  • Method of adjusting electronic expansion valve of outdoor unit of air-conditioner
    Patent number: 11604016
    Abstract: Provided is a control method on electronic expansion valve in air conditioner 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; comparing the real-time running frequency of compressor with a first set frequency; if the real-time running frequency is greater than or equal to the first set frequency, obtaining an integral coefficient of the PID algorithm according to a first set rule; if the real-time running frequency is less than the first set frequency, obtaining an integral coefficient of the PID algorithm according to the comparison of the real-time outdoor environment temperature and the first set outdoor environment temperature and a second set rule, or according to the comparison of the real-time outdoor environment temperature and the first set outdoor environment temperature and a third set rule, wherein the selection is based on whether the air conditioner is working in cooling m

  • Method of adjusting electronic expansion valve of air conditioner
    Patent number: 10828965
    Abstract: 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.
