a blended refrigerant with less than 10F temperature glide, 41oA and 404A are examples.
Fractionation occurs in certain blends of refrigerants due to the different boiling points of the individual components in the blend. As the refrigerant evaporates or condenses during the refrigeration cycle, the refrigerant components can separate based on their boiling points, leading to changes in the composition of the refrigerant blend and potentially impacting system performance.

A colour similar to trees. A shade of the shallow sea.
In a zeotropic blend, the blends boil out at different temperature but at the same pressure. typical example is R704

What is a near-zerotopic blend
Temperature glide refers to the range of temperatures over which a blend of refrigerants evaporates or condenses during a phase change process. This phenomenon occurs because the individual components of the blend have different boiling points, resulting in a temperature range rather than a single temperature for the phase change process.
A zeotropic refrigerant blend is a mixture of two or more refrigerants that have different boiling points, resulting in a temperature glide during phase changes. This means that as the mixture evaporates or condenses, it does so over a range of temperatures rather than at a single temperature. Zeotropic blends can improve system efficiency and performance by allowing for better heat transfer and reducing the risk of refrigerant fractionation. Common examples include R-407C and R-410A.

Cotton blend would be a combination of cotton fibers with either wool or man-made fibers to create a blend.
R-421A is an R22 alternative refrigerant. It is licensed under the Choice brand name ( Choice R-421A). It is a blend of 58%/42% R-125 and R-134a. It is a non-ozone depleting refrigerant, and the only 2-component refrigerant blend to replace R22. For more information, visit www.rmsgas.com.
Temperature glide
A zeotropic refrigerant is a type of refrigerant blend that has a varying composition of components, which means it does not evaporate or condense at a constant temperature. Instead, it exhibits a temperature glide during phase changes, where the temperature changes gradually over a range rather than at a single fixed temperature. This property can enhance efficiency in certain cooling applications but may also complicate system design and operation. Common examples of zeotropic refrigerant blends include R-407C and R-410A.
An azeotropic refrigerant blend has a constant boiling point and composition throughout the phase change, behaving like a single substance during evaporation and condensation. In contrast, near-azeotropic or zeotropic refrigerant blends exhibit varying compositions and boiling points, leading to temperature glide during phase change, where the refrigerant does not boil or condense at a single temperature. This difference affects system efficiency and performance, with azeotropic blends generally providing more consistent thermal properties, while zeotropic blends may offer better energy efficiency and lower environmental impact.
temperature glide occurs when the refrigerant blend has various temperatures as it evaporates and condenses at a single given pressure.
