The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0042] As shown in Figure 6 , the air conditioner 100 related to the present application can be a window type air conditioner, a cabinet type air conditioner or a wall-mounted type air conditioner, and the air conditioner 100 includes a casing 10, a compressor, an indoor side fan 804 and an indoor side heat exchanger 802, an outdoor side fan 803 and an outdoor side heat exchanger 801, and a flow channel mechanism. The flow channel mechanism includes a cold air flow channel 30 and a hot air flow channel 20, the cold air flow channel 30 has a cold air outlet 302, the casing 10 is provided with a cold air inlet 103 communicating with the cold air flow channel 30, the hot air flow channel 20 has a hot air outlet 201, and the casing 10 is provided with a hot air inlet 102 communicating with the hot air flow channel 20. The positions of the cold air flow channel 30 and the hot air flow channel 20 in the casing 10 can be analyzed specifically according to the situation.

[0043] When the air conditioner 100 is in the cooling mode, the cold air flow channel 30 is located at the indoor side of the air conditioner 100, the indoor side heat exchanger 802 is an evaporator, the cold air flow channel 30 is arranged close to the indoor side heat exchanger 802, the evaporator is arranged between the cold air flow channel 30 and the cold air inlet 103, the outdoor side heat exchanger 801 is a condenser, the condenser is arranged between the hot air flow channel 20 and the hot air inlet 102, the indoor side fan wheel 804 is arranged in the cold air flow channel 30, used to drive air to flow to the cold air flow channel 30 through the indoor side heat exchanger 802, and finally make the cold air blow out from the cold air outlet 302 of the cold air flow channel 30, realizing cooling, and the outdoor side fan wheel 803 is arranged in the hot air flow channel 20, used to exhaust hot air.

[0044] When the air conditioner 100 is in the heating mode, the indoor side heat exchanger 802 can be used as a condenser, the hot air flow channel 20 is arranged close to the indoor side heat exchanger 802, the outdoor side heat exchanger 801 can be used as an evaporator, the indoor side fan wheel 804 is arranged in the hot air flow channel 20, used to drive air to flow to the hot air flow channel 20 through the indoor side heat exchanger 802, and finally make the hot air blow out from the hot air outlet 201 of the hot air flow channel 20, realizing heating.

[0045] The control method of the air conditioner 100 according to the embodiment of the present application will be described below with reference to Figures 1-8

[0046] As shown in Figure 1 , the control method of the air conditioner 100 according to the embodiment of the present application comprises:

[0047] Step S1: obtaining the operating parameters of the air conditioner 100, the operating parameters including the indoor side wind speed of the air conditioner 100, the temperature difference between the indoor side inlet air temperature and the indoor side heat exchanger 802 temperature of the air conditioner 100.

[0048] The indoor side wind speed can refer to the rotating speed of the indoor side fan wheel 40, and the indoor side inlet air temperature can refer to the temperature at the indoor side air inlet. The indoor side wind speed, the indoor side inlet air temperature and the indoor side heat exchanger 802 temperature can be obtained by corresponding detection members, which can be sensors.

[0049] For example, a corresponding sensor can be arranged on the driving motor of the indoor side fan wheel 40, the rotating speed of the motor shaft is obtained through the sensor, so as to obtain the rotating speed of the indoor side fan wheel 40, and then obtain the indoor side wind speed. A corresponding temperature sensor can be arranged on the flow channel close to the indoor side heat exchanger 802 and on the indoor side heat exchanger 802, so as to detect the indoor side inlet air temperature and the indoor side heat exchanger 802 temperature. Specifically, when the indoor side heat exchanger 802 is an evaporator, the temperature sensor can be arranged on the pipeline of the evaporator, and the temperature on the pipeline is detected.

[0050] ​Of course, the detection member can also be other forms of detection member, not limited to a sensor, which will not be described here. Secondly, the operating parameter should be understood as not limited to including the indoor side air speed of the air conditioner 100, the temperature difference between the indoor side air inlet temperature and the indoor side heat exchanger 802 temperature of the air conditioner 100, and can also include other parameters.

[0051] Step S2: Obtain the outdoor side parameter of the air conditioner 100, which includes the outdoor temperature. The outdoor temperature of the air conditioner 100 can also be detected by a sensor, for example, a corresponding temperature sensor can be provided on the outside of the body 10 of the air conditioner 100 to obtain the outdoor temperature.

[0052] In addition, the outdoor side parameter of the air conditioner 100 should be understood as not limited to including the outdoor temperature, but can also include other parameters, such as outdoor air humidity.

[0053] Step S3: Adjust the compressor operating frequency of the air conditioner 100 according to the operating parameter and the outdoor side parameter. That is, the operating frequency of the compressor is controlled by at least three of the indoor side air speed, the temperature difference between the indoor side air inlet temperature and the indoor side heat exchanger 802 temperature, and the outdoor temperature, and a suitable compressor operating frequency can be selected.

