Study of Dynamic Characteristics of Cylinder Profile of Rotary Vane Compressor for Automotive Air Conditioner

Cylinder Profile is one of the key factors influencing the performance of rotary vane compressor used for automobile air conditioning system. A new type of cylinder profile is put forward in the paper, which is composed of three parts: circle arc near the minor axis of cylinder profile, main curve and transit curve between them. Volume ratio of the compressor, motion of vane, forces and moments acting on the rotor are studied with some typical cylinder profiles. It is shown that the profile composed of trigonometric function has better velocity and acceleration characteristics than other profiles mentioned in the paper. Stress under impact and noise pollution of the compressor could be reduced effectively by optimization design of the transit curve. Cylinder profile has little influence on shaft power of rotary vane compressor
