Abstract

The invention provides a compressor fault diagnosis apparatus, method and system and compressor equipment. A compressor fault diagnostic apparatus including a current sensing unit to sense a current flowing through a motor of the compressor, a fault diagnostic unit to determine whether or not the motor performs a reverse rotation based on the current flowing through the motor, and a cut-off unit to remove power based on a determination of the fault diagnostic unit. The invention can control the compressor to run so as to improve the running reliability of the compressor.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Application No. 10-2019-0004130 filed January 11, 2019, the entire contents of which are hereby incorporated by reference as if fully set forth herein. technical field [0003] The present disclosure relates to a compressor fault diagnosis device and system and a diagnosis method thereof, and compressor equipment, the diagnosis device and the diagnosis method thereof are capable of determining whether a compressor rotates in reverse due to a momentary power failure. Background technique [0004] Generally speaking, a compressor is a device that converts mechanical energy into compression energy of a compressible fluid, which can be used as part of a refrigeration device (eg, a refrigerator or an air conditioner). [0005] Compressors are mainly divided into reciprocating compressors, rotary compressors and scroll compressors. In the reciprocating compressor, a compression s...
