Abstract
An economizer is connected to a fluid line connecting the first and second stages of a compressor at a point downstream of the bypass for unloading the first stage. The economizer flow controls the discharge temperature of the second stage and, in addition, coacts with the bypassing of the first stage such that all of the flow supplied to the second stage is at system suction pressure when the bypass is fully open.
