With reference to Figure 2, the present invention electronic expansion valve control method of the embodiment of the 1st, the electronic expansion valve control method comprises:

Step S10, in the air conditioner to enter the low temperature heating mode, obtaining the outdoor ambient temperature;

In a conventional air conditioner in the heating mode the heating temperature is generally higher, the heating temperature range can generally reach up to 17 °C to 30 °C; while the air conditioner is in the low temperature heating mode, the heating temperature relative to the conventional heating mode the heating temperature is low, its heating temperature range are generally 8 °C to 16 °C. Step S10 before, during heating operation and the air conditioner, the outdoor ambient temperature is obtained; in the outdoor ambient temperature is less than or equal to the threshold value of the temperature, control the air conditioner into the low-temperature heating mode. According to the threshold value of the temperature of the air conditioner itself can be the actual conditions of the specific set up, for example can be in the 0 °C to 10 °C in selecting, such as can be set up as 5 °C.

In addition, when the air conditioner and the setting of the mode (such as an air conditioner in the last of the closed mode of operation) is a low-temperature heating mode, the air conditioner when the air conditioner power determined to be entering the low-temperature heating mode, obtaining the outdoor ambient temperature.

Step S20, according to said outdoor ambient temperature control electronic expansion valve operation while preserving the 1st long;

Specific, different outdoor ambient temperature can be the temperature of the a value is set corresponding to the opening of the expansion valve; in addition, the temperature of the outdoor environment is divided into different sections, different section may set a corresponding to the opening of the expansion valve and the like. The electronic expansion valve in the preset time of the opening of the 1st in the outdoor environment along with the reduction of the temperature is decreasing. Therefore, the temperature of the outdoor environment is set corresponding to the pre-set time as the opening of the 1st in a target opening degree of the electronic expansion valve; also to first determine the temperature of the outdoor environment where the interval, the determined interval corresponding to the duration of the open section as the 1st preset in a target opening degree of the electronic expansion valve. In the 1st in preset time, can control the electronic expansion valve to maintain the determined target opening operation.

In addition, can also be in the 1st in the pre-set time, according to the outdoor environment temperature adjustment of the opening of the electronic expansion valve. For example, different outdoor environment temperature can set corresponding to different preset adjustment parameter, to determine the current outdoor environment to control the temperature of the preset adjustment parameter as the current of the electronic expansion valve to adjust the parameter. In the 1st in preset time, can be at a certain time according to the adjusted parameter to the current opening degree of the electronic expansion valve is adjusted.

Step S30, obtaining the compressor current actual exhaust temperature and the target exhaust temperature;

Here, the actual exhaust temperature is present at the temperature of the compressor and the coolant outlet of the real-time the temperature value measured by the sensor. The target exhaust temperature can be pre-set fixed temperature value, by acquiring the prestored in the memory parameter; in addition, the target exhaust temperature can also be based on the current operating state of the air conditioner of the theoretical value of the determined exhaust gas temperature, the air conditioner can obtain the current operation condition of the characterizing parameter (such as the frequency of the compressor, the fan speed and the like), according to the obtained characterization parameter to calculate the target exhaust temperature.

The present target frequency and the opening of the pre-set number of correction parameter combination of relations, can be through numerical comparison or calculation to obtain corresponding the target opening. The present target frequency and opening the correction parameter in the corresponding preset in the mapping relationship as the current of the opening of the target opening.

For example, the establishment of the relationship between the preset corresponding to P can be specific to₀ =(F_X - F_Min ) * (P_Max - P_Min )/(F_Max - F_Min ) + P_Min + P_Correction To carry on the characterization, wherein P₀ For the target opening, F_X As the target frequency F_Min For the minimum frequency of the compressor, P_Max For the maximum opening of the electronic expansion valve, P_Min The electronic expansion valve minimum opening, F_Max For the maximum frequency of the compressor, P_Min The electronic expansion valve minimum opening, P_Correction For opening the correction parameter. Through the present target frequency and the opening degree of the correction parameter into the above characterization in the formula, can be obtained by calculating the target opening.

Wherein in the above-mentioned preset number in the relationship, the opening degree of the correction parameter with the outdoor environment temperature decreases, so that at the same target frequency lower, the target opening with the outdoor ambient temperature decreases. In particular, outdoor environment temperature can pre-divided into (0 °C, 5 °C], (-5 °C, 0 °C], (- ∞, -5 °C] three temperature interval, (0 °C, 5 °C] corresponding to the opening degree of the correction parameter can be in particular to -10, (-5 °C, 0 °C] corresponding to the opening degree of the correction parameter can be in particular to -20, (- ∞, -5 °C] corresponding to the opening degree of the correction parameter can be in particular to -30.
