가변 용량형 압축기 ECV 내부의 유동특성에 관한 수치해석 연구 Numerical Analysis Study on Flow Characteristic Inside Variable Displacement Compressor of ECV
pp.167-172
In this paper, the current of ECV block is connected to compressor crankcase on which the Pc port of Ps port Euro is formed(Type-1). Pc Port Internal Bellows are supposed to be affected by changes at the flow of refrigerant to the solenoid valve inside inhalation. There is Ps port at the direction of flow characteristic in predicting and analyzing. At suction pressures of 0.2MPa and 1.5MPa, maximum flow rates become 46m/s and 129m/s respectively. The refrigerant is discharged by compressor rotation around the axis of rotation from the inflow of port(Pd)(Type-2). By predicting and analyzing inlet flow, suction pressures become 2.7MPa and 3.6 MPa when maximum flow rates of 177.5m/s and 205m/s are affected on Pc ports of Euros with pressures of 1.2KPa and 3.8KPa respectively. This study result can be applied as the basic data for design of ECV.
