[0035] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0036] The indoor unit of the air conditioner, the air conditioner and the control method, medium and controller thereof according to the embodiment of the present invention are described in detail below in conjunction with the drawings and specific implementation methods of the specification.

[0037] Figure 1 FIG. 1 is a schematic diagram of an indoor unit of an air conditioner according to an embodiment of the present invention. Figure 1 As shown, the air conditioner also includes an outdoor unit 200, and the indoor unit 100 of the air conditioner includes: a driving device 10 and a fan 20; the driving device 10 is connected in the refrigerant circuit between the indoor unit 100 and the outdoor unit 200, and is used to drive the fan 20 to rotate under the action of the flowing refrigerant in the refrigerant circuit.

[0038] In order to solve the problem that the indoor unit 100 electronic control occupies space and has high cost, the embodiment of the present invention does not set the indoor unit electronic control in the indoor unit 100, and sets a driving device 10 in the refrigerant circuit between the indoor unit 100 and the outdoor unit 200. The driving device 10 is used to drive the fan 20 to rotate, thereby realizing the control of the air conditioner.

[0039] The embodiment of the present invention controls the driving device 10 to drive the fan 20 by starting the outdoor unit 200. Specifically, the compressor is started by starting the outdoor unit 200, and the operation of the compressor drives the refrigerant in the refrigerant circuit to flow. The driving device 10 can drive the fan 20 to rotate under the action of the flowing refrigerant, and the speed of the fan 20 driven by the driving device 10 can be adjusted by adjusting the flow speed of the refrigerant in the refrigerant circuit, thereby adjusting the air conditioner.

[0040] The indoor unit 100 of the air conditioner in the embodiment of the present invention has no indoor unit electronic control. By setting a driving device 10 in the refrigerant circuit between the indoor unit 100 and the outdoor unit 200, the driving device 10 drives the fan 20 to rotate under the action of the flowing refrigerant to achieve heat exchange of the heat exchanger in the indoor unit 100. The embodiment of the present invention reduces the indoor unit electronic control components, reduces the manufacturing cost of the air conditioner, reduces the manufacturing links, and achieves improved reliability and miniaturization of the air conditioner. In addition, the indoor unit 100 is not electrified, and the safety issues of electromagnetic radiation and high voltage danger are also solved.

[0041] In an embodiment of the present invention, the speed of the fan 20 can be adjusted by adjusting the flow rate of the refrigerant. Specifically, the speed of the fan 20 is positively correlated with the flow rate of the refrigerant in the refrigerant circuit. The faster the flow rate of the refrigerant, the faster the speed of the fan 20, and the slower the flow rate of the refrigerant, the slower the speed of the fan 20. The speed of the fan 20 can be controlled by adjusting at least one of the compressor and the electronic expansion valve in the outdoor unit 200.

[0042] In one embodiment of the present invention, the refrigerant inlet of the driving device 10 is connected to the outlet of the compressor through a refrigerant pipeline, and the refrigerant outlet of the driving device 10 is connected to the inlet of the evaporator 40 through a refrigerant pipeline.

[0043] It should be noted that the refrigerant circuit of the air conditioner includes a high-pressure refrigerant circuit and a low-pressure refrigerant circuit. Among them, one end of the high-pressure refrigerant circuit is connected to the outlet of the compressor in the outdoor unit 200, and the other end is connected to the inlet of the evaporator 40 in the indoor unit 100. One end of the low-pressure refrigerant circuit is connected to the outlet of the evaporator 40 in the indoor unit 100, and the other end is connected to the inlet of the compressor in the outdoor unit 200.

[0044] Specifically, the refrigerant inlet of the driving device 10 is connected to the outlet of the compressor through a refrigerant pipeline, and the refrigerant outlet is connected to the inlet of the evaporator 40 through a refrigerant pipeline. Figure 1The solid line connection between the middle outdoor unit 200, the drive device 10, and the evaporator 40 is a refrigerant pipeline connection. That is, the drive device 10 is set on the high-pressure refrigerant circuit. Since the refrigerant in the high-pressure refrigerant pipeline is under high pressure, the refrigerant is compressed, the flow resistance is small, and the flow rate is fast, while the refrigerant in the low-pressure refrigerant pipeline is under low pressure, and the flow rate is relatively slow. The drive device 10 can be set on the high-pressure refrigerant circuit to improve the driving effect of the drive device 10.

