Table 6: Sizing Guidelines for Horizontal or Downow Suction Lines and Liquid Lines
NOTE: Target suction temperature loss less than 2.5°F.
Minimum suction line gas velocity target 1000 FPM
on horizontal and downow piping installations where
the evaporator is at or below the chiller elevation.
Maximum allowable suction line temperature loss
target 5°F; some selections are greater than 5°F
due to minimum velocity requirements at minimum
compressor speed.
