The present invention relates to a compressor unit, a screw compressor, and an operating method of the compressor unit. According to the present invention, the compressor unit (10) comprises: a first compressor (12); a reciprocating second compressor (18) placed on a reliquefaction equipment access flow path (16) branched from a consumer access flow path (14) connected to the first compressor (12); and a control unit (27). The first compressor includes: a screw-type compression unit (22); a bypass flow path (23a) accessing the consumer access flow path (14) and a detention reservoir access flow path (3); and a bypass valve (23b). The control unit (27) increases the treatment volume of the compression unit (22) when starting the second compressor (18) and simultaneously increases the opening degree of the bypass valve (23b) so that the flow rate corresponding to the increased treatment volume can return to the detention reservoir access flow path (3), and starts the second compressor (18) afterwards and simultaneously reduces the opening degree of the bypass valve (23b).

    압축기 유닛(10)은 제1 압축기(12)와, 제1 압축기(12)에 연결되는 수요처 접속 유로(14)로부터 분기하는 재액화 설비 접속 유로(16) 상에 마련된 레시프로식 제2 압축기(18)와, 제어부(27)를 구비한다. 제1 압축기는 스크루식 압축부(22)와, 수요처 접속 유로(14) 및 저류조 접속 유로(3)를 접속하는 바이패스 유로(23a)와, 바이패스 밸브(23b)를 포함한다. 제어부(27)는 제2 압축기(18)의 기동 시에, 압축부(22)의 처리량을 증대시킴과 함께, 증대시킨 처리량에 상당하는 유량이 저류조 접속 유로(3)로 되돌아가도록 바이패스 밸브(23b)의 개방도를 크게 하고, 그 후에 제2 압축기(18)를 기동함과 함께 바이패스 밸브(23b)의 개방도를 작게 한다.
