    charging a system

    If you're charging a system with the refrigerant tank upside down will it come out as a liquid and harm the compressor.

    Yes, it will come out as a liquid.

    Yes, if not managed in some way, it CAN damage the compressor.


    That said, I charge liquid all the time, and some refrigerants require that they be withdrawn from the cylinder as a liquid.

    charging your own system with out knowledge of proper procedure is dangerous for you and your equipment. call a pro and save yourself some money.

    Yes, if compressor running.

    Actually, I'd be more afraid of putting liquid into a non-running compressor.

    A running compressor is generating heat which would help to evaporate any stray liquid that makes it that far.

    As I stated before, I charge liquid almost exclusively (except for very small critically charged systems) and have not damaged a compressor this way.

    A little care taken to meter the refrigerant into the system goes a long way.

    Either that, or you have a LOT of wasted time on your hands waiting for a 50 of 22 to boil off. I'm not that patient.

    There are also devices available to do it for you. I also use these for charging azeotropes in the same small, critically charged systems where I cannot charge with vapor and need precise control over the amount of refrigerant used.
