Description

Technical Field

[0001] This application relates to the technical field of air conditioning, and more particularly to an air conditioning device. Background Technology

[0002] An air conditioning unit is a device used to regulate indoor air temperature, humidity, and air quality. Air conditioning units achieve environmental regulation through a refrigeration cycle, heating elements, and a ventilation system.

[0003] In related technologies, air conditioning devices include compressors, four-way valves, indoor heat exchangers, indoor fans, throttling devices, and outdoor heat exchangers. When operating under low temperature and high humidity conditions for heating, the outdoor heat exchanger is prone to frosting and requires regular defrosting.

[0004] During the defrosting process, the four-way valve of the air conditioner will switch from heating mode to cooling mode, which will prevent heat from being delivered to the room and affect the user experience. Summary of the Invention

[0005] This application provides an air conditioning device that can continuously supply heat to the room during defrosting.

[0006] This application provides an air conditioning device, comprising:

[0007] compressor;

[0008] The first four-way valve, the D port of the first four-way valve is connected to the exhaust port of the compressor;

[0009] The second four-way valve has its M port connected to the compressor's exhaust port via the first pipeline, and its N port connected to the compressor's suction port via the second pipeline.

[0010] The indoor heat exchange component is connected to the E port of the first four-way valve;

[0011] The first outdoor heat exchange component includes a third pipeline. One end of the third pipeline is connected to the P port of the second four-way valve, and the other end is connected to the indoor heat exchange component. The first outdoor heat exchanger is installed on the third pipeline.

[0012] The second outdoor heat exchange component is connected in parallel with the first outdoor heat exchange component. The second outdoor heat exchange component includes a fourth pipeline. The two ends of the fourth pipeline are respectively connected to the Q interface of the second four-way valve and the indoor heat exchange component. The second outdoor heat exchanger is installed on the fourth pipeline.

[0013] When the first outdoor heat exchanger defrosts, the M and P ports of the second four-way valve are connected, the Q and N ports of the second four-way valve are connected, and the D and E ports of the first four-way valve are connected.

[0014] When the second outdoor heat exchanger defrosts, the M and Q ports of the second four-way valve are connected, the P and N ports of the second four-way valve are connected, and the D and E ports of the first four-way valve are connected.

[0015] In this way, when defrosting is needed, a rotating defrosting mode can be adopted. When the first outdoor heat exchanger is defrosting, the second outdoor heat exchanger continues to heat the room. Conversely, when the second outdoor heat exchanger is defrosting, the first outdoor heat exchanger continues to heat the room. This ensures continuous heating indoors and improves the user experience.

[0016] In some embodiments, a first control valve is disposed in a first pipeline, and the first control valve is connected to the discharge port of the compressor and the M interface of the second four-way valve respectively. The first control valve is configured to control the compressor to be connected to or not connected to the M interface of the second four-way valve.

[0017] The second control valve is installed in the second pipeline. The second control valve is connected to the N port of the second four-way valve and the suction port of the compressor. The second control valve controls whether the N port of the second four-way valve and the suction port of the compressor are connected or not connected.

[0018] One end of the fifth pipeline is connected to the P port of the first outdoor heat exchange component and the second four-way valve, and the other end is connected to the Q port of the second outdoor heat exchange component and the second four-way valve. The third control valve is located in the fifth pipeline and is configured to control the connection or disconnection of the first outdoor heat exchange component and the second outdoor heat exchange component.

[0019] The sixth pipeline is connected at one end to the C port of the first four-way valve and at the other end to the first pipeline. The fourth control valve is installed on the sixth pipeline and is configured to control the connection or disconnection between the C port of the first four-way valve and the M port of the second four-way valve.

[0020] The S-port of the first four-way valve is connected to the second pipeline.

[0021] In this way, by setting up a first control valve, a second control valve, a third control valve, a second pipeline, a fourth control valve, a fifth pipeline, and a third control valve, it is beneficial to realize that the first outdoor heat exchanger and the second outdoor heat exchanger can simultaneously cool or heat, or one of the first outdoor heat exchanger and the second outdoor heat exchanger can heat while the other does not operate, or one of the first outdoor heat exchanger and the second outdoor heat exchanger can cool while the other does not operate.

[0022] In some embodiments, the indoor heat exchange assembly includes an indoor heat exchanger and a first expansion valve connected in series; the E port of the first four-way valve is connected, and the first expansion valve is connected to the first outdoor heat exchange assembly and the second outdoor heat exchange assembly respectively.

[0023] In this way, the first expansion valve can control the refrigerant flow rate and reduce the refrigerant pressure. The refrigerant in the indoor heat exchanger exchanges heat with the indoor air.