[0054] The control method of the air conditioner 100 according to the embodiment of the application, by obtaining the operating parameter of the air conditioner 100, the operating parameter including the indoor side air speed of the air conditioner 100, the temperature difference between the indoor side air inlet temperature and the indoor side heat exchanger 802 temperature of the air conditioner 100, obtaining the outdoor side parameter of the air conditioner 100, the outdoor side parameter of the air conditioner 100 including the outdoor temperature, adjusting the compressor operating frequency of the air conditioner 100 according to the operating parameter and the outdoor side parameter, and selecting a suitable compressor operating frequency, can avoid the temperature of the electric control connected with the compressor being too high, can reduce the failure rate, and prolong the operating life of the air conditioner 100.

[0055] In some embodiments of the application, the air conditioner 100 is provided with at least one air speed interval. The air conditioner 100 can be provided with one air speed interval, or can be provided with multiple air speed intervals, which can be adaptively set according to specific conditions. For example, the air conditioner 100 is provided with two air speed intervals or three air speed intervals, etc.

[0056] In a specific example of the application, the air conditioner 100 can be provided with three air speed intervals, which are low air speed interval, medium air speed interval, and high air speed interval according to the air speed. The air speed range of the low air speed interval, the medium air speed interval, and the high air speed interval can be set according to the situation, which will not be described here.

[0057] According to the above, as Figure 2As shown, the step S3 of adjusting the compressor operating frequency of the air conditioner 100 according to the operating parameter and the outdoor-side parameter can include:

[0058] The step S31 of determining the wind speed interval of the indoor-side wind speed. After obtaining the indoor-side wind speed, the indoor-side wind speed can be determined to be located in which wind speed interval according to the current detected indoor-side wind speed. As described above, when the air conditioner 100 is set to have three wind speed intervals of low wind speed interval, medium wind speed interval and high wind speed interval, it can be determined that the indoor-side wind speed is located in which interval range of the low wind speed interval, the medium wind speed interval and the high wind speed interval.

[0059] The step S32 of adjusting the compressor operating frequency of the air conditioner 100 in the corresponding wind speed interval according to the temperature difference and the outdoor-side parameter. After determining the wind speed interval in which the indoor-side wind speed is located, the appropriate compressor operating frequency is adjusted according to the temperature difference and the outdoor-side parameter.

[0060] In some embodiments of the present application, the compressor has a plurality of frequency intervals, and the step of adjusting the compressor operating frequency of the air conditioner 100 in the corresponding wind speed interval includes adjusting the operating frequency of the compressor in one of the plurality of frequency intervals.

[0061] It can be understood that the compressor can be divided into three frequency intervals of low, medium and high according to the size of the operating frequency. After determining the wind speed interval in which the indoor-side wind speed is located, the operating frequency of the compressor can be controlled in any one of the three frequency intervals of low, medium and high according to the temperature difference and the outdoor-side parameter.

[0062] It should be noted that the three frequency intervals of low, medium and high of the compressor will be different according to the displacement of the compressor, which needs to be determined according to the specific situation. For example, in a certain type of air conditioner, the low frequency interval of the compressor can be 10-35 Hz, the medium frequency interval can be 35-50 Hz, and the high frequency interval can be 50-70 Hz. Of course, the frequency interval of the compressor is not limited to three, but can also be other numbers, for example, the frequency interval of the compressor can be roughly divided into two, or can be finely divided into four or more.

[0063] In some embodiments of the present invention, the indoor side of the air conditioner 100 has multiple temperature difference ranges, and the outdoor environment has multiple ambient temperature ranges. For example, the multiple temperature difference ranges may include a first temperature difference range, a second temperature difference range, and a third temperature difference range, where the temperature difference in the third temperature difference range is greater than the temperature difference in the second temperature difference range, and the temperature difference in the second temperature difference range is greater than the temperature difference in the first temperature difference range. When the air conditioner 100 is in cooling mode, the multiple ambient temperature ranges may include the first temperature range, the second temperature range, and the third temperature range, where the temperature in the third temperature range is greater than the temperature in the second temperature range, and the temperature in the second temperature range is greater than the temperature in the first temperature range.

[0064] Of course, the above are just examples. The number of temperature difference ranges is not limited to three and can be other numbers. The number of ambient temperature ranges is also not limited to three and can be other numbers, which will not be elaborated here.

[0065] like Figure 3 As shown, step S32 adjusts the compressor operating frequency of the air conditioner within the corresponding fan speed range based on the temperature difference and outdoor parameters, including:

[0066] Step S321: Determine the temperature range of the temperature difference and the ambient temperature range of the outdoor temperature. Referring to the example above, when multiple temperature difference ranges include a first temperature difference range, a second temperature difference range, and a third temperature difference range, and multiple ambient temperature ranges include a first temperature range, a second temperature range, and a third temperature range, after obtaining the temperature difference between the indoor air inlet temperature and the indoor heat exchanger 802 temperature, determine which temperature difference range the temperature difference falls within. Similarly, after obtaining the outdoor temperature, determine which temperature range the outdoor temperature falls within.

