Air conditioner electronic expansion valve adjusting method, computer device and storage medium

Abstract

The invention discloses an air conditioner electronic expansion valve adjusting method, a computer device and a storage medium. The method comprises the following steps that when a compressor is determined to be in a working state, data of a plurality of actual air exhaust temperature values are acquired within a preset time, the actual air exhaust temperature value newly obtained in the preset time is compared with the target air exhaust temperature value according to the data of the generating data of the plurality of actual air exhaust temperature values, a difference value is generated according to the comparison result, fuzzy reasoning is carried out according to the difference value and the rate, a fuzzy quantity is generated according to the reasoning result, whether a PID output mode is turned into or not is judged, if yes, the fuzzy quantity is converted into a control quantity, and the control quantity is output to control the opening degree of the electronic expansion valve.The invention further provides the computer device and the storage medium for realizing the method. According to the method, the computer device and the storage medium, a variable frequency air conditioning system is capable of being fast and stable, small in air exhaust fluctuation, higher in refrigerating and heating speed, and more energy-saving in operation.

Description

technical field [0001] The invention relates to the technical field of air-conditioning control, in particular to a method for adjusting an air-conditioning electronic expansion valve, a computer device and a storage medium for realizing the method. Background technique [0002] The characteristic of the inverter air conditioner is that it can adjust the operating frequency of the compressor according to the actual indoor environment, set temperature, current, voltage and other related parameters. When setting the temperature, reduce the operating frequency to achieve precise temperature control and avoid hot and cold situations. [0003] With the improvement of the energy efficiency level of air conditioners, more and more energy-efficient inverter air conditioners adopt electronic expansion valve throttling. The adjustment of the opening of the electronic expansion valve is generally based on the comparison between the preset target exhaust temperature and the actual exha...

AI Technical Summary

Problems solved by technology

[0004] However, the problems caused by these adjustment methods are that the period required for system stabilization is long, the fluctuation of exhaust gas is relatively large, and the energy consumption of the inverter air conditioner is relatively large during operation.
