Anyone have a book on the proper line set size for a 5Ton AC using R410a?
Thanks!....

What's the size of the fittings?
I'm sure it would be designed for the correct size.
Also check the manuals.

You can't always go by the connection size found on the unit or this would eliminate the need for tables altogether. I have tables for R22 but not R410a.

A book about the lines of a 5 ton AC on R410a??

I have a book for a 3 ton and a 7 ton, can this help you any further?

Hi,
I can give you the line size if you tell me the followings :

1- Compressor capacity at design conditions.
2- Horizontal Pipe length (suction, liquid).
3- Vertical pipe length (suction, liquid).
4- Number and type of bends.

I have developed a pipe sizing programme and it is easy to size the pipes.

Cheers
