Abstract

PURPOSE: To ensure oil return to the operating compressor by a method wherein oil return line is installed to each compressor from the second gas-liquid separator installed between the first gas-liquid separator and compressor, and making the resistance of oil pipe passage to decrease in the order to accord with the resistance of gas suction tube.
CONSTITUTION: When the compressor 2 stops, oil accumulated to the lower side of the suction header 5 is returned to the compression element chamber 1d, by the pressure difference between compression element chamber 1d of the operating side compressor 1 and the suction header 5 which constitutes the second gas-liquid separator and gravity. On the other hand, oil flown into the oil return tube 7 of the compressor 2 which is connected to the up stream side of the suction header 5 flows into the compression element chamber 2d, however, the oil exceeding the requirement of the compressor 2 is supplied to the compression element chamber 1d of the operating compressor 1 through oil balancing pipe 10, because of the pressure difference between compression element chamber 1d, and compression element chamber 2d. This arrangement allows to separate oil from the gas suctioned to compressor and return gas only the motor chamber separating oil, and ensure to return oil to the compression element chamber of the operating compressor.
