The invention discloses an electronic expansion valve control method and device, electronic equipment, a medium and a product. The method comprises the steps that the deviation delta T between the current actual supercooling degree and the target supercooling degree is calculated; if the delta T is larger than the first threshold value, the step number delta EXV1, needing to be adjusted, of the electronic expansion valve is obtained through calculation according to the formula P * delta T + I * delta T * delta T; selecting a proper gradient to process and output a first target electronic expansion valve step number; judging whether the compressor speed is less than a preset speed; if the rotating speed of the compressor is smaller than the preset rotating speed, an exhaust pressure protection threshold value P1 is set; the deviation delta P between the current actual exhaust pressure and the P1 is calculated; and if the delta P is not smaller than or equal to the second threshold value, selecting a scaling factor P and an integral factor I, and calculating the step number delta EXV2 of the electronic expansion valve needing to be adjusted through a formula P * delta P + I * delta P * delta P. The heat pump air conditioning system can be in an efficient and stable operation state all the time.

    本申请公开了一种电子膨胀阀控制方法、装置、电子设备、介质及产品,该方法包括:计算当前实际过冷度和目标过冷度的偏差ΔT;如果|ΔT|大于第一阈值,通过公式P*ΔT+I*|ΔT|*ΔT计算得到电子膨胀阀需调节的步数ΔEXV1;选取合适梯度处理输出第一目标电子膨胀阀步数;判断压缩机转速是否小于预设转速;如果压缩机转速是小于所述预设转速,则设定排气压力保护阈值P1;计算当前实际排气压力和P1的偏差ΔP;如果|ΔP|不是小于等于第二阈值,则选取比例因子P和积分因子I,通过公式P*ΔP+I*|ΔP|*ΔP计算需要调节的电子膨胀阀步数ΔEXV2。本申请能实现让热泵空调系统始终处于高效稳定的运行状态。
