Alkylbenzene ISO 32 cSt synthetic refrigerant oil is miscible and suitable to use with which of the following refrigerants?

🔍 Key Concepts

• Alkylbenzene (AB) oils and which types of refrigerants they are commonly paired with • Difference between HCFC and HFC refrigerants in terms of oil compatibility • Why miscibility between oil and refrigerant is important for oil return to the compressor

💭 Think About

• First, identify which of the listed refrigerants are HCFCs and which are HFCs or newer low‑GWP refrigerants • Recall which refrigerants typically require polyolester (POE) or polyalkylene glycol (PAG) oils instead of alkylbenzene oils • Think about traditional marine and commercial refrigeration systems that used alkylbenzene oils and which refrigerant was most common in those systems

✅ Before You Answer

• Verify which refrigerant on the list is an HCFC commonly used with mineral or alkylbenzene oils • Check which refrigerants on the list are pure HFCs that usually require POE oil for proper miscibility • Confirm that the chosen refrigerant has a well‑documented history of compatibility with alkylbenzene ISO 32 cSt synthetic refrigerant oil
