Summary

Experimental research on the oil-gas separator was conducted to improve the performance of electric driven scroll compressor used in eco-friendly HEV/EVs. The compressor used in the test was “back pressure” method type by oil and an oil separator was made in the discharge chamber to manage the adequate back pressure. The pressure drop could be occurred when the refrigerant passing to oil separator. It makes input power increase and COP decrease. Various parameters of the oil separator— the length of vortex finders; installation angle; and the inlet, outlet diameters— related to the pressure drop were considered. The installation angle and the outlet diameters had no significant effect on the pressure drop; however, the pressure drop decreases as to the length variation of the vortex finder and the inlet diameter. As to the vortex finder length decreased and the inlet diameter increased, the input power of the compressor is decreased about 4.12% and the COP is increased about 2.66%.
