What modification has been made by manufacturers to the compressors used in R-410A equipment?

Manufacturers have indeed made modifications to the compressors used in R-410A equipment, particularly by increasing the wall thickness. This adjustment helps accommodate the higher pressures at which R-410A operates compared to older refrigerants like R-22. R-410A operates at approximately 1.6 times the pressure of R-22, requiring compressors to be built more robustly. The increased wall thickness helps ensure reliability and safety, reducing the risk of leaks or compressor failure under the heightened pressure conditions.

This design change is crucial because R-410A is a more environmentally friendly refrigerant with better thermodynamic properties, but it must be paired with hardware that can withstand its physical demands. The structural enhancement of the compressor not only supports higher pressures but also contributes to the overall efficiency and longevity of the equipment.
