The Chiller R-454B is an excellent alternative both for new equipment and for the reconversion of chillers that work with R410a that use scroll compressor.
What should be known before a conversion or purchase of Chillers with R-454B?
- R-454B is a mixture of R32 and R1234yf.
- R454b refrigerant offers approximately 3% less capacity, but has the benefit of a GWP value as low as 467, making it a potentially long-term solution.
- R454B has slightly lower capacity than R410A but better efficiency. Chillers with R452B are best suited for hot climates.
- Many chiller factories have announced that they are manufacturing scroll compressor coolers. with R-454B. Many R-454B air-cooled chillers are now available in capacities from low refrigeration tons to 100-ton equipment.
- R-454B refrigerant is an HFO / HFC blend that does not deplete the ozone layer, it has a GWP level of 467, the lowest among refrigerants currently available for scroll compressor technology.
