Retrofitting an automotive air conditioner with R134a, additive, and mineral oil.

Author(s) : JETTER J. J., DELAFIELD F. R.

Summary

The system retrofitted with R134a and the oil additive survived a compressor durability test, while the system retrofitted with R134a and no additive did not survive the durability test. Lubricants are available that are miscible with R134a. However, if lubricant additives prove to be successful, miscible lubricants may not be needed for retrofitting some automotive systems. The retrofitting procedure might be simplified and the cost to consumers might be reduced. It has not been determined if retrofitting systems with R134a and oil additives is feasible for a wider range of operating conditions and types of equipment, including the applicability of orifice tube/suction accumulator systems.
