Performance Analysis of Different Refrigerants in Automobile Air Conditioning Equipment Using Variable Capacity Compressor

In this study, the experimental performance of use R1234yf refrigerant al-ternative to R134a in an automobile air conditioning system with var-iable capacity compressor was investigated. The conditioner con-sists a variable compressor, evaporator, condenser, liquid tank and expansion element. is equipped computer-aided control systems obtain desired conditions data col-lection for measuring collecting data. Tests were per-formed at different speeds condenser evaporator inlet flow temperatures. Energy analysis applied obtained experi-mental results presented comparative graphs. results, it seen that while cooling effect coefficient outlet generally decreased both refrigerants increase speed, mass rate refrigerants, temperature, heat discharged from power increased. cases where evaporatör airflow temperature low, has been observed change very small speed
