<p><P>PROBLEM TO BE SOLVED: To suppress oil deviation, that is, refrigerator oil deviating to a specific compressor, to restrain the occurrence of a lubrication failure in the other compressor that runs short of refrigerator oil in a refrigerating apparatus provided with a compression mechanism having a plurality of compressors connected in parallel with each other. <P>SOLUTION: A discharge pipe 56a of the first compressor 14a and a discharge pipe 56b of the second compressor 14b are provided with oil separators 37a, 37b, respectively. An oil return passage 32 for returning the refrigerator oil from the oil separators 37a, 37b to the compression mechanism 40 is constituted to unite the refrigerator oil separated by the respective oil separators 37a, 37b and to distribute the united refrigerator oil to the first compressor 14a and the second compressor 14b. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
