PURPOSE: A refrigerant feed device and an operation method thereof are provided to make each drive unit directly coupled with each output shaft, thereby implementing a coupling wherein the output shafts are not capable of being rotated relatively. CONSTITUTION: A refrigerant feed device includes a refrigerant pump(2). The refrigerant pump is capable of being driven through a planetary gear(5) by a first drive unit(6) and a second drive unit. The planetary gear comprises a first input shaft(7) corresponding to a first drive unit and a second input shaft(8) corresponding to a second driver unit. A coupling(22) makes input shafts directly to be coupled with each other in at least one operation mode. |
