Have the mechanic remove any remaining mineral oil from the system. vacuum pump lowers boiling temp of water, allowing moisture to leave system as vapor. Also be sure to properly cut and ream tubes to remove any burs. Proper flux - Use the correct flux for each application of base metals. The lower piece count also. Each type of refrigeration can use air-cooling or water-cooling, or both, to transfer heat from the outside of the system to the environment. How the Conventional Oil Separator functions: Refrigerant gas from. How do I Add AC Compressor Oil? You probably don’t often think about how your air conditioning system makes cool air on a hot day. Repairs requiring opera-tions in a refrigeration system are rather costly. Foreign matter that can enter refrigeration system are filings, shavings, dirt, solder, flux, metal chips, bits of steel wool, sand from sandpaper, and wire from cleaning brushes 6.
