Which refrigerant is commonly used in light commercial refrigeration systems?

The use of R-410A in light commercial refrigeration systems is prevalent due to its efficiency and lower environmental impact compared to older refrigerants. R-410A is a hydrofluorocarbon (HFC) blend, which means it does not deplete the ozone layer, making it a suitable choice for systems designed to comply with environmental regulations aimed at reducing ozone layer depletion.

R-410A operates at higher pressures than some alternative refrigerants, which allows for a more efficient heat transfer process, enhancing the overall performance of the cooling system. Additionally, its thermodynamic properties make it effective across a range of temperatures and conditions typically encountered in light commercial applications.

The other choices, while they have their own applications, are either phased out or less commonly used in modern systems due to various factors such as environmental concerns, regulations, or inefficiencies compared to R-410A. Such considerations make R-410A a widely accepted refrigerant for current light commercial refrigeration needs.
