Abstract : In refrigerator designs, the linear compressor is preferable to the recipro-type compressor, due to its higher energy efficiency. The
linear compressor’s valve system, however, causes significant noise, not only in the steady state but also in the transient state. To accurately
predict the behavior of the suction and discharge valve system in both states, the interaction between the fluid flowing through the
valves and the structural deformation of the valves needs to be understood. In the present study, the steady-state behaviors of the valve
system were numerically analyzed using ADINA software, which takes fluid-structure interaction (FSI) into account. This computational
analysis thereafter was experimentally validated. The effects of a pre-load of the conical compression spring on the dynamic characteristics
of the valve system also were analyzed.
