In multi-split air conditioners, a gas supply line connects the outdoor heat exchanger and the compressor to replenish the compressor's enthalpy. When the expansion valve on the gas supply line is over-adjusted or the sensor feedback is delayed, the injected liquid refrigerant cannot evaporate completely, resulting in a situation where the gaseous refrigerant entering the compressor through the gas supply line contains liquid refrigerant. Excessive liquid refrigerant entering the compressor can cause liquid slugging, resulting in irreparable damage to the compressor. Utility Model Content

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0039] The air conditioning system 10 of this utility model is described below with reference to the accompanying drawings.

[0040] like Figures 1-4 As shown, the air conditioning system 10 of this embodiment includes a refrigerant circuit formed by a compressor 100, a four-way valve 200, an outdoor heat exchanger 300, and an indoor heat exchanger 400 connected in sequence. That is, the compressor 100, the four-way valve 200, the outdoor heat exchanger 300, the throttling device (not shown in the figure), and the indoor heat exchanger 400 are connected in sequence through working fluid pipelines to form a refrigerant circuit.

[0041] In cooling mode, compressor 100 compresses the refrigerant to produce high-temperature, high-pressure gaseous refrigerant. This high-temperature, high-pressure gaseous refrigerant passes through four-way valve 200 and enters outdoor heat exchanger 300 to exchange heat with outdoor air, causing the high-temperature, high-pressure gaseous refrigerant to condense into high-pressure liquid refrigerant. After being throttled by a throttling device, the high-pressure liquid refrigerant enters indoor heat exchanger 400, where it exchanges heat with indoor air and evaporates into low-pressure gaseous refrigerant, thus achieving cooling of the room. The low-pressure gaseous refrigerant then returns to compressor 100 for a refrigerant cycle.

[0042] like Figures 1-4 As shown, the air conditioning system 10 of this utility model embodiment also includes a gas supply pipeline 500 and a heat exchange device 600.

[0043] The gas supply line 500 is connected between the gas supply port 120 of the compressor 100 and the outdoor heat exchanger 300. That is, part of the refrigerant discharged from the refrigerant outlet of the outdoor heat exchanger 300 flows into the indoor heat exchanger 400, and the other part of the refrigerant enters the gas supply port 120 through the gas supply line 500 to supply gas and increase the enthalpy of the compressor 100.

[0044] The heat exchanger 600 has its heat release side inlet 610 connected to the compressor 100's exhaust port 110, and its heat release side outlet 620 connected to the four-way valve 200. A portion of the make-up gas pipeline 500 forms the heat absorption side 630 of the heat exchanger 600. In other words, the refrigerant discharged from the compressor 100's exhaust port 110 first enters the heat exchanger 600 through its heat release side inlet 610, allowing it to exchange heat with the refrigerant in that portion of the make-up gas pipeline 500, thus heating that portion of the refrigerant and enabling it to fully absorb heat and evaporate. After heat exchange, the refrigerant in the heat exchanger 600 flows to the four-way valve 200 through its heat release side outlet 620.

[0045] Compared with related technologies, the air conditioning system 10 of this utility model embodiment includes a refrigerant circuit formed by a compressor 100, a four-way valve 200, an outdoor heat exchanger 300, and an indoor heat exchanger 400 connected in sequence. It also has a gas supply pipe 500 connected between the gas supply port 120 of the compressor 100 and the outdoor heat exchanger 300, and a heat exchange device 600 connected between the exhaust port 110 of the compressor 100 and the four-way valve 200. A portion of the gas supply pipe 500 forms the heat absorption side 630 of the heat exchange device 600. In this embodiment of the invention, the refrigerant in the air supply pipe 500 of the air conditioning system 10 exchanges heat with the refrigerant discharged from the exhaust port 110 of the compressor 100 through the heat exchange device 600, thereby heating the refrigerant in the air supply pipe 500 so that the refrigerant in the air supply pipe 500 can fully evaporate, avoiding the presence of liquid refrigerant in the gaseous refrigerant, and thus ensuring that the refrigerant entering the air supply port 120 of the compressor 100 is completely gaseous. Therefore, the compressor 100 will not have the problem of liquid slugging, and the service life of the compressor 100 is extended.

[0046] like Figures 1-3 As shown, the air conditioning system 10 of this embodiment further includes a plate heat exchanger. A portion of the make-up gas pipeline 500 forms the first heat exchange side of the plate heat exchanger, and a portion of the working fluid pipeline connecting the outdoor heat exchanger 300 and the indoor heat exchanger 400 forms the second heat exchange side of the plate heat exchanger. That is, a portion of the refrigerant discharged from the refrigerant outlet of the outdoor heat exchanger 300 first passes through the second heat exchange side and then flows into the indoor heat exchanger 400. The other portion of the refrigerant enters the make-up gas port 120 through the make-up gas pipeline 500 to make up gas and increase the enthalpy of the compressor 100.

