The interaction between refrigerant and oil is critical for the efficient operation of the entire cooling cycle. Old oil can become contaminated with metal shavings or moisture, reducing its effectiveness.
Enhancing R134a PAG Oil System Performance and Compatibility
However, it also serves to carry heat away from the compressor and helps to seal the internal components by maintaining the flexibility of the seals and hoses. Visible debris or sludge exiting the compressor when it is removed for inspection.
Using a viscosity that is too low will result in poor lubrication, while a viscosity that is too high can cause increased drag and reduced cooling performance. Without the proper PAG oil, the rubber components can degrade, leading to leaks and a loss of cooling efficiency over time.
Enhancing System Performance with the Right R134a PAG Oil Viscosity
This specific chemistry is required because traditional mineral oils are not miscible with the HFC-134a gas. PAG oil is hygroscopic, meaning it absorbs water from the air.
