Refrigerant 410A Certification Practice Test

The design change made to compressors for R-410A systems focuses on enhancing durability through increased wall thickness. This adjustment is crucial because R-410A operates at higher pressures compared to older refrigerants like R-22. The increased wall thickness in compressor construction helps manage these elevated pressures, reducing the risk of mechanical failure and prolonging the service life of the compressor. By ensuring that the physical structure of the compressor can handle the demands of higher pressure, manufacturers enhance the overall reliability and efficiency of the HVAC system. This design consideration is essential for maintaining performance and safety in R-410A systems.