[0024] In some embodiments, the first outdoor heat exchange assembly includes a first outdoor heat exchanger and a second expansion valve connected in series, the first outdoor heat exchanger being connected to a second four-way valve, and the second expansion valve being connected to the first expansion valve.

[0025] The second outdoor heat exchange assembly includes a second outdoor heat exchanger and a third expansion valve connected in series. The second outdoor heat exchanger is connected to a second four-way valve, and the third expansion valve is connected to a first expansion valve.

[0026] In this way, the second expansion valve and the first expansion valve can work together to achieve two-stage throttling. The third expansion valve and the first expansion valve can work together to achieve two-stage throttling.

[0027] In some embodiments, including:

[0028] The first temperature sensing element is configured to detect a first temperature, which is the temperature of the first outdoor heat exchanger.

[0029] The second temperature sensing element is configured to detect a second temperature, which is the temperature of the second outdoor heat exchanger.

[0030] The third temperature sensor is configured to detect a third temperature, which is the outdoor ambient temperature.

[0031] The first pressure sensing element is configured to detect the compressor's suction pressure;

[0032] The controller, the first temperature sensor, the second temperature sensor, the third temperature sensor, and the first pressure sensor are all electrically connected to the controller; the controller is configured as follows:

[0033] Obtain the first temperature, second temperature, third temperature, and inhalation pressure;

[0034] The target defrost temperature is obtained based on the third temperature.

[0035] If at least one of the first temperature and the second temperature is less than the target defrost temperature, and the suction pressure is less than the target defrost pressure, and the air conditioning device has been continuously heating for a first preset time, the air conditioning device is controlled to enter the alternating defrost mode.

[0036] If either the first temperature or the second temperature is greater than the target defrost temperature, or the suction pressure is greater than the target defrost pressure, and this condition is maintained for a second preset time, the alternating defrost mode will end.

[0037] In this way, the automatic start and stop of the alternating defrosting mode can be achieved through the control of the controller.

[0038] In some embodiments, the controller is configured to:

[0039] When switching defrosting modes, compare the values ​​of the first and second temperatures;

[0040] If the first temperature is greater than the second temperature, the air conditioning unit is controlled to use the second outdoor heat exchanger as the one to be defrosted.

[0041] If the first temperature is not greater than the second temperature, the air conditioning device is controlled to use the first outdoor heat exchanger as the one to be defrosted.

[0042] In this way, the outdoor heat exchanger that needs to be defrosted can be selected through the controller.

[0043] In some embodiments, including:

[0044] The second pressure sensing element is configured to detect the compressor's discharge pressure;

[0045] The fourth temperature sensor is configured to detect a fourth temperature, which is the temperature of the indoor heat exchanger; the second pressure sensor, the fourth temperature sensor, the first expansion valve, the second expansion valve, and the third expansion valve are all electrically connected to the controller, which is configured to:

[0046] When switching defrosting modes, the temperature, fourth temperature, and exhaust pressure of the device to be defrosted are obtained; where the temperature of the device to be defrosted is either the first temperature or the second temperature.

[0047] The outdoor supercooling is obtained by subtracting the temperature of the object to be defrosted from the saturation temperature corresponding to the exhaust pressure.

[0048] The indoor subcooling is obtained by subtracting the fourth temperature from the saturation temperature corresponding to the exhaust pressure.

[0049] By controlling the opening degree of at least one of the first expansion valve, the second expansion valve, and the third expansion valve, the value of the outdoor subcooling minus the indoor subcooling is made negative.

[0050] In this way, by adjusting the opening of the electronic expansion valve and using the subcooling as a reference, the amount of refrigerant passing through the outdoor heat exchanger and the indoor heat exchanger to be defrosted is controlled. The purpose is to ensure that there is enough refrigerant in the indoor heat exchanger to meet the user's thermal comfort.

[0051] In some embodiments, the target defrost temperature is:

[0052] T eo =b+k×T a

[0053] Where k and b are correction coefficients, and Ta is the third temperature.

[0054] This allows for the calculation of the target defrost temperature and target defrost pressure.

[0055] In some embodiments, when the air conditioning unit is cooling, the first outdoor heat exchange component and the second outdoor heat exchange component operate simultaneously, or one of the first outdoor heat exchange component and the second outdoor heat exchange component operates.

[0056] In this way, the area of ​​the heat exchanger can be controlled and adjusted by working one of the first outdoor heat exchange components and the second outdoor heat exchange components, or by working both of them simultaneously.

[0057] In some embodiments, when the air conditioning device is heating, the first outdoor heat exchange component and the second outdoor heat exchange component operate simultaneously, or one of the first outdoor heat exchange component and the second outdoor heat exchange component operates.

