Mixing refrigerants is generally discouraged because it can lead to reduced efficiency, increased pressure, and potential damage to the refrigeration system. Different refrigerants have varying properties, and combining them can alter the thermodynamic characteristics, making the system less effective and harder to service. Additionally, the mixture may not be compatible with existing oils or components in the system, leading to further complications. It's essential to follow manufacturer guidelines and use the designated refrigerant for optimal performance.
Oils are examples of hydrocarbons and hence they contain carbon and hydrogen as the elements.
They used inks make of charcoal and oils. They also used clay tablets, wax, and thin wood, and papyrus.
A terpene solvent is made of citrus oils or pine trees. Terpene solvents are organic and can be used as substitutes for turpentine.
Emulsion is combining oil with water. For instance, soap causes oils to bind with water, so soap is an emulsifier.
What is the Material compatibility in relation to refrigeration oils?
These oils must resist to high temperatures and to oxidation.

Hydraulic oils are substances that are hot, while refrigeration properties are cold.
There are different types of refrigerant oils. Refrigerants such as R22 and R12 usually use mineral oil. But some of blended refrigerants like R410A can sometimes use a poly oil. These oils can not be blended together. So a system that already has a refrigerant with mineral oil must be charged with refrigerants with the same oil.

Floc in refrigeration oil is wax that has separated out from oil containing parathene.
It's ability to operate and perform in a stable manner in an environment consisting of other materials such as rubber seals or gaskets and different metals and coatings within the refrigeration system without any chemical reactions or elastomer breakdown occurring when operating within varying temperatures differentials.
The oils commonly used with HFC-134a (R-134a) refrigeration applications are primarily polyol ester (POE) oils and alkylbenzene oils. These synthetic oils are preferred due to their compatibility with HFC-134a and ability to maintain proper lubrication at various temperatures. POE oils are particularly popular because they have good solubility with HFC-134a and provide excellent thermal stability.