[0047] The heat exchange device 600 of this embodiment includes a housing 660, which defines a heat exchange cavity. A heat-dissipating inlet 610 and a heat-dissipating outlet 620 are formed on the wall of the heat exchange cavity. A portion of a gas supply pipe 500 is disposed in the heat exchange cavity and is made of a thermally conductive material. This allows this portion of the gas supply pipe 500 to exchange heat with the refrigerant in the heat exchange cavity, resulting in not only good heat exchange performance but also a simple structure.

[0048] Furthermore, a portion of the air supply line 500 is coiled, thereby extending the residence time of the refrigerant in the heat exchange chamber in that portion of the air supply line 500, and thus further improving the heat exchange effect.

[0049] In some embodiments, such as Figure 1 and Figure 3 As shown, the air conditioning system 10 of this utility model embodiment also includes an exhaust pipe 700 and a control component.

[0050] An exhaust pipe 700 is connected between the exhaust port 110 and the four-way valve 200, and the exhaust pipe 700 and the heat exchanger 600 are arranged in parallel. The control component is configured to control the exhaust pipe 700 and / or the heat release side inlet 610 to be connected to the exhaust port 110. That is, the control component can control the exhaust pipe 700 to be connected to the exhaust port 110; or, the control component can control the heat release side inlet 610 to be connected to the exhaust port 110; or, the control component can control both the exhaust pipe 700 and the heat release side inlet 610 to be connected to the exhaust port 110.

[0051] When the exhaust port 110 is only connected to the exhaust pipe 700, the refrigerant discharged from the exhaust port 110 of the compressor 100 flows into the four-way valve 200 through the exhaust pipe 700, so that the refrigerant discharged from the compressor 100 does not enter the heat exchange device 600.

[0052] When the exhaust port 110 is only connected to the heat release side inlet 610, the refrigerant discharged from the exhaust port 110 of the compressor 100 flows into the four-way valve 200 only through the heat exchange device 600, so that all the refrigerant discharged from the compressor 100 flows through the heat exchange device 600, improving the heat exchange effect of the heat exchange device 600, thereby making the heating effect of the heat exchange device 600 on the gas supply line 500 better, and ensuring that the compressor 100 will not have the problem of liquid slugging.

[0053] When the exhaust port 110 is fully connected to the heat release side inlet 610 and the exhaust pipe 700, the refrigerant discharged from the compressor 100's exhaust port 110 flows into the four-way valve 200 through the heat exchange device 600 and the exhaust pipe 700. This not only ensures that the heat exchange device 600 heats the make-up gas pipe 500, but also allows the large flow of refrigerant discharged from the compressor 100 to flow smoothly into the four-way valve 200.

[0054] Specifically, such as Figure 3 As shown, the air conditioning system 10 of this embodiment further includes a first pipe 640 and a second pipe 650. The first pipe 640 is connected between the exhaust port 110 and the heat release side inlet 610, that is, one end of the first pipe 640 is connected to the exhaust port 110, and the other end is connected to the heat release side inlet 610 of the heat exchange device 600. The second pipe 650 is connected between the heat release side outlet 620 and the four-way valve 200, that is, one end of the second pipe 650 is connected to the heat release side outlet 620, and the other end is connected to the four-way valve 200.

[0055] The control assembly includes a first switching valve 641 and a second switching valve 701. The first switching valve 641 is disposed on the first pipeline 640, and the second switching valve 701 is disposed on the exhaust pipeline 700. Thus, the first switching valve 641 and the second switching valve 701 are used to control the on / off state of the first pipeline 640 and the exhaust pipeline 700 respectively, resulting in a simple structure and low manufacturing cost.

[0056] In some embodiments, such as Figure 3 As shown, a first expansion valve 642 is installed on the first pipeline 640. The first expansion valve 642 is used to convert the high-temperature and high-pressure refrigerant flowing out of the compressor 100 into a low-temperature and low-pressure mist-like gas-liquid mixture, thereby improving the heat exchange effect of the refrigerant.

[0057] Furthermore, the refrigerant flow rate in the first pipeline 640, the heat exchange device 600, and the second pipeline 650 can be adjusted using the first expansion valve 642.

[0058] Optionally, the first expansion valve 642 can be an electronic expansion valve, so that the first expansion valve 642 has a relatively fast response speed and control accuracy, thereby improving the adjustment speed of the first expansion valve 642.

[0059] In some embodiments, such as Figure 3 As shown, a one-way valve 651 is installed on the second pipe 650; the one-way valve 651 is configured to allow refrigerant to flow from the first pipe 640 to the second pipe 650. This ensures that the refrigerant can flow sequentially through the first pipe 640, the heat exchanger 600, and the second pipe 650, preventing the refrigerant in the exhaust pipe 700 from flowing back through the path formed by the first pipe 640, the heat exchanger 600, and the second pipe 650.