[0045] It should be noted that the embodiment of the present invention does not limit the position of the driving device 10. The driving device 10 can be arranged in a high-pressure refrigerant circuit or a low-pressure refrigerant circuit as required.

[0046] In one embodiment of the present invention, there are multiple refrigerant pipelines between the driving device 10 and the compressor in the outdoor unit 200, and at least one of the multiple refrigerant pipelines is provided with a flow rate regulating device 30 for regulating the flow rate of the refrigerant flowing in the corresponding refrigerant pipeline.

[0047] In one embodiment of the present invention, the flow rate regulating device 30 may be an electronic expansion valve.

[0048] Specifically, the refrigerant inlet of the driving device 10 is connected to the outlet of the compressor through a high-pressure refrigerant pipeline, and can also be directly connected to the outlet of the compressor through multiple refrigerant pipelines. A flow rate regulating device 30 is provided on at least one of the multiple refrigerant pipelines. The flow rate of the refrigerant flowing in the corresponding refrigerant pipeline is regulated by regulating the flow rate regulating device 30 on the relevant refrigerant pipeline. When adjusting the speed of the fan 20, the speed of the fan 20 can be controlled by adjusting the flow rate regulating device 30.

[0049] In a specific embodiment, if Figure 2 As shown, the driving device 10 adopts a dual-channel refrigerant pipeline method. Specifically, the refrigerant inlet of the driving device 10 is connected to the outlet of the compressor through a high-pressure refrigerant pipeline, and the refrigerant inlet of the driving device 10 is also directly connected to the outlet of the compressor through a first refrigerant pipeline. A flow rate regulating device 30 is provided on the first refrigerant pipeline to adjust the flow rate of the refrigerant flowing in the first refrigerant pipeline through the flow rate regulating device 30. Among them, when adjusting the speed of the fan 20, the speed of the fan 20 can be controlled by adjusting the flow rate regulating device 30 and at least one of the compressor and the electronic expansion valve in the outdoor unit 200.

[0050] In one embodiment of the present invention, the indoor unit 100 also includes a temperature detection device, which is used to detect the refrigerant temperature at the refrigerant outlet of the indoor unit 100 and send the refrigerant temperature to the outdoor unit 200, so that the outdoor unit 200 controls at least one of the flow rate regulating device 30, the compressor in the outdoor unit 200, and the electronic expansion valve according to the refrigerant temperature.

[0051] Since the refrigerant temperature at the refrigerant outlet of the indoor unit 100 can reflect the temperature of the indoor unit pipe, that is, the refrigerant temperature returned from the indoor unit 100 can be detected in the indoor unit 100 to indirectly detect the temperature of the indoor unit pipe. In order to avoid the indoor unit pipe temperature being too low or too high to affect the performance and comfort of the air conditioner. The outdoor unit 200 can obtain the refrigerant temperature at the refrigerant outlet of the indoor unit 100 detected by the temperature detection device, and control at least one of the flow rate regulating device 30, the compressor in the outdoor unit 200, and the electronic expansion valve according to the refrigerant temperature, adjust the refrigerant flow rate and the refrigerant temperature, and realize the control of the indoor unit pipe temperature.

[0052] It is feasible to set a preset temperature threshold range to determine whether the refrigerant temperature detected by the temperature detection device is within the preset temperature threshold range. If the refrigerant temperature is within the preset temperature threshold range, at least one of the compressor and the electronic expansion valve may not be adjusted. If the refrigerant temperature is lower than the lower limit of the preset temperature threshold range or higher than the upper limit of the preset temperature threshold range, the operating frequency of the compressor and / or the opening of the electronic expansion valve are recalculated, and the operating frequency of the compressor and / or the opening of the electronic expansion valve are adjusted according to the calculated operating frequency of the compressor and / or the opening of the electronic expansion valve, so that the internal machine pipe temperature is maintained within the preset temperature threshold range.

