Abstract
A method for optimizing the operating efficiency of a compressor having a compression module for compressing a fluid, the compression module including an inlet for receiving the fluid and an outlet for discharging compressed fluid, the compressor including a prime mover for driving the compression module and a rotatable fan for drawing ambient air into the compressor. The compressor includes a first temperature sensor for sensing the temperature of compressed fluid discharged from the compression module, a second temperature sensor for sensing the temperature of a coolant circulating through the prime mover, a third temperature sensor for sensing the temperature of the fluid entering the compression module, and a fourth temperature sensor for sensing the temperature of a lubricant mixed with the fluid as the fluid is compressed in the compression module. The compressor includes an electronic control module (ECM) electrically connected to the four temperature sensors for receiving signals therefrom. The ECM includes a non-volatile memory containing empirical data relating to optimal operating set points of the compressor and a logic routine for controlling the rotational speed of th…
