Valeo

CO2 is 1400 times less harmful than a traditional gas when used as a refrigerant in automobile air conditioning systems ! But the entire system has to be modified to withstand the new pressure, which increases from 23 to 160 bars, including the compressor, exchanger, expansion valve and evaporator. Roman Bonamy began working on this project during his graduate project in 2006, developing the specifications for developing the test bench. He coordinated the work between several research sites and customers in an international context. Finally, he developed a calculation tool and a database for a theoretical performance model.

He needed no close mentoring, and did the work of a young engineer, as if he already had two or three years of experience. After three months, he had already obtained results. I appreciated his thoroughness and curiosity. He never left out a single detail. He perfectly understood the challenges and identified the people who could help him in our organization, which is admittedly quite complicated. Valeo has 70,000 employees working in 11 different fields.!

Today, the project is in the implementation phase
