What oil do you use in a refrigerator compressor?

What oil do you use in a refrigerator compressor?

Polyol ester (POE): this refrigeration oil is the most common type of synthetic lubricant being used with HFC refrigerants, like R134a.

What are the different types of refrigerant oils?

There are two main types of refrigerant oils:

• Mineral Oils, and.
• Synthetic Oils.

Which oil is used in HFC 134a refrigerant?

polyol esters
Most HFC-134a systems use a synthetic lubricants called polyalkylene glycol (PAGs) or polyol esters (POEs).

How do I know what compressor oil to use?

In general, you will want to select an oil that is specially formulated for use with the refrigerant being used in your commercial compressors. These lubricants are usually labeled distinctly to let you know that they contain additives for cooling, foam control, sludge control and more.

What is the best compressor oil?

For compressor oil, you want to use either SAE 20 or SAE 30 oil, where the latter is the more viscous of the two. If you live in a cold region, then it is better to go for SAE 20 compressor oil. Those who live in warmer places should use SAE 30. This is based on how the viscosity may change depending on the weather.

What kind of oil do you use with R-22?

mineral oil
R22 air conditioners use mineral oil and R410A systems use synthetic oil. The synthetic oil is generally more soluble with R410A than mineral oil is with R22.

What lubricants can be used with HFCs?

To achieve an acceptable miscibility between the refrigerant and the lubricant, polyolester oils (POEs) are normally used with HFCs. Polyvinyl ethers are also being introduced in some applications.

Can you use motor oil for compressor oil?

It is possible to use a standard weight motor oil in your compressor. While this isn’t the top recommendation, it could get you by. Generally, it is not recommended to run a multi-viscosity oil in a compressor since it might cause foaming issues. Sticking with a 20W or 30W oil is your best choice.

What can I substitute for compressor oil?

Non-Detergent Motor Oil. Motor oil can be used in place of air compressor oil, but it needs to meet a few important criteria if you don’t want to damage your compressor pump.

What oil is used with R22 refrigerant?

Refrigerant R-22 has been successfully used with mineral oil in residential air-conditioning and heat pump systems (AC/HP).

What refrigerant lubricant is compatible with R22 and R-410A?

POE OILS. POE oils are a family of synthetic lubricants. Unlike natural mineral oils, POE oils are completely wax-free and are the best choice of lubricants for use with the new generation of chlorine-free HFC refrigerants, such as R-410A.

Can you use POE oil in an R22 system?

The refrigerant R-22 is compatible with POE oils.

What is refrigeration oil?

Definition. The refrigeration oil serves as a hydraulic control, functional fluid and lubricating oil in refrigeration compressors under the influence of the refrigerant.

When should I replace refrigerant oil?

For Rotary Screw Compressors – Change the oil every 1000 to 2000 service hours. For Reciprocating Air Compressors – Oil change should be every 3 months.

What refrigerant lubricant is compatible with r22 and R-410A?

What type of oil do you use with R22?

R22 air conditioners use mineral oil and R410A systems use synthetic oil. The synthetic oil is generally more soluble with R410A than mineral oil is with R22.