[0058] In this way, the area of ​​the heat exchanger can be controlled and adjusted by working one of the first outdoor heat exchange components and the second outdoor heat exchange components, or by working both of them simultaneously. Attached Figure Description

[0092] To make the objectives and implementation methods of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the exemplary embodiments described are only some embodiments of this application, and not all embodiments.

[0093] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0094] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0095] The terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0096] When an air conditioner is operating in heating mode under low temperature and high humidity conditions, the outdoor heat exchanger is prone to frost buildup. As the amount of frost increases, the heat transfer coefficient of the outdoor heat exchanger decreases, and the airflow resistance increases, severely affecting heating performance. Therefore, periodic forced or manual defrosting is necessary. However, during the defrosting process, the four-way valve switches from heating mode to cooling mode, and the indoor fan stops running, preventing heat from being delivered to the room and impacting the user experience.

[0097] Furthermore, the air conditioning industry often designs indoor and outdoor heat exchanger areas based on nominal cooling and heating conditions, combining variable frequency compressor frequency adjustment, electronic expansion valve opening adjustment, and fan speed adjustment to meet load requirements, with the heat exchanger area remaining constant throughout operation. However, for partial loads or extreme conditions, relying solely on the control actions of the actuators cannot meet the basic reliability requirements or high energy efficiency requirements of the system. Therefore, it is necessary to control and adjust the heat exchanger area when necessary.

[0098] To address the aforementioned technical problems, this application provides an air conditioning device, comprising a compressor, a first four-way valve, a second four-way valve, an indoor heat exchange component, a first outdoor heat exchange component, and a second outdoor heat exchange component. When defrosting is required, a rotating defrosting mode can be adopted. When the first outdoor heat exchange component is defrosting, the second outdoor heat exchange component continuously heats the room. Conversely, when the second outdoor heat exchange component is defrosting, the first outdoor heat exchange component continuously heats the room. This ensures continuous heating indoors and improves the user experience.

[0099] Furthermore, the area of ​​the heat exchanger can be controlled and adjusted by operating one of the first outdoor heat exchange components and the second outdoor heat exchange components, or by operating both simultaneously.

[0100] Figure 1 This is a schematic diagram of the structure of an air conditioning device provided in an embodiment of this application.

[0101] See Figure 1 As shown, this application provides an air conditioning device, including a compressor 100. The compressor 100 is used to compress a low-pressure gaseous refrigerant into a high-pressure, high-temperature gaseous refrigerant.

[0102] In some embodiments, the air conditioning device includes a first four-way valve 200. The first four-way valve 200 is used to change the flow direction of the refrigerant.

[0103] The first four-way valve 200 includes a D port, a C port, an S port, and an E port. When power is off, the D port is connected to the C port, and the S port is connected to the E port. When power is on, the D port is connected to the E port, and the S port is connected to the C port.

[0104] The D port of the first four-way valve 200 is connected to the exhaust port of the compressor 100.

[0105] In some embodiments, the air conditioning unit includes a second four-way valve 300. The second four-way valve 300 is used to change the flow direction of the refrigerant.

[0106] The second four-way valve 300 includes an M port, a P port, an N port, and a Q port. When power is off, the M port is connected to the P port, and the N port is connected to the Q port. When power is on, the M port is connected to the Q port, and the N port is connected to the P port.

[0107] The M port of the second four-way valve 300 is connected to the exhaust port of the compressor 100 through the first pipeline 700, and the N port of the second four-way valve 300 is connected to the intake port of the compressor 100 through the second pipeline 800.

[0108] In some embodiments, the air conditioning device includes an indoor heat exchange assembly 400. The indoor heat exchange assembly 400 is used to exchange heat with indoor air.

[0109] The indoor heat exchange component 400 is connected to the E interface of the first four-way valve 200.

[0110] In some embodiments, the air conditioning device includes a first outdoor heat exchange component 500.

[0111] The first outdoor heat exchange component 500 includes a third pipe 510, one end of which is connected to the P port of the second four-way valve 300, and the other end is connected to the indoor heat exchange component 400. The first outdoor heat exchanger 520 is installed on the third pipe 510.

[0112] In some embodiments, the air conditioning device includes a second outdoor heat exchange component 600.

[0113] The second outdoor heat exchange component 600 is connected in parallel with the first outdoor heat exchange component 500. The second outdoor heat exchange component 600 includes a fourth pipe 610. The two ends of the fourth pipe 610 are connected to the Q interface of the second four-way valve 300 and the indoor heat exchange component 400, respectively. The second outdoor heat exchanger 620 is installed on the fourth pipe 610.

[0114] Figure 2 This is a schematic diagram of the first state of the alternating defrosting mode of the air conditioning device provided in the embodiments of this application. Figure 3 This is a schematic diagram of the second state of the alternating defrosting mode of the air conditioning device provided in the embodiments of this application.

