and step S100, acquiring the operation data of the air conditioner.
In step S100, after the air conditioner is started to operate, the air conditioner system is detected every a period of time Δ t (about 1-3 min), and the operation data of the air conditioner is obtained. The operation data of the air conditioner may include operating condition data, operation state data of the air conditioner, and the like, wherein the operating condition data may be environmental parameter data and the like, the operation state data may be operation parameter data such as a frequency of a compressor, a valve step of an expansion valve, and the like, and may also be energy efficiency parameter data such as an exhaust temperature, power, a power supply voltage, a power supply frequency, and the like. Whether the air conditioner is stable or not can be determined through the operation data of the air conditioner.
And step S200, acquiring the current running capacity of the air conditioner.
In step S200, after the air conditioner is started and operated, the air conditioner system is detected once every a period of time Δ t (about 1-3 min) to obtain the current operation capability of the air conditioner, wherein the current capability is represented by Φ At present Indicating, recording the current capability Φ At present . In this embodiment, it may be considered that the operation data and the current capacity of the air conditioner are obtained by detecting the air conditioner system at intervals of Δ t. In some embodiments, the current capability may also be considered as a kind of operation data, and the operation data required for debugging is detected at intervals of Δ t.
And step S300, judging whether the air conditioner is stable or not according to the operation data and the current capacity.
It should be noted that, if the operation data and the current capacity meet the respective corresponding stability conditions within the set time period, the air conditioner may be considered to be stable. If the air conditioner is stable, the step S400 is performed. And if the air conditioner is unstable, assigning the current capacity detected this time to the last capacity, returning to continuously execute the step S100 and the step S200, and continuously detecting the air conditioner system at intervals of a period of time delta t to obtain the operation data and the current capacity. It should be noted that the last capability represents the capability obtained in the last detection, and Φ is used for Last time It is shown that the last time capability can be regarded as a variable, which is assigned by the current capability obtained by the last test.
And step S400, judging whether the frequency of the compressor of the air conditioner fluctuates according to the fluctuation condition of the current capacity relative to the preset capacity interval.
In step S400, the lower limit of the preset capacity interval is the capacity lower limit, and the upper limit is the sum of the capacity lower limit and the preset capacity constant. Wherein the lower limit of the capacity is represented by Lower limit of The setting can be carried out manually according to different models and different test items. Preparation ofThe capacity constant is represented by Δ Φ, and the value range of Δ Φ may be (20W to 50W). Therefore, the predetermined capacity interval is (Φ) Lower limit of ，Φ Lower limit of +ΔΦ)。
In order to improve the accuracy of judging the frequency fluctuation condition and ensure that the current capacity of the air conditioner meets the minimum capacity requirement, the current capacity can be adjusted by adjusting the frequency, and the purpose of adjusting the frequency is to ensure that the current capacity is in a preset capacity interval. Therefore, referring to fig. 4, fig. 4 is a flowchart illustrating the sub-steps of step S400 of the automatic air conditioner APF debugging method shown in fig. 3; step S400 may include the following sub-steps 410 to 440.
And a substep S410, if the current capacity is larger than the sum of the capacity lower limit and a preset capacity constant, controlling the frequency of the compressor to be reduced by a frequency regulation amplitude, and assigning the current capacity to the last capacity.
In the sub-step S410, the sum of the lower limit of the capability and the preset capability constant is the upper limit of the preset capability interval, and if Φ is At present ＞Φ Lower limit of + Δ Φ, the current capacity may be considered to be larger than the upper limit of the preset capacity interval, and at this time, the current capacity needs to be decreased, and the frequency of the compressor may be controlled to decrease by a frequency adjustment amplitude, where the frequency adjustment amplitude is represented by Δ F. And assigning the current capability to the last capability, i.e. assigning Φ At present ＝Φ Last time For subsequent comparison. Through the control, the current capability is restored to the preset capability interval again.
And a substep S420 of controlling the frequency of the compressor to increase by a frequency adjustment amplitude and assigning the current capacity to the last capacity if the current capacity is less than the capacity lower limit.
