| Abstract |
The compressor’s efficiency affects on the fuel consumption of the vehicle because the compressors for car air-conditioning system are operated by engine-driven. Especially, the refrigerant is being changed recently from R134a to substitution refrigerant to protect environment pollution that people concerned about. However, that leads to lower efficiency of the car air- conditioning system and worse fuel consumption of the vehicle. Thus, this paper is focused on the methods for improvement of the compressor’s efficiency that affects on the fuel consumption of the vehicle by numerical analysis for compressor’s performance and the measurement of cylinder volume and pressure when the compressor is being operated. |