[0115] See Figure 2 As shown, when the first outdoor heat exchanger 520 defrosts, the M and P ports of the second four-way valve 300 are connected, the Q and N ports of the second four-way valve 300 are connected, and the D and E ports of the first four-way valve 200 are connected.

[0116] The refrigerant flowing out of compressor 100 is divided into two paths. One path flows through the D and E ports of the first four-way valve 200 to the indoor heat exchanger 400, and then through the second outdoor heat exchanger 620, the Q and N ports of the second four-way valve 300, and finally back into compressor 100. The other path flows through the M and P ports of the second four-way valve 300 to the first outdoor heat exchanger 520, and then through the second outdoor heat exchanger 620, the Q and N ports of the second four-way valve 300, and finally back into compressor 100.

[0117] See Figure 3 As shown, when the second outdoor heat exchanger 620 defrosts, the M and Q ports of the second four-way valve 300 are connected, the P and N ports of the second four-way valve 300 are connected, and the D and E ports of the first four-way valve 200 are connected.

[0118] The refrigerant flowing out of compressor 100 is divided into two paths. One path flows through the D and E ports of the first four-way valve 200 to the indoor heat exchange component 400, and then through the first outdoor heat exchanger 520 and the P and N ports of the second four-way valve 300 to compressor 100. The other path flows through the M and Q ports of the second four-way valve 300 to the second outdoor heat exchanger 620, and then through the first outdoor heat exchanger 520 and the P and N ports of the second four-way valve 300 to compressor 100.

[0119] Understandably, when defrosting is required, a rotating defrosting mode can be adopted. While the first outdoor heat exchanger 500 is defrosting, the second outdoor heat exchanger 600 continues to heat the room. Conversely, while the second outdoor heat exchanger 600 is defrosting, the first outdoor heat exchanger 500 continues to heat the room. This ensures continuous heating indoors and improves the user experience.

[0120] See Figure 1 As shown, in some embodiments, a first control valve 710 is provided in the first pipeline 700.

[0121] The first control valve 710 is connected to the exhaust port of the compressor 100 and the M interface of the second four-way valve 300, respectively. The first control valve 710 is configured to control whether the compressor 100 is connected to or not connected to the M interface of the second four-way valve 300.

[0122] In some embodiments, a second control valve 810 is disposed in a second pipeline 800. The second control valve 810 is connected to the N port of the second four-way valve 300 and the suction port of the compressor 100, respectively. The second control valve 810 controls whether the N port of the second four-way valve 300 and the suction port of the compressor 100 are connected or not connected.

[0123] One end of the fifth pipeline 1000 is connected to the P port of the first outdoor heat exchange component 500 and the second four-way valve 300, respectively, and the other end is connected to the Q port of the second outdoor heat exchange component 600 and the second four-way valve 300, respectively. The third control valve 1110 is located in the fifth pipeline 1000 and is configured to control the connection or disconnection of the first outdoor heat exchange component 500 and the second outdoor heat exchange component 600.

[0124] In some embodiments, the air conditioning device includes a sixth conduit 900. One end of the sixth conduit 900 is connected to the C port of the first four-way valve 200, and the other end of the sixth conduit 900 is connected to the first conduit 700. A fourth control valve 910 is disposed on the sixth conduit 900 and is configured to control whether the C port of the first four-way valve 200 and the M port of the second four-way valve 300 are connected or not connected.

[0125] The S-port of the first four-way valve 200 is connected to the second pipeline 800.

[0126] It should be noted that by setting the first control valve 710, the second control valve 810, the third control valve 1110, the second pipeline 800, the fourth control valve 910, the fifth pipeline 1000, and the third control valve 1110, it is beneficial to realize that the first outdoor heat exchanger 520 and the second outdoor heat exchanger 620 can simultaneously cool or heat, or one of the first outdoor heat exchanger 520 and the second outdoor heat exchanger 620 can heat while the other does not operate, or one of the first outdoor heat exchanger 520 and the second outdoor heat exchanger 620 can cool while the other does not operate.

[0127] In some embodiments, the indoor heat exchange assembly 400 includes an indoor heat exchanger 410 and a first expansion valve 420 connected in series.

[0128] The first four-way valve 200 is connected to its E port, and the first expansion valve 420 is connected to both the first outdoor heat exchange component 500 and the second outdoor heat exchange component 600. The first expansion valve 420 is used to control the flow rate of the refrigerant and reduce its pressure. The first expansion valve 420 can be an electronic expansion valve.

[0129] In some embodiments, the first outdoor heat exchange assembly 500 includes a first outdoor heat exchanger 520 and a second expansion valve 530 connected in series.

