What is the main benefit of using R-410A over older refrigerants?

The primary advantage of using R-410A over older refrigerants lies in its increased energy efficiency. R-410A is a hydrofluorocarbon (HFC) that operates at higher pressures than some of its predecessors, such as R-22. This higher efficiency means that systems utilizing R-410A can provide more cooling output per unit of energy consumed, consequently leading to lower electricity bills for users.

Moreover, the design of air conditioning and heat pump equipment using R-410A incorporates advancements that optimize performance and energy use, aligning with regulatory standards aimed at reducing environmental impact. Enhanced energy efficiency contributes not only to savings for consumers but also to reduced greenhouse gas emissions when considering the overall energy needs of cooling systems on a larger scale.

Higher viscosity, lower operational pressures, and longer lifespan do not provide the same level of substantial efficiency benefits or are not particular features that significantly set R-410A apart from older refrigerants.
