Abstract

The fuzzy diagnosis method of air-conditioner refrigerator fault is characterized by that it uses PC machine as core and adopts the fuzzy diagnosis technology to build up fuzzy mapping from element set to remark set of the object to be jadged so as to resolve the fuzzy relationship. For brevity's sake. The present invention provides an example for utilizing PC machine and the fuzzy relationship to obtain the output of the fault signal so as to implement fuzzy diagnosis.

Description

technical field

[0001] The invention relates to a fault diagnosis method for an air conditioner refrigerator. In particular, a fuzzy diagnosis method for identifying faults in air-conditioning refrigerators based on fuzzy mathematics. The invention belongs to the technical fields of mechanical equipment fault diagnosis and refrigeration and air conditioning. Background technique

[0002] The application of air-conditioning and refrigeration has penetrated into all fields of society. The air-conditioning and refrigeration system is becoming more and more complex, the equipment tends to be diversified and large-scale, and the degree of self-control is increasing day by day. The performance of the refrigerator has a great impact on the air conditioning system, and real-time online detection and fault diagnosis of its status are required. At present, in domestic air-conditioning and refrigeration stations, many refrigerators only use a single sensor to monitor absolute paramet...