[0130] The first outdoor heat exchanger 520 is connected to the second four-way valve 300, and the second expansion valve 530 is connected to the first expansion valve 420.

[0131] The second expansion valve 530 is used to control the flow rate of the refrigerant and reduce its pressure. The second expansion valve 530 can be an electronic expansion valve. Thus, the second expansion valve 530, in conjunction with the first expansion valve 420, can achieve two-stage throttling.

[0132] In some embodiments, the second outdoor heat exchange assembly 600 includes a second outdoor heat exchanger 620 and a third expansion valve 630 connected in series. The second outdoor heat exchanger 620 is connected to a second four-way valve 300, and the third expansion valve 630 is connected to a first expansion valve 420.

[0133] The third expansion valve 630 is used to control the flow rate of the refrigerant and reduce its pressure. The third expansion valve 630 can be an electronic expansion valve. Thus, the third expansion valve 630, in conjunction with the first expansion valve 420, can achieve two-stage throttling.

[0134] Figure 4 This is a schematic diagram of the first state of the heating mode of the air conditioning device provided in the embodiments of this application.

[0135] See Figure 4 As shown, the first four-way valve 200 is energized, the second four-way valve 300 is de-energized, the first control valve 710 is disconnected, the third control valve 1110 is disconnected, the fourth control valve 910 is opened, and the second control valve 810 is opened. The high-temperature and high-pressure refrigerant discharged from the compressor 100 flows into the indoor heat exchanger 410 through the D and E ports of the first four-way valve 200. The high-pressure and medium-temperature refrigerant formed by condensation flows into the first expansion valve 420, and then splits into two paths. One path, after being throttled by the second expansion valve 530, is a low-temperature and low-pressure liquid refrigerant that flows into the first outdoor heat exchanger 520. The low-pressure and low-temperature gaseous refrigerant formed by evaporation returns to the compressor 100 through the P and M ports of the second four-way valve 300 and the C and S ports of the first four-way valve 200. After being throttled by the third expansion valve 630, the low-temperature, low-pressure liquid refrigerant flows into the second outdoor heat exchanger 620. The low-pressure, low-temperature gaseous refrigerant formed by evaporation returns to the compressor 100 through the N and Q ports of the second four-way valve 300.

[0136] Figure 5 This is a schematic diagram of the second state of the heating mode of the air conditioning device provided in the embodiments of this application.

[0137] See Figure 5As shown, the first four-way valve 200 is energized, the second four-way valve 300 is de-energized, the first control valve 710 is disconnected, the fourth control valve 910 is disconnected, the second control valve 810 is opened, and the third control valve 1110 is opened. The high-temperature, high-pressure refrigerant discharged from the compressor 100 flows into the indoor heat exchanger 410 through the D and E ports of the first four-way valve 200. The high-pressure, medium-temperature refrigerant formed by condensation flows into the first expansion valve 420. It then splits into two paths: one path, after being throttled by the second expansion valve 530, flows into the first outdoor heat exchanger 520 as a low-temperature, low-pressure liquid refrigerant; the other path, after being throttled by the third expansion valve 630, flows into the second outdoor heat exchanger 620 as a low-temperature, low-pressure liquid refrigerant. The low-pressure, low-temperature gaseous refrigerant formed by evaporation from both flows merges and returns to the compressor 100 through the Q and N ports of the second four-way valve 300.

[0138] Figure 6 This is a schematic diagram of the cooling mode of the air conditioning device provided in the embodiments of this application.

[0139] See Figure 6 As shown, the first four-way valve 200 is de-energized, the second four-way valve 300 is energized, at least one of the first control valve 710 and the fourth control valve 910 is open, the second control valve 810 is disconnected, and the third control valve 1110 is open. The high-temperature and high-pressure refrigerant discharged from the compressor 100 flows into the first four-way valve 200 through its D and C ports, and the second four-way valve 300 through its M and Q ports, and is then divided into two paths. One path flows through the first outdoor heat exchanger 520 and the second expansion valve 530, and the other path flows through the second outdoor heat exchanger 620 and the third expansion valve 630. The high-pressure and medium-temperature refrigerant formed by condensation merges and is then throttled by the first expansion valve 420. The low-temperature and low-pressure liquid refrigerant flows into the indoor heat exchanger 410, and the low-pressure and low-temperature gaseous refrigerant formed by evaporation returns to the compressor 100 through the first four-way valve 200's E and S ports.

[0140] Figure 7 This is a schematic diagram of the reverse defrosting mode of the air conditioning device provided in the embodiments of this application.

