    You have been given reasonably accurate information.

    There have been numerous discussions aboutl;iquid charging versus vapor charging on this site. I won't get into that. Suffice it to say that I have dumped one hell of a lot of liquid into the suction side of equipment and have yet to damage a compressor.

    I also know what compressors are more sensitive to liquid damage by way of their construction and am much more careful with them.


    There are devices like the Kwik Charge, that are designed to flash that liquid for you. They are nice, but hardly necessary.

    hey JJJJJJJJJJJJJJP!

    Ray,

    yeah, there are air cooled compressors, refrigerant cooled compressors,
    screws, scrolls, tin can, semi hermetic, rotary, centrifugals and such!

    each type of compressor can tolerate more liquid than another.

    if you look at a refrigerant cooled copeland semi, the refrigerant must go through the end bell of the compressor which is a really cool, like neet! manifold which by itself will eliminate liquid, and then go over the entire motor, which if low on refrigerant? will be hot! that should flash off any remaining liquid! and then into the suction valve!!!! While i have seen these oil slugged a million times!! with broken connecting rods!
    I have rarely seen one liquid slugged!
    I personally HAVE liquid slugged a small compressor a long time ago!
    it goes- KLUNK KLUNK BZZZT!

    on the other hand a copeland air cooled semi like an LALA in a small referigeration application the liquid refrigerant would go directly into the suction valve!!!!

    I CAN'T believe that you would actually admit something like that, Frank.

    I know that I would never admit to having personally liquid slugged a Copeland 'K' body compressor while working on a small, R-12 door cooler about 13 years ago. NEVER!

    The apartments holding up. School goes okay. We started the last unit Friday- Air Conditioning and Psychometrics. After that we have to finish off electrical and then we spend the days in the shop doing our projects. I write my Ozone Depleting Substances card on Wednesday the 31st. I got a copy of An Inconvenient Truth, and the CFC manual that I'm going to go over a few times in the next week to get that card.

    I don't feel too awful bad about it. I was the apprentice back then.

    It taught me something, as have all the mistakes and missteps that I have made along the way.

    Making a mistake isn't the problem. Not LEARNING from that mistake is.

    That is the lesson that I try to hammer home to every noob that I talk to.

    You WILL screw up. It isn't a matter of IF, but WHEN.

    What is most important is what you LEARN from it.

    i would never ever admit to filling a 1,250 ton chiller on the condenser loop and leaving the small 3/4" vent open, and spraying water all over the 4600 volt/ 2,500 amp switch gear and the explosion blowing the doors off the panel!!

    hypothetically speaking! that would suck!

    22 years ago my official training went like this!

    1. ride with this guy for a day, he is really smart! "beer can cold and sweating "

    2. ride with this guy for a day he is really smart! "ambient plus 30"

    3. DAY 3! do you feel like you are good enough to do this on your own? "YES"

    4. DAY 4! after lunch, here is your truck! go get the parts you need! WHAT PARTS???

    5. sell a lot of new air conditioners! because I do not know how to troubleshoot them!

    6 go to alot of RSES meetings, buy alot of books,

    7 spend literally thousands of hours reading formentioned books!!

    8. ask as many questions as i can!

    9. read lots of books!
