An improved method of cooling compressed gases intermediate successive compressive stages in a multi-stage intercooled compressor system without forming condensate is provided. Cooling water flow to an intercooler intermediate successive compressive stages is regulated as a function of the actual temperature of the gas downstream of the intercooler and a set point temperature generated as a function of a linear approximation relating the inlet dew point temperature and the pressure of the gases downstream of the intercooler.

In a multi-stage intercooled compressor system having a plurality of compression stages connected in series with a cooling unit controlled by adjustment means between each stage, an improved method of cooling compressed gases intermediate the stages without forming condensate comprising: measuring the absolute humidity of the gases to be compressed at the suction side of a first compression stage which corresponds to a dew point tTi=aiㆍta+biㆍPi+ci where Pi is the pressure of the compressed gases at the suction side of the successive compression stage designated i, and ai, b1 and Ci are constants; generating a control signal for controlling the cooling of the gases upstream of the compression stage designated i as a function of the set point temperature signal and the actual temperature of the compressed gases at the suction side of the compression stage designated i; and using the control signal to control the adjustment signal to control the adjustment means of the cooling unit which is upstream of the compression stage designated i.
