CEN has released the enquiry version of prEN 378:2025 for national standardisation committee review. The revision introduces a risk-based design approach that eurammon welcomes, though charge limit restrictions and prescriptive safety caps remain barriers to wider natural refrigerant adoption.
A 2026 review by NIST researcher Mark McLinden in the International Journal of Refrigeration examines the thermodynamic rationale behind the adoption of fluorinated gases and the engineering challenges that will accompany their phase-out. The paper argues that upcoming F-gas restrictions will reverse the traditional design approach: systems must be built around the properties of the chosen working fluid rather than the other way around.
