipeline, the connection between the first pipeline and the second pipeline is defined Out of the first port c, the connection of the first pipeline and the fourth pipeline defines the second port d, the connection of the fourth pipeline and the third pipeline defines the fourth port f, the connection of the third pipeline and the second pipeline A third port e is defined, the first on-off valve and the third on-off valve are opened or closed simultaneously, and the second on-off valve and the fourth on-off valve are opened or closed simultaneously.

As shown in FIG. 3 and FIG. 4 , according to an embodiment of the present invention, the heat dissipation assembly 61 may include: a heat dissipation pipe 601 and a heat dissipation shell 602 . Preferably, the heat dissipation pipe 601 is a copper pipe. Thereby, the heat exchange efficiency of the heat radiation pipe 601 can be improved. Wherein, the heat dissipation pipe 601 is connected in series on the first refrigerant flow path 9 , and the refrigerant can flow in the heat dissipation pipe 601 . The heat dissipation pipe 601 is arranged on the heat dissipation shell 602 , and the heat dissipation shell 602 is in contact with the electronic control element 60 for dissipating heat from the electric control element 60 . Thus, the heat dissipation efficiency of the heat dissipation assembly 61 can be improved, and the operation stability of the electronic control element 60 can be ensured.

Further, the heat dissipation case 602 may include: a heat dissipation substrate 6020 and a fixed baffle 6021 . Wherein, the heat dissipation substrate 6020 is in contact with the electric control element 60 , and the temperature of the electric control element 60 can be directly transmitted to the heat dissipation substrate 6020 . The fixed baffle 6021 is disposed on the heat dissipation substrate 6020 , so that the fixed baffle 6021 and the heat dissipation substrate 6020 can directly exchange heat. It can be understood that there is no special limitation on the connection method between the fixed baffle 6021 and the heat dissipation substrate 6020. For example, in the example shown in FIG. 3 and FIG. 4, the fixed baffle 6021 is attached to the heat dissipation substrate 6020 . Further, the fixed baffle 6021 is provided with a fixed column (not shown in the figure), and the heat dissipation substrate 6020 is provided with a fixed hole (not shown in the figure), and the fixed column is riveted to the fixed hole. Thus, the contact area between the fixed baffle 6021 and the heat dissipation substrate 6020 can be increased, thereby improving the heat exchange efficiency between the fixed baffle 6021 and the heat dissipation substrate 6020 .
