R-410A refrigerant does not have a single boiling point. This is because it is a zeotropic mixture, meaning its components (R-32 and R-125) have different boiling points.

Here's what you need to know:

* The boiling point of R-410A varies depending on the pressure. At atmospheric pressure (1 atm), the boiling point is around -51.4 °C (-60.5 °F).

* As the pressure increases, the boiling point increases. This is why R-410A can be used as a refrigerant in systems operating at various pressures.

Important Note: When working with refrigerants, it is crucial to consult the specific data sheet or technical documentation for the blend you are using. This will provide accurate information about boiling points and other relevant properties at different pressures.
