A study of flapper valve motion in a variable speed compressor.

Number: pap. n. C3, 1343

Author(s) : LENZ J. R., COLLINGS D.

Summary

This study is an attempt to determine if there is any speed sensitive phenomenon in flapper valve operation. Valve motion is measured at various speeds in a reciprocating residential refrigerator/freezer compressor. Laser Doppler Velocimetry is used to measure the velocity of a point on the flapper at the center of the port for the suction valve. This velocity data is numerically integrated to produce displacement as a function of crank angle for each speed. An attempt is made to correlate compressor speed with any behavior that might either improve compressor performance or, conversely, decrease valve life.
