Pipe size?

[CRANK]

Can anyone tell me what size suction line i would require for a load of 23kw @-35 on r404a the distance would be about 50 metres with two risers.

Based on 23 kw @-35 C and 40 C condensing for R-404A at a 50m pipe run:
Suction Line = 2 5/8"
Liquid Line = 3/4"
Suction Riser= 2 1/8"
