MODEL AWV CHILLERS
Table 6:
Sizing Guidelines for Horizontal or Downflow 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 downflow 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.
