Abstract

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