What is the difference between the boiling point and condensing point in blended refrigerants called?

The difference between the boiling point and the condensing point in blended refrigerants is referred to as temperature glide. This phenomenon occurs because blended refrigerants, which are mixtures of different refrigerants, do not have a single, constant boiling point like pure refrigerants do. Instead, they evaporate and condense over a range of temperatures.

When a blended refrigerant is utilized in a system, as it absorbs heat and changes from a liquid to a vapor (boils), it does so at various temperatures rather than at one specific temperature. This range is indicated by the temperature glide, which can affect the efficiency and performance of the refrigeration system. Understanding temperature glide is essential for technicians to properly charge the system and ensure optimal operation.

In contrast, concepts like temperature slip, temperature rate, and electraglide do not accurately capture the distinct behavior of blended refrigerant mixtures as they transition between phases. Therefore, temperature glide is the correct and most relevant term to describe this characteristic of blended refrigerants.
