What type of oil is most commonly used with CFCs and HCFCs?

• A. Vegetable oil
• B. Animal fat
• C. Mineral oil
• D. Synthetic oil

Answer: (C)

The most commonly used oil with CFCs (chlorofluorocarbons) and HCFCs (hydrochlorofluorocarbons) is mineral oil. This is due to the compatibility between mineral oil and these refrigerants, as well as mineral oil's favorable properties such as stability and performance under varying temperatures and pressures. Mineral oil operates effectively in the refrigeration and air conditioning systems that utilize CFCs and HCFCs, helping to lubricate components such as compressors and reducing wear and tear. Its low viscosity allows for easy flow and distribution throughout the system, which is crucial for maintaining efficient operation and ensuring that all moving parts are adequately lubricated to minimize friction. In contrast, other types of oils, like vegetable oil or animal fat, are not suitable for use in refrigeration systems due to their higher viscosity and the potential for degradation at low temperatures, which could lead to clogs or system failures. Synthetic oils, while they might be effective for certain applications, are less commonly used with CFCs and HCFCs in traditional HVAC systems, making mineral oil the standard choice for these refrigerants.
