Summary

Carbon dioxide air conditioning units were installed in two city buses. The two buses were tested "on the road" during summer 1997. By the end of October, the air conditioning systems of the two buses had been running together for more than 860 hours proving that CO2-systems fulfill important on-the-road requirements. The first part the paper presents and discusses typical on-the-road data. In the second part, the compressor of the transcritical cycle is discussed in detail. Indicator diagrams were measured with the first and second generation of the compressor prototype. Comparison of the two compressor versions shows significant differences in the measured indicator diagrams mainly due to the modified discharge valves.
