Abstract

This compressor system is provided with: a driving machine having a rotary-driven first output shaft and a second shaft that is rotary driven so as to reach the same speed as the first output shaft; a working-fluid-compressing first compressor to which the rotation of the first output shaft is transmitted; a working-fluid-compressing second compressor to which the rotation of the second output shaft is transmitted; a variable-speed step-up gear for increasing the speed of the first output shaft and transmitting the increased speed to the first compressor, said step-up gear being capable of varying the increased speed; and a constant-speed step-up gear for increasing the speed of the second output shaft and transmitting the increased speed to the second compressor, said step-up gear keeping the increased speed constant.

Claims5

Dependent claims

A compressor system comprising:

a driving machine having a first output shaft that is rotatably driven, and a second output shaft that is rotatably driven to have the same rotational speed as the first output shaft;
a first compressor configured to receive rotation of the first output shaft and compress a working fluid;
a second compressor configured to receive rotation of the second output shaft and compress a working fluid;
a variable speed step-up gear configured to increase the rotational speed of the first output shaft to transmit the rotational speed to the first compressor and vary the increased rotational speed;
and
a constant speed step-up gear configured to increase the rotational speed of the second output shaft to transmit the rotational speed to the second compressor and cause the increased rotational speed to be constant,
wherein the first output shaft is disposed coaxially with the second output shaft and is disposed at an opposite side to the second output shaft with driving machine interposed therebetween.