[0141] See Figure 7As shown, the first four-way valve 200 and the second four-way valve 300 are de-energized. At least one of the first control valve 710 and the fourth control valve 910 is open. The second control valve 810 is disconnected, and the third control valve 1110 is open. The high-temperature and high-pressure refrigerant discharged from the compressor 100 flows into the outdoor side through the D and C ports of the first four-way valve 200 and the M and P ports of the second four-way valve 300. It then splits into two paths: one through the first outdoor heat exchanger 520 and the second expansion valve 530, and the other through the second outdoor heat exchanger 620 and the third expansion valve 630. The high-pressure, low-temperature refrigerant formed after defrosting merges and is throttled by the first expansion valve 420. The low-temperature, low-pressure liquid refrigerant flows into the indoor heat exchanger 410, and the low-pressure, low-temperature gaseous refrigerant formed by evaporation returns to the compressor 100 through the E and S ports of the first four-way valve 200. It should be noted that the indoor fan is turned off or runs at a low speed during the defrosting process.

[0142] It should be noted that this operating mode can also be used for cooling. Moreover, compared with the normal heating mode, only the first four-way valve 200 needs to be switched.

Figure 9 This is a schematic diagram of the second state of the variable area heating mode of the air conditioning device provided in the embodiments of this application.

[0144] See Figure 8 and Figure 9 As shown, in some embodiments, when the air conditioning device is heating, the first outdoor heat exchange component 500 and the second outdoor heat exchange component 600 operate simultaneously, or one of the first outdoor heat exchange component 500 and the second outdoor heat exchange component 600 operates.

[0145] See Figure 8 As shown, when the first outdoor heat exchanger 520 is operated as a non-operating component, the first four-way valve 200 is energized, the second four-way valve 300 is de-energized, the first control valve 710 is disconnected, the fourth control valve 910 is disconnected, the second control valve 810 is opened, and the third control valve 1110 is disconnected. The high-temperature, high-pressure refrigerant discharged from the compressor 100 flows into the indoor heat exchanger 410 and the first expansion valve 420 through the D and E ports of the first four-way valve 200. It condenses and releases heat indoors to form a high-pressure, medium-temperature liquid refrigerant. This liquid refrigerant is then throttled by the third expansion valve 630 and flows into the second outdoor heat exchanger 620. The low-pressure, low-temperature gaseous refrigerant formed by evaporation returns to the compressor 100 through the Q and N ports of the second four-way valve 300.

[0146] It should be noted that, to effectively prevent refrigerant buildup in the first outdoor heat exchanger 520, the second expansion valve 530 is fully closed. When the system high pressure exceeds the limit, the opening of the second expansion valve 530 should be appropriately increased.

[0147] See Figure 9 As shown, when the second outdoor heat exchanger 620 is operated as a non-operating component, the first four-way valve 200 is energized, the second four-way valve 300 is de-energized, the first control valve 710 is disconnected, the fourth control valve 910 is opened, the second control valve 810 is disconnected, and the third control valve 1110 is disconnected. The high-temperature, high-pressure refrigerant discharged from the compressor 100 flows into the indoor heat exchanger 410 and the electronic expansion valve through the D and E ports of the first four-way valve 200. It condenses and releases heat indoors to form a high-pressure, medium-temperature liquid refrigerant. This liquid refrigerant is then throttled by the second expansion valve 530, and flows into the first outdoor heat exchanger 520. The low-pressure, low-temperature gaseous refrigerant formed by evaporation returns to the compressor 100 through the P and M ports of the second four-way valve 300.

[0148] It should be noted that, to effectively prevent refrigerant buildup in the second outdoor heat exchanger 620, the third expansion valve 630 is fully closed. When the system high pressure exceeds the limit, the opening of the third expansion valve 630 should be appropriately increased.

Figure 11 This is a schematic diagram of the second state of the variable area cooling mode of the air conditioning device provided in the embodiments of this application.

[0151] See Figure 10 As shown, when the first outdoor heat exchanger 520 is operated as a non-operating component, the first four-way valve 200 is de-energized, the second four-way valve 300 is energized, at least one of the first control valve 710 and the fourth control valve 910 is open, the second control valve 810 is closed, and the third control valve 1110 is closed. The high-temperature and high-pressure refrigerant discharged from the compressor 100 flows into the second outdoor heat exchanger 620 and the third expansion valve 630 through the M and Q ports of the second four-way valve 300. After condensation and heat release, it forms a high-pressure, medium-temperature liquid refrigerant. After being throttled by the first expansion valve 420, the low-temperature, low-pressure liquid refrigerant flows into the indoor heat exchanger 410. After evaporation, the low-pressure, low-temperature gaseous refrigerant returns to the compressor 100 through the E and S ports of the first four-way valve 200.

[0152] It should be noted that, to effectively prevent refrigerant buildup in the first outdoor heat exchanger 520, the second expansion valve 530 is fully closed. When the system high pressure exceeds the limit, the opening of the second expansion valve 530 should be appropriately increased.

