Optimal Valve Design for Reciprocating Compressor

摘要

We developed a novel discharge valve characters using the stopper to obtain the high efficiency reciprocating compressor for refrigerators. Generally, the sticky force occurred due to the shape of valve, stopper and oil between the valve and valve seat changed the process of valve motion and valve dynamics of compressor. In this paper, we can measure the characteristics of the sticky force and develop the experimental system to measure the time-lag due to the sticky force. Also we optimize the discharge valve motion to minimize the over-compression loss of discharge valve system. We verify the volumetric efficiency of a novel valve system by experiments.
