[0027] Please see Figure 1 , Figure 1 This is a flowchart illustrating the control method for an air conditioner provided in an embodiment of the present invention. The control method for the air conditioner will be described in detail below. Figure 1 As shown, the method includes the following steps S110-S120.

[0028] S110: Obtain compressor frequency, PTC resistance temperature, and outdoor fan windshield.

[0029] In this embodiment of the invention, the air conditioner includes an outdoor unit and a compressor, and the outdoor unit further includes an outdoor fan. After the air conditioner is turned on, the outdoor fan and compressor run. After running for time t0, the main control unit in the outdoor unit triggers the temperature sensor to obtain the heating temperature value of the PTC resistor on the outdoor unit's main board, which is the PTC resistor temperature T. PTC In addition to obtaining the temperature T of the PTC resistor PTC In addition, the compressor frequency and the outdoor fan speed are also acquired. The outdoor fan speed determines the outdoor fan damper. Understandably, if the outdoor fan speed is less than a first preset speed value, it indicates that the outdoor fan damper is at a low damper setting, and the outdoor fan damper identifier is set to a low damper identifier; if the outdoor fan speed is not less than the first preset speed value and is less than a second preset speed value, it indicates that the outdoor fan damper is at a medium damper setting, and the outdoor fan damper identifier is set to a medium damper identifier; if the outdoor fan speed is not less than the second preset speed value, it indicates that the outdoor fan damper is at a high damper setting, and the outdoor fan damper identifier is set to a high damper identifier. It should be noted that in this embodiment, t0 is 30 seconds, meaning that air circulation begins after the air conditioner has been running for 30 seconds; in other embodiments, t0 can be set according to actual needs and is not specifically limited. It should also be noted that both the first preset speed value and the second preset speed value can be set according to actual needs.

[0030] S120. Calculate the outer ring temperature based on the compressor frequency, the PTC resistor temperature, and the outdoor fan windshield, and control the air conditioner operation based on the outer ring temperature.

[0031] In this embodiment of the invention, after obtaining the compressor frequency, the PTC resistor temperature, and the outdoor fan baffle, the outer ring temperature is calculated based on the compressor frequency, the PTC resistor temperature, and the outdoor fan baffle, and the air conditioner is controlled to operate based on the outer ring temperature. Understandably, the outer ring temperature is the outdoor ambient temperature.

[0032] In some embodiments, such as this embodiment, as Figure 2 As shown, step S120 may include steps S121-S123.

[0033] S121. If the compressor frequency is less than the first preset frequency threshold, the outer ring temperature is calculated based on the PTC resistance temperature, the external fan windshield, the preset compressor low-frequency correction temperature, and the preset windshield correction temperature.

[0034] S122. If the compressor frequency is not less than the first preset frequency threshold and less than the second preset frequency threshold, then the outer ring temperature is calculated based on the PTC resistance temperature, the external fan windshield, the preset compressor intermediate frequency correction temperature, and the preset windshield correction temperature.

[0035] S123. If the compressor frequency is not less than the second preset frequency threshold, the outer ring temperature is calculated based on the PTC resistance temperature, the external fan windshield, the preset compressor high-frequency correction temperature, and the preset windshield correction temperature.

[0036] In this embodiment of the invention, for ease of understanding, it is assumed that the compressor frequency is F. 频率 The system determines whether the compressor frequency is less than a first preset frequency threshold, where the first preset frequency threshold is 30Hz; if the compressor frequency is less than the first preset frequency threshold, i.e., if F 频率 <30Hz indicates that the compressor is operating at a low frequency. The outer ring temperature is then calculated based on the PTC resistor temperature, the external fan baffle, the preset compressor low-frequency correction temperature, and the preset baffle correction temperature. If the compressor frequency is not less than the first preset frequency threshold, then it is further determined whether the compressor frequency is less than a second preset frequency threshold, where the second preset frequency threshold is 60Hz. If the compressor frequency is less than the second preset frequency threshold, i.e., if 30Hz ≤ F... 频率 <60Hz indicates that the compressor is operating at a medium frequency. The outer ring temperature is then calculated based on the PTC resistor temperature, the external fan damper, the preset compressor medium frequency correction temperature, and the preset damper correction temperature. If the compressor frequency is not less than the second preset frequency threshold, i.e., if F... 频率 ≥60Hz indicates that the compressor is operating at a high frequency. The outer ring temperature is then calculated based on the PTC resistor temperature, the external fan baffle, the preset high-frequency correction temperature of the compressor, and the preset baffle correction temperature. It should be noted that in other embodiments, the values ​​of the first preset frequency threshold and the second preset frequency threshold can be set according to actual needs and are not specifically limited here. It should also be noted that, assuming the preset low-frequency correction temperature, the preset medium-frequency correction temperature, and the preset high-frequency correction temperature of the compressor are ΔT1, ΔT2, and ΔT3 respectively, in this embodiment, ΔT3 > ΔT2 > ΔT1. The reason for setting ΔT3 > ΔT2 > ΔT1 is that ΔT3 is the correction temperature when the compressor is at a high frequency, ΔT2 is the correction temperature when the compressor is at a medium frequency, and ΔT1 is the correction temperature when the compressor is at a low frequency. The higher the frequency of the compressor, the higher the PTC resistor temperature, and the higher the correction temperature needs to be set.

[0058] For ease of understanding, let's assume that ΔT1 is 5℃, ΔT2 is 10℃, ΔT3 is 20℃, ΔT4 is 5℃, ΔT5 is 10℃, and ΔT6 is 15℃. If F 频率 <30Hz and the external fan damper is at its low setting, T is detected. PTC =45℃, T 外环 =T PTC -△T1+△T4=45℃-5℃+5℃=40℃; if F 频率 <30Hz and the external fan damper is set to medium speed, T is measured. PTC =35℃, T外环 =T PTC -△T1+△T5=35℃-5℃+10℃=40℃, if F 频率 <30Hz and the external fan damper is at the high setting, T is detected. PTC =30℃, T 外环 =T PTC -△T1+△T5=30℃-5℃+15℃=40℃; if 30Hz≤F 频率 <60Hz and the external fan damper is at its low setting, T is detected. PTC =50℃, T 外环 =T PTC -△T2+△T4=45℃-10℃+5℃=40℃; if 30Hz≤F 频率 <60Hz and the external fan windshield is at the medium speed setting, T is measured.

PTC =40℃, T 外环 =T PTC -△T2+△T4=35℃-10℃+15℃=40℃; if F 频率 ≥60Hz and the external fan damper is at low speed, T is tested. PTC =55℃, T 外环 =T PTC -△T3+△T4=55℃-20℃+5℃=40℃; If F 频率 ≥60Hz and the external fan windshield is at the medium windshield setting, T is tested. PTC =50℃, T 外环 =T PTC -△T3+△T4=50℃-20℃+10℃=40℃; if F 频率 ≥60Hz and the external fan windshield is at the high setting, T is tested. PTC =45℃, T 外环 =T PTC -△T3 + △T4 = 45℃ - 20℃ + 15℃ = 40℃. From the above, it can be seen that the higher the compressor frequency, the higher the measured T... PTC The higher the windshield, the better the heat dissipation, and the higher the detected T. PTC The lower the temperature, the better.