[0153] See Figure 11 As shown, when the second outdoor heat exchanger 620 is operated as a non-operating component, the first four-way valve 200 and the second four-way valve 300 are de-energized, at least one of the first control valve 710 and the fourth control valve 910 is open, the second control valve 810 is closed, and the third control valve 1110 is closed. The high-temperature and high-pressure refrigerant discharged from the compressor 100 flows into the first outdoor heat exchanger 520 and the second expansion valve 530 through the M and P ports of the second four-way valve 300. After condensation and heat release, it forms a high-pressure, medium-temperature liquid refrigerant. After being throttled by the first expansion valve 420, the low-temperature, low-pressure liquid refrigerant flows into the indoor heat exchanger 410. After evaporation, the low-pressure, low-temperature gaseous refrigerant returns to the compressor 100 through the E and S ports of the first four-way valve 200.

[0154] It should be noted that, to effectively prevent refrigerant buildup in the second outdoor heat exchanger 620, the third expansion valve 630 is fully closed. When the system high pressure exceeds the limit, the opening of the third expansion valve 630 should be appropriately increased.

[0155] Figure 12 This is a control principle diagram of an air conditioning device provided in an embodiment of this application.

[0156] See Figure 12 As shown, in some embodiments, the air conditioning device includes a first temperature sensing element 1100.

[0157] The first temperature sensing element 1100 is configured to detect a first temperature, which is the temperature of the first outdoor heat exchanger 520. Specifically, the first temperature sensing element 1100 can contact the wall surface of the first outdoor heat exchanger 520.

[0158] The first temperature detection element 1100 can be a temperature sensor.

[0159] In some embodiments, the air conditioning device includes a second temperature sensing element 1200.

[0160] The second temperature sensing element 1200 is configured to detect a second temperature, which is the temperature of the second outdoor heat exchanger 620. Specifically, the second temperature sensing element 1200 can contact the wall surface of the second outdoor heat exchanger 620.

[0161] The second temperature detection element 1200 can be a temperature sensor.

[0162] In some embodiments, the air conditioning device includes a third temperature sensor 1300.

[0163] The third temperature sensor 1300 is configured to detect a third temperature, which is the outdoor ambient temperature.

[0164] The third temperature detection element 1300 can be a temperature sensor.

[0165] In some embodiments, the air conditioning device includes a first pressure sensing element 1400.

[0166] The first pressure sensing element 1400 is configured to detect the suction pressure of the compressor 100.

[0167] The first pressure detection element 1400 can be a pressure sensor.

[0168] In some embodiments, the air conditioning device includes a controller 1500.

[0169] The first temperature sensor 1100, the second temperature sensor 1200, the third temperature sensor 1300 and the first pressure sensor 1400 are all electrically connected to the controller 1500.

[0170] In some embodiments, the controller 1500 is configured to:

[0171] Obtain the first temperature, second temperature, third temperature, and inhalation pressure.

[0172] The target defrost temperature and target defrost pressure are obtained based on the third temperature.

[0173] If at least one of the first temperature and the second temperature is less than the target defrost temperature, and the suction pressure is less than the target defrost pressure, and the air conditioning device has been continuously heating for a first preset time, the air conditioning device is controlled to enter the alternating defrost mode.

[0174] If either the first temperature or the second temperature is greater than the target defrost temperature, or the suction pressure is greater than the target defrost pressure, and this condition is maintained for a second preset time, the alternating defrost mode will end.

[0175] In this way, the automatic start and end of the alternating defrosting mode can be achieved through the control of the controller 1500.

[0176] For example, the first preset time can be 15 minutes. The second preset time can be 30 seconds.

[0177] In some embodiments, the controller 1500 is configured to:

[0178] When switching defrosting modes, compare the values ​​of the first and second temperatures.

[0179] If the first temperature is greater than the second temperature, the air conditioning device is controlled to use the second outdoor heat exchanger 620 as the one to be defrosted.

[0180] If the first temperature is not greater than the second temperature, the air conditioning device is controlled to use the first outdoor heat exchanger 520 as the one to be defrosted.

[0181] In this way, the outdoor heat exchanger that needs to be defrosted can be selected via the controller 1500.

[0182] In some embodiments, the air conditioning device includes a second pressure sensing element 1600.

[0183] The second pressure sensing element 1600 is configured to detect the discharge pressure of the compressor 100.

[0184] The second pressure detection element 1600 can be a pressure sensor.

[0185] In some embodiments, the air conditioning device includes a fourth temperature sensor 1700.

