Abstract
A method for monitoring compressor performance in a refrigeration system includes calculating an isentropic efficiency of a compressor of the refrigeration system, averaging isentropic efficiency over a predetermined period, comparing the average to an efficiency threshold, and detecting a compressor malfunction based on the comparison. The method may be executed by a controller or stored in a computer-readable medium.
