R-410A operates at higher pressures than R-22 due to its thermodynamic properties and the fact that it is designed to work more efficiently in modern HVAC systems. Typically, the suction and discharge pressures of R-410A can be approximately 40% to 70% higher than those of R-22.

This increase in pressure is significant because it affects system design and component selection. For example, components like compressors, evaporators, and condensers must be rated to handle these higher pressures to ensure safety and optimal performance. Understanding these pressure differences is critical for technicians working with these refrigerants, as using R-410A in a system designed for R-22 could lead to equipment failure or safety hazards.

When comparing the options might give insights into the nuances of pressure differences, only the range of 40% to 70% accurately represents the typical performance characteristics of R-410A in relation to R-22. It is important for technicians and engineers to understand this when designing or servicing systems to ensure reliability and efficiency.
