MI - 126-Apr-06 SUCTION & LIQUID line SIZINGTYLER SPEC GUIDESUCTION & LIQUID line SIZING CHARTSUSING line SIZING CHARTSB asisThese line SIZING CHARTS are based on a SUCTION pressure drop equivalent to a 2 F change in saturationpressure and LIQUID line pressure drop of 5 psi. For R-404A Low Temperature 1 psi; for R-404A and R-22 Medium Temperature 2 psi is used. This is the maximum allowable pressure drop for the entirepiping run regardless if it is 50' or 250'. The advantage of the graphic representation of this information is to show just how close to full capacity a particular selection is. This is true for both thecondensing unit capacities on the individual specification sheets or the separate SUCTION line sizingcharts.
the vertical equivalent footage line. The area in which the plotted point falls in the recommended line size. Liquid Line Sizing Due to the lack of space, the specification sheets have just one column for a liquid line size. The line sizes given on the specification sheets are based
