SUMMARY A system includes a compressor operable in a refrigeration circuit and including a motor, a current sensor providing a high-side signal indicative of an operating condition of a high-pressure side of the refrigeration circuit, a discharge line temperature sensor providing a low-side signal indicative of an operating condition of a low-pressure side of the refrigeration circuit, and processing circuitry processing the high-side signal and the low-side signal to indirectly determine a non-measured operating parameter of the refrigeration circuit.
FIG. 31 shows that the discharge line temperature can be used in conjunction with the ambient temperature sensor to provide an installer with an additional diagnostic tool. Specifically, particular temperature differences (i.e., discharge line temperature�ambient temperature) relate to specific fault conditions. Therefore, this temperature difference is useful to the installer in properly diagnosing the compressor 10 and system 11.