[0053] In one embodiment of the present invention, Figure 3 As shown, the driving device 10 may include a driving mechanism 11 and a magnetic transmission mechanism 12, wherein the driving mechanism 11 is used to drive the magnetic transmission mechanism 12 to rotate under the action of the flowing refrigerant, so as to drive the fan 20 to rotate, wherein the fan 20 is physically isolated from the magnetic transmission mechanism 12.

[0054] In order to ensure the sealing of the refrigerant system, the driving device 10 and the fan 20 in the embodiment of the present invention adopt magnetic attraction transmission technology. Figure 1 The dotted line connection between the middle drive device 10 and the fan 20 is a magnetic attraction transmission connection. Figure 3 The arrows in the middle driving device 10 indicate the flow direction of the refrigerant.

[0055] Specifically, the driving mechanism 11 and the magnetic transmission mechanism 12 are packaged in the refrigerant pipeline system component, and a fan 20 is arranged outside the refrigerant pipeline system component at a position corresponding to one end of the magnetic transmission mechanism 12, see Figure 3 The driving device 10 and the fan 20 are physically isolated from each other, which can effectively ensure the sealing of the refrigerant system. The driving mechanism 11 rotates under the action of the flowing refrigerant, and drives the magnetic attraction transmission mechanism 12 to rotate, and the rotation of the magnetic attraction transmission mechanism 12 drives the fan 20 to rotate.

[0056] The driving device 10 in the embodiment of the present invention is connected to the fan 20 by magnetic attraction transmission. The driving mechanism 11 and the magnetic attraction transmission mechanism 12 are encapsulated in the refrigerant pipeline system component, and the fan 20 is arranged outside the refrigerant pipeline system component corresponding to the magnetic attraction transmission mechanism 12, which effectively ensures the sealing of the refrigerant system.

[0057] In one embodiment of the present invention, the outdoor unit 200 can be started by a remote controller. The remote controller is wirelessly connected to the outdoor unit 200. When the air conditioner is started, a command to start the outdoor unit 200 is sent to the outdoor unit 200 through the remote controller to start the outdoor unit 200. When the air conditioner is turned off, a command to turn off the outdoor unit 200 is sent to the outdoor unit 200 through the remote controller to turn off the outdoor unit 200.

[0058] It should be noted that, in controlling the opening and closing of the outdoor unit 200, smart electronic devices such as mobile phones and smart speakers can also be used to establish wireless communication with the outdoor unit 200 to achieve control over the opening and closing of the outdoor unit 200.

[0059] In the embodiment of the present invention, the remote controller directly realizes wireless communication with the outdoor unit 200, which can not only control the opening and closing of the outdoor unit 200, but also collect the indoor ambient temperature.

[0060] It is feasible to set a temperature sensor for collecting the indoor ambient temperature on the remote controller. The remote controller sends the collected indoor ambient temperature to the outdoor unit 200. The outdoor unit 200 controls at least one of the flow rate regulating device 30, the compressor in the outdoor unit 200, and the electronic expansion valve according to the indoor ambient temperature and the target temperature to adjust the indoor ambient temperature.

[0061] In an embodiment of the present invention, when the remote controller directly realizes wireless communication with the outdoor unit 200, LoRa spread spectrum technology can be used to realize ultra-high anti-interference and ultra-long-distance (strong wall penetration capability) wireless communication.

[0062] It should be noted that LoRa (Long Range Radio) spread spectrum technology has strong anti-interference ability. The general GFSK (Gaussian Frequency Shift Keying) receiver requires a minimum signal-to-noise ratio (SNR) of 8dB to demodulate the signal, while the LoRa receiver only needs a minimum signal-to-noise ratio of -20dB to demodulate the signal. The demodulation signal-to-noise ratio difference between GFSK modulation and LoRa modulation is 28dB. The highest sensitivity is up to -137dBm. At the same time, LoRa spread spectrum technology has the characteristics of ultra-low power consumption. Specifically, the wireless transmission transient current is 5.8mA. The standby mode is 0.85μA. The shutdown current is 150nA (wake up when an external event occurs).

