This study developed the electronic expansion valve using CO2 refrigerant. The electronic expansionvalve consist of bellows, stepping motor, 3-stage reduction gear, poppet and orifice. Structural and flowanalysis of electronic expansion valve are carried out using commercial code ANSYS and CFX version14. Structural analysis were conducted for three type bellows(basic, rib and straight type). As a results,value of maximum equivalent stress showed that basic type was smaller than rib and straight type.
