I want to get into the Car Air Conditioning business here in Spain, and I need help on equipment choice. My question is, although I do not intend to get into the domestic air conditioning business at this time, I would prefer to buy equipment that can do both. I am guessing that a vacuum pump with the highest CFM rating is better than one with a lower rating. Is this correct? can you have too high a rating one, for small systems like car A/C?
Is there a bible of Oil/Refrigerant quantities for cars, that is available for European models?
Oil/Dye injector units. Do I understand things correctly when I say that they are a vessel with a screw top lid, you fill them up with the required amount of Oil, the oil is squirted into the evacuated system (via the incorporated valve), when putting new refridgerant into the system? If so, is there not a small amount of air left in the top of the oil vessel, which also goes into the system, or is it of no significance?
Sorry for so many questions, really would appreciate positive help in this matter.
TIA
Mark.