[0063] The indoor unit 100 of the air conditioner of the embodiment of the present invention uses the driving device 10 to drive the fan 20 to rotate, thereby reducing the number of electronic control components of the indoor unit, reducing the manufacturing cost of the air conditioner, reducing the manufacturing links, and achieving improved reliability and miniaturization of the air conditioner. In addition, the indoor unit is not electrified, and the safety issues of electromagnetic radiation and high voltage danger are also solved.

[0064] The invention provides an air conditioner.

[0065] Figure 4 Schematic diagram of an air conditioner according to an embodiment of the present invention. Figure 4 As shown, the air conditioner 1000 includes: an outdoor unit 200, and the indoor unit 100 of the air conditioner 1000 as described above.

[0066] In the embodiment of the present invention, a driving device 10 and a fan 20 are provided in the indoor unit 100, and the driving device 10 is connected to the refrigerant circuit between the indoor unit 100 and the outdoor unit 200. The driving device 10 drives the fan 20 to rotate under the action of the refrigerant flowing in the refrigerant circuit.

[0067] The embodiment of the present invention does not set the indoor unit electric control in the indoor unit 100, and sets the driving device 10 in the refrigerant circuit between the indoor unit 100 and the outdoor unit 200, and uses the driving device 10 to drive the fan 20 to rotate, so as to control the air conditioner. The indoor unit 100 of the embodiment of the present invention solves the problem that the indoor unit 100 electric control occupies space and has high cost.

[0068] The embodiment of the present invention controls the driving device 10 to drive the fan 20 by starting the outdoor unit 200. Specifically, the compressor in the outdoor unit 200 is started, and the operation of the compressor drives the refrigerant in the refrigerant circuit to flow. The driving device 10 can drive the fan 20 to rotate under the action of the flowing refrigerant, and the speed of the fan 20 driven by the driving device 10 can be adjusted by adjusting the flow speed of the refrigerant in the refrigerant circuit, thereby adjusting the air conditioner.

[0069] In one embodiment of the present invention, the driving device 10 may include a driving mechanism 11 and a magnetic transmission mechanism 12, wherein the driving mechanism 11 is used to drive the magnetic transmission mechanism 12 to rotate under the action of the flowing refrigerant, so as to drive the fan 20 to rotate, wherein the fan 20 is physically isolated from the magnetic transmission mechanism 12.

[0070] In order to ensure the sealing of the refrigerant system, the driving device 10 and the fan 20 in the embodiment of the present invention adopt magnetic attraction transmission technology. Figure 1 The dotted line connection between the middle drive device 10 and the fan 20 is a magnetic attraction transmission connection. Figure 3 The arrows in the middle driving device 10 indicate the flow direction of the refrigerant.

[0071] Specifically, the driving mechanism 11 and the magnetic transmission mechanism 12 are packaged in the refrigerant pipeline system component, and a fan 20 is arranged outside the refrigerant pipeline system component at a position corresponding to one end of the magnetic transmission mechanism 12, see Figure 3 The driving device 10 and the fan 20 are physically isolated from each other, which can effectively ensure the sealing of the refrigerant system. The driving mechanism 11 rotates under the action of the flowing refrigerant, and drives the magnetic attraction transmission mechanism 12 to rotate, and the rotation of the magnetic attraction transmission mechanism 12 drives the fan 20 to rotate.

[0072] The driving device 10 in the embodiment of the present invention is connected to the fan 20 by magnetic attraction transmission. The driving mechanism 11 and the magnetic attraction transmission mechanism 12 are encapsulated in the refrigerant pipeline system component, and the fan 20 is arranged outside the refrigerant pipeline system component corresponding to the magnetic attraction transmission mechanism 12, which effectively ensures the sealing of the refrigerant system.

[0073] In one embodiment of the present invention, the refrigerant inlet of the driving device 10 is connected to the outlet of the compressor through a refrigerant pipeline, and the refrigerant outlet of the driving device 10 is connected to the inlet of the evaporator 40 through a refrigerant pipeline.

[0074] It should be noted that the refrigerant circuit of the air conditioner includes a high-pressure refrigerant circuit and a low-pressure refrigerant circuit. Among them, one end of the high-pressure refrigerant circuit is connected to the outlet of the compressor in the outdoor unit 200, and the other end is connected to the inlet of the evaporator 40 in the indoor unit 100. One end of the low-pressure refrigerant circuit is connected to the outlet of the evaporator 40 in the indoor unit 100, and the other end is connected to the inlet of the compressor in the outdoor unit 200.

