In addition to pressure, what other aspect is essential for R-410A performance?

Refrigerant purity is essential for the performance of R-410A because any contamination within the refrigerant can lead to a host of problems, including decreased efficiency and system failures. R-410A is a blend of hydrofluorocarbons (HFCs), and the presence of impurities can alter its thermodynamic properties, which directly impacts the cooling capacity and performance of HVAC systems. Impurities such as moisture, air, or other refrigerants can cause acid formation, leading to corrosion and damage to the compressor and other components in the system. Additionally, the efficiency of the heat exchange processes may be compromised if the refrigerant does not maintain its intended chemical properties. Therefore, ensuring high refrigerant purity is crucial for optimal operation and longevity of the cooling system.
