Abstract
A fluid machine and its operating method are provided. The fluid machine (10) includes a main body (1), a screw set (2), a capacity adjustment mechanism (3), an intermediate pressure sensor (5), and a controller (6). The main body (1) includes a low-pressure chamber (11), an intermediate-pressure chamber (12), and a high-pressure chamber (13). The screw set (2) includes a pair of first screws (21) in the low-pressure chamber (11) and a pair of second screws (22) in the high-pressure chamber (13). The capacity adjustment mechanism (4) includes a first slide valve (41) disposed corresponding to the first screws (21) and a second slide valve (42) disposed corresponding to the second screws (22). The intermediate pressure sensor (5) is placed in the intermediate-pressure chamber (12) for obtaining its interior pressure. The controller (6) drives movement of the first slide valve (41) and the second slide valve (42).
