Abstract

PURPOSE: To save energy by maximizing the size of outlet port to a design volume ratio of 1 during starting.
CONSTITUTION: The size of outlet port is maximized at a design volume ratio vi= v1/v2=1 during starting. Where V: volume (volume of rotor screw), 1: primary condition of gas under compressor, 2: final condition of gas under compression. This construction elminates the need of internal compression during starting completely and starting torque as well, thereby saving energy.