[0075] Specifically, the refrigerant inlet of the driving device 10 is connected to the outlet of the compressor through a refrigerant pipeline, and the refrigerant outlet is connected to the inlet of the evaporator 40 through a refrigerant pipeline. Figure 1 The solid line connection between the middle outdoor unit 200, the drive device 10, and the evaporator 40 is a refrigerant pipeline connection. That is, the drive device 10 is set on the high-pressure refrigerant circuit. Since the refrigerant in the high-pressure refrigerant pipeline is under high pressure, the refrigerant is compressed, the flow resistance is small, and the flow rate is fast, while the refrigerant in the low-pressure refrigerant pipeline is under low pressure, and the flow rate is relatively slow. The drive device 10 can be set on the high-pressure refrigerant circuit to improve the driving effect of the drive device 10.

[0076] It should be noted that the embodiment of the present invention does not limit the position of the driving device 10. The driving device 10 can be arranged in a high-pressure refrigerant circuit or a low-pressure refrigerant circuit as required.

[0077] In one embodiment of the present invention, there are multiple refrigerant pipelines between the driving device 10 and the compressor in the outdoor unit 200, and at least one of the multiple refrigerant pipelines is provided with a flow rate regulating device 30 for regulating the flow rate of the refrigerant flowing in the corresponding refrigerant pipeline.

[0078] In one embodiment of the present invention, the flow rate regulating device 30 may be an electronic expansion valve.

[0079] Specifically, the refrigerant inlet of the driving device 10 is connected to the outlet of the compressor through a high-pressure refrigerant pipeline, and can also be directly connected to the outlet of the compressor through multiple refrigerant pipelines. A flow rate regulating device 30 is provided on at least one of the multiple refrigerant pipelines. The flow rate of the refrigerant flowing in the corresponding refrigerant pipeline is adjusted by adjusting the flow rate regulating device 30 on the relevant refrigerant pipeline. When adjusting the speed of the fan 20, the speed of the fan 20 can be controlled by adjusting the flow rate regulating device.

[0080] The indoor unit of the air conditioner in the embodiment of the present invention has no indoor unit electronic control. By setting a driving device 10 in the refrigerant circuit between the indoor unit 100 and the outdoor unit 200, the driving device 10 drives the fan 20 to rotate under the action of the flowing refrigerant, thereby realizing the heat exchange of the heat exchanger in the indoor unit 100. The embodiment of the present invention reduces the indoor unit electronic control components, reduces the manufacturing cost of the air conditioner 1000, reduces the manufacturing links, and realizes the improvement of reliability and the miniaturization of the air conditioner. In addition, the indoor unit 100 is not electrified, and the safety issues of electromagnetic radiation and high voltage danger are also solved.

[0081] In one embodiment of the present invention, the air conditioner 100 also includes: a remote controller 300 for controlling the opening and closing of the outdoor unit 200, and sending the indoor ambient temperature to the outdoor unit 200, so that the outdoor unit 200 controls at least one of the flow rate regulating device 30, the compressor in the outdoor unit 100, and the electronic expansion valve according to the indoor ambient temperature.

[0082] Specifically, the remote controller 300 directly communicates with the outdoor unit 200 wirelessly, and can not only control the outdoor unit 200 to be turned on and off, but also collect the indoor ambient temperature. It is feasible to set a temperature sensor for collecting the indoor ambient temperature on the remote controller 300. The remote controller 300 sends the collected indoor ambient temperature to the outdoor unit 200. The outdoor unit 200 controls at least one of the flow rate regulating device 30, the compressor in the outdoor unit 200, and the electronic expansion valve according to the indoor ambient temperature and the target temperature, so as to adjust the indoor ambient temperature.

[0083] In an embodiment of the present invention, the remote controller 300 and the outdoor unit 200 realize wireless communication, and LoRa spread spectrum technology can be used to realize ultra-high anti-interference and ultra-long-distance (strong wall penetration ability) wireless communication.

