The future of refrigerants at MCE 2026: from F-Gases to alternatives and new skills
At MCE 2026, focus on F-Gas, alternative refrigerants, and skills for the transition of the HVAC/R sector.
Refrigerants are currently at the heart of the transformation of the HVAC/R sector, driven by regulatory changes, technological innovation, and new operational requirements. At MCE 2026 , discussions between companies, technicians, and operators clearly highlighted how the transition has now entered a concrete phase, in which choices regarding refrigerants directly influence the design, installation, and management of systems.
It's no longer just a matter of replacing traditional refrigerants, but of addressing a structural change that involves the entire supply chain.
New F-Gas framework and operational implications
The evolution of the European regulation on F-gases is defining an increasingly stringent roadmap, with progressive limitations on the use of high-GWP refrigerants and a decisive push towards solutions with a lower environmental impact .
This change directly impacts the daily operations of industry operators. The regulation not only concerns refrigerant selection, but also affects the entire life cycle of systems: from design to leak management, recovery, and maintenance.
In this context, regulatory compliance becomes a central element in technical and strategic decisions.
Alternative refrigerants and technological innovation
In parallel with regulatory developments, the industry is accelerating the adoption of alternative, low-GWP refrigerants , including CO₂, hydrocarbons, and ammonia.
At MCE 2026, it was clear how technologies are rapidly adapting to these solutions, with systems designed to handle new operating conditions and ensure high performance. This process affects both new and existing systems, which increasingly require retrofitting or updating to align with new standards.
Technological innovation therefore becomes a key element in making the transition sustainable.
Skills and training: the real crux of the transition
One of the most significant aspects that emerged concerns the issue of skills . The introduction of new refrigerants entails significant changes in operating methods, with implications for the safety, management, and maintenance of systems.
The characteristics of new fluids, such as flammability or high pressures, require more advanced technical preparation and ongoing skills development. In this scenario, training and certification become essential tools to ensure proper use of technologies and support the industry's transition.
Towards an integrated transformation of the HVAC/R sector
The picture emerging from MCE 2026 highlights a transformation that goes beyond the simple replacement of refrigerants. The HVAC/R industry is moving toward a more integrated model, in which regulations, technology, and expertise evolve together.
For operators, this means adopting a more systemic approach, capable of combining environmental sustainability, energy efficiency, and regulatory compliance. The ability to anticipate changes and adapt to an ever-changing environment is now a crucial factor in addressing market challenges and seizing the opportunities of the transition.
FAQ
The regulatory developments discussed at MCE 2026 directly impact commercial and industrial refrigeration and advanced air conditioning, where the use of fluorinated refrigerants is still widespread. Applications such as large-scale retail trade, data centers, and industrial processes require highly reliable and operationally continuous solutions, making refrigerant selection crucial based on GWP, safety, and operating conditions. Design must therefore consider the use of CO₂, ammonia, or hydrocarbons, evaluating specific technical and regulatory constraints.
Replacing refrigerants subject to F-Gas restrictions poses significant design challenges: high pressures in CO₂ systems, toxicity management for NH₃, and ATEX requirements for flammable refrigerants. Added to this is the need to redesign components and system architectures (compressors, valves, safety systems). Furthermore, the availability of compatible components and regulatory standardization are not yet fully established, creating uncertainty in technological choices.
Alternatives to traditional refrigerants can offer high energy performance, but require careful design to realize their full potential. For example, transcritical CO₂ systems require optimization based on climate conditions, while ammonia guarantees high efficiency in industrial environments. The choice of refrigerant therefore impacts consumption, indirect emissions, and operating costs, making an approach based on LCC analysis and integration with energy recovery systems essential.
