A compressor unit (10) comprises: a compression unit (12) formed by a screw-type compression device for compressing a target gas; a cooler (14); a pre-heater (16); a spill bag unit (33); an adjustment means (31); and a control unit (39a). A suction passage (21) has a first path portion (29a) passing through the pre-heater (16) and a second path portion (29c) not passing through the pre-heater (16). The adjustment means (31) adjusts the flow rate of the target gas flowing through the first path portion (29a) and adjusts the flow rate of the target gas flowing through the second path portion (29c). The control unit (39a) controls the adjustment means (31) so that the suction temperature of the compression unit (12) is within a predetermined temperature range. Therefore, the compressor unit can appropriately manage the temperature of the target gas, which is a boil-off gas suctioned into the screw-type compression unit.
압축기 유닛(10)은 대상 가스를 압축하는 스크루식의 압축 기구에 의해 구성된 압축부(12)와, 쿨러(14)와, 프리히터(16)와, 스필백부(33)와, 조정 수단(31)과, 제어부(39a)를 구비한다. 흡입 유로(21)는 프리히터(16)를 경유하는 제1 경로부(29a) 및 프리히터(16)를 경유하지 않는 제2 경로부(29c)를 갖는다. 조정 수단(31)은 제1 경로부(29a)를 유통하는 대상 가스의 유량을 조정함과 함께 제2 경로부(29c)를 유통하는 대상 가스의 유량을 조정한다. 제어부(39a)는 압축부(12)의 흡입 온도가 미리 정해진 온도 범위 내가 되도록 조정 수단(31)을 제어한다.