[0084] It should be noted that LoRa spread spectrum technology has strong anti-interference ability. The general GFSK (Gaussian Frequency Shift Keying) receiver requires a minimum signal-to-noise ratio (SNR) of 8dB to demodulate the signal, while the LoRa receiver only needs a minimum signal-to-noise ratio of -20dB to demodulate the signal. The demodulation signal-to-noise ratio difference between GFSK modulation and LoRa modulation is 28dB. The highest sensitivity is up to -137dBm. At the same time, LoRa spread spectrum technology has the characteristics of ultra-low power consumption. Specifically, the wireless transmission transient current is 5.8mA. The standby mode is 0.85μA. The shutdown current is 150nA (wake up when an external event occurs).

[0085] In one embodiment of the present invention, the outdoor unit 200 also includes a controller, which is used to detect the refrigerant temperature at the refrigerant outlet of the indoor unit and control at least one of the flow rate regulating device 30, the compressor in the outdoor unit 200, and the electronic expansion valve according to the refrigerant temperature.

[0086] Specifically, since the refrigerant temperature at the refrigerant outlet of the indoor unit 100 can reflect the temperature of the indoor unit pipe, that is, the refrigerant temperature returned from the indoor unit 100 can be detected in the outdoor unit 200 to indirectly detect the temperature of the indoor unit pipe. In order to prevent the indoor unit pipe temperature from being too low or too high and affecting the performance and comfort of the air conditioner, the controller can obtain the refrigerant temperature at the refrigerant outlet of the indoor unit 100 detected by the temperature detection device, and control at least one of the flow rate regulating device 30, the compressor in the outdoor unit 200, and the electronic expansion valve according to the refrigerant temperature, adjust the refrigerant flow rate and the refrigerant temperature, and realize the control of the indoor unit pipe temperature. Among them, the temperature detection device is used to detect the refrigerant temperature at the refrigerant outlet of the indoor unit 100.

[0087] It is feasible to set a preset temperature threshold range to determine whether the refrigerant temperature detected by the temperature detection device is within the preset temperature threshold range. If the refrigerant temperature is within the preset temperature threshold range, at least one of the compressor and the electronic expansion valve may not be adjusted. If the refrigerant temperature is lower than the lower limit of the preset temperature threshold range or higher than the upper limit of the preset temperature threshold range, the operating frequency of the compressor and / or the opening of the electronic expansion valve are recalculated, and the operating frequency of the compressor and / or the opening of the electronic expansion valve are adjusted according to the calculated operating frequency of the compressor and / or the opening of the electronic expansion valve, so that the internal machine pipe temperature is maintained within the preset temperature threshold range.

[0088] The air conditioner of the embodiment of the present invention adopts an indoor unit without an indoor electronic control. The indoor unit uses a driving device to drive the fan to rotate, which reduces the indoor electronic control components, reduces the manufacturing cost of the air conditioner, reduces the manufacturing links, and achieves improved reliability and miniaturization of the air conditioner. In addition, the indoor unit is not electrified, and the safety issues of electromagnetic radiation and high voltage danger are also solved.

[0089] The invention provides a control method for an air conditioner.

[0090] The air conditioner of the embodiment of the present invention includes an indoor unit and an outdoor unit. The indoor unit includes: a driving device and a fan. The driving device is connected in the refrigerant circuit between the indoor unit and the outdoor unit, and is used to drive the fan to rotate under the action of the flowing refrigerant in the refrigerant circuit.

[0091] Specifically, the air conditioner includes an outdoor unit and an indoor unit as described above. A driving device is provided in the indoor unit, and the driving device is connected to the refrigerant circuit between the indoor unit and the outdoor unit. The compressor in the outdoor unit can be started by a remote controller to drive the refrigerant in the refrigerant circuit to flow, and the driving device can drive the fan to rotate under the action of the flowing refrigerant to realize the heat exchange of the heat exchanger in the indoor unit.

[0092] Figure 5 FIG. 1 is a flow chart of a method for controlling an air conditioner according to an embodiment of the present invention. Figure 5 As shown, the control method of the air conditioner may include:

[0093] S101, obtaining indoor ambient temperature;

[0094] S102, controlling the compressor and / or the electronic expansion valve in the outdoor unit according to the indoor ambient temperature, so as to drive the fan to rotate through a driving device to adjust the indoor ambient temperature.

