Experimental Investigation of AC System Performance with HFO-1234yf as the Working Fluid 2010-01-1207

Experimental investigations have been carried out to determine the AC system performance with HFO-1234yf as the working fluid. System level bench tests have been conducted with an AC system from a 2008 MY mid-sized sedan. The cabin interior condition is held constant at 20°C and 50% RH and evaporator airflow rate is varied from 5 to 9 m₃/min (83 to 150 lps). The dry bulb temperature for the engine compartment is varied from 25 to 45°C. The compressor speed is varied from 800 to 3000 rpm and the air velocity over the condenser is varied from 2 to 10 m/s (546 to 2730 lps). Detailed test results have been presented in the paper.
