Oil to freon ratio
Webb30 maj 2024 · When using r-134a instead of r-12, a complete oil change is required. Refrigerant R12 works on mineral, R134a – on synthetic. The cooling capacity of the equipment can decrease or increase by 5-10%. The R134a refrigerant molecules are smaller, increasing the likelihood of leakage through joints and seals. Webb1 maj 2014 · Oil in the A/C system is essential, primarily to lubricate moving parts, i.e. the compressor and the expansion valve needle. It also enables heat to escape from the compressor. As with refrigerant, oil in the A/C system must retain its chemical stability. However, it is vital to choose the right oil for the job.
