What is the Zeotropic Refrigerant?

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.
