IIR document

An experimental study on energy consumption reduction opportunities for automotive air conditioning systems.

Author(s) : ZIETLOW D., SHARMA A., MEYER J.

Summary

The air-conditioning systems studied in this article used refrigerant R134a in the baseline system that consisted of an orifice tube, swash-plate compressor and an extruded-tube condenser. Modifications to this baseline system included a scroll compressor, a thermal expansion valve, and a sub-cooled condenser. Experiments were performed for nine different operating conditions designed to cover the entire range experienced in automotive air conditioning systems. The combination of components tested resulted in 28% lower power consumption and consequently 24% higher COP when compared to the baseline system.
