Running frequency is made comparisons with the first setpoint frequency.
In the step, the real time execution frequency of compressor refer to compressor start after, acquired according to setting sample frequency
Compressor real time execution frequency.Since the running frequency of compressor is controlled by the controller on air-conditioning computer plate,
Therefore, controller can easily obtain real time execution frequency when compressor is run.And real time exhaust gas temperature refers to compressor
After starting, according to setting sample frequency compressor collected real time exhaust gas temperature, can be by being set in exhaust outlet of compressor
Temperature sensor is set to detect, and real time exhaust gas temperature is obtained by controller.
After getting real time execution frequency, it is made comparisons with the first setpoint frequency, compares the size of the two.Wherein,
First setpoint frequency is the frequency values for presetting and storing in controller of air conditioner, and can be modified by authorization,
It is a threshold frequency for reflecting compressor low-frequency operation Yu non-low-frequency operation.Preferably, the first setpoint frequency is 25-
32Hz, and change with the difference of Air conditioner refrigerating capacity.In general, air conditioner refrigerating amount is bigger, the first setpoint frequency is smaller, on the contrary
?.
Step 12: judging whether real time execution frequency is not more than the first setpoint frequency.If so, executing step 13；If it has not,
Execute step 14.
Step 13: if step 12 determines that real time execution frequency is not more than the first setpoint frequency, determining compressor low frequency fortune

Constant known, being stored in advance.Setting target exhaust temperature is determined according to the linear relationship of compressor real time execution frequency
Degree, can obtain maximum air-conditioning Energy Efficiency Ratio.
When carrying out PID adjusting control to electric expansion valve using the above method, it is not more than in compressor real time execution frequency
The low-frequency operation stage of first setpoint frequency selects lesser integral coefficient as the integral coefficient of pid algorithm, so that low frequency is transported
Adjust regulated value when valve smaller during row, the fluctuation that the fluctuation and valve opening for reducing delivery temperature are adjusted.And in compressor reality
When running frequency be greater than the first setpoint frequency the non-low-frequency operation stage, select biggish integral coefficient as the product of pid algorithm
Divide coefficient, so that regulated value is larger during non-low-frequency operation, adjusts valve speed fast.To, in entire compressor operational process,
Electronic expansion valve opening adjusting is accurate, stablizes, and is conducive to the promotion of air conditioner coolant circulatory system Energy Efficiency Ratio.

Ki is integral coefficient corresponding with real time execution frequency, and A and B are constant.Wherein, the value of f between the first setpoint frequency and
Between second setpoint frequency.It is furthermore preferred that B value is first integral coefficient, when f is the second setpoint frequency, according to Ki=A*f+
The integral coefficient Ki value that B is determined is second integral coefficient.Thus, in entire compressor operational process, integrated in pid algorithm
The value of coefficient is continuous, avoids the fluctuation that valve opening caused by integral coefficient jumps is adjusted.
Moreover, it is excessive or too small to avoid occurring in special circumstances electronic expansion valve opening, it is opened in entire electric expansion valve