In sub-step S420, the lower limit of the capability is the lower limit of the predetermined capability interval, if Φ At present ＜Φ Lower limit of If the current capacity is considered to be smaller than the lower limit value of the preset capacity interval, the current capacity needs to be increased, and the frequency of the compressor can be controlled to increase in the frequency adjustment range. And assigning the current capability to the last capability, i.e. assigning Φ At present ＝Φ Last time For subsequent comparison. Through the control, the current capability is restored to the preset capability interval again.
It should be noted that the frequency adjustment amplitude in the sub-steps S410 and S420 is a variation of the frequency adjustment, which is calculated according to the target capacity, the current capacity and the current frequency of the compressor. The frequency adjustment amplitude is calculated by the following formula:
Figure BDA0003311277020000111
where Δ F denotes the frequency adjustment amplitude, Φ Target Representing the target capability,. phi At present Indicating the current capability, F At present Indicating the current frequency of the compressor.
That is, in order to adjust the current capability to the target capability, so that the current capability is maintained within the preset capability interval, the current frequency may be changed by the frequency adjustment amplitude, wherein the target capability may be selected as Φ Lower limit of +20W。
And a substep S430, if the current capability is larger than the product of the capability lower limit and the capability coefficient and the last capability is smaller than the capability lower limit, adding one to the fluctuation times.
In the substep S430, if the previous capability is smaller than the lower limit of the capability, it may be considered that the previous capability jumps out of the preset capability interval and is below the lower limit of the preset capability interval; and the current capability is larger than the product of the capability lower limit and the capability coefficient, and the current capability can be considered to return to the preset capability interval from the lower limit value of the last time. Optionally, the capability coefficient μ is greater than 1, and may be set according to actual needs, for example, 1.002 to 1.008 may be selected. Thus, the value of the capacity coefficient is a small value larger than 1, and the current capacity larger than the product of the capacity lower limit and the capacity coefficient indicates that the current capacity is larger than the capacity lower limit by a small value, that is, the current capacity is considered to fluctuate once relative to the last capacity, so that the fluctuation times are increased by one. Therefore, the accuracy of the fluctuation judgment can be effectively improved. Therefore, if Φ At present ＞(Φ Lower limit of Mu) and phi Last time ＜Φ Lower limit of The number of fluctuations WaveTimes is increased by 1 time.
And a substep S440, if the fluctuation frequency is greater than the preset frequency, determining that the frequency of the compressor fluctuates.
In the sub-step S440, the preset number of times may be set according to actual needs, and the preset number of times may be 2 times in this embodiment. If the fluctuation times WaveTimes is larger than 2, judging the condition that the frequency fluctuates, and improving the accuracy of frequency fluctuation judgment. Of course, the preset number of times may be 3 times, 4 times, etc.
Referring to fig. 3, after determining that the frequency fluctuates, in order to avoid the situation that the capacity is unstable due to the frequency fluctuation and the data cannot be stored, the method for automatically debugging the APF of the air conditioner according to the embodiment may further include step S500.
Step S500, if the frequency of the compressor fluctuates and the current capacity is larger than the upper limit value of the preset capacity interval, controlling the frequency of the compressor to be unchanged.
In step S500, if the frequency fluctuates and the current capacity is greater than the upper limit of the preset capacity interval, and the frequency fluctuation range Δ F is less than 0, the compressor frequency is controlled to be unchanged. Note that frequency fluctuation occurs and phi At present ＞Φ Lower limit of + Δ Φ, if the frequency adjustment of substep S410 is still followed, the frequency will decrease, which may occur At present ＜Φ Lower limit of The situation of (2) continues to fluctuate. Therefore, the embodiment occurs in the frequency fluctuation condition in step S500 and phi At present ＞Φ Lower limit of At + Δ Φ, the frequency of the compressor is controlled to be unchanged, that is, even if the current capacity is greater than the upper limit value of the preset capacity interval, the frequency is kept unchanged without performing the down-conversion process. Therefore, the capacity of the air conditioner can meet the minimum capacity requirement of a test project, and meanwhile, the conditions that the capacity is unstable due to frequency fluctuation and data cannot be stored are avoided, wherein the frequency is the lowest and the APF is the highest.
In order to execute the corresponding steps in the above-mentioned embodiments and various possible embodiments, an implementation of the automatic commissioning apparatus 200 for the air conditioner APF is given below. Fig. 5 is a schematic functional block diagram of an automatic debugging apparatus 200 for an air conditioner APF according to an embodiment of the present invention.
