    Go to the "For Your Interest" area on the main page and there you will find a series of articles on both the theory behind and the practical application of properly charging systems.

    doing the best i can do norm......troubleshooting over the net and it was getting late....and as far as that i must of been tired cause i told him 1/4 ounce per foot and not half.....anyway i have worked for numerous contractors and everyone of them had different method.....now i have my method....putting them in everyday....if you would like you could stop by and i will take you on some tours of completed jobs and you can check the charge on mine....i think you will find i know superheat and how to charge air conditioner.....if not,well then maybe you can show me how real techs. do it?

    Norm, Norm, Norm,

    You may have lost an ( o ) somewhere,

    Do you really beleive some of the things you post,some of us are posting knowledge real knowledge for the real world. Anyone can refer someone to a book, I've seen the book I've read the book and I have written some of the book.

    I would bet that you beleive that a cap-tube is not a modulating metering device and that it is the same as a orifice or that a piston is like either of those two or that the metering device altogether denotes what type of charging should be used.

    Hmm I would like to see the book you wrote.

    A cap tube, oriface and piston all operate on the same principal - A pressure drop based on a specific load. The restriction is fixed. These all must be charged via superheat. A TXV gives a constant superheat once it receives a solid column of liquid which is charged by subcooling. The TXV is variable.

    Some here are assuming things I never said and attempting to put words in my mouth. I suggest you read my articles before you try to speak for me.

    And yes, purchase the book and read it!

    Doc they all work on the pressure drop theory, but to say that a cap-tube and an orifice and a piston meter and modulate the same way, is just plain wrong a cap-tube is a modulating device that works much more like a txv than a piston or an orifice, GEES O MAN

    Personally I think everything posted so far is wrong!We should be telling him that a heat pump that is 20 years old has outlived it's lifespan & to try & repair it would be a waste of time & money!
    Take your time & do it right!

    Eddy,

    I am afraid not, there is nothing remotely variable about a cap tube, it is a fixed metering device. The superheat is regulated by the restriction and the head pressure. The higher the head pressure, the more refrigerant flows just like an oriface or piston. What happens in the evaporator after the refrigerant enters it has no bearing on the cap tubes flow rate.

    You do seem convinced so I am open to a logical explanation.

    Every now and then one comes across a post that catches an eye.

    The only problem that exist with your post is if you actually think any of it was more than comedy.

    If this is your thought on how the refrigeration cycle actually works, I pity your clients and you owe them a huge thanks for allowing you to hack on their units.
    Amazing is it not LMTD? We have people posting their ignorance without any shame who openly claim to be service managers. When they should be asking questions, they are posting their ignorance. I have been waiting to allow them to post a little more and hang themselves before I post the way it really works.

    Hi Norm,

    Please go ahead and hang me first, then I will not only tell you how it works I will also supply you with the porper documentation to verify it.

    ( just for you info I have won a lot of money on this question)

    You got a live one here. You KNOW I want to take this one on and act like an ass while doing so, but I will let you instead as you will remain far more professional than I.

    Hey fat boy, you're about to get handed your hat and expose just how clueless you really are sir.

    LMAO gonna provide documentation on cap tubes lmgdao, have fun Norm!
    In the interest of remaining professional I will allow him the dignity of explaining himself since he is the one who made the claims regarding how a cap tube really works.

    Who knows, perhaps it is all a matter of semantics.

    Come on Norm,

    Forget the professional BS, go ahead and hang me you said ya could. I think you are scurrying to read up on it between posts. go ahed hang me high, and please don't worry about my dignity.Let me give ya a little common sense clue that you all may be able to relate to before you jump the gun and make fools of yourselves. If a cap tube were a fixed orifice don't you think they would of just used a fixed orifice ? Knaw on that a little while, as yur doing yur google search for "CAP TUBES REASON FOR BEING"

    Keep it friendly, polite and educational guys. Leave the egos at the door.

    Thanks

    Sure Boss, I have no interest in a flame war. Neither LMTD nor I have anything to prove. We have already established our credibility here.

    I'll let it go as hard as it is to do so. Knowing fat eddy he will continue to post and folks will catch on soon enough without LMTD and I making a point of it.

    Norm