[0186] The fourth temperature sensor 1700 is configured to detect a fourth temperature, which is the temperature of the indoor heat exchanger 410. Specifically, the fourth temperature sensor 1700 can contact the wall surface of the indoor heat exchanger 410.

[0187] The second pressure sensor 1600, the fourth temperature sensor 1700, the first expansion valve 420, the second expansion valve 530, and the third expansion valve 630 are all electrically connected to the controller 1500. The controller 1500 is configured as follows:

[0188] When switching defrosting modes, obtain the temperature, fourth temperature, and exhaust pressure of the device to be defrosted.

[0189] Among them, the temperature of the person to be defrosted is either the first temperature or the second temperature;

[0190] The outdoor supercooling is obtained by subtracting the temperature of the object to be defrosted from the saturation temperature corresponding to the exhaust pressure.

[0191] The indoor subcooling is obtained by subtracting the fourth temperature from the saturation temperature corresponding to the exhaust pressure.

[0192] By controlling the opening degree of at least one of the first expansion valve 420, the second expansion valve 530, and the third expansion valve 630, the value of the outdoor subcooling minus the indoor subcooling is made negative.

[0193] In this way, by adjusting the opening of the electronic expansion valve and taking the subcooling as a reference, the amount of refrigerant passing through the outdoor heat exchanger and indoor heat exchanger 410 to be defrosted is controlled. The purpose is to ensure that there is enough refrigerant in the indoor heat exchanger 410 to meet the user's thermal comfort.

[0194] It should be noted that the specific negative value of the difference between the outdoor subcooling and the indoor subcooling can be determined during development and debugging.

[0195] For example, the specific negative value of the difference between the outdoor supercooling and the indoor supercooling is -5 degrees Celsius.

[0196] The target defrosting pressure is 0.61 MPa.

[0197] In some embodiments, the target defrost temperature is:

[0198] T eo =b+k×T a

[0199] Where k and b are correction coefficients, and Ta is the third temperature.

[0200] Specifically, it is a correction factor, which is related to the air conditioning unit itself and can be determined during development and debugging.

[0201] For example, k is 0.5 to 1 and b is -4 to -7.

[0203] See Figure 13 As shown, in some embodiments, the control method for the air conditioning device includes:

[0204] S101, Obtain the first temperature, second temperature, third temperature and inhalation pressure.

If at least one of the first temperature and the second temperature is less than the target defrost temperature, and the suction pressure is less than the target defrost pressure, and the air conditioning device has been continuously heating for a first preset time, control the air conditioning device to enter the alternating defrost mode.

[0207] S104. If either the first temperature or the second temperature is greater than the target defrost temperature or the suction pressure is greater than the target defrost pressure, and this condition is maintained for a second preset time, the alternating defrost mode ends.

[0208] In this way, the automatic start and end of the alternating defrosting mode can be achieved through the control of the controller 1500.

[0209] Figure 14 This is a schematic flowchart illustrating the process of entering the alternating defrosting mode in the control method of the air conditioning device provided in the embodiments of this application.

[0210] See Figure 14 As shown, the control method of the air conditioning unit when switching defrosting modes includes:

[0211] S201. Compare the magnitudes of the first temperature and the second temperature.

[0212] S202. If the first temperature is greater than the second temperature, the air conditioning unit is controlled to use the second outdoor heat exchanger as the unit to be defrosted. If the first temperature is not greater than the second temperature, the air conditioning unit is controlled to use the first outdoor heat exchanger as the unit to be defrosted.

[0213] In this way, the outdoor heat exchanger that needs to be defrosted can be selected via the controller 1500.

[0214] Figure 15 This is another schematic diagram of the process when the air conditioning device provided in the embodiment of this application enters the alternating defrosting mode.

[0215] See Figure 15 As shown, the control method for the air conditioning device includes:

[0216] S203, Obtain the temperature of the object to be defrosted, the fourth temperature, and the exhaust pressure.

[0217] The temperature of the object to be defrosted is either the first temperature or the second temperature.

[0218] S204. The outdoor subcooling is obtained by subtracting the temperature of the object to be defrosted from the saturation temperature corresponding to the exhaust pressure.

[0219] S205. The indoor subcooling is obtained by subtracting the fourth temperature from the saturation temperature corresponding to the exhaust pressure.

[0220] S206. By controlling the opening degree of at least one of the first expansion valve, the second expansion valve and the third expansion valve, the value of the outdoor subcooling degree minus the indoor subcooling degree is made negative.

[0221] In this way, by adjusting the opening of the electronic expansion valve, with the subcooling degree as a reference, the amount of refrigerant passing through the outdoor heat exchanger and indoor heat exchanger 410 to be defrosted is controlled. The purpose is to ensure that there is enough refrigerant in the indoor heat exchanger 410 to meet the user's thermal comfort.
