well thanks cmfici am glad someone likes it.thank you.i am a down to earth guy.i try to speak in every day terms.i hate tring to explain myself in tech terms.
i have recieved pm's from people on my exact spec which i do'nt mind helping anyone but i would rather anser the questions in here so i can help more than one or two.i have alot of questions on calpillary size and lenght outside diameter is .080 inside is .030 lenght is about 6 ft.A little something to think about with calpillary tubing..keep it long...too short and too big alows too much freon to pass though.this is bad one tha compressor has to work alot harder to feep up and 2 you have a bad chance of the freon still being in a liquid form when it reaches the compressor.i know alot people have a hard time understanding how a longer or shorter tube has control over the amount of freon that can pass.well i will try to explain in a easyer way to understand.now everyone i think knows that the size of a hole in the tube will alow only so much liquid to pass but.....if that liquid has to drag itself along the walls of the tube it slows down and causes a backup (or pressure in this case)now if you shorten the distance it drags you effectively are allowing it to shortcut and run faster and less backup(lower pressure).this shortcut will put too much freon in the evaperator and effectively flood it too much resulting in not effecient heat removeal.(cooling in freon comes from the process of phase change from liguid to gas) if you do not allow it to boil off slowly enough it is pushed out and back to the compressor where it returns as a partial gas /liquid state .not cooling no where well as it was intended to do.so now you can see how inportant the size and lenght is.ok i am sendind a pic of my proto where you can see the capillary tube where i formed a nozzle from the end and how i attached the hose to the block with std ac hose and fitting.i use a 1/4hp compessor seems to be the best choice between size and power.i use r22 it is realitively cheap compared to other freons.r134 works fine just not as effecient.
i am including links to calpillary tube charts and other helpfull pages.i dont think i have seen a forum anywhere that will have as much info as i am trying to give here so quick.i will try to anser questions as i can and have time to.i am a single dad of 2 children so i have my hands full alot..
