Effect on January 1, 2025, the use of R-410A refrigerant
R410A and R454B are refrigerants; however, R454B is regarded as more ecologically sustainable due to its lower global warming potential (GWP) and absence of ozone depletion potential. R454B has similar efficiency to R410A and, in certain instances, it may even demonstrate slightly superior performance. Nevertheless, R454B exhibits a slight flammability characteristic, which renders it unsuitable for utilization in current R410A systems unless the compressors are upgraded.
Effectiveness
R454B systems exhibit around a 5% higher level of efficiency compared to R410A systems and may necessitate a reduced amount of charge.
Interoperability
R454B is a suitable substitute for R410A, as it can be utilized with current equipment with minor adjustments.
Nevertheless, components must be compatible with flammable refrigerants to prevent them from becoming a source of fire.
