Beschreibung
Zusammenfassung:	Provided is a control method on electronic expansion valve in air conditioner, which comprises: obtaining a real-time running frequency of compressor, a real-time exhaust temperature and a real-time outdoor environment temperature as the compressor running; if the air conditioner working in cooling mode, using a first set rule or a second set rule to obtain an integral coefficient in which the selection is based on the comparison of the real-time outdoor environment temperature and a first set outdoor environment temperature; if the air conditioner working in heating mode, using a first set rule or a third set rule to obtain an integral coefficient in which the selection is based on the comparison of the real-time outdoor environment temperature and a second set outdoor environment temperature; performing a PID control on the electronic expansion valve by using an error of the difference between real-time exhaust temperature and a set target exhaust temperature. The method realizes an accurate and stable control on opening amount of electronic expansion valve in air conditioner.
