Abstract
In this study, an experiment on an air conditioning test bench was performed to verify the possibility of fuel economy simulation for the SC03 mode, North America fuel economy certification mode with a/c on condition, one of the vehicle fuel economy evaluation modes. The air conditioning test bench used in this study had each chamber simulating the actual vehicle air conditioning system and the controlling temperature, humidity, and air flow velocity to reproduce environmental conditions. Reliable results were obtained about the compressor RPM and inlet air velocity in front of the condenser corresponding to vehicle speed and air velocity in front of the vehicle, respectively, in the simulation of the SC03 mode, previously performed in CWT, in an air conditioning test bench. It was also discovered that there was a distinct difference in the fuel economy depending on the difference in the compressor displacement in the simulation test of the SC03 mode in the air conditioning test bench under various displacement conditions of the compressor.
