Résumé

In this article, an analysis of a condensing unit working with a pair of scroll compressors working in parallel is presented. First the test bench is described. The problems linked to the oil return when using two compressors in parallel at part load are described. The configuration tested was equipped with a special connecting pipe to avoid the use of an oil level regulating system. The tests carried out over the range of the condensing unit are discussed. Emphasis is put on the oil circulation in the refrigerant network at part load when one compressor is cycling.
