Abstract: The compressor according to the compressor includes a sealed enclosure containing a compression stage, an electric motor having a stator provided with a first and second end windings, an intermediate casing surrounding the stator so as to define an annular outer volume with the sealed enclosure, connecting means arranged to fluidly connect the compression stage and a distal chamber defined by the intermediate casing and the electric motor and comprising the second end winding, and a refrigerant suction inlet emerging in the annular outer volume. The connecting means include at least one refrigerant circulation duct situated outside the intermediate casing, and at least one distal window formed on the intermediate casing and emerging on the one hand in the at least one refrigerant circulation duct and on the other hand in the distal chamber near the second end winding of the stator.

Abstract: This scroll compressor includes first and second fixed scroll members, first and second orbiting scroll members, a first Oldham coupling provided between the first orbiting scroll member and the first fixed scroll member and configured to prevent rotation of the first orbiting scroll member with respect to the first fixed scroll member, and a second Oldham coupling provided between the second orbiting scroll member and the second fixed scroll member and configured to prevent rotation of the second orbiting scroll member with respect to the second fixed scroll member. The first Oldham coupling is slidably mounted with respect to the first fixed scroll member along a first displacement direction, and the second Oldham coupling is slidably mounted with respect to the second fixed scroll member along a second displacement direction parallel with respect to first displacement direction. First and second orbiting scroll members are configured to operate in phase opposition.

Abstract: A method for managing oil in a running multi-compressor refrigeration system including a controller and a multi-compressor device, includes monitoring an oil level in the oil sump of each compressor through the respective oil level detection device; detecting that a lack of oil situation occurs in a running compressor, if the oil level in said running compressor reaches a predetermined threshold condition; performing an oil managing action if a lack of oil situation is detected for a running compressor, the oil managing action being based on a changing of ON/OFF configurations of the compressors in the multi-compressor device and including performing an oil balancing action, if more than a half of the total number of compressors are running, or performing an oil returning action, if a half or less of the total number of compressors are running.
