Abstract

The purpose of this study is to optimize the amount of oil charge in the electric driven scroll compressor for eco-friendly vehicles. R134a is used as the refrigerant in the vehicle and Polyolester (POE) oil as the compressor oil. The initial amount of oil was increased at 20 g intervals from 40 g to 120 g, and at each initial amount of oil charge, the back pressure is measured at each step of the complex durability test and under each condition of the performance test. Throughout the test, it is found out that the optimum amount of oil is determined by the back pressure, which is 80 g in this test. The performance of a system is compared with pull-down tests in the actual air conditioning system, and the optimum amount of oil was confirmed. A complex durability test was also evaluated and verified for the durability of the compressor with the confirmed amount of oil.