[0095] In a feasible embodiment, the remote controller can directly communicate with the outdoor unit wirelessly, and can not only control the outdoor unit to turn on and off, but also collect the indoor ambient temperature. It is feasible to set a temperature sensor for collecting the indoor ambient temperature on the remote controller.

[0096] As a specific embodiment, the indoor ambient temperature collected by the remote control can be obtained, and the operating frequency of the compressor in the outdoor unit can be controlled according to the indoor ambient temperature. The flow rate and temperature of the refrigerant flowing in the refrigerant circuit can be controlled by controlling the operating frequency of the compressor, and the driving speed of the driving device can be adjusted to adjust the speed of the fan through the driving device to achieve the adjustment of the indoor ambient temperature.

[0097] As another specific embodiment, the opening of the electronic expansion valve in the outdoor unit can be controlled according to the indoor ambient temperature. By controlling the opening of the electronic expansion valve, the flow rate and temperature of the refrigerant flowing in the refrigerant circuit can be controlled to adjust the driving speed of the driving device.

[0098] As another specific embodiment, the operating frequency of the compressor in the outdoor unit and the opening of the electronic expansion valve can be controlled according to the indoor ambient temperature. By controlling the operating frequency of the compressor and the opening of the electronic expansion valve, the flow rate and temperature of the refrigerant flowing in the refrigerant circuit can be controlled to adjust the driving speed of the driving device.

[0099] In one embodiment of the present invention, there are multiple refrigerant pipelines between the driving device and the compressor, and at least one of the multiple refrigerant pipelines is provided with a flow rate regulating device for regulating the flow rate of the refrigerant flowing in the corresponding refrigerant pipeline; the control method of the air conditioner may also include: controlling at least one of the flow rate regulating device, the compressor in the outdoor unit, and the electronic expansion valve according to the indoor ambient temperature.

[0100] In one embodiment of the present invention, the refrigerant inlet of the driving device is connected to the outlet of the compressor through a refrigerant pipeline, and the refrigerant outlet of the driving device is connected to the inlet of the evaporator through a refrigerant pipeline.

[0101] It should be noted that the refrigerant circuit of the air conditioner includes a high-pressure refrigerant circuit and a low-pressure refrigerant circuit. Among them, one end of the high-pressure refrigerant circuit is connected to the outlet of the compressor in the outdoor unit, and the other end is connected to the inlet of the evaporator in the indoor unit. One end of the low-pressure refrigerant circuit is connected to the outlet of the evaporator in the indoor unit, and the other end is connected to the inlet of the compressor in the outdoor unit.

[0102] Specifically, the refrigerant inlet of the driving device is connected to the outlet of the compressor through the refrigerant pipeline, and the refrigerant outlet is connected to the inlet of the evaporator through the refrigerant pipeline. That is, the driving device is set on the high-pressure refrigerant circuit. Since the refrigerant in the high-pressure refrigerant pipeline is under high pressure, the refrigerant is compressed, the flow resistance is small, and the flow rate is fast, while the refrigerant in the low-pressure refrigerant pipeline is under low pressure, and the flow rate is relatively slow. The driving device can be set on the high-pressure refrigerant circuit to improve the driving effect of the driving device.

[0103] As a specific embodiment, the driving device is arranged on the high-pressure refrigerant circuit. When adjusting the speed of the fan, the speed of the fan can be controlled by adjusting at least one of the compressor and the electronic expansion valve in the outdoor unit, and the indoor ambient temperature can be adjusted by adjusting the speed of the fan.

[0104] In one embodiment of the present invention, there are multiple refrigerant pipelines between the driving device and the compressor in the outdoor unit, and at least one of the multiple refrigerant pipelines is provided with a flow rate regulating device for regulating the flow rate of the refrigerant flowing in the corresponding refrigerant pipeline.

[0105] Specifically, the refrigerant inlet of the driving device is connected to the outlet of the compressor through a high-pressure refrigerant pipeline, and can also be directly connected to the outlet of the compressor through multiple refrigerant pipelines. A flow rate regulating device is provided on at least one of the multiple refrigerant pipelines. The flow rate of the refrigerant flowing in the corresponding refrigerant pipeline is adjusted by adjusting the flow rate regulating device on the relevant refrigerant pipeline. When adjusting the speed of the fan, the speed of the fan can be controlled by adjusting the flow rate regulating device.