[0060] In some embodiments, such as Figure 3As shown, a second expansion valve 501 is installed on the gas supply line 500, and the heat absorption side 630 of the heat exchange device 600 is located between the second expansion valve 501 and the gas supply port 120 of the compressor 100. That is, a portion of the heat absorption side 630 of the heat exchange device 600 is located between the second expansion valve 501 and the gas supply port 120 of the compressor 100 on the gas supply line 500, thereby allowing the heat exchange device 600 to heat the refrigerant sprayed through the second expansion valve 501, thus ensuring that the refrigerant sprayed through the second expansion valve 501 is completely gaseous.

[0061] In some embodiments, such as Figure 3 As shown, the air conditioning system 10 of this utility model embodiment also includes a first detection component and a second detection component.

[0062] The first detection component includes a first temperature sensor 510 and a first pressure sensor 520. Both the first temperature sensor 510 and the first pressure sensor 520 are disposed on the portion of the air supply line 500 located between the outdoor heat exchanger 300 and the second expansion valve 501. The second detection component includes a second temperature sensor 530 and a second pressure sensor 540. Both the second temperature sensor 530 and the second pressure sensor 540 are disposed on the portion of the air supply line 500 located between the exhaust port 110 and the second expansion valve 501.

[0063] In other words, the temperature and pressure of the refrigerant in the gas supply line 500 before entering the second expansion valve 501 are detected by the first temperature sensor 510 and the first pressure sensor 520, thereby detecting the superheat of the refrigerant before entering the second expansion valve 501. The temperature and pressure of the refrigerant discharged from the second expansion valve 501 are detected by the second temperature sensor 530 and the second pressure sensor 540, thereby detecting the superheat of the refrigerant after being discharged from the second expansion valve 501. Therefore, the state of the refrigerant is detected by the first detection component and the second detection component.

[0064] It is understandable that when the refrigerant temperature is below the saturation temperature corresponding to the current pressure, the refrigerant is completely liquid. When the refrigerant temperature is above the saturation temperature corresponding to the current pressure, the refrigerant is completely gaseous.

[0065] When the first detection component detects that the refrigerant is completely in a gaseous state, it controls the first switching valve 641 to close and the second switching valve 701 to open, so as to adjust the state of the refrigerant by controlling only the opening degree of the second expansion valve 501.

[0066] When the first detection component detects that the refrigerant is in a mixed liquid and gaseous state or in a liquid state, and the second detection component detects that the refrigerant is entirely in a gaseous state, both the first switching valve 641 and the second switching valve 701 are opened. This allows the heat exchange device 600 to heat the refrigerant in the make-up gas pipeline 500, ensuring that the refrigerant entering the compressor 100 is entirely in a gaseous state. The refrigerant entering the heat exchange device 600 is adjusted via the first expansion valve 642.

[0067] When the first detection component detects that the refrigerant is in a liquid and gaseous state or that the refrigerant is liquid, and the second detection component detects that the refrigerant is in a liquid and gaseous state or that the refrigerant is liquid, the first switching valve 641 is opened and the second switching valve 701 is closed, so that the heat exchange device 600 heats the refrigerant in the gas supply line 500 to ensure that the refrigerant entering the compressor 100 is completely gaseous.

[0068] The air conditioner 20 of this utility model is described below with reference to the accompanying drawings.

[0069] like Figure 4 As shown, the air conditioner 20 of this utility model embodiment includes the air conditioning system 10 of any of the above embodiments.

[0070] The air conditioner 20 of this embodiment includes an air conditioning system 10 comprising a refrigerant circuit formed by a compressor 100, a four-way valve 200, an outdoor heat exchanger 300, and an indoor heat exchanger 400 connected in sequence. It also includes a gas supply pipe 500 connected between the gas supply port 120 of the compressor 100 and the outdoor heat exchanger 300, and a heat exchange device 600 connected between the exhaust port 110 of the compressor 100 and the four-way valve 200. A portion of the gas supply pipe 500 forms the heat absorption side 630 of the heat exchange device 600. In this embodiment of the invention, the refrigerant in the air supply pipe 500 of the air conditioning system 10 exchanges heat with the refrigerant discharged from the exhaust port 110 of the compressor 100 through the heat exchange device 600, thereby heating the refrigerant in the air supply pipe 500 so that the refrigerant in the air supply pipe 500 can fully evaporate, avoiding the presence of liquid refrigerant in the gaseous refrigerant, and thus ensuring that the refrigerant entering the air supply port 120 of the compressor 100 is completely gaseous. Therefore, the compressor 100 will not have the problem of liquid slugging, and the service life of the compressor 100 is extended.

[0071] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention.
