Tube Advice

[Icy]

I could do with some pipe advice i just got a package from Bes and they put the wong tube in they gave me 15m of 1/2 instead of 3/8 would this make alot of difference to my system if i used 1/2 instead of 3/8 or shall i just keep it? it also cost a few pounds extra but they did not charge me for it. Really could do with some quick advice so if there is a problem i can arange to get it changed asap.

Thanks all :D

I need some 1/2" you can send it over here and buy some 3/8" :D

I dont think it will make alot of difference, its just harder to work with and you will need to reduce on a few fittings which is not ideal.

exactly what parts of the system should use what OD tube? also depends on how much of my system will use it as well. as i know that from the compressor to the condenser its going to need 3/8 i guess i could just use the 1/4 over it and braze the inside then i dont have to swag it out to fit tubes together. Also depends if im going to ever need 1/4 in the future because if i am i might as well keep it and save my self a bit of cash and go buy some 3/8 as well.

Suction side, 5/16" or 3/8", Discharge 3/16" or 1/4"

So 1/4" from discharge to condensor, condensor to filter, captube from filter to evap, 3/8" suction back to the compressor inlet. I know that a lot of condensor's have 3/8" fittings and if you really wanted to I suppose you could run 3/8" from compressor to condensor, but it's not needed really.

1/2" is used at times on larger systems but its not really a big issue for smaller ones. you should keep the 1/2" tho, cos 1/2" and 1/4" makes a decent heat exchanger coil.

Should pick up some 3/8" too though. If you plan to start doing more phase, you'll find that you seem to need every size after a while :rolleyes:

ah bugger it might as well just keep it rofl. can all ways get some more. besides im thinking of making my watercooling system out of it heh. thx for your advice Johann how much do you need btw? might be able to send u a bit for a little xmas pressent lol. yeah will order some 3/8 later today. Think i could use 1/4 as a desuperheater? if so how much tube and what diameter would you suggest?

[Icy]

also how exactly does a desuper heater work? is it just to cool the gas a bit more before it goes into the condenser? I was thinking that maby a small Coil after the condenser would be good to make sure all the gas is cooled maby one using 1/4 just before the dryer/valve with a 3 inch diameter and about 10 coils tall just to make sure its all turned to liquid.
