Zeotropic Blends

The properties of zeotropic blends are somewhat different than traditional refrigerants. Zeotropic blends shift in composition during the boiling or condensing process. As the blend changes phase, more of one component will transfer to the other phase faster than the rest.

Note! % by mass

The changing composition of the liquid - fractionation - causes the boiling point temperature of the refrigerant to shift as well. The overall shift of temperature from one side of the heat exchanger to the other is called the temperature glide.

Azeotropic Blends

Azeotropic blends behaves as a single component refrigerants even though they are blends. Single component refrigerants and azeotropic blends have boiling (bubble) points and condensation (dew) points equal to each other - simply called boiling point.
