Embodiment Construction

[0053] according to figure 2 In the illustrated embodiment, an industrial appliance E of the refrigeration compressor type is associated with a system S for tracking the performance of the industrial appliance according to the invention.

[0054] A refrigeration compressor with a suction pressure P in A gas is obtained as input, and the gas is compressed to obtain a discharge pressure P greater than the suction pressure out gas as output.

[0055] The gas temperature is T g .

[0056] The compressor is also composed of especially water temperature T w coolant to be further cooled. The compressor consumes electrical energy, characterized by the consumed power W, in order to perform the compression.

[0057] The system S comprises a measuring device 2 located on the appliance E for obtaining measurements. The memory device 3 is used to record corresponding data, in particular in the form of hourly averages.

[0058] Said measurements include in particular measurements o...

Abstract

The method involves measuring a set of operating parameters and power consumption of a compressor, and calculating an estimation of power consumption by using a predetermined model. The measured power consumption value and the estimated value are compared to obtain an overconsumption value and an overconsumption score. An alarm is triggered if a probability of overconsumption exceeds an overconsumption probability threshold. An independent claim is also included for a system allowing implementing a method for monitoring performance of a compressor.

Description

technical field [0001] The present invention relates to a method of tracking the performance of an industrial appliance, and an apparatus for implementing said method. [0002] The invention has particular application to air components separation units using at least air, oxygen or nitrogen compressors. Background technique [0003] Performance tracking of industrial appliances, especially compressors, is used to plan maintenance of compressors and monitor their efficiency, and to steer operational choices towards best performing appliances. [0004] It is desirable for the operator of the industrial appliance to have an indicator of the appliance's performance with which to reliably detect any degradation of the appliance. [0005] Thus, the indicator should make it possible to distinguish between a degradation of the state of the industrial appliance and a simple change in operating conditions. [0006] To this end, document FR 2 837 598 filed by the applicant describes ...
