Field reliability improvement methodology of home air-conditioning parts driven by service failure data
In order to make full use of the abundant data reflecting the field reliability of air-conditioning components contained in the after-sales service information,an impro-ving field reliability methodology driven by service fault data and applying FMEA is pro-posed.Firstly,the relevant standards,processes and data processing methods of mining service fault data are given.Secondly,the field failure rates of components based on service failure data are estimated,and then the object component of field reliability im-provement is determined.Finally,a certain type of home wall-mounted air conditioner is used as an application study case.Based on the estimated results of component service fail-ure rate,the outdoor electronic control board is determined as the improvement object,and the complete process of applying FMEA to improve its field reliability is given.This methodology can effectively guide the field reliability improvement of air conditioners.Be-cause of its generality,it also has reference for improving the field reliability of household appliances such as refrigerators,washing machines and water heaters.
