Hi guys, i am installing 30000 and 48000 btu air conditioners, with an average pipe run of 20 meters, the outdoor units are on the roof of this building.
The pipes are 3/8 discharge and 3/4 suction pipe.
My question is can i make this whole run with the same pipe size,i was thinking of using a 7/8 pipe on the vertical run on the 30000 btu machine and 1 1/8 (inch and eighth)for 48000 btu machine on the suction pipe only ,discharge pipe will remain the same.
What will be the effect on this.
I want to use this bigger size as a suction accumulator on the vertical rise of about 10 meters.
The pipes from the machine (indoor , outdoor) will be 3/4 from the flare nut then two meters will change to bigger sizes.Its copper pipe.
Unshared knowledge is as good as nothing.
