When performing an AC recharge or repair, it is considered best practice to replace the accumulator or receiver-drier and to evacuate the system thoroughly to remove moisture and old oil residues. Beyond lubrication, this oil is responsible for sealing the internal vanes or pistons against the cylinder walls, which is essential for maintaining the high pressures required for refrigerant flow.
Understanding Air Condition Compressor Oil Types and Their Functions
Neglecting the correct type or level of oil can lead to premature component failure, reduced cooling efficiency, and costly repairs down the line. Polyolester (POE) Oil: The standard for R-134a and R-1234yf systems; offers superior chemical stability.
Modern vehicles have transitioned from older R-12 refrigerant, which used mineral oil, to newer, environmentally friendly options like R-134a and R-1234yf. Alkylbenzene (AB) Oil: A high-performance synthetic often found in heavy-duty or commercial HVAC applications.
Exploring Air Condition Compressor Oil Types and Their Functions
Understanding the Core Functions The primary role of air condition compressor oil is to lubricate the intricate moving parts inside the compressor, including pistons, bearings, and vanes. If the viscosity is too low, the oil will not provide adequate lubrication, leading to metal-on-metal contact.
