Explain what Refrigeration Compatibility means in relation to refrigeration oils?
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.

Why refrigerant should be miscible with lubricating oils?
Refrigerant should be miscible with lubricating oils to ensure proper lubrication of the compressor components. If the refrigerant and oil are not miscible, it can lead to oil dilution, reduced lubrication efficiency, and potential compressor damage. Miscibility helps to maintain proper lubrication and prevent premature compressor failures.
A refrigerant oil that is hygroscopic?
One of the refrigerant oils that has hygroscopic properties include Argamine - 15N4. It has multiple other synonyms such as Arginine - 15N4 Hydrochloride. It is a thick oil that is white in appearance.
Can you use r 134a refrigerant instead of r 12 refrigerant?
The short answer is yes. However, the A/C system must be retrofitted (changed from R-12 to R-134a). Many people believe that you can simply add R-134a in place of R-12 without retrofitting. However, this is not recommended because you can do damage to the A/C system. Remember that you are mixing two different refrigerants and refrigerant oils.
What is the approximate boiling pressure for refrigerant oil in a systeme?
The approximate boiling pressure for refrigerant oil in a system will depend on the specific type of oil being used and the operating conditions of the system. Typically, refrigerant oils have boiling points ranging from 150-350°C under normal operating conditions. It is important to consult the manufacturer's specifications for the exact boiling pressure of the oil being used in a specific system.
What is trichlorothane?
Trichloroethane is a chemical compound used as a solvent and in the production of other chemicals. It can also be used as a refrigerant and in the extraction of oils. However, it has been largely phased out due to its harmful effects on health and the environment.
Can 134a refrigerant be mixed with 404a refrigerant?
ive crossed used 404 in a 134a motor and vice versa. 134a in 404 and r410 motors the big deal is to use ester oil which mixes with all 3 oils. miscible. 404 delivers a higher head pressure. so 404 in 134a motors are not real prepared for start-up. (warning).
How much freon requires?
Depends on the year make and model. You can find the information out on the link below. Follow the icon for "Find your car's low side port" it will also give you information on the amount and type of refrigerant and what oils to use.
How is carbon tetrachloride used?
Carbon tetrachloride was historically used as a solvent for oils and fats, as a refrigerant, and in fire extinguishers. However, its use has significantly declined due to its harmful effects on human health and the environment.
What is chemical stability in relation to refrigeration oils?
These oils must resist to high temperatures and to oxidation.
