What should you avoid when transferring a Zeotropic blend?

When transferring a Zeotropic blend, it is essential to avoid allowing temperature variations. Zeotropic blends, such as refrigerant 410A, consist of multiple components that have different boiling points. If there are significant temperature fluctuations during the transfer process, it can lead to fractionation, which is the separation of the components in the mixture. This separation can result in a situation where the refrigerant is not in the intended composition, affecting its performance in the system.

Maintaining a consistent temperature helps ensure that the blend remains homogeneous. This practice is crucial when charging or recovering refrigerants to ensure the proper mixture enters the system and operates efficiently. In contrast, transferring as a gas or liquid, or using appropriate fittings, are generally necessary procedures to correctly manage refrigerants and are not inherently problematic when done correctly.
