R410a Refrigerant tubing sizing....
(OP)
We are looking at designing chiller packages using R410a refrigerant. The problem I have is selecting the tube size for R410a pressures. Using the ASME B31.5-2006 only allows me to go up to 7/8" copper lines with R410a working pressures (Type K, annealed copper). Is there another type of copper available for use with R410a for larger (1-3/8 to 1-5/8) copper lines?

Your post caused me to review the specification ASTM B31.5 and I realized the annealed value has to be used with Type K and L but not with ACR tubing.
Thank you.
