3 Questions to Herrmann Renz, member of the Technical Committee of eurammon
The revised F-Gas Regulation with its direct and indirect prohibitions is a major challenge for the refrigeration and air-conditioning sector. The tasks that have to be mastered and the chances these then offer in turn are explained by eurammon expert Hermann Renz, member of the Technical Committee of eurammon and Technical Programs Manager at Bitzer Kühlmaschinenbau GmbH.
Hermann Renz: The roadmap features a phase-down through to 2030. At first glance this seems to be a long time, but the branch is already being forced to set the points in a sustainable direction in the long term. It is also foreseeable that new challenges will emerge in the future. The EU has meanwhile announced a further reduction in CO2 emissions by 2050, which will result in an additional need to act.
2. Does it make sense to convert existing equipment or is it better to invest in a new system that will meet future requirements?
Hermann Renz: Even if existing systems could continue operations through to 2030 when operated with recycled refrigerants, it often makes commercial sense for well maintained systems that are operating efficiently to be converted to refrigerants with a low GWP. However, it has to be ensured that there are no disadvantages in terms of energy efficiency due to the change-over. As far as older equipment is concerned, new investment is recommended here as this is often far more profitable to operate thanks to more developed technologies.
