PROBLEM TO BE SOLVED: To provide a compressor apparatus which operates stably without response delay and unnecessary power consumption, by automatically adjusting a set target value of a discharge pressure thereof according to a terminal pressure or the like of a compressed gas operating equipment; and a method of controlling the compressor apparatus. SOLUTION: In the compressor apparatus, the terminal pressure is detected by a pressure detector 32 provided at a gas header 8 connected to a compressed gas operating equipment 9. A pressure loss between a compressed gas discharge outlet and the compressed gas operating equipment 9 in the compressor apparatus is calculated based on the detected terminal pressure and a detected value of a compressed gas discharge pressure. A target discharge pressure is calculated from the calculated pressure loss and a predetermined terminal pressure set target value. The calculated target discharge pressure is used as a new set target value of the discharge pressure for controlling a capacity of the compressor apparatus. COPYRIGHT: (C)2009,JPO&INPIT
