1.5 HP, R-404, reach-in freezer. Changing out twin cap tubes for a one ton R-404 TXV.
Brazed in 5" by 1/4" OD copper where the cap tubes had been. Brought them together and brazed them into the end of a piece of 1/2" copper - to mate up with the TXV.
Then I realized that I could keep the TXV neatly inside the evap enclosure if I mounted it about ten-twelve inches further forward. So I left the 1/2" copper that long - rather than cut it down to 3" or so as I had originally planned.
My actual question is:
If I have the TXV outlet feeding a foot of 1/2" copper, Then two short 1/4" stubs, Then into the evap - will that create a problem?
My natural tendency would have been to make the 1/2" section as short as possible - a few inches. But to do that I have to mount the TXV outside the original enclosure. Which would look ugly. <g>
I hate to re-do the evap inlet - it was a huge bastard - no space - couldn't see - brazing by feel - no space to work - etc.
So? Will the 12" of 1/2" copper before my home-made 1/4" 'distributor' tubes make any difference?
