Abstract
A system and method includes a compressor, a motor drivingly connected to the compressor, a current sensor detecting current supplied to the motor, a discharge line temperature sensor detecting discharge line temperature, and processing circuitry receiving current data from the current sensor and discharge line temperature data from the discharge line temperature sensor and processing the current data and the discharge line temperature data to determine an efficiency of the system.
