If the air conditioner is controlled to heat when the indoor temperature is low and the insulation effect is poor, it may cause the air conditioner to frequently control to prevent cold air from blowing out, which in turn causes the air volume blown out by the indoor unit and the frequency of the compressor in the outdoor unit to fluctuate frequently (for example, switching from high air volume to low air volume, and from high frequency to low frequency), ultimately affecting the heating effect of the air conditioner and the user experience.

Detailed Implementation

[0045] Some embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0046] In the description of this invention, "processor" can include hardware, software, or a combination of both. A processor can be a central processing unit, a microprocessor, a digital signal processor, or any other suitable processor. The processor has data and / or signal processing capabilities. The processor can be implemented in software, in hardware, or a combination of both. Non-transitory computer-readable storage media includes any suitable medium capable of storing program code, such as magnetic disks, hard disks, optical disks, flash memory, read-only memory, random access memory, etc.

[0047] See appendix Figure 1 , Figure 1 This is a schematic flowchart illustrating the main steps of an air conditioning anti-cold air control method according to an embodiment of the present invention. Figure 1 As shown, in this embodiment of the invention, when the air conditioner is powered on or defrosting is complete and requires anti-cold air control, the air conditioner can be controlled to prevent cold air through the following steps S101 to S108:

[0048] Step S101: Control the indoor unit fan to operate in low fan speed mode and according to the frequency limiting coefficient c corresponding to low fan speed mode. l The target operating frequency of the compressor is corrected.

[0049] The indoor unit fan has three operating modes: low wind mode, medium wind mode, and high wind mode. Low wind mode is the operating mode in which the fan speed is less than or equal to the preset lower limit of wind speed. High wind mode is the operating mode in which the fan speed is greater than or equal to the preset upper limit of wind speed. Medium wind mode is the operating mode in which the fan speed is greater than the preset lower limit of wind speed but less than the preset upper limit of wind speed.

[0050] Low, medium, and high fan speed modes each correspond to different frequency limiting coefficients for the compressor's target operating frequency. The frequency limiting coefficients c for low, medium, and high fan speed modes are also specified. l c m and c h The size relationship is 0 <c l <c m <c h ≤1.

[0051] Based on the frequency limiting coefficient c corresponding to the low wind mode l When correcting the target operating frequency of the compressor, the frequency limiting coefficient c can be used. l The product of the target operating frequency and the target operating frequency is used as the corrected target operating frequency, and the compressor is controlled to operate at the corrected target operating frequency.

[0052] Step S102: Based on the temperature T of the indoor unit heat exchanger m Determine if the triggering conditions for stroke mode are met; if so, proceed to step S103; if not, proceed to step S101, continue controlling the indoor unit fan to operate in low-wind mode and according to the frequency limiting coefficient c corresponding to low-wind mode. l The target operating frequency of the compressor is corrected.

[0053] Step S103: Control the indoor unit fan to operate in medium-wind mode and according to the frequency limiting coefficient c corresponding to medium-wind mode. m The target operating frequency of the compressor is corrected.

[0054] Based on the frequency limiting coefficient c corresponding to the stroke mode m When correcting the target operating frequency of the compressor, the frequency limiting coefficient c can be used. m The product of the target operating frequency and the target operating frequency is used as the corrected target operating frequency, and the compressor is controlled to operate at the corrected target operating frequency.

[0055] Step S104: Based on the temperature T of the indoor unit heat exchanger mDetermine whether the triggering conditions for the high wind mode are met; if they are met, proceed to step S105; if not, increment the loop count N by 1 and proceed to step S101.

[0056] In this embodiment of the invention, when the anti-cold air control is started, the number of cycles N is initialized first by setting the number of cycles N to zero, that is, the initial value of the number of cycles N is zero.

[0057] Step S105: Control the indoor unit fan to operate in high-speed mode and according to the frequency limiting coefficient c corresponding to high-speed mode. h The target operating frequency of the compressor is corrected.

[0058] Based on the frequency limiting coefficient c corresponding to the high wind mode h When correcting the target operating frequency of the compressor, the frequency limiting coefficient c can be used. h The product of the target operating frequency and the target operating frequency is used as the corrected target operating frequency, and the compressor is controlled to operate at the corrected target operating frequency.

[0059] Step S106: Based on the temperature T of the indoor unit heat exchanger m Determine if the trigger condition for stopping the anti-cold air control is met; if it is, proceed to step S107; if not, increment the loop count N by 1 and proceed to step S103 to continue controlling the indoor unit fan to operate in medium-wind mode and according to the frequency limiting coefficient c corresponding to medium-wind mode. m The target operating frequency of the compressor is corrected.

[0060] Step S107: Determine whether the number of loops N is less than or equal to the set value;

[0061] If the value is less than or equal to the set value, proceed to step S108 and stop the anti-cold air control.

[0062] If the value is greater than the set value, the number of cycles N is set to zero and the process proceeds to step S101, that is, the number of cycles N is re-initialized, and then the process proceeds to step S101 to continue the next round of anti-cold air control.

[0063] Step S108: Stop the anti-cold air control.

[0064] Based on the method described in steps S101 to S108 above, the operating mode of the indoor unit fan (low wind mode, medium wind mode and high wind mode) and the target operating frequency of the compressor can be switched by different trigger conditions. When the trigger condition for stopping the anti-cold air control is met and the number of cycles N is less than or equal to the set value, the anti-cold air control is stopped, thereby preventing the air conditioner from frequently performing anti-cold air control, which would cause fluctuations in the air conditioner's power and affect the air conditioner's heating effect.

[0065] The triggering conditions for the stroke mode, the high wind mode, and the triggering conditions for stopping the anti-cold wind control in the embodiments of the present invention will be explained below.

