Which refrigerant type is used in high pressure appliances?

Explanation:
High‑pressure appliances need a refrigerant that can operate effectively at higher system pressures. R410A is designed for that purpose and is widely used in modern high‑pressure equipment because it maintains performance at those elevated pressures. In contrast, R503 is used for low‑temperature refrigeration, not high‑pressure appliances, and R134a operates at lower pressures than R410A. R502 is an older blend that's being phased out in favor of newer high‑pressure options like R410A. So the refrigerant type used in high‑pressure appliances is R410A.
