Fast on-line quality control of refrigerators based on thermal image detection and power consumption.

Author(s) : CRISTALLI C., GRASSI A. de, RODRIGUEZ R. M.

Summary

The aim of the paper was to design an automatic on line system, based on thermal imaging of the condenser and the compressor, for detection of faulty refrigerators. With the thermal image approach it is possible to reduce the on-line test time to below 8 minutes instead of 30-90 minutes, assuring an even higher level of accuracy. This is an effective and non-contact method that provides a quick thermal evaluation feasible for a 100% on-line quality control of refrigerators. The data collected are analysed and the classification, i.e. satisfactory or defective refrigerators, is automatically performed without an operator.