[0106] In a specific embodiment, if Figure 2 As shown, the driving device adopts a dual-channel refrigerant pipeline method. Specifically, the refrigerant inlet of the driving device is connected to the outlet of the compressor through a high-pressure refrigerant pipeline, and the refrigerant inlet of the driving device 10 is also directly connected to the outlet of the compressor through a first refrigerant pipeline. A flow rate regulating device is provided on the first refrigerant pipeline to adjust the flow rate of the refrigerant flowing in the first refrigerant pipeline through the flow rate regulating device. Among them, when adjusting the speed of the fan, the speed of the fan can be controlled by adjusting the flow rate regulating device and at least one of the compressor and the electronic expansion valve in the outdoor unit, and the indoor ambient temperature can be adjusted by adjusting the speed of the fan.

[0107] In one embodiment of the present invention, Figure 6 As shown, the control method of the air conditioner may include:

[0108] S201, obtaining the refrigerant temperature at the refrigerant outlet of the indoor unit;

[0109] S202, controlling at least one of the flow rate regulating device, the compressor in the outdoor unit, and the electronic expansion valve according to the refrigerant temperature.

[0110] In a feasible embodiment, the indoor unit further includes a temperature detection device, and the temperature detection device is used to detect the refrigerant temperature at the refrigerant outlet of the indoor unit.

[0111] Since the refrigerant temperature at the refrigerant outlet of the indoor unit can reflect the temperature of the indoor unit pipe, that is, the refrigerant temperature returned from the indoor unit can be detected in the outdoor unit to indirectly detect the temperature of the indoor unit pipe. In order to prevent the indoor unit pipe temperature from being too low or too high and affecting the performance and comfort of the air conditioner, a temperature detection device can be used to detect the refrigerant temperature at the refrigerant outlet of the indoor unit, and at least one of the flow rate regulating device, the compressor in the outdoor unit, and the electronic expansion valve can be controlled according to the refrigerant temperature to adjust the refrigerant flow rate and the refrigerant temperature to achieve control of the indoor unit pipe temperature.

[0112] In a specific embodiment of the present invention, Figure 7As shown, after the outdoor unit receives the start command sent by the remote controller, the compressor is started to work, driving the refrigerant in the refrigerant circuit to flow, and the driving device can drive the fan to rotate under the action of the flowing refrigerant. The operating frequency of the compressor and / or the opening of the electronic expansion valve are controlled according to the current indoor ambient temperature and the target indoor ambient temperature to adjust the speed of the fan, realize the adjustment of the cooling capacity and flow rate, and adjust the indoor ambient temperature to the target indoor ambient temperature.

[0113] In the process of adjusting the indoor ambient temperature, in order to avoid the indoor unit pipe temperature being too low or too high to affect the performance and comfort of the air conditioner, the refrigerant temperature at the refrigerant outlet of the indoor unit is detected to determine whether the refrigerant temperature at the refrigerant outlet of the indoor unit is within the preset temperature threshold range. If the refrigerant temperature is lower than the lower limit of the preset temperature threshold range or higher than the upper limit of the preset temperature threshold range, the operating frequency of the compressor and / or the opening of the electronic expansion valve are recalculated, and the operating frequency of the compressor and / or the opening of the electronic expansion valve are adjusted according to the calculated operating frequency of the compressor and / or the opening of the electronic expansion valve to maintain the indoor unit pipe temperature within the preset temperature threshold range.

[0114] The control method of the air conditioner according to the embodiment of the present invention is used for an air conditioner having an indoor unit without an indoor unit electronic control, to realize the control of the air conditioner.

[0115] In the control method of the air conditioner of the embodiment of the present invention, the indoor unit has no electronic control, and the indoor ambient temperature is collected by using the temperature sensor in the remote control. The compressor and / or the electronic expansion valve in the outdoor unit are controlled according to the collected indoor ambient temperature, so that the fan is driven to rotate through the driving device to achieve the adjustment of the indoor ambient temperature.
