|1. (WO2018006597) METHOD OF ADJUSTING ELECTRONIC EXPANSION VALVE OF AIR-CONDITIONER|
|Applicants:||QINGDAO HAIER AIR CONDITIONER GENERAL CORP., LTD.
|Title:||METHOD OF ADJUSTING ELECTRONIC EXPANSION VALVE OF AIR-CONDITIONER|
Provided is a method of adjusting an electronic expansion valve of an air-conditioner, comprising: obtaining a real-time operating frequency, a real-time exhaust temperature and a real-time outdoor ambient temperature of a compressor; under a cooling working condition, determining to obtain an integration coefficient of a PID algorithm by using a first set rule or a second set rule according to a magnitude relation between the real-time outdoor ambient temperature and a first set outdoor ambient temperature; under a heating working condition, determining to obtain the integration coefficient of the PID algorithm by using the first set rule or a third set rule according to a magnitude relation between the real-time outdoor ambient temperature and a second set outdoor ambient temperature; and regarding a difference value between the real-time exhaust temperature and a set target exhaust temperature as a deviation value, performing a PID control on the opening degree of the electronic expansion valve based on the deviation value. The method realizes accurate, stable adjustment to the opening degree of the electronic expansion valve.