[0067] For example, the first temperature difference range can be less than 30℃, the second temperature range is 30 to 37℃ (inclusive), and the third temperature range is greater than or equal to 37℃. Alternatively, the first temperature difference range can be less than or equal to 10, the second temperature difference range can be 10 to 15 (inclusive), and the third temperature difference range can be 15 to 20 (inclusive).

[0068] Step S322: Adjust the compressor's operating frequency to one of several frequency ranges based on the temperature range and the ambient temperature range. By comprehensively considering both the temperature range and the ambient temperature range, a suitable compressor operating frequency can be selected. This avoids excessively high temperatures in the electrical components 40 connected to the compressor, reducing the failure rate and extending the service life of the air conditioner 100. See the table below for details, where Tc is the temperature difference between the indoor air intake temperature and the indoor heat exchanger 802 temperature of the air conditioner 100, Fr_low represents the low-frequency range of the compressor, Fr_medium represents the medium-frequency range of the compressor, and Fr_high represents the high-frequency range of the compressor.

[0069] Table 1

[0070]

[0071] As Figure 4 shown in some embodiments of the application, the compressor operating frequency of the air conditioner is adjusted according to the operating parameters and the outdoor side parameters, and further comprises:

[0072] Step S4: The cold air in the cold air flow channel 30 of the air conditioner 100 is introduced to the heat dissipation module of the electric control 40, and the electric control 40 is used to control the operating frequency of the compressor. That is, part of the cold air in the cold air flow channel 30 can be diverted to the electric control 40, and the diverted cold air can exchange heat when passing through the heat dissipation module, thereby improving the heat dissipation effect of the electric control 40, avoiding the temperature of the electric control 40 being too high, and enabling the compressor to operate better.

[0073] For example, the cold air flow channel 30 can be provided with a diversion port 301, which is arranged close to the heat dissipation module of the electric control 40. The air conditioner 100 further comprises a switching mechanism 50, which comprises a diversion part 501 and a motor connected to the diversion part 501. The motor drives the diversion part 501 to switch between an open state and a closed state, and is used to open or close the diversion port 301. When the diversion part 501 is in the open state, the diversion port 301 is opened, and the cold air in the cold air flow channel 30 is diverted to exchange heat with the heat dissipation module of the electric control 40.

[0074] It should be noted that the order of step S4 is not limited to being after step S3, but can also be executed before step S1. There is no definite order relationship between the other steps, which will not be described here.

[0075] As Figure 5 shown in some embodiments of the application, before obtaining the operating parameters of the air conditioner 100, further comprising:

[0076] Step S0: Control the compressor to operate at a preset frequency for a preset time. It can be understood that by controlling the compressor to operate at a preset frequency for a preset time, the temperature difference between the effective indoor side inlet air temperature and the indoor side heat exchanger 802 temperature can be obtained. The preset frequency can be the minimum operating frequency of the compressor, or other set frequency, which is not limited here. The preset time can also be set according to the needs, for example, the preset time can be 3min.

[0077] The following describes a specific embodiment of the control method of the air conditioner of the application in conjunction with the accompanying Figures 1 to 6

The cold air duct 30 is positioned close to the indoor heat exchanger 802, and the evaporator is located between the cold air duct 30 and the cold air inlet 103. The indoor fan 804 is located within the cold air duct 30 and is used to drive air through the indoor heat exchanger 802 to the cold air duct 30, ultimately causing cold air to be blown out from the cold air duct 30, thus achieving cooling. The outdoor heat exchanger 801 is a condenser, located between the hot air duct 20 and the hot air inlet 102. The outdoor fan 803 is located within the hot air duct 20 and is used to exhaust hot air.

[0081] The cold air flow channel 30 is provided with an air outlet 301, which is located near the heat dissipation module of the electrical control 40. The switching mechanism 50 includes an air outlet 501 and a motor connected to the air outlet 501. The motor drives the air outlet 501 to switch between an open state and a closed state to open or close the air outlet 301. When the air outlet 501 is in the open state, the air outlet 301 is opened to divert the cold air in the cold air flow channel 30 to exchange heat with the heat dissipation module of the electrical control 40.

[0082] like Figures 1 to 5 As shown, the control method for the air conditioner 100 includes the following steps:

[0085] Step S2: Obtain the outdoor side parameters of the air conditioner 100, including the outdoor temperature.

[0086] Step S3: Adjust the compressor operating frequency of air conditioner 100 according to the operating parameters and outdoor parameters.

[0087] The air conditioner 100 is arranged to include three wind speed intervals, which are low wind speed interval, medium wind speed interval and high wind speed interval according to the wind speed.

[0088] The first temperature difference interval is less than or equal to 10, the second temperature difference interval is 10-15 (including 15), and the third temperature difference interval is 15-20 (including 20). The first temperature difference interval is less than 30℃, the second temperature interval is 30-37℃ (including 30℃), and the third temperature interval is greater than or equal to 37℃.
