The boiling point of a refrigerant is fundamentally important in a refrigeration cycle as it establishes the pressure conditions under which the refrigerant transitions between liquid and vapor phases. This relationship allows engineers to design systems that operate effectively within specified temperature ranges.

In refrigeration, the refrigerant must absorb heat at low temperatures during the evaporation process while maintaining a corresponding pressure that facilitates this phase change. By understanding and applying the boiling point for a given refrigerant, technicians can predict the pressure that will be present in the evaporator and the condenser. This ensures that the system operates efficiently and within the design parameters to achieve the desired cooling effect.

Moreover, the boiling point also influences the selection of refrigerants for various applications, since different refrigerants have different boiling points that determine their suitability in specific conditions. Hence, knowledge of the boiling point and its implications for pressure conditions is crucial for achieving reliable and efficient refrigeration performance.
