Abstract
At start up, at least one bank of cylinders of a compressor is allowed to compress gas and deliver the compressed gas to the system while at least the majority of the other banks are subject to hot gas bypass. The entire compressor is subject to suction modulation such that the amount of gas that can be compressed and delivered by all of the operating banks can be controlled and thereby the compressor power demand is controlled.