[0066] The trigger condition for stroke mode is the temperature T of the indoor unit's heat exchanger. m The temperature is greater than the preset stroke triggering temperature threshold T. th1 The high-wind mode is triggered by a temperature T. m Temperature greater than the preset high wind triggering temperature threshold T th2 The trigger condition for stopping the anti-cold air control is temperature T. m The temperature exceeds the preset trigger temperature threshold T for stopping the anti-cold air control. th3 , among which, T th1 <T th2 <T th3 .

[0067] See appendix Figure 2 In some implementations, in order to accurately determine the trigger temperature threshold T th1 T th2 and T th3 The specific value can be determined through the following steps S201 to S202 to prevent the air conditioner from frequently controlling the cold air, so that the above steps S101 to S108 can be used to prevent the air conditioner from frequently controlling the cold air.

[0068] Step S201: Based on the indoor ambient temperature T of the room where the air conditioner is located c Determine the temperature threshold compensation amount ΔT.

[0069] Temperature threshold compensation ΔT and indoor ambient temperature T c There is a positive correlation, that is, the indoor ambient temperature T c The higher the temperature threshold, the greater the temperature compensation ΔT. (Indoor ambient temperature T) c The lower the temperature threshold, the smaller the temperature threshold compensation amount ΔT.

[0070] In some implementations, the indoor ambient temperature T can be... c With the preset indoor temperature threshold T cth Compare;

[0071] If T c >T cth Then the temperature threshold compensation amount ΔT = 0;

[0072] If T c ≤T cth Then, the temperature threshold compensation amount ΔT = -d, where d represents a preset constant and d > 0. Those skilled in the art can flexibly set the specific value of the constant d according to actual needs; for example, in some embodiments, d = 5℃.

[0073] Step S202: Determine the stroke triggering temperature threshold T based on the temperature threshold compensation amount ΔT and the following formula (1). th1 High wind triggering temperature threshold T th2 and the trigger temperature threshold T for stopping anti-cold air control th3 .

[0074]

[0075] The parameter T in formula (1) base1 T base2 and T base3 T represents the preset base threshold for the mid-wind trigger temperature, the preset base threshold for the high-wind trigger temperature, and the preset base threshold for the trigger temperature to stop the anti-cold air control, respectively. base1 <T base2 <T base3 .

[0076] Those skilled in the art can flexibly set the basic threshold T according to actual needs. base1 T base2 and T base3 The specific value, for example, in some implementations, T base1 =25℃, T base2 =30℃, T base3 =35℃.

[0077] By using the methods described in steps S201 to S202 above, the trigger temperature threshold T can be accurately determined. th1 T th2 and T th3 The specific values ​​are used to switch the indoor unit fan's operating mode (low wind mode, medium wind mode, and high wind mode) and the compressor's target operating frequency through different trigger conditions, and to stop the anti-cold air control when the trigger conditions for stopping the anti-cold air control are met, thus preventing the air conditioner from frequently performing anti-cold air control.

[0078] Further reading is available in the appendix. Figure 1 In some other embodiments of the air conditioning anti-cold air control method according to the present invention, step S107 in the foregoing method embodiments is replaced by the following steps S1071 to S1073.

[0079] Step S1071: Determine whether the number of loops N is less than or equal to the set value;

[0080] If the value is less than or equal to the set value, proceed to step S108 and stop the anti-cold air control.

[0081] If the value exceeds the set value, it indicates that the air conditioner cannot complete the anti-cold air control within a short time. Therefore, the operating time of the indoor unit fan in low, medium, and high fan modes can be extended. In this embodiment, this can be addressed by increasing the aforementioned trigger temperature threshold T. th1 T th2 and T th3 This can be done to extend the aforementioned running time. Specifically, the process can proceed to step S1072, where the aforementioned trigger temperature threshold T is adjusted. th1 T th2 and T th3 Make corrections and increase the aforementioned trigger temperature threshold T. th1 T th2 and T th3 .

[0082] Step S1072: Based on the number of cycles N and using the following formula (2), the stroke trigger temperature threshold T is determined. th1 High wind triggering temperature threshold T th2 and the trigger temperature threshold T for stopping anti-cold air control th3 Make corrections.

[0083]

[0084] The parameter T′ in formula (2) th1 、T′ th2 and T′ th3 These represent the corrected wind trigger temperature threshold, the corrected high wind trigger temperature threshold, and the corrected trigger temperature threshold for stopping anti-cold air control, respectively, where T′ th1 <T′ th2 <T′ th3 .

[0085] If the trigger temperature threshold T for stopping the anti-cold air control is... th3 The setting is relatively high, with an indoor ambient temperature T c The trigger temperature threshold T cannot be reached for an extended period of time. th3 This would cause the air conditioner to continuously operate under anti-cold air control, resulting in a heavy load and affecting its normal operation. To address this, in some implementations, the corrected trigger temperature threshold T′ for stopping anti-cold air control is calculated using the above formula (2). th3 Afterwards, it is also possible to determine the trigger temperature threshold T′ of the corrected stop anti-cold air control. th3 Is it greater than the preset upper limit? If it is greater than the preset upper limit, then the corrected trigger temperature threshold T′ for stopping the anti-cold air control will be set. th3 Set to the upper limit value to avoid the above-mentioned problem; if it is less than or equal to the preset upper limit value, maintain the corrected trigger temperature threshold T′ for stopping the anti-cold air control. th3 constant.

[0086] Step S1073: Set the number of cycles N to zero and proceed to step S101.

[0087] By using the methods described in steps S1071 to S1073 above, the air conditioner can more reliably perform anti-cold air control and avoid the air conditioner frequently performing anti-cold air control.
